A recording film is formed by a vacuum film formation process. The recording film contains a substance which is thermally decomposed when a recording laser beam is irradiated thereto. When the substance is thermally decomposed by irradiation of the recording laser beam, a substance generated by the thermal decomposition is precipitated within the recording film, and therefore a change in complex index of refraction is caused predominantly over the raising deformation in the recording film. As a result, information is recorded in the recording film while causing almost no raising deformation of the recording film.

Optical information recording medium and manufacturing method thereof

A semiconductor device with a current detecting function in which in place of an external resistor for detecting an operation current such as drain current or collector current of a device such as an FET or bipolar transistor, a probe electrode is formed in proximity to the device depletion layer to connect therethrough with the device channel to generate a probe voltage corresponding to the operation current.

Semiconductor device with current detecting function

A thermoelectric generating composite functioning apparatus used as a glow plug in a diesel engine has sintered semiconductor elements respectively formed in the shape of a bar of N-type and P-type thermoelectric semiconductor materials. The N-type and P-type semiconductor elements are provided oppositely with a gap between them, and their end portions are put in mutual contact to form a P-N junction. A low thermal conductivity insulator is filled in the interval between the N-type and the P-type semiconductor elements. The N-type and P-type semiconductor elements provided in the P-N junction state are contained through the insulator in a housing. Lead terminals connected to the N-type and P-type semiconductor elements are formed in the housing. The apparatus may provide heat to the combustion chamber, or generate electricity from the heat in the combustion chamber.
