Abstract: PURPOSE:To obtain electromotive force in response to the rotating speed of a rotary member by connecting a plurality of electrodes so that the electromotive forces generated by the curving of a bimorphic plate caused by the rotation of the rotary member are added to each other. CONSTITUTION:In a bimorphic plate 1, monomorphic plates 1a and 1b forming a pair are stuck together so as to hold a common terminal plate 2 comprising a thin metal plate. The monomorphic plates 1a and 1b comprise piezoelectric ceramics. When the plate is curved in the thickness direction, electromotive force is generated across one-surface side and the other surface side. The polling directions of the monomorphic plates 1a and 1b are made to be the directions of arrows A and B and arrows C and D. A plurality of electrodes 3 and 4 and electrodes 5 and 6 are formed on the surface parts of the monomorphic plates 1a and 1b. The electrodes 3 - 6 are connected so that the electromotive forces which are generated by the curving of the bimorphic plate 1 caused by the rotation of a rotating member 7a are added to each other. Thus, the electromotive force in response to the rotating speed of the rotary member is obtained.

Title: Digital pll circuit
Inventor: SHIMIZUME KAZUTOSHI
IPC: G11B20/10
Filed: 1987-05-22
Abstract: PURPOSE:To improve the stability by supplying an output signal of a digital low pass filter via a nonlinear conversion circuit provided with a blind sector for a signal near a prescribed value. CONSTITUTION:The input/output characteristic of a nonlinear conversion circuit 14 is set such that the output is '0' with respect to the input in the range of, e.g. -l-+1. When an input data having a high frequency fluctuation due to peak shift is fed to an input terminal IN, an output of a phase comparator circuit 11 exceeding + or -1 is fed to a digital low pass filter 12. Then an output + or -1 appears at the output of the digital low pass filter 12 depending on its arithmetic error at this point of time. Since the nonlinear conversion circuit 14 has a blind sector of + or -1 as stated above, the output is '0'. Thus, the arithmetic error of the digital low pass filter 12 is absorbed and eliminated by the nonlinear conversion circuit 14, useless fluctuation of a digital PLL circuit 10A is prevented and the stability is improved.

Abstract: PURPOSE:To prevent the overheating and the damage of reformer system equipments, by introducing a gas contaminating a reformer catalyst to the upstream of a high temperature shift converter, when a temperature rise to show a methane reaction in the system including a reformer and the high temperature shift converter is detected. CONSTITUTION:When a thermometer detects a temperature rise to show a methane reaction, breaker valves 12, 14 and 15 are opened, a nitrogen flow control valve 17 and a hydrogen sulfide flow control valve 18 are controlled to make the density of the hydrogen sulfide at several % by weakening with nitrogen, and the gas is introduced to the upper stream of a high temperature shift converter 9.

Filed: 1988-05-23
Abstract: PURPOSE:To make the size of the circuit small and the weight light by controlling a bias voltage applied to a diode in a microwave band power amplifier so as to act a distortion generating circuit as a linear circuit. CONSTITUTION:A capacitor 17 is used for DC cut-off and a resistor 18 is used to divide a bias voltage at a bias terminal. A positive voltage is applied from a bias terminal 14 to a diode 11 in a nonlinear compensation circuit to apply a bias so as to give a current flowing in the forward direction.
