Patent JP-H01279537-A (JP)
Title: Indirectly heated linear cathode
Inventor: MORIMOTO KIYOSHI
IPC: H01J1/26
Filed: 1988-04-30
Abstract: PURPOSE:To eliminate generation of poor insulation by coating the surface of an insulation layer with thermoelectron emitting substance through a metal conductive layer in the form of a cylinder, and by forming a uniform thermoelectron emitting substance layer. CONSTITUTION:A metal thin wire 4 and a metal conductive layer 3 arranged concentrically on an electric insulation layer 2 for protection of it. Because this metal conductive layer 3 and the wound metal thin wire 4 are in contact and continuity, the resistance of a cathode base 6 becomes low. In case used to a fluorescent light emitting device, the brightness gradient nullifies. Coating of the thermoelectron emitting substance is applied to the insulation layer 2 through the metal conductive layer 3, so that an electron emitting substance layer 5 is formed also on this metal conductive layer 3, which produced uniform electron emitting condition effectively. Further this prevents the thermoelectron substance to the heater core 1 from pinholes in the insulation layer, which eliminates generation of poor insulation.

Title: Earth sensor tester
Inventor: KIMURA MICHIO
IPC: G01C21/24
Filed: 1989-04-28
Abstract: PURPOSE:To remove a vibrational disturbance or the like by irradiating radiation from a pseudo-earth plate on an earth sensor via a rotary reflecting mirror. CONSTITUTION:The positions in the directions of X and Y axes are adjusted by an X-Y moving stage 17 and the positions in an X-Y plane are determined to be fixed. Then, an azimuth angle and an elevation are adjusted by a biaxial angle moving stage 18 and the direction of the field of view of an earth sensor 16 is made agree with a direction in which light radiated from a pseudo-earth plate 11 is received to be fixed. When a rotary reflecting mirror 14 is rotated, the pseudo-earch plate 11 can be scanned and a code width signal from an earth portion 12 can be made incident on the sensor 16 via a fixed reflecting mirror 15. Accordingly, the pseudo-earth plate 11 can be scanned as the sensor 16 is fixed. Thus, after scanning the pseudo-earth plate 11, radiated light inputted to the sensor 16 is converted to electric signals thereby, being supplied to an outside circuit. In this case, since the sensor 16 is fixed, an electric output can be taken out without using a slip ring or the like.

Title: Power supply unit of video tape recorder
Inventor: MATSUBARA TAKASHI
IPC: G11B5/00
Filed: 1978-09-05
Abstract: PURPOSE: To eliminate the need for a main power switch by making it possible to turn ON power through the operation of levers such as regeneration and recording levers, and to turn the power OFF through the operation of a stop lever.  
     CONSTITUTION: Turning one of switches 9, 10, 11, and 12 ON by operating a corresponding regeneration or recording lever closes switch 2. As a result, an alternating-current voltage from plug 3 is applied to terminals (a) and (b) of video tape recorder body 1 and a voltage developed at terminal (c) is applied to video tape recorder body 1, which starts operating. Even if the above-mentioned switch, 9, 10, 11, or 12, would be made open by pushing a stop lever, loading switch 13 is still ON, so that video tape recorder body 1 will be in operation. With loading switch 13 open, however, switch 2 is open, thereby turning the power OFF. Therefore, the need for the main power switch can be eliminated.
