Title: Manufacture of transistor
Inventor: YAMAHATA SHIYOUJI
IPC: H01L29/20
Filed: 1986-06-06
Abstract: PURPOSE:To insulate a base or a gate electrode and source and drain electrodes, and to contrive to shorten the distances between the respective electrodes by a method wherein a metal for electrode on insulating films on both the sides of the base or the gate electrode part is removed selectively using oblique ion beam milling. CONSTITUTION:The incident angle (alpha) of an ion beam is the angle formed between the surface of a film and the ion beam, and when the angle (alpha) to a vertical wall satisfies the condition alpha deg.>45 deg. at the case of Au, the metal deposited on the vertical wall is etched at a more larger etching rate, and as a result, the metal on the SiO2 film of the side wall is etched selectively. Therefore the AuGe/Ni/Ti/Au metal 15 for an emitter and a collector electrode is evaporated to the whole surface, and after then, by removing selectively the metal 15 for the emitter and the collector electrodes evaporated on the SiO2 film of the side wall according to oblique ion beam milling, electrode separation between the base electrode is attained, and the emitter and the collector electrodes are formed. Accordingly, the distance between the emitter and the base electrodes and the distance between the base and the collector electrodes can be shortened sharply as compared with a laterally bipolar transistor.

Title: Multi-stage collector type traveling wave tube
Inventor: KAGEYAMA TAKAO
IPC: H01J23/087
Filed: 1981-08-21
Abstract: PURPOSE:To saturate magnetism in a pole piece and obtain a strong focusing magnetic field in a collector without restricting cooling process by making the thickness of the pole piece that is arranged at an end nearest to the collector thinner than that of other pole pieces. CONSTITUTION:The thickness of a pole piece 9 nearest to the first collector 10 is made thin up to approximately a half of the remaining pole piece 8 . Thus, magnetic saturation takes place in the pole piece 9 and leaked magnetism generates an intense inverse magnetic field at the inner part of the first collector 10. This intense inverse magnetic field prevents the sudden diffusion of an electron beam that flows in the collector, guides the electron beam up to the lower potential second collector 11, and improves the overall efficiency. Suppose that the thickness of the pole piece 8 is t1 and that of the pole piece 9 is t2, a condition of 0.5 t1>=t2 is required to generate magnetic saturation effectively.

Abstract: PURPOSE: To provide a pulse arc welding machine which eliminates the production of spatters during arc firing by applying high frequency voltage in superposition to the pulse voltage applied between a consumable electrode and base metals to generate high frequency electric discharge thereby inducing pulse arc electric current.  
     CONSTITUTION: First, switches for a high frequency power source 14, a pulse  power source 1 and a power source of the motor in a wire feeder 5 are turned on  to apply high frequency voltage between an electrode 4a and base metals 6. High  frequency electric discharge is induced between the electrode 4a and the base metals  6 via the cable 4 on torch 3 side, a high frequency reactor 16 and a high frequency  bypass capacitor 15, whereby high frequency current is flowed therebetween. During  this time, the reactor 16 provides a high impedance with respect to high frequencies  and the capacitor 15a low impedance with respect to high frequencies and therefore  the high frequency voltage is applied mostly across the reactor 16. Hence, the high frequency voltage applied upon the power source 1 and the device 5 is attenjated to low voltage. As a result, the electric power source for supplying arc maintaining current is saved and the production of spatters during firing is eliminated.
