Title: Channel selector
Inventor: TAKENAWA HIROYUKI
IPC: H03J5/02
Filed: 1984-01-25
Abstract: PURPOSE:To obtain a channel selector which receives a channel set before a power supply is turned off after the channel selection is carried out with a transmitter and then the next power supply is turned on and functions as the last channel memory, by providing two NAND gates between a control circuit and a channel selection circuit. CONSTITUTION:Two NAND gate circuits 3 are provided between a control integration circuit 3 and a channel selection integration circuit 4 of a channel selector. The voltage extracted out of a TV receiver main body 6 is applied to the gates 22 and 24 of the circuits 3 via a voltage supply circuit 7. At the same time, the channel-up/down signals are applied to the gates 21 and 23 of the circuit 3. When these signals are not available, the outputs of gates 22 and 24 are set at high levels. Then no channel selection is carried out for the circuit 4. While the outputs of the gates 22 and 24 are set at low levels when the power supply of the main body 6 is turned off. Then the channel selection is carried out. Then the channel set before the power supply is turned off is received as the last channel memory when the next power supply is turned on after receiving the channel selection operating signal is received from a receiving circuit 1.

Title: Low voltage detector for power supply unit
Inventor: OSHIGA TAKAYUKI
IPC: H02M7/12
Filed: 1990-01-24
Abstract: PURPOSE:To prevent the defect of operation cooperation even when a supplying voltage is lowered by detecting a low voltage by a third signal according to the OR condition of a first signal, which is generated by a first deciding voltage, and a second signal to be generated by a voltage less than a second deciding voltage. CONSTITUTION:When the commercial alternate current power supply voltage of 200V to be supplied to an input terminal 3 is lowered to 100V, for example, from such a time point, a voltage A is lowered under a prescribed time constant characteristic and made less than a voltage Vc at a time point after the lapse of prescribed time and as a result, a Zener's diode 10 is interrupted. Then, a voltage C is lowered to 0V and an output signal D of an AND circuit 14 is changed from a conventioned '0' to '1' and displays the low voltage. It is necessary for changing the signal D of the circuit 14 to '1' to change a voltage 13 to '1' and a voltage A is required to be higher than a Zener's voltage VB once. Since only a low voltage state can be detected during an operation with 200V as a normal voltage, in the normal operating state by the alternate current power source of 100V, it is not detected as the abnormality of the low voltage state and a secure detecting operation is obtained.

IPC: B23Q1/36
Filed: 1983-01-28
Abstract: PURPOSE:To obtain a tool abnormality detector having the most suitable sensitivity for a tool of from a small diameter to a large diameter, by building an elastic displacement mechanism, which generates torsion in proportion to cutting torque, in a tool holder and providing a detector fixed to the outside and a processor device. CONSTITUTION:A tool abnormality detector detecting the abnormality of a tool generated during its cutting is constituted such that an elastic displacement part 22 in a tool holder 20 mounted to a machine tool main spindle 5 is twisted to the center of rotation of the tool in proportion to cutting torque applied to the tool 24. This twisting angle appears as a change of the phase between a reference gear 21 and a displacement gear 23. Accordingly, detecting the phase of these gears by a detector 30 mounted to a headstock 4, the cutting torque can be estimated from a phase difference between detecting signals by a torque arithmetic unit 13 in a processor unit 10. By this constitution, the tool abnormality detector having the most suitable sensitivity for the tool of diameter from a small size to a large size can be obtained.

IPC: E01C19/26
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of work such as nozzle replacement or cleaning by arranging a single spraying pipe near the wheel of a compacting machine and connecting selectively a first pump of a first liquid tank and a second pump of a second liquid tank through a switching valve mechanism. SOLUTION: A single spraying pipe 1 is arranged near the wheel of a compacting machine. And the first pump P1 is provided on the first liquid tank T1 side and the second pump P2 is on the second liquid tank T2 side. These pumps P1, P2 are connected selectively to a spraying pipe 1 through a switching valve mechanism B1. Thus a single spraying pipe 1 is used commonly for both the first liquid and the second liquid rather than providing two spraying pipes for spraying the first liquid and the second liquid separately. Therefore, the number of spraying pipes arranged near the wheel can be reduced, a broader space can be obtained near the wheel, and the efficiency of work such as nozzle replacement or cleaning can be improved.
