Title: Hot water feed device with hot water bath-feeding function
Inventor: KURIKI KEIICHI
IPC: F24D17/00
Filed: 1989-03-08
Abstract: PURPOSE:To allow a quantity of hot water flowing out from a hot water opening not to lower during hot water feeding from a plug even if the hot water is allowed to flow out to accumulate in a bath by providing a hot water bath-feeding waiting means for waiting hot water bath-feeding until a hot water feed detection means detects the stop of the hot water feeding in the case where a hot water bath-feeding instruction means receives an instruction for performing the hot water bath-feeding during a period at which the hot water detection means is detecting hot water feed. CONSTITUTION:When a hot water bath-feeding instruction means is switched on in a condition to feed hot water, the indication of hot water bath-feeding is displayed in a display means of a controller 24. In this case, when a quantity of the hot water detected by a water flow sensor 53 is in a condition to exceed a specified quantity of water (2-3l) (during hot water feeding), a close valve is in a condition to switch off. When a plug is closed or the opening of the plug is lessened and the hot water does not reach the specified water quantity (2-3l) (hot water feeding stop), the waiting condition of the hot water bath-feeding is released. In other word, since the hot water feeding is stopped to perform the hot water bath-feeding even if the instruction of hot water bath-feeding start is performed, the quantity of the hot water allowed to flow out from the plug is not lowered.

Title: Manufacture of manganese dioxide for nonaqueous cell
Inventor: NANKAI SHIROU
IPC: H01M4/50
Filed: 1978-05-11
Abstract: PURPOSE:To manufacture the title MnO2 with high efficiency discharge characteristics, high positive electrode utilization rate and superior shelf stability by heat treating electrolytic MnO2 followed by acid treatment. CONSTITUTION:MnO2 obtd. by electrolysis is finely pulverized and heat treated at 300-450 deg.C to remove water contained. As the heat treatment temp. is raised, cell discharge performance deterioration is reduced in storage. This tendency is esp. remarkable in case of high temp. storage. The higher heat treatment temp., however, lowers high efficiency discharge characteristics and remarkably increases cell internal resistance in storage. The heat treated MnO2 is treated with hydrochloric acid, hydrofluoric acid, bromic acid or the like to dissolution remove Mn2O3 formed on MnO2 particle surfaces by the heat treatment. The acid-treated MnO2 is then filtered, well washed with water to remove the acid, and dried. The resulting MnO2 is employed as the positive electrode active material of a cell using light metal such as Li as the negative electrode active material and a nonaqueous electrolyte.

Title: Air-heating furnace
Inventor: KISHIMOTO SUMIYUKI
IPC: C21B9/00
Filed: 1978-05-15
Abstract: PURPOSE: To prevent the change of Guiter brick due to creep at high temperature by enriching oxygen in combustion air and also by regulating the length of flame according to the combustion chamber capacity of external combustion type air- heating furnace and also the distance to the upper surface of regenerator's Guiter brick.  
     CONSTITUTION: In an external combustion type air-heating furnace using ceramic burners, a high temperature creep-caused change in the high-alumina Guiter brick 4 is often caused by the arrival and combustion of unburned gas to the Guiter brick 3 and 4 of the regenerator 2. Since the safe working limit temperature of the Guiter brick is approx. 1550°C, in case where the calorific value of gas is 1200 kcal/Nm 3 , oxygen content of combustion air is enriched to 24.5% to enhance the thermal efficiency by effectively burning gas. Also, when flame reaches the upper surface of the Guiter brick 3, the oxygen content of combustion air is enriched to more than 23% and the length of the flame is shortened to prevent the deterioration of Guiter brick, especially the high-alumina brick 4.

Title: Formation of film on plastic
Inventor: KUHARA TAKASHI
IPC: B32B15/08
Filed: 1983-03-31
Abstract: PURPOSE:To make it possible to form a metal compound film of good film properties and good adhesion, by forming the lowermost and uppermost layers of a film from an electroconductive material and a metal compound, respectively, and effecting the sputtering treatment by application of a negative voltage to the plastic. CONSTITUTION:In forming a film on a plastic (e.g., polycarbonate or polyacrylate) by sputtering, the formation of said film is carried out in such a manner that the film to be formed consists of a double-layer comprising an elctroconductive material (e.g., Cr, Ni, or Ti) and a metal compound (e.g., TiO2, Al2O3, or SiC); at least the lowermost layer of the film is formed from the electroconductive material and at least the uppermost layer of the film is formed from the metal compound, and sputtering is carried out by application of a negative voltage to the plastic. This process makes it possible to form a metal compound film of good film properties, which is difficult to produce by a conventional sputtering process. It is thus possible to widen its application field so as to meet a variety of requirements such as abrasion resistance and decorative performance.

SOLUTION: Water flow out of a water tank 2 is cut off, the level of the water tank 2 is abruptly raised up to a level HWL1 close to the maximum level from a reference level WL, and concurrently, at the time when a valve element 5 is abruptly lowered from a fully opened position to a fully closed position, let the flange 11A of a grudually closing device 11 abut against the upper end of a spring 11B so as to restrain a float 6 from being abruptly raised up, and also restrain the valve element 5 from being abruptly lowered down. Even if the level of water is gradually raised up from the level HWL1 close to the maximum level up to the maximum level HWL, and the valve element 5 can thereby be gradually lowered down while being restrained by a time difference by the energization of the spring 11B, so that the valve is thereby gradually closed.
