Title: Detector
Inventor: IINO HIROSHI
IPC: G01S15/87
Filed: 1985-02-07
Abstract: PURPOSE:To enable the control of transmitter/receiver in any of a plurality of observing devices, by outputting a control signal for controlling the movement of the transmitter/receiver to a moving unit in response to a command signal while the level of the control signal is monitored to connect both units with a signal line. CONSTITUTION:When a control signal for lifting is outputted from a controller section 8a, a transmitter/receiver is lifted on the side of the controller section 8a free from effect of a lowering control signal even though outputted from the controller section 8b. To the contrary, when the lowering control signal is outputted from the controller section 8a, given the lifting control signal outputted from the controller section 8b, a CPU12a of the controller section 8a release the lowering control signal output by itself to lift the transmitter/ receiver by a control signal from the controller section 8b. A power source can be closed to an observing device 2a to provide a control signal to a moving unit 4 from the controller section 8a even when the power source of the observing device 2b is switched OFF. Thus, the movement of the transmitter/receiver can be controlled irrelevant to the observing unit 2b.

Title: Controller for induction machine
Inventor: MATSUMOTO NORITOSHI
IPC: H02P23/16
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To protect a brake resistor surely by estimating a temperature rise of the brake resistor from a regenerative power determined based on a value corresponding to the torque of an induction motor and a detected rotational speed thereof. SOLUTION: Based on a speed detection value N and a torque current command value iT* of an induction motor, a mode decision circuit 21 makes a decision that the motor is operating in a regenerative mode if N<0, iT*>0 or N>0 and iT*<0. Consequently, a switch 26 is turned to the regenerative power operating circuit 22 side and a regenerative power P is inputted to a heat model 23. A comparison circuit 24 compares the output from the heat model 23 with an alarm detection set value operated by an operating circuit 25. When the output from the heat model 23, i.e., a temperature rise, exceeds the alarm detection set value, an alarm signal is turned on to alarm that a brake resistor is overheated and a stop command is delivered to the controller for the induction motor. Consequently, the brake resistor can be protected accurately.

Abstract: PURPOSE:To improve the performance of ghost elimination by providing a means for using an output of a storage circuit to switch a converting reference voltage given to an A/D converting circuit and a reference voltage generating circuit generating two kinds of reference voltages to obtain a correct ghost. CONSTITUTION:An output (d) of an A/D converting circuit 9 is an overflow output and when an input signal to the circuit 9 exceeds the conversion reference voltage, the output is obtained for the exceeding period. An output (j) of the storage circuit 16 connects to a switching circuit 17, and when the output (j) is at a low level, the reference voltage of the smaller absolute value in two kinds of the reference voltages generated by the reference voltage generating circuit 18 becomes an output (k) and is used as the reference voltage of the circuit 9.

Title: Thermal recording apparatus
Inventor: KUWABARA TAKAO
IPC: B41J2/325
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce a carnation in the resistance value of heat elements caused by the use thereof, and form high quality images for a long period of time by giving a predetermined heating history to whole heal elements of an unused terminal head, and permitting the resistance value of the whole head elements to be varied beforehand by only a giving rate. SOLUTION: Althrough the heat element of a thermal head 66 varies in its resistance value in accordance with the heat hysteresis, since the heating history in each heat element differs from each other, a variation of the resistance value is different every heat element, and difference tales place in a variation of the resistance value along with the lapse of time, so that density unevenness occurs in accordance with the difference. To cope with this, a predetermined heating history is given to whole heat elements of the unused thermal head glaze 66a, and a thermal head 66 which a resistance value lowered at a given constant value is employed. When a constant heat energy is supplied, a variation of the resistance value of the heat elements is nearly in proportion to the logarithm.  By allowing the resistance value to be varied preliminarily uniformly by a given rate, difference in the variation of the resistance value subsequent to this is rendered small.
