Title: Toroidal inductor
Inventor: HONDA SHOZO
IPC: H01F27/32
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To reduce a leakage magnetic flux as much as possible. SOLUTION: A toroidal core 3 is housed in resin cases 1 and 2, and a conductor 4 is wound around this. Then, the resin cases 1 and 2 are formed by using Mn/Zn ferrite powder with high relative permeability as the dopant materials, and the resin cases 1 and 2 are provided with recessed and projection parts 5, in which the depth of the recessed part is made almost the same as the diameter of the conductor 4 for guiding the coil of the conductor 4 on the surface. The resin cases 1 and 2 are formed by using the magnetic powder with high relative permeability so that the leakage magnetic flux can be reduced, and the conductor is wound along the recessed and projection parts 5 formed on the resin cases 1 and 2, so that fluctuation in the way of winding the conductor can be restrained, and non-directional characteristics can be obtained from the uniformity.  Also, even if small leakages of magnetic flux are generated, since it is induced on the projection part of the recessed and projection part 5, the leakage magnetic flux can be reduced.

IPC: H04L69/14
Filed: 1988-12-16
Abstract: PURPOSE: To scan a plurality of transmission line within a shortest time by connecting a scanning means through a line interface coupler(LIC) having wired addresses. CONSTITUTION: A line adapator 1 is formed by a microprocessor 16 for executing a micro-code stored in a micro-code memory 17 and scanning logic 10 expressed by a front end scanner(FES) 10. Data exchange between an LIC 20 and a scanning means is executed through a multiplexed circuit 14 and a series link 12. In addition to data exchange on series lines 22, 24, each LIC 20 receives suitable time applied by the scanning means on a line 25. Consequently only an LIC 20 having a practically activated line is scanned at a specific moment and the scanning is executed in accordance with priority allowed to be optionally selected by an operator.

Title: J lead package
Inventor: FUKUDA KOICHI
IPC: H05K3/34
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a J lead package of a structure, in which a solder wicking phenomenon is less likely to occur in a soldering step. SOLUTION: A J lead L10 has a thickness of 0.4 mm in its upper part and has a thickness of 0.2 mm in its lower end part. The lead L10 has a width of 0.7 mm in its upper part and 0.4 mm in its lower part. The part of the lead having a thickness of 0.4 mm nearly coincides with the part thereof having a width of 0. 7 mm. In the lead L10 of this structure, when the lead is exposed to a vapor atmosphere having a temperature of 215 deg.C, the temperature of the lower part of the lead having a small heat capacity increases toward a vapor temperature more quickly than that of the upper part having a large heat capacity. Solder melted on a conductor of a printed circuit board becomes wet at the lower part of the lead L10 and stays there. Thereby it can be avoided that in several seconds after melting of the solder paste on the conductor, the solder at the lower part of the lead L10 is wicked toward the upper part thereof.

Abstract: PURPOSE: To easily make a multi-colored display with a small number of planes of a bit map memory by supplying all bits, read out of the bit map memory, to a look-up table. CONSTITUTION: All bits read out corresponding to the number of planes constituting bit map memories 10-12 are sent out to 1st-3rd look-up tables 14-16 in parallel, and luminance levels of red, blue, and green are read out of addresses indicated by all the bits.
