Patent JP-S61188836-A (JP)
Title: Color picture tube
Inventor: INOUE MASACHIKA
IPC: H01J29/07
Filed: 1985-02-15
Abstract: PURPOSE:To prevent deterioration of color purity due to welding by limiting the welding point with the shadowmask frame within two for one short side and two diagonal sections. CONSTITUTION:The shadowmask bodies 7-9 is made of low thermal expansion metal while the frame is made of common iron material where the shadowmask is welded to the inside of frame at three points on the long side while two points on the short side. Upon function of color picture tube, the frame will thermally expand to apply tensile force in the arrow direction through the welded points thus to vary the landing position of electron beam onto the fluorescent material, but since the welding points on short side and diagonal section is limited, outward tensile force of the shadowmask near the horizontal axis is weakened. Consequently, the difference of the variation of landing position of electron beam in horizontal direction near the horizontal axis and the diagonal axis is reduced resulting in cancellation of the deterioration of the color purality.

Title: Liquid crystal display device
Inventor: MURAMATSU NAGAYOSHI
IPC: G02F1/1345
Filed: 1990-02-06
Abstract: PURPOSE:To easily and accurately align a liq. crystal display device (LCD) and COF semiconductor device and to enable perfect automation by separately forming aligning patterns for the LCD and COF. CONSTITUTION:A graduated LCD aligning pattern 5 is formed at the outermost part of the input terminal 3 of LCD 1 and a COF aligning pattern 6 is formed at the outermost part of the output terminal 4 of COF 2. Since the patterns 5, 6 are used, the accuracy of a alignment of the terminals 3, 4 is enhanced in all the transverse, longitudinal and turning directions. Even when the aligning positions of the LCD 1 and the COF 2 are varied, accurate alignment is carried out only by making the aligning position of the pattern 6 coincide with the desired one of the graduations of the pattern 5. Simple automatic assembling is enabled.

Filed: 1990-02-08
Abstract: PURPOSE:To suppress the abnormal end of communication caused by the exhaustion of recording sheets at a minimum by detecting the remaining amount of recording materials based on a call incoming from a network and controlling timing for incoming call response based on the detected remaining amount. CONSTITUTION:At respective FAX 100-1 and 100-2, various information elements such as a transmission ability information element, low-order layer matching information element, high-order layer matching information element, incoming number information element and incoming sub address information element, etc., are taken out and it is judged whether a response is made to the incoming call or not.

Continuously, response delay time tn is decided corresponding to the detected remaining amount Ln of the recording sheets. The respective FAX 100-1 and 100-2 generate waiting for the decided tn time, and after the lapse of the tn time, the incoming call response is displayed to a communication control part 6. Thus, the incoming call can be made preferential to the FAX equipped with the large remaining amount of recording sheets.

Title: Thermal head
Inventor: KANEMURA MASAJI
IPC: B41J2/345
Filed: 1984-02-17
Abstract: PURPOSE:To obtain a thermal head which performs a recording clearly with a higher energy without the use of a special heating body by connecting a part of adjacent heat generating means to each other. CONSTITUTION:An insulation section 5 electrically separates individual electrodes 4 completely while a part of resistance elements 6 are separated. Hence, a part on the common electrode 3 side of resistance elements 6 are connected to adjacent ones 6. In a thermal head 1 thus arranged, as a voltage is applied to one resistance element 6, a part of current flowing through the resistance element 6 runs into the adjacent one 6 through a connection part. This diffused the current and prevents the resistance element 6 from being broken regardless of a high energy applied to one resistance element 6. The heat generation range of the resistance element 6 to which the voltage is applied can be broadened to make the recording clear.

Title: Method and device for recovering cfcs
Inventor: UTSUKI KOICHI
IPC: F25B45/00
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to recover CFCs remaining in a collecting device virtually completely by sucking out CFCs from inside the collecting device by keeping a compressor and a vacuum pump simultaneously in action throughout the change of pressure of CFCs in the collecting device from high pressure, through atmospheric pressure, and to a vacuum. SOLUTION: By controlling a pressure regulation 10 a passage for CFCs from an oil tank 6a to a vacuum pump 11 is shut off and the CFCs is sucked out by a compressor 17 alone until the pressure of the CFCs changes from a high pressure to the atmospheric pressure. At the atmospheric pressure the pressure regulator 10 is turned back and the passage for CFCs is opened on the one hand and on the other hand the vacuum pump 11 is started and made to continue the suction jointly with the compressor 17 in action until the pressure falls from the atmospheric pressure to a vacuum. This method enables drawing out the CFCs or oil-containing CFCs in the collecting device virtually completely to a state of vacuum and recovering the contents.

Title: Operation system for high frequency bridge inverter
Inventor: HOSHI TOSHIHIKO
IPC: H02M7/48
Filed: 1978-03-10
Abstract: PURPOSE: To make an increase of the current capable of flowing in the thyristor, by means of time-division operating and not simultaneously firing the thyristors in a relation of parallel connection.  
     CONSTITUTION: In a time chart, as shown in the drawing, of the time-division operation system, of a plurality of thyristors, that are in a parallel relation for each conduction mode, only one thyristor is in a state of conduction, with the remaining thyristors being in a relation not in a state of conduction. Accordingly, no consideration is necessary at all for current unbalance, with the thyristor made usable fully at the rating. In this way, the constitution of two-parallel connection, if operated by the time-division system, makes a level of the current, capable of flowing in the thyristor, almost double as compared with that not of the parallel constitution.
