Title: Power-supply control method
Inventor: INTO JUNICHI
IPC: H02M7/48
Filed: 1995-02-15
Abstract: PURPOSE: To obtain a power-supply control method in which a power supply can be controlled optimally even when a transformer to be used or a control method to be used is changed by a method wherein an increase or a decrease in the ON-width of a PWM signal in the feedback control operation and the forward control operation of a power-supply transformer is controlled differently. CONSTITUTION: A power-supply control circuit is initialized, and data on a register or the like is set ($10). Then, four access operations of a PWM signal are detected, and the number of detections is judged, by using a register update sequence (S12), while 1 is being added (S11). When it is judged that the four access operations have been continued, an interrupt register is cleared (S13), and U/D information is sampled so as to be saved in a flag register (S14). The information is compared with the last information (S15). When both are identical, an increase or a decrease in the pulse width of the PWM signal is controlled differently according to the U/D information. In addition, when the information differs from the last information, the number of interrupt operations of a U/D stop flag is set (S17, S18), and a procedure is returned to a start at the number of operations.

Title: Safety device of open type burner
Inventor: TAKAHASHI MUTSUHIKO
IPC: F23N5/24
Filed: 1987-03-05
Abstract: PURPOSE:To actuate fire-extinguishing means at the time of an oxygen deficiency and not to actuate the same at the time of normal fire extinguishment by providing a thermal deformation element in contact with or in the vicinity of a combustion cylinder, provided an interlocking member through an operating frame actuating an automatic aseismatic fire-extinguishing device so that the fire-extinguishing device responds to the thermal deformation element, and also providing an engaging part with respect to the interlocking member. CONSTITUTION:When oxygen becomes deficient in combustion air, a combustion reac tion in the vicinity of the tip end of a wick 1 becomes delayed. When the temperature of the reaction is lowered, the temperature in the vicinity of a combustion cylinder 6 also is lowered, this displaces a bimetal 5. By this displacing force, an inverted L-shaped interlocking member 8 is disconnected from an engaging part 13, an automatic aseismatic fire-extinguishing device operates and extinguishes fire. At the time of a normal fire-extinguishing operation, when an operating knob 17 is pushed up, the interlocking member 8 is pushed up normally by a fire-extinguishing lock lever 15 via the operating frame 9. Therefore, even when the temperature is lowered, the auto matic aseismatic fire-extinguishing device 7 at the time of oxygen deficiency is locked so that it cannot operate.

The crossectional area b μm<2> is set within the range of 5a<2> >b>a<2/2> in order to prevent wiring from being cut and also a sheet from being broken due to the concentration of a stress. The injection-moldings with grooves having a width (a) and a crossectional area (b) are manufactured using a thermoplastic polymer alloy composed mainly of a styrene resin such as polystyrene or a non-crystalline thermoplastic resin or a non-crystalline resin such as polyarylate, or some crystalline thermoplastic resin whose crystalline is low.  Thus it is possible to enhance the printability and suppress the generation of defects in the outward appearance.
