Title: Engine with turbocharger
Inventor: HANDA OSATOSHI
IPC: F02B37/18
Filed: 1985-03-06
Abstract: PURPOSE:To rapidly increase temperature in a turbine inlet and suppress generation of a turbo lag, by closing a flow regulating valve provided in an atmospheric opening passage while opening a one way type valve provided in an exhaust communication path and supplying air to an exhaust passage in the upstream of a catalyst, when an engine is accelerated. CONSTITUTION:One passage 31b, branching from a delivery passage 31a of an air pump 25 in a three way type pipe 31, communicates with an inlet side or the like of the air pump 25, and the passage 31b provides on its half way a flow regulating valve 37. While the other passage 31c, branching from the delivery passage 31a, communicates with a supply port 39 opened to an exhaust passage 3 in the upstream of a catalyst 19, and the passage 31c provides on its half way a one way type valve 41 allowing air to flow only in a side of the exhaust passage 3. And when a negative intake pressure is generated with the small opening of a throttle valve 13, a diaphragm valve 47 in an actuator 45 is pulled opening the flow regulating valve 37. On the contrary, if the intake pressure increases to the atmospheric pressure by opening the throttle valve 13 for acceleration, the flow regulating valve 37 is closed while the one way type valve 41 is opened by the delivery pressure of the air pump 25.

Title: Burning-preventing agent for molding sand for mg alloy casting
Inventor: TSUKUDA MAKOTO
IPC: B22C1/06
Filed: 1980-04-01
Abstract: PURPOSE: To burning-preventing agent for molding sand for Mg alloy casting which comprises containing PE powder of a specified grain size range as an effective component, and which is extremely high in burning preventing effect and can prevent blowhole defects.  
     CONSTITUTION: PE powder of 100W270 meshes is compounded as a burning-preventing agent in the 2W10% range with molding sand for Mg alloy casting. When, for example, a phenolic self-hardening mold is manufactured by using this molding sand, its burning preventing effect is extremely high as compared to the usual burning-preventing agents. Since this burning-preventing agent is powdery and granular and has no possibility of reacting with sodium silicate, it is compounded at a sufficient amount with a CO 2  type mold, whereby high burning-preventing effect is obtained. Further, when this burning-preventing agent is adapted to a self-hardening mold, PE is first decomposed by the heat of molten metal and forms a protecting film on the surface of molten Mg; therefore, blowhole defects are prevented.

Title: Production of synthetic resin molded product
Inventor: INADA YOSHIHIRO
IPC: B29C45/56
Filed: 1991-03-08
Abstract: PURPOSE:To prevent the deformation or positional shift of a decorative sheet due to an injected molten resin by fixing the decorative sheet at the time of injection molding by a holding mechanism and making the injection pressure of the molten resin extremely low. CONSTITUTION:An extremely thin decorative sheet 7 is arranged to a cavity 3. Subsequently, a mold 1 is closed until it reaches a state immediately before a full-closed state and the decorative sheet 7 is fixed by a press pin 5. After a molten resin 8 is injected in the cavity 3 under low pressure, the mold 1 is fully closed to press the molten resin 8 in the cavity 3. As a result, the generation of difference in level in a design surface is prevented by injection molding and an arbitrary shape can be molded and, since the decorative sheet 7 is fixed by the press pin 5 at the time of injection molding and injection pressure is extremely low, the extremely thin decorative sheet 7 is used to contribute to wt. reduction and cost reduction.

Abstract: PROBLEM TO BE SOLVED: To dispence with an external power supply by fiting a wavelength shift member to a light incident face of a solar battery, shifting the radiation passing through the member to a visible light area, thereby alloying, the battery to generate electricity by means of visible light. SOLUTION: A wavelength shift member 2 is mounted on the light incident face of a solar battery 1. The radiation such as gumma ray passing through the member 2 is shifted to a visible light area by the member 2 and then making it reach the battery 1. The battery 1 produces electricity by menus of visible light. As the material of the member 2, synthetic resin such as cesium iodide or plastic is most suitable. Since cesium iodide is heat resistant and effective to the radiation generating decay heat. The synthetic resin such as plastic has a radiation resistant characteristic and can be set freely in its width and the like, and also is convenient for controlling the wavelength shift characteristics. In this way, through a simple and inexpensive constitution, an external power source can be made unnecessary.

IPC: G06F17/28
Filed: 1990-02-23
Abstract: PURPOSE:To attain the display/specification of a translation range even when a display area is small by specifying the translation range to a recognized character string. CONSTITUTION:This electronic translator has an image input means 1, a character recognizing means 2, a translation means 3, and an information means 4.
