Title: Cathode body structure
Inventor: SANO KINJIRO
IPC: H01J1/24
Filed: 1989-08-02
Abstract: PURPOSE:To enable the quick appearance of a picture image by shortening time from the start of electrification to that of electron emission by forming a heat-resistant black film on a heat-resistant insulation substrate. CONSTITUTION:A heat-resistant black film 7 is adherently formed on a part except a surface where the heating element 5 of a heat-resistant insulation substrate 1 is formed. When voltage is applied from a heater terminal 6, each of heating elements 5a-5c generates heat by Joule heat, and when a substrate metal 2 reaches a high temperature of about 800 deg.C, electron emission is stably made. At this time, the temperature of the black film 7 too becomes a high temperature of about 800 deg.C, the more temperature becomes higher, the more heat radiation loss from the insulation substrate 1 increases, and large input power is required to maintain an action temperature of about 800 deg.C. As a result of the increase of input power for heating the heating element 5, the temperature rise rate of the insulation substrate 1 after switch-on is quickened. This causes electron emission to be quickened to enable the quick appearance of a picture image.

Title: Magnetooptical recording apparatus
Inventor: ASANO RYUICHI
IPC: G11B19/02
Filed: 1994-08-25
Abstract: PURPOSE: To increase a repeated reproducing number of times and use an apparatus stably for a long time. CONSTITUTION: An auxiliary magnetic field generating part 21 is arranged at an upper side of a magnetooptical disc 11 and a permanent magnet 23 is rotatably fitted inside the generating part 21 by a bearing 24. The permanent magnet 23 is rotated by a magnetic field generated by a coil 25 and controlled so as to face a magnetic pole S or a magnetic pole N to the magnetooptical disc 11. At a still reproduction mode, similar to a recording mode, the S pole of the permanent magnet 23 is opposed to the magnetooptical disc 11. Therefore, an auxiliary magnetic field is in the same direction both in the still reproduction mode and in the recording mode.  If the auxiliary magnetic field is directed in the same direction as in the recording mode, a repeated reproducing number of times grows ten times in comparison with when the auxiliary magnetic field is directed in the same direction as in an erasure mode. Accordingly, this magnetooptical disc apparatus 1 enjoys an improved repeated reproducing number of times as compared with the prior art not controlling the direction of the auxiliary magnetic field.

Abstract: PURPOSE:To measure the stress of an iron reinforcing bar without cutting the bar by sticking a strain gage on the iron reinforcing bar and forming a groove on the outer layer of the iron reinforcing bar close to the gage and measuring the stress of the bar. CONSTITUTION:First, a rib 3 of the iron reinforced bar 2 is exposed crawling in a groove shape along the surface of concrete and after the surface of the rib 3 is ground and smoothed, the strain gage 5 is stuck on the rib 3. Then, the gage 5 measures a minute strain of the iron reinforcing bar 2 in the longitudinal direction by the expanding and contracting of an electric wire 5a made of copper alloy or the like in accordance with the strain of the iron reinforcing bar 2. Then, the groove 6 is formed by cutting deep into the rib 3 close to the strain gage 5 using a hacksaw or a metallic file or the like. Then, since the stress acting on the iron reinforcing bar 2 is released partially and the quantity of strain of the iron reinforcing bar 2 is changed by forming the groove 6, the variation of the quantity of strain is measured by the strain gage 5 and the stress acting on the iron reinforcing bar can be measured based on the measured value.
