Title: Microwave power synthesis circuit
Inventor: KASHIYUU KEIICHIROU
IPC: H01P5/16
Filed: 1981-12-22
Abstract: PURPOSE:To realize a microwave power synthesis circuit consisting of a few number of hybrid circuits and having the same functions as conventional circuits, by inserting a pi/2 phase shifter between either one of the 2nd and the 3rd terminals of a microwave branch circuit and a reflection type amplifier. CONSTITUTION:A signal incoming from a terminal 38-1 enters a terminal 39-2, and is returned from reflection type amplifiers 41, 42 through reflection, and because of the presence of a pi/2 phase shifter 45, the signal is returned to the terminal 39-2. Further, the signal also enters an inlet 40-1 with pi/2 phase shift and is returned to the inlet 40-1 with the presence of a pi/2 phase shifter 46 and reflection amplifiers 43, 44. As a result, the synthesized signal is outputted at a terminal 38-2. In constituting the power synthesis circuit for 2<n>-sets of amplifiers, convenional systems require 3.2<n-1>-2 sets of amplifiers, while this system requires only 2<n>-1 sets of amplifiers.

Filed: 1981-12-21
Abstract: PURPOSE:To prevent the defective conveyance of a sheet sensitive material due to the static electricty, by setting a supporting member of the sheet sensitive material having a smooth surface at a position above the conveying path of the 2nd conveying system and a little more backward of the 2nd conveying system compared with the conveying path of the 1st conveying sytem. CONSTITUTION:The 2nd conveying system C is provided with a pair of rollers 1 and 1' which receive a film F which is fed from the 1st conveying system BD and a film supproting bar 3 which is provided at a place a little bit backward of a belt conveyor 2 which conveys the film F in the direction approximately rectangular to the film conveying direction of the system BD. In this case, the bar 3 has a smooth surface, and the film F slides on the bar 3. The film F is received as if it touched the conveyor 2 at its tip. As a result, the contact area is reduced between the film F and the conveyer 2. This can prevent the defective conveyance owing to the static electricity.

IPC: F21V5/00
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a headlamp giving great flexibility to optical design with its interior made hard to see to some extent without losing sense of high brightness for its internal metal, and provide a manufacturing method of a reflector in the handlamp. SOLUTION: This headlamp uses a concave lens 4 or a convex lens 5, and a reflector 6 or 7 for controlling light distributing pattern to a prescribed one. Because the concave lens 4 or convex lens 5 is used. The refraction of light makes the interior hard to see, to some extent, without losing sense of high brightness for internal metal. Reflection light L24 or L25 reflection-controlled by the reflector 6 or 7 can be further refraction-controlled by the concave lens 4 or convex lens 5 and applied as outgoing light L34 or L35 to the outside, and therefore great flexibility is given in optical design. The reflector 6 or 7 can be manufactured with high accuracy at high speed and with high flexibility, by using a computer to process, according to a prescribed program, a tentative set-up process as well as a slippage calculation process of a reflector 2, and a final set-up process of the reflector 6 or 7.

Title: Induction type electric apparatus utilizing evaporative cooling
Inventor: OKUBO HITOSHI
IPC: H01F27/18
Filed: 1987-08-25
Abstract: PURPOSE:To simplify a structure, and to improve cooling performance by evaporative- cooling a coil, which has a comparatively large calorific value among sections of an electric apparatus body, by dipping it in a condensable gas and utilizing the heat of vaporization of the gas, and cooling other sections such as a core by a non condensa ble insulating gas. CONSTITUTION:When heat is generated by a coil 3 in a vessel 4, a condensable liquid 5 being in contact with the coil 3 is heated and vaporized, and the coil 3 is cooled at that time. Consequently, vapor changed into bubbles rises in the condensable liquid 5 and collects in a vapor reservoir 9 in an upper section in the vessel 4, and enters into a heat exchanger 7 in the upper section of a tank 1 through pipes 6a, 6b. The vapor of the condensable liquid 5 is robbed of heat during a time when it passes through the heat exchanging pipes and cooled and liquefied, and the liquefied condensa ble liquid 5 is returned into the vessel 4 again through the pipes 6a, 6b from the heat exchanger 7. The coil 3 is cooled by the circulation. On the other hand, heat-generating sections (a core 2, etc.) except a coil 3 section are robbed of heat by a noncondensable insulating gas 8 filled into space except the inside of the vessel 4 in the tank 1 and cooled.

Title: Liquid phase epitaxial growth
Inventor: TSUBAKI KOUTAROU
IPC: H01L21/208
Filed: 1981-12-25
Abstract: PURPOSE:To realize excellent epitaxial growth by introducing H2Se or H2S under the growth ambient in order to suppress vaporization of Se, S. CONSTITUTION:H2 and H2Se are supplied to the quartz reaction pipe 1 during growth, H2Se is decomposed into H2 and Se, thereby the Se ambient is generated in the pipe 1. A slider 2 is moved at the grwoth start temperature, after the ZnSe substrate 4 is placed in contact with the Bi solution 5 on the substrate holding plate 5, a temperature is lowered and CuGaSe2 crystal is formed on the substrate 4 under the Se ambient by the liquid phase epitaxial growth. Vaporization of Se from the substrate 4 and solution 5 is suppressed under the Se ambient, and thereby Se is not separated from the surface of substrate 4 and molar fraction of Se in the solution 5 is not reduced largely. Accordingly, the substrate surface is not deteriorated and mol ratios of Cu, Ga, Se in the solution 5 are also kept to the stoichiometric composition, and thereby ideal liquid phase epitaxial growth can be realized.

IPC: F21V8/00
Filed: 1994-08-11
Abstract: PURPOSE:To provide a light-guiding board of a thinner form and of a much higher luminous efficiency, by employing a molded product which has prisms composed of fine unevenness formed on its light-emitting surfaces in a planar light-emitting apparatus. CONSTITUTION:Fine unevenness is formed on the light-emitting surface 20A of a light-guiding board 20, and the fine unevenness acts as prisms which give a directional pattern to rays of light emitted from the light-emitting surface 20A. Heights h of projecting parts composing prisms range from 10 to 100mum and intervals between projecting parts range from 5 to 100mum. Fine unevenness is also formed on the reflecting surface 20B of the light-guiding board 20, and the fine unevenness acts as prisms which give a directional pattern to rays of light reflected by the reflecting surface 20B. The unevenness-made prisms on the light-emitting surface 20A and the reflecting surface 20B are formed in one body with the light-guiding board 20, and are easily manufactured by molding. Rays of light in the useful direction thereby increase, utilization rate of light becomes higher, and a high luminance is gained with a relatively small amount of input power.

Abstract: PURPOSE:To obtain output picture of excellent picture quality, by balancing the resolution and gradation of the output picture and distributing threshold level of a comparison matrix so that the basic space frequency of the output picture is kept at constant. CONSTITUTION:The gradation is expressed by the combination of brightness contrast of each minute picture element in a matrix of nXn(8X8) sets of minute picture elements sectioning the picture element constituting a picture into small sections. The contrast of each minute picture element is determined at a comparison matrix (see Figure) which sets the n<2>(0-64) stages of threshold levels to each small section. In this case, the comparison matrix is qually divided into m(e.g., 4) square regions (dividing longitudinal and lateral parts at the center) and the threshold level having an equal level difference corresponding to each square region is set. As to the 1st-m-th stage of threshold levels, one small section corresponding to each square region is further divided into m regions and of threshold values of m-stages are set to the minute sections.
