Filed: 1993-12-28
Abstract: PURPOSE:To obtain a uniform and excellent quality SiO2 protective film by using an organic oxysilane as a raw material and Ar, He or NH3 as an assistant reaction gas and forming the protective film by plasma CVD method.

Further, resolving power can be adjusted by changing the mixing ratio of the contrast medium. Then, X-ray inspection is performed. X-rays to be used has intensity sufficient to transmit through a thick external sheath 24. The tensile bodies 20 themselves are not formed into images but the layer 30 containing the contrast medium is formed into an image. By this constitution, the deformation, buckling and breakage of the tensile bodies 20 can be easily observed and inspected.

Title: Video signal processor
Inventor: TANJI ICHIRO
IPC: H04N9/64
Filed: 1994-12-28
Abstract: PURPOSE: To prevent the lowering of image quality and grade by varying the gain of a variable gain image width circuit and performing a correction so that a contour signal level may not exceed a reference value. CONSTITUTION: In a detail signal generation circuit 12, a detail signal DTL is generated from digital color signals DR, DG and DB. A detail signal correction circuit 14 outputs the signal DTL 1 to addition circuits 16R, 16G and 16B via a variable gain amplifier circuit 15, adds the signal to the signals DR, DG and DB and emphasizes the contours of these signals. At this time, the circuit 14 varies the gain of the circuit 15 and performs a level correction so as not to change the peak level of the signal DTL to a stipulated value or more. At the time of varying the gain, the gain is varied for a prescribed period partial shape so that the waveform of the signal DTL may be preserved in its original shape in the rise and fall parts of the level exceeding the stipulated value.  Thus, a higher harmonic can be reduced and the generations of a false signal and an overshoot can be evaded when the level correction of the signal DTL is performed.

Abstract: PURPOSE:To form a compact, thin optical head by providing a concave mirror having a filter so that the light from a semiconductor laser is reflected in the direction of about 90 degrees with respect to the emitting direction of the light and a spot is formed on a light recording medium. CONSTITUTION:The shape of a concave mirror 2 has a spheroid surface or a curved surface which is approximate to the spheroid so that the light emitted from a semiconductor laser 1 is reflected in the direction of about 90 degrees and the focal point is focused on a light recording medium 5.

A part of the light emitted from the semiconductor laser 1 is reflected, and a part of the remaining light is transmitted. A photodetector 4 is formed as a unitary body with the concave mirror 2. The light is modulated in amount of light with pits formed in the light recording medium 5 and reflected. The light transmitted through the concave mirror 2 is detected. In this way both operations of a rise-up mirror and an objective lens are performed with one concave mirror 2. Thus, the number of optical parts is decreased, and the optical head can be made compact and thin.
