IPC: B28B7/34
Filed: 1989-04-27
Abstract: PURPOSE:To form a high performance coating layer having durability by adhering and laminating insulating high strength fiber prepreg on the surface of a metallic panel. CONSTITUTION:Although glass fibers and aramid fibers are shown for insulating fibers, the glass fibers are advantageous in the anti-wearing property and profitability.

Title: Toilet seat
Inventor: YAMADA KENKO
IPC: A47K11/00
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To improve strength by forming a toilet seat from resin specified to to be an Izod with a notch and coating its surface with acid proof and alkali resistant paint. SOLUTION: A resin whose Izod with a notch has 10kg.cm or more in impact strength is used for a toilet seat material. Secondly, a reaction injection molding method which can be molded after a raw material in its liquid state is injected is adopted as a molding method so that no expensive metal is necessary. Thirdly, out of resins which can be molded by the reaction injection molding method, it is preferable to use bridge polymer of cyclic olefin which has low viscosity in its raw liquid state and has strong impact strength in its molded state. The bridge polymer of the cyclic olefin is superior in acid resistance, alkali resistance, and chemical resistance, however, it is easily damaged into a small flaw and easily stained by sticking of excrete dregs so that the surface of the molded material is coated with fluorine based or silicon based acid proof and alkali resistant paint.  This constitution can prevent the toilet seat from being broken by mischief, reduce the weight, and improve durability.

Title: Self-measuring device for clouding point
Inventor: YAGIYUU TOSHIFUMI
IPC: G01N25/04
Filed: 1981-07-08
Abstract: PURPOSE:To automate a device, by a method wherein a forward end of a luminous part and a forward end of a collecting part are positioned in a sample so that, in case the sample is brought to an opaque state, the collecting part can collect light from the luminous part, but in case it is brought to a clear state, it can not collect the light. CONSTITUTION:Aluminous part 4 and a collecting part 5 of a photoelectric detector are mounted to an upper surface of a lid 2 of a sample receptacle, and optical fibers 6 and 7 connected to the parts 4 and 5, respectively, are installed in the receptacle. Forward ends 6' and 7' of the fibers 6 and 7 are positioned in the proximity of the bottom of the receptacle, and the forward end 7' of the collecting part functions such that it is normally prevented from collecting light from the forward end 6' of the luminous part, but in case a sample is brought to an opaque state, the end 7' can collect scattering light thereof. In case a clouding point of an oil product is measured, if the sample attains a given temperature, liquid becomes opaque resulting from education in the sample of a solid matter, i.e., wax, whereby the detection of a point where a given clouding is created causes self-measuring of a clouding point.

Title: Input protection circuit
Inventor: HORIBA YASUTAKA
IPC: H03F1/52
Filed: 1982-06-19
Abstract: PURPOSE:To obtain an input protection circuit preventing destruction of a junction of an input transistor (TR) due to a reverse voltage, by using a TR having the same conduction type as that of an input TR as an input protection element. CONSTITUTION:When a large negative surge voltage is applied to an input terminal 3, if an emitter voltage of the input protection TR14 is more negative than a potential of a ground terminal 6 by a base-emitter forward voltage of an input protection TR14 or over, the input protection TR14 is conductive and charges stored at an emitter of the input TR1 are discharged. When the emitter potential of the input protection TR14 is negative sufficiently more than the potential of the ground terminal 6, the input protection TR14 is saturated, the potential of the emitter of the input TR1 falls down while being kept to almost the same potential as that of the base connected to an input terminal 3 and a reverse voltage is hardly applied to the base-emitter junction of the input TR1, allowing to prevent destruction.
