IPC: H01L21/66
Filed: 1990-07-25
Abstract: PURPOSE:To judge a semiconductor material and whether it is good or not by a method wherein an n-d profile is measured, a carrier mobility mu in a region where (n) is changed is measured and a semiconductor interface is evaluated on the basis of both results. CONSTITUTION:A layer B indicates a high-resistance substrate or a part where a high-resistance buffer layer is formed on the high-resistance substrate. A layer A indicates said buffer layer or a semiconductor multilayer film which is formed on the substrate. The buffer layer and the substrate are provided with a conductivity type which is different from the layer A, or are composed of a high-resistance semiconductor whose kind is the same as or different from that of the layer A. A barrier electrode C2 layer is provided between two ohmic electrodes (a), (b) which are faced to the layer A. The two ohmic electrodes (a), (b) which are faced to the layer A are short-circuited, and a Cg-Vg characteristic is measured. In addition, while a low Vds is applied, a gm-Vg characteristic is measured. The Cg-Vg characteristic and the gm-Vg characteristic are converted into an n-d profile and a mu-d profile.

Title: Driving force transmission device
Inventor: ASHIDA SATOSHI
IPC: F16D43/284
Filed: 1990-07-25
Abstract: PURPOSE:To make the startup property of transmission torque extremely good by interposing a resistive member made of elastomer between two members that relatively rotate each other. CONSTITUTION:An annular groove 11d is formed on the side of an inner hole of the inward flange part 11b of an outer case 11, and a resistive ring 18 made of elastomer is fitted to the said annular groove 11d. A resistive ring 18 like this closely contacts the outer circumference of the tube part 12a of an inner shaft 12 at its inner circumference, generating transmission torque between these both 11, 12 when relative rotation occurred between the outer case 11 and the inner shaft 12. Since the aforementioned resistive member always generates transmission torque between two members that relatively rotate in a driving force transmission device having construction like this, it compensates the torque transmission caused by looseness in an area of dead band, and satisfactorily maintains the relation between time and transmission torque in the initial stage of generation of differential rotation.

IPC: H01L21/02
Filed: 1983-10-21
Abstract: PURPOSE:To reduce cost by reducing two specific masks to one by etching with using a specific mask for ion implantation and etching specific marks. CONSTITUTION:After ion implantation of a selective oxidation film 202 and a gate oxide film 203 formed on a substrate 201 by use of a resist pattern 204 including a distinguishable pattern, etching is done to etch the specific marks on the selective oxidation film. If it is applied to a memory for exclusive use of reading, oin implantation for writing contents of the memory is performed at the time after oxidation for removing defects due to the selective oxidation film before oxidation of a gate. After that, etching is done based on the specific resist pattern so as to etch the specific marks on the selective oxidation film. Then, the oxidation film is removed and gate oxidation is performed.

Abstract: PURPOSE:To reduce constructing cost by using a steel pipe pile as core material for soil column line execution method, and after discharging soil mortar in the pile, depositing concrete in the pile to combinedly use as a regular prepared wall for an underground structure. CONSTITUTION:Mortar is filled in a ditch-shaped vertical hole while ditching it, and the collapse of the hole 2 is prevented by a soil mortar 3 stirred with earth and sand. A steel pipe pile 1 is planted in the hole 2 and joined in a body. After a muddy water discharging pipe is inserted in the pile 1 to discharge the mortar 3 in the pile 1, concrete 5 is deposited in the pile 1 to form an earth retaining wall, and pit excavation is executed on its inside. In addition, as occasion demands, a reinforcing bar is arranged inside the earth retaining wall, and the concrete is deposited there to construct a reinforced concrete wall 6 unified with the pile 1. Thus the execution of regular prepared wall can be omitted to shorten the term of work, and the loss of the area on an underground floor can be removed to secure a wide underground space, and moreover a steel frame beam or the like can be directly joined, and leakage occurring just after concrete depositing can be prevented.

Title: Endoscope
Inventor: OONO KUNIO
IPC: G02B6/44
Filed: 1982-11-10
Abstract: PURPOSE:To secure the mutual movement of respective optical fiber elements even if moisture at the inside of an endoscope is slightly increased and to prevent the endoscope from being broken as possible by providing hardness preventing fiber bundle from being crushed flat at the time of bending to sheathing tubes for built-in optical fiber bundle. CONSTITUTION:The respective sheathing tubes 28, 29 consist of silicone rubber, vinyl chloride, etc. and the hardness is selected in a range preventing the optical fiber bundles 26, 27 from being crushed flat at the bending and allowing the optical fiber bundles 26, 27 to be bent. If Shore hardness is selected in the range of 50-70 deg. in case of silicone rubber for instance, the sectional shape is kept at an almost complete roundness. Therefore, the space allowing the optical fiber elements at the inside of the tubes 28, 29 to move is secured, and even if a solid lubricant is moistened and the efficiency is reduced, the optical fiber elements are prevented from strong mutual interference and from being broken, so that the life of the endoscope can be expended.

Abstract: PROBLEM TO BE SOLVED: To suppress the bounding of shutter blades, with a simple constitution, with respect to shutter of a type capable of reciprocating three or more shutter blades by reciprocating an annular or circular-arcuate linkage member in a direction crossing an optical axis. SOLUTION: The actuating pin 10a of an actuating member 10 is fitted into the oblong hole 2a of a linkage member 9. A spring 11 pushes the linkage member 2 upward.

Filed: 1982-11-12
Abstract: PURPOSE:To improve the area of safety operation of a longitudinal MOSFET by arranging a source pad section at the central section of a chip while preventing the arrangement of a unit cell immediately under the pad. CONSTITUTION:The electrode arrangement of the lateral MOSFET consists of a gate electrode 4 made of poly Si, a field limiting ring p type layer 9 for relaxing an electric field, an n<+> type layer 10 for a channel stopper, an Al film 11 resistance-connected to the n<+> type layer 10, etc. The bonding pad S for a source is formed at the central section of the chip, a p type diffusion layer 12 is formed immediately under the bonding pad, and the cell of the MOSFET is not formed to the section. A bonding pad G for a gate is formed at the corner section of the chip separated from the position of the bonding pad S for the source. Accordingly, currents do not flow because the cell of the MOSFET is not formed at the central section of the semiconductor chip to which the bonding pad for the source is formed. As a result, the MOSFET is difficult to be broken. Consequently, the ASO in a small current high voltage region is improved particularly.

Title: Printing apparatus
Inventor: SAKURAI ETSUYUKI
IPC: B41J2/51
Filed: 1984-09-21
Abstract: PURPOSE:To enable the miniaturization, wt. reduction and cost reduction of the power source apparatus of a high speed printer by constantly suppressing the max. value of supply power and eliminating the provision of excessive power capacity, by interrupting printing operation on the basis of the output signal from a detection circuit. CONSTITUTION:Because the current flowing to primary side winding is proportional to a time, the supply of power to a secondary side is performed by detecting the current flowing to a transformer 7 or a transistor 6. Because the current flowing to a resistor 102 detects the supply power in the secondary side in a current detection circuit 5, the potential difference between both terminals of the resistor 102 rises when the all black printing or 50% black printing of one line was performed and a transistor 101 is brought to an ON- state to allow a signal 20 to become LOW. After the signal 20 is insulated from the primary side through an insulating circuit 15, said signal is transmitted to the input port 21 of a microcomputer 10 for controlling the operation of a 24-pin printer.
