Title: Similar drifting search buoy
Inventor: SHIMIZU YUTAKA
IPC: B63B22/00
Filed: 1980-10-13
Abstract: PURPOSE: To improve search activity efficiency, by a method wherein a search buoy, which has a shape being equalized to a fluid resistance ratio of an air-exposed part of a lifesaving boat to an underwater part thereof, is dropped, and the search buoy is caused to draw a drifting trace similar to that of the lifesaving boat.  
     CONSTITUTION: A similar drifting search buoy is manufactured in the shape in which the product of a projection area S a  and a resistance factor at a side of an airexposed part of a lifesaving boat whereon a victim embarks is equalized to a ratio of a projection area S w  at a side of an underwater part to a resistance factor. If communication on a shipwreck is received, a search plane drops a search buoy at a spot where the shipwreck is estimated to occur. A search is conducted centering around the search buoy serving as a cordinal point, and this prevents the accelerative increase in a search area with the lapse of a time.

Title: Demodulation circuit for reproducing device
Inventor: ONO HARUO
IPC: G11B20/10
Filed: 1988-06-09
Abstract: PURPOSE:To accelerate transfer speed by outputting a PWM signal by compar ing an input reproducing signal setting an input signal from an error detector as reference level. CONSTITUTION:An analog signal outputted from an amplifier 65 is compared at a comparator 66 setting the input signal from the error detector 67 as reference level, then, the PWM signal is outputted. The PWM signal is sent to a level shifter 68 and an LPF69. The cutoff frequency of the LPF69 is set sufficiently low compared with the fundamental frequency of the PWM signal, and an output signal is sent to the error detector 67. To the error detector 67, the output of an LPF70 is inputted. The cutoff frequency of the LPF70 is set sufficiently low compared with the fundamental frequency of the PWM signal, and its control signal CTRL is a signal of duty of 1/2. The detector 67 compares signal levels sent from the LPFs 69 and 70, and detects an error between them, and sends it to the comparator 66. The level shifter 68 performs the level shift of the PWM signal from the comparator 66, then, outputs it as a demodulated PWM signal after performing waveform arrangement on it.

Filed: 1980-10-13
Abstract: PURPOSE:To control a clock rate easily and securely by controlling the writing and reading of a reproduction output to an from a memory by a reproduction clock and a reference clock respectively and by controlling a reproduction speed according to an overflow and an underflow state. CONSTITUTION:The writing of a reproduction output to a memory 21 for jitter absorption is performed through an address counter 24 applied with a reproduction clock, and is reading is performed by an address counter 25 which counts a reference clock.

IPC: H01L21/66
Filed: 1978-11-22
Abstract: PURPOSE: To enable automatic detection of the scribing line on a wafer without visual check nor alignment mark by detecting scattered light from the wafer upon scanning of focused light on the wafer.  
     CONSTITUTION: A focused light 52 is scanned on a wafer 51 to vibrate by sine wave in x- and y-axes directions. There is separately provided a device for receiving scattered light from the wafer 51 of scanned focused light 52. Since the minimum of the received scattered light corresponds to the center of the scribing line on the wafer, the scattered light is detected to measure the displacement of the position from the scanning center of the light 52. The displacement thus measured is fed back to θ stage 54, x stage 55 and y stage 56 to move the position of the wafer 51 to thereby coincide the center of the scribing line with the center of the scanning of the light 52.

Abstract: PURPOSE:To eliminate the need of large labor for the maintenance management, and also, to suppress the deterioration of a vertical orientation property of a magnetic layer by providing a rotary grinding roll for sliding on the surface of a medium between a device for feeding out the medium fed from a drying process and a take-up device. CONSTITUTION:A feed-out roll 1 rotates in the direction as indicated with an arrow (a), and a medium 2 moves in the direction as indicated with an arrow (b). A rotary grinding roll 4 rotates in the direction as indicated with an arrow (c), grinding rolls 8, 12 rotate in the directions as indicated with arrows (d), (e), respectively, and a take-up roll 15 rotates in the direction as indicated with an arrow (f) and winds up the medium 2. Accordingly, when the surface of a magnetic layer of the medium 2 comes into contact with the grinding rolls 4, 8 and 12, a flow is generated on the surface of its magnetic layer, and as a result, the magnetic surface is smoothed, and becomes a polishing state. Since polishing on the surface of the medium is executed in such a way, it is unnecessary that magnetic particles brought to vertical orientation are laid down.

Title: Overflow control system of supernatant water in sludge discharge pond
Inventor: TAKEDA KEIZOU
IPC: B01D21/24
Filed: 1978-11-22
Abstract: PURPOSE: To return stably and reasonably supernatant water to a pool by descending a sluice gate and overflowing the supernatant water in detecting concentration of sludge within a pond.  
     CONSTITUTION: When a concentration detected by a sludge concentration detector 7 is a clear concentration, a sluice gate control circuit 13 receives a concentration signal from a transmitter 12, and a motor M is driven to move a gate 6 downward. Supernatant water overflows the gate 6 into a tank 5, and is returned to a pool by a pump 3 for returning the supernatant water. By the overflowing of the supernatant water, water level is lowered, a float 9 descends, and the sludge concentration detector 7 suspended by a cable 8 descends to the bottom of the pond. When the detector 7 detects a sludge concentration which shows that the pond is not polluted, the gate control circuit 13 receives a concentration signal from the transmitter 12, thereby the driving of the motor is stopped to stop the movement of the gate 6. The gate 6 is restored to its original state by any suitable means, and the overflowing of the supernatant water is stopped.
