Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a face-regulated electrolytic copper foil having extremely good properties, a method for producing it, and its use. SOLUTION: In the method for producing face-regulated electrolytic copper foil, electrolytic copper foil having a shiny face and a mat face in which the average surface roughness lies in the range of 2.5 to 10 μm is subjected to mechanical polishing at least one time so as to control the average surface roughness of the mat face to 1.5 to 3.0 μm, and, after that, the mechanically polished mat face is selectively subjected to chemical polishing so as to control the average surface roughness to 0.8 to 2.5 μm. Moreover, the face-regulated electrolytic copper foil is produced by such method. PCB and multilayer laminated PCB use this face-regulated electrolytic copper foil.  The mat face is subjected to the mechanical polishing and is next subjected to the chemical polishing, so that the face-regulated electrolytic copper foil having extremely good properties can be obtd., where PCB denotes an abbreviation of printed circuit board.

Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To provide a quantum well optical modulator which is increased in a foundation absorption end shift by widening a quantum well width without lowering extinction intensity and is capable of making low-voltage operation and a module for optical communication and optical communication system using the same. SOLUTION: A quantum well structure is formed by using a material (group III-V compd.) having a large dielectric constant for quantum well layers 11 and using a material (group II-VI compd.) having a small dielectric constant, such as ZeSe, for barrier layers 12. The ratio of the dielectric constants of the quantum well layers 11 and the barrier layers 12 is made larger than 1.5 to intensify the Coulomb interaction of the electrons and holes in the quantum well and to intensify the coupling energy of excitons and vibrator intensity. The operating voltage is lowered by making the quantum well width when the coupling energy of the excitons is maintained constant is maintained constant larger than that of the conventional materials.

Title: Control circuit of protecting device
Inventor: KANO SHUNSUKE
IPC: G05B9/03
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To properly output a control signal even at the time of abnormality in the operation of a microprocessor. SOLUTION: The output of CPU 1 is connected to a first switch 3. CPU 1 reads a count value written in a common memory 8 by CPU 5 and judges that the operation of CPU 5 becomes abnormal unless the count value is changed. When the abnormality of CPU 5 is detected, CPU 1 outputs a reset signal and permits CPU 5 to be a reset state. Since the output of CPU 5 is set to be a high level at the time of resetting, a high level signal is given to the control terminal of the first switch and the first switch becomes an ON-state. Thus, the output signal of CPU 1 is outputted to an outside with the switch 3.

Title: Anode structure of magnetron
Inventor: ENDO KAZUNORI
IPC: H01J23/20
Filed: 1987-10-07
Abstract: PURPOSE:To eliminate an adverse effect of variance in a tube characteristic caused with molten brazing material dripping down long on the side surface of an anode vane by providing the anode vane with a groove for guiding the brazing material in. CONSTITUTION:An anode vane 9c to be brazed to one end of a microwave guide-out conductor 5 is provided with brazing material guiding grooves 11a, 11b having the length from the point where an anode cylinder 1 is to be brazed to the point where said conductor 5 is to be brazed. This causes excess portion of molten brazing material to enter the brazing material inducing grooves 11a, 11b and prevents said material from dripping below the grooves when soldering the anode vane 9c to the anode cylinder 1 by heating and melting a brazing material 16 of a high melting point. Further, as the molten brazing material which enters the grooves flows in the grooves and reaches a joint section where the microwave guide-out conductor is joined, it becomes unnecessary to supply the brazing material in advance to the joint section where the anode vane 9a and the microwave guide-out conductor 5 are joined.

Title: Antiseismic tester for side wall of building
Inventor: HONDA HIDEYUKI
IPC: G01M7/02
Filed: 1988-10-06
Abstract: PURPOSE:To enable various antiseismic tests for a side wall of a building by arranging a plurality of slabs vertically separated or linked together in parallel with a main frame comprising a roughly rectangular prism-shaped frame body. CONSTITUTION:Slabs 52 corresponding to respective layer are supported horizontally on a main frame 51 in such manner as to be allowed to play. The slabs 52 are so arranged to vibrate longitudinally or horizontally independent of one another and moved using a hydraulic cylinder. A side wall of a building as object to be tested is mounted on the surface of slabs 52. For example, when a test is conducted against a force applied horizontally viewed on the paper, the slabs 52 positioned at a higher level are moved to the right or left and those 52 positioned at a lower level moved to the left or right. At this point, as displacement of the slabs are controlled by a computer according to layers, this test can be realized with a shorter stroke of the cylinder and a smaller applied force, thereby enabling various vibration tests for the side wall of the building.
