Title: Production of information recording medium
Inventor: YABE MASAO
IPC: B41M5/26
Filed: 1987-02-04
Abstract: PURPOSE:To permit formation of a recording layer on a substrate by a coating method without dissolving the substrate by dissolving a dye into a solvent contg. a fluorine-substd. nitro compd. to prepare a coating liquid, then coating the coating liquid on the substrate and drying the coating, thereby forming the recording layer. CONSTITUTION:The coating liquid is prepd. by dissolving the dye into the solvent contg. the fluorine-substd. nitro compd. and thereafter, the coating liquid is coated on the substrate and the coating is dried, by which the recording layer is formed. More specifically, the fluorine-substd. nitro compd. to be used as the solvent has high solubility with the dye such as cyanine dye and, therefore, the coating liquid for forming the recording layer can be easily prepd. Since this compd. is inert to the substrate consisting of a plastic material such as polycarbonate, the dissolution of the substrate in the coating stage does not arise. The information recording medium having high performance is thereby produced without generating the loss of grooves on the substrate surface and the degradation in the reflectivity of the recording layer.

IPC: H05B41/392
Filed: 1991-01-28
Abstract: PURPOSE: To enhance a degree to which a light color point of light a lamp emits does not depend upon a value of luminous flux by adjusting both of an amplitude of a high-frequency pulse shaped current and a duty cycle. CONSTITUTION: In a circuit provided with a circuit I generating a high-frequency pulse shaped current having an amplitude from a power voltage and a modulator II for modulating the high-frequency pulse shaped current in a substantially rectangular wave shape at a modulation frequency and a duty cycle and suitable to turn on a low-pressure mercury discharge lamp IV by the high-frequency pulse shaped current, an amplitude of a substantially rectangular-wave modulated high-frequency pulse shaped current is adjusted by an amplitude adjustment circuit III. Thereby, a light color point of the lamp IV is almost independent of a value of luminous flux. When this circuit is provided with a modulation frequency adjustment circuit VI a range in which a light color point can be adjusted with respect to a selection value of luminous flux of the lamp IV can be increased and is made advantageous.

Title: Method for repairing pinhole in surface layer of casting
Inventor: MASE KEIJI
IPC: B22D29/00
Filed: 1993-02-15
Abstract: PURPOSE:To easily repair pinholes with certainty, further to prevent the pinholes from appearing at the machined surface on the surface of a casting, to improve the quality of the machined surface, and to eliminate inferior coating on the machined surface. CONSTITUTION:Shots, having hardness higher than that of a nonferrous alloy casting, being a work W, and also having an average grain size 50-150% of the size of the pinholes existing in the vicinity of the surface of the casting, are sprayed at >=80m/sec spray velocity onto the surface of the casting by means of a direct-press type blasting device 30, and the temp. in the vicinity of the surface of the casting is elevated to a value not lower than melting temp. Because the surface of the casting whose temp. is elevated to a value not lower than melting temp. is softened and the size of the shots is large, the pinholes can be smoothed and the pinholes within the surface depth whose temp. is elevated to a value not lower than melting temp. can be removed.

IPC: G11B17/32
Filed: 1988-02-08
Abstract: PURPOSE:To obtain head touch to be always stable by energizing a magnetic sheet towards a magnetic head with positive pressure and simultaneously sucking the magnetic sheet with negative pressure. CONSTITUTION:When a magnetic sheet 11 is rotated since the inclining surface 14a of a negative pressure generating member 14 is inclined so as to be separated much more from the magnetic sheet 11 in a lower flow, the negative pressure is generated and the magnetic sheet 11 is sucked to a magnetic head 13. Simultaneously, since an inclining surface 16a of a positive pressure generating member 16 is inclined so as to be close to the magnetic sheet 11 much more in the lower flow, the positive pressure is generated and the magnetic sheet 11 is energized to the magnetic head 13. Thus, when the positive pressure and negative pressure are simultaneously operated and further, the positive pressure generating member is satisfactorily adjusted, the stable head touch can be always obtained in the whole area of a head moving range.
