Patent JP-S62227227-A (JP)
Title: Analog signal transmission equipment
Inventor: FUJISAKA NAOTO
IPC: H04B14/00
Filed: 1986-03-28
Abstract: PURPOSE:To send a signal from DC to a high frequency without using a special complicated expensive circuit and decreasing the upper limit of the transmission frequency band by using a sampling filter so as to obtain a potential representing a zero level and other potential thereby reproducing the zero potential. CONSTITUTION:A transmission signal from a transmitter 10 is received by a reception circuit 21 in a receiver 20 and demodulated by an IF conversion demodulation circuit 22. The demodulated signal is similar to a modulation waveform outputted from a switch circuit 13 and the DC component is fluctuated by a carrier frequency, e.g., temperature change. The demodulation signal is fed to a PLL 23 and a sampling filter 24 and the PLL 23 extracts the signal of the same period of the zero level synthesized by the transmitter 10 from the demodulation signal, that is, the output signal of an oscillation circuit 12. Since the zero potential is reproduced by obtaining a difference between the potential representing the zero level and other potential by the sampling filter in this way, even when the level of the reception signal and its demodulation signal is suddenly changed, no effect is received.

Title: Thyristor switch firing device
Inventor: KONISHI SHIGEO
IPC: H02M1/08
Filed: 1983-04-26
Abstract: PURPOSE:To reduce the size of a thyristor switch firing device by obtaining a power source for the firing device from an output fed through an impedance element from the voltage at both ends of thyristor group and an output of a transformer provided in the main current path of the thyristor group, thereby eliminating a separately provided power source. CONSTITUTION:A phase advancing capacitor C is opened or closed by a thyristor switch TH connected in series in the number in response to applied AC voltages with thyristor groups connected in anti-parallel with each other to compensate the reactive power. At this time the capacitor C is charged by a current rectified through an impedance element Z from the voltage eTH at both ends of the group during the OFF period of the thyristor group, charged by the current rectified from the output of a current transformer CT provided in a main current path during the ON period, and applied to firing devices T1-Tn, thereby controlling the thyristor group. Therefore, a power source for the firing device separately provided can be eliminated, reduction in size and high efficiency can be performed without using a high withstand transformer.

Title: Method of displaying amount of regenerated solvent
Inventor: AKAZAWA SHINICHI
IPC: G01F3/36
Filed: 1989-03-24
Abstract: PURPOSE:To secure good maintenance, maintain solvent always in an optimum state an improve cleaning efficiency by digitally grasping the amt. of the regenerated solvent for use in the cleaning of printed boards, etc., at the time of regeneration. CONSTITUTION:An impurity contg. solvent 5 is gasified in a gasification chamber 2 of a regenerative device 4 and then condensed back into the liq. in a condensation chamber 3. The liq. thus regenerated is introduced into a water separating tank 6 provided with a pair of liq. level sensors 7 and 8 in order to measure the time required for the liq. to reach the upper liq. level sensor 8 from the lower liq. level sensor 7 and calculate the amt. of regenerated liq. per unit time for digital display. After the liq. level has reached the upper liq. level sensor 8, the regenerated liq. is sent into a regenerated liq. storage tank 10 by a pump 9 until the liq. level is lowered to the lower liq. level sensor 7. When the liq. level has reached the lower liq. level sensor 7, the above-mentioned procedure is repeated to effect the digital display of the regeneration ability of the regenerative device at a nearly constant interval. The adjustment in this way of the amt. of the waste liq. to be drawn out and the amt. of the regenerated liq. to be fed permits the solvent in a print substrate cleaning process to be maintained in an optimum state.

Filed: 1986-03-31
Abstract: PURPOSE:To prevent generation of a flaw on the tip of a subsequent material by controlling the approaching speed of the material and the conveying speed of the table to be approached to the synchronous for all times. CONSTITUTION:A computing element 34 calculates a time t1 when the end edge of a preceding material 42 passes through a table 2 and arrives at a sensor 5. In the same way, a computing element 35 calculates a time t2 when the tip of a subsequent material 43 passes through a table 1 and arrives at a sensor 4. Further, a computing element 36 calculates a time tac needed to increase and decrease a conveying speed V2 to V1 of the table 2. Here, a discriminator 39 compares a calculated value t1+tac of an adder 38 and an arithmetic value t2 of the computing element 35. At such a result, at the time of t1+tac<t2, the speed of the subsequent material 43 to approach into the table 2 and the conveying speed of the table 2 are synchronized, and at the time of t1+tac>t2, respective speeds come to be different speeds. At such a time, a discriminator 40 generates a speed changing command and determines a speed changing timing.
