Patent JP-H02199704-A (JP)
Title: Long-sized lamp for vehicle with single light source
Inventor: SATO TAKASHI
IPC: F21S8/10
Filed: 1989-01-27
Abstract: PURPOSE:To make it possible to cause a light emitting surface of a large width to emit uniform intensity of light with a single light source by emitting parallel light beams of less attenuation with respect to distance with a fresnel lens in right-left directions in which a lighting device extends its width, and disposing in the light path of the parallel light beams a plurality of reflecting surfaces of a same shape for deflecting the light beams by reflection in the direction of irradiation. CONSTITUTION:Light beams from a light source 3 produce parallel light beams directed to the left with a left fresnel lens 4L, parallel light beams directed to the right with a right fresnel lens 4R, and parallel light beams directed to the front with a front fresnel lens 7. Because a left inner lens 5L with entire surface formed with left prism cuts 6L is disposed in the path of the light beams directed with the left fresnel lens 4L, all the parallel light beams are deflected at right angles with the left prism cuts 6L and enter a lens 2. Because the respective left prism cuts 6L are of a same shape, light beams entering the lens 2 are also parallel. As a result, the light beams incident on the lens 2 also have the same uniformity with that of the parallel light beams.

Title: Device for deciding quality of laser welding
Inventor: TAKAHASHI YUKIO
IPC: B23K26/064
Filed: 1995-02-07
Abstract: PURPOSE: To uniformize penetration by discriminating the condition of penetration of a work on-line with high precision without being influenced by the secular change of a photoreceiving system and thereby controlling a laser output based on this decision result. CONSTITUTION: A spectroscoping is made by a spectroscopic prism 22 on a radiant light beam Le from a welding zone when a work 1 is irradiated with a laser beam Lb, and conversion is made to pulse trains dependent on the spectrum. Among these pulse trains, each pulse signal of two wave length reflecting the temperature of the welding zone is extracted in a signal processing circuit 24; from the light intensity of that wave length, the temperature Dt of the welding zone is determined; and based on the temperature Dt of the welding zone, the normal/defective condition of penetration is discriminated.

Title: Gum toothbrush
Inventor: EDOWAADO ERU KOURUSUN
IPC: A46B9/04
Filed: 1993-01-11
Abstract: PURPOSE: To provide a toothbrush for peridentium by which forming of dental plaque and dental calculus are suppressed and tooth can be maintained in a clean and healthy state. CONSTITUTION: If a bunch 22 of respective bristles are divided into a transverse row with odd numbers and a transverse row with even numbers viewed from a tip side of a toothbrush head 12, the bristles constituting the transverse row with odd numbers in the bunch 22 have the same length and the bristles constituting the transverse row with even numbers in the bunch 22 have shorter length than those with odd numbers and also have the length which are gradually increased toward far away positions from the tip end side of the toothbrush head 12. Since the brush has a structure for entering the bunch 22 of multiple bristles into spaces between adjacent teeth of tooth gingival tissues which support teeth, the brush can prevent accumulation of dental plaque which may cause severe peridentium diseases, thus looseness of teeth as well as damages on the tooth gingiva and bone structure supporting the teeth.

Filed: 1988-01-28
Abstract: PURPOSE:To enable detection of a stroke without being affected by a change in environmental temperature, by detecting capacitance of an electrode for detecting stroke through a first shield wire part to compensate the results by a capacitance of an second shield wire part. CONSTITUTION:A hole part 14 is formed at a rod section 13 of a cylinder device 11 and one end of an electrode 15 is inserted into the hole 14 to be fixed on a cylinder section 12.

Title: Dry etching method of silicon compound
Inventor: ODA TAKAFUMI
IPC: H01L21/302
Filed: 1983-02-07
Abstract: PURPOSE:To execute tapered etching to a silicon compound such as PSG, etc. by executing the etching in two stages, in the first stage, H2 concentration is lowered or eliminated and in the second stage, H2 concentration is raised. CONSTITUTION:In the case of CF4+H2 mixed gas, in the first stage, etching is carried out with concentration of H2 around the point B in the figure. At this time, since an etching rate of resist layer 3 is high as compared with that in high concentration of H2, the edge of resist layer 3 goes backward toward the position 6 from the position 5. Since a material 2 to be worked allows vertical anisotropic etching to the lower side, the edge is tapered. Before the etching of aperture reaches the Si substrate, the etching in the second stage starts, causing increase of concentration of H2 up to the point A in the figure. The etching is carried out at this concentration until it reaches the substrate 1. Thereby, edge of material 2 to be worked is tapered.

Abstract: PURPOSE:To expand a dynamic range and to reduce a dark current noise by a method wherein an photoelectric conversion is executed without impressing a reverse bias voltage on a photodiode and a signal charge which is converted optoelectrically is controlled by a voltage-to-current conversion transistor. CONSTITUTION:A voltage VOC between both electrodes of a photodiode PD change its level in accordance with the quantity of light hnu, and is used as a gate voltage of a voltage-to-current conversion transistor Tr2. Accordingly, an electric current between a drain and a source of the transistor Tr2 corresponds to the interelectrode voltage VOC, and a voltage-to-current conversion is executed. An electric charge accumulated in a charge accumulation capacitor CS is controlled by the electric current between the drain and the source; an output signal which is integrated in terms of the time is read out by using a readout circuit. while an electric current is accumulated in the charge accumulation capacitor CS, a reverse bias is not impressed on the photodiode PD. The voltage VOC between both electrodes displays a logarithmic characteristic with reference to the large quantity of light; a dynamic range of a reproducible input signal becomes large. A dark current is not generated in the photodiode.
