Title: Manufacture of building board
Inventor: MATSUDA HIROSHI
IPC: B32B33/00
Filed: 1982-02-27
Abstract: PURPOSE:To obtain the titled board exhibiting an effect similar to that of natural tiles, by erecting a beltlike film of thermoplastic synthetic resin having low heat resistance on a base plate having high heat resistance to border the base plate, pouring powder paint inside the frame, and heating said paint. CONSTITUTION:A beltlike film 2 of thermoplastic synthetic resin having poor heat resistance is stood on a base plate 1 having high heat resistance, to form an annular bordering part 3. Thereafter, powder paint is poured inside the bordering part 3, and then the base plate 1 is charged in a heating oven and heated therein. As a result, the powder paint melted by heat is let flow out over the bordering part 3 and formed into a naturally rounded state at the edge of a tile-like part, so as to exhibit an effect similar to that of real tiles.

Title: Copper alloy for metallic mold for molding plastic
Inventor: KURAMOTO YUKICHIKA
IPC: C22C9/00
Filed: 1986-02-17
Abstract: PURPOSE:To provide superior strength and transferability to a Cu alloy without adding Co by adding specified amounts of Be, Fe, Ni and Si to Cu. CONSTITUTION:The composition of a Cu alloy for a metallic mold for molding plastics is composed of, by weight, 1.5-2.5% Be, 1.5-2.5% Fe, 0.5-1.5% Ni, 0.5-1.5% Si and the balance Cu. The alloy contains Fe as a grain refining element in place of Co. When the Cu alloy is used, the polished surface of a metallic mold is made free from unevenness due to difference in level and no tarnished layer is formed. Since the amount of Be is small, the cost of materials is reduced.

Filed: 1989-02-10
Abstract: PURPOSE:To prevent particles from adhering by providing a photosensor which lets reflected light of a laser light with a flow cell be incident to judge the presence of a liquid within the flow cell based on a size of an output of the photosensor. CONSTITUTION:Intensity of reflected light R varies according to the presence of a flow cell 3 and the presence of a liquid to differentiate an output voltage of a photosensor 6. When the flow cell is filled with a liquid, the intensity of the reflected light R is low while it increases when the flow cell is not.

Title: Control system of reluctance motor
Inventor: KURAKAKE MITSUO
IPC: H02P23/00
Filed: 1986-02-17
Abstract: PURPOSE:To supply currents of both positive and negative polarities flowing in winding of each phase, by a method wherein period of processing signal during digital indication of detection signal of a resolver is made twice of that of MSB in bit indication. CONSTITUTION:Output waveform D2 with period being twice of that of MSB is obtained from J-K flipflop. Where MSB is bit value in maximum digit when sinusoidal wave obtained by a resolver is indicated in bits, and waveform D1 is pulse of 1/2 period of MSB. In such constitution of the resolver signal, when both the MSB and the waveform D1 are in rising state, clockwise rotation is produced as shown in solid line, and even if the current polarity is inverted at the midway, the rotational direction does not vary until next rising of both MSB and D1. On the contrary, in counterclockwise rotation, when both MSB and D1 are in falling state, counterclockwise rotation is produced, and even if the current polarity is inverted at the midway, the rotational direction does not vary. Consequently, currents can be divided in positive and negative polarities with respect to double period of the MSB.
