Title: Speedometer
Inventor: IWATA KAZUTOSHI
IPC: H02P29/00
Filed: 1984-05-18
Abstract: PURPOSE:To detect effectively speed even at a super-low speed, by measuring number Cn of pulses of a high-frequency clock until detection of the No.2<n> pulse of a shaft encoder and searching for K/C (K: proportional constant determined number of clocks at the full speed and number of pulses) basing upon this number Cn of pulses. CONSTITUTION:A shaft encoder 1 generates a pulse signal EAB of a plurality of phase A, B. This signal EAB is supplied to a judging circuit 13 of rotating direction of pulse sending a pulse signal E synchronized corresponding to a plural multiplication (for example 4 times) of a detecting pulse basing upon the clock pulse C. This signal E is counted by the No.2<n> pulse detecting counter circuit 14 and only No.2<i> (i=0, 1...n) pulse is selected and detected. Further, number Cn of pulses of the clock until detection of the No.2<n> pulse of the encoder 1 is measured by a circuit consisting of clock-counter circuit 3, latch circuit 8, etc.. K/C is detected 10, basing upon this number of pulses Cn, by a instruction of a microprocessor circuit 2 and the speed is detected by shifting it in the lefthand direction by an exponent number n.

Abstract: PROBLEM TO BE SOLVED: To provide the red and blue dyed stoner that is narrow in a particle diameter distribution, improved in light resistance and sublimability, and enhanced in density by incorporating a specified colorant in the red dyed toner. SOLUTION: The red dyed toner is prepared by dyeing powdery grains composed essentially of a thermoplastic resin with the colorant represented by the formula in which R1 is an H atom or an alkyl or phenyl or methylphenyl group; and R2 is an H atom or an alkyl ester group. The thermoplastic resin grains are embodied by polymer grains obtained by pulverization, suspension polymerization or emulsion polymerization. The resin narrow in grain diameter distribution is obtained, preferably, by using seed polymerization or the dispersion polymerization in which a monomer and a polymerization initiator and a polymer dispersant are dissolved in an organic solvent at the same time and polymerization is initiated by keeping the reactants at a constant temperature.

Title: Piezoelectric transformer
Inventor: KIKUCHI HIROMI
IPC: H01L41/107
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized, high-efficiency piezoelectric transformer having a high boosting ratio specifying the ratio of the resonance resistance of a generating part to the resonance resistance of a driving part. SOLUTION: A piezoelectric transformer has construction provided with input electrodes 3, 4 for applying voltage to a lead zirconate titanate family piezoelectric ceramic 1 for example, and an output electrode 5 for taking power out. The input electrodes 3, 4 are formed in a driving part where vibration by an inverse piezoelectric effect of the piezoelectric ceramic 1 is excited, and the output electrode is formed in the generating part where vibration is taken out as power by a normal piezoelectric effect. In the piezoelectric transformer, the ratio Rg/Rd of the resonance resistance Rg of the generating part to the resonance frequency Rd of the driving part is determined to be 30 or less.  If the ratio exceeds 30, the efficiency lowers and becomes lower than 80%, and a calorific value on the occasion of driving the piezoelectric transformer increases, and operation of an inverter for liquid crystal back light becomes unstable. Accordingly, a piezoelectric transformer small-sized, capable of producing large output power, and high-efficiency is obtained, if the ratio Rg/Rd<30 is satisfied.
