Title: Non-linear compensation circuit for television transmitter
Inventor: YAMAGATA YOSHINORI
IPC: H04N5/067
Filed: 1993-01-14
Abstract: PURPOSE:To provide a non-linear compensation circuit for television transmitter which enables power amplification with few circuit scale and high efficiency. CONSTITUTION:In a non-linear compensation circuit, the high frequency signal supplied to an input terminal 1 is divided into two in a distributor 3. The one of the high frequency signals distributed by the distributor 3 is amplified in an amplifier 5. The high frequency signal from the amplifier 5 is inputted in a limitter circuit 7. In the limitter circuit 7, amplitude is made to be limited by inputting the high frequency signal in a diode bridge composed by performing a ring connection for a limitter diode via an input side high frequency transformer and by inputting the value set by a variable bias circuit 9 in the diode bridge. The high frequency signal after the limitation of amplitude is inputted in an output side high frequency transformer and the signal is inputted a variable attenuator 11 after unnecessary components are eliminated at this place. The high frequency signal from the variable attenuator 11 and the high frequency signal from the distributor 3 are synthesized by a synthesizer 15 and it is outputted from an output terminal 13.

Title: Signal transfer circuit for asynchronizing signal
Inventor: GOKO HIRONORI
IPC: H04J3/06
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a signal transfer circuit for an asynchronizing signal that is small in the circuit scale and suitable for large scale circuit integration. SOLUTION: In the case of transferring a signal only at a specific time denoted by a transfer instruction signal 2 among transferred signals, when the transfer instruction signal indicates transfer, a counter 3 is operated to sequentially store the transfer signal 1 and the transfer time, that is, an output of a counter 4 to storage circuits 5-1, 5-2. The stored transfer time is always compared with a count of a counter 7 and the signal is transferred at a coincident time. Thus, the signal can be transferred by preparing storage circuits 5 and comparator circuits 11 of a minimum scale.

IPC: H01B3/44
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent spots from being generated by controlling at a specific proportion or under the amount of unreacted silane in a silane graft polyethylene in a cross-linkable resin composition containing a silanol condensed catalyst, a carbon black and the silane graft polyethylene, the cross-linkable resin composition which is cross-linked in the presence of water or water vapor after extruded and coated on a conductor. SOLUTION: A silane graft polyethylene is obtained, whereby a silane compound containing a hydrolytic organic group and an unsaturated organic group such as a vinyltrimethoxysilan are graft-polymerized with various polyethylenes, in the presence of an organic peroxide and denature to be water cross-linkable. The amount of unreacted silane is controlled at 0.3% or less. Thereby, white spots produced whereby an unreacted vinyltrimethoxysilan is not away by water vapor and hydrolysates thereof are condensedly cross-linked is prevented from being generated in an inner layer part, when wound around a drum so that reducing a cross-lining temperature or canceling winding in a multistage is made unnecessary. Aditionally, an organometallic compound, etc., containing an organotin compound is used for a silanol condensed catalyst.

Title: Work station address setting method
Inventor: MURASE MIKITAKA
IPC: H04L12/40
Filed: 1989-01-12
Abstract: PURPOSE:To automatically add a work station address by communicating information between the work station and a host with succeeding work stations disconnected to determine the address at the time when the work station to which the work station address is not added is turned on. CONSTITUTION:Three work stations (WS-A, WS-B, and WS-C) are connected, and the power source of the WS-B is turned off and the address is not set. When the power source of the WS-B is turned on, the WS-B turns off its own switch 2b in a pause of data transfer of the WS-A and the WS-C. When detecting polling to the WS-C from a host 1, the WS-B informs the host that the power source of the WS-B itself is turned on. The host 1 is informed of turning-on of the power source to report the WS-B to a new work station address. The WS-B turns on its own switch 2b to transfer data between the WS-B and the host 1.

Title: Control method for load distribution in compressors running in parallel
Inventor: TAKEDA KAZUHIRO
IPC: F04D27/00
Filed: 1990-01-17
Abstract: PURPOSE:To equalize consumed power of respective drive machines by correcting pressurized gas flow setting value for one side compressor so that the ratio of fuel flow detected values of respective drive machines is a prescribed value, instituting the signal after correction as one side setting value of the control system, and instituting the value subtracting this from the setting value of two systems as the setting value of the other control system. CONSTITUTION:A compressor 1 is instituted to be overloaded, compared with a compressor 21. The ratio fuel flow of a drive machine 22 to that of a drive machine 2 is larger than the number 1.0. When the ratio 1.0 as an output signal of a load distribution setting device 44 is output, a correcting signal is output from a load distribution controller 45 so as to be the flow ratio of 1.0. When it is multiplied with a correcting signal of half of necessary flow as the setting value of a flow controller 30 and enlarged so as to increase consumed power of the drive machine 22, rotating speed of the drive machine 22 and the consumed power are increased. Nextly, the setting value of the flow controller 30 is subtracted from the necessary flow as the output of a flow setting device 46, to obtain the setting value of a flow controller 10. Hereby, rotating speed of the drive machine 2 is lowered, and consumed power of the drive machines 2, 22 coincide with each other.
