Title: Shock absorber control system
Inventor: KASHIMA MITSUHIRO
IPC: B60G17/015
Filed: 1993-08-16
Abstract: PURPOSE:To enhance the comfortableness, manevering stability, and the grounding characteristic by changing over the damping force of a shock absorber into the optimum value within a number of frequency regions (resonance areas) according to the frequency of the input vibration and the vibrating speed. CONSTITUTION:A vibrating frequency is determined on the basis of the variation of the vibrating speed signal given by a speed sensor 1, and a frequency judging means 2 makes judgement in which scheduled frequency region the vibrating frequency lies, i.e., the low, middle, high, or beyond them. Meantime, the speed judging means 3 makes judgement in which scheduled speed region the vibrating speed given by the speed sensor 1 lies. Selections are made by a damping force selecting means 5 in conformity to the results from judging-i.e., high damping force in the low frequency region (primary resonance range), low damping force in the middle frequency region, and high damping force in the high frequency region (secondary resonance range). Shock absorber 7 is driven by this driving means 6 in accordance with the selected output of damping force.

Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To detect dissolving of an image from an image signal at a high speed by detecting whether the image is dissolving-in or dissolving-out based on an image signal by two frames supplied continuously. SOLUTION: When an absolute value of a difference between a total luminance of an original image signal by one frame and a total luminance of an image signal by one frame adjacent just before or just after the original image signal is comparatively high and there exist many numbers where an absolute value of a difference between pixels in existence at the same positions spatially with respect to pixel data of the original image signal and pixel data in the adjacent image signal is comparatively small, the image based on the original image signal is discriminated to be dissolving. In this device, a delay image data signal Dn-1 read with a delay by, e.g. a frame memory is fed to a dissolving discrimination circuit 100. That is, image data signal Dn and delayed image data signal Dn-1 of one preceding frame are fed to the dissolving discrimination circuit 100.

Title: Stereoscopic television telephone
Inventor: KUWABARA HIDEO
IPC: H04N13/00
Filed: 1986-09-20
Abstract: PURPOSE:To obtain the eye contact to the other party by image picking-up and transmitting pictures R and L while plane image pickup elements scan parts other than the aperture of a lens in a plane display device. CONSTITUTION:The plane display device 21 alternately displays the received pictures R and L, and a polarizer 22 passes through only light polarized in the a fixed direction among light outputted from the plane display device 21. In synchronization with switching a display screen, a liquid crystal cell 23 outputs the light polarized in the direction as it is or by rotating it by 90 deg.. Consequently the pictures R and L are alternately displayed through lights in different polarization directions. A caller uses polarization glasses which have a polarization lens corresponding to the picture R and a polarization lens corresponding to the picture L. The plane image pickup elements 261 and 262 stop scanning while the plane display device 21 is scanning in the apertures of lenses 251 and 252. While the device 21 is scanning other parts except for the apertures, the elements 261 and 262 operate, decompose the image of the caller which is formed through the lenses 251 and 252 to the pictures R and L, pick up images and transmit them.

Filed: 1992-08-24
Abstract: PURPOSE:To transmit a burst data signal without a transmission requiring signal, by forming a light emitting element driving circuit by connecting a light emitting element, a switching circuit, and a curent amplifier in series. CONSTITUTION:The title light emitting element driving circuit is formed by connecting a light emitting element 5, a switching circuit 8, and a current amplifier 11 in series. Thereby a burst data signal without transmission requiring signal can be transmitted. For example, in the case that a switch in the switching circuit 8 is connected with a current source 10 when an input data signal is 'H', the difference current between a current flowing through a photo detector 6 and the current of the current source 10 is applied to the current amplifier 11. When the current of the photo detector 6 is small, i.e., the light output of the light emitting element 5 is small, the output terminal end current of the current amplifier 11 becomes small, and the current flowing through the light emitting element 5 increases, so that the light output of the light emitting element 5 is increased.

Title: Gyroscope device
Inventor: HOJO TAKESHI
IPC: G01C19/5614
Filed: 1984-10-25
Abstract: PURPOSE:To prevent variation in scale factor and deviation in zero point by arranging a driving coil so that a magnetic field produced with an AC current makes one round of oscillators in series. CONSTITUTION:Driving coils 14 and 14A are arranged under a couple of legs 11 and 11A and coils 14 and 14A are connected in series to flow an AC current. At this time, one of oscillation mass parts 11-1 and 11-1A of both legs 11 and 11A becomes an N pole and the other becomes an S pole at every half cycle of the AC current, so that they receives mutually attracting forces. Therefore, both legs attract each other twice in every cycle of the AC current, so a tuning fork 1 oscilates at a frequency twice as high as that of an AC power source 16. At this time, oscillations of both legs 11A and 11 are detected by oscillation detectors 1l8 and 18A and angular oscillations of the inflection shaft 3 of the tuning fork 1 is rectified synchronously on the basis of the detection outputs to detect an angular speed OMEGA. The driving force which causes the tuning fork 1 to oscillate is only the attracting force between both legs 11 and 11A, so that variation in scale factor and deviation in zero point corresponding to variations in the voltage and frequency of the power source are prevented or reduced greatly.
