Title: Smoke responding device for automobile
Inventor: MORIYA MITSUTOSHI
IPC: B60H1/00
Filed: 1982-09-23
Abstract: PURPOSE:To prevent an air conditioner from responding so frequently, by detecting the presence of smoke in a way of comparing a photoelectric element signal commensurate to the smoke with the reference value, while controlling the air conditioner to stay in a specified state by the time of the specified delay time after changing from a yes to a no. CONSTITUTION:A smoke detecting device 10 attached to a ceiling inside a car room and composed of luminous and light receiving elements 11A and 11B outputs a signal Vs commensurate to smoke density, and when the density goes beyond a reference value Vd, an output level of a comparison device 14 is varied, turning on level convertion circuits 27 then 22 a bit later in succession, and an electric motor 30 is kept in a state of being turned on whereby operates an air cleaner device. And, when the smoke density falls below the reference level, the level converter 27 comes into an on state but the level converter 22 keeps the on state for some time, for example, for 20sec long by means of a delay device 15. Therefore, when the signal Vs is reversed again within this delay time, the delay device 15 repeats the delay motion from the outset so that the electric motor 30 continuously operates for considerable time. Thus an air conditioner is prevented from varying its conditions so frequently.

Title: Production of slurry of ceramic green sheet
Inventor: FURUKAWA SANEHIRO
IPC: H01M8/02
Filed: 1987-07-02
Abstract: PURPOSE:To enable the production of the titled constantly uniform slurry resistant to denaturation over a long period, by mixing ceramic powder with an unsaturated fatty acid ester, a binder, a plasticizer and a solvent to form a slurry. CONSTITUTION:The slurry of the objective ceramic green sheet can be prepared by mixing ceramic powder with a dispersing agent, a binder, a plasticizer and a solvent using an unsaturated fatty acid ester as the dispersing agent. When the carbon number of the fatty acid of the unsaturated fatty acid ester is >=25, the synthesized ester is white semisolid or wax at or about normal temperature. On the other hand, a fatty acid having a carbon number of <=12 gives an ester having low viscosity and poor dispersion capability at or about normal temperature. Both esters are inadequate to be used as the dispersing agent. When the alcohol has a carbon number of >=8, the synthesized ester has low solubility in a solvent in the preparation of slurry to deteriorate the dispersing capability and the ester is also inadequate as the dispersing agent.

Abstract: PURPOSE:To form a helically formed part in which no flute-like recess generates and which at the same time has high bonding strength between molding materials, by a method wherein the molding material is wound round a rotating take-up shaft just after being extruded in a specified shape in order to cool and solidify. CONSTITUTION:Molding material 2, in the cross-section of which the breadth E of the surface 10 directly winding onto the surface of a take-up shaft is made smaller than the breadth F of the outside surface 11, is continuously extruded through the orifice 1 of an extruder. Just after being extruded, the molding material 2 is wound up round the take-up shaft 3 rotating at the position nearly normal to the molding material 2. The taken-up molding material 2 is immediately cooled and solidified. At this stage, various kinds of stresses are applied to the molding material 2, resulting in widening the surface 10 contacting with the take-up shaft 3 laterally and, on the contrary, shrinking the breadth of the outer peripheral surface 11 which does not contact with the take-up shaft 3. As a result, no flute-like recess generates in a formed part and at the same time the bond area of the joining surfaces 14 of the molding material 2 among one another becomes larger and accordingly, the bonding strength between the molding materials is enhanced.
