Title: Structure of bga connection
Inventor: SOEJIMA KOJI
IPC: H01L21/60
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent brake of solder at a BGA connected part caused by repeated stresses in thermal history, even when a module board and a circuit board have different thermal expansions in a structure of BGA connection for connecting the circuit board and a component larger than an LSI or the module board. SOLUTION: Solder 3 has an inner plastic ball 7, and a gap is generated at an interface between the ball 7 and a nickel film 5 as a lower solder layer. The solder 3 has a drum-shaped cross section. In this case, strain applied on the solder is absorbed by a gap 6, and the stress is attenuated. Since the solder 3 has the drum-shaped cross section, concentration of stress is hard to occur. When electrodes 2A and 2B in a module board and a circuit board are made to be in a plane shape, elongated and projected in a direction of tensile stress, a life of the connection part corresponding to repeated changes in temperature is not affected by variation in the amount of the solder 3.

Title: Signal transmission system

IPC: H03M7/30
Filed: 1983-08-16
Abstract: PURPOSE:To transmit precisely PCM code data with a small number of bits by restricting the change of a scale value in case of the scale value is reduced to restrain the probability of occurrence of overflow error to a sufficiently low value. CONSTITUTION:In a scale determining circuit 15, a scale detecting part 15a detects an original scale value based on the maximum data of absolute values from one-block components of input differential pulse code modulation DPCM code data. A scale value setting part 15b compares the original scale value detected by the part 15a with the preceding set scale value; and if they are equal to each other or the input original scale value is larger, the input scale value is outputted as the set scale value as it is. But, if the input original scale value is smaller, (the preceding set scale value)-1 is outputted as the set scale value independently of the original scale value. A scale value holding part 15c holds the set scale value as the preceding value for the next scale value determination in the setting part 15b.

IPC: G06F13/00
Filed: 1982-08-27
Abstract: PURPOSE:To enable the judgement of the abnormality in the transfer of data between plural microcomputers, by investigating whether diagnosis data is fed within a prescribed time or not. CONSTITUTION:A microcomputer A performs real time processing such as inputting of the number of copying sheets, checking of whether a copying button is pushed or not and displaying of the number of copying sheets. A microcomputer B controls the sequence of the stage for electrophotographic copying. When there is a request REQ for data transfer from the microcomputer A and the microcomputer B is ready to accept the data transfer, said microcomputer informs to the microcomputer A of the acceptable REQ.E and in synchronizing with a shift clock SCK, the data is serially transferred from an output port SO to an input SI between the microcomputers A and B. When the operator pushes a diagnosis switch SW1, the diagnosis data is fed and after a prescribed time, the diagnosis data is compared with the diagnosis data stored beforehand and if both data are not identical, the computer judges that the transfer is anomalous and lights an alarm lamp PL.

Abstract: PROBLEM TO BE SOLVED: To immediately and accurately inspect a printed material by a method wherein an image on an object to be inspected is imaged to be stored, a mask is set to a boundary section of a reference image stored beforehand, an operation for subtracting the image to be inspected from the reference image is executed and a reference image masking operation is applied to an inspection signal, then the quality is judged based on the remaining signal. SOLUTION: A control section 5 comprises an image operation unit 53, RAMs 54, 55 and a CPU 58. The CPU executes the controlling by using the RAM 44 along a control program stored in the RAM 54. A mask is formed with respect to an image boundary section of a reference image to be stored as a reference image mask. A printed image of an object to be inspected is imaged to be stored and an inspection image is stored. After both of the images are aligned, a subtracting operation is executed and an addition defect detecting signal is generated from the subtracted result. Next, a masking operation using the reference image mask is applied thereto and a noise at the image boundary section is erased. A noise due to a shift is erased by masking on it and a stuck foreign material is detected by not masking on it, thereby raising the detection accuracy of a defective object.
