Abstract: A semiconductor chip (5) is mounted and fixed onto a 
stem (1). A wiring substrate (7) is mounted and fixed 
around said semiconductor chip (5) on said stem (1). A 
number of through-holes (1b, 7a) are provided so as to 
penetrate the stem and the wiring substrate, and a number 
of lead-pins (3) are inserted into said respective 
through-holes to extrude from the lower surface of said 
stem (1). Said semiconductor chip and said wiring 
substrate are covered by and hermetically sealed to 
metallic shell (10). The input-output terminals of the 
electric circuits formed on the semiconductor chip(5) are 
connected respectively to said lead-pins (3) through 
wiring layer formed on said wiring substrate (7). In 
such construction, it is possible to obtain a positive 
hermetic sealing which is adaptable to multi-pin 
construction, thereby to reduce the manufacturing cost of 
semiconductor packages.
Patent EP-0261696-A3 (EP)
IPC: G01T1/164
Filed: 1984-02-27
Abstract: A method is provided for processing pulses, 
caused by a radioactive source and produced by an imaging 
radiation detector, by applying the technique of weighted 
acquisition for forming an image. An image weight function is 
formed corresponding to the source radiation, said function 
being dependent on the energy of said pulses in consideration 
of both the energy dependent signal-to-noise ratios of said 
pulses and the energy dependent modulation transfer functions 
of said pulses. Thereby a weighting pulse is obtained for each 
of said pulses, the particular value of said weighting pulse 
determined by the observed energy of said pulse. Said 
weighting pulses are then accumulated as said image.

Title: Picture motion measurement
IPC: H04N7/32
Filed: 1989-09-01
Abstract: A method of picture motion measurement in which two pictures 
are correlated to determine correlation as a function of 
displacement to determine peak correlation values corresponding 
to motion vectors. In the method a maximum sample point (P) 
associated with a peak in a correlation surface is located and 
a second sample point (D) of those immediately surrounding said 
point (P) selected having the steepest gradient with respect to 
the said point (P). The difference (d1) in magnitude between 
these points is determined as is the corresponding difference 
(d2) between the said point (P) and a point (H) colinear 
therewith. A comparison of these differences (d1 and d2) is used 
to determine the location of the peak to an accuracy better than 
the interval between adjacent sample points.
Patent EP-0330309-A3 (EP)
IPC: H05K13/06
Filed: 1989-01-24
Abstract: The apparatus randomly inserts crimped wire 
lead (22) (Fig. 1) one at a time into a multicircuit 
connector (12). The apparatus includes a pair of 
elongate insertion jaws (350, 352) (Figs. 21 through 
25) for longitudinally surrounding and gripping a 
crimp terminated wire lead (22). The insertion jaws 
are actuable by a gripper control (128) between a 
first open position (Fig. 26) a second intermediate 
gripping position (Fig. 27) wherein the jaws are 
axially slidable along the gripped wire lead and a 
third closed position wherein the jaws firmly grip 
the lead in a non-slidable manner. The jaws (350, 
352) and their gripper control (128) are mounted for 
axial movement along the wire lead into the insertion 
station (42). A drive (130, 132) for the jaws moves 
the jaws in their intermediate wire gripping position 
along the wire segment until a proximity sensor (58) 
(Fig. 3) senses the tips of the jaws abutting the 
rear end of the crimp terminal (26). In response 
to the sensor (58) the gripper control (128) changes 
the jaws to their closed position on the wire prior 
to insertion. The insertion jaws (350, 352) push 
on the rear end of the terminal (26) and do not rely 
 
 
on the column strength of the wire during insertion 
of the lead (22) into the connector housing cavity 
(20). A programmable housing index module (68) is 
movable along X, Y and Z axes and a terminal guide 
jaw assembly (56) are provided for use with the 
insertion jaws to provide an apparatus capable of 
randomly inserting the leads (22) into the housing 
cavities (20) in any order.
