Title: A/d converter
IPC: H03M1/18
Filed: 1992-03-26
Abstract: PURPOSE:To reduce odd number order distortion generated in the track mode by providing a switch closed in the track mode of a track hold circuit and opened in the hold mode to the A/D converter. CONSTITUTION:Since a switch 6 is closed in the track mode, an input 22 of a programmable gain amplifier 2 is connected to a common potential point via the switch 6. In this case, a load impedance 3 of a track hold circuit 1 is RL+RS (RL is a resistance of a resistor 3 and RS is a resistance when the switch 6 is closed). That is, the load impedance in the track mode is always RL+RS in the output state of the circuit 1. Thus, even when the output resistor of the track hold circuit 1 is in existence, odd number order distortion caused in the track mode is reduced.

Title: Erasing power setting circuit and optical disk recording and reproducing device
Inventor: TAKIGUCHI TAIZO
IPC: G11B7/00
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To improve the erasing characteristics and to avoid the adverse effect on adjacent tracks by obtaining an optimum recording power and setting the power, which is obtained by multiplying a replacing coefficient α to the optimum recording power, as the optimum erasing power of an optical disk. SOLUTION: The optimum recording power is the power in which an asymmetry becomes zero. The asymmetry is obtained by the method described below. In an optical disk format, a VFO region and a data region are provided within a sector. At the beginning of the data region, repeated pits of asymmetry generating data used as long marks with a recording width 6T are recorded, for example. From the obtained reproduced waveforms, an asymmetry Asym of each pit is computed from the equation below: Asym=(D-C)/B where C is the central value of the reproduced waveforms by the short marks in the VFO region, D is the central value of the reproduced waveforms by long marks and B is the amplitude. The optimum recording power is obtained from the asymmetry value and the optimum erasing power is computed by multiplying the coefficient α (0.77<=α<=0.88) to the optimum recording power.

Abstract: PURPOSE:To restrain the strain of a film and a copper foil from being opened, to prevent the dislocation of a lead and to enhance the positional accuracy of the lead of a tape carrier by a method wherein a frame-shaped metal-foil pattern is formed near a device hole region. CONSTITUTION:In the case of a three-layer film carrier in which a film 1, about 50 to 125mum thick, made of a polyimide and a copper foil 2, about 17 to 35mum thick, plated with tin to be thin on the surface are bonded via adhesive, the copper foil 2 is left all over the surface excluding a device hole 3 in which an IC chip is situated at an ILB operation and without removing parts other than a lead formation part. A copper foil 4 is patterned and formed on the surface by leaving only parts of leads 4A proper; a copper foil 5 which is used to prevent a strain from being opened is left all over the surface on the rear side. Thereby, the bonding area of the thin film to the copper foil is not changed so much, and it is possible to prevent the dislocation of the leads from being caused by an etching operation.

Title: Wiring formation method
Inventor: SUMI HIROBUMI
IPC: H01L21/3205
Filed: 1991-03-08
Abstract: PURPOSE:To enhance the bond properties onto the insulating film of a high melting point metallic base wiring layer formed by the blanket CVD process. CONSTITUTION:A W wiring layer 11 is formed in two stages, i.e., the first W layer 9 to be a bonding layer is formed by the bias sputtering process while the second W layer 10 in excellent stepped part coverage is formed on the layer 9 by the CVD process. At this time, the first W layer 9 is coated to an extent not to bury the contact holes 8 made in the interlayer insulating film 7 of a MOS transistor. In such a constitution, the bond properties onto the interlayer insulating film 7 can be enhanced by the first W layer 9 thereby enabling not only the peel-off of the wiring layer 11 to be avoided but also the barrier properties in the contact parts with source/drain regions 5 to be enhanced. Through these procesures, the inner stress and the sheet resistivity in the first W layer 9 can be lowered by the bias impression during the film formation time than those in the case of no bias impression thereby enabling the reliability upon the wiring to be improved.
