Inventor: YOSHIDA OKIFUMI
IPC: G11B5/588
Filed: 1987-12-09
Abstract: PURPOSE:To remove an azimuth loss and to reproduce a good quality picture by superimposing a driving signal for azimuth control and a driving signal for tracking control and supplying them to a pair of converting elements. CONSTITUTION:A driving signal for azimuth control and a driving signal for tracking control are superimposed and supplied to a pair of converting elements. Namely, an azimuth error detecting means 31 and a driving signal generating means 22 for azimuth control operate an electromechanical converting element mutually in a reverse direction, incline a magnetic head and remove an azimuth error. A tracking error detecting means 27 and a driving signal generating means 21 for tracking control operate the electric mechanical converting element while the head inclination angle, in which the azimuth is corrected in the same direction, is held, and a magnetic head 2 is displaced in a tracking width direction and thus, a tracking error is removed. Thus, an azimuth loss can be removed and a good quality picture can be reproduced.

Title: Method for preventing separation of liquefied organic fertilizer
Inventor: YOKOTA KINYA
IPC: C05G5/00
Filed: 1987-12-09
Abstract: PURPOSE: To improve the preventing effect of the lowering of flowability and the separation of a liquid organic fertilizer by blending an emulsifying surfactant in a fat and oil and mixing the fat and oil in the liquid organic fertilizer.  
     CONSTITUTION: The surfactant such as an anionic surfactant, a nonionic surfactant is blended in the liquid fat and oil consisting essentially of a triglyceride in the ratio of 0.5-50%. Next, the fat and oil is mixed with the previously prepared liquid organic fertilizer in the ratio of 0.01-5%. As a result, the emulsion state of the fat and oil is destroyed and the specific gravity of the whole dispersoid is lowered. In the case of crystal growth of an inorganic salt, the fat and oil stuck to the surface of the crystal obstructs the growth of the crystal. Then, the lowering of flowability of the fertilizer is prevented and separation preventing effect is improved.

Title: Disk reproducing device
Inventor: KONDO KOICHI
IPC: G11B20/10
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce the necessary memory capacity by storing only a part (name of music and name of performer) of text information of a disk in advance prior to reproduction of a track to be reproduced in the disk, then starting reproduction of that track, and intermittently storing other text information. SOLUTION: In reproducing a disk in which at least music information and text information are recorded at different positions, only the name of tune and the name of performer (name of singer) are first read into a RAM 1d. When a track to be reproduced of the CD is designated, reproduction of that track is first started. Music data of the track is read out at a double speed, then stored in a memory 5 and outputted at a normal reproduction speed. The remaining text data is read out during a time margin thus obtained, and music data is read out again at a double speed before the stock in the memory 5 is removed. By thus combining the shock-proof function of the CD, the necessary capacity of the RAM 1d can be significantly reduced without interrupting actual reproduced sounds.

Title: Oxide superconductor and manufacture thereof
Inventor: TANAKA YASUZO
IPC: H01B12/04
Filed: 1991-10-29
Abstract: PURPOSE:To provide an oxide superconductor having excellent thermal-impact resistance, machinability, and superconductive characteristics, and a method of manufacturing the same. CONSTITUTION:In an oxide superconductor wherein a desired number of oxide superconductive material layers 4 are made composite into a silver matrix layer 1, oxide superconductive particles 2 are dispersed in the silver matrix layer 1 in a manner that the density thereof more increases toward the oxide superconductive material layers 4. The difference in thermal expansion coefficient between the oxide superconductive material layer 4 and an outer peripheral siliver layer 5 is made small, so that defective adhesion between the oxide superconductive material layer 4 and the silver matrix layer 1 due to cryogenic cycle during use is prevented. Further, since the difference in deformability between the oxide superconductive material layer 4 and the silver layer 5 is gradually changed, the oxide superconductor has a good machinability and has a good shape of oxide superconductive material layer. In addition, since the outermost periphery is the silver layer 5, the oxide superconductor has a good electric stability and excellent superconductive characteristics.

Title: Disk controller
Inventor: YOSHIZATO SATORU
IPC: G06F3/06
Filed: 1989-11-29
Abstract: PURPOSE:To restore a disk where off-track trouble occurs without analyzing an error history by informing a host device that the off-track trouble occurs to the disk when a reread of data from the disk is successful. CONSTITUTION:If a read error occurs while a hard disk drive 3 reads data out of the disk, a disk control part 1 sends a request for an offset reread to the hard disk drive 3, which makes the offset reread according to the request. When data is read out of the disk normally, the disk control part 1 decides the success of the reread and sets a signal indicating the occurrence of the off-track trouble in a register 4. The signal set in this register 4 is sent out to the host device 5 through a transmission line B at the end of the read of the data from the disk or at an optional point of time. Consequently, the disk where the off-track trouble occurs can be restored without analyzing the error history.
