Inventor: FUKUDA TAKAYOSHI
IPC: G01B5/24
Filed: 1989-12-20
Abstract: PURPOSE:To easily protect a fluctuating angle detecting part from jumping stones, mud, and the like, by providing the fluctuating angle detecting part on the upper end part side of a damper supporting fluctuatable rear arms rotatably supporting a rear wheel on their rear ends. CONSTITUTION:A pair of right and left rear arms 11 are pivotally supported with a seat pillar 2, and a damper 13 provided with a variable damping force generating device (not shown in the figure) is provided between the cross member reinforcing the front end parts of the rear arms 11 and a seat rail 3.

Title: Acceleration sensor
Inventor: TANAKA KOJI
IPC: G01P15/125
Filed: 1993-12-24
Abstract: PURPOSE:To raise the self-diagnosing signal outputting level of an acceleration sensor and improve the responsiveness of the sensor by forming through holes in one electrode and providing air damping reducing grooves formed through the through holes by etching in a semiconductor section. CONSTITUTION:Of metallic electrodes 7 and 9 for self-diagnosis, the electrode 7 on a silicon pedestal 5 side has through holes 9 arranged in a plurality of rows. Air damping reducing grooves 10 having end sections opened on the outside of both end edges of the electrode 7 are formed in a semiconductor section which is in contact with the electrode 7. Since the effective area of the electrode 7 which contributes to the impression of an electrostatic force at the time of self-diagnosis is such that the areas of the holes 9 are negligibly small as compared with the whole overlap area of the electrodes 7 and 8 while the areas of the holes 9 are invalid, the self-diagnosing signal of this acceleration sensor is maintained at a high output level. At the time of detecting acceleration, an overlapping section 3 is displaced and a gas in an air gap enters the grooves 10 through the holes 9 and goes out from the openings 10a of the grooves 10. Therefore, air damping is relieved and the responsiveness of the sensor is improved.

Title: Modified duo binary demodulator
Inventor: IGAI KAZUNORI
IPC: H04L27/06
Filed: 1990-11-27
Abstract: PURPOSE:To correct it when phase information of a modified duo binary SSB signal is momentarily in error and to decrease an error rate by applying zero- degree hold to it when a modulated wave is an upper side band(USB) signal and a phase detection output being a monotonous increase is decreased so as to correct the result to a monotonous increase signal. CONSTITUTION:When a USB signal of a modified duo binary SSB signal resulting from phase information mapped with amplitude information is inputted, a phase detection circuit 2 extracts only the phase information from the modulated wave and its phase signal is outputted. Succeedingly, a phase correction circuit 3 outputs a signal with an amplitude just before the reduction till the amplitude is again increased when the amplitude of the phase signal is decreased to apply correction processing to the decreased signal into a monotonous increase signal and a low pass filter 4 is used to suppress a harmonic component of the signal caused attended with the correction processing. Thus, even when a large distortion is exerted to the phase signal due to noise or fading or the like, the signal is corrected by using a property in which the phase of the USB signal is monotonously increased. Thus, the error rate at the transmission is reduced.
