A front end signal processing method and apparatus for processing a signal from an image sensor are provided for readily clamping a black level, improving the manufacturing yield, and reducing the power consumption. A luminance detector/digitizer receives a sensor output signal from an image sensor, detects luminance information included in the sensor output signal, and generates a digital luminance signal representative of the detected luminance information. A digital processor receives the digital luminance signal, and multiplies the digital luminance signal by a predetermined gain code to generate the multiplication result as a front end processed signal output. An optical black clamp receives the digital luminance signal from the luminance signal detector/digitizer and supplies a feedback signal produced from the digital luminance signal to the luminance signal detector/digitizer to clamp a black level of the luminance signal to a constant value.

Propylene/ethylene block copolymer composition for exterior automotive part

For providing a cleaning technique capable of removing metal contamination at a low temperature and in a short period of time, an aqueous solution containing 0.1 to 15% by weight of hydrochloric acid, 0.01 to 0.3% by weight of hydrofluoric acid and 0.1 to 15% by weight of hydrogen peroxide is used as a cleaning solution for cleaning a semiconductor substrate after forming a gate electrode of a polymetal structure on the semiconductor substrate.

Fabrication method for semiconductor device

A joined metal-resin plate body having a metal plate (,) and a resin plate (,) joined together, in which an insert member having a through-hole therein is embedded in the resin plate. The insert member is in close contact with the resin of the resin plate in the outer periphery of the insert member except for the faces where the through-hole opens. The metal plate has a metallic joining member (,) adhered thereto. The resin plate is joined to the metal plate with the aid of the joining member fitted in the through-hole. The insert member and the surrounding resin have elastic stresses (F,, F,), which give rise to a sufficient joining strength among the joining member, the insert member and the resin plate. The stress of the surrounding resin is due to elastic deformation. The amount (V,-V,) of the elastic deformation is smaller than the amount (V,) of deformation of the insert member which can give rise to an elastic stress (F,) of the insert member.

Method of making a swing actuator

A swing-type actuator for use in a magnetic disk unit which includes a magnetic head; an arm supporting the head and a movable coil acting in a magnetic circuit. The movable coil is composed of a coil bobbin having a conductive wire wrapped around the bobbin. The bobbin is produced by injection molding into the bobbin of a thermoplastic resin having a flexural modulus of at least 8&times;10,kgf/mm,and a heat deformation temperature of at least 200&deg; C. under a load of 18.6 kg/cm,. A junction member to which the arm and the bobbin are integrally fixed by insert molding is made of the same resin as the bobbin or another thermoplastic resin being selected from the group consisting of a polybutylene terephthalate resin, a polyphenylene sulfide resin, a polyamide, a polyether ether ketone resin and thermotropic liquid crystal polymer.
