IPC: G06F13/36
Filed: 1990-03-02
Abstract: PURPOSE:To improve the data transfer efficiency by storing the distinction between the extending specifications or the non-extending specifications of each board into the memory of each board and transferring the data immediately from the memory while confirming the specifications of the board of the opposite side at the second transfer of data. CONSTITUTION:The extending specifications are decided in a read cycle set to a board B 22 from a board A 21, and M(n) = [1, 1] is written into a memory, When the same cycle is carried out once again, the board A 21 of the extending specifications asserts a signal *EXP together with an address in the first half of a bus cycle. Then the board A 21 stops the drive of the signal *EXP after asserting an address strobe signal *AS to secure a high impedance state. Then it is possible to confirm the extending specifications of the board B 22 of the opposite side via the memory by reference to M(n) = [1, 1]. Then the transmission of an address is immediately discontinued before the board B 22 asserts the signal *EXP, and the transfer of data is started in the latter half. Thus the data transfer efficiency is improved.

Title: Control device of hot water supply
Inventor: NUNOKAWA HIROYUKI
IPC: F24H1/00
Filed: 1981-04-07
Abstract: PURPOSE:To save power by a method wherein the upper part of water in a hot water tank is  kept at a high temperature in a midnight power supply time zone so as to meet an unexpected  need for hot water irrespective of the quantity of hot water used on the previous day and the  temperature of the hot water is selectively determined in response to the variation of the temperature of the city water. CONSTITUTION:When the temperature of the city water is high, switches 33 and 33' are turned  on (a) whereupon a relay 30 is not energized but a relay 32 is energized through high and low  temperature thermostats 27 and 28 with the result that a contact 321 is closed to energize only  a main heater 2 provided in the lower part of the hot water tank. Further, when the switches  33 and 33' are turned on (b), the relay 31 closes a contact 311 so that only an auxiliary heater  3 provided in the upper part of the hot water tank is energized. Thus, when the upper part of  the water in the hot water tank is heated to a high temperature, an upper thermostat 25 is  opened, the contact 301 is turned on B side and the relay 32 closes a contact 321 to thereby  energize the main heater only. On the other hand, when the temperature of the city water is  low, the switches 33 and 33' are turned on (c) to perform the same manner of heating as when  they are turned on (b) but in this case, the supply of power to the main heater 2 is controlled  by the high temperature thermostat 27 as a result of the low temperature thermostat 28 being  shortcircuited.
