Title: Signal detecting circuit
Inventor: KAMEYAMA TADAHIKO
IPC: G11B5/09
Filed: 1982-01-19
Abstract: PURPOSE:To ensure a stable and accurate detection of signals, by giving the time differentiation to a reproduced signal supplied from a digital magnetic recorder and discriminating signals from the amplitude between the positive and negative peaks of said time differentiation. CONSTITUTION:A reproduced signal is differentiated by a differentiating circuit 10. The positive and negative peak voltages of the differentiated signal S10 are held at peak holding circuits 11 and 11' respectively. Then the held peak values are compared at comparators 13 and 13', and the outputs of comparison are supplied to AND gates 17 and 17' respectively. On the other hand, detecting signals are applied to gates 17 and 17' to detect the positive and negative peaks of the reproduced signals supplied from zero level cross detecting circuits 15 and 15'. Thus detecting signals are delivered from the gates 17 and 17' to detect effective positive and negative peak points of the reproduced signal. This detecting signal is applied to an FF18 to obtain a detecting signal S18. In such a way, the signals can be detected in a stable and accurate way.

Title: Constant current power supply circuit
Inventor: SUZUKI KAZUYA
IPC: G05F1/56
Filed: 1986-01-16
Abstract: PURPOSE:To fix a load current by raising a reference voltage value of a comparing amplifier to increase the current flowing an output current detecting element when the impedance of a load is increased to reduce the current flowing to a photocoupler. CONSTITUTION:When an impedance R4 of a load 4 is increased, a comparing amplifier circuit 5 reduces the current supplied to a light emitting diode of a photocoupler 10 to raise the output voltage of a power supply circuit 2, thereby making the current flowing to an output current detecting element 3 constant. An output current I0 is smaller than a nominal value by the reduction of the current flowing to the photocoupler 10. When the impedance R4 of the load 4 is increased, the output voltage of the power supply circuit 2 is raised to increase the current supplied to a resistance 11 from an impedance element 12, and the current flowing the element 3 is increased because the reference voltage value of a comparing amplifier 7, and the reduction of the output current due to the reduction of the current flowing to the photocoupler 10 is compensated.

Title: Oscillator
Inventor: HIGUCHI YUJI
IPC: H03L7/00
Filed: 1987-01-16
Abstract: PURPOSE:To introduce the normal output of an oscillation circuit without causing any phase shift even if a master oscillator circuit is faulty and its output is disconnected by using a master oscillation circuit being a reference and a slave oscillation circuit oscillated synchronously with its output, coupling both oscillation outputs by means of a gate circuit and leading it out as a single output. CONSTITUTION:If the main oscillation circuit 1 is disconnected due to a fault, since an AND gate 8 is closed, a flip-flop 9 is reset, then an AND gate 10 is opened. Thus, the output 5 of a relaxation oscillation circuit 4 is supplied as one input of an OR gate 3 via the AND gate 10 in the open state. In such a case, since the output 2 of the oscillation circuit 1 supplied to the other input of the OR gate 3 is diconnected, the OR gate 3 leds the output 5 of the relaxation oscillation circuit 4 as it is. In such a case, since the output 5 of the OR gate 3 is synchronized with the output 2 of the oscillation circuit 1 just before the oscillation stops, the phase disturbance in the clock signal 12 at the changeover of the oscillated output is not caused.

Filed: 1990-01-17
Abstract: PURPOSE:To enable formation of a good superconducting layer without peeling of the superconducting layer from a substrate by forming the superconducting layer on a ceramic substrate and a magnetic layer on the superconducting layer. CONSTITUTION:The superconducting layer 12 is formed on a glass ceramic substrate 11, and a magnetic layer 13 is formed on the superconducting layer 12. Namely, since the superconducting layer 12 consists of a same kind of glass ceramic as the substrate 11, this prevents peeling of the superconducting layer 12 from the substrate and causes no chemical reaction between the superconducting layer 12 and the ceramic substrate 11 during the layer 12 is formed. Thereby, such a magnetic disk is obtained in which good superconducting layer 12 can be formed without peeling of the superconducting layer 12 from the substrate 11.

Filed: 1988-01-18
Abstract: PURPOSE:To reduce the noise and vibration at the time when the air is discharged out of a hot water pipe by disposing an air vent in the hot water pipe at a level higher than the water surface in a cistern tank, and forming a bend in the lower part of the hot water pipe. CONSTITUTION:A bend 26A is formed in the lower part of a hot water pipe 26 extended into a cistern tank 18 which is oriented toward the side wall of the cistern tank 18 at an angle theta of about 30-50 deg. relative to the vertical. A part of the upper wall of the bend 26A is cut out for a certain length to form an air vent 27, and, at least, the upper end of the air vent 27 is higher than the water level at its upper limit in the cistern tank 18. Although the water remaining in a hot water making heat exchanger 17 is turned into steam by the remaining heat, and the air in the hot water pipe 26 is pushed down due to the resultant pressure higher than the atmosphere pressure, such high-pressure air is discharged to the atmosphere in the cistern tank 18 out of the air vent 27, and so, it will not be discharged into the water body in the cistern tank 18.

Filed: 1986-01-16
Abstract: PURPOSE:To freely set a temperature coefficient in a specific range and to make the range of a usable supply voltage independent of the temperature coefficient to be set selectively by selecting a resistance ratio of the first resistance to the second resistance. CONSTITUTION:When the first resistance R1 is connected between emitters of the first and second NPN transistors TRs Q3 and Q4 and the second resistance R2 is connected between emitters of the second and third NPN TR Q4 and Q5 and the emitter of the second NPN TR Q4 is led out as an output terminal TOUT, an output current IOUT is given in accordance with a formula I. If temperature coefficients of resistances are not taken into consideration, the first term of the formula I is proportional to VBE and is about -3000 ppm/ deg.C negative temperature coefficient, and the second term is proportional to an absolute temperature T and is about +3000 ppm/ deg.C positive temperature coefficient. Consequently, the temperature coefficient is set freely in the range of -3000-+3000 ppm/ deg.C by selecting the resistance ratio of the first resistance R1 to the second resistance R2. Thus, the temperature coefficient is selected freely in the wide range and the range of the usable supply voltage is made approximately independent of the set temperature coefficient.

Abstract: PURPOSE:To prevent malfunction by noise and to easily demodulate each of SIF signals by performing identification detection of sound inter-carrier frequency (SIF) signals by FM detection in performing demodulating reproduction of each of SIF signals whose frequency is different. CONSTITUTION:SIF signals of 6.5MHz, when led out from inter-carrier detection circuit 1, are inputted through filter 11a into FM detecting IC12 and are detected. The same is applied to SIF signals of 6.0MHz. In case of SIF signals of 5.5MHz, they are not inputted into IC12 and a detection is not conducted. Switch signal generator 17 relative to each SIF signal input outputs switch signals Sa, Sb, and Sc, by which switch circuit 3 and oscillation circuit 6 are controlled based on its detection input. As a result, outputs of mixed circuit 5 are made as SIF signals of 5.5MHz and inputted through ceramic filter 7 into IC2 to be sound detected.
