IPC: H03D3/02
Filed: 1978-07-18
Abstract: PURPOSE: To secure an instantaneous generation of the signal which is proportional to the phase difference between the reference signal and the input signal by giving a logic treatment to the reference signal, the input signal, the complementary signal to the reference signal and the shift signal obtained by shifting the input signal each.  
     CONSTITUTION: Adder 1 supplies input signal FB to be supplied to terminal 10 and then delivers signal FB or its shift signal FBSHF. Forward/backward inverse amplifier 2 uses the output of adder 1 as the input signal and then gives it the forward or backward inversion for output. complementary signal generator 5 supplies reference signal REF to terminal 11 and delivers complementary signal featuring the sum with REF always equal to the peak value. And in case both REF and FB are at the rise and fall parts owing to the rise/fall decision output signal of FB in comparator 7 plus the rise and fall signals of RE at terminal 13 or vice versa, the arithmetic process is given based on the decision at decision circuit 8 and according to the fact that REF or FB or comparator 6 is higher or lower than the average level. Thus the signals proportional to the phase difference between REF and FB are delivered momentarily from adder 3 and with no time delay.

Title: Pulse noise elimination circuit
Inventor: TANAKA KOUICHI
IPC: H03G3/34
Filed: 1978-07-17
Abstract: PURPOSE: To minimize the deterioration of the sound quality by giving the signal compensation with a high continuous property as much as possible at the front and back of the blank part occurring at the area where the pulse noise is eliminated.  
     CONSTITUTION: In case the input signal features the sine wave and contains the pulse noise, part of the input signal is amplified and filtered to generate the control pulse. And thus gate 13 and 14 are controlled to cut off the pulse noise. Then output waveform (b) is obtained when the circuit opened at the point of resistance R 0 . The output of amplifier 12 contains the signal featuring more advanced phase than waveform (b), and gate 13 and  14 are gated at one time to secure waveform (c). At the same time, the puse noise features the high frequency and thus emerges at the same position with the noise eliminated, and the blank part features the value right before the gating action by capacity C 3 . The compensation is given so that that the voltage at point A increases gradually while the gate is open, obtaining output waveform (d) or (e). If the noise is given while the signal wave is falling, the voltage at point A is compensated to decrease gradually. Thus the blank is compensated by the signal featuring the slope in the same direction while the gate is open, obtaining the continuous signals.

Title: Ink type dot-printer
Inventor: MORITA YOSHIHISA
IPC: B41J2/305
Filed: 1979-07-11
Abstract: PURPOSE:To obtain the titled printer simple in construction and capable of furnishing excellent printing quality by a method wherein an ink is supplied to an ink impregnating member from a sub-tank by a capillary action, and printing of an optional density is available by changing the position of the sub-tank. CONSTITUTION:The liquid surface level at an ink tank 31 is located at a position forming a pressurizing condition against the liquid surface at a sub-tank 34. The ink surface level contained in the sub-tank 34 is maintained at a constant value by an ink discharge pipe 38, while the ink is sucked up by the capillary action of an ink impregnating member 29, making the surface of a wire 21 at wet condition. The speed of an ink moving through the capillary tube within the ink impregnating member 29 is defined by the formula, where; r is the radius of a capillary tube; P is a pressure; is a viscosity, and h is the length of the capillary tube. The amount of the ink flowing through the capillary tube per unit time is in inverse proportion to h when other conditions are equal. By moving the sub-tank upward by operating a lever 35, the ink absorbing amount increases making the printing density deep, while the downward movement of the sub-tank makes the printing density thin, thereby the printing density can be set at an option by the operation of the lever 35.

Filed: 1983-05-19
Abstract: PURPOSE:To continue the processing despite the generation of a fault of a register by providing a space register and at the same time performing the discrimination of the fault and the switch control by a secondary processor. CONSTITUTION:If a register R1, for example, has a fault, a detection part 5 delivers a detection signal E1 to a control part 6. The part 6 transfers the signal E1 to a secondary processor 1. The secondary processing part 7 of the processor 1 knows the fault of the register R1 by the signal E1 to set the information to a memory 4 and also start a control part 8. The part 8 reads the data out of a memory M and transfers it to a shift register 2 to update the contents of the register 2. As a result, only the information on digits S1 and S2 of the register 2 is inverted and threfore gate circuits G1 and G10 are closed and opened respectively with a gate circuit GL opened. Thus the data D1 given from a main processing part 3 is set to a spare register L, and the register R1 is switched to the register L.
