Abstract: PURPOSE:To obtain a common-gate transistor having a high stability and a high- gain by selecting a value of a parasitic inductance due to a gate connecting line, a metalized pattern for common-gate and a gate bridge portion to a parasitic capacity properly. CONSTITUTION:A gate connecting line 6 having 2 lines and a parasitic inductance LO having 1.5mH are applied by using an electrostatic induction transistor pellet 5 abolishing a gate bridge. The parasitic capacities of the pellet 5 in drain-gate, gate-source and drain-source are approximately CDG=3pF, CGS=6.5pF and CDS= 3pF respectively. The package capacity CDS is neglegible to these described above. In this case, a high-gain and a high stability such as 15.1 of stability coefficient at max. high-gain 12dB is obtained becoming CO 16pF of an equivalent gate capacity and approximately 1GHz of a series resonance frequency with LO. Thus, when the parasitic inductance in relation to the gate is selected according to the parasitic capacity value and these series resonance frequency is set within a range of frequency used by the transistor, a common-gate device having a high stability is obtained.

Abstract: PURPOSE: To not only damp the three dimensional vibration, but also damp the small/ medium vibrations in the vertical and horizontal direction in an effective manner by providing a three dimensional vibration damping part, an elastic body, and a vibration absorbing member, and providing a sleeve-shaped elastic member and a rigid member. CONSTITUTION: When impact energy of pitching and rolling is simultaneously transmitted to a lower fitting plate 14, a vibration damping part 20a and a vibration absorbing member 18 are deformed to damp the vibrations in the vertical and horizontal direction. When a large horizontal displacement is applied in the rolling, the shear deformation is generated in a three dimensional seismic isolator 16. The damping part 20a is deformed in the horizontal direction while it is compressed. The vibration absorbing member 18 is also deformed, but the deformation exceeding the deformation due to the synergistic effect of the elastic member 22 and the rigid body 24 is not advanced. The small/medium vibration are damped by absorption elements 26, 28 and the elastic member 22.  The radial length W of the damping part 20a is larger than the thickness (t), and the radial length S of the space of a direct connection part 20b is smaller than W. Safety is improved, and the manufacturing cost is suppressed.

Filed: 1986-07-09
Abstract: PURPOSE:To improve the driving characteristic at the time of backing while ensuring the driving performance at the time of advancing by differentiating the engine output controlling quantity of a vehicle with a manual transmission between a clutch operating time and no operating time at the times of advancing and backing of said vehicle. CONSTITUTION:On receiving an accelerator opening alpha, a backing-vehicle gear position signal of a transmission 3, and a complete clutch connection signal of a clutch stroke sensor 8, a control unit 5 determines the gain of a throttle opening corresponding to the received accelerator opening alpha to a defined target throttle opening which is lower than any one at the time of advancing a vehicle, and carries out feedback control by the signal of a throttle opening sensor 6 through a DC motor 9. Thereby, the resolution of the throttle opening is improved more than when a vehicle is advancing, to obtain a good drivability improving traveling stability. When the signal of the disconnection or half connection of clutch is received, the gain of the throttle opening with respect to the accelerator opening is determined to be the same as the first gear of advancing, thereby, preventing the occurrence of an engine stall at the time of connecting a clutch.

Filed: 1982-09-14
Abstract: PURPOSE:To enable to maintain an inverter device in a stable operation even at the switching time of a frequency command signal by providing a current transformer, a timer circuit and a clamping circuit, and clamping the output voltage of the inverter device to 0V by the clamping circuit during the period for converting the two types of frequency command signals. CONSTITUTION:When a switch 20 is turned ON, an inverter device outputs a frequency and a voltage in accordance with a signal which is applied by the first frequency setter 10. When the switch 20 is turned OFF to output a signal from the second frequency setting circuit 19 and the switch 21 is turned OFF, a signal is applied to a timer circuit 22 before the switch 21 is turned ON. The timer circuit 22 always monitors the output from a current transformer 5 and outputs the time ON signal inversely proportional to the inverter output current. A converter 1 is interrupted at the gate during the period of this signal, the output of the converter 1 is interrupted, a switch 6 is turned ON, and the charge of a capacitor 3 is consumed by a resistor 7. Two types of pulse frequency command signals are switched in the shortest time irrespective of the state of the load of an inverter, thereby maintaining the stable operation.

Title: Electron beam exposing method
Inventor: MACHIDA YASUHIDE
IPC: H01L21/027
Filed: 1985-07-19
Abstract: PURPOSE:To simplify the calculation of pattern correction by a method wherein a plurality of patterns to be exposed are classified into the pattern group arranged periodically to properly select the optimum correction amount of pattern and the amount of irradiation, and the minimum interval producing no proximity effect between patterns is set as the mutual interval. CONSTITUTION:The patterns with which a memory storage is constituted are divided into a memory element group 1 and a driver part 2, and extraction points SPP1-SPPn are provided on the side of patterns PP1-PPn which constitute the above-mentioned materials. The equation of developing energy E=Q1F(r1)+Q2F(r2)+...+QnF(rn) is set up at each point with the amount of irradiation of Q and the exposure and scattering intensity of F, and the correction pattern (indicated by a broken line in the diagram) for each pattern PP and the amount of irradiation Q are calculated by solving the quadratic equation. The distance 3, having the superposition of proximity effect in the vicinity of the memory element group 1 and the driver group 2 smaller than the developing energy, is found and it is used as the mutual interval. Practically speaking, as the amount of irradiation of the correction pattern of the group 1 is already known in most cases, the calculation of the dosage of irradiation of correction pattern for driver and the calculation of the distance 3 are sufficient, thereby enabling to remarkably reduce the calculation to be performed for the entire device.

Filed: 1984-07-30
Abstract: PURPOSE:To permit accurate detection of current only during a call by permitting selective setting of a reference voltage supplied to a current detection transistor in a loop dial trunk according to the line resistance. CONSTITUTION:The base of a transistor Tr 1 is connected to an input terminal IN through a resistor r1. The resistances of resistors r1-r5 are set such that a voltage VR produced across a resistor R2 when a current i is caused in response to a signal from an exchanger 2 and a voltage V' produced across the resistor R2 when the transistor Tr 1 is turned on are equal. Thus, reference voltages -e1--e3 which are provided by resistors r2-r5 can be selectively applied to the base of the transistor Tr 1 according to the line resistance R, and it is possible to prevent detection of a pseudo call current that may otherwise be produced due to a source voltage difference.

Title: Measuring device
Inventor: IIDA SUEZOU
IPC: G08C19/30
Filed: 1981-10-08
Abstract: PURPOSE:To sufficiently improve the follow-up characteristics of analog-digital converters to variation in load cell output with variation of a stabilized pan, and to secure fetching operation for count data from the analog-digital converters. CONSTITUTION:Balance parts 4 and 5 are provided so that load cells LC1 and LC2, and AD converters ADC1 and ADC2 correspond to each other. Therefore, each AD converter fetches a load cell output at a relatively short period to perform data processing, and also follows up variation of a stabilized pan with a load sufficiently. A timing circuit 6 delays the starting of the voltage signal fetching operation of the AD converters ADC1 and ADC2 by enough time (tens- hundreds musec) for flicker preventing processing. Consequently, a CPU1 inputs count data from both AD converters ADC1 and ADC2 at invariably different timing.
