Title: Binder for feed for fish farming
Inventor: HONDO MASAKATSU
IPC: A23K1/20
Filed: 1987-12-07
Abstract: PURPOSE:To obtain a binder providing a feed for fish farming, having reduced kneading time, excellent workability, forming properties, shape retention in water and fine surface of the feed, containing a carboxymethyl cellulose salt pulverized into specific particle diameters. CONSTITUTION:A binder for a feed for fish farming, containing a carboxymethyl cellulose salt pulverized into particle diameters wherein >=80wt.% particles pass through 400 mesh sieve. When the amount of the carboxymethyl cellulose salt is less than 0.1%, the carboxymethyl cellulose salt has no effect as a binder and when the amount exceeds 10%, the binder is economically disadvantageous, balance with other additives is lost and physical properties are conversely deteriorated. Na, K or ammonium salt of carboxymethyl cellulose is preferable as the carboxymethyl cellulose salt and the carboxymethyl cellulose salt having various degree of etherification and viscosity can be used. The carboxymethyl cellulose salt has preferably 500cp viscosity at 1%.

Filed: 1989-11-29
Abstract: PURPOSE:To attain stable traveling guidance by standardizing the outputs of two detecting coils by a maximum output level and using a value obtained by dividing one of the output values of the standardized signals by the other as a steering control signal. CONSTITUTION:A magnetic body lane 11 laid on a road surface 10 is magnetized by the magnetic field of an exciting coil 13 on a magnetic sensor unit 12 set up on a vehicle and the distribution of a magnetic field formed by the magnetization is detected as the output voltage values of the two detecting coils 14a, 14b fixed on the same vehicle symmetrically about the center position with a prescribed interval, so that the relative position of the vehicle to the magnetic body lane 11 can be recognized. In this case, the outputs of the two coils 14a, 14b are standardized by the maximum output level and a value obtained by dividing one of the output values by the other is used as a steering control signal corresponding to the relative position of the vehicle to the magnetic lane 11. Thus, stable steering control can be attained.

Title: Magneto-optical recorder
Inventor: TAKAHASHI KAZUYA
IPC: G11B27/10
Filed: 1989-11-29
Abstract: PURPOSE:To rapidly recognize the infeasible state of detecting a sector mark by a data processing means when this state is effective by canceling a sector mark undetecting signal at the time when a sector mark detecting signal is outputted. CONSTITUTION:A jump requesting signal S2 is once outputted by a jump pulse control means 1 during one rotation of a recording medium disk. After a track jump, a sector mark pattern in a 2-7 code C is detected by a sector mark detecting means 2 to output the sector mark detecting signal 4, and when a signal output means 3 is inputted with the sector mark detecting signal 4, the sector mark undetecting signal S3 is canceled. However, after the track jump, when the sector mark pattern in the 2-7 code cannot be detected by the sector mark detecting means 2 on account of a flaw or dirt, etc., on the disk, and hence the sector mark detecting signal 4 is not outputted, the sector mark undetecting signal S3 is not canceled by the signal output means 3. By this method, when the sector mark cannot be detected, this state can rapidly be recognized by the data processing means, so that a countermeasure can be taken.
