Title: Electronic part package, printed wiring board and inspection of printed wiring board
Inventor: ICHIHARA YASUHIRO
IPC: H01L23/12
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To improve the attaching-work efficiency of an electronic part package and to prevent the peeling of the footprint in the circuit connecting part of the electronic part package in the ball grid array type electronic part package. SOLUTION: In a BGA package 10, a reinforcing pipe 15 is provided in the outer region of an ordinary circuit connecting bump 13. Therefore, even if shock is applied by the dropping of a printed wiring board 20 and the like during working, the reinforcing bump 15 and a reinforcing footprint 23, which are not related electrically with the circuit, absorb the shock at the outer part, which is most susceptible to the influence. Thus, the peeling and the cracks in the footprint 12 at the attaching part of the BGA package 10 and the footprint 22 on the side of the printed wiring board 20 can be prevented.

IPC: G06F15/02
Filed: 1980-05-07
Abstract: PURPOSE:To use the display function of a display equipment itself to confirm the capacity of a battery, by displaying the capacity of the battery by lighting a prescribed number of digits or digit positions on the display equipment. CONSTITUTION:The current of a battery B is input to a control circuit L through a DC/DC converter C and is further input to a printer P through a printer driving circuit A. Meanwhile, the signal from a keyboard K is subjected to operation and control by a circuit L, and the result is displayed on the display equipment and is printed as prescribed by a printer P. In this case, a timing pulse is generated by a timing pulse generator TPG and is sent to a pulse period detecting circuit DET. Consequently, if the capacity of a battery B is lowered, the period of the timing pulse formed by the TPG becomes long. This period is detected by the DET, and a small number of digits are lit on a display equipment D in accordance with the detection result. Meanwhile, if the capacity of the battery B is not lowered, a large number of digits are lit on the display equipment D.

Title: Thrust amplifying machine
Inventor: NITTA HIDEICHIRO
IPC: F16H35/00
Filed: 1990-03-13
Abstract: PURPOSE:To increase the thrust largely by driving a disk on which weight pieces are installed movable on a frame plate by a small motor, feeding its exciting current from a small generator on a main power shaft, and putting all bodies in a case and making into vacuum. CONSTITUTION:When disks 1 to 8 of a thrust amplifying body in a vacuum case are started to rotate at first respectively by a small motor 13 by feeding a current of a starter, weight pieces 12 of a disk 11 start to rotate together with the disk 11 because they are installed rotatable, and they rotate losing balance constantly because their installing positions are made asymmetrical. As a result, the rotation speed of the disk 11 generates a delay and a speedup, the unbalanced operation of the plural weight pieces 12 on one disk 11 are integrated to generate a thrust in a constant direction, rotates a rotary frame 9, transmits the output to an output shaft 10, and generates electric power. Since the power generated in such a way is excessive even though it is fed to the thrust amplifying body, the power supply from the starter is converted when several seconds pass from the starting of operation into a full self- sufficient power supply.

Title: Picture reader
Inventor: MATSUDA SHINYA
IPC: H04N1/107
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To correct the picture density in spite of the undulation of an original face by detecting the undulation of a read object face from a read picture when the original face is individually illuminated by using first and second illumination means and correcting a picture in accordance with a detection result on the read picture, which is obtained by the first illumination means. SOLUTION: A difference between a first illumination picture and a second illumination picture is obtained. Since an area becoming shadow at the wave part of the original face and near the finger of a user changes by the direction of illumination, the absolute value of the difference becomes not less than a prescribed value. Then, the appropriate threshold is set, the differential picture is threshold processed and the position of an undulation area in the read object face is detected. Then, the average of the first illumination picture and the second illumination picture is obtained. When 1/2 of the sum of photographing data D11 and D12 is obtained at every picture element, it becomes an almost similar value as a value when undulation does not exist.  Then, the image of the finger can be extracted from the read picture by setting the appropriate threshold approximated to the lower limit of base luminance and thresholding the average picture.

Natural picture data are stored as 8-bit pixel data and realize a cost reduction by reducing a memory size request on a buffer 14. A processor 10 can transfer such data at a speed which is increased against the preceding pixel data having a 24-bit width.
