Title: Hot water temperature thermostat circuit of hot water boiler
Inventor: MURAKAMI SHIGERU
IPC: G05D23/24
Filed: 1982-10-06
Abstract: PURPOSE:To solve the problems of delay in the temperature of a detecting element in the initial period of combustion and of the lowering of the temperature of hot water in the combustion stabilizing period by detecting the temperature gradient due to the load condition and setting the setting level to two stages, ''low'' and ''high'', depending upon the condition of the temperature gradient. CONSTITUTION:The setting level is selected to two stages. The setting level is made variable by the output of an AND circuit formed by the outputs of a timer circuit and a hot water temperature thermostat circuit. When a power source 1 is opened, the output of a comparator 7 becomes ''1'', and a signal is supplied to a combustion control circuit 8 and the boiler assumes a combustion condition. Simultaneously, charge of a capacitor 12 is started through a resistor 11. Under this condition, the output of the AND circuit 14 is zero because the input at its one side is zero. For this reason, a transistor 18 is turned OFF, and the setting level assumes a condition determined by series resistances of resistors 3 and 9, that is, a ''low'' set condition. When charging to a capacitor 12 advances under this condition, and the setting level reaches a predetermined level, a signal of ''1'' is supplied to the AND circuit 14 through a resistor 13. In a case where combustion continues at this time point, that is, the output of the comparator 7 assumes a value ''1'', the output of the AND circuit 14 assumes a value ''1'', and the transistor 18 is turned ''ON'', and the resistor 9 is put into a short-circuiting state and the setting level is put into a ''high'' set condition.

Title: Concrete structure and crushing method thereof
Inventor: TAKAARA HIDEO
IPC: C22C19/03
Filed: 1993-06-22
Abstract: PURPOSE:To eliminate the need for making a bore hole while minimizing labor and the time required for a pretreatment process by breaking a concrete structure, in which aggregate using a shape memory alloy is incorporated, by heating action. CONSTITUTION:A bar made of a shape memory alloy is buried previously in concrete as aggregate for reinforcement, and a wall, a floor, a ceiling, etc., are formed and constructed beforehand. When these wall and others must be repaired and removed afterwards, the bar of the shape memory alloy in concrete is heated. The form of the bar of the shape memory alloy is changed simultaneously into a previously stored linear shape (b) from a corrugated shape (a). Concrete is crushed by utilizing the change of the form. Since the bar is fast stuck to concrete, deformation force can be applied completely to concrete without loss, thus effectively breaking concrete in that degree.

Title: Nickel zinc battery
Inventor: IWAI KATSUJI
IPC: H01M10/30
Filed: 1982-10-06
Abstract: PURPOSE:To obtain a nickel zinc battery in which any internal short circuits which might be caused, between the positive and the negative plates, due to zinc dendrite developing on the zinc plate during charging by performing nickel plating on the inner area of a sack-like separator on which the periphery of the plate is located. CONSTITUTION:After not less than two pieces of sack-like separators are stacked to form a separator 7, a zinc plate 3 or a nickel plate is inserted into the separator 7. Next, nickel plates 1 and 1' or zinc plates are placed outside the separator 7 before electrolytes 8 and 8' are charged, thereby constituting a nickel zinc electrode. For example, the separator 7 is formed by inserting a zinc electrode 3 in a sack-like separator 7', followed by inserting it in a sack-like separator 7'' before it is inserted in a sack-like separator 7''. Nickel plating 9 is performed on the area of the separator 7'' on which the periphery of the plate 3 is located. Owing to such constitution as above, zinc dendrite on contacting the nickel plating 9 after penetrating the separators 7' and 7'' is converted into zinc oxide while producing hydrogen before being dissolved into the electrolyte. As a result, any internal short circuits can be prevented and the life of the battery is increased.
