Patent JP-S63170968-A (JP)
Title: Semiconductor device and its manufacture
Inventor: SHIBATA KENJI
IPC: H01L21/8247
Filed: 1987-01-09
Abstract: PURPOSE:To enhance the accuracy to control the film thickness of a tunnel oxide film by a method wherein a nitride film is formed on the surface of a gate oxide film at a semiconductor device which has the thin tunnel oxide film at a part of the gate oxide film formed on the surface of a semiconductor substrate. CONSTITUTION:A nitride film 3 is formed on the surface of a gate oxide film 2. That is to say, a resist layer 6 is coated on the nitride film 3; an opening is made at the nitride film 3 by making use of the resist layer 6 as a mask; the resist layer 6 is removed; after that, the opening is made at the gate oxide film 2 by making use of the opened nitride film 3 as the mask. Because the nitride film 3 can be used as the mask in this way, it is possible to remove the resist layer 6 before the opening is made at the gate oxide film 2. Accordingly, because a mixed acid as a resist remover does not touch the surface of a substrate 1, a natural oxide film is not formed; it is possible to control a film thickness t0X accurately during a subsequent process to form a tunnel oxide film 7. &X:A: field oxide film.

Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To provide a game device capable of informing the variation of an allotment factor of a player. SOLUTION: A control part 20 calculates a return rate and the number of initial bets on an object in accordance with a virtual initial allotment factor. When a player bets in reference to the initial allotment factor, the control part 20 conducts predetermined weighting from time to time by multiplying the bets of the player by a weighting coefficient and adds the number of weighted bets of the player on the object to the number of initial bets to find the number of new bets on the object and calculate the number of new total bets. The control part 20 recalculates the allotment factor in accordance with the number of new bets on the object and the number of new total bets and renews the allotment factor to be displayed on a display 80 at predetermined time intervals.

IPC: F01L9/04
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetically-driven valve system for an internal combustion engine to improve responsiveness during high speed operation and hardly cause the occurrence of surging. SOLUTION: A disc-form plunger 5 is fixed on the valve stem 2 of a valve element 1, and electromagnets 6 and 7 to attract the two surfaces of the plunger are arranged on the two surfaces of a plunger 5 in a state to be positioned facing each other. First and second springs 8 and 9 are brought into contact with the two surfaces of the plunger 5 and the plunger 5 is energized toward the intermediate position between two attraction positions. One first spring 8 is arranged on the inner peripheral side of the electromagnet 6 and the other second spring 9 is arranged on the outer peripheral side of the electromagnet 7. By bringing the central part and the outer peripheral part of the plunger 5 into contact with the springs 8 and 9, inclination is prevented from occurring and responsiveness during high speed operation is ensured.  By differing the coil diameters of the springs 8 and 9 from each other, surging is prevented from occurring as a spring constant is decreased.

Abstract: PURPOSE:To prevent rader picture data from the generation of lacking even if polar coordinate scanning is converted into rectangular coordinate scanning by forming a digital conversion part, a picture memory, screen discriminating code memories, a register, etc. CONSTITUTION:The digital conversion part 1, the picture memory 2, the screen discriminating memories 11, 12, etc. are connected. The rader picture data alphais converted into a digital value by the conversion part 1 and the polar coordinate value of the data alpha is simultaneously converted into a rectangular coordinate value by an input address control part 3. Picture data and a discrimination code stored in an address corresponding to the coordinate value are outputted from the memories 12, 11 respectively and stored in registers 10, 15 respectively. In addition, whether the data alpha is to be added to the data stored in the register 10 or not is determined. In this case, it is defined than the picture discrimination code '1' is the current screen and the code '0' is the preceding screen, and both the values are not added when the code of the register 15 is '0' and added when the code is '1'. Simultaneously, the codes '1' and '0' are inputted to the memories 11, 12 respectively. Consequently, the data alpha can be prevented from the generation of lacking even in the rectangular coordinate scanning.
