Title: Fire sensor
Inventor: ASAKINO KUNIHIRO
IPC: G08B17/00
Filed: 1987-07-10
Abstract: PURPOSE:To detect the location of fire occurrence by providing plural pieces of thermal sensors constituted of a junction surface where the optical axis shifts due to temperature variation in series connection to an optical fiber, and detecting the variation in the reflection loss of a laser beam by the thermal sensor. CONSTITUTION:The thermal sensors a A1-A4 are constituted in a manner that the optical fiber is cut and the cut ends brought into contact with each other so that the optical fiber axis will shift at the splicing part by the variation of temperature. These sensors A1-A4 are arranged in series to one piece of optical fiber B0. An electric pulse is converted to a pulse-shaped optical signal, which is made incident on the fiber B0. The incident beam is reflected by the thermal sensors A1-A4, the amount of loss of the beam is measured, and the loss amount is A/D-converted then stored in a digital memory. In the memory, the data of beam-loss amount at a normal time is separately stored. In case of a fire, the beam loss detected by the thermal sensor in the location of the fire increases, and this increased loss is compared with the data at normal time, and the location of the fire occurrence is thus detected.

Title: Evaporation treating method for foaming liquid
Inventor: SAGAWA HIROSHI
IPC: G21F9/08
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To establish a method for evaporating a foaming liquid in which the time required for treatment is shortened, and the foaming is suppressed by heating a liquid to be treated to about its boiling point, reducing the output of a heat source over a prescribed time to minimize the temperature difference between the heat source and the liquid to be treated, and then raising the output of the heat source to evaporate the liquid to be treated. SOLUTION: A heating is performed while shortening the temperature raising time to boiling start by controlling a dipping type heat source output, and the output of the heat source is then reduced just before foaming to bring the temperature of a foaming liquid to be treated close to the heat source, so that evaporation is started without foaming. Namely, detergent drain water 1 to be treated is put in an evaporator 2, and an electric heater 3 is dipped and set therein.  The drain water 1 is circulated by a concentration pump 4, the output of the heater 3 is set to 100% when evaporation by the evaporator 2 is started, the drain water to be treated is heated to 95 deg.C, the output of the heater 3 is lowered so that the drain water can be evaporated without foaming, the output of the heater 3 is gradually raised, and the generated steam is condensed in a condenser 5, and taken as distilled water 7 while a non-condensed gas 6 is exhausted.

Abstract: PROBLEM TO BE SOLVED: To enable the simultaneous sepn. of plural carriers from wavelength divided multiples light with simple constitution by using an apparatus which has first to third lenses and an angle dispersion device and receives input light of respective wavelengths within a continuous range of wavelengths. SOLUTION: The first lens 200 collimates input light when viewed laterally. The lens does not possess the effect of a lens when viewed from front. The second lens 202 receives the input light from the first lens 200 and condenses the input light when viewed laterally. The lens does not possess the effect of a lens when viewed from front. The third lens 204 receives the input light from the second lens 202 and collimates the input light when viewed from front. The lens does not possess the effect of a lens when viewed laterally. The light from the third lens is received in a virtually imaged phased array(VIPA) 76.

Title: Power gear
Inventor: TOMOKIYO KOICHI
IPC: F16H1/28
Filed: 1988-07-09
Abstract: PURPOSE:To simplify its construction so as to utilize it in saving energy, by doubling power transmitted from its power transmission gear side by means of a gear which is rotated thereabouts to be removed and which is utilized as a lever, and transmitting the power thus doubled by the same number of revolution to a gear having the same diameter as that of the power transmission side. CONSTITUTION:When force is exerted on an A point on a gear 2 to be utilized as a lever in its right and left directions as indicated by an arrow,then approximately twice as much the force is exerted on a gear 1 on the side of its output from a mounting shaft 4 while a gear 3 which is engaged with a B point is utilized as a lever, and the gear 1 on the side of its output is thereby removed as much as the gear 2 to be utilized as a lever is rotatingly removed; when force is exerted thereon from the gear 1 on the side of its output, the force is equally distributed to the A and B points of the gear 2 to be utilized as a lever from the mounting shaft 4. This may be identified with the fact that when force is exerted on the center of a bar, the panel points supporting both ends thereof have half the force distributed thereto, respectively. It is thus simply constructed and manufactured in a smaller size than those of any other transmission gears now in use; moreover, it can be used in many ways for energy-saving measures.

Title: Tape cassette and method and mold for molding tape cassette
Inventor: SASAKI NOBUYOSHI
IPC: G11B23/113
Filed: 1988-07-11
Abstract: PURPOSE:To obtain a tape cassette which has no cloudy part in its transparent widow and no inferior part in the joining section between the main body and window section by eliminating the influence of the resin gas produced when the window section is molded of the 2nd resin by taking the resin flowing route at the time of molding the main body of the 1st resin into account. CONSTITUTION:In the course of producing a cassette half body 2, a molding cave is produced by butting a cavity 11 and core 12 against each other and bringing a core 13 upward. Then a resin is injected into the front face of a main body 3 through gates 141 and 142. The resin injected through a gate 143 is led into the space between the core 13 and rib 16 by a wall 16 and fills the core 13 section from the rear section. The gas produced from the resin escapes through the rear joining section of the molding boxes 11 and 12. Before the resin starts to harden, the core 13 is lowered and the 2nd transparent resin is injected into the window section forming cave section from a central gate so as to secondarily mold a window 4. At the time of molding the window 4, projecting ribs 15a and 15b eases the resin injecting pressure so that the internal distortion and deformation of the primarily molded can be prevented. After the resin hardens, the molding boxes are removed. When such constitution is used, corrosion of the core 13 by the resin gas, a cloudy part in the window 4, and inferior joining between the main body 3 and window 4 can be prevented.
