Title: Plated conductive wire
Inventor: NAKATAKI CHUICHI
IPC: H01B5/02
Filed: 1991-09-11
Abstract: PURPOSE:To improve solder wettability and soldering performance by forming an extremely thin rust preventive layer on a tinned or semiconductor plated conductive wire. CONSTITUTION:By forming a rust preventive layer on a tinned or solder plated layer, wettability is improved even if tinning or solder plating is formed by means of a melting plating method. The action of the rust preventive layer is not performed as desired if the layer is not extremely thin. That is, it is desirable for the thickness of the rust preventive layer to be set to 0.001-1mum. It is also desirable for the rust preventive layer to be a rust preventive agent containing a Si element, particularly a heat hardening thing of a mixture of a thermosetting epoxy resin and a hydrolysis dehydrate condensation type siyilalkoxide. A plated conductive wire obtained like this is excellent in heat resistance and high temperature-high humidity resistance, and for instance the plated conductive wire is excellent in solder wettability and soldering performance even after being left in the atmosphere of high temperature and high humidity for a long time.

Title: Power supply circuit
Inventor: IKEDA HIROKUNI
IPC: H02J9/00
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To save the waiting power by forming a self-holding circuit which turns on a switch for bypassing a non-lock type switch when the non-lock switch is turned on, and by providing an off timer means which turns off when the predetermined time has passed after the switch is turned on. SOLUTION: Under the condition that a power supply plug 2 is inserted to a receptacle of ordinary power source, when a non-lock switch 1 is depressed, a power source transformer becomes conductive and thereby the control circuit power source is applied to a single chip micro-computer 9. Consequently, with an output of the single chip microcomputer 9, a transistor TR5 becomes conductive and a drive coil L5 also becomes conductive to close a contact of a power source relay switch 5. Thereafter, even if conductivity of non-lock switch 1 is canceled, this switch self-holds with conductivity of the power source relay switch 5. An output of the single chip microcomputer 9 stops when the preset time of timer from the timer setting signal circuit 11 has passed and the power source relay switch 5 becomes off to cut the supply of commercial power source.

Title: Container for chemically converting tab terminal for electrolytic capacitor
Inventor: ISHII SHOJIRO
IPC: H01G13/00
Filed: 1992-09-04
Abstract: PURPOSE:To discharge a cleaning liquid from the title container so as to shorten the drying time required for removing the cleaning liquid. CONSTITUTION:Numerous drain holes 5, 5,... having diameters smaller than the thicknesses of the lead wires 13 of tab terminals 14 are bored through the bottom 4 of a cylindrical container 2. Since the holes 5 are formed through the bottom of the container 2, a cleaning liquid can be quickly discharged from the container after cleaning and the drying time of the tab terminals 14 can be remarkably shortened, resulting in an improvement in the manufacturing efficiency of the tab terminals 14. On the other hand, since the diameters of the holes 5 are smaller than the thicknesses of the lead wires 13 of the terminals 14, the lead wires 13 do not pass through the holes 5 and the terminals 14 do not drop down from the container 2. In addition, since the bottom surface 4 of the container 4 becomes rough due to the holes 5, slipping of the front ends of the lead wires 13 can be prevented and the terminals 14 are maintained in standing states.

Title: Amplifier circuit with switch
Inventor: UCHIDA NORIAKI
IPC: H03F3/72
Filed: 1989-10-11
Abstract: PURPOSE:To obtain the mute mode without need of a transistor(TR) for the mute mode by setting a gain to an input signal individually and selecting the gain to each input signal to be '0' when any of each input voltage current conversion amplifier circuit is not selected. CONSTITUTION:The gain to each input signal is set variably for each by varying a transfer conductance of input voltage current conversion amplifier circuits GM1-GMn. When a switch circuit SW does not select any of the input voltage current conversion amplifier circuits GM1-GMn, the gain to each input signal is all zero and the mute mode is selected. In this case, a DC level at the output is equal to a reference voltage fed to a feedback voltage current conversion amplifier circuit GMNF and no voltage change is caused. Thus, the gain is set individually to each input signal with less number of components and the mute mode is obtained without need of a TR for the mute mode.
