IPC: B21D28/04
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent defects of a product by performing the punching after confirming that a material to be punched is surely brought into contact with a reference surface of a press die through presence/absence of the electric conduction. SOLUTION: When a downward pin 3 to be lowered together with a stripper plate 1 presses a slide member 4 to transversely move the slide member 4 to the side of a reference surface setting member 7, a material 6 is pressed against the reference surface of the reference surface setting member 7, and the reference surface setting member 7 is pressed in the transverse direction to be abutted on a stopper 8 and positioned at the normal position. In the positioning condition, a spring 9 for the reference surface is compressed by being pressed by the reference surface setting member 7 and the elastic repulsive force is accumulated. Alter these actions, the small voltage (5-15V) is applied between the stopper 8 and the material 6 to check presence/absence of the electric conduction.  When the electric conduction is confirmed, the stripper plate 1 is further pressed down to achieve the prescribed punching. Otherwise, the press action is immediately stopped.

Title: Information recording medium
Inventor: NAKAMURA NAOMASA
IPC: G11B7/243
Filed: 1986-11-28
Abstract: PURPOSE:To improve durability and corrosion resistance by consisting a recording layer of a compsn. consisting of an indium-antimony alloy as a base material and contg. 5-30atom% oxygen. CONSTITUTION:The recording layer 2 is constituted of the compsn. consisting of the indium-antimony alloy as the base material and contg. 5-30atom% oxygen. An InSb alloy is liable to oxidize and In2O3 and Sb2O3 are easily formed merely by introducing gaseous oxygen thereto at the time of forming the recording layer. The InSb alloy particles are, therefore, held in the state being embedded in the In2O3 and Sb2O3 by using the InSb alloy as the base phase and adding 5-30atom% oxygen thereto. Said In2O3 and Sb2O3 are chemically stable even at a high temp. and do not deteriorate at the temp. at which the InSb alloy is heat-treated. The durability and corrosion resistance of the recording layer are thereby improved and the recorded information is maintained stably for a long period of time.

IPC: G03G15/04
Filed: 1988-11-09
Abstract: PURPOSE:To prevent an exposure part of a document from floating by providing a document path in an exposure part in such a way that it is deviated either above or below a line connecting document paths which are placed before and after the document path. CONSTITUTION:The document path 171 in the exposure part D is provided in such a way that it is deviated either above or below the line connecting the document paths 73 and 74 which are placed before and after the document path 171. When a document OD goes into the document path 171 in the exposure part from the document path 73 ahead of the exposure part, the leading edge of the document OD is bent compulsorily to a bent side because the document path is bent upward or downward. Therefore, the document OD is pressed to either an upper or lower bent guide surface formed by a platen glass 12 and guides 171a - 171c and goes along the guide surface. Thus the document is prevented from floating from the guide surface.

Filed: 1986-11-28
Abstract: PURPOSE:To prevent repeated stress from exerting a specific relief valve, by changing the set pressures for at least two of a plurality of relief valves, including an actuated relief valve each time when one of the relief valve is actuated. CONSTITUTION:There are provided a set pressure value memory device 10 which stores therein set pressure values corresponding to relief valves 3 with respect to relief valve actuating logic 5, and a set pressure exchanger 11 for exchanging set pressure corresponding to the relief valves 3 each time when arbitrary one of them is operated.

Title: Decarburization distribution-detecting method for metal wire surface
Inventor: OISHI YUKIHIRO
IPC: B21C51/00
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To detect a decarburization distribution of a metal wire surface by measuring in succession a variation of a load distribution laid on a die with load cells arranged at the die exit side of a metal wire drawing. SOLUTION: At the exit side of an extracting steel wire 4 in a die box 1, a plural number of load cells 5 are arranged equally dispersed around the die 2 hole as the center. These load cells 5 measure the extracting force of the steel wire 4 at the time of its drawing along with the passage of time and in succession. Since the extracting force, decarburization volume (decarburization layer thickness) and surface hardness of the steel wire 4 are mutually related each other between/among them, distribution of decarburization layer in the longitudinal direction and circumferential direction can be detected from the variation of the extracting force.  Thereby, this method enables not only to eliminate a complexity of measuring the thickness of the decarburization layer by a texture observation of the section of the steel wire 1, but also to grasp the variation of decarburization layer thickness in a longitudinal direction, which is conventionally difficult.

Abstract: PURPOSE:To stabilize and extend the life of discharge display operation by partially eliminating a dielectric layer outside a discharge area on an electrode so that an electricity conducting metallic protection layer is partially exposed to a discharge gas. CONSTITUTION:After forming an electrode 23 on a panel substrate 21, the electrode surface including the side surface of the electrode 23 is covered with a layer of a material having a strong effect as an electricity conducting metallic protection layer 24 and with its constituting atoms being hard to be moved by colliding ions, such as chromium layer, so that discharge characteristic relative to gas of a dielectric layer surface is not changed by the dispersion of electricity conducting substances such as copper. After that, an exposed electrode portion of the dielectric layer 25 is made with a large size as a leak passage for discharged charge. Neutralization of excessive charge and prevention of sputtering of an electrode material are made with this large charge leak space G and the electrode 23 with its surface covered with a fine-textured chromium layer 24. This makes it possible to discharge excessive charge on the dielectric layer associated with display discharge without the movement of the electrode material and to stabilize and extend the life of discharge display operation.
