Title: Paste-like solder
Inventor: NAOI MASAYA
IPC: H05K3/34
Filed: 1988-04-20
Abstract: PURPOSE:To eradicate the Manhattan phenomenon of a face packaging part by using the paste-like solder composed of two kinds of solder grains of different m.p. CONSTITUTION:A paste-like solder 10 is composed by mixing at specified amt. the low m.p. solder grain 10a having the m.p. difference of about >=20-30 deg.C and a high m.p. solder grain 10b. A face packaging part 1 is lightly joined to conductive layers 6, 7 by the low m.p. solder grain 10a first. In this case there is a difference of elevation in an atmospheric temp. and at the time when the part of the conductive layer 6 side is higher only the low m.p. solder grain 10a there is melted. Due to the surface tension generated at that time being small and no moment enough to rise the conductive layer 7 of one part being unobtainable a Manhattan phenomenon is not caused. With further rise of the atm. temp. the high m.p. solder grain 10b is also melted and completely fixed without causing the Manhattan phenomenon via the same trend process as the low m.p. solder grain 10a. Consequently, the Manhattan phenomenon of the face packaging part can surely be eradicated.

Title: Transmission buffer controller
Inventor: HAYASHI YASUHITO
IPC: H04L12/801
Filed: 1991-04-04
Abstract: PURPOSE:To attain the transmission of a packet to a network by taking priority of the packet after overflow into account when the transmission buffer overflows. CONSTITUTION:When a transmission buffer section 40 overflows, the transmission buffet section 40 sends an overflow detection signal 80 to a packet abort/ extraction section 20. The packet abort/extraction section 20 decides whether or not the priority of a packet with priority is higher than a threshold level set to a threshold level setting section received from a priority packet generating section 10 after the reception of the detection signal in response to the detection signal 80 and extracts a packet with a higher priority than the threshold level and sends the result to a packet replacement section 50. The packet replacement section 50 references transmission buffer management information to select a storage location of a packet whose priority is lower than that of the received packet and whose storage priority is low and replaces the received packet with the selected packet of the storage location.

Title: Semiconductor device
Inventor: BABA TOSHIO
IPC: H01L21/338
Filed: 1982-06-08
Abstract: PURPOSE:To obtain a FET whose drain current to gate voltage varies in step form, by utilizing that the degree of expansion of a depletion layer differs with the unevenness of the impurity density. CONSTITUTION:N-GaAs 21a of approx. 5X10<18>cm<-3> is laminated approx. 50Angstrom , and N-GaAs 22a of approx. 1X10<18>cm<-3> approx. 200Angstrom  on a semi-insulating GaAs substrate and grown alternately three times, N-GaAs 22a of 5X10<17>cm<-3> is superposed, and then a Schottky gate electrode 3 and ohmic source and drain electrodes 5 and 6 are added. When the gate voltage VG equals VO, the end of the depletion layer 4 is in the layer 21c, and the drain current ID flows. When the VG is increased on the negative side and the end of the depletin layer enters the N<-> layer 22b, the depletion layer enlarges, and accordingly the ID varies largely. Further, when it enters the N<+> layer 21b, the ID variation is decreased, and then the displacing gate voltage thereof is VT2. Moreover, the increase of the VG enables the VT2 to appear, and the access of the end of the depletion layer to the substrate makes the ID equal O. When the VG is increased on the positive side, likewise VT3 appears. Thus, an FET having various kinds of threshold values is obtained.

IPC: G01B11/02
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a measuring device that performs a three-dimensional measurement at low cost and high speed. SOLUTION: A level of measuring objective solder 9 is obliquely imaged by a camera 2 from the oblique direction. Then, it is illuminated by a lighting system 1 from the oblique direction at the opposite side to this camera 2, and it is made discriminable so as to make a ridgeline of the level of the solder 9 become higher in luminance than that of a hillside of the solder 9. An image processor 5 discriminates the ridgeline from the solder picture imaged by the camera 2, and using the lower side position information of a land image of a printed circuit board of a sample in advance, the height of the solder 9 is found out by geometrical calculation from the height information on an oblique image surface due to the ridgeline and the lower side.  In addition, this picture image processor 5, in the case where a measuring objective solder image is in a position where a focal point of the oblique image surface is shifted to some extent, the solder height found out so far is compensated by multiplying an inverse number of both enlargement and reduction ratios of size at the position concerned so far calculated and stored by a comparison between two land images of the printed circuit board being presampled in a measuring objective data memory 4.
