Title: Cathode ray tube
Inventor: MURASE YOSHITAKA
IPC: H01J29/50
Filed: 1995-04-26
Abstract: PURPOSE: To maintain a beam control function and prevent shining of a cathode ray tube by arranging a grounded electrode between a grid electrode and an anode electrode, and housing-grounding the grounded electrode. CONSTITUTION: In pin arrangements 1-12 in a socket part, a heater electrode 6 is connected to the pins 1, 12, a cathode electrode 5 is connected to the pin 11, and a first grid electrode 4 is connected to the pin 2. A second grid electrode 3 is connected to the pin 10, and an anode electrode 1 is connected to the pin 6. A ground pin 7 which is a grounded electrode is connected to the pin 4 which does not use these electrodes. Since the pin 7 is arranged and housing-grounded between the electrode 3 and the electrode 1, even if discharge occurs on the inside of CRT (a cathode ray tube), energy is focused on the pin 7 having low impedance, a beam control function is maintained, and generation of spot burning or the like is prevented.

Abstract: PURPOSE:To keep safely and take out simply mails by sending a lock releasing signal to a mail box door opening and closing mechanism corresponding to a card taken in on the basis of a reading signal from a card reader to open the door of the mail box. CONSTITUTION:A user inserts a card into a card receiving port 18 of a card reader 16. When information such as the number read by a card reader 16 coincides with information previously stored in a memory unit of an opening and closing controller, a door of a mail box 10 corresponding to the card is opened by supplying an ON signal to an electric lock 24 with said controller. When a plunger 26a is pushed out to open a door 14, a microswitch 28 is turned off and the opening of the door 14 can be confirmed by detecting the turning-off of said switch through said controller. When the door is not opened, the opening directing operation is repeated three times. When the door is not still opened, the condition is returned to the initial one in which the card can be inserted again.

Filed: 1985-05-15
Abstract: PURPOSE:To put a displacement detector high in resolution into practical use by displaying a mean obtained by a mean arithmetic means on a digital display at every averaged period specified by a timing device. CONSTITUTION:A function button on an operational panel 33 is pressed to select an averaging display. A sampling period and an averaging period are set to 1msec and 1msecX10<2>=0.5sec, respectively, for instance. Then a sampling circuit 34C samples the counted value of a timepiece counting the pulse output of a reversible counter 32 at every msec during the sampling period, and stores it in a memory circuit 34A. On the other hand, a timing circuit 34B operates an averaging circuit 34D by 0.1sec during the averaging period, and said circuit 34D obtains the mean of 100 stored values. The obtained mean is displayed on a digital display 36. A light emitting diode 38 lights up at every averaging period of the circuit 34B. Accordingly the selected averaging period can be visible, and becomes a rough guide when an operator selects an optimum value in accordance with his work.

CONSTITUTION:In the magnetic gap butting surface 40 of a block 31 plural sets of parallel grooves, each set of which is composed of adjacent grooves 41 and 41', are formed, with V-shaped projecting parts being left between each paired grooves. Thin films 33 and 34 made of a magnetic substance having a high saturated magnetic flux density and high magnetic permeability are formed on the entire area of the magnetic gap butting surface 40 by sputtering and a nonmagnetic substance 35 is put in the grooves 41 and 41' to a degree that the remaining spaces of the grooves can be filled up with the substance 35. Then unnecessary nonmagnetic substance 35 and the magnetic film 33 are removed by grinding until a prescribed guard band width (l) is obtained. Thus the 1st and 2nd magnetic core sections are separated from each other and a butting surface is exposed. Thereafter, a specified groove 36 is formed in the magnetic film and a gap forming film is formed by sputtering a nonmagnetic material to a prescribed thickness on magnetic gap forming surfaces 44 and 44'. Then two blocks thus formed are put together with the track widths (tw) and tw' of the blocks being put together, and they are heat-joined under a pressure.

Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To perform highly accurate inspection without causing any trouble in soldering work during mounting process by inspecting a printed wiring board while heating the basic material thereof up to the vicinity of a rated temperature. SOLUTION: Test pins are brought into contact with the circuit to be inspected on a printed wiring board P positioned at an inspecting position by pressing an inspection jig 32 and inspection is performed by supplying a current between test pins. More specifically, conducting state is measured and the circuit to be inspected is checked for conduction and short circuit. During a series of inspections, the wiring board P is heated by hot air blown out from a hot air generator 33 and kept in a temperature range of 100-180 deg.C. Inspected wiring board P is taken out from the jig 32 and carried to a cooling section while being sorted into acceptable one and rejectable one.  Since a rejectable wiring board P can be determined by loading it with thermal stress under such temperature/time conditions as causing no deterioration of the wiring board P before and during wiring board inspection(PWB), trouble of conduction can be prevented after mounting work at a client.

Abstract: PURPOSE:To facilitate removal of permanent curl and the charge of sheets by providing a sheet carrying means to remove a permanent curl of a sheet on a sheet carrying mechanism of a printer or the like and making it possible to release the pressed condition with a pressing member which presses against the sheet carrying means. CONSTITUTION:A recording system W is controlled in such a way that a main frame 1, and a cover body 2 can be opened/closed around a shaft 3. When the cover body 2 is closed, the compression spring 10l of a permanent curl removing part 10 is pushed by a chassis 12 and a discharge roller 10d and a back-up roller 10j come in pressure contact with each other through a carrying belt 10e.

Consequently, a recording sheet 6 is bent in the direction opposite to the curl direction along the carrying belt 10e to reduce or remove the curl of the recording sheet 6. When a sheet roll is charged, a hook 5a is released from a locking protrusion 5b to open the cover body 2.
