Filed: 1983-03-31
Abstract: PURPOSE:To facilitate the operation of explosion proof treatment by means of shrinking and make such a cathode-ray tube as having no setting metal device manufacurable in an easy manner, by locking an endless-form tension band whose circumferential surface is firmly fitted with plural pieces of section L-shaped supporting metal devices carrying a notched part in its bent part each, to the circumference of a valve face part by means of shrinking. CONSTITUTION:Supporting metal devices 6, 6... for facilitating shrinking operation are installed on the circumference of an endless-form tension band (an explosion proof band) 1. Each supporting metal device 6 is made up in section L-shaped form and in addition, a fixed depth notched part 6' is installed in the inner surface of an L-shaped bent part by means of a press or the like. This explosion proof band 1 is supported by a receiving jig 4, heated for thermal expansion, and a valve 2 is inset in from a face part, then shrunk and locked after being cooled. Next, each supporting metal device 6 is repeatedly bent again and over again from a point of the notched part 6' and cut thereat, then a projection piece (6a) is removed, leaving only the part locked to the explosion proof band 1 behind. With this constitution, such a cathode-ray tube as having no setting metal device for a cabinet or the like is processed with explosion proof treatment by means of shrinking can be secured.

Title: Start-stop data speed automatic recognition circuit
Inventor: MATSUMURA NAOYA
IPC: H04L7/04
Filed: 1990-03-09
Abstract: PURPOSE:To recognize a start-stop data speed automatically by adopting the constitution such that a bit serial character SD sent from an opposite equipment is converted into a parallel data and the converted data is compared with a predetermined reference value. CONSTITUTION:A counter 12 starts counting of a 9.6kHz clock. A shift register 13A converts the input character SD into a parallel data sequentially by using the clock as a shift clock. when four bits in the middle are inverted and the resulting data is inputted to an identification circuit 14A, an output of a flip-flop 15A goes to 8 to inform the detection of a code 21H. When a Q output of the flip-flop 15A goes to 'H', the signal is fed back to in OR gate G2 to close the gate. In this case, since an output of an identification circuit 14B detecting a frequency of 600ps is not the code 21H, the output remains at 'L' as shown in (k) and a Q output of a flip-flop 15B similarly remains at 'L'.

Title: Piezoelectric converter
Inventor: NANBU KENJI
IPC: H04R17/00
Filed: 1986-03-17
Abstract: PURPOSE:To eliminate a lead wire and a soldering operation by forming a case by a conductive material and forming a rear plate as well formed integrally with a contactor part by the conductive material. CONSTITUTION:The case 3 and the rear plate 6 are respectively formed of the conductive material, the contactor part 6a as well is especially integrally formed on the back board 6 to electrically connect metal oscillator 1 with a piezoelectric type ceramic plate 2 directly. Further, a diaphragm 4 is energized and fixed so as to cancel the pressing force of the contactor part 6a to the piezoelectric ceramic plate 2. The electrical connection of the case 3 - the metallic oscillator 1 - the piezoelectric ceramic plate 2 - the contact part 6a - the rear plate 6 can be performed without the soldering operation. The possibility that the oscillation mode between the piezoelectric ceramic plate 2 and the metallic oscillator 1 is deteriorated by the pressing force is cancelled by energizing and attaching the diaphragm 4 so as to apply substantially the same force in an opposite direction to the pressing force of the contactor part 6a.
