Abstract: In white balance adjustment adopting a feedback control technique, after white balance has been established at a certain color temperature, a lead-in limiting frame may be shifted following the establishment of the white balance, causing an incorrect operation to be carried out for a next change in color temperature.

Abstract: A canceling structure of a combination switch is disclosed, which ensures the returning moment of a cancel cam without increasing the size of a spring. A cancel cam 20 placed on a swing block that can be rotated with a control lever includes pressure contact surfaces 22 on a plane passing through the shaft center of an upper shaft 9b, and the upper shaft 9b is guided along a long hole 9b of a cover. An elastic contact material 30 has pressure surfaces 32 to be brought into contact with the pressure contact surfaces of the cancel cam, and is biased toward the cancel cam along a guide 6d by a coil spring 11 inserted into a blind hole 12b. The pressure surfaces 32 have a shaft-escaping recessed portion 34 forming a predetermined gap between them and the upper shaft 9b when brought into contact with the pressure contact surfaces of the cancel cam.

Abstract: The present invention discloses a hydraulic fluid accumulator comprising a housing having an interior subdivided into three chambers, with the first chamber being filled with a gas and separated from the second chamber by a first media separation element, the second chamber being filled with a fluid and separated by a second media separation element from the third chamber that is also filled with a fluid and connected to a hydraulic port. To safeguard an effective separation of media within the hydraulic fluid accumulator and, thus, a significant increase in its functional safety, the present invention arranges for the second media separation element to be embodied by a metal piston delimiting a chamber that can be vented in the housing.

Abstract: A flat-type display comprising a first panel having electron-emitting portions; a second panel having an electron irradiation surface; and an electron-emitting-portion driving circuit for driving the electron-emitting portions, wherein an electron-emitting-portion cutoff circuit is provided between the electron-emitting portions and the electron-emitting-portion driving circuit for preventing a discharge between the electron-emitting portions and the electron irradiation surface.

Abstract: A method of forming flexible communications wire for use in Local Area Networks is disclosed. A plurality of individual metal strands are formed into a central conductor. The central conductor is then compressed and/or heated to bond adjacent strands together and to reduce the diameter of the wire.

Abstract: Spectacles with replaceable lenses comprises a frame constituted by a pair of rims joined together by a central portion or bridge, two temples connected to said frame by connecting members and hinges; means for clasping interchangeable lenses provided at the central portion of said spectacles frame and at said connecting members, each of said clasping means comprising a seat in said central portion adapted for receiving and engaging a first portion of an interchangeable lens and a pliers-shaped device in said connecting members for nipping a second portion of said interchangeable lens.

Abstract: A semiconductor memory cell comprising a first transistor for readout, a second transistor for switching, and having a first region, a second region formed in a surface region of the first region, a third region formed in a surface region of the second region, a fourth region formed in a surface region of the first region and spaced from the second region, a fifth region formed in a surface region of the fourth region, and a gate region, wherein when the semiconductor memory cell is cut with a first imaginary perpendicular plane which is perpendicular to the extending direction of the gate region and passes through the center of the gate region, the second region and the fourth region in the vicinity of the gate region are nearly symmetrical with respect to a second imaginary perpendicular plane which is in parallel with the extending direction of the gate region and passes through the center of the gate region.

Abstract: A sun visor includes a visor assembly having an illumination device. The visor assembly further includes a trim bezel tray, backplate, and lamp/mirror lid. The trim bezel tray has a battery holder and at least one receiving portion molded as an integral part of the bezel. Access to the trim bezel tray is made possible by hingedly opening the trim bezel tray and backplate of the visor. A replaceable battery is placed within the battery holder. In a preferred embodiment, the illumination device includes an illumination source and a lightpipe with a lens attached to each end. The lightpipe assembly eliminates wiring from the installation and the replaceable battery eliminates the need for a remote power source. In another embodiment, the illumination device includes at least one illumination source positioned in the receiving portions of the bezel. The illumination source is in communication with the battery through electrically conductive wires.

Abstract: A variable oil ring compression mechanism provides for real-time cyclic variation of piston ring tension in an operating internal combustion engine. A cam is situated in the gap of a piston oil control ring, the cam affixed to a shaft secured to a pivot plate positioned within the body of the piston, wherein the pivot plate is adapted to oscillate in a follower-style rocking motion responsive to the rotary movement of a connecting rod boss positioned in close proximity with the plate. In a preferred form, the cam is situated between ends of an expander ring positioned between oil scrapper rails in the bottom groove of the piston.

Abstract: A sample solution is sent into a concentration column through a three-way joint and a three-way switching valve to trap and concentrate the sample components on the concentration column, followed by injecting the sample solution into an injector by operating a first dilution solvent pump. When a large volume of the sample solution is to be sent or when the sample solution has a high solvent strength, trapping and concentration on the concentration column may be facilitated by replacing the sample solvent with a second dilution solvent by allowing the second dilution solvent to flow into the three-way joint after setting the flow rate of the second dilution solvent from a second dilution solvent vessel to a prescribed flow rate using a second dilution solvent pump.

Abstract: An ADC having a sparkle suppression capability equivalent to that of a full bit Gray encoding method and preventing criss-crossing of interconnections nor an increase of the pipeline delay, wherein a resistor string for generating reference voltages to be compared with an analog input signal is folded 2n times or a multiple thereof corresponding to the number n of most significant bits of the output bit ADB of the related ADC. It has a first encoder for encoding the most significant n bits and outputting a Gray code, second encoders for encoding least significant bits and outputting the same, a first output circuit for converting the Gray code output from the first encoder to a binary code and generating most significant n bits, and a second output circuit for generating least significant bits by using the digital code generated by the first output circuit and the output of the second encoder.

Abstract: An ultrapure water trap is provided for retaining condensed water of water vapor which is formed in a TC oxidative reaction part, and a passage is so connected that an automatic sample injector can collect ultrapure water from the ultrapure water trap for injecting the same into the TC oxidative reaction part. The automatic sample injector dilutes ordinary pure water which is outside this apparatus with the ultrapure water which is retained in the ultrapure water trap, thereby preparing a test solution having ultralow carbon concentration of not more than 50 ppbC in the interior of a TOC meter.

Abstract: An audio system for playing recordings of audio programming includes a relatively large display device on which contextual information about the audio programming may be displayed. The contextual information is recorded on the same recording medium as the audio programming and may include any textual information or graphic images related to the audio programming or the artists who produced it. Preferably, the audio system is a personal, portable audio system which is battery-operated and which reads mini-discs.
