Title: Thin lighter
Inventor: TAKAHASHI AKIO
IPC: F23Q2/28
Filed: 1987-04-28
Abstract: PURPOSE:To provide a battery-powered electric-heater type lighter which excels in portability by an arrangement in which the switch can be turned on and off by the sliding movement of a movable part which can be translationally moved relative to the thin casing. CONSTITUTION:A movable part 9 which can be translationally slided relative to the thin casing 2 is made of an electrically conductive material. Since there is a return spring 10 between the movable part 9 and the casing cover 1 or casing proper 2, the movable part 9 and a switch terminal 11 are normally not in contact with each other. When the movable part 9 is pushed in to slide in the casing 2 against the force of the spring 10, the contact takes place between the movable part 9 and the first switch terminal 11. Then, the button opening 5 and the heater opening 7 in the casing cover 1 are aligned with the button opening 6 and the heater opening 8 in the movable part 9 to expose the push button 16 and the heater wire 13. When the push button 16 is pressed, electric current is caused to flow in the closed circuit of a battery 3, and the heater wire 13 becomes red-hot. The thin battery 3, heater wire 13 and switch terminal 11 are disposed not to overlap in plan view to assure the thin structure.

IPC: B65D5/74
Filed: 1994-04-19
Abstract: PURPOSE:To simplify the manner in which, relating to a device composed integrally of a pouring body and a lid to be fitted molded in one piece, the lid to be fitted is pushed to after being severed and to keep the cap from loss of tightness with which it is fitted even after repetitive removing and replacing of the cap. CONSTITUTION:A pouring body 2 has on its inner side fastening projections for the fitting in a circular arrangement and in the lower part a rim 24 in the shape of a flange. A lid 3 to be fitted has on its outer side fitting projections 31 which correspond to the fastening projections for the fitting and a roof 32 which is flat and whose size is greater at least in part than that of the upper part of the pouring body 2. The inner part at the circular edge of the upper end of the poring body 2 is joined to the outer circular surface of the lid 3, specifically to the part close to its lower end, with the interposition of a thin-walled part. Nothing obstructs when the lid 3, after being severed, is fitted into the pouring body 2 and the lid can be pushed to easily by exerting force evenly thereon. Since the lid 3 is pushed into the inside of the pouring body 2, they fit together with good tightness; this tightness is not lessened and keeps the device free of leakage even after repetitive removing and replacing of the lid.

IPC: H03F3/68
Filed: 1979-08-15
Abstract: PURPOSE:To increase an output while making it easy to distribute and mix electric power signals of a parallel-connected transistor amplifier, by loading a metal partition plate in parallel to the H surface of a rectangular waveguide.

Abstract: PURPOSE: To improve the circularity after the forming, and to reduce the generation of flaws by forming the space between segments of first parallel parts which are opposite to each other in the parallel direction to the center line, and second parallel parts which are opposite to each other in the parallel direction in the circumferential direction. CONSTITUTION: A formed tube 16 is inserted until being abutted on a block 14 in the condition where the outer diameter of a segment 20 is smaller than the inner diameter of the formed tube 16. The inner diameter of the formed tube 16 is expanded to the prescribed size by the segment 20 by driving a hydraulic cylinder 26. The movement in the axial direction of a cone 17 is detected by a linear encoder, etc., and the expansion of the segment 20 can be known from the angle of inclination of abutting parts 17b, 20b. In the adjacent segments 20, parallel parts 20d opposite to the center line of a formed tube 16 are moved in the circumferential direction to expand the outer diameter, and parallel parts 20c are discontinuous in the direction of the center line.  The circularity of the expanded part of the formed tube 16 is improved and the hitting damages of the inner surface are reduced by the parallel parts 20c, 20d arranged alternately.

Abstract: PROBLEM TO BE SOLVED: To provide a device which can initialize the resources synchronously with the operation of a computer device by preparing a means, etc., to produce a reset signal that initializes the resources when the electric power supplied to the resources is detected. SOLUTION: A reset signal generation means is prepared to produce a reset signal that initializes the resources when the electric power supplied to the resources is detected. The reset signal generation hardware 106 of this device can write the data from a computer system main body 101 via a bus line 108. If logical value 1 is written into the hardware 106, a reset signal line 111, etc., are activated and the resources are reset within a docking station. Then logical value 0 is written into the hardware 106 after a time necessary for the initialization. In such a case, the line 111 is inactivated and the reset state of the resources is canceled within the docking station. Thus, the initialization of the resources is over.

Title: Fault prevention circuit for flyback transformer
Inventor: SAEKI TAKAHIRO
IPC: H01F38/42
Filed: 1990-04-18
Abstract: PURPOSE:To prevent a user's shock fault (US fault) by stopping the operation of the flyback transformer when an abnormal heat is detected based on a difference between a power fed to the flyback transformer (FBT) and a high voltage output power of the PBT and on the result of detection of a high voltage output current. CONSTITUTION:When the FBT 30 reaches an abnormal heating state due to its internal heat and a voltage VBH exceeds a reference voltage Br1 corresponding to a fault detection level, an output of a comparator 4 changes from a low level to a high level. when the output of the comparator 4 reaches a high level, an output signal is inputted to a flip-flop 5 via an OR gate 6 and an output signal VQ of the flip-flop 5 reaches a high level and the signal VQ turns off a switch circuit 10 to interrupt the supply of B power supply to the FBT. Thus, the occurrence of the US fault is prevented.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To intermittently perform the discharging of a molten substance by generating heat by a slag discharging device itself, and transmitting heat to the molten substance which has solidified and closed a slag discharging port by the transmission of the heat. SOLUTION: This slag discharging device 3 comprises a cylindrical heating material having a slag discharging port 3c, a protective material 3e on the outside of the cylindrical heating material 3d, and a slag discharging pipe 3b and an induction heating coil 3a on the outside of the protective material 3e. When AC is turned on the induction heating coil 3a, an AC magnetic field is applied to a molten substance which closes the slag discharging port 3c, the heating material 3d, and the protective material 3e. Even when the molten substance is a slag, an eddy current is generated to the heating material 3d by an electromagnetic induction, and the solidified molten substance gradually melts by Joule heat. A slag discharge starts accompanying the melting. When the slag discharging needs to be stopped, power is turned off, or the electric current is regulated.  By this constitution, the molten substance is gradually cooled from the wall surface of the slag discharging port 3c, a solidified molten substance grows and closes the slag discharging port 3c again, and the slag discharging is stopped.

Abstract: PURPOSE: To obtain the heat-sensitive semiconductor swith having arbitrary switching temperature of the switch.  
     CONSTITUTION: The temperature of a heat block 4 is set at desired switching temperature while measuring the temperature of the heat block 4 by a thermometer 51. A semiconductor element 1 is set in off state at this time. A sandblast 7 is operated in this state to cut it to reduce the width W of a gate resistance RGA so as to enhance the resistance valuve. As the resistance value of the gate resistance RGA is increased, the switching temperature of the element 1 falls to finally reach desired preset switching temperature. The element 1 becomes on state at this time, and the state is detected by a voltmeter 63. The sandblast 7 is stopped at this time.
