Title: Ic card
Inventor: NAGAHAMA MASANORI
IPC: B42D15/10
Filed: 1990-11-28
Abstract: PURPOSE:To prevent the break of an IC caused by a static electricity and the break of data stored in a memory IC by a method wherein a top panel and a rear panel have an integral structure, a GND connecting projected part is provided on the panel, and a substrate GND is connected to the panel. CONSTITUTION:A top and rear integral panel 1 is formed by a single metallic plate with a U-shaped structure. This structure ensures an electric conduction between the top side and rear side of the panel. A GND connecting projected part 2 is connected to a negative electrode 4. Since this negative electrode 4 is connected to a substrate GND, the electric potential of the top and rear integral panel 1 is kept at the same electric potential as the substrate GND. At this time, if a static electricity is applied to the top and rear integral panel 1, electric charges are not stored in the panel, and an electric current generated by the static electricity does not flow to an internal IC but flows to the GND. In this manner, the break of the IC and the break of data stored in a memory IC can be prevented.

Abstract: PURPOSE:To make elements forming ink drops dense by a method wherein the present device is constructed of members including a plate-like member made of a material liable to suffer mechanical strain in an electric field and interdigital electrodes provided on one side of the plate-like member, and ink is brought into contact with the surface of the other side of the plate-like member that is opposite to the side on which the interdigital electrodes are provided. CONSTITUTION:Interdigital electrodes 2 made of a material including gold as a principal ingredient are provided in a shape of concentrical circle on a plate-like member made of sliced mono-crystal lithium niobate, a material liable to suffer mechanical strain with an electric field, with polishing applied, and the above-mentioned interdigital electrodes are connected to an electric source for driving. Walls 4 are provided to the other side of the plate-like member 1 on which the interdigital electrodes are provided so that the walls come between the interdigital electrodes 2. Areas encircled with the walls 4 and the plate-like member 1 are filled with ink 5 that is supplied from an ink supplying member. With high-frequency or pulsating current applied to the interdigital electrodes 2 from the electric source for driving, elastic wave is induced to occur to the plate-like member 1. The elastic wave propagates to the ink 5, letting ink drops 6 make optional flying from the free surface of the ink 5. Thereby two-dimensional arrangement of the interdigital electrodes 2 becomes possible and elements of ink drops can be made highly dense.

Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To not only supply/intercept negative pressure but control it based on the set value according to the necessary condition at each time by connecting a means supplying/intercepting suction air to a control circuit. SOLUTION: A restriction 43 is set on a position so that optimum negative pressure is applied to a slit 30 at each time through a control circuit 21, based on the yarn parameter corresponding to a cop 2 and the process step at each time. On a partial closed position of the restriction 43, a half of an opening 44 is covered. By changing the opening cross section, a suction flow is suitably intensified, and negative pressure applied to the opening 44 is intensified. The negative pressure is transmitted into a pipe 29, and negative pressure at the slit 30 is intensified. Particularly, it is selected when the end part of a released underwinding yarn is sucked into the pipe 29. The larger the opening 44 is closed by the restriction 43, the larger a suction flow applied into the pipe 29 in its turn generated negative pressure therein becomes.

Title: Tracking device for optical disk player
Inventor: KAWAKAMI SATOSHI
IPC: G11B7/095
Filed: 1991-11-25
Abstract: PURPOSE:To perform stable tracking servo. CONSTITUTION:The phase difference between two diagonal sums of light receiving faces 1a to 1d of a photodetector is denoted as a time difference error signal, and the difference signal between two areas divided by a boundary line along the track of an optical disk is denoted as a push-pull error, and these signals are mixed. Four divided light receiving faces 1a to 1d are divided into two by a boundary line (x) orthogonal to a boundary line (y) parallel with the tangential direction of the track of a disk, and the phase difference between respective detection outputs S1+S2 and S3+S4 of one divided receiving faces 1a and 1b and the other divided light receiving faces 1c and 1d is detected by a phase comparator 27, and the attenuating operation of attenuators 11 and 26 is controlled in accordance with this phase difference. Thus, stable tracking servo of high gain is performed because the time difference error signal is emphasized if the push-pull error signal is not sufficiently obtained because of the pit depth approximating lambda/4.

In a cold-rolled steel plate, the rolling direction is set in the circumferential (rθ) direction of the tube. The work in which a projected part is large in size, and the thickness reduction of an apex part can be suppressed, is realized.
