Inventor: FURANTSU SHIYUTAIN
IPC: B22F5/08
Filed: 1989-11-01
Abstract: PURPOSE: To simultaneously and efficiently apply the deformation to the whole teeth surfaces in a clutch body at high precision by transferring the deformed force to the tooth surface of the powder metallurgy-made clutch body from an upper side punch gradually to on and after latter half of the engaging part of the upper side and a lower side punches of a pressing die. CONSTITUTION: Tooth surface setback part is worked along the tooth surface of an synchronizing ring of the clutch body obtd. with the powder metallurgy. At the time of forming this tooth surface setback part with plastic deformation, the synchronizing ring 7 is set to the lower side punch 2 of the die. Successively, a finger part 3 having a linear wall 4 with half or more height of the whole punching process 1 of the upper side punch 1 is guided with mechanical slippage into the space corresponding to the lower side punch 2 so as to insert into a guide bush through the gap of each tooth of the synchronizing ring 7.

Title: Pressure-sensitive adhesive sheet for treating semiconductor substrate
Inventor: MORITA TOSHIO
IPC: H01L21/683
Filed: 1986-11-27
Abstract: PURPOSE:To prevent the peeling of a semiconductor substrate during working while making a pressure-sensitive adhesive sheet easy to be peeled when peeling the pressure-sensitive adhesive sheet, and to obviate the generation of cracking by forming a large number of fine holes to the pressure-sensitive adhesive sheet for treating the semiconductor substrate. CONSTITUTION:The size of a fine hole 1 is brought to a diameter of approximately 0.5mm-2.0mm. A semiconductor substrate 3 is sucked directly to a suction base 4 not only by the adhesion of a sheet 2 but also through the fine holes 1. When the rear is ground, the substrate is sucked by force stronger than a conventional pressure-sensitive adhesive sheet is used during grinding, the time when the substrate is attracted to the suction base 4, thus extremely reducing the probability in which the semiconductor substrate is peeled during grinding. When the pressure-sensitive adhesive sheet is peeled after grinding, a contact area is made smaller than the conventional pressure-sensitive adhesive sheet, thus minimizing suction force only of the pressure-sensitive adhesive sheet, then resulting in easy peeling. Accordingly, probability in which cracking is generated when peeling the pressure-sensitive adhesive sheet is reduced.

Title: Facsimile equipment
Inventor: HASHIMOTO KENJI
IPC: H04N1/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To avoid the drop of direct current resistance at the time of releasing a line for a facsimile equipment. SOLUTION: A disconnection relay 102 is provided between a line 110 and a polarity inversion detection circuit 101. Also, each driving port of the disconnection relay 102 and a HOOK voltage feeding relay 107 is controlled as a shared port by a controlling part 200. And, when the shared ports are on, the HOOK voltage feeding relay 107 connects a TEL terminal 108 to a PCI and HOOK supply voltage part 106 and the disconnection relay 102 connects the line 110 to the polarity inversion detection circuit 101. On the other hand, when the shared ports are off, the HOOK voltage feeding relay 107 connects the TEL terminal 108 to the line 110 and the disconnection relay 102 disconnects the line 110 from the polarity inversion detection 101. This prevents the TEL terminal 108 and the polarity inversion detection circuit 101 from being simultaneously connected to the lines 110.
