IPC: B60L11/18
Filed: 1995-06-28
Abstract: PURPOSE: To prevent the collision between a power transmitting-side coupler and a power receiving-side coupler used for a battery charger when the couplers are put upon another. CONSTITUTION: A power transmitting-side coupler 4 is composed of a power transmitting-side electromagnetic coil 6 and a power transmitting-side core 5. A power receiving-side coupler 7 installed to the bottom face of a vehicle is composed of a power receiving-side coil 9 and a power receiving-side core 8. When the couplers 7 and 4 are put upon another, the coil 6 enters the internal space of the coil 9. When the coil 6 enters the internal space, large intervals are obtained between both coils 6 and 9 in the forward-backward direction. When a charging current is made to flow to the coil 6, an electromotive force is induced in the coil 9.

Title: Method for determining polysaccharide derivative in low-molecular organic compound
Inventor: MUROMOTO CHIE
IPC: G01N30/88
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To simply, quickly and highly accurately identify and determine a polysaccharide derivative which is included very small in a low molecular organic compound, by using both an ultraviolet absorption detector and a multi wavelength detector as a detecting means in gel permeation chromatography(GPC). SOLUTION: A mobile phase is preliminarily fed by a liquid feed pump 2 from a mobile phase container 1 to obtain a stationary state. Then, a sample is injected by a manual injector 3. The injected sample is sent to a GPC column 4 in a column oven 5 and detected by an ultraviolet absorption detector 6 and a multi-wavelength detector 7. The ultraviolet absorption detector 6 is installed to determine a polysaccharide derivative, which calculates a content of the polysaccharide derivative from a peak area of the detected polysaccharide derivative. The multi wavelength detector 7 is to identify the polysaccharide derivative, which compares a waveform of a standard polysaccharide derivative with a waveform of the polysaccharide derivative in the sample thereby identifying the polysaccharide derivative. The obtained data are identified and determined by a data-processing device 8.

Abstract: PURPOSE:To form a microlens on a CCD type imaging device by a simple process. CONSTITUTION:A positive type lens material resist layer 20 is formed by coating on the surface flattening layer 19 of a CCD type imaging device 11. Subsequently, a part, corresponding to the lens forming area, is exposed employing a photomask 21 having mask patterns 21a at parts corresponding to lens forming areas.

Title: Power receiving facility
Inventor: TANAKA YASUHIRO
IPC: G05F1/70
Filed: 1995-06-05
Abstract: PURPOSE: To obtain a power receiving facility in which the power factor can be improved appropriately through automatic control even under a light load by closing the switching means for each main capacitor selectively at the main control section of a power factor regulator depending on the reactive power under a normal load where the effective power of a load side bus exceeds a first reference level. CONSTITUTION: Effective and reactive powers of a load side bus 6 are determined at the power operating section of a power factor regulator 16. When the effective power thus determined exceeds a first set reference level for detecting a light load, the switch 13 for each main capacitor 10 is closed selectively at a main control section 18 depending on the reactive power. The switch 13 for sub-capacitor 11 is closed at a sub-control section 19 during an interval when the effective power is higher than a second set reference level for detecting a light load but lower than the first set reference level. The switch 13 for sub-capacitor 11 is opened at the sub-control section 19 when the effective power drops below the second set reference level. This constitution can improve the power factor appropriately through automatic control even under a light load.
