Patent JP-H03217119-A (JP)
Title: Cmos buffer circuit
Inventor: HAMADA MASANORI
IPC: H03K19/0948
Filed: 1990-01-23
Abstract: PURPOSE:To keep the rise and the fall of the final output waveform sharp to prevent the occurrence of harmonic noise by dividing an input signal to two systems, and reducing the inclination of the leading edge of a square wave signal on the former line, and reducing the inclination of the trailing edge of the square wave signal on the latter. CONSTITUTION:When a square wave is inputted to an input 1, a supply potential (VDD) is applied to the gate of an N-type MOSFET 5 on one of signal lines divided to two systems and this MOSFET is turned on. However, the on-state resistance is different by the signal level and the output is raised to only about VDD/2 in the quick operation. Therefore, the signal is converted to a signal having a slower trailing edge by a MOS inverter 7, whose threshold level is higher than VDD/2, and is transmitted to the gate of a P-type MOSFET 1. The P-type MOSFET 3 converts the signal to a signal having a slower leading edge contrary to a P-type MOSFET 2, and the signal is transmitted to the gate of an N-type MOSFET 4.

Title: Memory writing method for analog signal
Inventor: HATTORI YASUSHI
IPC: G11C27/00
Filed: 1989-01-25
Abstract: PURPOSE:To reduce the memory capacity necessary for recording by making the object of sampling the mean value of the levels of analog signals obtained in a sampling period. CONSTITUTION:An A/D converter 21 detects the level of an analog signal D at the rise point of a clock signal C and converts the level into the data E to output it. An adder 22 adds together the values of 10 pieces of data E which are inputted for a period of a clock signal A and outputs the data F. A divider 23 latches the data F at the rise of the signal A and outputs the data G on the value obtained by dividing the value of the data F by 10. A register 24 latches the data G at the rise of a clock signal B and outputs the data H. Then a control circuit 30 outputs the data H to a memory 60 as the data J and at the same time outputs an address signal I and a write pulse K in the timing corresponding to the data J. Thus the quantity of data written into a memory can be compressed. As a result, the memory capacity necessary for recording can be reduced.

IPC: B41J2/44
Filed: 1992-01-29
Abstract: PURPOSE:To correct deviation in the voltage-light intensity characteristics of a variable aperture element which utilizes electrooptical effect. CONSTITUTION:The polarity of the DC bias voltage applied from a power source 8 to aperture areas of the electrooptical crystal plate 1 in common is inverted by a switch circuit 7 at a specific period. When the polarity of a high- frequency pulse signal applied to each of the aperture parts is switched according to an image signal to open the aperture part, the pulse signal is applied having the same polarity with the bias voltage, but when the aperture part is put in a cutoff state, the pulse signal having the reversed polarity from the DC bias A voltage is applied.

Title: Anti-skid brake device for vehicle
IPC: B60T8/66
Filed: 1991-02-05
Abstract: PURPOSE:To stably improve braking ability regardless of the variation of operating conditions by providing a starting condition varying means to vary the threshold of the control starting condition of an anti-skid control means according to the operating state of a brake pedal. CONSTITUTION:Various kinds of data are inputted in a control unit 24. In the case where the quantity B1 of pressing down a brake pedal, the quantity of the variation B2 of brake fluid pressure and the quantity of the variation of pressing force B3 exceed fixed values, the present state is judged to be one being apt to slip, and the threshold, which functions as anti-skid control starting condition, of the deceleration of wheel speed is therefore set up to a slightly lower value, namely -1.5g. When wheel deceleration exceeds the threshold of -1.5g, the anti-skid control begins. When one of the above data B1, B2, B3 is not above its fixed value, the threshold of the deceleration of the wheel is set up to -3.0g. In this case, when the wheel deceleration is not above -3.0g, the wheel is not judged to be a locked state and the anti-skid control does not start.

Title: Play vehicle
Inventor: ICHIKAWA KAZUFUMI
IPC: A63G25/00
Filed: 1988-01-27
Abstract: PURPOSE:To considerably improve the running capacity and to simplify the structure by providing a rear wheel steering mechanism which steers a rear wheel in the direction having a phase equal or opposite to the phase of the steering direction of a front wheel. CONSTITUTION:A knuckle member 22 is coupled to a coupling member 21 and is rotated through a coupling rod members 42 and 43 to change the direction of rear wheels 2c and 2d. A bracket 40 constitutes a rear wheel steering mechanism 4 together with a T-shaped bracket 41, coupling rod members 42 and 43, and a coupling rod 44. The steering direction of rear wheels has the opposite phase when the rear end part of the coupling rod 44 is coupled to the side of an arm part 41a, and this direction has the same phase when it is coupled to the side of an arm part 41b. Consequently, since the minimum radius of rotation is made smaller than that of a play vehicle having a 2WS mechanism, the course layout is narrowed and the running capacity adapted to a vehicle running course is easily obtained.

Title: Generator circuit of interruption signal
Inventor: MORIMOTO TAIJI
IPC: G06F13/24
Filed: 1980-02-07
Abstract: PURPOSE:To perform an assured interruption process, by accepting the interruption pulses produced in a specified period. CONSTITUTION:The signal B of pulse duration t2 that is used as a gate switch signal of the gate circuit 4 is obtained in the form of the output of the fixed-duration pulse generator circuit 3 that is controlled so that the duration t2 may satisfy the equations of tN<t2-T3 and t2<ti<T1-T2 (tN: interruption inhibit period; ti: interruption process period with inhibition of interruption). Thus the interruption pulse (a) is accepted if the interruption inhibit period does not overlap the period t2. The interruption pulse to be accepted next is the pulse (d). The interruption inhibition period tN is defined as TN<t2-T3 when the inhibition period starts at the time point of (a), and accordingly the interruption pulse (c) is accepted. Thus the interruption signal produced during the interruption period is not accepted. Even to such a microprocessor, the interruption signal is accepted assuredly.

IPC: A47C7/38
Filed: 1993-02-01
Abstract: PURPOSE:To enhance the safety of an occupant at the time of collision, which produces a lateral load exceeding the prescribed load, by preventing a head part of the occupant from moving. CONSTITUTION:A portion of a seat belt 10, which is diagonally placed from a shoulder part to a waist part of the occupant, is formed into the form of hollow, airtight bag, and the hollow part is connected to a gas pressure generator 24.

Title: Circuit for measuring oxygen concentration
Inventor: YAGUCHI OSAMU
IPC: G01N27/41
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To reduce measurement errors and improve reliability by grounding a non-inverting input terminal of an amplifier, connecting a resistor between an inverting input terminal and an output terminal, and connecting a limiting current type oxygen sensor between the inverting input terminal and a reference power source. SOLUTION: A non-inverting input terminal of an amplifier 30 as an operational amplifier is grounded, a detection resistor 32 is connected between an inverting input terminal and an output terminal, and a limiting current type oxygen sensor 34 is connected between the inverting input terminal and a negative reference power source 33. Since the non-inverting input terminal of the amplifier 30 is grounded, a detection current runs through the resistor 32 and the oxygen sensor 34 to make a voltage at the inverting input terminal 0 V. A cell voltage never changes even when a limiting current value (oxygen concentration) of the oxygen sensor 34 changes. In consequence, an output voltage of the amplifier 30 is correctly corresponding to the limiting current value of the oxygen sensor 34. Sensitivity of a measurement circuit is increased as a resistance value of the resistor 32 is increased, and at the same time, a rush current to the oxygen sensor 34 can be limited small.
