Prevented is the reliability loss in phase change optical recording media during high-temperature storage, and also prevented is the phenomenon of self-erase by which a part of record marks having been formed in the media are erased due to the lateral heat diffusion into the recording layer while recording laser beams are irradiated to the media. The optical recording medium disclosed has a recording layer of a phase change type and is applied to driving units for overwriting it at a linear velocity of V.sub.0. The medium is so designed as to satisfy the requirement of 1

In a phase change-type optical recording medium of absorption coefficient control structure used by land/groove recording system, difference in reproduction characteristics between the land and the groove is minimized while ensuring sufficient output of the tracking signal. In the optical recording medium of the present invention, light absorption coefficient at the wavelength of said recording/reproducing beam is such that: Ac/Aa.gtoreq.0.8 when light absorption coefficient in crystalline region is Ac and light absorption coefficient in amorphous region is Aa; relation between groove width W.sub.G and land width W.sub.L is such that: x=2W.sub.G /(W.sub.L +W.sub.G).gtoreq.1.03; and the relation: .lambda.max.sup.i

The present invention aims to ensure strength of a thin-walled sintered magnet. A sintered magnet is a ferrite sintered magnet made by sintering a magnetic material. A magnetic powder mixture obtained by mixing magnetic powder with a binder resin is injection-molded into a mold with a magnetic field applied thereto to produce a molded body, which is then sintered to produce the sintered magnet. The sintered magnet has a thickness of 3.5 mm or less in the position of center of gravity thereof. The sintered magnet has a surface roughness Rz of 0.1 μm or more and 2.5 μm or less. The surface roughness Rz is a 10 point average roughness.

This invention provides a sticking tool capable of sticking a sticking matter to a sticking target position easily and accurately and executing the sticking operation smoothly. This sticking tool includes a casing body 2, a sticking tool main body 3 which is moved in the direction of being projected from and submerged into the casing body 2 by a pressing force F1 applied at the time of sticking operation so as to stick a patch P to the peripheral portion Xb of a punch hole Xa and an alignment portion 7 for determining a relative position of the sticking tool main body 3 to the punch hole Xa and the alignment portion 7 is so constructed to be capable of moving between an overlapping position (Q) which substantially overlaps the peripheral portion Xb of the punch hole Xa and a retraction position (R) not interfering with the sticking tool main body 3 and paper X.

An electrical testing substrate unit includes a multi-layer ceramic substrate formed of mullite and a borosilicate glass as predominant ceramic components. In the multi-layer ceramic substrate, the borosilicate glass contains an alkali metal oxide in an amount of 0.5 to 1.5 mass %. The multi-layer ceramic substrate has a mean coefficient of linear thermal expansion having a value of 3.0 to 4.0 ppm/° C. between −50° C. and 150° C. A thermal expansion coefficient, α1, of the multi-layer ceramic substrate as determined at a particular temperature and a thermal expansion coefficient, α2, of a to-be-tested silicon wafer as determined at the same temperature silicon satisfy a relation: 0 ppm/° C.

A liquid crystal display device includes a pair of substrates composed of a first substrate and a second substrate, which are disposed opposite to each other with a liquid crystal layer interposed therebetween; a plurality of pixels arranged in a matrix; reflective layers that are provided on the second substrate and reflects incident light from the first substrate side; a plurality of sub-pixels constituting each of the plurality of pixels; color filters on which colored layers having different colors are arranged, each of the colored layers corresponding to each of the sub-pixels; and an illumination unit provided at an outer surface side of the second substrate. The liquid crystal display device is a transflective liquid crystal display device for displaying images through a reflective region and a transmissive region, which are provided in each of the sub-pixels. The reflective region of each sub-pixel is a region for black and white display or monochrome gray-scale display, the transmissive region is a region for color display in the pixels, and reflectance of the reflective region of each sub-pixel is different for each of the sub-pixels having different colors.
