Title: Manufacture of magnetron
Inventor: BABA HIDEKATSU
IPC: H01J23/40
Filed: 1990-04-13
Abstract: PURPOSE:To omit brazing work without use of an expensive hard brazing material, and to minimize exhausting work, so as to obtain an inexpensive magnetron by carrying out the work for electrically connecting a strap ring as well as an antenna to a vane by welding. CONSTITUTION:A cylindrical part 1 and a vane 2 are formed in an integrated form by extrusion method. An antenna 3 is welded and fixed to the vane 2, through the laser beam irradiation to a welded part. The welding of strap rings 4a, 4b and the vane 2 is also carried out by laser beam welding. In this manufacturing method, there is no need for brazing work at the time of assembling an anode, and a high temperature hydrogen reactor for brazing work is thus unnecessary, while there is no need to use an expensive hard brazing material, and further, since a large quantity of hydrogen is not adsorbed at the time of brazing as in conventional way, exhaustion of a magnetron can be finished in a relatively short period of time.

IPC: G06F11/22
Filed: 1991-04-26
Abstract: PURPOSE:To make the number of flip-flops(FF) almost same to the number of FFs required in actual operation and to facilitate a delay test by outputting the output signals of the correcponding FFs on the basis of a common level control signal by at least all of selection means. CONSTITUTION:The output signals of FFs(301-1)-(301-n) and scan-in data 3004 are selected by selection means using a control signal 3001 to be inputted to a combination circuit 304. When the signal 3001 is set to a 0 level, the outputs of the means 302 become the output signals of the FFs and, when the signal 3001 is set to a 1 level, said outputs become the data 3004. Therefore, the signal 3001 is fixed to the 0 level at the times of actual operation and a DC test. When a delay test is performed, the signal 3001 is set to the 0 level and a DC test pattern is set to the FFs and an external input terminal. The signal 3001 is changed to the 1 level and the outputs of the selection means 302 are set to the outputs of the corresponding FFs to perform the delay test.

Title: Control system of picture display device and controlling method of picture display system
Inventor: YAMAZAKI TATSURO
IPC: H04N5/44
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To simplify the interface between a picture display section and a supply source, to realize the constitution, in which connections are made easy, and to eliminate cumbersome wiring of interface cables even though the picture display section is a thin wall hanging type by time division multiplexing video and audio signals. SOLUTION: A terminal modem 203 receives video signals from a video signal processing section 205, audio signals from an audio signal processing section 210 and control information from a terminal CPU 201 and multiplexes these signals in accordance with timing signals from a timing generating section 204 so that these signals do not overlap with each other and outputs them. Thus, various information exchange between a terminal section 2 and a picture display section 1 takes place on a pair of signal lines only and the connecting cable is made simple and thin. Since the sections 1 and 2 are fundamentally connected by one thin cable, a cable processing is easily executed and the appearance is enhanced even though the picture display section is a wall hanging type.

IPC: G07B13/00
Filed: 1990-04-16
Abstract: PURPOSE:To carry out an automatic closing process under constant conditions even if closing operation is not performed forgetfully by performing the closing process when a decision means decides that the closing process is not performed. CONSTITUTION:When a detecting means 11 detects a specific state of a vehicle, e.g. a door open state, a time measuring means 12 starts time measuring operation at the detection timing. Then the decision means 13 decides whether or not the closing process is performed until the measured time obtained by the time measuring means 12 reaches a specific time. Then when the closing process is not performed before a time-over state is entered, a process executing means 14 performs the closing process automatically. Consequently, even if the closing operation is not performed forgetfully, the automatic closing process is performed under constant conditions.
