Filed: 1989-06-01
Abstract: PURPOSE:To achieve immediately, directly, clearly and precisely a state of molding even if the operator is not a skilled technician, by making use of a tablet where sections provided repeatedly at fixed intervals are colored in separate colors. CONSTITUTION:A polyethylene tablet 11 premolded in high quality is cut into round slices, red and black paints are applied thin to a circular section in a semicircular form at every 90 degrees, the slices are piled upon one another so that a color division is not slid and confronting two positions on the outer circumference are fixed by performing easily thermal welding. The tablet 11 is used for constitution of a mold type, transfer molding is performed by injection through a gate part of a head part of molding 3 and a colored state at a principal section XX-ZZ of a molding 3 with the final mold is examined. In the case where any of the section is colored intermittently with the red and black in the semicircular form at every 90 degrees and the same is in almost similar figures with the color of the section 21 of the tablet 11, with this construction, molding is performed uniformly and in axis symmetry.

Title: Device for changing wavelength of light
Inventor: TANIUCHI TETSUO
IPC: G02F1/37
Filed: 1984-07-05
Abstract: PURPOSE:To change easily the wavelength of light by forming a light guide in a single crystal substrate of lithium niobate by an ion exchange method, introducing light having a fundamental wave into the light guide from one end, and taking out harmonics radiating in the substrate. CONSTITUTION:A light guide 4 is formed in a single crystal substrate 3 of lithium niobate by an ion exchange method. Light P1 having a fundamental wave is introduced into the light guide 4 from one end, and harmonics P2 radiating in the substrate 3 are taken out. When Fabry-Perot resonance is caused by sticking reflecting films 8, 8' to both ends of the light guide 4, the output of the harmonics P2 is increased. Thus, the wavelength of light is changed easily and efficiently.

Abstract: PURPOSE:To produce a nonfermentable sugar containing highly hygroscopic isomaltose as a main component, by treating a maltose-containing liquid with transglucosidase, thereby removing the existing glucose, etc. having poor hygroscopicity. CONSTITUTION:A liquid containing nonfermentable sugar is prepared by treating a maltose-containing liquid with transglucosidase, and the obtained sugar liquid is added with glucoamylase to decompose the existing maltose and maltooligosaccharide to glucose. The resultant mixture composed of nonfermentable sugar and glucose is passed through an alkali metal-type strongly acidic cation exchange resin or an alkaline earth metal-type strongly acidic cation exchange resin to separate the nonfermentable sugar fraction from the glucose fraction. A nonfermentable sugar composition containing >=70% nonfermentable sugar can be produced by this process.

Title: Safety device for hot water temperature sensor of water heater
Inventor: OKADA YASUHIRO
IPC: F23N5/14
Filed: 1986-06-17
Abstract: PURPOSE:To provide a safety device for hot water temperature sensor which, when there is a malfunction in the hot water temperature, detects the malfunction of the hot water temperature sensor, and is not adversely affected by a gas flow rate controller or the ambient temperature of the hot water temperature sensor. CONSTITUTION:Under normal conditions, a voltage is applied to a resistor 9 by a current flowing through a resistor 17, a hot water temperature sensor 2 and the resistor 9. If there is a failure of the hot water temperature sensor 9 in which it remains open Ve=OV, and the output of a comparator 14 becomes 'Hi'. If the water heater starts its operation, and the flame detection causes the 'Hi' signal to be transmitted to an AND circuit 15, the output of the AND circuit 15 becomes 'Hi', which then causes a burning control circuit 6 to finally perform a burning prohibition action. Therefore, in winter seasons, even if the resistance of the hot water temperature sensor 2 is large, and the output from the comparator 14 is 'Hi', the output of the AND circuit 15 does not become 'Hi', and so, the burning control circuit 6 does not assume the burning prohibition action. If the hot water temperature sensor 2 experiences a failure in which it remains open, the burning is prohibited only when the output of a flame sensor 16 comes 'Hi'.

Title: Method for reinforcing treatment of fusion-fixing connection part of optical fiber
Inventor: MATSUMOTO MICHITO
IPC: G02B6/24

Abstract: PURPOSE:To keep the mechanical strength for a long time, by coating a fusion-fixing connection part, where a pair of optical fiber end parts are butted to each other and are fusion-fixed, with a gas-permeable film after subjecting this fusion-fixing connection part to the surface teatment with a corrosive solution which dissolves optical fibers. CONSTITUTION:Optical fibers 1A and 1B have coating layers eliminated from end parts 2A and 2B and are butted and are fusion-fixed by arc discharge or the like to form a fusion-fixing connection part 5. A corrosive solution 6 such as a hydrofluoric acid which dissolves optical fibers is stored in a liquid bath 7, and the connetion part 5 between optical fibers 1A and 1B is soaked in the liquid bath 7 and is subjected to a required reinforcing treatment. The connection part 5 subjected to the reinforcing treatment is taken out to the outside of the liquid bath 7 and is washed. High polymer materials having a high gas permeability such as a thermosetting silicone resin are applied to the outside circumference of the connection part 5 including end parts 2A and 2B, and a film 8 formed by this aplication is subjected to the heat treatment by a cylindrical heater 9. Thus, the mechanical strength of the connection part is improved, and adhesion of dust or the like is prevented to connect optical fibers stably for a long time.

Title: Valve arrangement with five valves
Inventor: SUZUKI HIROMI
IPC: F01L1/26
Filed: 1990-05-30
Abstract: PURPOSE:To nearly equalize the intake air quantities from three intake ports to substantially increase the total intake air quantity and to increase output in three intake valves of a valve arrangement with five valves by installing the three valves to be tilted at relatively large included angle, and forming intake ports so that they are gently curved. CONSTITUTION:Two inside intake valves 7a, 7b are installed tilted at an included angle theta2 slightly smaller than the included angle theta1 of exhaust valves 8a, 8b, and intake ports 16a, 16b are formed to be gently curved. An outside intake valve 7c is installed to be tilted at an included angle theta3 slightly larger than the included angle theta2, and an intake port 16c is formed to be gently curved. The three intake valves 7a - 7c are simultaneously opened. Since the three intake ports 16a - 16c are formed so that they are gently curved, each intake port sucks nearly an equal quantity of intake air in a state where air-sucking resistance is small, and thus such about three times the intake air quantity that one valve sucks. The air sucking efficiency can thus be substantially improved.
