Title: Plane fluorescent tube and display device using it
Inventor: HIRAYAMA RYUICHI
IPC: H04N5/66
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To miniaturize a whole device used as a back light by shortening a discharge part of a facing electrode to which high voltage pulse is not applied than a discharge part of an electrode to which high voltage pulse is applied. SOLUTION: This plane fluorescent tube 21 has discharge electrodes 22a, 22b formed in hollow cathode structure of a U-shaped or V-shaped cross section, and so as to have discharge parts of different length. The length J1 of a discharge part of the discharge electrode 22a to which high voltage pulse is not applied is remarkably shortened than the length J2 of a discharge part of the discharge electrode 22b. Uniform surface discharge is kept and at the same time the plane fluorescent tube 21 is made small, and can especially accommodate for a liquid crystal display panel mounted by a COG method, whose right and left are asymmetrical.  Since the cross sections of the discharge electrodes 22a, 22b are formed like this, even if the discharge part to which high voltage pulse is not applied is shortened, uniform surface discharge can be kept by sufficiently increasing the surface area of the electrodes.

IPC: A61M1/14
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a blood pressure monitoring device capable of obtaining a high blood pressure monitoring precision without giving a burden on an organism. SOLUTION: A low cuff pressure control starting means 66 starts a low cuff pressure control means 68 when a change value ΔD of a normalized pulse wave surface area SF computed by a pulse wave area change value computing means 64 exceeds a preset determination reference value DO. This low cuff pressure control means 68 increases pressing pressure of a cuff 10 to a specified low pressure value P1 lower than an average blood pressure value BPMEAN of an organism.  A cuff pulse wave change rate computing means 72 computes a change rate θ of an amplitude Am of cuff pulse waves detected by a cuff pulse wave detection device 27 to change of the pressing pressure of the cuff 10 in the low cuff pressure control means 68, and a blood pressure value abnormality determination means 74 determines abnormality in a blood pressure value in the organism based on the change rate θ of the amplitude Am of the cuff pulse waves computed by the cuff pulse wave change rate computing means 72. Pressing frequency by the cuff 10 is thus reduced, and blood pressure can be monitored at a high precision compared to devices in which the low cuff pressure control means 68 is started at a specified period.

Filed: 1993-12-10
Abstract: PURPOSE:To prevent the occurrence of the fluctuation of tension and the fluctuation of a plate thickness caused by a disturbance, and to enable a stable flying rolled plate thickness changing by executing the flying hot rolled plate thickness changing by the correction of a roll speed, and controlling tension between stands with a drawing down operation. CONSTITUTION:When executing the flying hot rolled plate thickness changing of a material 3 to be rolled, the drawing down control of a roll and the timing of the change of a roll speed in each stand, are calculated by tracking at the change point of a plate thickness. And, simultaneously with the arrival of the change point of the plate thickness to each stand, the roll speed is corrected to a roll speed corresponding to the plate thickness of a succeeding material. At the same time, a drawing down position is corrected so that tension between stands, coincides with an target value to be determined by the unit cross-sectional area of the average thickness of a material between stands. Consequently, tension per unit cross-sectional area of the material between stands, can be controlled to be constant to the change of a roll speed, and stable hot rolling can be performed over the whole length of the material.
