Title: Method for analyzing equivalent in shortage
Inventor: SHIGEMATSU TOSHIO
IPC: G01N23/221
Filed: 1987-09-11
Abstract: PURPOSE:To make it possible to determine an intended element simply, by combining the addition of a radioactive isotope, in which a carrier is absent or the amount of the carrier can be neglected as a principle, and radio activation, which can form the radio isotopes uniformly in a plurality of samples. CONSTITUTION:An objective element to be analyzed in a sample to be analyzed and a standard sample for comparison are labled with two kinds of radio isotopes having the different nuclides of the same element. An insufficient equivalent is separated from the sample to be analyzed and the standard sample for comparison. The radioactivities of the samples, which are separated, are measured. The objective element to be analyzed in the sample to be analyzed is determined based on the measured value. At this time, the addition of the radio isotope, in which a carrier is absent or the amount of the carrier can be neglected in principle, and radio activation, which can form the radio isotopes uniformly in a plurality of the samples, are combined. Thus the objective element can be quantified without necessarily separating the equivalent, when the insufficient equivalent is separated from the sample to be analyzed and the standard sample for comparison.

IPC: G01B11/00
Filed: 1988-09-09
Abstract: PURPOSE:To detect positioning marks at high speed by detecting the position deviation of the first positioning mark which is presently detected based on an image signal, and computing the position of the detecting area of the second positioning mark which is to be detected next time based on said detected data. CONSTITUTION:Positioning marks 2a and 2b incorporate axial line elements indicating directivity. At least the two positioning marks 2a and 2b are arranged on an object to be checked 1 so that the marks are positioned on the extending line of the axial line elements. The position deviation of the first positioning mark 2a which is presently detected based on an image signal is detected.

In this way, the detecting area of the positioning marks after the second positioning mark 2b can be remarkably reduced. The time required for detecting the positioning marks 2a and 2b is shortened. The time required for detecting the accurate position of the object to be checked can be shortened.

Title: Strip line filter
Inventor: ISHIKAWA YOHEI
IPC: H01P1/205
Filed: 1985-10-11
Abstract: PURPOSE:To obtain a small strip line filter high in Q by inductive coupling an active element near the short-circuit end of a lambda/4 strip resonator and operating it by negative resistance in the state of resonance. CONSTITUTION:An end of a lambda/4 strip resonator 18 is connected to a main strip line 14 by a gap capacity formed by a gap 16 and an active element 20 is cou pled near the short-circuit end of the lambda/4 strip resonator 18 by mutual induction by a strip line 22 for phase regulation. The active element 20 operates in the attenuation area, that is, resonance area and shows negative resistance (-r). That is, the active element 20 has ability to supply energy to a resonator 18 in resonance frequency of the lambda/4 strip resonator 18. As energy loss consumed by the lambda/4 strip resonator 18 is canceled by energy supplied by this way, no-load Q(Qo) of the resonator becomes high equivalently.

Abstract: PURPOSE:To improve a spot welding property of a synthetic resin laminate steel plate by a method wherein a layer of synthetic resin mixed with a specified amount of specific metal powder or alloy powder thereof is contact-bonded between a pair of zinc-plated or zinc-alloy-plated steel plates. CONSTITUTION:As to synthetic resin to be used in such a manner that it is held between a pair of plated steel plates, thermosetting resin of thermoplastic resin, epoxy resin or the like denatured by an acid and acid anhydride, or a silane coupling agent or the like can be mentioned, and the thickness thereof is set to be 30 to 100mum in view of a vibration-damping property, a working property, etc. corresponding to the thickness of the steel plates on the opposite outsides. Electroconductive particles to be mixed in a resin layer are of metal powder or alloy powder thereof of which a melting point is 650 deg.C or below, a boiling point 1,600 deg.C or above and Vickers hardness less than 100, and lead, tin, indium, antimony or a uniform substance thereof or the like is used therefor. When the thickness of the resin layer is denoted by (d), it is preferable that the powder of a particle size 0.8 to 2.0 (d) is mixed by 0.2 to 3.0 volume % in relation to the synthetic resin. According to this constitution, a current channel at the time of spot welding can be secured in a stable manner, while the contact area of the steel plates with the metal powder is enlarged, and thus an increase in resistance and heating are prevented.

Title: Wiring board
Inventor: KIKUCHI NORIMI
IPC: B28B11/12
Filed: 1989-09-04
Abstract: PURPOSE:To prevent a 'gas pocket' in a conductive paste which is filled into a through-hole and to improve conductivity of the conductor by forming the through-hole diameter to a size as required at both opening edges on a substrate consisting of a sintered ceramic body and then forming the inner periphery surface into a slanted surface whose diameter become smaller than both opening edges toward the central part. CONSTITUTION:A substrate 1 is mainly produced by laminating and joining thin ceramic sheets and then sintering. A conductive paste 4 is filled into each through-hole 2 which is formed through the substrate 1. The through-hole 2 has a larger diameter D of openings 2a, 2a, a smaller diameter d at the middle part 2b, and has a slanted surface where the diameter of the inner periphery surface becomes smaller from both edge opening 2a, 2a toward the middle part 2b. Therefore, the conductive paste 4 flows and enters easily and smoothly from the opening 2a, 2a of the through-hole 2 toward the middle part 2b and is filled into the inside of the through-hole 2 entirely with no gap. In the wiring board thus constituted, the conductive paste 4 is filled into the through-hole 2 of the substrate 1 with high density, thus producing no 'gas pocket' within the conductive paste 4.

Title: Method and device for bending pipe
Inventor: NAKAMURA TERUSHIGE
IPC: B21D7/025
Filed: 1982-12-28
Abstract: PURPOSE:To improve operability with a simple construction, by exerting a compressive force in the axial direction on a part from the front end to the bending part of a pipe material. CONSTITUTION:A compressive force is exerted on a pipe material 1 in its axial direction from its front end 1' by pulling a wire rod 22 in the direction reverse to the forward one by driving a winding drum 21. Thereafter the pipe 1 is forwarded to the right side by supporting rolls 2, 3 to insert it into a high frequency heating coil 4 thereby the pipe 1 is locally heated. At the same time, a pressing implement 9 is pressed against the front end 1' of the pipe 1 from the upper side to exert a bending moment on the pipe 1. A part heated to a high temperature is bent downward, and a bending part 1'' is pulled to the outside, at the same time, because a compressive force acts on the part 1'' from the front end 1' in the axial direction, but the reduction of wall thickness at the outside bending part 1'' is prevented because the compressive forces in the axial direction compensate each other. The bending is succeedingly performed till the bending part 1'' is bent to about 90 deg..

Abstract: PURPOSE:To prevent a malfunction due to voice, by setting 2-digit personal identification number to a device switching a telephone set and a facsimile equipment, giving a dial, and setting the length of each dial time and the time till the 2nd dial signal. CONSTITUTION:A telephone circuit 4 is connected normally to a telephone set 5 by a contact cml. When a call signal of a facsimile equipment is given to the telephone set 5 and a called party discriminates it as a request of facsimile communication, the same dialing as the preset 2-digit personal identification number is applied. A detection circuit 3 detects a dial signal and gives it to a control circuit 2. The control circuit 2 has the set personal identification number and two timers. When the coincidence is detected from the 1st digit of the identifical number and the length of the timer 1, the 2nd timer is started to decide the 2nd digit of the identification number. When the identification number is coincident, a pseudo signal is sent from the line (a), the facsimile equipment 6 is brought into the automatic incoming state and the contact cml of the relay CML is switched to the position of the facsimile equipment 6. Thus, the malfunction in switching due to voice or holding melody is prevented.
