IPC: F02B77/13
Filed: 1986-06-26
Abstract: PURPOSE:To attain the silencing of a selective sound and to simplify the maintenance and inspection of the device because a microphone which has a little durability isn't used by detecting the oscillation of a noise generating source so as to make a control sound.

Title: Regenerative pump
Inventor: SENOO YASUTOSHI
IPC: F04D29/66
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To reduce noises caused by the intermittent collision of a fluid against a partition wall by forming a pressure rising passage leading to a discharge passage from a suction passage so that the flow of the fluid flowing into an impeller is gradually reduced toward the discharge passage side. SOLUTION: When an impeller 4 having a large number of grooves 5 circumferentially formed on both faces of an outer peripheral part and forming each space between the adjacent groove parts 5 as a blade 6, is rotated, a fluid flowing into a pressure rising passage 8 from a suction passage 1 flows into each groove part 5, flows out again to the pressure rising passage 8 in association with the rotation of the impeller 4 and flows into the root of each groove part after exchanging momentum with the fluid in the pressure rising passage 8. The fluid thereby flows spirally along the circumferential direction of the impeller 4, but since the width A of the pressure rising passage 8 is gradually narrowed on the discharge passage 2 side of the pressure rising passage 8, the quantity of the fluid flowing into the root of each groove part 5 from the pressure rising passage 8 is gradually reduced, and the generation of vortex flow is suppressed near a partition wall 9 to suppress the generation of noise caused by the collision of the fluid against the partition wall 9.

Title: Capacitor-excitation type brushless self-exciting synchronous generator
Inventor: KANEHARA MIKIO
IPC: H02K19/26
Filed: 1979-11-15
Abstract: PURPOSE:To prevent the hunting of a relay by connecting a rectifying element in series with an exciting coil of a solenoid relay having normally closed contact for shorting a part of a load winding and operated by a stator winding and in parallel with a capacitor. CONSTITUTION:When a rotor 4 is rotated, small amount of lead current Ic will flow in the capacitor-excitation winding 2 by the residual magnetic flux of the rotor 4. Thereafter, the lead current Ic will then increase gradually by the self- excitation effect thereby estabilishing a voltage. Since the part 1a of the load winding 1 is shorted with the normally closed contact 10 at the time of starting, a voltage is established at a relatively low rotating speed. After the voltage is established, the solenoid relay 9 is operated by the output of the load winding 1, and the contact 10 is opened. Even if the rotating speed is decelerated in no load state so that the voltage Ea is abruptly lowered, the charged voltage of the capacitor 13 is applied to the coil 11. Accordingly, the relay 9 is retained for a while in excited state.

Title: Manufacture of semiconductor device
Inventor: HAYAMA NOBUYUKI
IPC: H01L29/73
Filed: 1986-06-24
Abstract: PURPOSE:To improve high-frequency characteristics and increase a switching rate by arranging each electrode for a hetero-junction bipolar transistor in a self-alignment manner. CONSTITUTION:Since an emitter electrode 16A and an emitter region are formed by the same mask, both size can be set at approximately the same value, thus also fining the emitter region by making an emitter mask 18 minute. Since a base electrode 21A is disposed to the emitter electrode 16A in a self-alignment manner through a first insulating side wall 19, the film thickness of the first insulating side wall 19 is set at a small value, thus shortening the distance of the base electrode 21A and the emitter region, then largely reducing parasitic base resistance. Since the width W of the base electrode 21A is specified by the sum of the thickness of a base electrode film 21 and a second insulating side wall 20 in the first insulating side wall 19, the thickness of the base electrode film 21 or the second insulating side wall 20 is set at a small value, thus setting width W at an extremely small value. Accordingly, parasitic capacitance between a base and a collector can be reduced largely.

CONSTITUTION:A direct recording developer 11 has a printing part wherein a number of pin electrodes 15 are arranged in a line on a sleeve 16 provided outward with a magnetic roller 14 in the vicinity of the photosensitive body 1a of a photosensitive drum. The magnetic roller 14 faces, with the polarities N and S, the sleeve 16, and when the roller 14 is rotated, magnetic toner 13 sticking to the surface of the sleeve 16 moves.
