IPC: G06F1/08
Filed: 1990-10-12
Abstract: PURPOSE:To realize a normal timer operation by frequency-dividing the basic clock of a prescribed frequency and generating a clock signal supplied to a unit. CONSTITUTION:A generator 10 generates the basic clock whose frequency is always constant. When power voltage changes and it changes from regular voltage to low voltage with certain slice voltage (voltage which is previously set) as a boundary, it is detected in a voltage detector 14 and high and low level signals are generated. A switching circuit 16 changes over the signal to either of two kinds of clock signals in a frequency-dividing circuit 12. At the time of regular voltage, the clock signal of the high frequency is outputted, and the clock signal of the low frequency is outputted at the time of low voltage. Thus, the switching of the clock frequency smoothly follows in accordance with the switching of voltage and the clock can be generated at the stable prescribed frequency even if power voltage and a peripheral temperature fluctuate.

Title: Rotary bearing
Inventor: KITAMURA YOSHITAKA
IPC: H01J35/10
Filed: 1986-11-19
Abstract: PURPOSE:To minimize wear by setting up a plurality of turning members which move relatively to each other via respective rolling members to reduce the relative speed of each of the turning members with respect to each of the rolling members. CONSTITUTION:A turning bearing 10 is a multiple-structure in which a plurality of annular turning members 11-15 making relative movement and differing in diameter are concentrically piled up with respect to the turning center C via rolling members 16-19. Turning a turning positive pole 2 generates a moment to turn the turning members 11-15 successively via the rolling members 16-19. However, the turning moment is suppressed by the rolling members 16-19 gradually so that a turning member piled more apart from the turning shaft 2 turns at slower speed. The relative speeds between each of the turning members and each of the rolling members contacting them are minimized so that the turning bearing 10 itself is subjected to extremely low wear.
