Patent number: 9336810Abstract: A method for manufacturing a glass substrate for magnetic disk is provided in which a glass is kept from being fused to a mold during press forming and shape processing to achieve a good circularity is efficiently performed. The method includes: a forming process of forming a disk-shaped glass blank by direct-pressing a molten glass by a pair of dies; and a shape processing process of performing at least one of inner hole formation and outer shape formation for forming a disk-shaped glass substrate by forming a cutting line on the principal face of the glass blank, followed by growing the cutting line to perform cutting. In the forming process, press forming is performed while the temperature of the pair of dies, over a period of time until a molten glass is separated from the die after coming into contact with the die, is set at a temperature lower than a glass transition point (Tg) and a mold release material is not attached to the surfaces of the pair of dies.Type: GrantFiled: April 27, 2012Date of Patent: May 10, 2016Assignee: HOYA CORPORATIONInventors: Hideki Isono, Hidekazu Tanino, Akira Murakami, Takashi Sato, Masamune Sato, Masaru Onishi

Patent number: 5781572Abstract: An optical wavelength stabilizing system including a laser diode for emitting signal light, a Peltier element for controlling a temperature of the laser diode, and a drive circuit for driving the Peltier element. The signal light is branched into two components by an optical coupler. In an optical path of one of the two components obtained by the optical coupler, there is inserted an optical filter having a portion whose transmittance continuously changes according to wavelength. The signal light component passed through the portion of the optical filter is detected by a photodetector. An output current from the photodetector is converted into a voltage, which is then input into a comparator. The comparator compares the voltage output from the photodetector and a reference voltage to input a voltage difference therebetween into the drive circuit.Type: GrantFiled: May 6, 1996Date of Patent: July 14, 1998Assignee: Fujitsu LimitedInventors: Yoko Tahara, Yoshinori Ohkuma, Masaru Onishi, Toshiyuki Masuko

Patent number: 5727087Abstract: In an image processor using image data compression coding of a fixed compression rate, the data of one color of image data is stored in a coding memory without coding, if compression coding is not necessary. If the compression coding is necessary, the data is coded by an encoder by compression coding with a compression rate of 4, and the coded data of four colors, i.e. cyan, magenta, yellow and black, are stored in the coding memory. Since the image data is compressed by a fixed compression rate, it is possible to estimate the quantity of data after compression. As a result, the coding memory can be used effectively, without using a fixed disc unit.Type: GrantFiled: March 21, 1995Date of Patent: March 10, 1998Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Narihiro Matoba, Masaru Onishi

Patent number: 5706103Abstract: An image processing device comprises an encoder for encoding inputted image data in the form of fixed length compression. The encoded data encoded in the form of the fixed length compression by the encoder is stored in a hard disk through an encoded data buffer which is a toggle buffer. Accordingly, the image data can be stored in the hard disk at a constant speed, and a capacity of the encoded data buffer can be minimized since the data amount after data compression is decided. As a result, it is not necessary to provide a semiconductor memory corresponding to storage of one screen, so that a low cost image processing device is obtained.Type: GrantFiled: March 28, 1995Date of Patent: January 6, 1998Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Narihiro Matoba, Masaru Onishi

Secondly, the image data are subjected to a color conversion process by the use of color conversion parameters having different values from one another, and a plurality of processed images are displayed by the display device. Moreover, from among the processed images being currently displayed there is selected a processed image having substantially the same colors as the image recorded by the hard copy unit, to thereby set the value of the color conversion parameter. Subsequently, a color conversion parameter representing an inverse conversion to the color conversion by way of color conversion parameter which has been set is set into the hard copy unit to thereby print the image based on said image data.Type: GrantFiled: April 14, 1994Date of Patent: August 22, 1995Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kenichiro Oka, Masaru Onishi
