Title: Power supply interruption system
Inventor: YAJIMA HIDEHARU
IPC: H02H5/00
Filed: 1991-09-18
Abstract: PURPOSE:To prevent inadvetent turn ON of power after removal of housing cover by optically detecting the fixing state of the housing cover and interrupting power supply according to the detection results. CONSTITUTION:When a cover 7 is fixed to a housing body, optical energy emitted from the light emitting section 311 of a photoreflector 31 is reflected on the housing cover 7 to be fed to the light emitting section 312 of the photoreflector 31. Upon removal of the housing cover 7 from the housing body 8, optical energy is not fed from the light emitting section 311 to the light receiving section 312 of the photoreflector 31 and the light receiving section 312 is brought into nonconducting state. Consequently, the terminals T46, T47 of the switching control circuit 41 in a DC stabilized power supply circuit 4 are brought into nonconducting state and no power is outputted therefrom.

Title: Biosensor and its manufacture
Inventor: NAKAGAWA TORU
IPC: G01N27/327
Filed: 1994-10-31
Abstract: PURPOSE: To provide a biosensor in which a protein is firmly fixed to a base plate, and the protein is hardly denaturated by fixing the protein which is a sensor molecule and an organic thin film onto the base plate, and fixing the sensor molecule to a hole in the organic thin film. CONSTITUTION: Since a protein 1 is present in the hole of an organic thin film 4, it is firmly fixed. No chemical modification of the protein 1 is required, and therefore, the protein 1 is never denaturated. Further, since the film is Si-O bonded to a base plate 3, the peeling of the film from the base plate 3 and the peeling of the protein 1 according to it are never caused. Since the protein 1 has a plus or minus ion in solution, an electrode is used as the base plate 3, the organic thin film 4 having a pinhole is fixed to the electrode surface, and a fixed voltage is applied while dipping it in the protein solution. Thus, the protein molecule is attracted by the electrode, and fixed in the pinhole within the film.

Abstract: PROBLEM TO BE SOLVED: To provide a power supply device, a discharge lamp lighting device, an illumination appliance and a bulb-type fluorescent lamp, for which a high-side driver is not constructed and a simplified control circuit is used, and which avoids a phase advancing switching. SOLUTION: A discharge lamp lighting device 10 is composed of an inverter circuit 12 which has a high-side switching device FET2 and a low-side switching device FET1 of which a half-bridge consists, a power supply 11 which supplies a DC power to the circuit 12 and a load circuit 13 including a fluorescent lamp FL, an inductor L1 and a pre-heating capacitor C3 which are connected to the output of the circuit 12. The switching of the switching device FET2 is controlled by the resonance current of the load circuit, and the device FET1 is controlled by a driver 15. The device FET1 is turned off when a current flows from the source to the drain or when an overcurrent flows from the drain to the source.  Therefore, when the lamp FL is started even if the resonance frequency of the non-lighting time equivalent circuit of the load circuit 13 is increased, the phase advancing switching of the device FET1 can be avoided.
