IPC: H04L7/00
Filed: 1990-05-22
Abstract: PURPOSE:To detect a slip with a transmitter itself by constituting the transmitter so that a test pattern checking means generates periodically a data error, when an inputted test pattern is shifted from a test pattern generated by itself. CONSTITUTION:For instance, a slip is generated in the clock of a transmission line 3-1, and when it is selected by a selector 10, a PLO 11 generates a clock synchronized therewith. A test pattern generating means 12 generates a test pattern synchronized with the clock of the PLO 11, and it is written in a buffer memory 13. On the other hand, a PLO 21 generates a clock synchronized with a clock from a transmission line 1-1 selected by a selector 20, it is sent to a test pattern checking means 14, and also, becomes a read-out clock from a memory 13, and it is read out and inputted to the checking means 14. The means 14 generates the same one as the test pattern generated from the means 12, and when the inputted test pattern is shifted from that which is generated by itself, a data error is generated periodically, and the slip can be detected.

Filed: 1986-06-06
Abstract: PURPOSE:To efficiently use a cutting recording paper by executing the reducing, dividing and selecting of a usual recording mode based on the comparing result of the number of the line of a received original and the recording length of the cutting recording paper. CONSTITUTION:Original information sent through a communicating line (a) is received by a communicating control part 1, decoded by a decoder 2 and accumulated in an accumulating circuit 3. At this time, the decoder 2 decides by what line a receiving original is constituted. A comparator circuit 4 compares the number of the detected line and the recording length of a cutting recording paper. After the result of the comparing, when the number of the line of the original exceeds the recording length of the cutting recording paper in an error scope, the picture signal is thinned by a thinning circuit 5, supplied to a recording control part 6 and reduced and recorded to a sheet of the cutting paper. When the error scope is exceeded, namely, the picture signal to exceed one page is received, the recording control part 6 divides a receiving picture signal into plural sheets of the cutting recording paper and records them.

Title: Power transmission
Inventor: MAEDA HIROAKI
IPC: F16D47/06
Filed: 1995-05-31
Abstract: PURPOSE: To provide a power transmission applicable even for a high torque vehicle by converting rotation torque of an intermediate shaft obtained through a viscous fluid coupling to thrust in the axial direction, and using the thrust force as the pressing force of a multiple disc clutch separately provided. CONSTITUTION: When an input shaft 11 is rotated, an intermediate shaft 12 is rotated through the shearing force of viscous fluid in the interior. The rotation of the intermediate shaft 12 is converted to movement in the axial direction by a cam means 17, hereby a presser member 16 is moved in the direction of engaging a multiple disc clutch 15, and hence the rotation torque of the input shaft 11 is transmitted to an output shaft 13. For enlarging transmission torque, a viscous fluid coupling must be enlarged, but the multiple disc clutch 15 is engaged by thrust force corresponding to cam angle θ generated by the cam means 17 so as to transmit rotation torque, and hence high torque can be transmitted by the viscous fluid coupling of low capacity. Further, an electric control device such as an electromagnetic switch is unnecessary.

A valve 8 is thereafter opened to introduce a Krr 85 gas from a cylinder, etc., connected to a pipe 9 into the vessel 1 and a specified pressure, for example, 0.1Torr is maintained in this vessel 1. The valve 8 is closed to put the vessel into the hermetic state after the specified pressure is attained. A refrigerant is passed to a cooling pipe to cool an electrode 5 and the vessel 1. Desired electric power is supplied from a power supply to a filament 21 of the electron gun 23 to generate thermions. A high voltage of several kV is impressed to an electrode 22 and electron rays 25 are guided into an ionizing chamber 2. A negative DC high voltage is impressed to the electrode 5 by a 1st DC high voltage power supply 17 and a negative DC high voltage is continuously impressed thereto from a 2nd DC high voltage power supply. The above-mentioned electron rays 25 are thereby contributed to an increase in glow discharge, by which the ionization efficiency and ion implantation efficiency are enhanced.
