Title: Refracting state display method, game system, and computer-readable recording medium recorded with game program
Inventor: ISOBE KEIICHI
IPC: A63F13/837
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To give a user an incentive to play a game by representing straight propagation and refraction of light on a screen by drawing and refracting the representation of the refraction of light only when the light is made incident on a specific body among bodies displayed on the screen. SOLUTION: While the player presses a specific button of a controller, laser obj as an object is projected from a player character SC. This laser obj draws an image to represent a visual state wherein the light is made incident on refracting bodies Wa1 and Wa2, refracted in the refractive bodies Wa1 and Wa2, and then projected from the refracting bodies Wa1 and Wa2. When the laser obj's projecting from the refracting bodies Wa1 and Wa2 impinge on an enemy character DC, the life of the enemy character DC decreases during the period. Consequently, an incentive to play the game can be given by visual variation.

Title: Optical measuring apparatus
Inventor: NISHIHARA SADAMITSU
IPC: G01B11/08
Filed: 1984-07-26
Abstract: PURPOSE:To eliminate the measuring error, which is liable to occur at the end surfasce of a material to be measured, by counting clock pulses during the period the material to be measured is scanned by a counter, and sequentially latching the counted contents. CONSTITUTION:A light scanning part 12 projects parallel-scanning measuring light to a material to be measured. A light detecting part 26 detects the change in brightness of the measuring light, which has passed the material to be measured. A counter 32 counts specified clock pulses during the period of light scanning. The length of the material to be measured is obtained by the counted value during the period the parallel-scanning measuring light passes the material t be measured. The counter 32 starts the counting when the measuring light has passed the starting end of the material to be measured. One-time inhibiting circuit 40 inhibits the counting operation of the counter 32 for the specified period for either a pseudo-detected signal, which is transmitted through the material to be measured, or the detected signal, which indicates the ending edge of the material to be measured after the start of counting. A register 38 latches the output value during the count inhibiting period after the output value of the counter has been stabilized.

Abstract: PURPOSE:To prevent leakage of modified gas to the outside, by providing a valve for preventing leakage of modified gas to the outside at the time when an engine is stopped and a hydrogen storing chamber for adsorbing hydrogen of the modified gas the pressure of which is raised by the closing of said valve, and absorbing extraordinarily raised pressure by a light and compact container. CONSTITUTION:When an engine 1 is started, methanol in a fuel tank 9 that is carried under pressure to a fuel modifier 6 by a fuel pump 10 is preheated at a heat exchanger 8. Here, since the modifier 6 is heated by exhaust gas, the preheated methanol is modified and gasified efficiently into a hydrogen containing modified gas. This gasified fuel is carried to the heat exchanger 8, in which it is reversed for a while. When the engine 1 is stopped, on the other hand, valves 11, 15, 17 are closed automatically and the inlet portion of a fuel passage of the modifier 6, a gas passage 12 and the outlet portion of the heat exchanger 8 are closed, so that leakage of modified gas is prevented. Further, when the valves 11, 15 ae closed, pressure in the fuel passage is raised by the modified gas produced in the modifier 6 and hydrogen in the modified gas is adsorbed by a hydrogen occluding layer 13 in a hydrogen storing chamber 14. Here, since the volume of hydrogen in the modified gas occupies 2/3 of the entire volume, the size and pressure of the hydrogen storing chamber 14 can reduced to 1/3 as compared with those of the conventional arrangements.

Abstract: PURPOSE:To enable the change in surface temperature of a deposition film during the deposition process to be reduced by a method wherein, when a metallic film on a semiconductor substrate is formed by CVD using infrared ray irradiation heating, the said metallic film is deposited while slowly diminishing the irradiating intensity of the infrared rays. CONSTITUTION:A chamber 1 arranged with an Si substrate S on a specific position is kept in the atmosphere of non reactive gas; an infrared ray lamp 6 is lighted to heat the Si substrate at a deposition temperature; and then the power of the lamp 6 is adjusted to keep the substrate temperature. Later, a reactive gas is fed to the chamber 1 to start the deposition of the Si substrate S. During the deposition process, the power of the lamp 6 is slowly diminished while keeping on the feeding of the reactive gas. The surface temperature is kept at the specific value. When the thickness of deposited film reaches the expected value after the lapse of specific time from the starting time of the deposition, the atmosphere inside the chamber 1 is substituted with the former non reactive gas to stop the deposition and then the lamp 6 is turned out.
