Title: Operation state detection device for basket-type induction motor
Inventor: MORIKAWA AKIHIKO
IPC: H02K17/16
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To suppress a measurement error and to highly precisely detect an operation state by proving two magnetic sensors in the different positions of the output shaft direction of a basket-type induction motor. SOLUTION: A front side magnetic sensor A is installed on a front side detached from a center part by a prescribed distance by setting an arbitrary part in a shaft direction, a middle part, if possible, to be the center part, along the direction of the output shaft 3 of an induction motor 1, and a back side magnetic sensor B at a back side detached from the center part by a prescribed distance. When the induction motor 1 is operated, magnetic flux leaks to an outer part from an outer case 2. Thus, the front side/back side magnetic sensors A and B detect magnetic flux leaking to outside and output corresponding electric signals to a device main body 4. The device main body 4 displays the torque of the induction motor 1 by the torque display part 5 of a front panel and displays the rotary direction of the induction motor 1 by a rotary direction display part 6.  Thus, it is not necessary to install a torque sensor to the output shaft as in a former way, a measurement error owing to a temperature rise in the induction motor is eliminated and an operation state can highly precisely be detected.

Title: Designating system for confidential document
Inventor: WATANABE HIROSHI
IPC: G09F19/12
Filed: 1987-02-12
Abstract: PURPOSE:To prevent erasure of a confidential document display even if any copying machines are used by displaying a display color by using >=2 colors of characters having nearly a complementary color relation with each other at the time of displaying prohibition of reproduction, etc., on the document. CONSTITUTION:The confidential document display are shown at least at two points 1, 2 in the confidential document by using the two colors having the complementary color relation at the time of forming the confidential document. At least one confidential document display is, therefore, copied even if said displays are copied by the copying machine having a light source of any wavelengths. Even if the light sources of two kinds of wavelengths are going to be simultaneously used in an attempt to erase the two colors having the complementary color relation simultaneously, said colors are in the complementary color relation and, therefore, both of the confidential displays are eventually copied. The undue reproduction of the confidential document is thereby prevented.

Title: Constant current circuit
Inventor: ISHIDA TATSUYA
IPC: G05F1/56
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To take out a large output current with a wide input voltage setting range and further to reduce a layout area. SOLUTION: A voltage inputted from IN and an inverted input signal 23 of an operational amplifier are inputted to an operational amplifier 13. The operational amplifier 13 applies a voltage to the gate of an N channel MOS transistor N7. The N channel MOS transistor N7 lets a current flow to a resistor R17 corresponding to the voltage applied to the gate and voltages are generated at both ends. The P channel MOS transistor P1 lets a current flow to a resistor R18 corresponding to a voltage applied to the gate and voltages are generated at both ends. Since the gate of the P channel MOS transistor P1 to supply a constant current to be a reference can be controlled independently of the drain, there is no limit for the drain current of the P channel MOS transistor P1 so that the voltages at both the ends of the resistor R18 are not limited.
