Title: Controller for fuel injection timing of diesel engine
Inventor: SUZUKI YUTAKA
IPC: F02D41/40
Filed: 1983-03-25
Abstract: PURPOSE:To reduce the influence of a secular change etc., by controlling the fuel injection timing of a Diesel engine so that its ignition timing found out by an ignition detector becomes coincident with an aimed timing. CONSTITUTION:An aimed ignition timing is calculated depending on the output of a running condition detector 1. The actual ignition timing is calculated from the outputs of a reference position detector for the crank angle and an ignition detector for the actual ignition. An injection timing control means is driven depending on the difference between the aimed ignition timing and the actual ignition timing. According to this constitution, the influence of the dispersion in the performance of a fuel injection line, a secular change, a fuel replacement, etc. is reduced.

Title: Bonder
IPC: H01L21/60
Filed: 1992-03-10
Abstract: PURPOSE:To heat a bonding with a good response and prevent the breakage of a wiring, by applying a high-frequency current to a coil and generating an AC magnetic field and.performing an induction heating. CONSTITUTION:Inner leads 2 formed on a film carrier 1 are connected to electrode pads 4 of semiconductor chips 3. In this case, when operating a high-frequency power source 17 and applying the high-frequency power source 17 to a coil 16, an AC magnetic field is generated around a bonding tool 15. By this, an eddy current flows within the bonding tool 15 and an eddy current loss occurs. Also, since the bonding tool 15 is made of a magnetic substance, a hysteresis loss occurs. The hysteresis loss is converted into a heat energy and the bonding tool 15 is heated with a good response. Thus, a good bonding can be performed even if a soldering connection is used. Further, since the bonding tool 15 itself is not heated, a wiring is eliminated and the break of the wiring due to a vertical motion does not occur, and there is no fear of failure.

Title: Input circuit
Inventor: TAKAYAMA SHIGERU
IPC: H03K5/1252
Filed: 1989-03-03
Abstract: PURPOSE:To prevent malfunction of an input circuit due to noise and to improve the noise eliminating capability by detecting the occurrence of a change in an input signal while a sampling clock phi is inactive and inhibiting the production of an output signal of an input circuit when an input signal is changed. CONSTITUTION:After an H level of an input signal IN3 is latched at the trailing edge of the clock phi for a period of T11, when the input signal IN3 is changed to an L level again when the clock phi is at an L level, an output of an AND circuit 11 goes to an H level for the period of T11. Since an output of the AND circuit 11 connects to a set input of an RS flip-flop 12, the RS flip-flop 12, the RS flip-flop 12 is set for the period of T11, and an inverse of Q output D8 goes to an L level. Thus, the inverse of Q output D8 of the RS flip-flop 12 goes to an L level for a period of T11-T13 and malfunction due to noise generated synchronously with the trailing of the clock does not take place.
