Title: Chip-sized package
Inventor: NAKATANI NAOTO
IPC: H01L23/12
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce the difference between the coefficients of thermal expansion of a chip-sized package and a printed wiring board on which the package is mounted by increasing the coefficient of thermal expansion of the package as a whole, by firmly sandwiching the wafer at both lower and upper surfaces and fixing a resin having a larger coefficient of thermal expansion than a semiconductor wafer made of an epoxy resin, etc. SOLUTION: Two sheets 12 and 12' of copper foil having a larger coefficient of thermal expansion than an epoxy- or polyimide-based semiconductor wafer 1 has are respectively laminated upon the upper and lower surfaces of the wafer 1. Then pads 4 and 4' for solder bumps are formed by etching off unnecessary parts from the foil 12 and 12', and connection via holes 3 and 3' are formed through the foil 12' to the bonding pads 11 and 11' of the wafer 1. Thereafter, solder bumps 5 and 5' are respectively mounted on the pads 4 and 4' by electroless-plating the via holes 3 and 3' with copper for electrical connection and applying a solder resist 6. Therefore, the fracture of solder junctions can be prevented.

Title: Document preparation device
Inventor: ABE KENICHI
IPC: G09G5/24
Filed: 1987-09-16
Abstract: PURPOSE:To enable preparation of a document with characters of natural style arranged which is close to a handwritten document by setting an area which allows superimposition of a character frame over an individual character font and seeking an amount of character frame superimposition over adjoining characters. CONSTITUTION:Information on an area which allows superimposition of vertically adjoining characters is read from a storage part 5 for an area permitting superimposition by a decision part for an area permitting superimposition 6. Then it is required to obtain an amount of possible superimposition of character frames of upper over lower characters when a border line for an area permitting the superimposition of upper characters over lower characters and a border line for an area allowing the superimposition of lower characters over upper characters come into contact with each other. Next, the amount of character frame superimposition is obtained by multiplying the amount of superimposition of these character frames by a superimposition ratio specified by an operator. This is applied to all vertically adjoining characters, and the amount of character superimposition obtained in this way and each character font are read by a font compounding part 9 to produce an output image on an image memory. Thus an output image of superimposed character frames is produced.

Title: Apparatus and method for pattern inspection
Inventor: WAKINO TOMOO
IPC: G06T7/60
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method, for the inspection of a pattern, in which even abnormality of size can be recognized, irrespective of the problem of the number of measuring elements and in which the defect of a graphic to be inspected can be detected with high accuracy. SOLUTION: A small critical circle 51 and a large critical circle 52 are applied to a pattern image which is binary coded by reading the wiring pattern of a printed wiring board. At this time, when all pixels in a region 53 at the inside of the small critical circle 51 are 'dark', and when all pixels in a region 54 along the outside of the large critical circle 52 are 'bright', the dark pixels in the region 53 and dark pixels which are continued to them are recognized as a hole. When one among a condition at the inside of the small critical circle 51 and a condition at the outside of the large critical circle 52 is not satisfied, it will not be recognized as a hole.

Title: Digital demodulating device
Inventor: KATSUTA HIROTATSU
IPC: H04L27/32
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To provide a receiver for demodulating a wide band received signal with a ROM with a small capacity which can be loaded on a DSP. SOLUTION: A control circuit 7 detects the maximum value of channel signals outputted from low-pass filters 5a and 5b of a quadrature demodulator 10 from the sum of squares of co-phase components and quadrature components. When the number of quantization bits is converted into an n dynamic range, a DRC circuit 6 obtains a demodulator output signal normalized with the maximum value by a DRC circuit 6. Then, the normalized signal is multiplied by 1/2 of the n-th power of 2, and the figures below a decimal point are omitted so that a signal whose dynamic range is decreased can be obtained, and transmitted to a PM demodulating circuit 8. An ROM loaded on a present DSP copes with the arithmetic table of the PM demodulating circuit at that time.

Title: Home video camera
Inventor: YAMAMOTO AKIHIRO
IPC: H04N9/74
Filed: 1983-12-07
Abstract: PURPOSE:To convert the characters written on a subject into colored characters by discriminating the luminance signal level of the subject and using this discriminated signal to perform switching between the video and color character signals. CONSTITUTION:A gamma-corrected luminance signal YH supplied to a clamping circuit 15 from an input terminal 14 is calmped to the fixed voltage for its blanking level. The output of the circuit 15 is compared with the reference voltage by a voltage comparator 16. Then a pulse which is set at a high level at a low or high luminance part is produced. The output of the comparator 16 is supplied to a blanking mixing circuit 18. A character signal switching pulse thus produced is used to mix the character signal supplied through a character signal input terminal 20 with a video signal through a character signal adder circuit 11. The character signal supplied from the terminal 20 is converted into a color signal by superposing a chrominance carrier wave onto a certain DC level.

Filed: 1993-09-16
Abstract: PURPOSE:To prevent the burning of a coil even when a large current or a high voltage such as DC power source is carried. CONSTITUTION:When a voltage is applied to a voltage tripper 24, a movable core 23a is turned counterclockwise by the attracting action of a plunger 25, the interlocking shaft of an opening and closing mechanism is pressed in a tripping direction by the movable core 23, and a control axis is moved counterclockwise, whereby a movable contact base 7a is also similarly operated together with a movable contact base. Since a movable main circuit is thus tripped, and the contact between the movable contact base 7a and a fixed contact base 4a is opened, the current-carrying to a voltage tripping coil 28 is interrupted, and the burning of the coil 28 can be prevented.

Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of printing quality by making the fixed end of a printing hammer certain even if the spring constant of the printing hammer is raised due to speedup by providing a groove to the rear plate fixing the printing hammer on the side of the contact surface with a leaf spring of the rear plate. SOLUTION: A yoke base 3, a front yoke 4, a rear plate 9 and a leaf spring 5 storing printing energy as the bending of the spring are provided to a hammer mechanism part and a groove A is provided to the rear plate 9. The rear plate 9 is fixed to the leaf spring 5 as the contact surface with the spring on the side provided with the groove A of the rear plate 9. As a result, the leaf spring 5 does not come into contact with the whole of the rear plate 9 and the contact surfaces of both of them are made small. By this constitution, the warpage quantity of the leaf spring 5 becomes little and the leaf spring 5 is suppressed only at the part near to a fulcrum. Therefore, the fulcrum of the spring can be made constant even if the spring constant of a printing hammer is raised.  That is, by setting the fulcrum of the leaf spring 5 to the vicinity of the upper fulcrum of the contact part with the rear plate 9, the length of the spring is stabilized.
