A blower housing having a resilient bottom piece and a rigid top piece assembling with the bottom piece is provided. The top piece includes a plurality of depending legs which are urged against a matching plurality of flanges formed in the resilient bottom piece to cushion mount the top piece to a furnace or the like. A plurality of mechanical fasteners such as screws or the like extend through a plurality of lugs on the top piece and through the flanges to urge the depending legs against the flanges and the furnace. Through this construction, a generally rigid connection between the motor mounting plate and the furnace is achieved while providing the sound and vibration attenuation of a resilient housing.

A thermal ink-jet head comprising: a heater substrate having heating elements; a channel substrate having a plurality of ink supply ports, an ink reservoir, a plurality of nozzle flow channels, the ink reservoir being common to communicating directly with each nozzle flow channel, and a slanted wall, wherein said channel substrate is formed with at least said plurality of nozzle flow channels disposed therein, said nozzle flow channels extending to respective end portions of said heating elements, the ink supply ports and said ink reservoir supplying ink to said plurality of nozzle flow channels, a sectional area of said ink reservoir communicating with said ink supply ports being increased from said ink supply port toward said nozzle flow channel, a synthetic resin layer is provided on a heater substrate, the heating elements also being provided on said heater substrate, and an ink flow channel having a throttle is formed in said ink flow channel, said ink flow channel and said throttle being provided in said heater substrate, said throttle being defined between the heater substrate and the slanted wall of the channel substrate, said throttle extending from substantially the end portion of said heating elements to substantially said ink reservoir formed in said channel substrate, and a sectional area of the throttle decreases in size in a direction from said ink reservoir to said heating elements. 6. A combination of a recording apparatus and a thermal ink-jet head, said recording apparatus comprising a housing and an ink tank placed in said housing, said ink tank having openings, said thermal ink-jet head comprising: a heater substrate having heating elements that produce bubbles; and a channel substrate having a plurality of nozzle flow channels, an ink reservoir, a plurality of ink supply ports and a slanted wall, the ink supply ports communicating with the openings of said ink tank, the ink reservoir being common to communicating directly with each nozzle flow channel, wherein each of said nozzle flow channels are formed in said channel substrate, said nozzle flow channels extending above the heating elements to substantially an end of said heating elements, and an ink flow channel is provided in at least said heater substrate, said ink flow channel forming a throttle between the heater substrate and the slanted wall of the channel substrate, a sectional area of the throttle being decreased in size as it approaches said heating elements from said ink reservoir. 7. A thermal ink-jet head comprising: heating elements formed in a heating substrate, said heating elements being disposed in a pit formed in the said heating substrate; an ink reservoir; a channel substrate having a slanted wall and a plurality of nozzle flow channels having a portion disposed above said heating elements, the ink reservoir being common to communicating directly with each nozzle flow channel; and an ink flow channel between said ink reservoir and said nozzle flow channel, said ink flow channel forming a pathway so that ink flows between said ink reservoir and said nozzle flow channel, a throttle being formed within said ink flow channel between the heating substrate and the slanted wall of the channel substrate, said throttle having a sectional area that varies in size between said ink reservoir and said nozzle flow channel. 8. The ink-jet head of claim 7, further comprising a cut away section provided in said heating substrate proximate to an end of said heating elements opposing said ink flow channel. 9. The ink-jet head of claim 7, wherein said nozzle flow channel has a tapered wall extending perpendicular to a direction of ink flow in said nozzle flow channel. 10. The ink-jet head of claim 7, further comprising a tapered channel pressure wall formed at an end of said nozzle flow channel and substantially above the end of said heating elements. 11. The ink-jet head of claim 10, wherein said throttle is disposed substantially below said tapered channel pressure wall. 12. The ink-jet head of claim 10, wherein said tapered channel pressure wall controls a growth of a bubble produced on said heating element. 13. The ink-jet head of claim 12, wherein said channel pressure wall reflects the bubble toward an ink discharge port. 14. The ink-jet head of claim 12, wherein the throttle causes the bubble to form in a direction of the ink discharge port. 15. The ink-jet head of claim 7, wherein a portion of the ink flow channel forms the pit. 16. The ink-jet head of claim 7, wherein the sectional area of the throttle decreases in size from said ink reservoir to said tapered channel pressure wall.
