Title: Magnetic panel
Inventor: SUZUKI SATORU
IPC: G09F9/37
Filed: 1986-04-30
Abstract: PURPOSE:To easily manufacture a magnetic panel without spoiling the sharpness of display by providing plural display chambers which narrow down from a display plate to a reverse plate and storage chambers which are linked with the display chambers through through holes and widen toward the reverse plate between the reverse plate and display plate. CONSTITUTION:When a magnet 11 is put close to or brought into contact with the display plat 2, magnetic force operates on magnetic particles 10, which are attracted toward the display plate 2 through the through holes 6 to stick on a magnetic thin film 7. At time time, the magnetic particles 10 are spherical and moved smoothly, a display of color based upon the color of the magnetic particles 10 is made on the display plate 2, and the magnet 11 is moved on the display plate 2 in the shape of an optical character of figure, so that the shape is displayed on the display plate 2. Liquid is charged in none of display chambers 8, so even if air enters a chamber, no air bubble is formed and a decrease in the sharpness of the display due to the mixture of air never decreases. Consequently, a process for removing the air entering the display chamber 8 is not necessary in the manufacture process and the manufacture of the device is facilitated.

Abstract: PROBLEM TO BE SOLVED: To make it possible to draw fine patterns at a high speed with a unifom definition by regulating the frequency of a clock signal to a specific value. SOLUTION: When the central angle 207 of a sectorial region inclusive of a region 202 is defined as θ(rad), the radius in the position of a laser spot for scanning as (r) and N as a positive value, the conditions under which dots line up in a diametral direction on at least segments 206 and 208 eventually suffice with that the length of the arc in the sectorial region of the central angle θ in any radial position has a difference by integer times the one dot length from that adjacent in the radial direction of a master disk and θWD =NLd is resulted.

Abstract: PURPOSE:To warn alarming the consuming of a dry battery by providing a circuit means to turn OFF a decimal point of a display tube when a warning is given against the consuming of a dry battery for compensation for power failure. CONSTITUTION:When the potential 3 is higher than the sum of a Zener voltage Vr of a Zener diode 6 and the potential VBE between the base and emitter of a transistor 4b, a transistor 4a is energized to supply a power +B of a power source or V to a segment serving as decimal point 1a of a display tube 1 to turn ON the decimal point 1a. In other words, when the voltage of a dry battery 3 is represented by VB, the turning ON is subject to the condition of VB>=VF+ VBE. As the dry battery is being consumed, the condition shifts to VB<VF+ VBE, where the base current fails to flow to a transistor 4b, turning OFF the decimal point 1a without energization.

Abstract: PURPOSE: To stabilize discharging property of liquid drops at all times without forced cooling and to record high quality images at a high speed by a method wherein half pillow type bubbles are generated positively, spherical bubbles are restrained from generation and an electricity-heat convertor is driven.  
     CONSTITUTION: Heat is generated by impressing electric signals on an electricity- heat convertor 15 and the temperature T of a heating surface 16 is raised. When it reaches a temperature Tth at which a spherical bubble B b  aapears, the spherical bubble B b  is generated and grows at an area As. When the temperature T rises further and exceeds the area A, a half pew-row bubble a used for discharging drops of liquid appears and grows. The bubble B a  grows up to a specific volume in a moment in such a shape as the heating surface 16 is covered, while the bubble B b  has such a spherical shape as it comes in contact with one point on the heating surface 16 and so its growing speed is slow and irregular. Therefore, the electrical signal or a voltage value is set so that the time Δt 1  required for passing through the area As becomes shorter like a curve Ca.
