Title: Cathode-ray tube
Inventor: WATANABE TETSUYA
IPC: H01J29/87
Filed: 1982-06-16
Abstract: PURPOSE:To achieve explosion-proof of a cathode-ray tube main body by fastening force of a fastening material having no looseness of a connecting part by fastening and fixing in the surroundings of a cathode-ray tube main body by temperature change a ring-shaped fastening material comprising a shape memorizing alloy. CONSTITUTION:A ring-shaped fastening material 8 consists of a shape memorizing alloy having a transformation temperature of -150 deg.C, and machined to a desired shape fitting to the surroundings 1d of a panel and converted to a martensite phase at a temperature of less than -150 deg.C. In the material state of the martensite phase, the dimension of the fastening material 8 is enlarged so that the dimension of the fastening material 8 becomes larger than that of the fastening material installing part, that is, that of the surroundings 1d of the panel. When this fastening material is placed in an atmosphere of room temperature, the material returns from martensite phase to austenite phase and automatically decrease its dimension by remenbering the original shape. As a result, the fastening material 8 is fixed in the surroundings 1d of the panel.

IPC: H02P7/28
Filed: 1980-07-30
Abstract: PURPOSE: To prevent abnormal voltage rise in a circuit when connection between a smoothing circuit and a power source is breaked by parallel istallation of a high speed switch along a field coil in an electric motor.  
     CONSTITUTION: On normal operation a current flows along the circuit CH-A-F-L2- CH when a chopper circuit CH is switched on and an electric power is transmitted regeneratively through the circuit A-L1-E-D-L2-F-A to a power source E when the chopper circuit CH is switched off. A capacitor C for a regenerated power smoothing is charged on regeneration and discharged when the chopper circuit CH is switched on. A thyristor SCR is ignited when an X marked line is breaked. By this ignition a power which is stored in a field coil F and a series reactor L2 is discharged by shortcircuiting with the thyristor SCR and can not reach the capacitor C. Therefore generation of an abnormal high voltage can be prevented.

Title: Detecting circuit for cpu runaway
Inventor: TSUNETOMI HIROSHI
IPC: G06F11/30
Filed: 1988-04-28
Abstract: PURPOSE:To quickly and surely detect the CPU runaway by carrying out the reading and writing actions in the fixed order via a CPU and transmitting either one of the detecting signal and the time-up signal of a timer circuit that is produced first in case the wrong executing order is detected for said reading and writing actions. CONSTITUTION:The order monitor circuits 2-6 are provided to monitor the executing order of the reading and writing actions which are carried out by a CPU in the fixed order and produce a resetting signal (g) and a detecting signal (f) with the correct executing order and the wrong one respectively. In other words, a timer circuit 1 is repetitively reset when the executing order of the CPU is correct. Thus a time-up signal (h) is not delivered. While the circuit 1 is not reset in case the executing order is wrong. Then the time counting action of the circuit 1 is continued and at the same time the signal (f) is produced. As a result, either one of both signals (h) and (f) that is produced first is sent to the CPU. In such a way, the CPU runaway can be detected quickly and surely.
