Title: Fuel injection control device
Inventor: SASAKI SHIGERU
IPC: F02D41/10
Filed: 1984-09-06
Abstract: PURPOSE:To make the rise-up characteristic of an engine satisfactory upon transition, by providing an asynchronous fuel injection means which carries out a predetermined amount of asynchronous fuel injection when a transition detecting means detects that the engine is in a predetermined transition condition. CONSTITUTION:A fuel injection control device II in an internal combustion engine I computes a fuel injection amount in accordance with the load of the engine I to carry out the main fuel injection. An asynchronous fuel injection means II-4 carries out the asynchronous fuel injection having a predetermined amount with respect to a certain engine cylinder which is selected with the result of detection by a crank angle detecting means II-2 and a rotational speed detecting means II-3 when a transition detecting means II-1 detects that the engine is in a predetermined transition condition. Thus, the rise-up of rotational speed of the engine may be made satisfactory upon transition of the engine.

Title: Current amplifying circuit
Inventor: YOSHIZAWA KAZUYUKI
IPC: H03F3/34
Filed: 1987-07-29
Abstract: PURPOSE:To eliminate a dark current and to control an auto bias level by obtaining a DC direct-coupled constitution. CONSTITUTION:Current mirrors are composed of npn type transistors Q1 and Q2 pnp type transistors Q3 and Q4, Q5 and Q6 respectively. Provided that, the emitter area of the Q6 is (n) times as large as the emitter area of the Q5, and the n-fold current of the current of the Q5 flows to the Q6. The current to flow to the Q1 goes to be equal to a direct current component of the current to flow from the emitter of a phototransistor Q0. Since the current equal to this flows from the Q4 to the collector of the Q0, the current to flow from the Q5 to the collector of Q0 goes to be equal to the alternating current component of the current to flow to the Q0. When the current of the Q5 is made n-fold and taken out from the Q6, only a signal current of the current to flow to the phototransistor Q0 can be n-fold and taken out to a terminal I0.

Filed: 1988-07-27
Abstract: PURPOSE:To improve tracking errors significantly by performing a data analysis on a magnetic characteristic of a magnet used in an instrument from a scale characteristic thereof to achieve a remagnetization of the magnet based on the data. CONSTITUTION:A moving-coil 52 is fed with a current from a DC power source 56 to rotate the moving-coil. The coil 52 is turned according to the current supplied and a virgin magnetizing characteristic of the magnet 51. A computer CPU 10 performs an image processing of an angle of oscillation of the coil 52 corresponding to a value of the current applied to determine linearity. At the same time, the CPU 10 controls magnetizing currents to be supplied to magnetizing coils 31-34 for each coil according to the linearity. With the control of the currents, magnetic fluxes interlinking of the magnet 51 change to the fullscale from zero in the angle of oscillation of the coil 52. As a result, a magnetic distribution of the magnet 51 reaches a target value to improve the linearity, thereby enabling a reduction in the tracking error to + or -0.2.

IPC: G03B21/11
Filed: 1983-10-07
Abstract: PURPOSE:To enable identification of plural kinds of marks for retrieval with one mark detecting element by counting the pulses generated while the marks are detected and discriminating the size of the marks from the count value thereof. CONSTITUTION:A mark detecting element consists of one photoelectric element 37 and attains an L level when the incident light is shielded by a mark 36 passing by said element, thus providing a mark detection signal. A pulse generating means generate pulses by a pair of a light emitting element 40 and a photodetector 41 which face each other with a pulse disc 39 in-between. The direction of the pulses is discriminated by utilizing a signal for detecting the feed length of a film or the like. The pulses generated while the element 37 detects the marks are counted and the size of the marks is discriminated by the count value thereof. Discrimination of plural kinds of the marks for retrieving frames is thus made possible with one detecting element.
