Title: Electrostatic capacity type acceleration sensor and pressure sensor
Inventor: YOKOYAMA ATSUKO
IPC: G01P15/125
Filed: 1993-01-18
Abstract: PURPOSE:To improve acceleration and pressure detecting accuracies of an electrostatic capacity type sensor. CONSTITUTION:An accuracy of an interval between a movable electrode 41 and a stationary electrode 42 is improved by abutment of a board 10 on a cover 20. Since an end of the cover 20 and the board 10 are fixed to a pedestal 30, the end of the cover 20 is coupled to the board 10 via the pedestal 30. In this case, since the board 10 is merely made to abut on the cover 20, even if there is a difference of thermal expansion coefficients of the board 10 and the cover 20, positional relationship between both of the abutment part is deviated if a temperature is changed, and hence no stress is generated at the abutment part. Since a first vent passage is formed from the outside of the cover 20 to the electrode side 41, a second vent passage is formed from the outside of the pedestal to the electrode side 41 and a pressure difference occurs on both side surfaces of the electrode 41, and hence the electrode 41 is displaced by the difference.

Title: Synchronizing signal detection circuit
Inventor: SHIRAHATA MIYUKI
IPC: H04J3/06
Filed: 1995-02-13
Abstract: PURPOSE: To prevent mis-detection of a PCM audio signal by detecting non- correlation between an input signal and a signal obtained by delaying the input signal by several clocks. CONSTITUTION: A 1st non-correlation detection means 102 detects non-correlation between an input signal and a signal obtained by delaying the input signal by one line. A 2nd non-correlation detection means 103 detects non-correlation between the input signal and a signal obtained by delaying the input signal by 4 clocks. A 3rd non-correlation detection means 104 detects non-correlation between the input signal and a signal obtained by delaying the input signal by 3 clocks. Then a control means 106 controls an up-down counter 107 based on the result of an output of an AND circuit 105 and the up-down counter 107 is counted by an output of the AND circuit 105. A comparator 108 compares the count of the up-down counter 107 with a threshold level (m), and a synchronization discrimination means 109 discriminates a frame synchronizing signal based on the result of the comparator 108.  Thus, mis-detection with respect to a PCM audio signal is prevented and erroneous discrimination of MUSE reception is avoided regardless of reception of the NTSC signal.
