Title: Supporting method of angular velocity sensor
Inventor: ICHISE TOSHIHIKO
IPC: G01C19/56
Filed: 1989-09-22
Abstract: PURPOSE:To enable prevention of the fluctuation of an angular velocity output due to the vibration of or a shock on a piezoelectric bimorph element for detection by fitting a sensor to the fore end of a shock absorber which is fixed at one end to an angular velocity detecting case body and has a cantilever structure. CONSTITUTION:An outer case 11 wherein an angular velocity sensor is held is fitted to the fore end of a shock absorber 13 which is fixed at one end to an angular velocity detecting case body 12 and has a cantilever structure, and the opposite directions of a piezoelectric bimorph element for detection and the direction of deflection of the cantilever are made equal to each other. When a shock is given, according to this constitution, the cantilever of the shock absorber 13 is deflected if the modulus of elasticity thereof is lower than that of the piezoelectric bimorph. Consequently, the whole of the angular velocity sensor fitted to the fore end thereof inclines and no deflection occurs in the piezoelectric bimorph element for detection. When a vibration approximating the resonance frequency of the cantilever is impressed, the cantilever is deflected in a large degree and the angular velocity sensor fitted to the fore end thereof shakes to a large extent. If the resonance frequency of the cantilever is set to be low sufficiently, however, the shaking does not affect an output of the angular velocity sensor. Accordingly, the fluctuation of the angular velocity output due to the vibration can be prevented.

Title: Image processing method and device therefor
Inventor: MIURA TAKASHI
IPC: G06T15/02
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a blurring processing and to express more real depth perception by performing a processing by a digital low-pass filter provided with a cut off-frequency corresponding to distance information. SOLUTION: The image data is processed by the digital low-pass filter provided with the cut-off frequency corresponding to the distance information. For instance, a digital low-pass filter of an order n=2m is a filter for performing a data processing by m-stage cascade as shown in Figure. A digital filter, that is a transfer function, is a function of the distance information, that is of a (z) value. Thus, by relating the (z) value and a coefficient (k), blurring corresponding to distance is expressed. In such a manner, by operating a highst frequency included in image data, the effect of being out of focus is expressed. Then, by approximating the vision characteristics of a human by the digital filter of frequency characteristics corresponding to the distance information for the operation, quantitative optional distance setting is enabled.

Title: Optical fiber amplifier
Inventor: YONEDA JUNICHI
IPC: H01S3/0941
Filed: 1992-09-17
Abstract: PURPOSE:To prevent the output of a light signal which is amplified when come- off of an optical connector is detected, by installing an optical switch which changes over an amplified light to a weak light and prevent amplified light from being output. CONSTITUTION:When an optical connector is not connected with an output terminal 20, a photodiode 10 converts a reflected light to an electric signal, which is detected by a detector 12. By using the output of the detector 12, an optical switch 8 changes over a high power source to a laser diode 14 whose optical output power is small. At the same time, in order to cut off the output of an optical amplifier, a laser driving circuit is controlled and the output of a pumping laser diode is cut off. In this manner, the reflected light is detected, the high power source is changed over to a laser diode 14 by using an optical switch 14, and come-off of an optical connector is detected. Thereby a high power light signal is not outputted, so that a safe state is ensured when the light signal enters eyes. Since the reflected light is always detected by the detector 12, the connector coming-off is not released so long as the optical connector is not connected.

Title: Magnetic recording medium and its production
Inventor: HARA YOSHIAKI
IPC: G11B5/64
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To magnetically separate recording tracks and to decrease track edge noises by making regions where ferromagnetic layers ferromagnetically bond to each other and regions where these layers antiferromagnetically bond to each other present and allocating the regions where the magnetic layers ferromagnetically bond to each other as a recording track. SOLUTION: At the thin of film making, the recording layers where the ferromagnetic layers 31 and 33 antiferromagnetically bond to each other over the entire part of the medium are locally heated, thereby, the diffusion of a nonmagnetic layer 32 is induced and the arbitrary regions are made ferromagnetic and a magnetically recordable state is attained. The regions of the recording layers heated by using laser power are annihilated by the diffusion of the nonmagnetic layers into the ferromagnetic layers 31 and 33, thereby, the ferromagnetic layers 31 and 33 are mutually ferromagnetically bonded and are magnetized in the same direction. A laser spot is thereafter moved apart prescribed intervals in the radial direction of the medium to concentrically heat the recording layers.  The antiferromagnetism is maintained in the portions not irradiated with the laser, thereby, the ferromagnetic bond regions and the antiferromagnetic bond regions are alternately produced.
