Title: Constant current circuit
Inventor: SUGIYAMA HIDEO
IPC: G05F1/56
Filed: 1981-03-04
Abstract: PURPOSE:To obtain a stable load current against temperature change, by compensating a reference voltage against the fluctuation of a load resistance value due to temperature change. CONSTITUTION:Resistors 11 and 12 are connected between a power supply voltage Vcc and ground GND. A voltage V1 is generated at the base connection point of a transistor (TR) 13 by setting the resistors 11 and 12. According to this voltage V1, a reference voltage V2 is generated at a + side input of an operational amplifier 15. An output voltage of the operational amplifier 15 goes to high level when a voltage VL applied to a - side input is smaller than V2 (V2>VL). Thus, a load current flowing to a load resistor RL via a TR is increased. Then the state of V2>VL is obtained and the load current is controlled to be decreased. Thus, the load current is made stable independently of temperature changes.

Abstract: PROBLEM TO BE SOLVED: To enhance the strength by holding a male-member-side rotating member into place after a rod-shaped body and a seat part, supported by the male-member-side rotating member, are engaged respectively with a receiving member and another seat part which are located on the side of a female member. SOLUTION: A rod-shaped body 11 projecting from the front of the connection of a malemember-side horizontal member 2 is engaged in the grooved part of a receiving member 3 provided at the connection of a female-member-side horizontal member 1. Next, the horizontal member 2 is rotated downward about the rod 11 and is rotated about the fulcrum 9 of rotation of a rotating member 8 to engage a seat male part 5 with a seat female part 6. In this case, a rotation fixing hole 10 in the rotating member 8 is moved up to a fixing hole provided in a recess 7 in the side face of the horizontal member 2, so a bolt 13 is passed through the hole 10 and held in place by a nut to fix the horizontal members 1, 2 together.  Since the horizontal member 2 is pulled by the weight of the horizontal member 1, the rod 11 and the receiving member 3 are engaged with each other without loosening, and loosening due to thinning of wood does not occur at connections. Thus, loss of cross sections can be reduced, transportation is facilitated because of the absence of connecting projections, and fabrication is also facilitated.

IPC: H03K17/16
Filed: 1987-02-16
Abstract: PURPOSE:To reduce the off-time by supplying a constant current to a capacitive load and canceling a steep and a large rush current at polarity switching caused by the capacitive load when the constant current is subjected to positive/negative polarity switching. CONSTITUTION:A rush current suppressing circuit 10 comprising a current change detection circuit 1 and a suppression current generating circuit 2 is provided to a feeder circuit 3 supplying a constant current to a line 5 connected with a capacitive load 6 and a system having a polarity switching circuit 4 applying polarity switching to a current from the feeding circuit. In applying polarity switching by the circuit 4, a rush current is generated by an electric charge stored in the capacitive load 6. The change in the rush current is detected by a current detection circuit 1. The detected current change is inputted to the suppression current generating circuit 2, from which a suppressing current having the opposite polarity to the rush current and the same amplitude is generated and overlapped onto the load. Thus, the rush current is canceled substantially. Thus, the off-time at switching is reduced.

Title: Demodulation circuit for data communication
Inventor: ICHIKAWA YUICHI
IPC: H04B1/707
Filed: 1995-01-27
Abstract: PURPOSE: To improve the reliability of a communication system by setting optimizingly a reference voltage for data demodulation in response to a level of a received input signal so as to allow the circuit to be in response to fluctuation of ambient environment. CONSTITUTION: A signal B obtained by applying envelope detection to an input received signal A at an envelope detector 2 is given to a peak hold means 5, in which the peak level is held and provides the output of a reference voltage Vref. A comparator 3 compares a detection signal B and the reference voltage Vref and gives a signal D obtained by applying arithmetic processing to a data signal C by a control circuit 6 to the peak hold means 5. Thus, the peak hold means 5 acquires a peak voltage being a detection output at that point of time and a detection signal is demodulated into a digital data signal C based on the reference voltage and optimum data demodulation is conducted by coping flexibly with a change/fluctuation in the transmission line and the ambient environment.
