Title: Fuel injection control equipment at engine start
Inventor: ANZAI KATSUSHI
IPC: F02D41/06
Filed: 1987-03-24
Abstract: PURPOSE:To dissolve any fuel shortage taking place in response to a drop in a fuel pump capacity by calculating a basic injection time extended in response to a drop in a battery voltage, based on not only an engine temperature but also a battery voltage at an engine start. CONSTITUTION:In running of an engine, an electronic control unit 46 judges whether a starter 56 keeps ON or not firstly, and in case of the starter on, it judges whether an engine rpm detected by a rpm sensor 62 is bigger than a prescribed value (about 500rpm) or not. In case of YES, since the engine is not in starting phase, it calculates the basic fuel amount based on an output of an intake pipe pressure sensor 24 and the rpm sensor 62 as usually. On the other hand, in case of NO, it calculates the basic injection time at the engine start based on the output of a cooling water temperature sensor 50, and also corrects the basic injection time at the engine start, by using a voltage correction coefficient obtained in compliance with the battery voltage at that time and an invalid injection time and, sets such a condition as that time and an invalid injection time and, sets such a condition as extending the injection time on the side of a low temperature and low voltage.

Abstract: PURPOSE:To select the ranking of candidates at a high speed by providing the 1st and 2nd selection storage means, comparing the length of the 2nd data stored in the 2nd selection storage means with the length of the 1st data stored temporarily, and controlling these storage means based on the result of comparison. CONSTITUTION:The 1st data stored temporarily in a 1st storage means 4 of a 2nd selection storage means 2 is added to a comparison means 3 together with the 2nd data stored in a 2nd storage means 5 of the means 2. The means 3 compares the lengths of both data with each other. In this case, the means 3 has a small terminal (s), an equal terminal (e), and a large terminal (g), etc., and outputs the result of comparison to each terminal. When the large data remains, the signals outputted from the terminal (g) are applied to a 1st selection means 6 and a 2nd selection means 7 of the means 2. That is, if the data inputted by the means 5 is larger than the data stored temporarily by the means 4, the former data remains. Thus the means 7 selects the 1st input terminal and applies it to the means 5. Therefore the data stored in the means 5 has no change and the data stored temporarily in the means 4 is selected by the means 6 and outputted. As a result, the ranking of candidates can be set at a high speed.

Title: Switching circuit
Inventor: KONNO MAKOTO
IPC: H03K17/16
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a switching circuit in which a power loss is small and malfunction due to noise can be prevented. SOLUTION: A switching drive signal SD is fed to a terminal 20. A rising of the signal SD is integrated by an integration circuit consisting of resistors 21, 22 and a capacitor 23. A diode 25 is connected to the resistor 22 and a trailing of the signal SD is integrated by an integration circuit consisting of the resistor 21 and the capacitor 23. An integration signal of the signal SD drives a field effect transistor(FET) 24. A capacitor 28 is connected between a drain and a source of the FET 24. The FET 24 is used to control a current flowing to a load 26. The integration circuit reduces a noise level. Since the time constant of the integration circuit consisting of the resistor 21 and the capacitor 23 is short, the power loss of the FET 24 is reduced.  Even when the time constant of the integration circuit is short, since a charging current flows to the capacitor 28 via the load 26, a change in the current slows down, thereby preventing effect due to noise.

Filed: 1987-03-25
Abstract: PURPOSE:To enable switching to be accomplished on light only by a method wherein a laser operating medium is a polymer diffused with an organic pigment compound and the laser exciting light is used as a gate light. CONSTITUTION:An organic pigment compound element 1 is positioned between a receiving mirror 2 and emitting mirror 3. With the incident light 200 landing constantly on an element of this design through the receiving mirror 2, the element adjusts itself in phase to the incident light 200, and yields or fails to yield an output by deciding whether it is to go into a lasing operation. In this case, the exciting light is used also as a gate light 100 for laser operation. That is, the switching element is in an ON state with the gate light 100 coming in and in an OFF state with the same not coming in. The organic pigment compound is pumped by the gate light 100, when phasing is accomplished in response to the incident light 200 for laser amplification. The incident light 200 is amplified before being emitted by the emitting mirror 3, which results in an ON state. Accordingly, a switching function by an optical gate realizes for an IC capable of operation on light alone.

Abstract: PURPOSE:To use effectively the nonsensitive zone of the set value of an original reference when the pressure and flow of a pressure reducing valve are regulated by using a solenoid valve, by giving a dummy set valve and a dummy nonsensitive zone at the time of its pressure rise. CONSTITUTION:At the time of the pressure regulation of a pressure reducing valve, given that the set value of a reference is SP and a dummy set value larger than the set value SP is DSP, pressure rise at the time of pressure rise is conducted by aiming at the dummy set value DPS, and is stopped on the lower side (point P1) of a dummy nonsensitive zone DPSD. When the leak amount of the pressure reducing valve comes to the lower side (point P2) of the nonsensitive zone SPD of the set value SP of the original reference, correction is conducted for the 1st time, and at the time of this correction, pressure rise is again made by aiming at the dummy set value DSP. As a result, correction frequency can be reduced by using effectively the nonsensitive zone SPD of the set value SP of the reference, and the extension of the life of the pressure reducing valve and a solenoid valve becomes possible.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To expose a part which should become a white spot caused by spot light from a correction pixel, to prevent the pixel from being omitted and to prevent the white spot from being recorded on a printed image. SOLUTION: Micromirrors are displaced to an effective reflection state and an ineffective reflection state according to data for driving a mirror. In the effective reflection state, incident light is reflected toward a photosensitive material. When the defective micromirror 50 exists, two exposure actions of the normal exposure action and the auxiliary exposure action are executed. In the case of the normal exposure action, it is executed by driving only the normal micromirror 52 which is not hatched in a state where a projection lens is focused on an object. In the case of the auxiliary exposure action, it is executed by driving only eight correction micromirrors 51 which are not hatched in a state where the focus of the projection lens is slightly deviated.  A cell 53a on which a recording action should be executed by the defective mirror 50 is exposed by the light from the mirrors 51 at the time of the auxiliary exposure action.
