Title: Method for molding plastic
Inventor: AZUMA HIDEJI
IPC: B29C45/26
Filed: 1988-08-30
Abstract: PURPOSE:To improve the escape of air and gas by a method wherein a space between a backing plate and a bottom plate is enclosed under the condition that molds are closes and evacuated during the injection of plastic. CONSTITUTION:An ejector plate upper 5 and an ejector plate lower 6 are arranged in a space between a backing plate 10 and a bottom plate 11, which is enclosed by a spacer block 9, a plate 13 and a ring 14. A hose attaching port 15, through which a vacuum generating device 16 is connected, is provided on the side of the plate 13. When molds are closed, a solenoid valve 18 is opened by means of a sequence timer 19 so as to generate vacuum and, after that, injection is started. The air in cavities and generated gas are sucked through clearances between ejector pins 8 and a movable retainer plate 2 in a vacuumized space between the backing plate 10 and the bottom plate 11. After the finish of injection, mold closing is done. At that time, before the start of the pushing-up of the ejector plate lower 6 by an ejector rod 7, the solenoid valve 18 is closed by means of the sequence timer 19, resulting in stopping the actuation of the vacuum generating device 16 so as to release vacuum. The removal of a product from the molds can not be hindered by vacuum.

Title: Semiconductor stack device
Inventor: KIJIMA KENJI
IPC: H01L23/64
Filed: 1981-12-25
Abstract: PURPOSE:To allow the wiring of a GTO element protection circuit in the minimum number of pieces and in the shortest way, by utilizing the GTO element and connecting only between a condenser and a diode by a wiring. CONSTITUTION:The condenser 3A is one terminal type, and has a structure wherein the case itself is constituted of conductive metal and used as one side terminal. For the GTO element, the protection condenser 3A and the diode 4A are mounted directly on terminals 15A and 15B of cooling fins 10A and 10B respectively by non-wiring, then the condenser 3A and the diode 4A are arranged at the position of access each other, and only they are connected by one short wiring 14A. One short wiring as the minimum is enough for the GTO element protection circuit, thereby the circuit resistance is low. Therefore, when the GTO element 1 becomes OFF, the overvoltage instantaneously generated from the reactance of the circuit is smoothly absorbed by the condenser 3A, thus the protection of said GTO element 1 can be securely performed, and accordingly the function can be sufficiently displayed to its maximum.

Title: Dual grid reflector
Inventor: SHIGEMASA HIROYUKI
IPC: H01Q1/12
Filed: 1988-08-30
Abstract: PURPOSE:To correct two grid reflectors independently by supporting the front and rear grid reflectors by a rear face structure respectively. CONSTITUTION:The grid reflector 2 on the rear face is supported by the rear face structure 1 through a reflector support fixture 6 on the rear face only. Furthermore, the grid reflector 3 on the front face arranged on the front face of the grid reflector 2 on the rear face is supported on the rear structure 1 through the front face reflector support fixture 5 not through the grid reflector 2 of the rear face. The front face reflector support fixture 5 supports the front face grid reflector 3 through a throughhole 8 formed to the grid reflector 2 of the rear face. Since the grid reflector 2 on the rear face and the grid reflector 3 on the front face are supported directly by the rear structure 1 with a sufficiently high stiffness respectively, the deformation caused to one does not interfere the other grid reflector. Thus, the deformation caused at formation of the grid reflectors 2, 3 is corrected independently by the rear face structure 1.

Title: Cooler
Inventor: MUROZUMI TOSHIMICHI
IPC: F28F1/32
Filed: 1987-08-28
Abstract: PURPOSE:To enable the cooling operation to be carried out for a long period of time by providing a group of independent fins arranged dividedly in every row of two or more rows on the windward side of the air flow to the fins and providing a group of integral fins having a fin length which is two or more times longer than that of the independent fins. CONSTITUTION:A refrigerant tube 3 penetrates through independent fins 8, integral fins 9 and end members 2 of a cooler 4, and all of the fins are arranged substantially in parallel in the wind direction. During the cooling operation, the independent fins 8 disposed on the windward side have a high coefficient of heat transfer with respect to an air current a, and the cooler performs, as a whole, the highly efficient heat exchange. However, with the lapse of time, frosting develops from the front edge portions of the fins on the windward side in the direction of the air current A. Thereupon, an electric current flows to a radiant heater 5 for defrosting, and as a result, defrosting is carried out by means of both radiant heat from said heater 5 and heat transfer through the fins, thus attaining a non-frosting state after carrying the current for a predetermined period of time. Accordingly, the air side heat transfer coefficient is thus ensured. Further, in the defrosting operation, the heat transfer efficiency of the integral fins on the leeward side is enhanced to reduce the defrosting time, and consequently the cooling operation for a long period of time can be effected.

SOLUTION: This X-ray analyzer has an electron beam emitting device 1; an X-ray spectroscope 2 for detecting the X-ray intensity; an X, Y-stage device for automatically scanning a sample stage 3 in X, Y-directions; and a Z-stage device 5 for making a sample surface follow the focal position of the X-ray spectroscope 2 in Z-direction, the X, Y-stage device 4 automatically scans in X, Y-directions, and the Z-stage device makes the sample stage follow in Z-direction according to the irregularities of the sample surface so that the sample surface is situated in the focal position of the X-ray spectroscope 2. The surface form data of the sample is determined from the X, Y-coordinate of the X, Y-stage device 4 and the Z-coordinate by the movement of the Z-stage device 5.  The composition data of the sample is collected by the X-ray intensity measurement of characteristic X-ray by the X-ray spectroscope 2. Thus, the composition data and the surface form data are simultaneously obtained by one device, and the composition data and the three-dimensional map of the surface form data are displayed on the same map.

Filed: 1990-08-17
Abstract: PURPOSE:To keep a stable arc with no fluctuation for a long period of time by encapsulating Hg, rare gas, Fe, halogen, and a specified amount of Bi in a light emitting tube. CONSTITUTION:Hg, rare gas, Fe, and halogen are encapsulated in a light emitting tube 1 of a metal vapor discharge lamp, and also therein is encapsulated Bi in such an amount that its ratio in gram atom to Fe becomes 1/20 thru 6/1.

Title: Specimen constituent analyzing apparatus
Inventor: TAKEUCHI KAZUNORI
IPC: G01N31/00
Filed: 1981-12-29
Abstract: PURPOSE:To measure amount of constituent in a specimen at high accuracy using a simple apparatus, by a method wherein generated gas in whole amount or in part at uniform concentration is forced into a measuring cell of a gas analyzer and the gas concentration is measured. CONSTITUTION:When oxygen gas is supplied from an oxygen bomb 2 into a combustion chamber 1 and a pot 3 containing a specimen 4 is inserted and a furnace is operated, carbon and sulfer in the specimen 4 become CO2 gas and SO2 gas respectively. These generated gases are forced by a pump 11 through a check valve 12 into a measuring cell 13 and a dummy cell 14 of a gas analyzer 6 such as infrared analyzer for measuring the gas concentration. Then an electromagnetic valve 15 is closed, and a closed combustion measuring system is constituted by the combustion chamber 1, the pump 11, the measuring cell 13, the dummy cell 14 etc. Most of generated gas is fed to the measuring cell 13 and the dummy cell 14. Since amount of gas measured at the measuring cell 13, e.g. CO2 gas is proportional to that of carbon in the specimen 4, if calibration curve of carbon amount and CO2 concentration is previously determined by measuring the standard specimen, carbon amount in the specimen can be known from the measured gas concentration.
