Title: Locking nut
Inventor: MARUI KOREHITO
IPC: F16B39/34
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost nut having a locking function and preventing the damage of a lens. SOLUTION: A locking nut comprises a given female screw 2 formed; and a screwless hole 4 consisting of a screw-in part 4a having diameter equal to or lower than the effective diameter of a female screw 2 and a vertical groove part 4b more escaping to the outside than the screw-in part 4a formed on the central line of the female screw and is formed of a resin member 3. Thereby, since, during fastening, the locking nut is formed of a resin member, an elastic force is provided and an axial fastening strength is sufficiently ensured. Besides, since the screwless hole of the resin member has diameter lower than the outside diameter of a screw, during fastening, a thread is formed by the screw itself, and the outer surface of the screw is fastened by the elastic force of the resin member to prevent unfastening of the screw.  Further, since a need for a T-type washer is eliminated by an integrally molded bushing part 5, assembly workability is improved, an assembly cost is reduced, and the damage of a lens is also prevented from occurring.

Title: Electromagnetic wave detector
Inventor: COSTARD ERIC
IPC: H01L25/04
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To remove the upstream dark current and background photo current of a read circuit by providing at least two covered plane active photoconductive detector element separated by a common layer. SOLUTION: The detector comprises a contact layer C2, active photoconductive layer D2, common layer contact layer Cc, active photoconductive layer D1 and contact layer C1 are laid on a substrate. When the detector is irradiated with e.g. a radiation RZ, the active layer D2 is first irradiated with the radiation. If the response of the layer D2 is so high, the layer D2 almost absorbs the radiation at wavelengths under question and the layer Cc acts to block a wavelength λ. This enables application of a control voltage to the contact layers C1, C2. The active layer Cc is common to two detector elements composed of the active photoconductive layers. The layer C is held at a reference voltage and enables the detectors D1, D2 to detect created photo currents.

Abstract: PROBLEM TO BE SOLVED: To evaluate development of corrosion in silver or silver alloy over a long time, in a short time by performing an acceleration test by way of exposing a silver piece under the atomosphere of mixed gas formed by mixing hydrogen sulfide with nitrogen dioxide in a clean air. SOLUTION: A mixed gas composed of hydrogen sulfide and nitrogen dioxide is generated, and the gas is mixed in clean air to generate an atomosphere. In the atomosphere a silver test piece and silver contact part is exposed, and then the thickness of film of silver sulfide layer is measured. It is known that a silver alloy is corroded at about 0.42 μm/year under a natural emvironment and silver sulfide is formed thereon. It is desirable that the mixed gas has hydrogen sulfide whose concentration is 0.7-2.0 ppm and nitrogen dioxide whose concentration is 1.5-4.0 ppm while the concentration ratio therebetween is 1:1-1:3. When the mixed gas is in the range, it is possible to form silver sulfide corresponding that formed after the lapse of 5-10 years under a natural environment by exposing a silver piece and the like under the mixed gas. Accordingly, the purpose is attained.

Title: Imaging apparatus
Inventor: KATO TAKESHI
IPC: H04N5/91
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent the power switch of a printer from being missed to be turned off by detecting the voltage level of an input signal from an image data output unit and turning a power supply on the printer side on/off while interlocking with on/off or connect/disconnect operation of a power supply for the image data output unit. SOLUTION: Since an acknowledge signal can not be received in 3P communication through a 3P communication cable when the power supply of a digital camera 1 is turned off or the digital camera 1 is disconnected from a printer 20, a CPU 25 conducts a work for determining the level of an RXD signal. More specifically, the CPU 25 pulls a signal SW1 ON to L level in order to cut power supply DVCC from the printer body and pull a signal SW2 ON to H level. Since a signal PORT IN has L level when the power of the camera 1 is turned off or the 3P communication cable is disconnected, the CPU 25 determines that the camera 1 is turned before conducting system off processing.
