Filed: 1985-09-19
Abstract: PURPOSE:To prevent short circuit between positive and negative plates by forming the end of a mat-type separator, to be in contact with the cut end of a negative plate using expanded grid, in low moisture content structure, and suppressing the expansion of active material in the cut part. CONSTITUTION:A sealed lead-acid battery is formed with a negative plate using expanded grid and a mat-type separator.

Abstract: PURPOSE:To obtain a blanket improved in the affinity to printing ink and the releasability of said ink by molding the blanket using silicone rubber as a molding stock and covering the effective surface thereof with a porous membrane composed of a metal or metal oxide. CONSTITUTION:A blanket 4 is molded using silicone rubber as a molding stock and the effective surface thereof subjected to the transfer of printing ink is covered with a porous membrane 5.

Title: Manufacture of semiconductor laser
Inventor: OTA HIROYUKI
IPC: H01S5/00
Filed: 1993-08-23
Abstract: PURPOSE:To reduce the end-face level of a laser bar so as to increase the output of the laser by depositing a dielectric protective film on the end face of a laser bar by dipping the laser bar in a specific solution together with a positive and negative electrode plates and making an electric current flow between the electrode plates. CONSTITUTION:A negative electrode plate 3 on which a laser bar 1 is fixed and a positive electrode plate 4 are dipped in (NH4)2S or (NH4)2Sx (ammonium polysulfide) solution and a 5-mA electric current is immediately made to flow between the electrode plates 3 and 4 for five minutes. When the electric current is made to flow, the COD level of the solution rises and an optical output of 60mW in maximum can be obtained. Therefore, the output of the laser bar can be increased, because an optical output which is four times as large as that obtained under an unprocessed state can be obtained. The reason why such a high output can be obtained is that the COD level of the solution is improved, because the etching of the end face of the laser bar by (NH4) ions is suppressed and the average surface concentration of sulfur adhering to the end face is increased.

Filed: 1986-09-03
Abstract: PURPOSE:To obtain a detector which is reliable and usable in a high humidity atmosphere while reducing its size and improving the mechanical strength by measuring the error rate of a dynamic random access memory(DRAM) due to alpha rays and detecting the alpha rays. CONSTITUTION:This detecting device consists of the DRAM1 uses as a detection part for radiation, a data writing part 2, a data reading and matching part 3, and a count display part 4. Then known write data is written in the DRAM1 by the writing part 2 and the matching part 3 matches read data with the write data before the writing to the DRAM1 a specific time later. If the written data has an error owing to the passage of alpha rays, the result of the comparison between the read data and write data indicates dissidence, so the matching part 3 outputs an error signal. The count display part 4 counts error signals and displays the counted value. The counted value increases in proportion to the intensity of the alpha rays, so the intensity of the alpha rays is detected from the counted value.
