Filed: 1989-09-25
Abstract: PURPOSE:To prevent drop in a manufacture yield caused by a residual accumulated electrode material by selectively removing an insulation film on a region except a part required for forming a gap under a storage electrode prior to attaching a conductor layer. CONSTITUTION:Prior to patterning of a storage electrode 12, a region which is not needed to form a gap 13 under the electrode 12, for example an SiO2 film 16 for forming the gap on a region A2 for forming a peripheral transistor Tr2, is selectively removed. Therefore at the time of patterning the storage electrode 12, a residual caused by dust at the time of exposing a residual 112B of a polysilicon layer being a material of the electrode 12 to be left and attached to a step on a region other than a memory cell forming region A1 is immediately attached onto an Si3N4 film 10 which does not solve in HF solution. Therefore the device is free from lift-off due to wet etching treatment with the HF solution at the time of forming the gap 13, as well as the Si layer residual 112B, etc., can be prevented from attaching via etching solution to an important part on a substrate such as under the electrode 12. Thus a manufacture yield can be improved.

CONSTITUTION:Refrigerant gas, given compression work in an operative chamber 16, is recirculated to a part, where the operative chamber 16 performs an expansion stroke, through a bypass passage 24. In a suction stroke, where the operative chamber 16 is spread by turning a rotor 14 and a vane 15, the recirculated bypass refrigerant gas expands acting on the vane 15 with the compression work, obtained till then, serving as expansion work. In this way, energy of the refrigerant gas, allowed to bypass flow for controlling delivery volume, is effectively recovered, and the delivery volume can be controlled with no worsening of compression efficiency. While a compressor, providing a reverse flow preventing valve in suction ports 17, 18, prevents also a decrease of suction efficiency from being generated due to a reverse flow of the refrigerant gas.

Title: Game machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a game machine which can keep a player's expectation for a big win by advantageously deciding an amount of prizes to be awarded to the player based on the result of plural lotteries. SOLUTION: The total frequency of time reduction to reduce the symbol variation period (size of a privilege) is decided (S100) based on the first frequency of time reduction drawn by a lottery when it is decided whether a big win is hit or not and the second frequency of time reduction (S90). So a player can keep hope for a reduction of the symbol variation period (privilege) even after the first frequency of time reduction is decided (after the first lottery is drawn). And as the symbol variation period is reduced after the big win play, the frequency of symbol variation per unit time is increased. Therefore, a player can get more chance of a big win.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To ensure wide detection area in short distance maintaining small the swivel angle of scanning by making part of a light projection window special shape refracting outside and diffusing the projecting light. SOLUTION: A light projection window 10 constituted of such material transmitting light as transparent or semitransparent glass and synthetic resin is a window with normal plane shape near the front where a large detection distance is necessary and is placed so that the curved surface of grooves 11 and 12 comes at a part of outside of projection light cast to the diagonal front direction where a large detection distance is unnecessary. In the case the projection light is cast in diagonal front by scanning, a part of outside of the projection light goes in the curved surface of the grooves 11 and 12, the light path of the part of the projection light bends outward following the Snell laws of refraction and part of the projection light is cast diagonally in both sides of left and right as diffusion light eventually.  In this case, remaining projection light is casted as normal collimated light and the beam profile of the projection light widely distributes in horizontal direction.
