Title: Game machine, recording medium and variation display method
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To improve a new idea of a game by enhancing the expectation of a player in a variable display. SOLUTION: In a reach (ready-for-winning) pattern at the time of a failure, as a final display mode, a state appearing one step before the display mode of a big hit and a state further varied by one step from the display mode of the bit hit are prepared. In the former, since the display mode of the big hit is coming near before a variation display is finally stopped, the expectation of a player can be enhanced. In the latter, the display mode of the big hit is obtained once until the variation display is finally stopped. At this time, the expectation of the player is more strongly enhanced. In this game machine, patterns of the latter are more prepared than those of the former, so that opportunities that the latter appears are increased to more enhace the expectation of the player.

Title: Manufacture of semiconductor device
Inventor: BUDE JEFFREY DEVIN
IPC: H01L29/792
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To form a gate dielectric layer of high reliability and long lifetime by thermally oxidizing a semiconductor substrate that is damaged by implanting ions to a specified concentration to form a thin dielectric film. SOLUTION: A thin dielectric layer is formed by thermally oxidizing a semiconductor substrate that is damaged by ion implantation. A desired amount of damage is introduced in the semiconductor substrate by implanting dopant atoms or undopant atoms. To assure proper amount of damage, the implanted ion concentration lies between 6×1016/cm3 and 3×1021/cm3. After the substrate is damaged to a desired amount, an oxide on the semiconductor substrate surface is removed by wet etching, and thermal oxidation is made in an oxygen- containing atmosphere in a temperature range from 700 deg.C to 1,100 deg.C to form a thin dielectric layer. Through these processes, a high value of QBD, which is the total electronic charge sustained by the gate oxide until voltage breakdown, results, therefore high reliability of the gate dielectric layer is obtained.

Title: Pressure mitigating device for body of equipment
Inventor: TAKAMIYA HIROKI
IPC: H05K5/02
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To solve a problem that rain water infiltrates into a casing from a vent hole caused by negative pressure generated within the case when the casing is cooled by rain. SOLUTION: In outdoor installation type electronic equipment having the a waterproof casing a pressure mitigating means 3 for mitigating a pressure change within the casing 1 is provided on a part of the casing 1 by varying volume according to the pressure change within the casing 1. Since the pressure mitigating means 3 mitigates the pressure change, even if pressure within the casing varies due to variation of an outside temperature, pressure within the casing 1 can be maintained almost constant. Since a vent hole to be opened to the atmosphere is not required to be provided in the casing 1, rain water does not infiltrate into the casing 1 from the vent hole, even if negative pressure is generated within the casing 1.
