Title: Equipment for inspecting board in vacuum
Inventor: SERIZAWA MASAYOSHI
IPC: G01N21/94
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To specify a step and a facility where a foreign matter is produced and to take a countermeasure by irradiating the surface of a board in the vacuum with a laser light emitted from an illumination system of an inspection unit on a vacuum chamber and detecting a scattering light from the dust by means of a detection system. SOLUTION: A wafer 1 processed by a process unit is introduced through a transfer mechanism into a vacuum chamber in order to inspect a dust particle on the surface. An inspection unit 21 comprises three detection system 25 and six illumination systems 22 located on the opposite sides thereof. Light from a semiconductor laser 23 in the illumination system 22 is refracted through a reflector 14 and imaged as an linear illumination 24 on the surface of the wafer 1. A scattering light is generated when a foreign matter is present and received by a detection lens 26 in the detection systems 25. In order to scan the entire surface of the wafer 1, an X stage is reciprocated continuously and a Y stage is stepped by means of an XY stage. According to the method, the cause for generating a foreign matter can be detected quickly and a countermeasure can be taken quickly.

Title: Semiconductor device and inverter device provided therewith
Inventor: SAKURAI NAOKI
IPC: H01L29/744
Filed: 1994-07-25
Abstract: PURPOSE:To provide a semiconductor device small in leakage current and low in power loss. CONSTITUTION:A semiconductor switching device is possessed of a PN junction composed of a first conductivity type P<+> first semiconductor layer 1 and a second conductivity type N second semiconductor layer 2 which is wider in band gap than the first semiconductor layer 1.

Title: Dish washer
Inventor: IKEDA TOMOKO
IPC: A47L15/00
Filed: 1988-07-12
Abstract: PURPOSE:To prevent bad oder of contaminant on a dish (such as smell of fish, smell of a curry and so on) from remaining in the interior of a washer by washing a dish within a specified temperature range using peroxide end a detergent. CONSTITUTION:Dishes are washed within the range of 50-70 deg.C using peroxy chemical compounds such as sodium percarbonate, potassium percarbonate sodium perboric acid or the like and a detergent special for washing dishes. If the temperature is under 50 deg.C, the reactivity of the peroxy chemical compound is not good enough to remove the odor of the interior of a dish washer. If the temperature exceeds 70 deg.C, the durability of a dish made of material such as synthetic resin or the like can not be kept. When the peroxy chemical compound is dissolved in water, it changes into hydrogen peroxide. and further perhydroxy ions generated when it reacts with alkaline water solution decompose amines aldehydes and so on, which are generated from contaminants on a dish and the principal components of the bed smell to have low molecular weight and remove the odor. Further, some of residue which is a main generating source of the odor is also decomposed and dissolved to be washed away, whereby the odor is removed.

Abstract: PURPOSE:To provide the plastic optical fiber having high heat resistance and the excellent reproducibility of exit light by forming a core layer of a silicone resin contg. coloring agents. CONSTITUTION:The core layer of the plastic optical fiber consisting of the core layer and clad layer consists of the silicone resin contg. the coloring agent, of which the max. absorption wavelength in a visible light region exists in a 550 to 700nm range. The coloring agents to be added to the silicone resin of the core layer are required to be dissolved in the silicone resin of the core material. Such coloring agents are preferably oil-soluble dyes of an anthraquinone system, phthalocyanine system, triphenyl methane system and are more preferably the dyes of a phthalocyanine system if heat resistance is taken into consideration. The silicone resins may be properly selected and adopted from commercially marketed coloring agents. The effect is insufficient if the amt. of the coloring agents is too little. Transmission loss increases drastically and exist light colors blue if the amt. thereof is to much.
