Title: Optical disk device
Inventor: SAKAKIBARA SHIRO
IPC: G11B7/09
Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain an optical disk device capable of performing a stable tracking control by preventing the decrease of the control gain of a tracking servo loop even for an optical disk with narrow track pitch. SOLUTION: In a disk reproducing device, the information regarding the track pitch is detected by a track pitch detecting means 7 prior to the tracking control using a tracking error signal 4. And, the gain of a GCA 8 is set in accordance with the detected track pitch. Thus, the stable tracking control can be attained without lowering the control gain of the tracking servo loop even when the track pitch is narrower than that of the disk specification.

Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To provide the method of manufacturing a wiring board with which a solder bump is planarized by adhering a reinforcing plate with a wiring board main body under reduced pressure. SOLUTION: A wiring board main body 6 and a reinforcing plate 2, which are superimposed via an adhering sheet 10A and a bump flattening jig 13 are arranged on the adhering surface 11A of an adhering jig 11.

IPC: B29C49/06
Filed: 1991-12-04
Abstract: PURPOSE:To obtain a container, in which no whitening develops and which has excellent transparency and favorable heat resistance, by a method wherein a blow-molded body is shrunk by controlling its inner pressure under the condition being held at the temperature higher than the crystallization temperature of crystalline plastic and, after that, second stretch blow molding is further performed. CONSTITUTION:A preformed body 80, at least the upper end part of the. cylindrical part of which has multilayered structure consisting of crystalline plastic and amorphous plastic, is produced. Next, by stretch blow molding the body held within a temperature range from lower than the glass transition temperature of the amorphous plastic by 5 deg.C to one higher than that by 10 deg.C, a primary blow molded body 81, the dimensions of which are larger than those of an aim container, is formed. By controlling the inner pressure of the primary blow molded body 81 held at the temperature higher than the crystallization temperature of the crystalline plastic, the primary blow molded body is shrunk to the dimensions, which are smaller than the dimensions of the aimed container. The resultant shrunk molded body 82 is stretch-blow-molded secondarily under the condition being held at the temperature, which is below the glass transition temperature of the amorphous plastic, in order to obtain a heat resistant container 83.

Title: Video signal processing method and processing circuit
Inventor: ONODERA JUNICHI
IPC: H03L7/14
Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a processing circuit that can correctly adjust a phase even when the amplitude of a color burst signal is distorted. SOLUTION: An input signal to a PLL circuit generating a sampling clock is generated by slicing a color burst signal of a composite color signal or a color signal at a 0 level, the composite color signal or the color signal is converted into a digital signal by using the sampling clock, a video signal at each sampling point whose phase is adjusted through an interpolating point arithmetic operation and a chrominance signal or a luminance signal is demodulated from the video signal at the sampling point whose phase is adjusted. Since the slice level of the color burst signal used by the PLL circuit is selected to be 0 level, even when the color burst signal whose amplitude is distorted is received and since the phase is entirely uniform, the sampling phase is constant to conduct phase locking with correct amplitude.  However, when the slice level is set to 0, since the demodulation axis of a signal is fixed to 90-degrees, the interpolating point arithmetic circuit generates the signal on the demodulation axis at a desired phase and the signal is given to a color demodulation circuit.
