Title: Polyester resin molding material
Inventor: MINAMIHAMA MASANORI
IPC: C08L67/00
Filed: 1981-03-19
Abstract: PURPOSE: To improve the thermal discoloration resistance, by adding, at specified ratio, ε-caprolactam and calcium carbonate to a polyester resin molding material containing a normally liquid crosslinking agent.  
     CONSTITUTION: In a polyester resin molding material prepared by adding a curing agent, filler, lubricant, coloring agent and additive to a polyester resin, iodine value 80W110, containing 5W25wt% normally liquid crosslinking agent; 8W16wt% polyester resin, 0.2W1wt% ε-caprolactam and calcium carbonate, average particle size 5W7μ, are mixed. It is required that the polyester resin used has an iodine value of 80W110. A convertional polyester resin, iodine value 60W70, is not suitable because of its marked thermal discoloration. It is required  that the crosslinking agent be liquid at normal temperature. If the agent is  solid, the productivity is markedly decreased because the amount of the resin  which can be added is small.

Title: Information recording medium
Inventor: SUZUKI KATSUMI
IPC: G11B7/2433
Filed: 1987-02-24
Abstract: PURPOSE:To obtain an information recording medium which has high stability of recording and recording level and obviates generation of defective initialization and partial erasing by forming a recording layer of an alloy having a compsn. expressed by In50Sb50-xMx where M is an element belonging to a group IIB and (x) is larger than 0 and below 15atom.%. CONSTITUTION:This information recording medium has a substrate 11 and the recording layer 13 to and from which information is recorded and erased by the phase change which takes place when a light beam 18 is projected thereon. When the light beam is projected on the recording layer of such recording medium, the alloy of the compsn. expressed by In50Sb50-xMx separates to In50-xSb50-x and InxMx where InxMx exists by being dispersed into the stable crystalline In50-xSb50-x; in addition, this InxMx is stable in the amorphous state and, therefore, the stability of the recording is high. The InxMx generated by the phase sepn. causes the phase change between the crystalline phase and the amorphous phase by changing the conditions for projecting the light beam and, therefore, the high recording level is obtainable. Since the phase change rate of this InxMx is high, the initialization and erasing are speeded up and the defective initialization and partial erasing are suppressed.

Abstract: PURPOSE:To obtain a large output by a simple structure by a method wherein a plurality of semiconductor cells are laminated in the same direction as the direction of the lamination of clad layers and active regions so that the active regions are arranged in nearly a straight line. CONSTITUTION:Each cell (C) has a P type active layer 13 between the clad layers 12 and 14 and the active region 21 only in the thickness of this layer 13.

Such a manner enables to facilitate the synchronization of the oscillation of each cell. Further, since the cells a are laminated in the direction of the thickness of each layer, the distance between active regions of each cell can be reduced. Therefore, the stretch of an emitted beam becomes narrow thereby, and accordingly the titled device of a large output can be easily obtained.

Abstract: PURPOSE:To obtain a developing device of high image quality where density variance does not occur, by providing a means which coats an electrostatically charged developer on a developer carrier and a layer thickness control means which controls the layer thickness of this developer. CONSTITUTION:The layer thickness of a coated developer 19 on the surface of a developing roller 22 is 50-150mum and is thicker than a prescribed value and is somewhat uneven.

Filed: 1993-03-02
Abstract: PURPOSE:To dry-etch an X-ray absorbing metal layer on an X-ray film while maintaining a high selection ratio to the film in a manufacture of a mask for X-ray lithography. CONSTITUTION:A W film 3 (X-ray absorbing metal layer) formed on a SiN film 2 (X-ray transmitting film) is etched using a S2F4 gas. The W film 3 is removed in the form of WFx, and an S-deposited layer 6 is formed on the side wall surface of a pattern by S (sulphur) dissociated from the S2F2. When the underlying SiN film 2 is exposed, the S atom in a plasma couples with the dangling bond of the N atom having appeared on the exposed surface, whereby a sulphur nitride deposit layer 7 mainly composed of polythiazyl (SN)x is formed. By the surface protection effect of the sulphur nitride deposit layer 7, the high selectivity for the ground is achieved.

Title: Dropout counting circuit
Inventor: MIYOSHI HIROAKI
IPC: G11B7/00
Filed: 1989-02-23
Abstract: PURPOSE:To measure the number of times of generation of a microdropout efficiently by positioning the leading edge of the output of a waveform shaping circuit in a window pulse when the shape of a bit is normal. CONSTITUTION:The waveform of a signal which is read out of an optical disk is shaped by a waveform shaping circuit 1 and the leading edge of the output of the waveform shaping circuit 1 is regarded as reference time to generate the window pulse which varies in pulse width from the minimum cycle period elapse to the maximum cycle period elapse of the output of the waveform shaping circuit 1 when the shape of the pit is normal. When the leading edge from the waveform shaping circuit 1 is not within the window pulse, a pulse generating circuit 7 generates a pulse. Then a generation rate measurement counter 8 counts output pulses of the pulse generating circuit 7 at a specific cycle period. Consequently, it is judged that a microdropout which causes trouble as to a reproduced signal is generated from the counted value of the generation rate measurement counter 8.
