Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To enable the common use of a joint member sealing jig for seal test if an inside diameter of a pipe passage of a joint member is the same by tightening a nut screw-fitted on a bolt and expanding an outside diameter of an elastic body provided between seat plates. SOLUTION: To apply a joint member sealing jig on a joint member 6, a sealing jig is inserted through an opening 6a side to which a hose of the joint member 6 to be used in a test is connected, and a nut 5 is tightened for a bolt 4. Then, an outside diameter of an elastic body 1 compressed by seat plates 2, 2 is expanded to be larger than the initial outside diameter so that a pipe passage 6b of the joint member 6 can be sealed. The joint member 6 in which the pipe passage 6b is sealed is formed as a connection body between a hose and the joint member 6 by fitting the hose externally through the opening 6a side for a seal test, and then aged treatment is applied to it in a constant temperature bath for the purpose of pretreatment of the seal test to conduct the seal test.  Consequently, if an inside diameter of the pipe passage of the joint member is the same, the joint member can be used in common irrespective of its shape.

Filed: 1994-12-13
Abstract: PURPOSE: To narrow the dynamic range of an AGC by varying the terminal resistance value of a circuit for amplifying the output of a magnetic head, thereby decreasing the high-frequency noises of inner peripheral side signals and unifying the output amplitude over the entire area of a recording region. CONSTITUTION: The signal outputted from the magnetic head 4 by a CDR recording system is amplified by R/Wic5 of an amplifier circuit and is inputted to a terminal resistance setting circuit 1. This circuit 1 consists of a parallel circuit of a resistor 2, a resistor 3 (resistor 2 > resistor 3) and switches 7, 8 and delivers the output signals to a signal processing circuit 9. A head position output circuit 6 transmits a logic signal to the circuit 1 which in turn controls the switching of the switches 7, 8 in correspondence to the disk region to be reproduced. As a result, the amplification gain characteristic of R/Wic is settable to meet the output signal characteristics from the respective recording zones in a CDR recording system and, therefore, the design of the optimum reproducing system without having an excess gain and excess band is possible.
