Title: Position confirmation of seal tester
Inventor: FUKUDA YASUHIRO
IPC: G01M3/16
Filed: 1978-05-16
Abstract: PURPOSE: To detect the seam in a manner to detect the variation in a magnetic resistance moving in a pipe and to confirm the measuring position of a seal tester with respect to the seam accurately and promptly by providing such a detecting element at the center of the seal tester as can detect the magnetic resistance due to the seam.  
     CONSTITUTION: Steel pipes 10 and 10' constituting a pipe passage is equipped with a sleeve 11 on the outer circummference of the portioncorresponding to a seam 12, the sealed condition of which is maintained by welded portions 13 and 13'. At the center between rubber elements 2 and 2' of a seal tester 1 for testing the seal of the seam 12, a detecting element 7 is arranged to detect the variation in the magnetic resistance due to the seam 12. The element 7 is connected with the body 8 of the detector through a cord 9. The position, where the magnetic resistance is varied, is detected by the element 7, while moving the tester 1 in the pipe, and the position detected is deemed as the measured position of the tester 1. As a result, even if the pipe is made of a bent steel pipe, it is possible to accurately and promptly confirm the positional relationship between the seam 12 and the tester 1.

Title: Production of pearl like gloss pigment especially having blue color
Inventor: BUERUNAA OSUTERUTAAKU
IPC: C09C1/00
Filed: 1989-03-13
Abstract: PURPOSE: To produce the particularly bluish pearl luster pigment with good productivity by subjecting mica pigment coated with TiO 2  to specific thickness to ammonia reduction.  
     CONSTITUTION: The bluish pearl luster pigment is produced by subjecting the mica pigment coated with titanium bioxide to ammonia reduction at a high temperature. Here, the mica pigment in use has the TiO 2  coating of 50-100 or 300-340 nm in optical layer thickness and the process using ammonia is carried out at 750-850°C to hold the pigment in a continuous motion state throughout the reduction. It is important to use dry ammonia and the reduction is hardly performed with wet ammonium. Therefore, ammonium with remaining humidity of ≤0.02 mgH 2 O/1NH 3  is preferably used. The reduction time depends upon the transformation and temperature where TiO 2  in the coating is present in the form of rutile and/or anatase.

Title: Optical receiving amplifier
Inventor: SAITOU JIYUUMEI
IPC: H04B17/00
Filed: 1980-04-30
Abstract: PURPOSE:To cut off microplasma noise by discriminating a no-signal input with simple constitution by separately detecting the microplasma noise generated by an avalanche diode when no signal arrives and a circuit output signal when an input signal exists. CONSTITUTION:The output of amplifier 5 is supplied to separating circuit 8 composed of HPF and signal cutting-off circuit 9 which interrupts a signal path. The output of circuit 8 is supplied to discriminating circuit 11, controlling circuit 9, via circuit detector 10. Consequently, a circuit output signal when avalanche diode 1 has an input signal is separated from the noise of diode 1 generated when no signal arrives, and the difference in this output level is detected 10 and compared with the reference signal of discriminating circuit 11 to discriminate a no-signal input. This simple constitution discriminates the no-signal input and cuts off microplasma noise appearing at the output of the amplifying circuit.

IPC: A43B23/07
Filed: 1995-02-23
Abstract: PURPOSE: To maintain the warmth retaining and heat insulating properties, and make the texture pleasant with air refreshed by knitting a pre-dyed thread to form a coil-shaped loop, and standing it on the pile fabric, which internally covers the backing sewn to a shape of foot. CONSTITUTION: A shape of foot is cut out and formed by intermediately putting base cloth 4 and heat insulating flexible synthetic resin foam 3 between the backing 1 and right side 6.
