Filed: 1992-12-11
Abstract: PURPOSE: To measure oscillation of a gyro pendulum in a short time without damping the oscillation by detecting the deviation angle of the gyro pendulum or the like through an optoelectronic measuring unit and calculating the oscillation through a central processor. CONSTITUTION: The gyro 16 of a gyro pendulum 15 locked through a lock ring 23 or the like is fed with power until a desired r.p.m. is reached.

Title: Serial clock output circuit
Inventor: NISHINO MAKOTO
IPC: G06F1/04
Filed: 1989-12-20
Abstract: PURPOSE:To facilitate the detection and correction of bit synchronization deviation by selecting a level of a head bit of a serial clock and a level of 2nd and succeeding bits to a high level and a medium level respectively. CONSTITUTION:A level circuit 1 and a switching circuit 2 are provided in addition to a pushpull circuit. Then a control signal 8 is used at first to throw the switching circuit 2 to a high level thereby turning on a level switching transistor(TR) 4 of the level circuit 1 and giving a same high level as a power voltage to a high level TR 5. When the transmission of a serial clock 7 is started, the switching circuit 2 is inverted to a medium level at the trailing edge of the initial serial clock 7, resulting that the level switching TR 4 is turned off, then a medium level lower than the power voltage is given to the high level TR 5 through a level drop element 3. The succeeding serial clocks are all sent externally from an output terminal 9 as a medium level output signal. Thus, the detection and correction of bit synchronization deviation are facilitated.
