Title: Method and device for master optical disk exposure control
Inventor: ITO YUJI
IPC: G11B7/26
Filed: 1991-07-05
Abstract: PURPOSE:To prevent the occurrence of a disturbance on an optical axis caused by the existence of a foreign object on a master optical disk and to perform a high quality exposure for the disk by monitoring the level of the total amount of reflected light from the master disk such as a glass master disk and controlling the transmission of optical axis error signals to an optical axis controller in accordance with the level. CONSTITUTION:An optical axis error detecting circuit section 11 generates electrical signals and optical axis error signals in accordance with the error of the current optical axis position against an initial value of the optical axis position and simultaneously generates reflected light total amount signals and inputs them to an S/H circuit 12 and a level detecting circuit 13, respectively. The circuit 13, to which reflected light total amount signals are inputted, a reference voltage, which is slightly smaller than the total amount of reflected light, is set as a reference value under the condition in which no foreign object exists on the glass master disk. When the total amount of reflected light is larger than the reference value, a high potential signal, i.e., an 'H' is outputted. Conversely, if the amount is smaller, an 'L' is outputted. Since the reflected components normal to the disk become smaller if a foreign object exists on the disk, an optical axis is properly controlled.

Title: Electronic component mount board using film base
Inventor: SATAKE HIROAKI
IPC: H01L21/60
Filed: 1990-07-19
Abstract: PURPOSE:To prevent the problem such as creases, cracks, or peeling from arising in a die even when the film base is repeatedly wound around a reel, for example by forming a die pad in a state that one of its diagonals is almost orthogonal to the longitudinal direction of the film base. CONSTITUTION:In an electronic component mount board 10, one diagonal 13 of a die pad 12 is almost orthogonal to the feed direction of film base 11. Therefore, when substrates 10 are wound one after another around a reel or around the substrate 10 or the base 11, a square-shaped die pad 12 is located on the reel or on the already wound substrate 10 or the base 11 in the order of one apex 12a, two diagonal apexes 12b, and the remaining apex 12a. This acts to disperse force received upon winding or the like so that the problem such as creases, cracks, or peeling can be prevented from arising in a die pad even when the base is repeatedly wound around a reel.

Title: Character broadcast receiver
Inventor: OSAWA HIROSHI
IPC: H04H60/13
Filed: 1985-08-30
Abstract: PURPOSE:To make a character broadcast screen as well as a television broadcast screen easy to see by compressing the character broadcast screen from an original display size to display it and displaying the television broadcast screen on the remainder part. CONSTITUTION:When the first selecting switch 34 is turned on, a clock pulse f2 from a screen compressing reference oscillator 30 is applied to a column address counter 26. Since this pulse f2 has two-fold frequency f1 of a reference oscillator 28, character information data corresponding to one horizontal scanning is read out from a display memory 22 in a time which is a half of the time for all screen display. Since the output timing of an overflow signal B2 outputted from the counter 26 is shortened to a half in accordance with this read, the period when a timing signal T2 outputted from a system control part 38 in response to a horizontal synchronizing signal is in the high level is reduced to a half. Thus, the character broadcast screen is compressed and displayed on the left half of the screen of a CRT 18.
