Title: Torque transmission
Inventor: ISHIKAWA HIROSHI
IPC: B60K17/348
Filed: 1988-10-31
Abstract: PURPOSE:To make it possible to control torque transmission characteristic by forming a cam face so as to vary its difference of elevation in the axial direction, while keeping the total volume of a pressure chamber constant. CONSTITUTION:When an inside rotating member 39 is relatively moved in the axial direction, difference of elevation in the circumferential direction of a cam face 59 slidably contacted with a cam body 79 varies. At moving in the direction of smaller difference of elevation, the speed of reciprocating movement of the cam body 79 decreases. Consequently, flow resistance due to an orifice decreases, the pressing force to the cam face 59 becomes small, and torque transmission becomes small. At moving in the larger difference of elevation, on the contrary, the speed of cam body 79 increases, pressing force increases, and torque transmission becomes large. In such way, difference of elevation of the cam face 59 slidably contacted with the cam body 79 varies by operating axial movement of the rotating member 39, and different torque transmission characteristic can be obtained according to the difference of elevation.

Filed: 1988-10-31
Abstract: PURPOSE:To make a radioactive liquid waste to be able to be concentrated by concentrating water contained in the radioactive liquid waste from a nuclear power facility, with passing through an osmotic vaporization membrane which can pass water and steam selectively. CONSTITUTION:In a concentration tank 1, an osmotic vaporization membrane 2 such as a polyester composite membrane, for instance, which can pass water and steam selectively, is stretched so as to divide the tank into two parts horizontally. In this sort of device, a certain constant amount of a pseudo- radioactive liquid waste 5 is stored in the concentration tank 1. Then the tank 1 is heated up and a temperature of the pseudo-radioactive liquid waste 5 is kept at a constant level. After that, a vacuum pump 10 is operated to pass cooling water through a condensation tank 8 and to keep the condensation tank 8 at a condition of being depressurized and of a lower temperature. By analyzing a condensate 15 accumulated in a condensate storage tank 14 and a refuse liquid remaining in the concentration tank 1 after elapsing a certain constant time, it was known that a concentration of a water solution of a sodium sulfate could be concentrated from 0.2wt% to 20wt%.

Title: Radial white tire
Inventor: NOJI HIKOTOSHI
IPC: B60C13/00
Filed: 1985-12-06
Abstract: PURPOSE:To stabilize the set position of a white rubber by providing a rim cushion rubber on the surface of a bead section continuous to the surface of the white rubber as well as providing an additional bar along a rim check line. CONSTITUTION:In a white tire, a white rubber 1 is disposed between a side wall section and a bead section and a rim cushion rubber 2 is disposed at the place where a rim flange touches it. Therefore, as the white rubber 1 whose modulus is 100% 1/2 in comparison with the rim cushion rubber 2 is apt to be flowed upon vulcanizing, the set position becomes unstable. To cope with this, an additional bar 8 is disposed on the upper neighboring part of a rim check line 5 annularly in the peripheral direction along said line 5. Thus, the flowing of the white rubber 1 to the lower is stopped so that the set position of a white rubber 1 is made stable.

IPC: H04L1/00
Filed: 1992-09-16
Abstract: PURPOSE:To provide a cyclic encoding (CRC) circuit serving for transmission and reception without dividing it for the transmission and the reception in a TDMA (time division multiple access)-TDD (time division multiplex) communication system. CONSTITUTION:In a control circuit 21 for the transmission, data for detecting errors are prepared from the data, the prepared data are added to the original data and then the data are sent through a radio channel. That is, at the time of the transmission, a CRC encoding circuit 23 is used only for preparing the data for detecting the errors. In the control circuit 22 for the reception, only the presence of the errors is discriminated from the transmitted original data and the data for detecting the errors added at the time of the transmission. Thus, since signals required at the time of the transmission and the reception are different for the transmission and the reception and not much difference is present in the constitution of the CRC encoding circuit itself, by providing the control circuit 21 for the transmission and the control circuit 22 for the reception, the CRC encoding circuit 23 can be the circuit serving for the transmission and the reception.

Abstract: PURPOSE:To prevent hardware scale from being extended by drasitcaly reducing the total number of program switches by exclusively connecting between the pair of input signal lines (or the bundle of input signal lines) semantically equivalent to each other and a bus. CONSTITUTION:The number of signal lines consisting of the bus is assumed as 16 and the number of input signal lines is assumed as 8, and (a) and (b) are inputs, xi and xj are the input terminals of a basic cell 30 realizing function F (x0, x1...) and z0 and z1 are outputs of the basic cell 30. Wherein, the inputs (a) and (b) are equivalent to each other in terms of meaning when the outputs z0 and z1 are not changed even though the inputs (a) and (b) are exchanged, and input signal lines 31 and 32 transmitting these inputs (a) and (b) are a pair of exchangeable input signal lines. In the case when A0 and A1 of the input signal lines of the basic cell realizing a certain function F(...A0...A1...) are signal lines equivalent to each other in terms of meaning, the output of the basic cell is not changed at all even though these two signal lines A0 an A1 are exchanged. Therefore, the signal lines Wi and Wj can be connected by connecting only two intersections, thereby the number of connections are halved.
