CONSTITUTION:An environment detecting member 10 comprises a metal film 20 of such an element as having magnetic characteristics and capable of environment detection, formed on the surface of a substrate 19. When the member 10 is caused to rotate at the predetermined speed, a magnetic core 15 parts from the surface of the member 10 by the predetermined floating amount H, and a closed magnetic circuit is thereby formed. A magnetic flux generated in this case is read by a magnetic head 9. When the member 10 is placed under the predetermined environment, moisture, gas or the like adheres to the surface thereof, and such a phenomenon as deterioration, oxidation and corrosion starts on the surface of a metal film 20. Thus, a deterioration section 21 expands, and gradually reaches a separation distance H10 observed between the head 9 and the member 10 at the time of detecting the environment. The magnetic characteristics of a sensor 8 change sensitively in response to the change of the separation distance H. This sensor 8 can be used as an environment sensor, when a relationship is established between the progress of rust and the transition of an environmental condition.

Filed: 1985-08-13
Abstract: PURPOSE:To secure the compatibility of recording and reproducing even in a host system by outputting an index signal to an external controller only when the rotation of a magnetic disc is in a steady state. CONSTITUTION:AND between an index-in signal inverted by an inverter 7 and a ready signal before inversion by an inverter 8 is generated by a NAND gate 10 and is outputted from a connector 3 to the host.

Abstract: PROBLEM TO BE SOLVED: To generate a clock signal without using any LPF by comparing a last and a current read value with each other and controlling VCO according to a setting signal generated by a microcomputer for eliminating the read level difference of a synchronizing signal. SOLUTION: A level generation part 11 detects the level of the synchronizing signal and the setting signal outputted by a control part 10 as the microprocessor corresponding to the detection result is applied, so that the DC voltage outputted by a D/A converter 12 is supplied to the VCO 13.

Similarly, the VCO 13 generates a clock signal synchronized with the synchronizing signal. Consequently, the LPF which is easily affected by noise need not be used and the clock generation circuit is easily designed.

Title: Picture processor
Inventor: IKEUCHI TAKENOBU
IPC: G06K9/20
Filed: 1993-07-19
Abstract: PURPOSE:To automatically perform an optimum picture processing of input picture signals by giving input picture information to a neural network for which learning is performed beforehand and deciding pictures to be finally outputted by the output of the neural network. CONSTITUTION:When the following learning is performed beforehand, the neural network outputs a value close to '1' when a picture element of interest is a character and outputs the value close to '0' in the other cases. The neural network 2 judges whether or not the picture element of interest is the character from a temperature and the picture element and outputs a judged result. The judged result is binarization-processed by a binarization-processing part 3 and is defined as the control signal S of a selector 5. The selector 5 switches over the picture signal for which a pseudo medium gradation processing is performed and the picture signal for which a binarization processing is performed by the control signal to each other and outputs to an output terminal 7. Thus, even when the state of the pictures changes by the temperature, binarized data are outputted when the picture element of interest is the character and pseudo medium gradation processed data are outputted to the terminal 7 at the time of other than the character.

For the band H, a positive voltage is applied to the terminal 3a to connect coils L1 and L2 in parallel, the cut-off frequency of the LPF3 becomes a little bit higher than the upper limit frequency of the band H, and a tuning voltage is applied to the terminal 4a of the BEF4 to attenuate a local oscillation frequency component.
