Filed: 1987-11-30
Abstract: PURPOSE:To drastically improve working efficiency by setting layout specifying paper on a scanner and adding attribute data at the time of extracting rectangle data by means of a graphic data input device. CONSTITUTION:When an operator sets the layout specifying paper on the scanner 1, an image reader starts to read the image data of the layout specifying paper and the image data of the specifying paper is binarized in a computer 2 to be stored in a magnetic disk device 5 as a line image. And the coordinate data of the read line image is corrected into a normal dimension. The image data is filtered by the computer 2 to be compared with a threshold and when the data is equal to the threshold or above, it is decided as an apex. The image data is sequentially matched with a grid pattern in the rank of high hierarchy and when they coincide, the data is extracted as the apex. Then other three apices which make a set with the apex are obtained. As a result, the coordinate data of a layout range necessary for a layout scanner 7 is automatically detected. The attribute data such as the number of an original, etc., is added to each graphic pattern data with a mouse 4 so as to input them.

Title: Selector cock for water purifier
Inventor: SUZUKI MASAYUKI
IPC: C02F1/28
Filed: 1989-11-24
Abstract: PURPOSE:To protect the water purifier from its thermal damage and to prevent defects of water flow resistance, etc., by winding a torsion coil spring made of a shape memory alloy and used to allow a water supply port to communicate with a second water passage when hot water is supplied to the valve chest on the valve stem adjacent to a ball valve. CONSTITUTION:When hot water is inadvertently allowed to flow while a lever 16 is placed at the A position, the torsion coil spring 29 made of a shape memory alloy is heated by the hot water and deformed, and the valve stem and the ball valve 14 are rotated as shown in the figure. Consequently, the first water passage 5 is forcedly closed, and the hot water is discharged directly into the atmosphere from a second water passage 7 without passing through the water purifier 4. As a result, since the flowing of hot water to the water purifier 4 side is automatically and surely prevented even when the hot water is inadvertently allowed to flow, the main body of the purifier 4 and a filter medium therein are not adversely affected by heat, hence the durability of the purifier 4 is enhanced, and a high fail-safe property is secured.

Title: Tracking control circuit for optical disk device
Inventor: TAKEDA KATSUMI
IPC: G11B21/10
Filed: 1987-12-02
Abstract: PURPOSE:To increase the number of opportunities for leading-in of tracking control to stably and quickly lead in the control by correctly detecting a positive feedback area from a prepit signal and inverting a tracking error signal in this area to form a negative feedback waveform. CONSTITUTION:When the position of a light beam traverses a track, envelopes 54-56 of reproduced signals of pits 50-52 are changed in sine waves. The amplitude 56 of the pit 52 is longer than amplitudes 54 and 55 of two other pits when the light beam is placed on the track, but it is shorter when the light beam is placed between tracks. When pits are equal in size and shape, an average of reproduced amplitudes 54 and 55 of pits 50 and 51 is approximate ly fixed and is equal to the average value of the amplitude of the pit 52. Conse quently, reproduced signal amplitudes of three pits are compared with one another to detect the positive feedback area of a tracking servo system and the polarity of the tracking error signal is inverted to form the negative feed back area. Thus, the tracking control is stably and quickly led in.
