Title: Image forming device
Inventor: SEKIGUCHI ATSUSHI
IPC: G03G15/00
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To control image forming conditions so that not only color stability is improved but also an ideal line image is obtained by fixing the amount of toner attaching onto an image carrier while coping with every environmental change, too. SOLUTION: The image forming device which forms an image by attaching toner onto the image carrier 10 is provided with a patch forming means which forms a test solid patch and test line patch on the image carrier 10, and a detecting means which detects the amount of the attachment of the test solid patch, formed by the patch forming means, and the width of the line of the test line patch. First, the amount of the attachment of the solid patch is controlled by controlling the circumferential velocity ratio of a developer carrier 141 to the image carrier 10 according to the detection of the amount of the attachment of the toner of the test solid patch. Then, the width of the line is controlled by controlling a writing laser power according to the detection of the width of the line of the test line patch.

Title: Optical information recording and reproducing device
Inventor: NISHIKAWA KOICHIRO
IPC: G11B11/105
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording and reproducing device capable of making a track pitch narrower in addition to a super-high resolution reproduction by controlling the shape of a spot so that the optical detection sensitivity of a tracking error signal to be obtained from an information recording medium by a spot becomes maximum. SOLUTION: A luminous flux from a semiconductor laser 11 is converged as the spot 4 of an oblong circle whose length of the radial direction is shorter than the length of the track direction. The size of magneto-optical marks to be formed when a recording is performed by modulating an external magnetic field with a high frequency is not depended on the size of the spot but is determined by the modulation speed of the external magnetic field and the moving speed of a disk. That is, when the aperture of an objective lens and the wavelength of a light source are respective defined as NA, λ, the mark which is not larger than the resolution had by an optical head and whose size of the track direction is not larger than λ/(2 NA) can be framed by properly selecting the modulation speed of the external magnetic field and the moving speed of the disk.

Title: Manufacture of dielectric isolation substrate
Inventor: MATSUOKA SUSUMU
IPC: H01L21/762
Filed: 1988-08-19
Abstract: PURPOSE:To prevent development of chipping, etc., by forming a step through etching of a rear periphery of a single crystalline silicon substrate and forming a V-shaped groove for isolation at the same time and by forming an arched conferred shape at a periphery of the substrate at the time of completion. CONSTITUTION:A V-shaped groove 14 which serves as an isolation region is formed and a step 15 is formed at the same time at an opening section on an opposite surface. After an oxide film 11 is removed, an oxide film 16 for isolation is formed to form a polycrystalline silicon layer 17. When a side of a periphery is conferred to a projecting arched shape of a desired diameter, a vertex (c) of an arc moves to the side of the polycrystalline silicon layer 17 because of the step 15. When the V-shaped groove 14 is polished and removed until its bottom is exposed, an end section (d) of the single crystalline silicon island does not make a sharp angle and forms an arc in this way.
