Title: Welding method
Inventor: NOHARA KAZUHIRO
IPC: B23K26/21
Filed: 1990-10-22
Abstract: PURPOSE:To easily weld even a part in which a welding torch cannot be inserted by heating the opposite surface by using a laser beam having high energy density. CONSTITUTION:Since the laser beam having high energy density is used as a heat source used for welding, when the rear of the surface where a sheet metal 1 and the other sheet metal 2 are brought into contact with each other is irradiated with the laser beam, penetration of the sheet metals is deep and accordingly, the surface of the sheet metals, namely, even a contact part between the sheet metal 1 and the other sheet metal 2 is molten and the sheet metal 1 and the other sheet metal 2 are integrated into one body and welded together. Accordingly, even the part in which the welding torch cannot be inserted can be easily welded by heating the opposite surface.

Filed: 1988-11-11
Abstract: PURPOSE:To eliminate speckles produced on the observation surface of an observation device so as to make observation with always excellent brightness by performing the observation by stopping a scanning light wheel at a desired point and inserting a removable diffusing plate into an observation system. CONSTITUTION:The rotary polygon mirror 13 of a scanning system is stopped from a rotating state through a stopping means 13a and a scanning light wheel which illuminates a wafer 2 is stopped at a desired position. The reflected light from the wafer 2 produced when the wafer 2 is irradiated with the scanning light of the light wheel is received by means of a photoelectric converting section 34 through beam splitters 17 and 61 and, at the same time, made incident on an observation system and visually observed through the erector 52 of a diffusing plate which can be removed by means of an observation system driving means 52a. When the observations are made, variation in brightness is reduced and observations can be always made with excellent brightness, since the occurrence of speckles is reduced by means of the erector 52.

Title: Manufacture of fe-ni alloy magnetic film
Inventor: HONDA NAOKI
IPC: C23C14/34
Filed: 1986-12-01
Abstract: PURPOSE:To inhibit an Fe-Ni alloy magnetic film from increasing resistance to magnetic force by means of a simple method before the film is formed by sputtering within an atmosphere in which impurity gas of water of oxygen exists, by intro ducing nitrogen into the sputtering atmosphere. CONSTITUTION:In order to form an Fe-Ni alloy magnetic film on a polymeric substrate by performing a sputtering process within an atmosphere containing water and/or oxygen at a maximum deposition rate of 8.3X10<-10> Torr (Angstrom /min), nitrogen is introduced into the sputtering atmosphere under a pressure 1/5-5 times higher than the pressure of said water and/or oxygen. According to this method, even if a high pressure of impurity gas in water or oxygen exists within the sputtering atmosphere, an Fe-Ni alloy magnetic film having a low resistance to magnetic force as desired can be manufactured easily without performing bias sputtering or lowering a back ground pressure.

Filed: 1994-11-21
Abstract: PURPOSE: To improve thickness accuracy in a region where variation of rolling load is larger and to improve rolling yield by correcting the correction factor of screw-down location in accordance with the absolute value of variation in rolling load. CONSTITUTION: A 1st screw-down location correcting amount and a 2nd screw-down location recorrecting amount are inputted to an adder 100 and the sum of them is outputted to a screw-down location controller 6. In the screw-down location controller 6, by correcting the screw-down location by the value of the sum of the 1st screw-down location correcting amount which is calculated with a 1st arithmetic unit 20 for screw- down location correcting amount and the 2nd screw-down location correcting amount which is calculated with a 2nd arithmetic unit 30 for screw-down location correcting amount, the thickness of a rolled stock 1 is controlled. Moreover, the thickness of the rolled stock 1 is controlled and simultaneously the corrected screw-down location is also outputted to the 2nd arithmetic unit 30 for screw-down location correcting amount with the screw-down location controller 6.  In this way, the variation of the thickness on the outlet side is controlled without rapidly changing the shape of the rolled stock and, further, highly accurate thickness control is attained, so that the rolled stock having good accuracy in thickness is stably obtained.

Filed: 1991-10-31
Abstract: PURPOSE:To prevent destruction of a terminal equipment or a transceiver or communication disable state due to improper selection of pair twisted lines and a connection object by providing a synchronization detection circuit to a hub transmission circuit. CONSTITUTION:In the twisted pair line concentrator for a local area network implementing the communication control for the IEEE802.3-TYPE-10BASE-T or equivalent, a hub 4 is provided with a transmission circuit collision detection circuit 18. The circuit 18 monitors signal inputted to a transmission line 14 or a signal inputted to a pulse transformer 16 to monitor the presence or absence of external data synchronously with the transmission data. When the pair twisted line 5, or a connection object terminal equipment 6 or the hub 4 is connected in error, the pulse transformer 16 detects a signal or other than its own port, and a changeover device 17 selects the state from transmission- transmission line into the state of transmission-reception line. Thus, even when the connection is made in error, the connection is automatically reversed and a normal link state is surely obtained.

Title: Theft preventing device
Inventor: MUTO EIJI
IPC: B60R25/24
Filed: 1994-10-28
Abstract: PURPOSE: To prevent the delay of engine start due to a judgment made by an immobilizer. CONSTITUTION: When a key 2 is operated, a starter motor 9 is energized. At the same time, the action of an engine control part 16a and a theft detecting part is started. Afterwards, if the complete explosion of an engine is detected by a complete explosion detecting part 16c, whether there is an authorization code from the theft detecting part 10 is judged by an immobility judging part 16b. When there is no authorization signal, the immobility judging part 16b outputs a stop command to the engine control part 16a. The engine is thus started immediately after the key 2 is turned so as to prevent the delay of engine start due to a judgment made by an immobilizer.
