Patent JP-H07141417-A (JP)
Title: Net list conversion system
Inventor: NAKAMURA SUSUMU
IPC: G06F17/50
Filed: 1993-11-18
Abstract: PURPOSE:To easily cope with the condition change of a manufacture process by using an N-to-M conversion table, coping with a case where the correspondence relation of the symbols of a circuit symbol part and the symbols of a substrate symbol part is many-to-many and narrowing down candidates in a symbol conversion part. CONSTITUTION:The N-to-M conversion table 38 allows description coping with many-to-many since the symbols of the circuit symbol part 12 and the symbols of the substrate symbol part 22 are not in one-to-one correspondence but generally in many-to-many correspondence. The symbol conversion part 32 performs the conversion of the symbols of the circuit symbol part and the substrate symbol part and is provided with a function for narrowing down the plural candidates to one when the plural candidates are recommended in the N-to-M table 38. For a net conversion part 34 and a sign conversion part 36, since the information of a circuit design part 10 and the information of a substrate design part 20 is in the one-to-one correspondence, coping is performed without preparing the complicated N-to-M conversion table. Thus, an operation for converting the circuit data of the circuit design part 10 into the circuit data of the substrate design part 20 is smoothly performed.

Filed: 1992-10-01
Abstract: PURPOSE:To display the supply of a power source to a light emitting element by switching a switch circuit corresponding to the switching of a display element and the light emitting element, and driving an LED. CONSTITUTION:The display device of a picture and a spatial light transmitter are incorporated in a view finder optical system 5 of a video camera, and they are arranged by rotating a lever 34. A lever 34b is rotated to an arrow right and left direction with a fixed edge 34a as a center. When the lever 34b is rotated to the arrow left direction, the leaf part of a switch 35a is pressed down, terminals 35c and 35d are short-circuited, and the terminal 35c is grounded. Then, when a transistor Tr1 is turned on, and a transistor Tr2 is turned off, the power source is supplied to a driving circuit 32 of a display element 4, and the power source is not supplied to a driving circuit 33. When the lever 34b is rotated to the arrow right direction, a switch 35a is allowed to rise, the power source is supplied to the circuit 33, and the power source is not supplied to the circuit 32. Thus, when a light emitting element 13 is present on an optical axis, the power source is supplied to the circuit 33, the LED is driven, and the emission is displayed by the display element 4.

Title: Twisted string, using yarn made of synthetic resin and increased in elastic force and its production
Inventor: AKAMA TAKEO
IPC: D02G3/32
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To simply and economically produce a twisted string using a yarn made of a synthetic resin by forming the twisted string having a force (return couple of forces) to return to the original state against a twisting force, inherent and retained in the yarn made of the synthetic resin and increasing an elastic force or increasing the repulsive force. SOLUTION: This twisted string increased in elastic force is obtained by using a yarn 1, made of a synthetic resin and prepared by rotating the yarn 1 made of a synthetic resin in the right or the left direction with the axial center direction as the center, applying a twisting force thereto, making a force (return couple of forces) to return to the original state inherent in the yarn 1 made of the synthetic resin, forming a two-yarn twisted string 6 while making the return couple of forces inherent and retained therein, fixing the two-yarn twisted string 6 with a nipping means, preventing the runback of the twist or hardening the surface of the two-yarn twisted string 6 with an adhesive and providing a strengthened two-yarn twisted string 6 having the return couple of forces,  kept inherent and retained in the yarn 1 made of the synthetic resin or preparing the two strengthened two-yarn twisted strings 6, twisting the two strengthened two-yarn twisted strings 6, providing a four-yarn twisted string, hardening the surfaces thereof with an adhesive applied to the surface and affording a strengthened four-yarn twisted string having the return couple of forces, kept inherent and retained in the yarn 1 made of the synthetic resin.

Title: Magnetic head and its production
Inventor: MUKAIDE NORIAKI
IPC: G11B5/31
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To suppress the negative edges generated by gradually degrading the magnetic permeability at the end on the side opposite to the magnetic gap layer of magnetic cores the futherer from the magnetic gap layer with respect to the lamination direction of the magnetic gap layer. SOLUTION: The magnetic permeability of the first magnetic core 2 and the second magnetic core 5 is gradually deteriorated toward the end edge 5a of the magnetic core 5 near the end (dotted line part) of the magnetic core 5 on the side opposite to the magnetic gap layer 4 consisting of SiO2 , etc., which is a gap material layer. A nitrogen compsn. increases simply with an increase in a nitrogen partial pressure when the magnetic cores are produced by changing the nitrogen partial pressure at the time of sputtering. The nitrogen compsn. decreases when the sputtering electric power under the same nitrogen partial pressure increases. Such decrease arises from the increase in the sputtered atoms of Fe and Ta and the relative decrease in the atom number ratio of N to the Fe and the Ta when the sputtering electric power increases.  The adjustment of the magnetic permeability is made possible by controlling the sputtered atom number of the Fa and the Ta constant, thereby controlling the nitrogen compsn. of the sputtered films.

A single → twin atmospheric pressure correction factor is decreasingly set according to reduction in atmospheric pressure by a linear function expression by atmospheric pressure, and a single → twin switching judging value is set by correcting the single → twin switching judging basic value by atmospheric pressure by this correction factor.
