Title: Ignition control device for internal combustion engine
Inventor: NAGANO MASAMI
IPC: F02P5/15
Filed: 1986-05-23
Abstract: PURPOSE:To prevent surging in normal and decelerative operation in low-speed range by controlling ignition timing on the basis of the change amount of the revolving speed and its direction, and altering the correction amount and the correction frequency in specific conditions. CONSTITUTION:Reference signal fro ignition timing and signals of revolving speed etc. are given to a control unit 15 from a dist. 16. The unit 15 reads the standard ignition timing from a memory map, the gear position signal and actual revolving speed. In case the change in the revolving speed per specific period of time exceeds a certain value, judgement is made whether the gearing is in first or second position to serve for determination of the ignition timing corrective amount and the correction frequency on the basis of the judgement result. The modified ignition timing is determined by adding or subtracting the correction amount to/from the standard ignition timing according to information if the change in the revolving speed is positive or negative, and the result is accommodated in a certain address together with the standard ignition timing. Actual ignition timing is controlled by sending this signal to a power transistor of an ignition coil 17. This suppresses surging effectively.

Title: Manufacture of samarium-iron-nitrogen magnet powder
Inventor: KOJIMA SEIJI
IPC: H01F1/059
Filed: 1995-05-16
Abstract: PURPOSE: To reduce the occurrence of oxidation and defectiveness in magnet material and make it possible to pulverize it in relatively short time, by using a ball mill with the portion of its container to be brought into contact with power made of ceramic or glass and its ball made of ceramic. CONSTITUTION: An alloy powder mainly composed of a R2 T17 Nx phase (where, R is an element obtained by substituting a rare earth element for Sm or part of Sm; T is an element obtained by substituting a metal other than Fe for Fe or part of Fe; x=2.0-3.5) is pulverized in a solvent containing an unsaturated fatty acid and/or its glyceride. For the pulverization, a ball mill is used; the portion of its container to be brought into contact with powder is made of ceramic or glass, and its ball is made of ceramic. Use of this ball mill prevents magnet powder from sticking to the powder-contact portion of the container of the mill or the surface of the ball, and makes it possible to pulverize material in a short time. It also reduces the occurrence of oxidation and defectiveness in magnet material.

Title: Combustion device
Inventor: MASAI TADAHISA
IPC: F23C5/08
Filed: 1982-07-08
Abstract: PURPOSE:To reduce the concentration of NOx without increasing the amount of soot contained in exhaust gas, by forming subsidiary fuel injection ports directed toward the region between burner rows where the density of nitrogen oxides is hight in a combustion device having a plurality of burners including main fuel injection ports disposed in a plurality of stages and rows. CONSTITUTION:Although subsidiary injection ports 8 can be formed at either of an upper or lower portion between burner rows 2, 3 and 4, it is preferable to dispose them at a lower position. A mixture consisting of fuel and a small amount of air is ejected from the subsidiary injection ports 8 and produces flames 15, 16 involving reducing radicals while lowering the temperature near the ports 8. At the same time, NOx contained in the combustion gas flowing upward between the burner rows is reduced by the flames 15, 16 through contact therewith, so that the density of NOx is lowered. Although the amount of unburnt substances including reducing radicals is increased, they are burnt further by air supplied from air ports formed on the front side 5 and the rear side 6, so that the amount of soot is not increased.

Title: Automatic registering exposure system
Inventor: IMAMURA TOORU
IPC: H01L21/027
Filed: 1978-09-25
Abstract: PURPOSE: To enable target pattern to be made in almost all the processes for manufacturing semiconductors by detecting interferring light from the coming on two light paths due to the variation in thickness of insulating film.  
     CONSTITUTION: The light having come out of a light source 8 is linearly polarized by passing through a polarizing plate 9. When applied to a Normarsky prism 14 after reflected by a half-mirror 13, this linear polalization is separated into two light whose oscillation planes are orthogonal with each other. The light is projected to a target on the surface of a semiconductor substrate 17 after passing through a lens 15 and a photo-mask 16. Since the target has a step portion formed of Si oxide film, the two light cause a difference in phase due to that between light paths after reflection. Further, the two light are combined into one light by the prism 14, generates interferring light when passing a polarizing plate 12, and reaches a photoelectric conversion element 10. The element 10 can be informed of the position of the target by detecting the interference of the interferring light. Thereby, detection becomes possible at the target pattern made only of the step portion of Si film without any Si step portion.
