Title: Control device for engine
Inventor: SHIRAKAWA AKIRA
IPC: F02B37/00
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To restrain the lowering of a catalyst temperature under the operation condition in which an exhaust temperature is lowered. SOLUTION: An engine 1 has a catalyst 5 whose exhaust emission control efficiency is depended on an exhaust temperature and can control the exhaust flow rate passing the catalyst 5 by adjusting the opening of the nozzle of a variable capacity supercharger 3 provide on the upper stream of the catalyst 5. A controller 20 judges the operation condition in which the exhaust temperature is lowered and issues an order to a step motor 31 for driving the nozzle of the variable capacity supercharger 3 so as to reduce the exhaust flow rate passing the catalyst 5 under the operation condition in which the exhaust temperature is lowered. Thereby, the lowering of the catalyst temperature of the catalyst 5 is restrained and the exhaust emission control efficiency can be kept highly.

Title: Semiconductor manufacturing device
Inventor: TANIGUCHI JUN
IPC: H01L21/60
Filed: 1991-10-07
Abstract: PURPOSE:To cut down the required time for wire bonding step as well as the manufacturing cost of semiconductor device by a method wherein, in order to connect an electrode pad to a relay point, the bonding step of multiple wires is performed at one time using a capillary wherein multiple holes are made in-parallel. CONSTITUTION:Wires 3 are passed through respective multiple holes 2 juxtaposed in a capillary 1; the wire 3 ends are made spherical by electric discharge; another capillary 2 is moved to junction an electrode pad 5 with a relay point 6 by pressurization and ultrasonic vibration; and then the wires 3 are cut down. Thus, the bonding step of multiple wires can be performed at one time by equalizing the pitch of the holes 2 of the capillary 1 to that of the electrode pad 5. Furthermore, the dispersion in the loop shape caused by the dispersion in the capillary locus control due to the repetition reproducibility precision of a wire-bonding device can be diminished.

Abstract: PROBLEM TO BE SOLVED: To perform correct tracking control without lowering a light quantity by using a differential push-pull signal of a fixed spot and generating a tracking error signal canceling an offset component. SOLUTION: Although an intensity distribution of reflection light on a photodetector 27-2 becomes equal rate in upper/lower areas when the spot 31 traces a normal position, when the spot 31 traces the shifted position shown by a solid line, in the intensity distribution of the reflection light on the photodetector 27-2, respectively different area sides become stronger, and a radial push-pull signal RPP becomes smaller than zero on X1, and becomes larger than zero on X2 when the position of the spot 31 exists on the X1 on a clock mark and when it exists on the X2 on a data area. Even when the reflection optical axis of the photodetector 27-2 is shifted due to a tilt, etc., of a disk, and the offset occur on respective RPPs, these offset amounts become the same, and the offset in the tracking error signal is canceled.
