Title: Terminal connecting device
Inventor: MATSUBARA GENYO
IPC: H01R13/71
Filed: 1990-03-08
Abstract: PURPOSE:To carry out electric contact of a terminal to contact pads securely by preventing that the terminal scrapes a solder cream layer when it is inserted for connection. CONSTITUTION:Projections 16a and 17a are formed on the opposite surfaces of respective engaging members 16 and 17 which are projected further from the top end of a terminal, 15 on the end surface of a main body 11. And by inserting the end 21 of an insulating plate-formed member 20 between the terminals 15 of a connector 10, the front end of the plate-formed member 20 abuts to the projections 16a and 17a, depressed by the larger projection 17a, and contact pads 22 on the upper surface are separated from the terminal 15. As a result, a solder cream layer is never scraped, and when the plate-formed member 20 is inserted in a gap 18 sufficiently, the projections 16a and 17a are fitted in apertures 23, and the terminal 15 touches the contact pads 22 and the solder cream layer on the surface. Consequently, secure soldering can be applied between the terminal 15 and the contact pads 22.

Title: Switched capacitor filter
Inventor: ADACHI TOSHIO
IPC: H03H19/00
Filed: 1989-03-09
Abstract: PURPOSE:To quicken the processing speed of the filter by supplying an input signal to an inverting input terminal of an operational amplifier via a switch switched with a 1st phase clock signal and connecting a prescribed added input capacitive element to the inverting input terminal via a switch switched with a noninverting clock signal. CONSTITUTION:The difference from a conventional circuit resides in that capacitors CX and CY are added via a switch closed synchronously with a clock signal phi1. That is, the input capacitance is C1+-C2 when the clock signal phi1 is set and a clock signal phi2 is reset when a 1st operational amplifier circuit Amp 1 is noticed, and the input capacitance is CX when the state of the clock signals is opposite to above. When the relation of CX=C1+C2 is set, the feedback quantity is always the same, a sufficient phase margin is obtained thereby expanding the processing enable band. When the 2nd operational amplifier circuit Amp 2 is noticed and when the clock signal phi1 is set and the clock signal phi2 is reset, the input capacitance is expressed as C3+C4+C''1 and when the state of the clock signals is opposite to above, the input capacitance is expressed as CY+C''1. Thus, with the selection of CY=C3+C4, the quantity of feedback is kept always constant.

Abstract: PURPOSE:To reduce the power consumption of a stepping motor and to prevent the stepping motor from making noise caused by an overcurrent so as to keep quiet environment by using the stepping motor as an original carrying means and adjusting a current impressed on the stepping motor in accordance with necessary torque. CONSTITUTION:The stepping motor M3 is used as the original carrying means and the current impressed on the stepping motor M3 is adjusted in accordance with the necessary torque. Namely, a resist roller 90 and a carrying belt 95 are driven by a single main motor M3 without making a clutch intervene, and the main motor M3 is pulsatively driven as the stepping motor. By controlling the number of pulses supplied to the motor M3, the original fed from the resist roller 90 is accurately carried/stopped at a reference position. It may be good that the motor M3 is on/off controlled by attaching an encoder to a rotary shaft and converting revolving speed to the number of pulses.

Abstract: PROBLEM TO BE SOLVED: To connect a pipe securely through the entire circumference of it by providing a joint main body in which a circulating groove is formed and which is provided with a connecting hole at the bottom of its circulating groove and a joint cover which covers the circulating groove and to which the joint main body is connected. SOLUTION: In a joint main body 10, a circulating groove 11 is formed in a metal block of rectangular parallelopiped, cube, or cylinder, and a connecting hole 13 is formed in the bottom 12 of the circulating groove 11. Also a pipe 2 is inserted into the connecting hole 13, and the bottom 12 of the circulating groove 11 is welded to the end of the pipe 2. Next a joint cover 14 prepared separately is welded to the joint main body 10 so as to close the circulating groove 11. When the pipe 2 and joint main body 10 are made of gun metal or copper, they may be connected by silver soldering instead of welding. In a pipe joint device of such a constitution, because the joint main body 10 can be connected to the pipe 2 from the circulating groove 11 side, the connection is not obstructed by the adjacent joint main body or pipe.

Abstract: PURPOSE:To the deterioration of a discharge characteristic due to spot welding or gas generation from a film layer by integrally forming a discharge part and feeding piece of an electrode from single metal raw material, and forming an oxidation film layer on only the sealing part surface of the feeding piece. CONSTITUTION:Groove holes are punched in parallel and intermittently on both sides of a belt-like metallic plate to form the sealing part 52 of electrode raw material 53. Degasification-treatment is made in a hydrogen-reduced atmosphere, then a corresponding position between the discharge part 91 and a feeding piece 92 of the metallic plate is airtightly nipped with a die, only the sealing part 52 is exposed to be retained in a furnace in a wet hydrogen atmosphere, and an oxidation film layer 93 is formed on only the surface of this part.
