Title: Drawing block means having a dice box capable of automatic positioning
Inventor: ROBAATO JIEI ROO
IPC: B21C1/22
Filed: 1990-09-18
Abstract: PURPOSE: To make it possible to allow a die box to naturally follow up an exact angle position and to prevent the vibration or oscillation about axes by installing a device for naturally rotating the die box to an exact drawing position, then clamping the die box to a position which may be continuously regulated. CONSTITUTION: A cylinder 38 for positioning in a horizontal direction and a stationary cylinder 39 in a perpendicular direction are released of driving force when the action of drawing is started and just before the die box 13 moves upward. The die box about both axes is moved by a piston in the contraction state to the cylinders. Since the die box is freely movable, a tube 1 emerging from a die 35 is lowered on a downward direction so as to extend straightforward to a position on a capstan by which spiral taking-up is executed. When the die box 13 arrives at the drawing position, the stationary cylinder 39 of the perpendicular direction and a caliper brake 41 are immediately driven to prevent the rotation of the die box 13 about both axes.

Filed: 1986-10-21
Abstract: PURPOSE:To prevent an optical disk medium and an optical head from sticking dust by providing an optical disk medium and a dustproof filter of non-contact with the medium at the outer peripheral parts of the optical disk medium in a case. CONSTITUTION:An optical disk cartridge 11 stores the optical disk medium 3 in the case 1. The dustproof filter 2 is provided so as not to contact with the medium 3 at the outer peripheral part of the optical disk medium 3, so that a space is formed at the near side to the case 1 of the filter 2 to reduce flow resistance. The cartridge 11 shown in the figure is loaded into an optical disk device and the optical disk medium 3 is fixed to a spindle 4 to be turned at high speed. By this rotation, air near the surface of the optical disk medium 3 is blown off to the outer peripheral part to pass through the dustproof filter toward the side wall of the case 1 and to form air circulation 8. A dusty air is supplied from around the center of the spindle 4 as well, but the air inside the case 1 is filtrated through the dustproof filter 2 to remove dust.

Abstract: PURPOSE:To insure an adequate range of combustion from the viewpoint of primary air ratio and volumetric capacity of combustion chamber and achieve excellent radiation efficiency by placing a pair of combustion chamber walls, each with a plurality of flame holes, in opposition to each other at a specified distance therebetween and in such a manner as to have paired flame holes opposed and bring them into alignment and by forming a combustion chamber defined by the combustion chamber walls, side plates, and a bottom plate. CONSTITUTION:A combustion chamber 14 is formed by a pair of combustion chamber walls 11, 11, a bottom plate 12, and a pair of side plates 13, 13. A sheathed heater 20 is turned on, and when a vaporizing cylinder 19 has been heated up, fuel 23 is ejected from a fuel nozzle 22. The fuel 23 vaporizes as it impinges against the vaporizing cylinder 19, and after mixing with primary air 24, which has been sent simultaneously, the fuel passes through a throat 17 and forms a uniform fuel-air mixture 25. After passing through a mixing chamber 16, the fuel-air mixture 25 is fed into the combustion chamber 14 through flame holes 15, 15 which are opposed to each other two by two coaxially, ignited, and forms opposed flames 26. The opposed flames 26 lose speed where they collide into each other in the combustion chamber 14 so that the resulting slack in flow serves to stabilize the flames.

Title: Method and device for controlling traffic
Inventor: IDE SHOTARO
IPC: H04L12/28
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To reduce required memory capacity by expressing a minimum cell interval among traffic monitor parameters and a minimum cell interval among parameters to be used for finding the output time of cells through a traffic shaper in one common parameter. SOLUTION: A minimum cell interval T and a minimum cell interval T to be used for the shaper are expressed in the common parameter and after a violation is discriminated, CDV are immediately reduced. When real arrival time Ta of a cell is later than time based on theoretical rules, this cell is judged as a suitable cell and after TAT is changed to current time, the TAT is updated. When this arrival time is ealier, the difference between the theoretical cell arrival time TAT and the cell arrival time ta is compared with the level relation of a CDV allowable value 7τu and it is discriminated whether this cell is suitable or not. When the TAT-ta is larger than the τu, this cell is abandoned as a non-suitable cell but when the TAT-ta is smaller than the τu, shaping is performed as the suitable cell within an allowable range.  Thus, the number of parameters to be stored can be reduced by two.

A metal 4 such as Pt possibly serving as electrode is immersed into the diluted sulfuric acid in the container 3 facing the construction 1 and is connected to the anode of the power source. Then, when current flows, an electrolysis takes place to generate hydrogen around the construction 1. A part of the hydrogen generated is absorbed by the construction 1 to cause a hydrogen embrittlement at the desired point 2. Thus, a repeated load can be applied at the desired point 2 of the construction 1 to generate and progress a cracking due to fatigue as desired starting from the slit part.
