Title: Capacitor
Inventor: ABE SAKAE
IPC: H01G2/06
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To allow solder to surely flow through from a solder surface, by forming a protruding part between lead wires in such a manner that solder may flow through from the through-hole seat on a mounting surface, and retaining a body by the bottom surface of the protruding part. SOLUTION: A protrusion 1 is formed between lead wires 5, and a body is retained by the bottom surface of the protrusion 1. After a capacitor element 3 is molded by using epoxy resin 4, a protrusion constituting part wherein the height A of the protrusion 1 is about 2mm is formed. Lead wires 5 are fixed to the capacitor element 3, and the whole part is molded by using incombustible epoxy resin. The size of the protrusion constituting part 2 is determined by the size of the capacitor. Thereby the root of the lead wire is prevented from coming into contact with a printed board or permeating into the board, so that solder surely flows through from a solder surface.

Title: Current waveform transmitter
Inventor: TAKASHIMA TOSHIHIRO
IPC: G01R15/20
Filed: 1988-02-22
Abstract: PURPOSE:To easily and certainly detect the waveform of an electric current flowing to a conductor by providing a current detecting means utilizing a Hall effect and a means which sends the output of the detecting means after converting the output into optical signals. CONSTITUTION:A Hall element 10 is driven by a fixed current IC and leads out voltage signals corresponding to the magnetic field B induced by the current flowing through a conductor impressed from the outside. When the magnetic flux density B induced by the current I flowing through the conductor is impressed upon the Hall element 10 provided in the vicinity of the conductor when the element 10 is driven, the element 10 outputs a Hall voltage VH and gives the voltage to an amplifier 11. Therefore, the waveform information of the current flowing through the conductor is converted into the waveform information of voltages by the Hall element 10. The waveform information of voltages is converted into frequency information corresponding to the waveform of the current flowing through the conductor by means of a V/F converter 12 and the pulse signal is sent to an optical fiber 14 after the signal is converted into optical pulse signals. The optical pulse signals supplied to the optical fiber 14 are sent to a transmission section provided on another place.

Abstract: PURPOSE:To produce a resin adsorbing a pure extractant by cleaning an organic phosphorus compound extractant with an alkaline aqueous solution containing alcohol, separating the two phases and removing the water phase, admixing an adsorbing resin, stirring the three phase system of resin, extractant and aqueous solution to produce a two phase system of solid phase and water phase, removing the water phase and then cleaning and drying. CONSTITUTION:A planed quantity of organic compound extractant is preparatively isolated and cleaned with an alkaline aqueous solution containing alcohol and then it is separated into two phases and the water phase is discarded. It is then admixed with an adsorbing resin and the three phase of adsorbing resin, extractant and alkaline aqueous solution 15 stirred for about three hours. Consequently, the oiliness disappears and a two phase system of solid phase and water phase is obtained. The water phase is discarded and the solid phase is cleaned with an alcoholic aqueous solution before being dries at about 110 deg.C. Consequently, an acid organic phosphorus compound can be removed in the form of soap-like hydrophilic salt using an alkaline aqueous solution where the solubility to the water phase is enhanced by means of alcohol.

Title: Printing device with print check function
Inventor: IZAWA MITSUTOSHI
IPC: B41J7/34
Filed: 1984-03-01
Abstract: PURPOSE:To arrange so that the print may be automatically checked by providing the first head for printing serial-type dot characters and the second head for reading these printed characters optically and collating the printed characters with the read-in results. CONSTITUTION:Character codes and other data sent from a host unit are stored into a line buffer 2 by an interface control part 1 and then are read by an editing part 4 to extract a corresponding dot pattern from a character generator 3. Then the dot is printed by a pin head hammer 6 through a print line carriage control part 5. A scanner 7 fixed in the backward of a hammer 6 proceeding direction detects a print pattern which is converted to a logic signal by a scanner control part 8 and is recognized as a character by a recognition part. After these procedures, a comparison part 10 pre-reads a character pattern to be detected in advance from a character generator 3 through the line buffer 2 and the editing part 4 and collates the character pattern with a character recognized by the recognition part. The following printing action is continued only when collated results coincide with each other.

Title: Overcurrent limiter
Inventor: YAMAMOTO MASANORI
IPC: H01F36/00
Filed: 1990-02-22
Abstract: PURPOSE:To return a superconductor to a superconducting state by a stable operation, by reducing a voltage impressed forcedly on the superconductor after the superconductor of a current-limiter is quenched by an overcurrent exceeding the critical current value thereof and makes transition to a state of normal conductivity. CONSTITUTION:Although return to a superconductive state after a superconductor 2 is quenched is difficult if it is left as it is, a semiconductor switch 4 monitors a voltage between the opposite ends (a) and (b), and conducts a control for closure at a voltage value being equal to or lower than the one appearing when, after an overcurrent once flows and the voltage appears between the (a) and (b), the overcurrent is suppressed and returns to a normal current value, while conducting a control for opening when the voltage is zero. In this way, a superconducting transformer 6 can be operated without causing quench for a faulty overcurrent, and since the superconductor 2 is returned to a superconducting state by the operation of the semiconductor switch 2 immediately after the cause of a fault is eliminated and since a current limiter is then separated from an electric system, the superconducting transformer 6 can be operated without any hindrance.

Title: Preparation of ethoxysulfate with improved (reduced) bad odor
Inventor: SEKIGUCHI SHIZUO
IPC: C07C301/00
Filed: 1980-03-28
Abstract: PURPOSE: To obtain the titled compound useful for imparting an aroma to a detergent product with improved (reduced) bad odor, by sulfating an ethoxylate adjusted to a moisture content of specific wt% with gaseous sulfur trioxide diluted with an inert gas, and neutralizing the sulfation product.  
     CONSTITUTION: An ethoxylate of the formula RO-(C 2 H 4 O) n -H (R is 8W20C  straight or branched chain alkyl; n is 1W20) is sulfated with gaseous sulfur trioxide diluted with an inert gas, and the sulfation product is then neutralized to give the titled compound. In the process, the moisture content of the ethoxylate is previously adjusted to a range of 0.3W3wt%, preferably 0.5W2wt%, and sulfated. The moisture content both above and below the range has no preventing effect on smelling and reduces the sulfation ratio undesirably. In spite of the sulfur trioxide easily damaged by water used, the presence of the water rather improves (reduces) the smelling of the sulfation product in the reaction.
