Title: Method of reduction precipitation of metal ion
Inventor: ASANO SATOSHI
IPC: B01D11/04
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent mixing of impurity elements into the objective metals to be reduced, and to precipitate the objective metals to be reduced in high yield by allowing a reducing agent to react under the conditions of the presence of halide ions of a specified concn. in an aq. soln. SOLUTION: By this method, only the objective metals to be reduced are selectively reduced and precipitated while coprecipitation and coreduction of impurity elements are prevented by converting the impurity elements present together with the metal ions in the soln. into halide complexes so as to reduce the reduction potential. Practically, when the objective metal to be reduced is gold, the impurity element present is silver and the halide is chloride, the concn. of the chloride ion present in the liquid is increased so as to prevent both of precipitation of silver chloride and reduction of silver. This method can be also used for the reduction of other metal ions, and is effective for halides except chlorides. The concn. of the halide in the liquid is preferably 0.1 to 13 mol/l.

Title: Apparatus and method for detecting statement of virtue
Inventor: ISHIGURO AKIO
IPC: G01V5/00
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To simply and continuously detect the presence/absence of statements of virtues with avoiding direct touch of X rays to medical supplies, by projecting soft X rays only to one end of the statement in a box carried so that the one end of the statement faces opposite to a projection direction of the soft X rays. SOLUTION: A box 1 is transferred along a transfer line 5 to pass through a virtue statement-detecting apparatus comprising an X-ray generation device 6 and a detector 7. At this time, soft X rays are projected through a slit 8, and hits only one end of a virtue statement because of the slit 8 without directly hitting a drug. The soft X rays passes the box 1 while hitting the one end of the statement, and reaches the detector 7. The detector 7 detects one end of the statement in the box 1, thereby detecting the presence/absence of the statement. A detection state is image-processed by an image-processing apparatus 60, and the presence/absence of the statement is displayed on a screen. If the box 1 contains the statement, the box is introduced to a product pack station. Without the statement, the box is transferred by the transfer line 5 to a failure product place.

Title: Steel tube screw joint
Inventor: MATSUI HIROYUKI
IPC: F16L15/04
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide high galling resistance by forming a pin side seal face and a coupling side seal face into a conical face, and setting the seal taper angle defined as the angle between the bus and tube axis larger o the coupling side than on the pin side. SOLUTION: The seal taper angle αc on a coupling 2 side is set larger than the seal taper angle αp on a pin 1 side. When the coupling 2 is coupled with the pin 1 and fastened under the existence of a seal interference quantity 10, a displacement in the radial direction occurs to negate the seal interference quantity 10. Since αc >αp , a pin side seal section 4 having weak rigidity is shrunk in diameter, a coupling side seal section 5 having strong rigidity is slightly expanded in diameter, αp and αc are changed to the approaching side to each other, and a nearly ideal seal state is obtained that a pin side seal face 4S and a coupling side seal face 5S are closely stuck together in the desired range when fastening is completed. The occurrence of galling caused by offset contact can be suppressed.

Abstract: PURPOSE:To simplify the circuit constitution by using a phase comparator, an oscillator, a timing adjustment device, and an interrupt controller or the like and matching an operating timing of an interrupt circuit and a transmission timing of an insertion signal with that of a transmission line input signal automonously. CONSTITUTION:An insertion signal IN applied externally is sent to a coupler 14 via an electrooptic converter 34 and a 2nd branching device 35 in matching with a timing of an oscillation output of a VCO 31 by a D-FF 32a. In this case, an interruption controller 33 monitors a branch signal SA and the signal IN and uses an oscillation output of the VCO 31 to generate a control signal S33, which interrupts an interrupt circuit 13 in a timing in matching with a 1st branch output S12-1. Thus, the signal 12-1 at a specific timewise position with respect to a flow of the signal Si through the input transmission line 11 is replaced with the signal IN and it is outputted from an output transmission line 15 via the coupler 14.
