Title: Method for manufacturing explosionproof cathode ray tube
Inventor: JINPOU MASANORI
IPC: H01J29/87
Filed: 1982-06-29
Abstract: PURPOSE:To weld lugs correctly at predetermined positions in the process to fix the lugs to a tension band or a heat-shrunk band fitted around the sides of a panel of a cathode ray tube, by non-contact heating with a laser beam or the like. CONSTITUTION:The tension band 12 is fitted around the sides of the cathode ray tube panel 11, and then, a lug 13 is fixed by laser welding to the band at the position corresponding to each of four corners of the panel, after being correctly positioned by means of a jig. Namely, the lag 13 is provided with a hole 14 at the position where it is welded to the band 12, and the welding is performed by applying laser beams at the circumferential edge of the hole 14 and the side edge 15 of the lug. By welding in this way, input of the laser beam is limited to a small local portion and the welding is performed without making contact with the members to be welded, the lug can be securely welded to the band and no damage is caused on the panel. Since the lugs can thus be fixed to the correct positions, there is no annoyance to be caused when the cathode ray tube is mounted on the cabinet or the like.

Abstract: PURPOSE:To improve a processing efficiency of a computer by inputting a signal of a rotary sensor to an interrupting terminal by using a computer containing a timer, and fetching a value of the timer as a rotational period by a interrupting signal of the interrupting terminal. CONSTITUTION:One magnet 2 is placed on a revolving shaft 1, and a microcomputer 4 decides a magnitude of a load by inputting a signal of a temperature sensor, determines a combustion quantity basing on a magnitude of the load, and determines an opening degree of a fuel valve and a number of revolution of a motor of an air blower. For instance, as for a built-in timer T and a soft timer, when time counting is started, an FF of a hexadecimal is inputted as an initial value, respectively, and the built-in timer is counted down by ''1'' at every 128mu seconds and becomes zero at every 32.8m seconds. At the time of timer interruption processing P1, the soft timer is counted down by ''1''. As the motor rotates, a pulse of LOW is generated from a Hall IC, transferred to an external interruputing terminal 5, and the microcomputer 4 executes an external interruption processing P2 for calculating a rotational period.

On the other hand, the remained part of the refined air flow is further compressed with a booster compressor 18, and the compressing heat is removed with an after-cooler 20, and then, this air flow is passed through the main heat exchanger 8 to form the liquid air, and this liquid air is supplied from the bottom zone of the high pressure rectifying tower 14 toward the upper part.  In the high pressure rectifying tower 14, the elevating gaseous air flow and the lowering liquid air are brought into close contact to produce the oxygen-enriched liquid air fraction at the bottom part and gaseous nitrogen fraction at the top part. By this method, the oxygen-enriched liquid air fraction for supplying a gas containing 97-98vol% oxygen useful for the steelmaking process and the iron-making process, is obtd.
