Title: Magnetic recording and reproducing device
Inventor: IWAI MASAYUKI
IPC: H04N5/781
Filed: 1984-08-03
Abstract: PURPOSE:To prolong the life of a magnetic disk by discriminating whether or not the total time for reproduction stored on a memory means exceeds the prescribed time, and shifting a magnetic head to another track when said time exceeds the prescribed one. CONSTITUTION:A memory 35 is a non volatile one whose contents can be saved even if a power source is turned off, and stores the total time for reproducing a magnetic disk 20. A clock from a clock generator circuit 32 is gated by an AND gate circuit 32 with the aid of on/off control signal of a disk motor 25 and inputted to a counter 34. While the motor 25 is rotating, the counter 34 counts the time. The total time is inputted to an over-time detection circuit 37 from the counter 34. When it exceeds the preset time, a signal is transmitted to a stepping motor drive circuit 28 and the memory 35 to drive a stepping motor 26. Then the disk 20 is shifted by one track and the memory 35 is reset.

Title: Production of thick steel plate having excellent low- temperature toughness
Inventor: YOSHIE ATSUHIKO
IPC: C21D8/02
Filed: 1983-09-08
Abstract: PURPOSE:To produce a thick steel plate having excellent low-tem. toughness with less internal defects by subjecting a billet to rough hot rolling and force cooling under specific conditions and subjecting the rolled material to hot finish rolling in the state of having a temp. difference between the surface layer of said material and the central part. CONSTITUTION:A billet or steel ingot is heated to the Ac3 point or above and is thus made austenite then the billet or ingot is subjected to rough rolling at about 0-80% draft. The rolled steel is cooled by force cooling, upon ending of the rough rolling, until the average temp. of the steel plate falls down to the Ar3 point+100 deg.C to cool and harden the surface part. The average cooling rate in the stage of force cooling is made >=3 deg.C/sec when the thickness of the roughly rolled material is <50mm., >=2 deg.C/sec when 50-100mm. and >=0.6 deg.C/sec when >=100 deg.C. The steel plate is then subjected to hot finish rolling at about >=40% draft in the state of having a temp. difference between the surface layer part of the roughly rolled material and the central part thereof. The deformation resistance by rolling is thus made large in the surface layer part and small in the central part and therefore the rolling strain in the finish rolling is concentrated to the central part, by which defects such as porosity, etc. are press-stuck and the internal quality of the central part is improved.

Title: Electron gun
Inventor: YOSHIDA NAOHISA
IPC: H01J29/50
Filed: 1982-09-20
Abstract: PURPOSE:To obtain an inexpensive electron gun without deteriorating the static convergence characteristics by tilting beam transit hole faces on both sides except a center beam transit hole face by nearly the same amount respectively against the normal line of an electron gun axis and forming facing electrode faces with a slant face of the final high-voltage/potential electrode nearly flat. CONSTITUTION:The taper part of a G5 electrode is used on the G4 electrode side of the G5 electrode and a G6 electrode is formed in a flat type so that the static convergence function can be attained by only the taper angle of both faces of the G5 electrode. That is, the force applied to an electron beam is opposite in direction to the electric field E generated in a gap between the G4 and G5 and the electric field E is bent toward the narrower portion of the gap, thereby the electron beam is bent toward the wider portion of the gap, i.e., a center beam, and in addition a force is applied to the wider portion of the gap (accelerating lens at this time) between the G5 and G6 electrodes, thus the objective of static convergence can be attained by these two in combination.
