Title: Optical scanner
Inventor: KANEKO SHIYUUZOU
IPC: G02B26/12
Filed: 1984-07-11
Abstract: PURPOSE:To reduce the size of the device or increase screen size and recording density and to improve additional functions of editing of an image, etc., by constituting the optical scanner by using polygon mirror which rotate through the same shaft and scanning direction converting means. CONSTITUTION:Light beams from semiconductor lasers 3a-3c which are scanned at right angles to the direction of the shaft through the polygon mirrors 5a-5c which rotate through the same shaft are passed through scanning direction converting means 16a-16c to change their directions almost to the shaft direction, so that they are written through f.Q lenses 7a-7c to write widths la-lc. Consequently, when three polygon mirrors having a rotational frequency (f) are used, the deflection width of the beams is one third as large as before, so the optical length is reduced merely to on third; when a video signal of the same frequency as before is used, write density is increased three times.

Abstract: PURPOSE:To keep the inside of a reaction vessel in a constant dry atmosphere, and remarkably reduce epitaxial crystal defect, by constituting the aperture part of a reaction vessel so as to be able to jet dry inert gas toward the outside of the reaction vessel. CONSTITUTION:After a necessary film forming process is finished, reaction gas supply is interrupted, and the following are started; purging with dry N2 gas from a sealing plate 4, purging from an N2 gas jetting equipment 10, and purging with dry N2 gas from the jet nozzle of a gas ring 5 operated by a switching valve 11. After the ascending of a susceptor 3, the aperture part of a reaction vessel 1 is sealed by dry N2 gas from a gas jetting equipment 10 installed on the gas ring 5. The inside of the vessel 1 is kept in a constant dry atmosphere by jetting dry N2 gas into the inside of the vessel 1 from the gas ring 5. Hence the attaching water content amount and the formation material due to reaction gas residue can be reduced, so that very excellent epitaxial growth is realized and the reduction of particles is enabled.

Title: Device control system
Inventor: TAKAYANAGI TOSHIHIRO
IPC: G06F11/30
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To prevent an electric motor or the like from being destructed by preventing the occurrence of operation abnormality in a CPU due to the absence of a necessary memory in the device control system. SOLUTION: A cod 'FFFFH' read out by an access to a non-existing ROM is interpreted as a software interruption by the CPU and an access to an address 'FFFF1CH' in a vector table is generated. When the error processing is started, accesses to the non-existing ROM are frequently generated and the software interruption is repeated. Thereby enormous stack data are stacked and abnormal, data are written in a port. However an address decoder 98 immediately repeats the reset of a motor port 94 in accordance with the frequent accesses of the CPU to the address 'FFFF1CH', so that a main motor 84 and its relative mechanisms can be prevented from being destructed due to excess load.

Title: Electric floor heater
Inventor: KOJIMA SUZUO
IPC: F24D13/02
Filed: 1978-11-21
Abstract: PURPOSE: To assure the current breaking to the flat type heater when abnormal rising of the temperature occurs by installing a leak breaker with trip coil to be energized with the temperature control switch, a temperature detector of the flat type heater and its temperature control apparatus.  
     CONSTITUTION: When the temperature of the flat type heater 3 is abnormally risen and reaches the switching temperature, the temperature control switch 6 is turned on, whereby the trip coil of the leak breaker 2 is excited. Then the leak breaker 2 is actuated and the AC voltage impressed to the flat type 3 is broken. Thus the temperature of the flat type 3 lowers and the danger of fires due to abnormal overheat is prevented. When the leak breaker is once actuated, power is not made ON unless the circuit is made by manual operation even if the temperature of the heater is fallen. Thus the safety is improved.
