Title: Brazing structure
Inventor: SENBA KATSUAKI
IPC: B23K1/14
Filed: 1984-01-18
Abstract: PURPOSE:To pass substantially solder between members and to perform adequate brazing by forming a supporting part in the notched part provided to a lower member and disposing a wire brazing material in the upper part of a notch by the supporting part. CONSTITUTION:An included base 21 is formed in the notch formed to a copper member 19 and a wire brazing material 18 is disposed in the high position of a notch 20 in the stage of brazing an insulating end plate 16 and the copper member 19, etc. which are tentatively assembled. The material 18 is then held in place between the metallized layer 17 on the bottom surface of the plate 16 and the base 21. If brazing is accomplished by such structure, the molten solder sticks to the corner part where the plate 16 and the member 19 intersect and is thus sucked into the space between the two. Stagnation of the solder in the lower part of the notch 20 and generation of an unfilled part and thus decreased. Such brazing structure is adequately usable for a vacuum interruptor.

Title: Image forming device
Inventor: OZAWA ICHIRO
IPC: G03G15/08
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To make smaller an error of the control of toner concentration, caused by electrified carried mixed into developer due to the repetition of an image forming operation. SOLUTION: A command is preset in a CPU so that the initial reference-value 2.5 V of an inductance quantitative detection sensor is reset to a new reference- value 2.75 V, when an image forming operation has been repeated 25,000 times. The CPU resets it to a detection signal reference-value 2.75 V outputted from a reference-voltage signal power source when the number of times of the repeated operation reaches 25,000. Thus, toner replenishment is stopped until the detection signal reaches 2.75 V, then an error of toner concentration which has been caused so far is eliminated, and control is re-exerted to obtain an initial toner concentration of 6%.

Title: Transister logical circuit

IPC: H03K19/018
Filed: 1980-01-25
Abstract: PURPOSE:To reduce not only the number of component parts but the power consumption, by using a TTL input circuit and a level converting circuit in common. CONSTITUTION:In case the potential of the input terminal in1 is the maximum level VOL(max) of the ''L'' output potential of the TTL element the 1st state, the base potential VBB of the 1st transistor T5 is decided by the forward potential of the diodes D67 and D8 each. In this instant, the transistor T5 conducts, and the emitter current IS1 flows. Accordingly the voltage of Vout1 VCC-Vbe(T6)- IS1R5 emerges at the output terminal out1. On the other hand, the potential of the terminal in1 is the minimum level VOH(min) of the ''H'' output potential of the TTL element (the 2nd state), the base potential of the T5 is equal to the case of the 1st state. Thus the potential is identical between the T5 and the terminal in1, and accordingly the T5 becomes nonconductive. As a result, the voltage of Vout1 VCC- Vbe(T6) emerges at the terminal out1.
