Title: Speed controller for induction motor
Inventor: SETO MAKOTO
IPC: H02P27/06
Filed: 1982-04-01
Abstract: PURPOSE:To enhance the responding speed of an induction motor by providing a phase angle controller which calculates a phase angle from a current command signal to a current controller and an excitation current component. CONSTITUTION:A phase controller 13 is provided with reverse tangential controller 14 and a differentiator 15. The controller 14 inputs as an excitation current component of an induction motor 6 a speed set signal, and calculates the torque current component of the motor 6 from the excitation current component and the current command signal. After the phase angle signal is outputted from the controller 13 and added by an adder 16 to the speed set signal, it is inputted to an angular frequency controller 12.

Patent JP-H01231294-A (JP)
Title: Lighting equipment
Inventor: SHIMIZU KEIICHI
IPC: H05B37/02
Filed: 1988-03-09
Abstract: PURPOSE:To make it possible to inform a user of reduction in power consumption and restart of power supply by switching lighting ON/OFF constitutions of a light source by means of a switch provided on a remote position and a lighting fixture, and lighting an auxiliary light source when power is supplied after a long stop of power supply. CONSTITUTION:As power supply to a lighting fixture 3 is shut for a short time upon only operation of first and second normally closing switches 5, 6, the power supply is not shut for a long time to the fixture. As a result, the lighting ON/OFF conditions of the respective switches 1, 2 can be switched at every operation of the switches 5, 6. Only an auxiliary light source 2 is normally lighted when power is resupplied after the stop of power supply for a longer time than that caused by the operation of the switches 5, 6. It is thus possible to reduce the power consumption with respect to the case that the main light source 1 is lighted, and to inform the restart of power supply to a user.

Title: Stroke sensor
Inventor: TAKEUCHI YUKIHISA
IPC: F15B15/28
Filed: 1991-02-27
Abstract: PURPOSE:To obtain a stroke sensor which can be manufactured without consuming much labor and time and can highly accurately and highly sensibly make detection. CONSTITUTION:Signal sections 3 are formed at regular intervals in the axial direction around the outer periphery of a nonmagnetic rod member 1 and each signal section 3 is formed by plating an Fe layer in a groove cut into the member 1 to a fixed depth. When the signal sections 3 pass through detection coils 4A and 4B, the impedances of the coils 4A and 4B periodically change and the moving amount of the member 1 is detected from the periodical changes of the impedances. Since the signal sections 3 are formed by plating, the need of a welding process and another process for removing the thermal stress produced at the time of welding can be eliminated and, at the same time, the sections 3 can be formed with high accuracy. In addition, since the permeability variation is large, the moving amount of the member 1 can be detected with high sensitivity. Since the signal sections 3 can be formed on the surface of the rod member 1 in a solid and compact texture, the sliding characteristic of the rod member 1 is not deteriorated.

Title: Liquid crystal device
Inventor: SAITO YASUHIRO
IPC: G09F9/35
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in the starting property of a fluorescent lamp to turn on, or to prevent increase in the size or cost of the device. SOLUTION: When the power supply of the liquid crystal device 1 is turned off, a liquid crystal panel P is in a light-shielding state and a fluorescent lamp 2 is not irradiated with light and has poor starting property to turn on. When the power supply of the liquid crystal device 1 is turned on, the liquid crystal panel P is temporarily changed into a transmitting state and the external light L transmits through the liquid crystal panel P to irradiate the fluorescent lamp 2 and to improve the starting property of the lamp 2. Then in the stage with the improved starting property, the fluorescent lamp is turned on. Therefore, no exclusive device to improve the starting property is required, and thus, increase in the size or cost of the device can be prevented.
