Abstract: PURPOSE:To facilitate the increase in density and to reduce a junction leakage by arranging a gate active region almost vertically to an insulative substrate and fabricating a vertical thin film transistor in which a source, a gate and a drain are arranged in vertical direction, by self-alignment using an ion implantation method. CONSTITUTION:A polysilicon layer 12 which is reduced the resistance by doping with impurity is deposited on an insulative substrate 11 made of crystal and etc., in order to form a gate electrode and the gate electrode 13 is formed by pattern etching. Next, the exposed surface of electrode 13 is covered by an SiO2 film 14 and the polycrystalline layer 15 the ends of which extend on the substrate 11 is spread with including said film 14. N type impurity ions are implanted there to produce N<+> type regions 22, 21 and 23 in the part above the electrode 13 and the extended part. After that, the whole substrate is covered by an SiO2 film 16 and apertures are opened on the regions 22, 21 and 23 respectively to attach Al electrodes 32, 31 and 33 to these regions. Thus the mask for forming the regions 22, 21 and 23 becomes unnecessary thereby increasing the density.

Abstract: PURPOSE:To facilitate the thickness control of a polySi film for simplifying the manufacturing processes by a method wherein a polycide gate in inversed T type is formed using the difference in the oxidation rate of a silicide film and the polySi film. CONSTITUTION:A gate oxide film 12 and a phosphorus-doped polySi film 13 are formed on a P-type semiconductor substrate 11. A high melting point metal is evaporated and heated on the film 13 to be formed into a silicide film 14 thus a polycide structure is formed. A resist film 15 is formed on the film 14 and then the films 14, 13 are etched away using the film 15 as a mask to form a polycide gate 16. When the film 15 is removed and the polycide gate 16 is oxidized, the polycide gate 16 takes the inverted T shape since the oxidation rate on the film 14 is higher than that of the film 13. Then, the films 13, 14 are covered with another oxide film 17. Next, As ion is implanted in the film 12 to form n<+> source drain layers 18. Finally, the film 17 and the film 12 excluding the part below the gate 16 are etched away and implanted with P ion to form n<->source drain layers 19.

Title: Production of electrophotographic photoreceptor
Inventor: MURAI KEIICHI
IPC: G03G5/14
Filed: 1979-02-13
Abstract: PURPOSE: To improve the insulation characteristic, electrical and physical durability, adhesiveness to photoconductive layer, etc. of an insulation layer by dipping a member having a substrate and photoconductive layer in the coating which contains photosetting type synthetic resin then pulling it up and subjecting the same to ultraviolet ray setting treatment.  
     CONSTITUTION: After a member having a substrate and photoconductive layer is dipped in the coating which contains photosetting type synthetic resin, it is pulled up. Next, powerful ultraviolet rays are radiated to this member and this causes the photosetting type resin to set and react instantaneously. This reaction will not progress further by the slight light incessantly radiated during the repeated use and heat and corona discharge in the copying machine. Hence, the dielectric constant of the insulation layer hardly changes; moreover, crosslinking density is high in the photosetting type resin and therefore the dielectric strength as the insulation layer and surface corona degradation are far superior to other resins. In addition, the coating is evenly applied and the thickness of the insulation layer may be made to optimum one in compliance with the kinds of the photoconductive layer.

Title: Camera provided with automatic focus controller
Inventor: YAMAJI MASAYOSHI
IPC: G03B3/12
Filed: 1981-02-04
Abstract: PURPOSE:To control an electromagnetic for stopping a distance adjusting member with small current by constituting said electromagnet of a yoke formed of two magnetic material pieces sandwiching a permanent magnet and energizing coils wound on said yoke. CONSTITUTION:In the state that no energizing current is flowed to energizing coils 5, 6, an armature 1 forms a magnetic circuit by being attracted to one end of a yoke 2 consisting of a magnetic material by a magnetic flux of a permanent magnet 4 overcoming a spring 3, and a permanent magnet forms a by-pass magnetic path  at the other end of the yoke. When current is supplied to the energizing coils, the  magnetic flux by the energizing coils passes through the by-pass magnetic path provided to the yoke and therefore the armature is released by less magnetomotive  force. When a focusing detecting circuit detects focusing by turning of a distance  ring, the stopping of the adjusting member driving the distance ring is accomplished  by releasing of the armature by the supply of current to the energizing coils.
