Abstract: PROBLEM TO BE SOLVED: To enhance the image density while eliminating an adverse effect of blurring image by emitting an auxiliary light during an interval for printing one line in addition to emitting light from a light emitting diode for an image data at the time of printing of a black character pixel. SOLUTION: Since a strobe signal STR1 outputted from a printer control section 20 is inputted to an AND gate 71, the data of each pixel latched at the first part 931 of a latch circuit 93 is inputted to each LED element constituting the first part 81 of a light emitting diode LED print head 80. Since a next strobe signal STR2 outputted from the printer control section 20 is inputted to an AND gate 72, the data of each pixel latched at the second part 92 of the latch circuit 93 is inputted to each LED element constituting the second part 82 of an LED print head 82.

Filed: 1995-04-11
Abstract: PURPOSE: To carry out a solar battery paddle control signal from the earth normally, even though an error operation is generated to a control logic circuit by a disturbance noise and the like, in a solar battery paddle driving control device of an artificial satellite. CONSTITUTION: The output signal of a command processing circuit 1 depending on the control signal from the earth, and a control mode decided by a control logic circuit 2, are monitored by a command monitor circuit 7 and a control mode monitor circuit 8 respectively, and they are compared in a condition monitor control circuit 9.

Abstract: PURPOSE:To recover efficiently Ga having high purity at a high yield in the stage of recovering Ga by electrolysis from an aq. mineral acid soln. contg. Ga by separating preliminarily the excess acid from said aq. soln. by using an ion exchange membrane. CONSTITUTION:Waste contg. Ga and an Na aluminate soln. by a Bayer's process are pretreated to an aq. soln. mineral acid soln. contg. Ga in the stage of recovering Ga from said soln. Said aq. mineral acid soln. contg. Ga and water are passed through a diffusion dialysis cell in which the aq. mineral acid soln. is passed through one side and the water through the other side in counter current via an ion exchange membrane, thereby separating the excess acid. The pH of the resultant dialyzate is adjusted to the range in which Ga can be isolated by electrolysis and thereafter the liquid is electrolyzed to obtain G. A small amt. of the alkali to be added in the electrolysis is thus required and therefore the trouble with the electrolysis arising from the coexistence of a large amt. of salt is averted. The increase in the amt. of the aq. soln. to be treated is obviated as well.

Title: Gas shut off device
Inventor: FUJIEDA HIROSHI
IPC: F17C13/04
Filed: 1982-06-25
Abstract: PURPOSE:To decrease consumption of a battery as small as possible, by manually resetting a solenoid valve after its shut off through sensing of abnormality with a gas flow sensor and supplying power source voltage to a resetting detector circuit after output of a cutoff signal to the solenoid valve. CONSTITUTION:A resetting detector circuit 4 is constituted by a field effect transistor (FET)4A and a resistor 4B. The FET4A provides zero voltage between gate sources and a turn on state between drain sources. If a solenoid valve 3 is operated to be manually reset, an electromotive force is generated in a coil, and this causes a reverse bias between the gate sources of the FET4A, if it exceeds a cutoff voltage, the FET4A is turned off. A microcomputer 2B generates an output O1 in a level Hi before output of a cutoff signal and an output O2 in a level Lo, no supplying power source to the resetting detector circuit 4, in this way, consumption of a battery in this circuit 4 is almost zero.
