In a method of producing a radiation detector, an active matrix board is formed to include gate lines and data lines arranged in a two-dimensional lattice shape, a plurality of high-speed switching elements provided to respective lattice points and connected to the gate lines and the data lines, picture element electrodes connected to source electrodes of the high-speed switching elements, and charge storage capacitances disposed between the picture element electrodes and ground on a insulating base plate. Then, a converting layer is formed at upper portions of the respective picture element electrodes at a temperature between 300° C. and 800° C. to generate a pair of electron-hole by absorbing light or radiation. The active matrix board is formed of a poly-silicon process board.

An engine for vehicle includes an oil hydraulic automatic transmission for changing the change gear ratio by control of an oil pressure. The oil pressure control unit of the transmission includes a plurality of control valves for controlling the oil pressure, and is mounted to an upper portion of a crankcase. A power transmission shaft interlockedly connected to a counter shaft and having an axis parallel to the counter shaft is disposed on the lower rear side of the counter shaft, and a drive bevel gear on the power transmission shaft and a driven bevel gear are meshed with each other on the rear side of the axis of the power transmission shaft. The resulting configuration eliminates the need for a special measure to protect the oil pressure control unit, and prevents interference of the driven bevel gear with the gear speed change mechanism.

A lost motion mechanism that biases a free rocker arm of a lift-amount changing member capable of lifting a valve in a direction to abut against a cam includes a spring accommodated in a support portion. The support portion is a recessed portion integrally formed on a camshaft holder below the free rocker arm. The vertical dimension of an engine is reduced as compared with a case where the support portion is provided above the free rocker arm. A camshaft cap supports the camshaft and a bolt that fastens the camshaft cap to the camshaft holder are not required.

This invention relates to a magnetic recording medium having a structure in which an undercoating film, a magnetic thin film, a protective film, and an organic film are stacked on a substrate in the order named. Since the protective film contains carbon and silicon and a portion of silicon in at least an interface in contact with the organic film consists of a silicon oxide, the surface of the magnetic recording medium is not degraded even by frequent contact with a magnetic head upon driving or stopping of the magnetic recording medium. This invention also relates to a method of manufacturing the same.

A two-dimensional image detector of the present invention includes: an active matrix substrate equipped with charge storage capacitors and TFTs; and an opposing substrate equipped with a semiconductor substrate. The two-dimensional image detector is formed by adhering the active matrix substrate and the opposing substrate to each other with an anisotropic conductive adhesive agent. With this structure, since a semiconductor layer is not required to be deposited on the active matrix substrate where the TFTs are already formed, it is possible to use CdTe, CdZnTe, etc. The use of CdTe, CdZnTe, etc. as a material of the semiconductor layer having photoconductivity allows the two-dimensional image detector to show good response and to deal with the dynamic images.
