Title: Static induction type thyristor
Inventor: NISHIZAWA JUNICHI
IPC: H01L29/739
Filed: 1987-03-12
Abstract: PURPOSE:To obtain a static induction type thyristor especially suitable for an operation under a big electric current by a method wherein the static induction type thyristor can have an improved structure by widening the effective channel width in such a way that an impurity slope is provided at a channel region. CONSTITUTION:An n<--> type region 18 whose impurity density is lower than that of an n<-> type channel region 13 is provided at a place adjacent to an n<+> type cathode region 12 which is to create an intrinsic gate. The n<-> type region 13 whose impurity density is comparatively high generates a big potential difference by ionization (by causing a depletion layer), while the n<--> type channel region 18 whose impurity density is low generates only a small potential difference even by ionization. In addition, in the OFF state, the potential of the channel rapidly increases and an electric current is turned off quickly. At the same time, the potential in relation to a hole at the n<--> region 18 is lower than at the n<-> region 13. In the case of an operation mode to turn on a p<+> type gate region 14 by a forward bias, the holes implanted from the p<+> type gate region 14 are concentrated at the n<--> type region 18 so that they can effectively function in order to take out an electron from the n<+> type source, region 12.

Filed: 1995-02-23
Abstract: PURPOSE: To lessen the movement of an image plane with a temp. change by setting the distance between a light source and a collimator lens in such a manner that the distance is adequately changed by temp. CONSTITUTION: The change in the distance between the light source (semiconductor laser 11) and the collimator lens 21 affects most the movement of the image plane. The material of the part coupling both is, therefore, adequately selected, by which the movement of the image plane by the temp. change of the optical characteristics is confined within the permissible value or below even in the absence of special mechanisms. Namely, the semiconductor laser 11 is inserted into an LD holder 12 and the collimator lens 21 are mounted at a collimator lens barrel 23. The LD holder 12 is fixed by screwing to an optical base 91 and the collimator lens barrel 23 by an adhesive thereto.  The movement of the image plane is minimized by selecting the structure and the material of the mechanisms parts in such a manner that the distance between the semiconductor laser 11 and the collimator lens 21 is changed under a specified condition by the temp. in such a manner.

Title: Optical device for introducing light to spectroscope
Inventor: OKUBO KAZUAKI
IPC: G01J3/02
Filed: 1991-03-25
Abstract: PURPOSE:To realize an optical system for introducing light to a spectroscope wherein lighting conditions for a dispersive element are not changed even if the light distribution, the size and the wavelength of a light source are changed by arranging a diffusing plate, a concave mirror, a spectroscope and an incident slit at the specified positions with respect to the light from the light source. CONSTITUTION:The light from a light source 1 is cast on a diffusing plate 2 having the semi-diffusing reflection characteristic at an incident angle alpha. A concave mirror 3 is arranged on the light path having the optical-axis angle phi=-alpha+ or -(alpha/2) with respect to the regular-reflection optical axis for the incident light to the plate 2. The reflected light is guided into an incident slit 5 of a spectroscope 4. At this time, the distance between the light source 1 and the diffusing plate 2 and the positions and the sizes of the diffusing plate and the concave mirror 3 are determined based on the size of the light source 1 so that the reflected light component enters into the range of the field-of-view angle of the incident slit 5 of the spectroscope 4. Thus, the optical system for the spectroscope 4, which guides the light into the incident slit 5 of the spectroscope 4, is formed. In this way, the optical system, where in the lighting conditions on a dispersive element are not changed even if the light distribution and the size of the light source 1 are changed in space and the wavelength is changed in anyway, is obtained.

Filed: 1994-03-04
Abstract: PURPOSE:To discharge jetting air through an air discharge opening in a state in which fog drops are not contained, by sucking gas in a container by making the jetting air of a pnumatic pump act on an ejector. CONSTITUTION:Compressed air is jetted to a check value 10 through an air discharge opening 6. The check valve 10 is floated due to the buoyancy of jetting air, and jetting is carried out through the jetting nozzle 16 of an ejector, and absorptivity is obtained at a suction opening 17. By this absorptivity, gas containing the offensive small of a deodorant or the like is sucked from a container 20, and at the same time negative pressure is brought on, and the deodorant or the like is evaporated, and leading to the jetting opening 18 of the ejector is carried out, and discharge is conducted through an air discharge opening 21 in the state of being diluted further while the check valve 10 is being passed through and air is being sucked through a slit 21a. The scatterer of a deodorant or the like discharges the gas in the container, so discharge is not made in a fog drop (a large particle) state, and effectiveness is especially displayed for the sap or the like of a sun tree that takes effect even if the sensing value of the deodorant or the like is extremely scanty. By the scent of the sun tree, insecticide effect against a tick, a cockroach or the like is displayed, and at the same time effect to soften feeling by aroma is also realized.

Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To precisely estimate the shape of longitudinal-cut steel plates even in the case of being a rapidly cooled thick steel plate, by estimating the temp. in the center part of the plate thickness at the same position as the position of the longitudinal direction and the width direction of the plate from the temp. distribution of the plate width direction in the longitudinal direction of the plate on the front and the back surfaces just before and just after hot-straightening of the hot-rolled steel plate and obtaining the temp. distribution in the plate thickness direction, and the residual stress distribution after cooling the steel plate. SOLUTION: The temp. distribution in the plate width direction at one or more directions in the plate longitudinal direction on the front and the back surfaces of the hot-rolled steel plate 8, is measured with thermometers 1a, 1b just after hot-leveller 11 and these data are transferred to an analyzer 3 to estimate the temp. in the center part of the plate thickness direction at the same position as the position of the longitudinal and the plate width direction.  The temp. distribution in the plate width direction is calculated from the temp. and the front and the back surface temps., and the temp. distribution in the plate thickness direction is calculated from this temp. distribution and the front and the back surface temps., and the residual stress distribution after cooling the steel plate is calculated from the temp. distribution of the plate width and the plate thickness direction. The steel plate shape after longitudinally cutting the steel plate, i.e., the bending quantity of the longitudinal-cut steel plate as the steel plate deformed quantity is predicted from the residual stress distribution.
