Title: Thermal fuse
Inventor: TACHIBANA KANICHI
IPC: H01H37/76
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a thermal fuse low in internal resistance and reliable in function. SOLUTION: A press spring 6, a temperature-sensitive fusible element 4, a movable contact 3, an elastic contact 2, an opening spring 5, a sealing body 7 with lead wires 8, 9, are in order inserted into a metallic sleeve 1. The temperature-sensitive fuse element 4 abuts on the movable contact 3. The elastic contact 2 and the movable contact 3 are each provided with a through hole in their middle for inserting therein an end of the lead wire 8. This construction allows a press spring 6 stronger than before to be used, and therefore contact resistance is lowered between the temperature-sensitive fuse element and the movable contact, abutting on each other, and thus internal temperature rise can be suppressed.

Title: Digital signal multiplexer
Inventor: MORI SHOKICHI
IPC: H04J3/16
Filed: 1986-06-18
Abstract: PURPOSE:To simultaneously execute the multiplexing and series conversion by controlling a parallel/serial converter giving a serial output to a transmission line by allocated information of a data signal length. CONSTITUTION:A value of a data signal bit length being bit allocation information is given to a down-counter 4 from a memory 1, decremented by one in synchronism with a master clock signal. A circuit 5 detecting a value below 1 gives a signal to the memory 1, the parallel/serial converter 3 and the down- counter 4 when the content of the down-counter 4 reaches 1 or below and loads a next new data signal to the parallel/serial converter 3 and the down-counter 4 from the memory 1. The data signal given and loaded in the parallel/serial converter 3 is sent as a serial signal in synchronism with the master clock signal and becomes a multiplexed output signal. Thus, the signals having a different data signal length are converted one after another, subjected to serial multiplexing, then the result is sent so as to apply the serial conversion and multiplexing of the data signal simultaneously.

Title: Thermal printing head
Inventor: NOMOTO TSUTOMU
IPC: B41J2/35
Filed: 1977-11-30
Abstract: PURPOSE: To make possible minimizing the change in heating resistance and the effect of the variations thereof on the applied power of heating elements by series connecting additional resistors having resistance values more than 0.15 times the resistance values of heating resistors to said resistors.  
     CONSTITUTION: As pulses are supplied between selected conductors, e.g., 121 and 122, 125 and 126, heating resistors 101, 103 evolve heat to obtain picture elements. At this time, additional resistors 111 thru 118 which do not contribute to color formation are inserted and connected respectively to the heating resistors 101 thru 104 via conductors 121 thru 128. When the individual resistors are attached to a group of heating resistors, the relations of the change rates of the heating resistor values and the change rates of the applied power of the heating elements are indicated by n=(additional resistor resistance value)/(heating element resistance value). The figure reveals that additional resistance corresponding to n≥0.15 is required to keep the variations of the applied power within ±10%, thus by providing the additional resistors and suitably setting the value of n, the problems of uneven densities, deterioration acceleration, etc. may be solved.

Abstract: PURPOSE:To control and to keep the temp. distribution in a soaking furnace at desired optimum state, by adjusting the quantity of atomization, a medium for atomizing fuel, in accordance with the deviation of the detected temp. difference between the temps. at the burner side and at the opposite side from the predetermined temp. difference. CONSTITUTION:At first, temp. difference is set to an indicating controller 26, then a temp. difference arithmetic unit 25, having received detected signals from temp. detectors 8a, 8b arranged on burner side and the opposite side, calculates temp. difference and makes a signal in accordance with the temp. difference. The controller 26 compares the signal with the set value, and the temp. of the side opposite to the burner is adjusted to make the temp. difference approach to and coincide with the set value. For that purpose, the conroller 26 makes a signal for opening or closing an atomize contrl valve 28 in accordance with the interrelation between the atomized quantity and the temp. difference in the furnace. As a result, temp. difference is kept at a desired optimum by the change of fuel flow rate even when the furnace temp. distribution in the furnace is changed remarkably.

Filed: 1991-06-14
Abstract: PURPOSE:To enable the Young's modulus, true stress and coefficient of thermal expansion of a film whose such mechanical characteristics are unknown to be measured up to film- formation temperature by forming and laminating films of known and unknown mechanical characteristics each other on a base, and finding the mechanical characteristics of the films from their deformation due to pressure and temperature, and dividing each of values obtained. CONSTITUTION:A material test piece 21 comprises a film 22 of known mechanical characteristics, i.e., Young's modulus, true stress and coefficient of thermal expansion formed on an Si base 5; a film 23 of unknown mechanical characteristics is laminated thereover; and a window opened through the base 5 by etching. The test piece 21 is set in a pressure regulator 3 and stored in a heating furnace 2 and heated to film-formation temperature while atmospheric gas 8 is allowed to flow therethrough. Amounts by which the films 22,23 are deformed when made to swell or shrivel by pressure buildup or pressure reduction by pressurizing gas 9 are measured by a laser microscope 1. The heating enables Young's modulus, true stress and coefficients of thermal expansion from room temperature to the film-formation temperature to be found at one sample. Because the measured values are those of the combination of the films 22, 23 the values are each divided to find values of the film 23 of unknown characteristics.

Title: Fixation of anticorrosive layer at junction
Inventor: YAMAGUCHI MASAYUKI
IPC: H02G15/08
Filed: 1977-11-29
Abstract: PURPOSE: To prevent the projection of anticorrosive layer from the end of body tube due to contraction by the procedure in which axial notches are cut into the anticorrosive layer of junction, the cut portion is bent outwards, and spacer is put in its inside and fixed so that the diameter is larger than the inside diameter of the body tube end portion at junction.  
     CONSTITUTION: Notches are axially cut into the end portion of the anticorrosive layer 6 in the end of the body tube 5 at junction, and the cut portion is bent outwards by dividing it into plural numbers. And, the spacer 8 is inserted into the inside of the bent piece 11, and the outer periphery of the bent piece 11 with the spacer is intergrally fixed with the string 9. Thus, the outside diameter of the bent piece 11 is formed so as to be larger than the inside diameter of the end portion of body tube at junction. Accordingly, even if the anticorrosive layer 6 of cable is contracted, the contraction is prevented and the passage of water from the water- proof tape layer 7 into the inside of cable can be thus prevented because the diameter of the bent piece 11 is larger than the inside diameter of the end portion of the body tube 5 at junction.
