Title: Silver peroxide battery
Inventor: TAKAHASHI TADAO
IPC: H01M4/06
Filed: 1982-07-09
Abstract: PURPOSE:To prevent any two-stage electric potentials and increase the capacity of a silver peroxide battery by means of thin silver-oxide layers by attaching a positive mixture inside a silver-plated metallic ring, and coating parts of the positive mixture which don't touch the metallic ring with said thin silver oxide layer to make a positive body. CONSTITUTION:After a positive mixture 7 is attached inside a silver-oxide metallic ring 9, parts (a) and (b) which don't touch the ring 9 are thermally treated for a short time so as to form siler-oxide surface layers containing 3-15wt% of silver oxide, thereby making a positive body.

Title: Printer
Inventor: URATA YOSHITO
IPC: B41J2/28
Filed: 1981-07-30
Abstract: PURPOSE:To achieve a high speed printing along with a reduced size and a saved power by striking a member to be struck with a common striking means while selectively retained according to printing signals in an impact type printer. CONSTITUTION:While a retaining means 5 is not excited, due to the advance of a common striking means 6 which reciprocates at a specified cycle, a member 11 to be struck moves forward by a charging force of a spring 13 following it until a wire 12 impacts an ink ribbon 4 but not a recording paper 2 as the charging force of the spring 13 is smaller than the tension of a ribbon 4. Then, upon excitation thereof, the striking means 6 is returned with the striken member 11. Then, according to printing signals, the retaining means 5 is selectively excited to attract an armature 10. Under such a condition, as the striking means 6 reciprocates in the printing direction, the striken member 11 is given a large energy enough to fly and perform a printing. Thus, the printing with the common striking means enables high speed operation with a smaller size. Energy consumpton is limited in the selection means for the printing because it is needed only for retaining it.

Filed: 1979-09-18
Abstract: PURPOSE:To prevent the clogging of a filter so as to improve the operation efficiency of electroless plating process, by controlling the temp. of plating soln. at the filtering stage. CONSTITUTION:In circulation and filtration of electroless plating soln., the filter is clogged because of the progression of the electroeess plating reaction on the filter. Hence passage of the plating soln., having been cooled before filtration, through the filter allows to prevent the clogging due to the deposition of metal on the filter. For example, in the circulation and filtration of electroless copper plating soln., the bath is cooled by 15 deg.C from 70 deg.C to 55 deg.C. Hereby, use of the plating soln. for a week or more causes no clogging compared with about two days of conventional methods.
