IPC: H01J17/49
Filed: 1984-02-27
Abstract: PURPOSE:To obtain a large perspective angle by forming a great number of thin cathodes in the inside of a surface plate for perspective and a great number of thin anodes perpendicular to them in the inside of a back plate, and further providing insulating layers in parts of the surfaces of the cathodes. CONSTITUTION:An envelope is formed by a back plate 1 and a surface plate 2 for perspective, and a great number of thin cathodes 7 arranged in the inside of the surface plate 2 in parallel are provided, in which parts of the surfaces opposing to anodes 8 are covered with insulating layers 9, and the anodes 8 perpendicular to the cathodes 7 are provided in the inside of the back plate 1 in a parallel direction, and further insulating bulkheads 10 for forming scanning spaces are provided along the anodes 8, and the a discharge tube for display is formed. And therefore only the portions in the region of both ends of the cathodes 7 are exploded to the side of the anodes 8 and it is possible to obtain a large perspective angle even if the high density is made in the electrode arrangement because the cathode glow is generated in the only exploded region in discharging, and further it is possible to enlarge the area of each electrode and to reduce the resistance value.

Title: Method and device for multiplex transmission
Inventor: FUNATO MINORU
IPC: H04L5/00
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for multiplex transmission with which plural signals can be transmitted while being multiplexed under simple control at low cost. SOLUTION: At transmission equipment 50, an edge detector 52 detects the change of a data signal from H to L and outputs a synchronizing signal. After the lapse of every basic unit time (the inverse of bit rate), a transmission trigger outputter 53 outputs a transmission trigger and when the synchronizing signal is outputted before the lapse of the basic unit time, the measurement of the basic unit time is started again. Each time the transmission trigger is outputted, a transmitter 56 transmits the data signal and low-speed control signals 1-4 to a transmission line 60 while multiplexing them. A receiver 71 of reception equipment 70 detects the change of the signal received through the transmission line 60 from H to L and outputs a reception trigger.  Each time the reception trigger is outputted, a level holder 73 and a 1:N selector 74 extract and hold the data signal and the low-speed control signals from the received signal.

Title: Code converting circuit
Inventor: IWAKIRI TAKUYA
IPC: H04L25/49
Filed: 1983-03-04
Abstract: PURPOSE:To limit the correlation between fields of data by using the first mark signal of a frame as a bipolar signal having the alternating positive and negative polarities. CONSTITUTION:When a signal of an H level is supplied to an input terminal 15 for control signal, the output -Q of an FF22 is always kept at an H level by an input pulse sent from a frame input terminal 14. Thus only a gate 25 becomes active to function as a conventional mark signal separating circuit. Then terminals Q and -Q are set alternately at an H level when an input terminal 15 is set at an L level. Thus only the mark signal reaches a differential amplifier 21 by capacitors 26-29. As a result, it is possible to obtain a frame signal with which the first mark signal is defined as positive polarity and the subsequent mark signals are defined as positive/negative alternating signals from a bipolar output terminal 16. Then the first mark signal is defined as negative polarity and the following mark signals are delivered alternately with positive and negative polarities.

Title: Parts rack with take-out indicator
Inventor: KUSHIDA HIROSHI
IPC: G06Q50/00
Filed: 1991-02-07
Abstract: PURPOSE:To follow a change in the layout of a parts rack easily by installing light emitting elements and light receiving elements group at upper/lower and left/right guide rails so that they may be adjusted in a facing condition. CONSTITUTION:Upper/lower and left/right light emitting elements 5a-5f, 7a-7c and light receiving elements 6a-6f, 8a-8c are adjusted by sliding so that they may pass through the positions of take-out parts A-M. Besides, when the parts M is drawn out of a parts rack 1, it is detected that the light receiving elements 6f, 8c for two light beams from the light emitting elements 5f, 7c which cross the parts take-out position shuts off light incidence, and it is judged that the parts take-out position meets an indicating position by a judging means 15. When light incidence other than this matching is shut off, a mis-matching buzzer 16 sounds. When parts layout is changed due to a model change or the like, the light emitting elements and light receiving elements are adjusted by moving them along the guide rails 10-13 according to a new parts arrangement. It is thus possible to follow the above layout change for adjustment.

Title: Bilge pump control device
Inventor: TSUKUDA SADAAKI
IPC: F04D15/00
Filed: 1983-03-09
Abstract: PURPOSE:To prevent the idle rotation of a pump by integratedly attaching a water level detecting device to a dirty water suction inlet and always exposing both to the same water level. CONSTITUTION:During any flow of dirty water in a float chamber 74, a lead switch is not opened and a pump continiues its operation even if the level of the dirty water lowers to a level lower than a line X. When such a situation occurs that the atmosphere is sucked in through a sealed hole 77 instead of the dirty water, a flow of the dirty water disappears in the float chamber 74, allowing no dynamic presure caused by a water flow to act on a float 86. Accordingly, the float 86 drops downward due to its own weight to the lower part of a stem 84. Then, the lead switch is opened to open a relay contact to permit a motor to be stopped, so that no idle rotation of the pump may occur.
