Title: Manufacture of semiconductor element
Inventor: HONMA TOSHIHIRO
IPC: H01L21/3205
Filed: 1990-04-12
Abstract: PURPOSE:To form a gate oxide film in a uniform thickness on the entire surface of a gate electrode by obliquely implanting impurities to a polysilicon gate electrode by an ion implanting method while rotating the matter to be implanted. CONSTITUTION:In a manufacturing method of a laminated polysilicon transistor, a gate electrode 23 is formed of polysilicon, and impurities are implanted to the electrode 23 by a rotary oblique ion implanting method. That is, when the impurities are implanted to the electrode 23 by this method, resultantly the impurity ions are implanted obliquely from the periphery of the electrode 23. Accordingly, the impurities can be implanted in sufficiently equal concentration to the entire side together with the upper surface of the electrode 23. Thus, when a gate oxide film 24 is then formed on the surface of the electrode 23 by thermal oxidizing, the film 24 of desired thickness is uniformly formed on the electrode 23.

Filed: 1988-04-18
Abstract: PURPOSE:To set the locus of the output waveform of an analog recorder to thickness matching with recording accuracy by superposing the analog measurement signal and an artificial noise signal one over the other and setting the amplitude of the artificial noise signal properly. CONSTITUTION:The analog measurement signal S1 generated by a measuring instrument 1 is supplied to the adder 3c of an analog measurement signal processor 3. A clock pulse CP outputted by a clock pulse generating circuit 3a, on the other hand, is supplied as the artificial noise signal SN to an adder 3c after its amplitude width is set to + or -a by an amplitude adjusting circuit 3b. Then the adder 3c adds the supplied analog measurement signal SI and artificial noise signal SN and supplies the resulting analog signal SO to an analog recorder 2. Then the locus of the output waveform of the analog recorder 2 can be set to the best thickness matching with the arrangement position of the analog recorder 2 or the desired recording accuracy of the analog recorder 2 by selecting the amplitude of the artificial noise signal SN properly.

Title: Color image receiving tube device
Inventor: SHIMOMA TAKETOSHI
IPC: H01J29/48
Filed: 1988-04-20
Abstract: PURPOSE:To realize a small beam spot on a screen surface and improve an image performance by making a common large bore electron lens the asymmetric lens in which a focusing force in the horizontal direction is weaker than that in the vertical direction. CONSTITUTION:A main electron lens part has the large bore asymmetry electron lens commonly acting to three electron beams, and this asymmetry electron lens is designed so that the focusing force in the horizontal direction acting to an electron beam is weaker than that in the vertical direction. The beam axes of three electron beams entering to the main electron lens of an electron gun are parallel each other, and an individual electron beam is designed so as to emanate stronger in the vertical direction than in the horizontal direction. When the electron beam enters to such the large bore asymmetric electron lens part, the incidence beam receives the lens action of the large bore asymmetric electron lens, the three electron beams projected on a screen are satisfactorily focused, and the individual electron beam becomes a small bore and undistorted. Thus the merit as the large bore lens can be maximumly obtained since the three electron beams, moreover, pass the large bore lens.

Abstract: PURPOSE:To intercept a gas flow in emergency when there happens earthquake or the overspeed of flow by placing a valve body onto a receiving seat disposed on its midway of the fluid path of the valve body and forming a valve seat to a current just under the receiving seat. CONSTITUTION:When there happens earthquake, a valve body 5 falls onto a valve seat 6 from a receiving seat 14, a valve hole 7 is shut and the flow of town gas is intercepted in emergency. When there happens fire, an energizing member 13 formed by a shape memory alloy extends instantaneously and the valve body 5 is dropped onto the valve seat 6 when an ambient temperature reaches some predetermined value previously determined. When the velocity of flow in a fluid flow path 4 becomes excessive, pressure difference between the upper and lower currents of the valve body 5 increases, and the valve hole 7 is shut similarly. Accordingly, the valve having a multifunction automatically intercepting the flow in emergency when there happen earthquake, fire, gas leakage and the overspeed of flow can be obtained.
