Title: Semiconductor device
Inventor: KOMORI SHIGEKI
IPC: H01L21/3105
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a polishing prevention pattern that can increase the planarity of an element forming region after polishing due to CMP(chemical mechanism polishing) method. SOLUTION: A loop-shaped element formation region dummy 3 is formed in matching with the shape of an element forming region 2 and is formed into a loop shape with fixed width at a fixed distance from the outer edge of the element formation region 2, thus preventing formation of large gap between a part corresponding to the extension line of the clearance between polishing prevention patterns and the long distance between the element formation region 2, and the polishing prevention pattern, suppressing large pressure which is locally applied to the end part of the element forming region 2 being generated by allowing polishing cloth to bend. As a result, a semiconductor device is obtained where planarity of the surface of the element formation region is maintained, since there is no part which is locally etched in large area.

Title: Disk cartridge library device
Inventor: ONO IWAO
IPC: G11B17/26
Filed: 1989-11-10
Abstract: PURPOSE:To attain accurate and smooth loading and unloading of a cartridge even when there is any position deviation between a holder and a containing slot by fixing a holder support means and a guide roller fixed to a prescribed height position. CONSTITUTION:Guide rollers 24, 25 are provided to a prescribed height of a support 20 fixed to a cartridge 10. When the vertical movement of the holder 10 with a detection means and a movement control means is stopped, a deviation of the height between cartridge outlet and inlet is caused between the holder 10 and a container slot 2 due to the upside down of the holder 10 and the size difference between holder pockets 12, 14 of the like. In this case, the tip of the cartridge fed from the holder pockets 12, 14 is press contact onto the rollers 24, 25 and the lower face is abutted on the rollers, thereby being guided to the exit and entrance of the slot 2. Thus, even when a position deviation takes place, the cartridge is accurately and smoothly loaded and unloaded.

Title: Signal processing circuit
Inventor: TANABE TAKANARI
IPC: G11B7/005
Filed: 1990-11-02
Abstract: PURPOSE:To apply sharp waveform shaping to different signals almost symmetrically by detecting a change in an input signal, extracting only one polarity component in the change with a half wave rectifier circuit, and synthesizing it with the input signal at a synthesizing circuit. CONSTITUTION:A reproduction signal (a) inputted to an input terminal 11 is fed to a variation circuit 12 and a synthesis circuit 14. The circuit 12 differentiates the said reproduction signal (a) into a signal (b) and it is fed to a half wave rectifier circuit 13. The half wave rectifier circuit 13 suppresses the negative component of said signal (b) and passes only through a positive component to obtain a signal (c) and it is fed to the synthesis circuit 14. The synthesis circuit 14 adjusts the gain and phase of the said signal (c) and the said reproduction signal (a) and delays the phase of the signal (a) concretely and takes a difference between them to obtain a signal (d) and it is outputted from an output terminal 15. Thus, even when the leading edge and trailing edge waveform in the reproduction signal differs remarkably from each other, the signal is waveform-shaped almost symmetrically without a peak.

Title: Operating method for ferroelectric nonvolatile memory
Inventor: SUGIYAMA HISANOBU
IPC: G11C14/00
Filed: 1994-11-04
Abstract: PURPOSE: To realize a long term operation by suppressing the deterioration of a ferroelectric. CONSTITUTION: When a stored data is read out, only an electric field weaker than a coersive electric field is applied to the ferroelectric of ferroelectric capacitors 14, 15. Since the permittivity of ferroelectric varies depending on the polarization thereof, the potential appearing on a bit line depending on the coupling ratio between the capacitances of the ferroelectric capacitors 14, 15 and the bit line also varies depending on the polarization of the ferroelectric. Consequently, a stored data can be read out without migrating the charges stored in the ferroelectric capacitors 14, 15.
