Inventor: BOKUDAN BURAKUSU
IPC: H02M3/335
Filed: 1989-03-02
Abstract: PURPOSE: To eliminate the waste of demagnetizing energy by choosing a capacitance such that a resonance circuit formed of the capacitance of the capacitor of a demagnetizing device and the shunt inductance of a transformer has a resonance frequency approximately equal to a main resonance circuit. CONSTITUTION: A demagnetizing device for demagnetizing the core of a transformer after the turn-on phase of an electronic switch S includes an additional capacitor C3, connected to the secondary winding W2 of the transformer. The capacitance of the additional capacitor C3 is chosen, so that an additional resonance circuit of the capacitor C3 and the shunt inductance Lq of the transformer has a resonance frequency which is equal to the main resonance frequency of a resonance circuit, including an inductance L1 and a capacitance C1. In fact, no inductive voltage peak is generated in the electronic switch S, at the time of its being cut off by using a demagnetizing network.

Filed: 1983-03-25
Abstract: PURPOSE:To attain the composite photographing with no disturbance of reproduced pictures produced at a joint by giving comparison to the sum of frequency differential component of four sets of pilot signals which are multiplexed cyclically to a track and having a prescribed relation in frequency difference. CONSTITUTION:The pilot signals having relations f1-f2=f3-f4= fh and f2- f3=f4-f1=3fh obtained among frequencies f1-f4 are recorded cyclically on a tape every adjacent track and in a multiplex way. Therefore the equal sum is obtained between reformed frequency differential components fh and 3fh regardless of a shift of the head position to a track as long as the recording is performed to the adjacent track. While said sum varies with a joint having no recording on the subsequent adjacent track. The joint is detected accurately by a fact whether or not the sum value is specific. This it is possible to perform the composite photographing with no disturbance of produced pictures at a joint.

IPC: B60T8/50
Filed: 1993-03-10
Abstract: PURPOSE:To obtain roughly constant boosting speed without depending on pressure when boosting is started by repeating braking again and decompressing while being adjusted to the various surface condition of roads on and after the specified period of time has been over when decompression condition has continued over a specified period of time. CONSTITUTION:While a skid signal is being received by a control module 7, a solenoid operation type discharge valve 5 keeps opening, and a master cylinder 1 keeps supplying hydraulic oil to a brake 2a. When the skid signal is over, the discharge valve 5 is closed. In this case, when decompression has continued over the specified period of time, a braking-again condition Tu and a decompression condition Td are so devised as to be repeated on and after the specified period of time has been over. Namely, when it is detected by a timer that the specified period T of time has elapsed, a boosting time constant is set in the timer, so that boosting control is then performed with the discharge valve 5 demagnetized. Next, decompression time Td which is cyclically changed, is set in the timer, a decompression condition is set again by the discharge valve 5, and the aforesaid operations are then repeated.

Title: Method of casting polymer sheet and device thereof
Inventor: YOSHIZAWA NAOHIKO
IPC: B29C48/08
Filed: 1986-03-06
Abstract: PURPOSE:To ensure the stability of production by a method wherein casting is performed under the state that the tension of a wire-shaped electrode is controlled to be constant. CONSTITUTION:In order to control the tension of a wire, at first, a target tension is determined and a torque is roughly calculated so as to set the input voltage of a torque motor 4. The torque of a brake motor is set a little larger than that of the torque motor 4. The tension, which is roughly set as mentioned above and indicated with a tension detecting mechanism 7, is made equal to the target tension by finely controlling the input voltage of the torque motor. In this case, care must be taken to keep the torque of the brake motor larger than that of the torque motor at all times. Under the above-mentioned setting condition, even when the tension gets loose due to the linear expansion of the wire, the torque motor automatically rotate so as to keep the tension constant. Further, when the change of the tension is intended, the change of the set value of the torque motor is enough.
