Title: Synchronous parallel-in confirming device for brushless synchronous motor
Inventor: KOGURE FUMIO
IPC: H02P1/50
Filed: 1986-02-17
Abstract: PURPOSE:To permit detection of synchronous parallel-in on the stator side by a simple constitution by transmitting an output of an automatic synchronous parallel-in device through a light-emitting diode to a receptor on the stator side. CONSTITUTION:A rotary rectifier 2 provided at the rotating part 1 of a brushless synchronous motor is composed of a thyristor 3 and a rectifier 4 so that a synchronous parallel-in may be automatically conducted within the rotating part and a gate signal of the thyristor 3 is outputted from an automatic synchronous parallel in circuit 5. This gate signal is detected by a detector circuit 6 and light is emitted by passage of an electric current through the light-emitting diode 7. The light emitted from the light-emitting diode 7 is received by a receptor 8 installed at a right angle to the axis and provided on the stator side on the same cross section. In this manner, the timing of synchronous parallel-in can be easily detected on the stator side.

Title: Ignition timing control device for internal combustion engine
Inventor: MORITA TATSURO
IPC: F02P5/153
Filed: 1986-02-14
Abstract: PURPOSE:To prevent the occurrence of knocking, by a method wherein, when a cylinder is transferred to a knock inducing condition attendant with a rapid decrease in rotation of an engine, an ignition timing is rapidly delayed by the use of a learning value in a corresponding region. CONSTITUTION:In a control circuit 19, the memory regions of a rewritable memory are respectively allotted to one operation region or more. From continuance of a rapid change in rotation of an engine, a condition under which knocking is apt to occur is decided, and when a cylinder corresponds to the condition, from a memory allotted to the operation region, a memory value is immediately read as the delay angle correction amount of all cylinders to momentarily delay an ignition timing. This delay prevents the occurrence of knocking. Meanwhile, during a given period after elapse of a knock inducing condition or during a time in which an operation region is changed, a current delay angle correction amount is learnt, the learning value is renewed and stored, and serves to control prevention of the occurrence of subsequent knocking as data precision is improved.

IPC: F16H63/46
Filed: 1984-02-23
Abstract: PURPOSE:To prevent the generation of advance shock by controlling the working-oil pressure of a friction element for advance so that the number of engine revolution is kept at a prescribed value in the engine idling state when a car is in stop. CONSTITUTION:A drain port 5a is formed in a working-oil hydraulic circuit 5 for feeding the working-oil pressure to a friction element 2 for advance, and a plunger 17a is brought into contact with said drain port 5a. In the engine idling state in stop, the working-oil pressure of the friction element 2 for advance is controlled by the plunger 17a so that the number of revolution of an engine is kept at a prescribed value. Therefore, time lag is not generated in the starting- up of the working-oil pressure on advance, and the generation of the advance shock due to engine idling can be prevented.

Abstract: PURPOSE: To make it possible to detect the positions of ICs, including ICs with missing lead terminals, with accuracy, by calculating lead bend for each group of lead terminals on respective side to select a lead terminal with a less bend, and detecting the central position of each group of the lead terminals on respective sides according to the position data on the selected lead terminals. CONSTITUTION: Regression straight lines L1, L2 indicating the correlation between lead terminal numbers and the coordinates of the detected positions of the tips of the lead terminals, are drawn. Lead bends are calculated from the regression straight lines, and regression straight lines L1', L2' are drawn again based on data indicating less lead bends, that is, some data at short distances from the regression straight lines L1, L2. The coordinates for the numbers of the central lead terminals in upper lead terminal groups are calculated from the regression straight lines L1', L2', and the results of the calculations are stored as the coordinates of the central positions of the upper lead terminal groups. Then a microcomputer 6 detects the central position of the group of the lead terminals on each side of IC 100, and calculates the central position and inclination of the IC.  It then creates correcting data and outputs it to a position control circuit 7.
