Title: Power circuit for electronic clock
Inventor: HANAOKA TADASHI
IPC: G04G3/00
Filed: 1979-06-08
Abstract: PURPOSE: To supply a signal from an oscillation circuit to a voltage dividing circuit through which power is supplied to a clock circuit and thus to economize power by connecting power of the oscillation circuit transiently to a power battery when closing the power battery.  
     CONSTITUTION: From inserting a battery 8, a battery voltage is impressed on an oscillation circuit 1 and a frequency dividing circuit 2 through a starting condenser 9. Upon starting of oscillation, a time reference signal is subjected to frequency division 2 and transferred to a voltage dividing circuit 7 through a level shift circuit 3. The voltage dividing circuit 7 thus begins to operate, divides the battery voltage and supplies power to the oscillation circuit 1 and the frequency dividing circuit 2. After that, the condenser 9 operates as that of removing ripples of an output voltage of the voltage dividing circuit 7.

A conducting layer 6 is inevitably formed by the high temperature annealing of the layer 2. A desired resist pattern is formed. With the pattern as a mask, an isolating opening part 8 is formed by etching. After photoresist 7b is removed, an SiO2 applying liquid is applied on the entire surface by spinning and a film is formed. At this time, the isolating opening part 8 is completely buried by the SiO2 applied film 9. Thereafter, the SiO2 applied film 9, which is formed on the main surface of the substrate 1 other than the isolating opening part 8 is removed. Thus, the conducting layer, which is formed by the high temperature annealing of the semi-insulating GaAs substrate, is divided, and the element isolating effect can be enhanced.

The glass substrate 1 is then dipped in chloroform solution of 4 % trimethyl chlorosilane for 24 hours so that the surface of the glass substrate is subjected to hydrophobic treatment. The substrate is then rinsed well with chloroform solution. Dried nitrogen gas freed of dust or other contaminant is blown upon the glass substrate 1 to dry the same. Subsequently, gold is resistance heated by means of a vacuum deposition apparatus and a gold electrode pattern is formed by using a vapor deposition mask. Thereby, it is possible to orient hydrophobic portion of amphipathic molecules towards the gold electrode and to accumulate one over another directly.

Abstract: PROBLEM TO BE SOLVED: To reduce wave noise sharply, and improve durability by arranging a zinc rich layer on the surface layer of a brass made rotor electrode. SOLUTION: A zinc rich layer 1a having zinc content of 40 to 60wt% is arranged on the surface of a brass made rotor electrode 1. In the case where the zinc content is 40wt% and less, there is no effect for suppressing intermittent discharge.

One side of the longitudinal direction of the rotor electrode 1 is formed as a discharging part 2, a strong dielectric material layer 3 is formed on the surface of the discharging part 2 so as to form a coating rotor electrode 5. The coating rotor electrode 5 is installed and used on the rotor of a plurality of distributors, and thereby, it is possible to reduce discharging voltage, and also suppress intermittent discharge.
