Patent JP-H0757672-A (JP)
Title: Electron gun
Inventor: KOMATSUBARA TAKAO
IPC: H01J37/073
Filed: 1993-08-09
Abstract: PURPOSE:To provide an electron gun by which printing out in the electron gun can be carried out efficiently and a degree of vacuum inside of the electron gun can be maintained high in an electron gun working condition. CONSTITUTION:When printing out is carried out by an internal heater 11, air is exhausted from inside of a jacket 5 by a vacuum pump 13 through a hole 6 and an exhaust pipe 12. As a result, since the air is exhausted from inside of the jacket 5, heat conduction becomes remarkably small in a jacket 5 part, and release of heat from a positive electrode 3 part is reduced, and a temperature in the negative electrode 3 part can be raised, and the printing out can be carried out efficiently. On the other hand, in an ordinary electron gun operating condition, a medium supply pipe 14 is connected to a joint 7, and cooling water is circulated inside of the jacket 5 from a medium supply unit 15. As a result, since a positive electrode 4 is cooled, the positive electrode 4 is not heated to a high temperature by heating of a lens 8, and an emission gas quantity is also extremely reduced, and a degree of vacuum inside of an electron gun chamber can be prevented from deteriorating in a working condition.

Title: Cast molding method for slurry and manufacture for calcined product of ceramic
Inventor: SUGAI ATSUSHI
IPC: B28B1/28
Filed: 1989-07-28
Abstract: PURPOSE:To improve the production yield, by a method wherein a deformation/injury in a demolding and handling processes are make hard to occur and also the deformation at the time of calcining is reduced due to a reinforcement effect of an inwardly projected fringe thick part formed on both end fringes of a belly part. CONSTITUTION:A thickened layer (a) which is formed when strong centrifugal force is acted upon slurry S with high-speed rotation of a water absorption mold 1 becomes almost a fixed thickness extending over the whole of an axial direction. At a point of the time when the thickened layer (a) arrives at a fixed thickness, a rotation speed of the water absorption mold 1 is reduced and the centrifugal force to the slurry S is mitigated. Unsticking slurry S generates doughnut-board-like extensions S2 running along the surface of lid parts 12, 12 with actions of absorbing force on both end spheres of a sleeve 11. Thickening is performed with the whole quantity of the unsticking slurry S under a low-speed rotation and a hollow and cylindrical ceramic molded body A possessing doughnut-board-like fringe thick parts A2, A2 projected inward on both end fringes of a hollow belly part A1 is formed. The hollow and cylindrical ceramic molded body A is superior in resistance to a deformation and injury since the doughnut-board-like inward projected wall thicknesses A2, A2 on both the ends of the belly part play a roll of a rib of a reinforcement member.

Title: Magnetic powder, its manufacture, and magnetic recording medium
Inventor: NAKAZUMI TETSUYA
IPC: H01F1/06
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To manufacture magnetic powder which can suppress an increase in noise after a magnetic recording medium using this magnetic powder is run for a long time and has higher durability and a higher corrosion resistance by forming a ferrite layer composed mainly of iron and cobalt on the surface of each acicular particle containing iron and cobalt. SOLUTION: In a method for manufacturing magnetic powder, acicular particles containing iron and cobalt are first reduced. Then a ferrite layer composed mainly of iron and cobalt is formed on the surface of each particle by oxidizing the reduced particles in a high-temperature atmosphere higher than a room temperature. In the acicular alloy magnetic powder, the mixing ratio of the cobalt against the iron is adjusted to about 5-50 wt.%. The major- axis and aspect ratio of each particle are respectively adjusted to about <=0.25 μm and about 4-8 respectively. Moreover, the ferrite layer is coated with at least either one of Si and Al. Therefore, the occurrence of such a phenomenon that dropout or noise increases can be suppressed when a magnetic recording medium using the magnetic powder is kept in a corrosive environment and the output is high.

IPC: G11B5/027
Filed: 1983-10-26
Abstract: PURPOSE:To obtain an excellent reproduced sound and also to decrease disturbance to the reproduced picture quality by bringing two sound carrier frequencies in the helical scanning type magnetic recording and reproduction to a specific number of multiple of the frequency of a horizontal synchronizing signal. CONSTITUTION:The FM sound carrier is used twice and both frequencies are brought into an integral number of multiple of the frequency fH of the horizontal synchronizing signal. That is, the 1st sound signal 1 is inputted to an FM modulation circuit 38, where the signal is frequency-modulated and the result is fed to a mixing circuit 39. An output of the circuit 38 is inputted to a frequency division circuit 40, and after n1 frequency division, the result is fed to a phase comparator circuit 41. Then the carrier frequency f1 of the FM modulation circuit 38 is locked to the relation of f1=n1.fH/2 through the constitution of PLL. The 2nd sound signal 1' is inputted similarly to an FM modulation circuit 43 so as to lock the carrier frequency of the FM modulation circuit 43 in the relation of f2=n2.fH/2. Thus, the f1, f2 are fixed stably so as to bring the beat frequency to a frequency having a minimum energy of the spectrum of a low frequency chroma signal.
