Title: Method for cutting off cubic system boron nitride sintered body
Inventor: OKAMOTO TETSUYA
IPC: B23K26/38
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To cut off a sintered body in high efficiency by irradiating the surface of cubic system boron nitride sintered body with laser beam to form a groove which does not reach the outer peripheral part of the sintered body, applying outer force and cutting off along the groove. SOLUTION: The groove is formed by irradiating the surface of the sintered body with the laser beam. The depth of the groove is desirable to be 1/10-1/2 of the thickness of the sintered body. In the case of the depth of <1/10 of the thickness, at the time of cutting off by applying the outer force, it happens to develop the crack because of the necessity of large force. In the case of forming the groove having the depth exceeding 1/2 of the thickness, it happens to develop the crack even at out of the thickness direction. It is necessary that the groove is not extended to the outer peripheral part. In the case of extending the groove to the outer peripheral part, the crack is easily developed. The crack is difficult to develop by keeping the groove apart from the outer peripheral part by >=0.3mm.  Since the beam diameter is desirable to be smaller because of the reduction of the cutting-off thickness, it is desirable to use a YAG laser beam.

Inventor: SANGO TORU
IPC: G01V9/00
Filed: 1989-10-20
Abstract: PURPOSE:To preclude trouble occurrence due to in-piping residual water at the time of product shipment by comparing temperature profiles of a piping member at respective positions where it is evident that water stays and no water stays because of the structure. CONSTITUTION:Thermocouples 1 and 2 are brought into contact with the external surfaces of a position A where water stays judging from a structure figure and a position B where no water stays. Then heating air is sent continuously to water drained piping and the external surface temperature at the positions A and B are measured at the same time. Then while the measured value at the position A is much less than that at the position B, it is decided that remaining water 4 is present in the piping at the position A and it is also decided that the residual water 4 is eliminated when the remarkable difference is eliminated. Consequently, the residual water in the piping can easily and securely be checked.

Title: Excimer laser device
Inventor: FUKAYA KUNIAKI
IPC: H01S3/03
Filed: 1986-11-18
Abstract: PURPOSE:To aim to prolong the service life of a thyratron by a method wherein an excimer laser discharge tube, preionization pin, thyratron element, and resistance serially connected to the thyratron element are provided, and a secondary circuit containing the discharge tube is in resistance approximately similar to a primary circuit containing the thyratron element. CONSTITUTION:Upon turning-on of a thyratron element 21, a peaking capacitor C22 is charged to a prescribed level, a preionization pin 22 experiences dielectric breakdown, and ultraviolet rays, etc., are generated. Consequently, voltage rises across the two ends of a discharge tube 23 to trigger off a glow discharge between the two electrodes, for the generation of an ultraviolet laser beam, when a back current will flow in the thyratron element 21 whose value is kept low by a resistance 25. The value of an R25 is so set that a secondary circuit resistance value R22+R32+R23 may be approximately equal to a primary circuit resistance value R25+R31. With the device being designed as such, a current back to the primary circuit will be reduced and the service life of the thyratron element 21 will be prolonged, without a reduction in the laser oscillator efficiency.

Title: Ignition timing controller of internal combustion engine
Inventor: HONDA OSAMU
IPC: F02P5/10
Filed: 1984-12-28
Abstract: PURPOSE:To reduce the number of parts by sensing variation of a potential between a conventional intake pressure sensing means and an indicating means in the form of an engine load signal and performing ignition timing control in accordance with said signal. CONSTITUTION:A control means 6 receives signals (l) to (m) relating to engine operating conditions, processes them and outputs an ignition timing control signal P. One terminal of secondary electric path 24 the other terminal of which is connected to said means 6 is connected to a wire 26 at a point A between a pressure switch 8 which senses a pressure of an intake manifold 4 and a turbo indicator lamp 16. Since the pressure switch 8 is kept off at a low load time, a potential at the point A is approximately the same as that of a battery 22. At a high load time, a supercharging pressure acts to turn the pressure switch 8 on so that the potential at the point A becomes an earth potential. Such variation in potential at the point A input to the control means 6 in the form of an engine load signal to control ignition timing in accordance with load. Since an extra engine load sensing means need not be mounted, the number of parts can be reduced.

Title: Elevator door control device
Inventor: KODERA TOSHIYUKI
IPC: B66B13/14
Filed: 1989-10-23
Abstract: PURPOSE:To stop the racing of a motor when a door is left in the forcibly opened state and the motor is in the racing state by providing a reset circuit for detecting the output of a rotating speed signal generating means so as to reset the action of an output denying circuit. CONSTITUTION:In case dirt clogging or the like is generated in the totally closed position of a door, the door is totally closed once by its closing inertia, and then a current is reduced, so that the door is returned surpassing door position detecting switches 8, 9. A limiter circuit 7 thereby stops its action, and the door is judged to be force-opened in a control circuit. The torque of a motor 1 is therefore increased, resulting in the slip of a belt and the racing of the motor 1. As the output of a rectifier circuit 3 is applied to a reset circuit 12, the output of an A.C. type generator 2 becomes large and thereby the output of the circuit 3 becomes large, and when this output exceeds the threshold value determined by a Zener diode 12b, the circuit 12 generates output for resetting the action of an output denying circuit 10, thus stopping the racing of the motor 1.
