Patent JP-H10145142-A (JP)
Title: Quartz oscillator circuit for solar clock
Inventor: NAKANO KATSUMASA
IPC: H03B5/32
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To realize stable oscillation by using plural regulator circuits and controlling regulation potential on a load circuit at the time of starting the oscillation. SOLUTION: An oscillation stop circuit CONT1 is started, and the presence or absence of transmission is judged with the supply of power. When it is absent, a power potential detection circuit CONT2 is started, and the detection level of present power potential is compared with that of setting power potential. When potential is low, which is high in a positive direction, power potential is supplied to a quartz oscillator circuit by the first regulator circuit containing the second regulator circuit 109. When potential is high, which is high in a negative direction, regulation potential generated in the circuit 109 is supplied through the first regulator circuit.  Thus, the oscillation starting ability of the oscillation circuit does not deteriorate when the regulation potential of the circuit 109 is generated, so that supply potential when power potential higher than a setting power potential detection level becomes the same value as power potential supplied when potential is low.

Filed: 1993-11-10
Abstract: PURPOSE:To improve water resistance and corrosion resistance by constituting a bearing member of a ceramic bearing part having a bearing hole and a ceramic shaft to be inserted in the bearing hole. CONSTITUTION:When a ceramic shaft A2 is inserted in a bearing hole 1 of a ceramic bearing part A1 and rotated, gas or liquid in a clearance K forms a rotating vortex in the circumference of a protruded part 4 along the fine irregularity 4, 5 on the bearing hole 1 and on the surface of the ceramic shaft A2.
