Abstract: PROBLEM TO BE SOLVED: To analyze characteristics of non-operating condition of a transistor formed on a semiconductor crystal layer with accuracy by providing capacity connected between a side of resistance not connected to a drain terminal and a side not connected to a source terminal. SOLUTION: A value of a capacity Cb1, connected between a side of a resistance Rg connected to the gate terminal which is not connected to a gate terminal and a side of a resistance Rs connected to a source terminal which is not connected to the source terminal, is equal to a value of a capacity Cb2 connected between a side of the resistance Rg not connected to the gate terminal and a side of a resistance Rd connected to a drain terminal which is not connected to the drain terminal. As a new circuit constant, a capacity Csub is added. The capacity Csub shows capacity component through a conductive substrate. Since the conductive substrate is not depleted even under non- operation condition because it is provided with conductivity, it is required to consider the capacity component through the substrate.

Title: Actuation controlling method for hydraulic torque converter clutch in automatic transmission for vehicle
Inventor: ISHIKAWA KEIICHI
IPC: F16H45/02
Filed: 1987-01-30
Abstract: PURPOSE:To keep off any surging in a vehicle, by operating a clutch in a slipping state allowing the clutch to slip at the specified range where car speed is relatively low, but even in this range, when slippage of a hydraulic torque converter is less than the setting value, releasing actuation of the clutch. CONSTITUTION:When a clutch 22 is operated in a slipping state at a range where car speed is relatively low, if balance between actual output torque of an engine 2 and engaging force of the clutch 22 comes down and thereby the clutch is hard to slip, slippage of a hydraulic torque converter 3 is reduced, falling below the setting value. If it comes into such a state, actuation of the clutch 22 is released, a torque variation due to the slip of the hydraulic torque converter 3 is absorbed, and thereby any surging in a vehicle is prevented from occurring, thus a feeling of driving quality is made so better.

Abstract: PURPOSE:To prevent dusts in a case from flowing out to a cassette section where semiconductor wafers are contained, by a method wherein the air in the case is smoothly circulated by directly joining the upper and lower parts of the case containing the upper and lower drive parts by means of a pipe provided outside the case. CONSTITUTION:In case the drive part 2 moves up, the air in the case 7 flows in directions of arrows A and B, entering the pipe 9 through the upper opening 7a of the case 7, passing through its lower opening 7b, flowing in directions of arrows C and D, and circulating through the case 7. On the other hand, in case the drive part 2 moves down, the air in the case 7 flows so as to circulate in the directions reverse to the case of upward movement. As a result, dusts flow out of the gap between an arm 3 and a shutter 8 and do not exert adverse effect to the semiconductor wafers 5 in the cassette 6 held by a chuck 4; thus, the yield of products can be improved.
