Title: Method for trimming resistor of thermal head
Inventor: NAKATANI KAZUO
IPC: H01C17/22
Filed: 1986-11-05
Abstract: PURPOSE:To shorten the time required in trimming and to keep the life of a resistor constant and long, by applying pulse voltages, which are respectively applied to resistor elements, to elements adjacent to each other in a time-shifted state. CONSTITUTION:Pulse generating circuits 10, 11 output pulses at times shifted by the half T/2 of a constant pulse cycle T and, therefore, pulse voltages due to the pulse generating circuits 10, 11 are applied to a plurality of resistor elements 9 at every one element. By this mechanism, when a certain resistor element is in a heating section (that is, during the application of a pulse), the adjacent element is in a cooling section and, therefore, heat is diffused to adjacent elements to hold said elements to uniform temp. as a whole. By this method, the time reaching a desired value by the pulse application of the same voltage becomes almost equal in all of elements without being restricted by an end part and the time up to the completion of trimming becomes rapid markedly. Since there is no difference of the rising in temp. due to the position of the resistor element, no irregularity is generated in the life of each element.

Filed: 1993-10-21
Abstract: PURPOSE:To efficiently separate particles from water by setting a frequency of high frequency voltage impressed between electrodes to equal or more frequency on which the polarity turns more rapidly than the reaction of nascent oxygen generated by applying current with colloid particles. CONSTITUTION:A liquid to be treated such as a waste solution is charged into a vessel 1, a specific high frequency voltage is impressed between the electrodes 5 and 6 with the starting of a power unit 2 to start a flocculating and separating treatment.

Title: Corrugated horn
Inventor: MIYATA YOSHIHIDE
IPC: H01Q13/02
Filed: 1984-12-14
Abstract: PURPOSE:To suppress a resonance phenomenon by securing a smooth continuous surface at a flare part at the feed side. CONSTITUTION:A flare part 21 which connects the main body 1 of an oval or rectangular opening corrugated horn and a feed waveguide 13 has a smooth and continuous surface. Here the length (l) of the flare 21 is set properly in the axial direction to obtain a 90 deg. relative phase difference between long and short axes of the opening of the corrugated horn. Then a circular polarized wave is obtained by setting the exciting direction of an electric field at + or -45 deg.. In such a way, resonance phenomenon is suppressed. Thus the coincidence is obtained between the H surface radiation pattern of an HE11 even mode (excitation with short axis direction field) and the E surface radiation pattern of an HE11 odd mode (excitation with long axis direction field). This improves the radiation characteristics of a corrugated horn.

Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce a power supply voltage required for amplifying a reproducing signal by arranging a constant current circuit parallelly with the load circuit of an amplifier element and supplying one part of DC current for driving of amplifier element from the constant current circuit. SOLUTION: A constant current circuit 38 is arranged parallelly with a collector resistor 35, and one part of DC current ID for driving of parallelly connected amplifier elements Q1 -Qn is supplied from the constant current circuit 38 to a totem pole type transistor 34. Thus, the value of DC current flowing to the collector resistor 35 can be reduced and the difference of DC potential between both the terminals of collector resistor 35 can be reduced just for it. Therefore, a positive side power source +Vcc and a negative side power source -Vcc can be turned into low voltage. Besides, since a current component to change a current value while following up the signal level of reproducing signal RF flows to the collector resistor 35 only, the drop of AC gain is effectively avoided and the degradation of C/N can be effectively avoided.
