Title: Equipment and method for measuring optical characteristics, and recording medium
Inventor: KIMURA EIJI
IPC: G01M11/00
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To obtain an equipment in which waveform distortion of outgoing light can be reduced when a light having wavelength within a specified narrow range enters an optical fiber. SOLUTION: The optical characteristics measuring equipment comprises a light source system 10 for supplying an incident light to an optical fiber line 110, a waveform monitor 42 for measuring waveform distortion of the incident light transmitted the optical fiber line 110, and a section 44 for regulating the output of incident light such that the waveform distortion measured by the waveform monitor 42 falls within a specified range. Output of the incident light is regulated to lower the ratio to noise, i.e., the S/N ratio. Since noise spreads over a relatively wide wavelength range, incident light can be supplied to the optical fiber line 110 over a wide wavelength range when the S/N ratio is lowered appropriately, thereby reduces waveform distortion of outgoing light.

Title: Method for burning organic waste and burner device therefor
Inventor: OTOMARU ATSUO
IPC: F23G5/033
Filed: 2000-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for burning oil for organic wastes and a burner device for the organic wastes, which raises combustion efficiency and maintains combustion with stability in a combustion furnace. SOLUTION: Recovered organic wastes are selectively removed with steel, glass and the like therefrom and crushed by a crusher, followed by pulverization by a mill 83 with the addition of water thereto and liquefaction without the causing of clogging in the burner device. The resultant product is mixed with oil or the like and an emulsifier to obtain a fuel comprising fine powder of the wastes containing fine liquid particles evenly scattered therein and enclosed with the oil or the like. The fuel is pored into a tank and supplied, being agitated, to the burner by a pump at a given rate. When the fuel passes through the burner it is thermally decomposed by hot air, while the hot air turns into a volute hot air by a blade to supply the fuel to a diffusion chamber.  The fuel collides against a guide plate and with the impact, injected for diffusion through a diffusing hole and a gap made between the guide plate and a hot air duct. The hot air again turns into a volute hot air by the blade to supply the fuel to the diffusion chamber. The fuel again collides against the guide plate and with the impact, atomized. Such an injection is repeated several times to obtain the high temperature burner which exerts high thermal efficiency from the atomization cylinder to the combustion furnace.

Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 2000-07-14
Abstract: PROBLEM TO BE SOLVED: To avoid a trouble in control caused by an unexpected electric power failure which may rapidly be restored by keeping a controlling state. SOLUTION: A power source substrate mounts a reset control circuit for supplying a reset signal and a return signal to respective electric part controlling substrate. When the reset control circuit supplies a reset signal to the CPUs of the respective electric part controlling substrates, a delay circuit 960 delays the reset signal to the CPU of a man substrate. Consequently, when the power source is turned on, a reset signal to the CPU of the main substrate is started later than that to the CPUs of the other electric part controlling substrates. A counter 971 starts counting when a power disconnection signal comes to a low level. A count up value is set to be equal to or larger than a time until power voltage drops to voltage making control operation impossible since the power disconnection signal comes to a low level.

Filed: 2000-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a glass door capable of keeping an open state and releasing the holding state when a torque of a design value or greater acts on the glass door. SOLUTION: A glass frame 20 is formed of a magnetic body and a slope 28 is formed by cutting off a surface corner on the left side part of the glass frame 20.
