Title: Distributed reflection laser
Inventor: KATSUTA HIROHIKO
IPC: H01S5/16
Filed: 1986-03-24
Abstract: PURPOSE:To lessen the reflectivity at the terminal surfaces of the diffraction grating and to improve the wavelength selectivity by a method wherein the plane forms of the terminal parts of the external waveguide layer are formed into a tapered form and moreover, a buried layer is provided in such a way as to cover all the side surfaces of the external waveguide layer. CONSTITUTION:In a distributed reflection type laser which is constituted by forming an active waveguide layer consisting of a gain medium and an external waveguide layer having a diffraction grating on a semiconductor substrate, the plane forms of the terminal parts Ya' and Yb' of external waveguide layer regions Ya and Yb are formed into a smooth tapered form. Moreover, the external waveguide layer regions Ya and Yb are formed into a constitution wherein their points are embedded with a buried layer 31 and are not exposed to the outside. that is, this constitution is formed into a constitution, wherein with the terminal parts of an external waveguide layer 25 formed into a tapered form, the side surfaces of the external waveguide layer 25 are all buried in a buried layer 31. As the terminal parts of the external waveguide layer are formed into a tapered form, the reflectivity at these parts is reduced, whereby the internal reflection is remarkedly decreased and the wavelength selectivity is improved.

Title: Developing device
Inventor: YANAGI KENZO
IPC: G03G15/08
Filed: 1988-03-17
Abstract: PURPOSE:To stabilize a toner supply by dropping a toner by a vibration of a sheet-like member even if the inclination of a toner tank is below an angle of repose of the toner by providing the sheet-like member filliped by a mixer in a developing device. CONSTITUTION:An angle at which a toner 6 drops down naturally is >=45 deg., but when the bottom face of a toner tank 5 is set to >=45 deg., the capacity of the toner tank 5 of a developing device becomes smaller. Therefore, a sheet-like member 4 being a vibrating means is contained on the bottom face of the toner tank 5 of the developing device. That is, when a mixer 3 being a stirring means rotates in the direction as indicated with an arrow, this sheet-like member 4 is filliped, and vibrated. As long as the stirring means 3 rotates, this vibration is repeated. In such a way, the toner 6 always drops down to the lower part of the toner tank 5 and the toner 6 can be supplied stably.

Title: Core and lap wound body with long size body
IPC: B65H75/10
Filed: 1992-03-23
Abstract: PURPOSE:To provide a core which is used for winding up a product whose length expands and contracts greatly after it is wound and whose winding diameter is elastic. CONSTITUTION:A sheet-like material 1 such as corrugated board is curved in such a way that its fringe sections are overlapped to form a cylindrical shape, and tongue pieces 2, 2 are protrusively provided in one of the fringe sections which is parallel with its axis. A part of the tip of the tongue pieces 2, 2 is inserted into notches 3, 3 which are provided in the other fringe section to form a core. Thus, even if a winding diameter expands and contracts due to expansion and contraction of a wound-up long size body, stress does not occur and the product and core are not deformed because the tongue pieces 2, 2 slide in the notches 3, 3 and the diameter of core expands and contracts.

Title: Leak prevention device of shaft seal portion
Inventor: TACHIKAWA KATSUJI
IPC: F16J15/00
Filed: 1982-04-21
Abstract: PURPOSE:To automatically prevent the fluid leak from a shaft seal portion while a pump is at halt by controlling a clearance between a piston and a sleeve fitted to a shaft by means of a pump discharge pressure. CONSTITUTION:During a pump operation, a discharge side pressure higher than that of a suction side flows into the right side opposite to an impeller of a cylinder 5 through a pressure guide pipe 10 by means of the pumping-up action of the impeller 4, thereby a piston 6 is moved to the left against the force of a spring 7, and a clearance 11 with a sleeve 2 is expanded. On the other hand, when the pump is stopped, the impeller 4 ceases its pumping-up action, the suction pressure and discharge pressure of the pump become equal, thus pressures applied to both sides of the piston 6 become equal. Accordingly, the piston 6 is moved to the right by means of the force of the spring 7 and is brought into close contact with the left end face of the sleeve 2 to close the clearance 11. Therefore, the inside of the pump is cut off from the atmosphere, and the fluid in the pump is prevented from leaking into the atmosphere.

Title: Method for predicting breakout in continuous casting
Inventor: TERAMAE YASUTAKA
IPC: B22D11/16
Filed: 1985-03-29
Abstract: PURPOSE:To predict precisely breakout by excluding factors by a change of casting speed from the measured temp. values of the wall in a mold and making the judgement for prediction on the basis of the relative temp. determined from the ratio between the temp. at the prescribed measuring point and the entire measuring point. CONSTITUTION:The temp. Ti of the inside wall of the mold is measured by the plural temp. measuring elements provided in the mold of a continuous casting device. The factors by the change of the casting speed are excluded from the measured temp. Ti in accordance with the preliminarily determined relation between the temp. at each measuring point and casting speed. The ratio between the temp. T3 at the prescribed measuring point and the entire average temp. is determined as the relative temp. F(T3). The breakout is predicted when the relative temp. F(T3) deviates from the preset upper and lower limit values A, B. The precise prediction of the breakout is thus made possible.

Title: Adhesive
Inventor: ABE MASAYUKI
IPC: C09J5/00
Filed: 1983-04-15
Abstract: PURPOSE:To improve adhesive strength, by applying an adhesive containing a substance in powder which is harder than adherends and moving the adherends relatively until solidification of the adhesive so that the adherends may be roughened on the surface. CONSTITUTION:A substance in powder harder than one or both of two adherends (e.g. glass powder) is mixed into an adhesive. The adhesive is applied to adhesive surfaces of the two adherends and they are moved relatively with the adhesive interposed between them until the adhesive solidifies. The substance in powder with higher hardness roughens the surfaces of the adherends with lower hardness, leading to strong adhesion of the two adherends. Thus pretreatment of adherend such as surface grinding can be omitted.

Title: Fuel reformer
Inventor: NAKAGAWA ISAO
IPC: H01M8/06
Filed: 1990-03-16
Abstract: PURPOSE:To uniformly hold a catalyst bed in a reaction tube even when a reforming catalyst is powdered by horizontally inserting a catalyst supporting plate having many holes each having a diameter not permitting the passage of the catalyst into the plural sites of the catalyst bed.

Title: Operation of optical potentiometer
Inventor: SATO MASUJI
IPC: H01L31/14
Filed: 1989-03-20
Abstract: PURPOSE:To enhance a responsive property to generate a photoelectric current when a light spot is actually applied by a method wherein a periphery of a light-spot irradiation position is irradiated in advance with very small bias light. CONSTITUTION:When an optional potentiometer composed of a triode element which is constituted of a resistance film 1, a photoconductive film 13 and electrode films 15 (15A, 15B) is operated, a width of a light spot A is made larger than that required essentially. That is to say, when an essentially required spot width is DELTAS, a spot width by this invention is set to kDELTAS. It is sufficient when k>1; however, it is preferable that k=3 to 5. Thereby, both sides of an essential light-spot irradiation point is irradiated with bias light whose width is always (kDELTAS-DELTAS)/2. An irradiation position is subjected to the bias light before it is irradiated with an essential light spot; both a rise responsive property and a fall responsive property are enhanced.
