Title: Load detector for elevator
Inventor: WATANABE HIDENORI
IPC: G01G3/00
Filed: 1987-12-09
Abstract: PURPOSE:To enable refined torque control with accurate detection of a load within a cage, by arranging a load detector of an elevator made up of a detector using a high temperature superconductive material to detect a load working on a support device for supporting the cage. CONSTITUTION:When a first superconductive coil 26a is placed at a position of detection to make a detection magnetic flux phi1 of a magnetostrictive material 23 interlink it, as a connection section 26c, a second superconductive coil 26b and a Hall element 27 are magnetically shielded separately, an opposite magnetic flux phi2 interlinking the first superconductive coil 26b comes to interlink the second superconductive coil 26b. This holds a formula of L1.phi1=L2.phi2. When a flux density within the second superconductive coil 26b is represented by B2, the B2 is expressed by the following formula: B2=L1.B1/L2. As L1>L2, the flux density B2 in the second superconductive coil 26b is larger than the B1. That is, the magnetic flux is amplified to be applied to the Hall element 27 thereby enabling a highly sensitive measurement.

Title: Etching device for transparent film
Inventor: UCHIKOGA SHIYUUICHI
IPC: H01L21/306
Filed: 1989-11-30
Abstract: PURPOSE:To judge the end point of etching for a transparent film accurately by detecting the conditions of the transparent film being the film to be etched as optical change. CONSTITUTION:A light irradiation system consisting of a light source 14 and a reflecting plate 15 is provided at the upper right of a vessel 11. The reflected light 17 from the surface of a substrate 13 is guided out of the vessel 11 through a transparent plate 12, and is condensed by a condensing lens 18 and the image is picked up in a camera 19. If the reflectance, etc., are different between the transparent film formed on the surface of the substrate 13 and the base, the reflected light intensity and the image condition detected by the camera 19 vary considerably around the etching end of the transparent film. For this reason, by monitoring the surface of the substrate 13 with the camera 19, the end point of the etching of the transparent film can accurately be judged.

Title: Signal comparing device
Inventor: IGUCHI NAOYA
IPC: G01R19/165
Filed: 1988-12-09
Abstract: PURPOSE:To make the variation width of control constant by inputting the output of a comparing circuit and other >=1 signal to an internal control circuit, setting a reference signal level with the output and supplying a reference signal to one input of the comparing circuit. CONSTITUTION:When an output signal 17 is H level, transistors (TR) 12 and 36 are off and the set level of the reference signal 16 is Vref1 without reference to whether low temperature or high temperature is set. When the output signal 17 is L level, on the other hand, only the TR 12 turns on and the reference signal 16 is Vref2 in a high-temperature setting state. Similarly, when the output signal 17 is at the L level and high temperature is set, only the TR 36 turns on and the reference signal 17 is Vref3. Consequently, the difference in tempera ture rise between areas 23 and 28 which increases even when temperature is lowered can be canceled by setting the set level of the reference signal 16 low to make the variation width of the temperature control constant.

Abstract: PURPOSE: To provide a discharge lamp lighting device which increases the current capacity and does not generate the increase of the stress of the elements and the increase of a radiant noise owing to the unevenness of the characteristics of the elements. CONSTITUTION: By rectifying the all waves of an AC power source AC by a rectifier circuit DB and smoothing by a smoothing capacitor C1 , a DC power source is obtained. The DC power source is made into the power source of plural chopper circuits 1a and 1b and the chopper circuits 1a and 1b turn on and off switching elements Q1a and Q1b by a high-frequency wave depending on the signal from a control circuit 3, so as to step down the input voltage and output it. To a filter circuit 2 which consists of a capacitor C2 and a choke coil L2 , the composed current of the currents flowing through inductors L1a and L1b flows in. Since the chopper circuits 1a and 1b operate independently, the mutual influence is little and even though an evenness is generated in the characteristics of the elements, no influence is given to other chopper circuits 1a and 1b.
