IPC: H01J17/49
Filed: 1992-11-07
Abstract: PURPOSE:To obtain the subject element, having a specific Mn-activated zinc silicate fluorescent substance, overwhelmingly bright at a high brightness due to the use of a fluorescent material capable of manifesting the high brightness by exciting with vacuum ultraviolet rays and useful as a plasma display, etc. CONSTITUTION:The objective element has a manganese-activated zinc silicate fluorescent substance of the formula (X has a value of 0.01<=X<=0.2; a has a value of 0.5<alpha<=1.5). The fluorescent substance of the formula is obtained by dry mixing, e.g. a fluorescent substance raw material composed of ZnO, MnCO3 and SiO2, adding MgF2 and NH4Cl as a flux, sufficiently pulverizing and mixing the resultant mixture in a ball mill, then placing the pulverized powder in a quartz crucible, burning the powder at 1250 deg.C for 3hr, dispersing the prepared fluorescent substance in water with a ball mill, subsequently separating and drying the resultant fluorescent substance. The element is obtained by mixing, e.g. particles of the fluorescent substance of the formula with a PVA solution, octanol and an aqueous solution of ammonium dichromate and coating an anode of a plasma display panel with the resultant slurry.

Title: Printing device
Inventor: TAKAHASHI ZENJI
IPC: G03G21/00
Filed: 1989-12-14
Abstract: PURPOSE:To reduce the consumption of a photosensitive drum with respect to the number of a printing by selecting one of two printing methods according to the length of an average intrval between the sending of a paper hopping instruction. CONSTITUTION:A first control part sends a first printing starting instruction to a second control part when an interval between the reception of printing data is shorter than a reference value. Moreover, the first control part detects an interval between the reception of the printing data from an outside device and sends a second printing starting instruction to the second control part when the interval between the reception of printing data is longer than the reference value. The second control part continuously rotates the potosensitive drum for a definite period after the completion of the printing of a page according to the first printing starting instruction, and stops the photosensitive drum rotation immediately after the completion of the printing of the page according to the second printing starting instruction. Thus, when the period of sending the printing data from the outside device and the interval between the receptions of the data are long, the wasteful rotation of the photosensitive drum after the completion of the printing of the page can be reduced, and its level of exhaustion with respect to the printing number can be lowered.

Further, the flow in of the conductive particles 22 into the space parts between the adjacent electrode terminals 16 is prevented. The connection of a panel and the circuit board by the electrode terminals of the fine pitch is made possible with the high reliability.

Filed: 1990-11-26
Abstract: PURPOSE:To eliminate fix-positioned sound transfer induced by a differential phase of a reproduction signal during traveling at thrice speed in forward and reverse directions by using an addition/selection circuit. CONSTITUTION:A signal recorded on a tape is input into a decode/error correction circuit 3 by way of a recording head 1. The decode/error correction circuit 3 outputs data to an addition/selection circuit 7.
