Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve an overwriting erasure ratio by irradiating a crystal space part with a laser beam of a first power level, then irradiating the same with a laser beam of a second power level different from the first power level at the time of forming the crystal space part. SOLUTION: The crystal space part is formed by irradiating this part with the beam formed as pulses between the peak level (Pc1) lower than the recording power level for making a recording layer amorphous and a bottom power level (Pc2) lower than the Pcl. At least either of the pulse of Pc1 and the pulse of Pc2 is shorter than the time when the full-width at half value of the laser beam passes one point above the medium. The pulse lengths of Pc1 and Pc2 are otherwise at least shorter than the time corresponding to the shortest mark space length. The level of Pc1 is so set as to attain the temperature at which the crystal growth rate of the recording layer is remarkable. The level of Pc2 is so set as to attain the temperature at which the crystal nucleus forming frequencies of the recording layer are remarkable.

Title: Component feeding tape
Inventor: OKADA TAKESHI
IPC: H05K13/02
Filed: 1990-10-29
Abstract: PURPOSE:To prevent generation of extra trash at a time of peeling off a top tape and to prevent the trash from entering an attracting nozzle by providing perforations or cuttings along a longitudinal direction of the top tape on both side edges of the tape. CONSTITUTION:A top tape 1 is provided with two perforations 7 on both outsides of parts sealing hole 3. A carrier tape 2 is, in this case, a paper tape. A bottom tape 9 covers a lower surface of the component sealing hole 3. A component feeding tape carries out peeling-off of the top tape 1 along the perforations 7, and therefore, the top tape 1 remains unpeeled off at an adhesive part 6. Thus fiber-like trash is not generated and possibility that the dust is attracted by an attracting nozzle is decreased. In addition, if a space between the both sewing traces 7, that is, a width of the top tape to be peeled off, is dimensioned larger than the width of the component sealing hole 3, taking-out of components becomes smooth.

Title: Optical disk system
Inventor: YAMAUCHI MINEO
IPC: G11B7/00
Filed: 1987-11-20
Abstract: PURPOSE:To improve a reliability even for a burst error by recording in double the same signal at the position where the phase is slided 180 deg. and located on a disk in case of writing a signal on an optical disk. CONSTITUTION:When the same signal is recorded by sliding the phase 180 deg. for the signal recording zone 2 of an optical disk, it is made to be recorded in double respectively in bisected zones 21, 22. On the other hand, in the optical disk, the probability of generating the origin of a burst like error simultaneously at the position apart 180 deg., e.g., at two points of A, B is extremely less. In case of reading a signal from one part of the zone 21 for instance the signal can be read from the other part of the zone 22 when an error is caused on this signal. The reliability can thus be remarkably improved.

Abstract: PURPOSE:To avoid the concentrated arrangement of the macro block center of blocks and also shorten the processing time of the development of the macro block by deciding the positions of the external terminals of the macroblock prior to the arrangement processing of the blocks within the macroblock. CONSTITUTION:Prior to arranging blocks 2-9 within a macroblock 1, the positions of the external terminals are decided considering the positions of other terminals 21-34 to be connected with the external terminals 11-15 of the macroblock 1 or i/o pads 41-47. For this reason, in the arrangement processing of the blocks 2-9 within the macroblock 1, the arrangement positions of the blocks 2-9 are decided based on the connectional relation between the terminals 21-34 of the already arranged block and the external terminals 11-15 and the arrangement positions of already arranged blocks and the external terminals 11-15. Hereby, it can effectively avoid the concentrated arrangement of the blocks 2-9 to the center of the macroblock 1, and easily decide the wiring courses to the external terminals 11-15 of the macroblock 1, and shorten the processing time of the development of the macroblock 1.

The acrylate and amine in this case makes Michael addition exothermic reaction; in addition, the epoxy resin and amine make reaction as well to form a high polymer, thus yielding a cured epoxy body. The curing progresses even at an ordinary temp. and is much speeded up when heated. Such acrylate modified epoxy resin improves the collapsing property of the molding sand by gasification after casting even in the case of low-temp. casting such as casting of aluminum. The efficiency of the casting operation is thus improved.
