Abstract: PURPOSE:To make it possible to use a RAM incorporated with a refresh circuit by means of a normal CPU by forming a chip selecting signal for selecting the RAM by the combination of a select signal, a refresh signal and an address strobing signal. CONSTITUTION:The address strobing signal outputted from the terminal ASTB of the CPU 1 is inputted to an R/S flip flop (FF) 7 through an inverter 6 and the refresh signal outputted from a terminal REFRQ is directly inputted to the FF 7. Negative logic-logic product between the output of the FF 7 and the address strobing signal is found out by a gate 8. On the other hand, negative logic-logic products between the output of the gate 8 and select signals outputted from output terminals Y1, Y2 are respectively found out by gates 9, 10. The outputs of respective gates 9, 10 are inputted to the terminals CE of respective RAMs 3, 4. Consequently, the RAM incorporated with the refresh circuit can be used without using an exclusive CPU.

Title: Liquid fuel combustion device
Inventor: UNO KATSUHIKO
IPC: F23D3/10
Filed: 1984-03-06
Abstract: PURPOSE:To suppress the formation of large upstanding flame, which might otherwise be formed in sharply changing the combustion state of fuel from less intense to intense modes and realize a stable combustion even when allowed to stand as it is after ignited, by providing a solid range at an area adjacent to a wick of at least one of inner and outer flame cylinders, excepting for the air ports group of lowermost step, and a large hole range immediately above the solid range. CONSTITUTION:A solid range 16 is provided upwardly adjacent to a wick, excepting for the air holes groups 8a of lowermost step, and a large hole range 17 larger in diameter than other sections is provided immediately above the solid range 16. The presence of solid range 16 eliminates the formation of upstanding flame (f) at an area adjacent to the top end of wick 14, and thereby maintaining low an ambient temperature around this area. A black-colored heat resistant metal oxide paint is coated from the lower end to the upper end of solid range 16 to prevent a heat radiation and red heat, while simultaneously increasing a thermal capacity for thereby maintaining low a temperature around the wick 14. Thus, no large unstanding flame is formed above a combustion cylinder or extended outwardly beyond an outer case. Moreover, a stable flame (f) can be formed at an enlarged range 17 even when allowed to stand as it is after ignited.

IPC: G06F17/16
Filed: 1985-03-05
Abstract: PURPOSE:To improve the access efficiency of a memory device by providing plural address holding means for addresses to receive accesses and selecting one of the addresses held by said holding means to execute an access to a bank. CONSTITUTION:When an address register 6-2 stores no effective access address, an address of an address saving register 10-3 is supplied unconditionally to an address register 6-3 via a selector 11-3. If the register 6-2 stores an effective access address, the access due to the effective address is compared with the access due to the address of the register 10-3 in terms of priority. If it is decided that the priority of the address of the register 10-3 is higher than that of the effective address of the register 6-2, an address is supplied to the register 6-3 from the register 10-3. While an address is supplied to the register 6-3 when the priority of the address of the register 6-2 is higher than that of the address of the register 10-3. Thus the contents of the register 10-3 are held with no change.

While a forward voltage is applied to a main thyristor as a igniting command optical signal, a continuous optical pulse is supplied to a photo transistor(TR) PTR and when igniting is failed, the current in the circuit flows to a gate of the main thyristor SCR via a diode D2, the TR1 and a resistor R3 and the igniting energy is supplied in succession. Thus, the ignition is established without fail in the timing satisfying the specified current required for igniting the main thyristor SCR.
