Title: Reaction mechanism for brake booster
Inventor: KOBAYASHI MICHIO
IPC: B60T13/52
Filed: 1982-09-27
Abstract: PURPOSE:To simplify the construction of a hydrostatic reaction mechanism by providing an elastic body to receive a hydrostatic pressure in a reaction chamber to be interlocked with an input shaft when the elastic body is elastically deformed for transmitting reaction to the input shaft. CONSTITUTION:A hydrostatic reaction chamber 50 is formed by a seal member 52 and an elastic body 52 between an input shaft 17 and an output shaft 32. When the peripheral support metal of the elastic body 53 is brought in contact with a stopper ring 55 of the output shaft 32, the periphery of the elastic body 53 is fast fixed on the output shaft 32. Meanwhile, a reinforcing ring 56 on the inside of the elastic body 53 is oppositely arranged with a fixed gap 8 from a stage part 17d of the input shaft 17. For operating a brake, a hydrostatic pressure of the brake generated in a pressure chamber 45 of a master cylinder 2 is introduced into the hydrostatic reaction chamber 50 via a passage 57. While the pressure is low, the above-said gap 8 is maintained, and the reaction is not transmitted to the input shaft 17. When the above-said pressure is increased, the elastic body 53 is deformed to narrow the gap 8, and brought in contact with the stage part 17d. Consequently, the reaction is transmitted to the input shaft 17.

Title: Memory circuit
Inventor: INOUE YOSHINAGA
IPC: G11C11/41
Filed: 1991-07-09
Abstract: PURPOSE:To obtain a memory circuit having small chip size and short access time. CONSTITUTION:A data D is transmitted on a single data line 4b to the gate of an NMOS transistor 12. When the data D has a potential higher than a reference voltage Vref((l/2)Vcc), a PMOS transistor 11 is turned ON whereas an NMOS transistor 13 is turned OFF and an 'H' level is outputted to a pad 7. When the data D has a potential lower than the reference voltage Vref, the PMOS transistor 11 is turned OFF whereas the NMOS transistor 13 is turned ON and an 'L' level is outputted to the pad 7. Consequently, only one data transmission line 4b is required and the output is inverted before the potential of the data D goes 'H' or 'L' level. According to the invention, space factor of data transmission line is reduced and access time is improved.

Abstract: PURPOSE:To record a compression signal in a form of a digital signal by fractionalizing a luminance and a color data into a block structure with an encoder, and quantizing the data of a difference between the data of the block and either a minimum value or a maximum value with the number of bits less than the original one. CONSTITUTION:Digital data (the luminance and the color data) converted into the block structure are supplied from a multiplexer 13 to the input terminal 21 of an ADRC encoder 14. A detecting circuit 22 detects a maximum value MAX and a minimum value MIN of the block. (MAX - MIN) is calculated by a subtracting circuit 24 so that a dynamic range DR can be obtained. The output data of a subtracting circuit 25 and the DR are supplied to a quantizing circuit 26. The number of bits less than the original one is obtained by the quantizing circuit 26 so that the quantization adapted to the DR can be operated. Therefore, the compression signal can be recorded in the form of the digital signal, and the deterioration of the signal can be reduced.

Title: Semiconductor memory device
Inventor: SAKO TOSHIYUKI
IPC: G11C17/00
Filed: 1989-06-29
Abstract: PURPOSE:To realize high speed access by providing two or more dummy bit lines, and switching and supplying reference voltage to a differential amplifier through this dummy bit line. CONSTITUTION:A dummy memory 12 connected to a main body memory 11 side through the differential amplifier 13 is provided with two dummy bit lines Dbit1 and Dbit2, which are switched and used alternately by transistors 211, 212. Since differential input V3a charges the bit line 1a of the main body memory side of large capacity with electricity by the switching of a column address, it falls down to a grounding Vss side for a definite period. Simultaneously with this, reference differential amplifier input 3b falls too, and time to exceed reference bit line potential after the bit line of the main body memory side is switched can be shot. Thus, the high speed access becomes possible.

Title: Memory circuit
Inventor: TANIMURA NOBURO
IPC: G11C11/417
Filed: 1988-07-08
Abstract: PURPOSE:To attain a high speed access by connecting a digit line to a common data line through a column gate controlled by the output of a Y decoder and lowering the level of the digit line. CONSTITUTION:When information '1' is stored in a memory cell MS11, at the time of selecting a word line W1, transmitting gate MISFETQ3, Q4 are turned on. At this time, since a FETQ1 is turned off, to the serial connected loading means R11 of an enhancement type MISFET, a current does not pass but the digital line D11 goes to a high level lower by a voltage twice as high as the threshold voltage of the FET from VCC. A loading means R01 generates a comparatively large voltage deterioration to bring the digit line D01 to a low level. Thereby, the output lines C1-Cn of the Y decoder 3 go to a comparatively low level, from which the FETQ5, Q6 of a column input and output circuit 4 are turned on to transfer data at high speed.

Filed: 1980-11-29
Abstract: PURPOSE: To reduce the generation of fluctuation in output torque by providing a variable capacity clutch between an output shaft of an engine comprising plural power sources and a transmission where the transmission torque is set between a peak torque of the power source and an average torque.  
     CONSTITUTION: When a desired torque is increased and an accelerator is stepped on, a microswitch 69 operates and a clutch 42 is connected, thus allowing both first and second engines 1 and 2 to be connected to an output shaft 42. At the same time, a signal is transmitted to a pulse width change circuit 78, permitting a pulse generating circuit 79 to generate a signal to change the width of pulse. With this construction, the transmission torque capacity of a solenoid powder type clutch 71 is increased and changed to approx. 1.4 times the average torque Tm of the total outputs of the first and second engines 1 and 2. A peak torque Tmax is cut and transmitted to a transmission 72.

Title: Internal combustion engine having plural power sources
Inventor: YAMAKAWA TOORU
IPC: F02D25/00
Filed: 1980-11-29
Abstract: PURPOSE: To make the action of break effective by using a combination of plural power sources not only for a greater required torque but also the range of engine brake.  
     CONSTITUTION: When an engine brake is applied, the revolution from the wheels forcibly drives a crank shaft 6 of a first engine 1, thereby increasing the negative pressure inside a throttle cylinder 55 and turning on a negative pressure switch 71. An accelerator switch 79 detects that the accelerator has not been stepped on beyond a specified value and outputs both signals to a decision circuit 81. The decision circuit 81 decides that the engine brake has been already  applid from the detection of both signals, and outputs a control signal. A drive circuit 83 forces a control current to flow into a coil 84, thereby directly connecting a solenoid type clutch 42 and starts the second engine 2, using the unit as a four-cylinder internal combustion engine.
