Patent JP-H0541474-A (JP)
Title: Semiconductor device
Inventor: KOBAYASHI SHINICHI
IPC: H01L23/62
Filed: 1991-08-06
Abstract: PURPOSE:To shunt an electric current flowing to an intermediate terminal conductor to a connection conductor at the time of turning off so as to suppress the generation of a surge voltage by connecting the fixed electrode conductors of two semiconductor elements to each other with the intermediate terminal conductor and the intermediate terminal conductor in parallel with the connection conductor having a smaller floating inductance and larger resistance value than the intermediate terminal conductor has. CONSTITUTION:A main current is made to flow from the emitter of a transistor 21 to the collector of another transistor 22 and a connection conductor 26 having a floating inductance l' smaller than the floating inductance bE1 of a terminal conductor 25 led out to a terminal E1C2 and a large DC resistance is provided in parallel with the conductor 25. Therefore, a steady-state current flows through the conductor 25 having a smaller resistance value, but, when the transistor 21 is turned off and the current starts to decrease, the AC inductance of the conductor 25 becomes higher than that of the conductor 26 and the current is shunted to the conductor 26, because the floating induction lE1 of the conductor 25 is larger than that l' of the conductor 26. Consequently, the surge voltage applied across this element drops.
Patent JP-H0359903-A (JP)
Title: Lighting fixture
Inventor: MARUYAMA TATSUO
IPC: F21V7/22
Filed: 1989-07-28
Abstract: PURPOSE:To enhance the safety of the lighting fixture without thermally damaging a subject to be irradiated by causing a reflector disposed optically opposite to a light source to diffuse and reflect at least infrared range, and also providing a base which has a reflecting face having a smooth surface, and forming a wavelength selecting reflecting film from optical multilayer films on the surface of the reflecting face of the base. CONSTITUTION:A reflector 5 disposed optically opposite to a light source 6 diffuses and reflects at least infrared range and also has a base 10 which has a reflecting face of a smooth surface, and a wavelength selecting reflecting film 16 is formed from optical multilayer films on the surface of the reflecting face of the base 10. Visible light incident on the reflector from the light source is selectively reflected by the wavelength selecting reflecting film 16 and is converged and caused to go out, while infrared rays and visible light which have not been reflected by the wavelength selecting reflecting film 16 are reflected irregularly and caused to go out as diffused light. The base does not therefore absorb light in the infrared range nor allow any light to transmit through it. The reflector is not therefore heated and the temperature rise at a ceiling surface, etc., on which the lighting fixture is attached is low, and the safety of the lighting fixture is enhanced and the fixture will not heat a subject to be irradiated.
Patent JP-S6438937-A (JP)
Title: Vacuum interrupter
Inventor: TORITSUKA HIDEAKI
IPC: H01H33/66
Filed: 1987-08-04
Abstract: PURPOSE:To prevent a rise in temperature due to local concentration of arc energy on a surface of a main electrode and to improve interruption performance by igniting an arc on a spiral electrode and next by moving the arc immediately to the surface of the main electrode and dispersing it. CONSTITUTION:When a contact surface of a spiral electrode 31 is finally detached, ignition occurs and an arc is magnetically driven toward a peripheral part by electromagnetic force generated by the spiral electrode, so that the arc is made to pass through a ring-shaped high resistance part 29 immediately and to be transmitted to a main electrode 23. When an electrode opening operation of a vacuum interrupter is performed at the near peak time of an arc current, the arc becomes columnar one with high current density, and it becomes very high in its magnetic driving force, and it is transmitted to the main electrode immediately after its ignition. When the arc is once transmitted, an axial magnetic field is generated by a current flowing via a coil part 23b of the main electrode to a short-circuit member 27. Accordingly the arc transmitted to the main electrode becomes a diffusion one by the function of the axial magnetic field to be dispersed uniformly on the surface of the main electrode, so that local heating of the surface of the main electrode can be prevented.
