Title: Condition setting circuit for dc arc welding machine
Inventor: MIZUNO MASANORI
IPC: B23K9/073
Filed: 1980-12-11
Abstract: PURPOSE: To prevent the generation of welding defects and element failure in the event of switch contact defect by using a toggle switch having 3 positions as an output control element of welding conditions, and constituting only one of condition setting without going through the switch.  
     CONSTITUTION: A commercially marketed inexpensive toggle switch 21 of 3 positions is used, and when it is set in the position B, the output of a reference electric power source 1 is inputted only to the 3rd condition setter 5. Next, when the switch 21 is set in the position A, the power source output is inputted to the 1st condition setter 3 and the 1st phase inverter 22. At this time, the output of the power source 1 is directly inputted to the setter 5 at all times and therefore the output of the setter 5 goes zero. When the switch 21 is set in the position C, the output of the setter 5 goes zero as well and only the output of the 2nd condition setter 4 is produced. In this way, the outputs of the setters 3, 4, 5 are inputted to a control circuit 6, and the welding current conforms to the conditions of the respective setters 3W5.

Abstract: PURPOSE:To obtain a cheap masking lamination material by laminating through extrusion laminate a transparent synthetic resin film layer and heat adhesive synthetic resin film layer on an opacifying layer. CONSTITUTION:An opacifying lamination material is constituted such that a transparent synthetic resin film layer B and heat adhesive synthetic resin film layer C are laminated on an opacifying layer A through extrusion lamination. The opacifying layer A serves to opacify printing or writing and, for instance, paper or synthetic resin film or the like is made a base material, and one given opacifying properties by use of an aluminum foil or evaporated layer or the like is used. Especially, an opacifying layer arranged with a synthetic resin layer as its surface layer is preferable in view of the fact that it has an excellent waterproof property. As the transparent synthetic resin film layer B, a rear material of the opacifying layer A and synthetic resin with an excellent mold release property are employed. It is preferred to use, for example, polyethylene, polypropylene, polyester or any of those with which a separative addition agent is blended or the like. For the heat adhesive synthetic resin film layer C, it is necessary to have an adhesive force larger than the adhesive force of the transparent synthetic resin film layer B and, for example, it is preferred to use ethylene-vinyl acetate copolymer, ethylene-acrylic ester copolymer and any of those with which an addition agent is blended thereto, or the like.

Title: Method for inspecting liquid crystal panel
Inventor: TAWATARI HIROHITO
IPC: G02F1/13
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To eliminate a line drop-out, to make display images uniform and to eliminate line defects by using a contactor consisting of a resin which is stuck with metallic foil and has elasticity as the contactor to a display electrode. SOLUTION: The contactor 1 is formed by using chloroprene rubber having the elasticity having hardness of about 60. The metallic foil 10, such as, for example, aluminum, is stuck to the periphery of the contactor 1. The metallic foil 10 breaks the oxidized film on the surface of a display electrode 2 and the contact under a uniform pressure is made possibleby the elasticity of the resin in the lower part of the metallic foil 10. In addition, the hardness of the metallic foil 10 is lower than the hardness of the display electrode 2 and, therefore, the flawing to the display electrode 2 does not occur. As a result, there is no line drop-out on the screen of the liquid crystal panel and the display image may be made uniform and the occurrence of the line defect may be averted when the images are displayed on the liquid crystal panel for the purpose of inspection. The exact inspection of the operating state is thus made possible.

IPC: G06F3/02
Filed: 1984-08-24
Abstract: PURPOSE:To reduce the quantity of error record by noticing that the uniformity of a unique index is preserved even though one of double keys is remained, therefore only the head one of double keys is validated unlike a conventional case when all double keys are regarded as errors. CONSTITUTION:For instance, an error check processing part detects that a key ''2'' is double in rows of input order numbers 2 and 9 together with a key ''3'' double in rows of input order numbers 6 and 7 with Six1 respectively. Under such conditions, the flag of the head one of the double keys is set at ''1'' with the flag of the later key set at ''0'' respectively. These flags are stored to an error information able. Then each row of a table which is sorted again with the input order numbers is read out for check of flags in order to decide an improper record. Then an improper record is decided when the record having only a single key of flag ''0'' is detected.

IPC: H01L27/144
Filed: 1983-09-26
Abstract: PURPOSE:To facilitate the formation of a planar state by forming a field effect transistor to completely surround a photodetector, thereby eliminating an electrically insulating layer. CONSTITUTION:A resistor 16 is connected to a P type electrode of a photodetector 14, and a resistor 17 is connected to a drain electrode of a field effect transistor 15. An incident light signal is incident through the P type semiconductor layer of the photodetector 14 to a P-N junction, and converted into an electric signal. This signal flows through the resistor 15 to an external circuit. In this case, a potential gradient is produced corresponding to the signal at both ends of the resistor 16. The variation in the gate potential of the transistor 15 based on the potential gradient causes a variation in the drain current. Accordingly, the amplified electric signal is produced to external terminals 18, 19 as the potential gradient produced at both ends of the resistor 17 connected to the drain.
