Patent JP-H087778-A (JP)
Title: Cathode-ray tube
Inventor: HOSOYA NOBUHIKO
IPC: H01J29/50
Filed: 1994-06-27
Abstract: PURPOSE:To improve focusing performance over the whole screen by forming a four-pole magnetic field surrounding electron beams on the shield cup inner wall of an electron gun, and applying a tensile force or compressive force to each electron beam using Lorentz's force. CONSTITUTION:As circumferentially stretching, two permanent magnets 2a, 2b are installed in a part of the inner wall of the shield cup 1 of each electron gun of cathode-ray tube in such an arrangement as intersecting each color electron beam passing through apertures 1a-1c. These magnets 2a, 2b form a four-polar magnetic field with the right above as N-pole, left above as S-pole, right below as S-pole, and left below as N-pole when the cup 1 is viewed from the fluorescent screen side wherein the beam arranged direction is assumed to be horizontal. With this four-pole magnetic field, Lorentz's force applied to electron beams becomes tensile forces V, V' in the vertical direction and compressive forces H, H' in the horizontal direction to the side electron beams, which permits correcting the under-focus in the vertical direction and also over-focus in the direction to the left and right. This enhances the focusing characteristics over the whole screen, and a high quality image can be reproduced.

Title: Sound volume and sound quality adjusting device
Inventor: SASAKI YOSHIO
IPC: H03G3/34
Filed: 1988-06-14
Abstract: PURPOSE:To cause the difference of output levels before and after switching to be practically zero and to prevent a discontinuous part from generation, which becomes noise on auditory feeling, by generating a signal, which changes over an analog switch group, at the almost zero cross point of a reproducing signal from a source. CONSTITUTION:The reproducing signal from a source 1 and a standby signal (STB) from a control part 5 are inputted to a strobe generating part 11 and a strobe signal ST is generated at the zero cross point of the reproducing signal. For example, a strobe generating part 114 is composed of a two-input AND circuit. Then, the output of an EX-OR circuit 112a is connected to one input and an output Q of an RS-FF part 113 is connected to the other input respectively. When the both inputs go to an H level by the operation of an AND circuit 114, the output goes to be the H level and the strobe signal (ST) is generated. Accordingly, the discontinuous part before and after the changing-over of the analog switch group can be reduced infinitely and the noise on the auditory feeling can be erased.

Title: Overload checking device for sequencer
Inventor: KAWABATA MUNEHIRO
IPC: G05B23/02
Filed: 1982-08-20
Abstract: PURPOSE:To check easily whether a sequencer is overloaded or not by comparing the actual load on the sequencer with a reference voltage obtained by the voltage division of real loads of a reference resistance. CONSTITUTION:The reference resistance 20 generates a measurement voltage V2 by the voltage division of real loads 8 and 9 of the sequencer 1. Then, the output transistor 4 of the sequencer 1 is turned off and a switch 14 is closed. A measurement voltage V2 generated at this time is compared by a comparator 18 with the reference voltage V1 of a reference voltage generator 19 which discriminates overloading. When V1<V2, a display device 17 turns on. Therefore, a user judges whether the sequencer is overloaded or not on the display device 17. Thus, whether the sequencer is overloaded or not is checked easily.

Title: Waterproofing method for exposed concrete surface
Inventor: KITAMURA TORU
IPC: B05D7/00
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To enhance the waterproof effect and weatherability of a concrete surface by evenly coating an exposed concrete surface with a minutely elastic waterproof material, a waterproof film of which after drying and film formation exhibits a specific elongation percentage, and patterning the concrete surface by tapping the same by means of a needle felt at a final step of finish coating with a weather resistant resin paint. SOLUTION: An exposed concrete surface is evenly coated with a minutely elastic waterproof material containing a resin including a synthetic resin emulsion as a main component. The minutely elastic waterproof material forms, after drying and film formation, a 1-mm thick waterproof film having an elongation percentage of 30% or more at 20 deg.C, and therefore it can exhibit sufficient waterproof effect. Further, the waterproof material is strong in adhesive power, and therefore a coating step of a primcoating material can be omitted. Thereafter, finish coating is carried out for a plurality of number of times by using a finish paint containing a weather resistant resin as a main component, a pigment, and various solvents, to thereby obtain a dried film thickness of, e.g. 10 μm or more. At a final step, the surface is patterned by tapping the same by means of a needle felt impregnated with the finish paint, to thereby obtain a surface extremely similar to the exposed concrete surface. Thus, the waterproof effect of the concrete surface per se can be enhanced, and the weatherability and life of the concrete can be improved.
