Title: Foamed flooring material for interior use and production thereof
Inventor: AKIMOTO YOSHIKI
IPC: C04B33/16
Filed: 1990-04-17
Abstract: PURPOSE:To obtain a non-water-absorbing and easily cleanable foamed flooring material for interior use, having light-weight, excellent heat-insulation and freeze resistance by mixing clay, feldspar and silicon carbide at specific weight ratios, forming the mixture and firing the product to effect the foaming and sintering of the material. CONSTITUTION:The objective foamed flooring material for interior use can be produced by mixing 40-10 pts.wt. of clay, 60-90 pts.wt. of feldspar and <=1 pt.wt. of silicon carbide, forming the mixture and firing at 1200-1300 deg.C to obtain a foamed and sintered material. The clay used in the present material is a non-foaming clay which does not foam by firing. Since the obtained foamed flooring material has closed cell structure, it is free from water-absorption. As the material is free from glazing layer, the slipping accident can be prevented. It has comfortable feeling free from chilling feeling because of its high heat-insulation.

Filed: 1979-08-08
Abstract: PURPOSE:To improve the efficiency of an electromagnetic reciprocation by a construction wherein controllers providing quiescent time among the starting terminals and end terminals of voltage alternately conducted to two electromagnetic coils are mounted to the coils. CONSTITUTION:An electromagnetic reciprocating driving device is formed in such a manner that alternating currents are alternately conducted to two electromagnetic coils 7, 7', and a movable magnetic material is reciprocated by the electromagnetic force of the electromatnetic coils 7, 7'. Devices which rectifiers 9, 9', whose polarity is each directed in the reverse direction, and constant-voltage diodes 10, 10' are made up are used as controllers 11 for conducting the electromagnetic coils 7, 7', and quiescent time is given to the starting terminals and end terminals of voltage applied to each electromagnetic coil 7, 7'. Thus, an offset of the electromagnetic force of each electromagnetic coil 7, 7' can be eliminated because a condition that is conducted to both electromagnetic coils 7, 7' is not generated when conduction is shifted to the conduction of the electromagnetic coil 7' from the conduction of the electromagnetic coil 7.

Title: Transmission and reception system of television video signal
Inventor: ONOZATO MASASHI
IPC: H04N7/16
Filed: 1984-05-22
Abstract: PURPOSE:To allow a limited subscriber only to attain reception by applying scrambling to the order of a video signal at the transmission side, transmitting the result and applying descrambling it at the reception side. CONSTITUTION:Switches 21-24 are transmission/reception changeover switches and Fig. shows the transmission state. When an address to read a video image data of a memory 3 changes according to, e.g., Table (a) by a V address converting circuit (scramble circuit) 17 at the transmission side, the order of the video image at the transmission side output is at random as shown in Fig. (b). Further, in this case, in order to prevent that the continuity of the burst is lost, a burst is inserted at the output side. In the reception side (the position of the switches 21-24 is opposite to the position shown in Fig.), the order of the random video image is inverted by a V address converter (descramble circuit) 18. Moreover, a flag detection circuit 11 detects a flag and gives it to a write V address generator 9 when no write address correction is executed at the reception side.

CONSTITUTION: When driving air is supplied in a cylinder 14, a piston 21 is moved in one direction, and a switching member 55 abuts on one end of a switching driving rod 51. When springs 62, 63 are deflected and shortened in a reciprocating movement direction by a second movable body 65 which is moved reciprocation on the other end of the rod 51 in association with one way movement of the piston 21, the position of the switching member 55 is restricted on the other end of the rod 51, and the switching member 55 is moved in an opposite direction relatively with the piston 21 which is moved in one direction. At this time, excessive shock is not applied by deflection of the springs 62, 63 at the time of opening/closing of switching valves 35, 45.  The switching member 55 is forcibly sucked in the opposite direction by magnets 71, 72 of the piston 21, and thereby, the switching valves 35, 45 can be switched rapidly. It is thus possible to prevent deformation and breakage of the switching valve, and also quarantee safety a long-term operation.
