Title: Data recording and reproducing device and data recording and reproducing method, recording medium and formating method for the recording medium
Inventor: MAEDA YASUAKI
IPC: G11B7/24035
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To realize an efficient prepit format for an MSR magneto-optical disk and to reduce the number of PLL circuits in a disk player and to improve a transient characteristic. SOLUTION: In recording media including a prepit recording area and an MO recording area, data modulation systems are selected so that a recording and a reproducing are possible by using channel bit clocks having the same frequency and also the recording density in the MO area is higher than that in the prepit area. The recording density in the MO area becomes higher than that in the prepit area by making the MO area to be the area of a super-high resolution system. For example, the recording and the reproducing can be performed in both areas with channel bit clocks having the same frequency by respectively adopting an EFM pulse modulation system with respect to the prepit area and a (1, 7) RLL modulation system with respect to the MO area.  Since the recording and the reproducing can be performed only by changing over data without needing it to change over PLL circuits between the areas and, thus, a load in the cost is small. Moreover, since it is not needed to lower the recording density in the prepit area to the half that in the MO area, an efficient prepit format is realized.

Filed: 1988-09-19
Abstract: PURPOSE:To designate a character in an approximately certain short time independently of the number of candidate characters by extracting strokes of the character in accordance with information of positions of intersections and positions of end points of segments of a segmented character picture to estimate the character. CONSTITUTION:When relations among an end point 1 of a segment, an intersection 2 of a segment, and a contact 3 of a segment are clarified, positions of segments in the character are detected even after the character is decomposed to segments, and thereafter, decomposed segments are used to extract strokes of the character. Since information of intersections, end points, etc., of segments, positional relations between each segment and the other segments are clarified; and when decomposed segments are transposed in the order from the left top to the right bottom, segments 1 to 6 are arranged in order to extract strokes of character 'migi'. When strokes of character 'isi' are extracted in the same manner, strokes indicated by segments 7 to 10 arranged in order are extracted. Thus, even the character difficult to discriminate is easily discriminated, and the recognition result is accurately outputted at a high speed.

Title: Aeration purification apparatus using wave pump
Inventor: MANABE YASUHIRO
IPC: C02F7/00
Filed: 1989-09-09
Abstract: PURPOSE:To purify water by producing relatively high pressurized air in comparison to the height of wave using wave motion energy and feeding it into water. CONSTITUTION:A float 1 of a wave pump A is caused to rock to generate power utilizing wave motion energy to actuate a piston 5 in a cylinder 4 provided underwater. Water in the cylinder is delivered through a pipe 7. The moment the water is sent into a medium tank 10, water level in a water column 11 rises to a level greatly higher than the height of the wave, whereby the air in the column 11 is pressurized. Pressurized air thus produced passes through a check valve 16 and is delivered from a pressurized air delivery pipe 15 at the bottom of the water to the outside. The delivered air effects aeration actions due to the differences in specific gravities between water and air, so that oxygen is fed into the water and flows of water are generated at the bottom of the water, causing thereby purification of the water.
