Title: Liquid helium cryostat
Inventor: YAMADA HAJIME
IPC: F17C3/08
Filed: 1983-07-15
Abstract: PURPOSE:To reduce the heat conducted through the wall of a liquid helium tank and to prevent the deterioration of degree of vacuum of a vacuum heat insulating barrier by a method wherein the material for a lower part of the liquid helium tank is composed of the first metal which is not magnetized by cold working and the material for the upper part which is combined with the lower part is composed of the second metal whose heat conductivity is extremely small compared with the material of the first metal. CONSTITUTION:The first vacuum heat insulating barrier 2 is used for heat insulation between a liquid helium tank 1 and a liquid nitrogen tank 3 and the second vacuum heat insulating barrier 4 is used for heat insulation between the liquid nitrogen tank 3 and the outside. When Al is used for the material of a lower part 1a of this liquid helium cryostat, it is not magnetized by cold working as it is non-magnetic. However, the heat conductivity of Al is extremely large compared with stainless. Accordingly, if the whole device including even an upper part 1b is composed of Al, the liquid helium will rapidly evaporates since the heat enchroachment due to conduction is large. Then stainless is used for the material of the upper part 1b so as to increase the heat resistance thereby reducing the heat conducted through the wall of the tank.

Title: Method for decorating porcelain plate
Inventor: ISHIDA HIDEKI
IPC: B28B1/30
Filed: 1988-05-25
Abstract: PURPOSE:To contrive to simplify decoration such as coloring, spotting and the like and to facilitate the controlling of decoration by a method wherein pigment having the predetermined particle size is added to the suspension of porcelain body as stock. CONSTITUTION:By uniformly dispersing pigment for decorating porcelain plate base in the suspension 16 of body as stock by charging the predetermined amount of said pigment in a high speed dissolving machine 20, the above-mentioned stock is uniformly joined in a formed body 18 so as to decorate the body. When a large amount of pigment, the particle size of which is fine, is used, the pigment is uniformly dispersed in the body. When a plate-like body formed body 18 mixed with said pigment is baked, the color of pigment is developed, resulting in uniformly coloring the body. Further, when the loads of the pigment is far more, the body is colored deeper. When the loads of the pigment is far less, the body is colored lighter. On the other hand, when the pigment, the particle size of which is coarse, is used, the pigments 28 lie sporadically in the body, resulting in producing spotting pattern on the surface of the body of the porcelain plate. Thus, by adding pigment in the suspension 16 of porcelain body as stock as described above, the body is colored or decorated in color or pattern in response to the pigment added.

Title: Perpendicular magnetic recording device
Inventor: KUGIYA FUMIO
IPC: G11B5/127
Filed: 1986-06-04
Abstract: PURPOSE:To improve the reproducing efficiency and the recording characteristic by using a magnetic head in combination with a medium having a perpendicular magnetic anisotropy so as to improve the magnetic field strength in the perpendicular direction in the recorded magnetic field. CONSTITUTION:A gap of a ring type head is made of a nonmagnetic conductive material and the head is used in combination with a magnetic recording medium having the perpendicular anisotropy. In the recording medium having the magnetic anisotropy, a medium with higher coercive force or a thicker film than that of a conventional medium, resulting that the effect of the self-degaussing and recording degaussing operation is relaxed in the vertical recording system. Thus, the residual magnetization of the recording medium is improved resulting in improving the S/N resolution. The reproducing efficiency due to the electromagnetic shield effect for the gap is expected to be improved similarly as the case with the longitudinal recording system.

Abstract: PURPOSE:To prevent an error due to overreach by connecting a base station closest to a central control station among base stations receiving a signal transmitted from a mobile station to an incoming transmission line in a crew radio communication system of a train and disconnecting the other base stations. CONSTITUTION:Radio equipments 52, 53 of base stations 6, 7 receiving a signal from a train 3 activate relay switches SW2, SW3 through the reception of the said signal, connect the incoming transmission line UL to a transmission output terminal T of the radio equipments 52, 53 and the signal from the train 3 is transmitted to a central station 4 via the incoming transmission line UL. Since the relay switches SW1-SW3 are inserted in series with the incoming transmission line, the signal transmitted to the central control station 1 is only the signal from the base station 6 closest to the central control station and the base station 7 and succeeding stations are disconnected from the incoming transmission line through the operation of the relay switch SW2. Thus, a communication error due to the simultaneous transmission of the signal from the base station 6 and 7 is not caused.
