Title: Manufacture of lead acid battery
Inventor: TOKUNAGA AKIO
IPC: H01M4/22
Filed: 1987-01-29
Abstract: PURPOSE:To increase the cycle performance of a lead-acid battery by pouring low specific gravity sulfuric acid containing stannous ion in a non-charged battery using a lead-calcium based alloy grid, conducting in-container formation, and replacing the low specific gravity sulfuric acid with high specific gravity sulfuric acid containing stannous ion, then adjusting the specific gravity of the electrolyte in a specified value. CONSTITUTION:A specified amount of sulfuric acid, into which SnSO4 (stannous sulfate) is added as the supplier of Sn<2+>, having a specific gravity of 1.05 is poured (the primary electrolyte-pouring) in a non-charged lead-acid battery using a cast grid made of a Pb-Ca-Sn alloy. The in-container formation is conducted at a current of 200% of the theoretical capacity of a positive electrode for 20 hours. After completion of the formation, the electrolyte in the battery is removed, and high specific gravity sulfuric acid added with SnSO4 so as to have the same concentration of Sn<2+> as the primary electrolyte-pouring is poured (the secondary electrolyte-pouring), and the specific gravity of the electrolyte is adjusted to 1.28. The initial performance and cycle performance of the lead-acid battery are increased.

Title: Plate making method lithographic plate
Inventor: SUZUKI AKIHIKO
IPC: G03F7/40
Filed: 1981-02-11
Abstract: PURPOSE:To provide a fine printing matter without the generation of ground soiling by burning in a lithographic plate under the presence of borofluoric acid salt. CONSTITUTION:In a burning method for a material for lithographic plate after it is subjected to image exposure and development, the lithographic plate is made by burning in the material under the presence of a borofluoric acid salt or by treating the material with a solution containing borofluoride after burning-in. When using this treatment for the counter-etching pretreatment, for example, even if a plate held as it is after burning-in is used for printing, a fine printing matter is obtained without any ground soiling. Even though said pretreatment is incompletely performed so as to leave a portion not having coated with said salt, the counter-etching effect still extends to this portion from the circumference to prevent the ground soiling. Further, execution of the counter- ethcing aftertreatment can remedy the ground soiling generated from lack of the counter-etching treatment.

IPC: B01D21/02
Filed: 1980-02-19
Abstract: PURPOSE: To eanble easy refining of muddy water in the site where it is produced, by treating the muddy water produced at a construction work site with a full automatic muddy water sedimentation separator using a portable tank provided with a filter.  
     CONSTITUTION: Muddy water is fed to a preliminary settling chamber through water supply pipe 6, and foreign solids are removed with filter 7 in muddy water receiving chamber 5. Suspended solids higher in specific gravity settle on inclined separating plates 4 during the time when the muddy water passes above plates 4, and the sediment is discharged with a conveyor. Then the muddy water overflows into duct 11, enters the bottom of main settling chamber 13, and flows upward between sedimentation separating bodies 30, 30'. During this time, suspended grains settle and deposit on the bottom plate, and turbidity of the water gradually descends. The water is filtered with the filter of water permeable pipes 36, and flows into pipes 36 as a supernatant water. This water, when it rises to the position of level controlling plates 38, 38', enters filtrate water chamber 14, and then, it is drained through drain pipe 15.

IPC: C23C14/16
Filed: 1979-02-22
Abstract: PURPOSE:To form the distinct patterns free from undulations by applying the 1st surface treatment on a metal blank, printing the desired patterns with the specific resist ink and applying the 2nd surface treatment then dissolving away the printed layer. CONSTITUTION:A dissimilar metal covering layer 4 is formed on a metal blank material 3 such as of brass whose surface has been polished by a method such as electroplating or vapor deposition and desired patterns 5 are screen-printed on the surface thereof by using insulation-type resist ink. Thence, a copper plating layer 6 is deposited on the portions other than the patterns by electroplating, after which the blank material is dipped in a sulfide solution, then copper sulfide is formed and the copper plating layer colors. Hence, if the resist printed layer 5 is dissolved away by a thinner or the like, the undercoating layer 4 of the color differing from the color of the copper plating layer appears in correspondence to the pattern, whereby the distinct and smooth patterns 2 as if they are printed are formed. Finally, protecting transparent coating 7 is applied.

Title: Semiconductor displacement convertor
Inventor: SHIMAZOE MICHITAKA
IPC: G01L1/18
Filed: 1980-02-22
Abstract: PURPOSE:To insulate completely between a strain detecting body and a cantilever and solidify the union of both, by bonding a semiconductor strain detecting body wherein a strain detecting body is formed in a polycrystal dielectrically isolated to an alloyed material with an intervention of metallic intermediaries. CONSTITUTION:A strain detecting body is formed by a semiconductor substrate 11, N type polycrystalline region 13 having P type strain sensing resistance 12, an SiO2 film 14 and a multicrystalline region 15. On the reverse surface of the substrate 11 metallic multilayers are formed as a metallic intermediary layer 18, and this intermediary layer 18 and a cantilever 20 are bonded by eutectic alloy 19. In a displacement converter with such an arrangement, because the resistance 12 is electrically isolated from the cantilever 20 by the film 14, when the alloy 19 is attached to the substrate 11 on melting the electrical insulation does not deteriorate. And because the formation is so made that the alloy layer as bonding agent does not intrude into the region 15 owing to the presence of the intermediary layer 18, the bonded part is not damaged even if a great amount of displacement is given to the cantilever 20.
