Title: Scroll compressor
Inventor: SAITO AKIRA
IPC: F04C18/02
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of the bearing fitting part of a drive shaft and increase the supply of lubricating oil to the front over a bearing to improve the lubricating property of a lip seal by partially cutting the circumference of the bearing fitting part of the drive shaft in the extending direction of the drive shaft. SOLUTION: When a shaft 11 is rotated through an electromagnetic clutch 15 by an external driving source, a movable scroll 20 is rotated, and the fluid run into an inlet chamber 18 is carried into the pocket between spiral bodies 16b, 20b. The volume of the closed pocket is reduced according to the movement of the pocket, whereby the fluid is compressed, and the compressed fluid is discharged from a discharge port 16a1. In this case, the circumference of the major diameter part 11b of the shaft 11 is partially cut out in the axial direction, whereby the weight is reduced. A lubricating oil passage is formed between the inner race of a ball bearing 13 and the major diameter part 11b by this cutout, and the feed quantity of the lubricating oil to the front over the ball bearing 13 is increased.

Title: Voltage-dividing circuit
Inventor: FUJITA HIROSHI
IPC: H03H11/46
Filed: 1990-07-11
Abstract: PURPOSE:To prevent an error from occurring in a voltage-dividing output even if the difference of an input voltage becomes larger and to obtain high linearity by constituting a circuit so that respective base-emitter voltages of first and second transistors become equal in spite of the difference of the input voltage. CONSTITUTION:Since currents dI and dI' are R1+R2=R3, the sizes are equal and only directions differ. Since the sizes of the currents dI and dI' are equal, they cancel each other and the emitter current of the first transistor(Tr) Q1 turns into the current I0 of a current source I and becomes constant in spite of the sizes of dI and dI', namely, the size of V1-V2. Thus is the same as the emitter current of second Tr Q2, and respective base emitter voltages of first Tr Q1 and second Tr Q2 are equal even if the difference of V1 and V2 becomes larger. Consequently, the occurrence of the error is prevented in the output voltage of an output signal (r) and high linearity can be realized even if the difference of V1 and V2 is a large area.

Title: Gate bias circuit for multistage fet amplifier
Inventor: WATANABE JUN
IPC: H03F3/16
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To prevent the undesired oscillations which are produced by application of the gate bias voltage. SOLUTION: When a control signal S is inputted to a delay circuit 1, a switch 4 opens with fixed delay and the operating gate voltage is applied to a gate terminal 51 of the FET existing at the stage nearest the input via the bias resistors R1 and R2. Then a switch 5 opens with larger delay when the signal S is inputted to a delay circuit 2, and the operating gate voltage is applied to a gate terminal 52 of the FET of the 2nd stage via the bias resistors R3 and R4. In the same way, the operating gate voltage is applied to a gate terminal 53 of the FET of the 3rd stage with delay longer than that of the 2nd stage FET. As a result, an input open state is not caused when the FETs of the 2nd and 3rd stages operate and therefore the undesired oscillations are never produced.

Abstract: PURPOSE:To enlarge the width of a gate approximately twice the width in a conventional linear stripe design for a 50% reduction in ON resistance by a method wherein a stripe-geometry gate is provided, so irregularly configured as to alternately surround the contact sections of sources and drains arranged longitudinally and transversely on the surface of a semiconductor substrate at prescribed intervals. CONSTITUTION:Each horizontal power MOSFET consists of a polycrystalline Si gate electrode 1, a source contact hole 2, and a drain contact hole 5. Gates 1 are so arranged that they assume a cranked shape suggesting rectangular waves. A source contact hole 2 is accommodated between two neighboring gates 1, and a drain contact hole 5 is accommodated in the same manner on the other side. A channel formed on the semiconductor substrate surface just under the gate insulating film is without interruption along the gate. There is no useless part in this design at all, which realizes a channel wider per unit area and a heavier drain current. Accordingly, resistance is lowered in the channel section, which in turn enables the ON resistance to be reduced.
