Title: Fuel controlling apparatus for internal combustion engine
Inventor: SAWAMOTO KUNIAKI
IPC: F02D41/24
Filed: 1982-07-02
Abstract: PURPOSE:To enable to measure the suction pressure of each cylinder under the same conditions, by measuring the suction pressure and the temperature of intake air when an intake valve is fully opened or in the state substatially equal to the same corresponding most correctly to the quantity of intake air, and providing a suction pressure sensor at a position located at a uniform distance from the intake valves. CONSTITUTION:Calculation is carried out in synchronism with a signal produced at a prescribed crank angle position. At steps P2, P3, it is detected whether an intake valve is fully opened or not. Further, the values of a suction pressure signal S1 and an intake-air temperature signal S2 are measured at a step P4, and these values are stored at a step P5 as the suction pressure and the temperature of intake air of a first cylinder. Since, with such an arrangement, the quantity of intake air for each cylinder can measured correctly, it is enabled to make the air-fuel ratio of each cylinder equal to each other.

Title: Paper detector for printer
Inventor: NODA KUNIO
IPC: B41J13/26
Filed: 1984-06-04
Abstract: PURPOSE:To detect the presence or absence of a paper, the wide of the paper and the inclination of the paper, by providing a paper-detecting means on a surface of a carriage moved in parallel to the platen which surface is opposed to the platen. CONSTITUTION:With the paper 3 fed to a printing-starting position, the presence or absence thereof is detected by some of reflection-type photo-sensors 12-14. Next, the carriage 8 is moved in the direction of an arrow F4 to detect the right end of the paper 3 by the sensor 12, and then the carriage 8 is moved at a fixed velocity in the direction of an arrow F3 to detect the left end of the paper. The width of the paper is obtained by dividing the velocity by the period of time over which an output signal from the sensor is ''1''. Then, the paper 3 is returned in the direction of an arrow F1 until the moment immediately before the output signal from the sensor 12 becomes ''0'', and when an output signal from the sensor 13 is ''0'' and that from the sensor 14 is ''1'', it is detected that the angle of inclination of the paper 3 is not larger than a maximum allowable angle of inclination. When both of the output signals are ''1'', it is detected that the angle of inclination is not smaller than the maximum allowable angle of inclination and the paper 3 is in a left-side upward condition, and when both of the output signals are ''0'', it is detected that the paper 3 is in a right-side upward condition.

Abstract: PURPOSE:To efficiently clean the upper surface of a kitchen iron plate without deteriorating the upper surface of the kitchen iron plate while preventing food refuses from making the iron plate dirty. CONSTITUTION:A kitchen iron plate 1 is conveyed by a conveyor 2. When the end part 12a of the kitchen iron plate 1 comes under the edge of a blade 31 inclined to the rearward of an elastic scraper 3, the first cylinder 51 and the second cylinder 52 are actuated so as to bring the edge of the blade 31 and the suction inlet 41 of a suction unit 4 set behind the edge of the blade 31 into contact with the upper surface 11 of the kitchen iron plate 1. Food refuses adhering to the upper surface 11 are removed by the edge of the blade 31 and sucked through the suction inlet 41. When the rear end part 12b of the kitchen iron plate 1 approaches the rear part of the suction inlet 41, the edge of the blade 31 is initially moved upward so as to remove food refuses adhering to the upper surface 31a of the edge of the blade 31 by the peripheral part 41a of the suction inlet 41. The edge of the blade 31 is then moved upward together with the suction inlet 41.

IPC: H03B23/00
Filed: 1981-07-23
Abstract: PURPOSE:To supply a frequency with very high accuracy in a short time, by detecting and correcting the error of oscillating frequency at each sweep. CONSTITUTION:An output frequency of a voltage controlled oscillator 1 is converted into a suitable low frequency at a frequency converter 12 with respect to an arbitrary frequency and inputted to a programmable counter 15 with gate circuit 14.

The memory is rewritten with the control voltage information after the correction and waits for the next sweep. The storage in a circuit 17 is coverted into an analog control voltage with a D/A converter 20 to control the oscillation frequency of the oscillator 1.

Title: Iris control circuit
Inventor: WATANABE MAKOTO
IPC: H04N5/232
Filed: 1991-05-20
Abstract: PURPOSE:To prevent the delay and hunting of the response of an iris when an object having high luminance enters a viewing angle by returning voltage which occurs in a Hall element to a limiter circuit. CONSTITUTION:A Hall element 4 is attached to an iris meter 3, and the output voltage of the Hall element 4 is amplified by a Hall element amplifier 14 and returned to a limiter circuit 11. Accordingly, when the iris meter 3 operates to open/close an iris 2, the change of magnetic field is given to the Hall element 4 and therefore, the voltage corresponding to the degree of the opening/closing of the iris is generated by the Hall element 4 and amplified by the Hall element amplifier 14 and so, the operation of the limiter circuit 11 can be controlled. Thus, by shallowing the level of controlling the amplitude of the limiter circuit 11 when the iris 2 is open or deepening the level of controlling the amplitude of the limiter circuit 11 when the iris 2 is stopped down, the ripple of a detection output for driving the iris can be made small, the hunting can be prevented and the response can be speeded up.

Title: Electric current memory cell
Inventor: DEIRUKU UOUTAA YOHANESU FURUUN
IPC: G05F3/24
Filed: 1992-05-07
Abstract: PURPOSE: To obtain a current sink type current memory cell which hardly responds to the variation of a substrate voltage and does not respond to a small number of charge carriers of a noise source on the same chip. CONSTITUTION: The current memory cell which samples the current I at a current terminal 5 during a sampling period and, at the same time, supplies a current to the terminal 5 during a holding period is constituted. A first switch S1 switches a PMOS transistor P1 to work as a diode during the sampling period and as a current source during the holding period. The current at the terminal 5 is copied to the transistor P1 during the holding period and the current of the transistor P1 is copied to the terminal 5 during the holding period. Mirroring is performed by inverting the input and output of a current mirror circuit during the sampling and holding periods by using two NMOS transistors N1 and N2 and one inversion switch S2.  The current mirror circuit and PMOS current source are used together as a current sink that does not respond to a substrate voltage which is generated by a substrate effect.

Abstract: PURPOSE:To prevent a work machined surface from rust with electrode waste adhering to the work machined surface, by controlling average machining voltage to a side of voltage of reverse polarity, in the case of voltage of positive polarity and reverse polarity applied across an electrode and a work. CONSTITUTION:A machine, if it turns on a transistor T1, applies voltage of positive polarity from a DC power supply E1 to generate an electric discharge between an electrode P and a work W. Next the machine, turning off the transistor T1 while turning on a transistor T2, applies voltage of reverse polarity from a power supply E2. While the machine changes a value of variable resistance RV1 through a variable resistor RV1, smoothing circuit 1, comparator 2, voltage dividing resistors R3, R4, etc. in a control circuit controlling the transistors T1, T2, and the machine, changing an output VL of the smoothing circuit 1, varies an applying time of the voltage of reverse polarity. And if machining is performed by setting a pulse width for applying the voltage of reverse polarity so that average machining voltage becomes the voltage of reverse polarity, the machine, even if it interrupts machining, prevents a machined surface from rust by coating the machined surface with electrode waste adhering to the surface.
