Title: Method and device for preventing fire in laser beam machine
Inventor: ENDO KOICHI
IPC: B23K26/12
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To prevent a fire from being caused by spatters, etc., generating at the time of laser machining of a work on a brush table. SOLUTION: In this device, a work W placed on a brush table 19 of which lots of bristles 17 are planted on the surface, is machined by being irradiated with a laser beam from a nozzle at the lower end of a laser machining head 11. The brush table 19 in the vicinity surrounding the laser machining head 11 is covered with a machining head cover 29, and a metal-made fire preventive table 41 is installed on the brush table 19 in the area of a range covered by the head cover 29, so that the work is laser-machined on the fire protective table 41.  Since the work is covered with the machining head cover 29 in the range of the fire protective table 41, even if spatters generating in the laser- machining scatter in the surrounding, a fire does nor generate because the lower face is the fire protective table 41 and also, since the scattering spatters in the surrounding are shielded by the machining head cover 29, the brush table 19 is prevented from a fire.

Title: Memory chip
Inventor: SOGA MITSURU
IPC: G11C11/401
Filed: 1994-11-21
Abstract: PURPOSE: To provide a memory chip performing memory access at a high speed when the same data are written in continuous addresses. CONSTITUTION: A length register 7 stores the number (span length) of memory cells in which the same data are written. A color register 8 receives the written data from the outside to store them. A span mask generation part 5 generates mask information specifying a part in which the data are stored from the span length and a column address starting span development. A column decoder 4 writes the data in a sense amplifier 3 according to the mask information. Thus, since only a plot start address and the span length may be inputted to the memory chip, the data are written for plural memory cells at once access, and the memory access is accelerated.

Title: Magnetic resistance element and magnetic bar code detector
Inventor: WAKAUMI HIROO
IPC: G06K7/08
Filed: 1990-10-25
Abstract: PURPOSE:To attain highly sensitive reading by forming plural magnetic resistance films on an IC substrate with about 45 deg. inclination angle from the side face of the substrate and serially cascade-connecting respective films. CONSTITUTION:Respective magnetic resistance films 22 are formed on the IC substrate 20 in parallel in the vertical direction with about 45 deg. inclination from the scribe face (side face) 20a of the substrate 20 and serially cascade- connected through respective conductive films 22a. Thereby, the lateral width (length in the side face direction) of the film 22 for detecting a magnetic field change is reduced to 1/sq. rt. 2 the length in its longitudinal direction. Thereby, even when an engraved bar code groove 30 on an iron plate 40 is a high density pattern, the film 22 is not spanned across both opposed sides of the groove 30 and the pattern can be read out. Consequently, a high density bar code pattern can be read out with high sensitivity.

Title: Particulate filter
Inventor: HAYASHI KOTARO
IPC: F01N3/02
Filed: 1990-10-29
Abstract: PURPOSE:To ensure ignition and propagation of combustion of particulates in a circumferential area of a filter by increasing the density of plug members, which prevent exhaust gas from entering the filter, in a central area of the filter, and decreasing the density of the plug members in the circumferential area of the filter. CONSTITUTION:Plug members 7 are arranged so that the ratio of area of the plug members 7 to a unit area of a filter viewed from the upstream side of exhaust gas, that is, the density of the plug members, is larger in a central area 1c of the filter inside the broken line circle than in a circumferential area 1d surrounding the central area of the filter higher. As a result, the density of exhaust gas inlet passages 5 included in the central area 1c of the filter whose exhaust gas upstream ends are open is smaller than the density of exhaust gas inlet passages included in the circumferential area 1d. This makes the seizure of particulates larger in the circumferential area of the filter than in the central area of the filter, thus ensuring the ignition of particulates in the circumferential area of the filter.
