Title: Sealed lead-acid battery
Inventor: NOBEYAMA KOICHI
IPC: H01M2/18
Filed: 1989-03-31
Abstract: PURPOSE:To properly absorb oxygen gas with an anode plate at the time of charging by providing a separator having acid resistance and water repellent quality and forming a plurality of separated spaces between anode active material layer and a cathode active material layers. CONSTITUTION:The predetermined form of a separator 7 having acid resistance and water repellent quality is positioned between a cathode active material layer 5 and an anode active material layer 6. The aforesaid separator 7 is in contact with both active material layers 5 and 6, thereby forming a plurality of separated spaces 9a to 9d between the layers 5 and 6. In addition, electrolytic liquid retainers 8a to 8d are held in the spaces 9a to 9d. Consequently. the separator 7 is not impregnated with an electrolytic liquid and the surfaces of the active material layers 5 and 6 in contact with the separator 7 are free from the electrolytic liquid. Also, the separator 7 and the electrolytic liquid retainers 8 are different from one another in quality and the separator 7 has water repellent quality. A passage for oxygen gas, therefore, is formed among the separator 7 and the retainers 8. According to the aforesaid construction, oxygen gas is properly absorbed.

Title: Optical recording medium
Inventor: YAMAMOTO NOBUO
IPC: G11B7/24073
Filed: 1988-04-04
Abstract: PURPOSE:To enable sure tracking as well as recording and reproduction by forming pregrooves and prebits so as to have surface rugged structures. CONSTITUTION:The regular surface-rugged structures having the repetitive length smaller than the wavelength of laser beams are imparted into the pregrooves. The reflected light rays of the light projected to the pregrooves, therefore, diffract and interfere with each other and are thereby decreased in the intensity thereof; further, the light rays interfere with the reflected light on the outside of the pregrooves, by which the intensity thereof is additionally decreased. The effective and sure information on tracking is thereby obtd. This method is particularly effective when the surfaces of the pregrooves and the regions excluding the same are coated with the films which are the same, i.e., the same in reflectivity, for example, recording films.
