Title: Liquid-crystal display device
Inventor: YASUDA SHIGERU
IPC: H05K3/36
Filed: 1985-03-20
Abstract: PURPOSE:To reduce contact resistance and to improve adhesive strength by arranging a flexible wiring board which has two divided connection terminals on one terminal of a transparent electrode for external connection across an anisotropic conductive adhesive, and making an electric connection by thermocompression bonding. CONSTITUTION:Connection terminals 5 of the flexible wiring board 4 are position- matched on the top surface of the transparent electrode 2 for external connection and then pressed against a heat plate, so that they are joined with the anisotropic conductive adhesive 3 by fusion. In this case, almost all the anisotropic conductive adhesive 3 right under the two divided connection terminals is removed to a part where no pressure is applied, i.e. except to the connection terminals 5 and to a recessed part formed of the two divided connection terminals 5. Consequently, conductive particles of the anisotropic adhesive 3 contact one another closely in the gap among the connection terminals 5 and transparent electrode 2 for external connection to decrease the contact resistance. At the same time, no pressure is applied directly to the anisotropic conductive adhesive 3 right under the recessed part of the connection terminals 5, so there is almost no flow of the adhesive, which is confined to the recessed part, thereby maintaining the adhesive strength by forming a reservoir for the adhesive.

Abstract: PURPOSE:To improve the picture quality by providing an output of a digital picture signal converted from a picture output voltage read by plural photoelectric conversion elements while correcting dispersion in each element or the like based on simulated white reference data and black reference data so as to obtain accurate white reference data. CONSTITUTION:An output voltage (b) of a picture read by the close contact type image sensor 11 comprising plural optical-to-electrical transducer elements is converted by an A/D converter 14 which provides a digital input picture signal N. White black reference data W, B obtained in advance from a reference original are stored in white black reference data line buffers 16, 17, and a CPU 13 obtains simulated white level reference data WA by adding a predetermined adder to the signal N. Bit correction and picture processing processors 15, 18 correct the signal N based on the data WA and B to correct the dispersion in the characteristic of each element of the sensor 11 and the lightness of each lens. Thus, accurate white level reference data are obtained to improve the picture quality.

Abstract: PURPOSE:To reproduce a clock signal which is necessary for the decoding encoded information stably and securely, by negatively feeding back the ringing output of a quartz oscillator to the input side of the quartz oscillator successively to the transmission period of the encoded information signal. CONSTITUTION:Data packet transmitted intermittently is led to a ringing circuit 1 composed of a quartz oscillator to apply a clock synchronizing signal, composed of a clock line signal in the data packet, to the ringing circuit 1 intermittently. Thus ringing which continues stably at least in each data packet period is caused and the ringing output is led out as a reproduced clock signal. At the same time, the ringing output is fed back negatively to the input side of the ringing circuit through a feedback circuit 2 to gradually suppress the continuous ringing until it stops.

Abstract: PURPOSE: To form the joint of flat pipes of heat exchangers, etc. in a good fitting state through sure brazing by forming a cylindrical part and a drawn part in the end part of a flat pipe, fitting a tubular body clad with a brazing filler metal onto  the drawn part and joining these by brazing in a furnace.  
     CONSTITUTION: A cylindrical part 3a, a drawn part 3b and an approximately horizontal step part 3b are formed in the end part of a flat tubular body 1 made of Al. A tubular body 1 clad with a brazing filler material 2 is fitted onto this drawn part 3b and its end face is abutted on the step part 3c. When these are loaded into a furnace and are heated, the brazing filler metal 2 on the surface of the tubular body 1 melts and flows into the contact part of both. At this time, the step part 3c blocks the flow of the brazing filler metal 2 and therefore the metal 2 forms a fillet 2c in the step part 3b, whereby the sure brazing is accomplished. By this method, fitting of the flat pipe to other tubular body is made easy, and the joint which is surely brazed with less possibility of loosening of the joint is formed.
