Title: Production of multifibers
Inventor: WATANABE MINORU
IPC: G02B6/04
Filed: 1979-07-10
Abstract: PURPOSE: To surely prevent the light leakage from optical fibers by inserting an optical fiber bundle into a glass pipe, then supplying a metal or metal compound into the clearances of the bundle thereby forming a light absorbing layer.  
     CONSTITUTION: A bundle of optical fibers are sealed in a glass tube, and a metal or metal compound of nickel nitrate or silver nitrate is injected in the form of powder or liquid into the clearances of the fiber bundle and is heated together with the optical fibers. The heating causes the metal or metal compound to evaporate or to evaporate after decomposition. The vapor thereof is maintained in the tube and this vapor sticks on the optical fiber surfaces whereby the optical absorbing layer is formed. These enable the surfaces in the clearances of the fiber bundle to be completely coated and enable the light leakage from the optical fibers to be surely absorbed and prevented.

Abstract: PURPOSE:To reduce the installation space and reduce the number of the parts of an air-cooled fuel cell system by installing an even number of cells around one blower and isotropically connecting the blower to the cells by means of ducts so as to form air circulation paths. CONSTITUTION:In an air-cooled fuel cell system, which is provided with one blower (Bw), air circulation paths are partially used in common. Four cells (FC1-FC4) are placed in different quadrants determined by the X axis and the Y axis intersecting at an original point at which the blower (Bw) is installed. Owing to the above constitution, the cells (FC1-FC4) can be placed in high density. Besides, since the cells (FC1-FC4) and air flow paths are placed isotropically, the balancing of air circulation is facilitated. The exhaust ducts of the cells (FC1-FC4) are connected to a common exhaust path (B-C) and the air supply ducts of the cells (FC1-FC4) are connected to a common air supply path (b-c). In addition, the central points (A) and (a) of the common exhaust path (B-C) and the common air-supply path (b-c) are connected by a common path (A-a) having the blower (BW) so as to form an air circulation path.

Abstract: PURPOSE:To correctly detect the position of a converging lens by arranging a lens position detector in a position and a direction not influenced by diffracted light reflected from the surface of an information recording medium. CONSTITUTION:The detection of the position in a tracking direction of the converging lens 1 against an optical head is performed by detecting light from light source parts 23A, 23B reflected by reflecting parts 22A, 22B of a holding part 2 to hold the converging lens 1 by light detecting part 24A, 24B. Here, the light source part 23A, the light detecting part 24A, and the light source part 23B, the light detecting part 24B are arranged respectively so as to be parallel with the optical path of the diffracted light reflected from the recording medium surface. Besides, the LED parts of the light source parts 23A, 23B are installed at the outer sides of the lens, and the light detecting parts 24A, 24B are installed at inner sides. Accordingly, the diffracted light reflected from the recording medium surface is reflected toward the outside of the converging lens 1. Thus, the diffracted light can be made not to exercise influence upon the light detecting parts 24A, 24B, and the position of the converging lens 1 can be correctly detected.

Title: Apparatus for treatment with activated gas
Inventor: YAMAMOTO EIICHI
IPC: C08J7/00
Filed: 1980-06-26
Abstract: PURPOSE:To enable the inner surface of molded articles such as containers, tubes, etc. to be uniformly treated, by a method wherein when a material to be treated, approaches the injection port of an activated gas, the gas is injected, said material being held by arms radially protruded from a rotating shaft. CONSTITUTION:A synthetic resin molded article 14, e.g. in the form of a bottle, is placed on a holding member 15 above a horizontal holder 16 within a reactor 9. A rotating shaft 12 is rotated to bring about a predetermined vacuum within the reactor 9 by means of an exhaust tube 17 connected to a pressure-reducing apparatus. While introducing gas from a gas-introducing pipe 10 into a plasma generator 5, the gas is irradiated with microwave under a predetermined vacuum to activate the gas. The gas is jetted via a gas-transporting pipe 10 from an injection port 11. When the bottle approaches the injection port 11, the activated gas is blown into the bottle to treat the inner surface thereof. Since the molded article 14 is continuously or intermittently rotated within the reactor 9, the inner surface can uniformly be treated and a plurality of molded articles can be treated at a time.

At the time of injection, the needle base 32 of an injection needle 3 covered with a needle cover 33 is fitted in a needle base fit-in part of the support member 7, and after that, the needle cover 33 is removed to perform piercing. After use, when the outer cylinder 4 and the sleeve 6 are rotated in the reverse direction while they are drawn, the edge part slides along the side surface of an arch-like plate-like part of the locking means 64 and a second surface of a raised part to release locking.  Subsequently, the sleeve 6 is slid toward the tip to completely surround the injection needle 3 at the elongation position to be locked irreversibly at the locking part of the support member 7.

Title: Sheet thickness-controlling method in extrusion molding machine
Inventor: OTA TOMOYA
IPC: B29C48/08
Filed: 1990-04-03
Abstract: PURPOSE:To enable the thickness of a sheet to be controlled with high accuracy, while the work of monitoring and controlling the measured data of sheet thickness by an operator is made unnecessary by providing the means which corrects the relation of a plurality of lip pieces to the width direction-measuring position by a sheet thickness-sensor. CONSTITUTION:A peak value-computing device 31 carrys out its calculation, based on a preliminarily determined formula, and simultaneously calculates the peak value in the change of sheet thickness by the detecting signal from a sheet thickness-sensor 21. A correcting computer device 32 outputs the correcting value in relation to neck-in amount to a sheet thickness-drive controlling device 17 on the basis of the output from said peak value-computing device 31, and simultaneously returns the correcting data of the neck-in amount to the peak value-computing device 31. A correcting device 30 is composed of the peak value-computing device 31 and the correcting computer device 32. If a die is shifted into width direction, the relation of each lip piece to the width direction-measuring position of the sheet thickness- sensor is also shifted, but for this shift, the treatment which corrects the neck-in amount is repeated so that the shift between positions of thickness change detected in relation to two preliminarily determined lip pieces and between two correcting calculated values, is removed.
