Title: Flexible printed circuit board
Inventor: AIKAWA SATOSHI
IPC: H05K1/00
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a flexible printed circuit board on which a marking pattern can be formed without spending costs and a space too much by a method in which a mark such as a character, a symbol or the like is formed by an opening which is formed in a photosensitive cover lay film. SOLUTION: Marks 7, 8 are polar patterns formed by openings in a cover lay film. Then marks 7 are 'K' marks which express cathodes of chip diodes 3, and the marks 8 are '+' marks which express positive sides of chip tantalum capacitors 2. Then, the marks which are easy to recognize are formed in such a way that a surface treatment whose color tone is different from that of the cover lay film or a copper foil such as a gold plating operation, a solder plating operation or the like is executed because a pure copper foil is difficult to recognize. Then, since the marks are formed by the cover lay film, they can be arranged without depending on a wiring pattern. As a result, it is not required to lay out the width of the wiring pattern unreasonably, and the safe and sure wiring pattern can be formed.

Title: Scramble method in catv system
Inventor: IDENO AKIRA
IPC: H04N7/167
Filed: 1984-01-24
Abstract: PURPOSE:To produce scramble effect without operating an image signal itself by switching the number of a video signal relative to plural carrier waves so that respective picture sources are on different carrier waves for every one field. CONSTITUTION:An originating side sends out picture sources up to #1-#N1 as N number of TVRF signals by N number of TV modulators 2. Where a switch 3 synchronized for every vertical synchronizing period of TV, switches the picture sources according to its assignment relative to channels ch-1,...ch-N. While, switching information of the switch 3 is taken out as a data signal by a data converter 4, is mixed with signals by a mixer 5 in a TVR and is sent out to each terminal. A receiving side changes carrier wave of each picture and changes a VT voltage of an oscillating circuit 7 in a converter 6 synchronized in a step form for every vertical synchronizing period to convert the picture into an IF signal.

Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To improve detection sensitivity of partial discharge by enabling discriminating electromagnetic waves generated by partial discharge from external noise, in an insulation abnormality diagnosing equipment of an electric apparatus. SOLUTION: A judging part 27 detects external noise by using a noise antenna 14, selects a specific number of frequencies wherein external noise is low, in the diagnosis frequency band of 300-1000MHz, and determines the selected frequencies as the diagnosis frequencies. In the course of diagnosis process, the judging part 27 uses detected signals of the diagnosis frequencies out of the frequencies, which are detected by an abnormal electromagnetic wave detecting antenna 13, and judges whether insulation abnormality exists. As a result, insulation abnormality can be diagnosed by using only the electromagnetic waves caused by a partial discharge.

IPC: G06K9/20
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a copying machine capable of quickly discriminating a failure of a device and, accurately locating its position. SOLUTION: After an image of an original is read out, its checked whether the character direction of image data read out from the original is discriminated or not (S1), and when the character direction is discriminated, it is considered as normal. When the character direction is not discriminated, a specific pattern previously drawn in the vicinity of the original is read out (S2) to execute character direction discriminating processing. When the character direction is discriminated, it is determined that the device is operating normally (S4) while the original is defective. When the character direction is not discriminated again, only the character direction of a built-in pattern is discriminated (S6, S7). When the direction is discriminated, the it is determined that the failure is generated in a reading system (S8), and when the direction is not discriminated yet, the failure is determined as one generated in a control system (S9).
