Patent JP-S62120521-A (JP)
Title: Power supply circuit
Inventor: ONO MASAYOSHI
IPC: H01L31/04
Filed: 1985-11-20
Abstract: PURPOSE:To prolong the lifetime of an optical electromotive device by supplying the capacity charged by the electromotive device to the load to reduce smoothly the deterioration of the electromotive device in case an element detecting the luminous intensity of the optical electromotive power detects the luminous intensity higher than a prescribed level. CONSTITUTION:The voltage Vd at the cathode side of a Zener diode 6 is lower than the absolute value ¦Vb¦ of the breakdown voltage of the diode 6 at a low level of luminous intensity. Thus the energized current is kept at a low level, therefore the input and output voltages Vi and Vo are set at low levels. Then a transistor TR2 is kept off. At a high level of luminous intensity the output voltage of an optical electromotive device 1 rises up and both capacitors 7 and 10 are charged. At the same time, the energy is supplied to the load 13 from the device 1. When the voltage Vc of the positive polarity of the capacitor 10 reaches the breakdown voltage level of the diode 6, the voltage Vc is set at a fixed level. Then the voltage Vo of a Schmitt trigger circuit 3 rises up to the level of the Vc when the Vi reaches its highest level. Thus the TR2 conducts and the device 1 is short-circuited. Then the charged electric charge of the capacitor 7 is supplied to the load 13 via a resistance 4. Thus the deterioration of the device 1is reduced.

Inventor: MIYATAKE TAKAFUMI
IPC: G06F17/30
Filed: 1993-10-20
Abstract: PURPOSE:To perform video retrieval fast like text retrieval by performing collation based upon a character string derived from the feature quantity of video for the video retrieval. CONSTITUTION:The video to be retrieved is sequentially inputted, frame by frame, and temporarily stored in a memory. A representative frame extraction part GO detects a scene change from a frame image 27 in the memory by referring to the frame images before and after it and extracts a frame image 28 at the time of the detection. A character string conversion part 21 converts the frame image 28 into a character code string 29 on which its feature is reflected. Then a video name generation part 22 stores a constant-length shift register with the character code string sent from the character string conversion part 21. The character code string stored therein corresponds to the frame image string constituting the video and is outputted as a video name 30. A user, on the other hand, registers video for inquiry, indicates the start of the retrieval, and confirms the retrieval result at an interactive processing part 23.

Title: Magnetic disk device
Inventor: AIKAWA TAKASHI
IPC: G11B5/09
Filed: 1984-12-11
Abstract: PURPOSE:To obtain the time distance of a constant negative signal, and to remove the negative signal by one delay line and to obtain a normal playback signal by setting the physical quantity of a head corresponding to variation in peripheral speed. CONSTITUTION:Inner and outer data zones on a magnetic disk surface 2 are divided, and recorded and reproduced by plural thin-film magnetic heads, and a waveform equivalent circuit 6 which mixes a thin-film playback signal with a signal obtained by delaying a negative edge by a specific quantity through the delay line is provided. The ratio of the sum of the thickness and gap length of the pole 11 of a thin-film magnetic head 1 is equalized to the peripheral speed ratio of each thin-film magnetic head. The time distance of the negative signal is determined by the physical quantity (2 X pole thickness + gap length) of the heads and the relative speed (peripheral speed) of a head medium, and then the quantity of 2 X pole thickness + gap length is varied according to variation in peripheral speed. Therefore, the ratio of 2 X pole thickness + gap is set to 1:2 when an inner-side peripheral speed is 1 and an outer-side speed is 2. Consequently, the negative signal is removed to obtain the normal playback signal.
