Title: Protecting circuit for power converter circuit
Inventor: KAWABATA OSAMU
IPC: H02M7/48
Filed: 1985-11-25
Abstract: PURPOSE:To effectively prevent secondary accidents due to a DC shortcircuit such as burnout of a current limiting resistor at AC power source ON time by detecting the shortcircuit on the basis of a voltage and a current of a DC circuit and tripping a power source breaker. CONSTITUTION:When a power source breaker 2 is closed even in a state capable of forming a DC shortcircuit due to the damage of transistors of positive and negative arm pair of transistors 8a-8f, a current flows through the arm where DC-shortcircuit of an inverter 8 is encountered but does not flow to a capacitor 5. Accordingly, a voltage detection signal 10a is at non voltage level, and a current detection signal 11a exceeds an overvoltage level. A protecting circuit 20 outputs a shortcircuit detection signal, and trips the breaker 2.

Abstract: PURPOSE:To improve fixability and offset resistance by constituting the compsn. of at least a binder resin and a dye pigment and blending a small ratio of polyphenylene oxide which is a high melting material with a styrene resin as the binder resin. CONSTITUTION:This compsn. consists of at least the binder resin and the dye pigment and the binder resin consists of 99 to 80pts.wt. styrene resin and 1 to 20pts.wt. polyphenylene oxide which is the high melting material. The ratio at which the styrene resin occupies in the toner binder resin is 99 to 80pts.wt., more preferably 97 to 85pts.wt. The offset resistance as a toner is deteriorated if the ratio excess 99pts.wt. The low-temp. toner fixability is poor if the ratio is below 80pts.wt.

Filed: 1986-11-12
Abstract: PURPOSE:To improve the efficiency of using bits by providing plural slave devices with means which decide the agreement or disagreement of a NAME and inhibit slave equipments except for the one specified by the NAME added to 1st data. CONSTITUTION:When a host equipment 1 transmits a strobe signal (to show the existence of a series of data) and the 1st data through a bus 5, the slave equipments 2, 3 and 4 compare the NAME in the 1st data with NAMEs set through their NAME switches 9 at the timing of the rise of the strobe signal with the aid of comparators 6. Since the NAME of the 1st data shows the slave equipment 2, the comparators 6 for the slave equipments 3 and 4 detect the disagreement of their NAMEs, and output a guard signal 8 that inhibits inputting data in their data input buffers 7. The guard signal 8 continues until the strobe signal disappears. Thus the 1st data is fetched only by the slave equipment 2.
