Abstract: PURPOSE:To provide a manufacturing method for thermal heads which can be completed in a short operating time and also of high yield by simultaneously removing a conductor wiring layer between conductor wiring and on a thermal resistor and a resist, and allowing an etching to be done to a thermal resistor layer between wiring without contact of the etchant with a conductor wiring. CONSTITUTION:A thermal resistor layer 2 composed of Ta2N, Ta-Si, Ta-SiO2, etc. of 0.05-0.2mum is formed on the surface of a high resistance substrate 1 by evaporation or sputtering. Then a conductor layer consisting of Au, Al, etc. ranging from 0.5-2mum in thickness is formed. In addition, an unnecessary part of the conductor layer is etched using a regist pattern 4. Next, after removing the regist pattern 4, the unnecessary part of the thermal resistor layer is again etched using the regist pattern 5. Here, if the regist pattern 5 is removed, a thermal resistor is formed. Consequently, a conductor layer on the thermal resistor and a conductor layer between the conductor wiring are etched simultaneously, thus shortening an operating time.

Title: Output voltage stabilizing circuit
Inventor: TANAKA RYOZO
IPC: G05F1/56
Filed: 1989-03-28
Abstract: PURPOSE:To freely limit the output current by providing a current limiting circuit on the outside of a four-terminal regulator and controlling the base current of its output current supply transistor TR by the four-terminal regulator and not supplying the output current from the four-terminal regulator. CONSTITUTION:A base current IB of a TR 7 flows between the emitter E and the base B of the TR 7 through a regulator 10 and a resistance 14. As the result, hfa-fold current IB flows between the E and the collector C of the TR 7. The value of the current IB is so controlled by the four-terminal regulator that the output voltage is fixed; and for example, the four-terminal regulator 10 increases the input current to increase the base current IB when the output voltage is lower. When the voltage between both ends of a resistance 5 exceeds the value of VEBS of a TR 6, the current flowing between the E and the C of the TR 7 is limited. Thus, the current limit value is freely set.

Title: Digital phase locked loop circuit
Inventor: HASEGAWA ATSUSHI
IPC: H03L7/06
Filed: 1988-04-01
Abstract: PURPOSE:To shorten the transient response time during which a phase locked state is secured by giving the variable control to the dividing number of a dividing circuit every time the phase comparison result is obtained between an input signal and the output of the dividing circuit. CONSTITUTION:A phase comparison deciding circuit 4 transmits no signal at all within a phase comparison deciding period and a dividing circuit performs an m-dividing action. A dividing number control circuit 5 transmits the control signal for dividing number (m-1) to a dividing circuit 6 after a phase advance signal is received from the circuit 4. As a result, the dividing circuit output 2 has its rise earlier by an extent equal to one reference clock cycle. In case a phase asynchronizing signal is inputted to the circuit 4, the output of a phase comparator 3 is transmitted to the circuit 5 as it is. Thus it is not required to increase the working speed of a digital phase locked loop circuit and it is possible to shorten the transient response time to secure a phase locked state.

IPC: H02N2/00
Filed: 1982-05-11
Abstract: PURPOSE:To reduce power consumption with low revolution and low torque by utilizing the bending vibration of a piezoelectric bendable vibrator. CONSTITUTION:When an AC signal is applied to a vibrator 13, the vibrator 13 bends and vibrates. In this case, since the center G of the vibrator 13 is displaced to the position where is designated by a broken line, it is displaced from the holding point G' of a terminal 14. Since attracting force 22 is operated between the metal plate of the vibrator 13 and a permanent magnet 16, the vibrator 16 is pulled by the force 22 reversely to the force 21, but since the end of the terminal 14 is contacted at an acute angle phi, it is not returned reversely to the force 21, and the rotary force 23 is generated in this manner. In this case, the component force 212 of the force 21 is inverted in the period corresponding to the resonance frequency, but the force 21 always exists in the same direction, the rotary force 23 continues.
