Title: Electromagnetic ultrasonic flaw detection method and apparatus
Inventor: SUZUKI YOSHIAKI
IPC: G01N29/04
Filed: 1990-09-20
Abstract: PURPOSE:To dispense with an induction coil and to detect even the flaw of a non-magnetic body by allowing a current to flow across two points of a material to be inspected and applying a magnetic field in a direction not parallel to the direction of said current to generate an electromagnetic ultrasonic wave and detecting the reflected ultrasonic wave thereof. CONSTITUTION:All of the conductive contact terminals 11 of a contact terminal group 20 come into contact with the surface of a conductive material 10 to be inspected by the movement of a spring 12. A scanning apparatus successively selects two arbitrary points from all of the terminals 11 and a current J is allowed to flow to the material 10 to be inspected from one terminal. An electromagnetic coil 14 generates a magnetic field H in the material 10 to be inspected by allowing a current to flow. The magnetic flux B obtained this magnetic field H forms a right angle with respect to the current J connecting two points and the electromagnetic ultrasonic wave due to Lorentz force is generated in the direction mutually right-angled to the directions of B and J to propagate. This electromagnetic ultrasonic wave is reflected from a reflecting point to again return to two generated points and voltage is obtained across two points by the action of the magnetic flux B and the force due to the electromagnetic ultrasonic wave to be detected as a current. This current is taken in the scanning apparatus to become a reflection signal.

Title: Infrared emitting spectrophotometric apparatus
Inventor: MASUTANI KOJI
IPC: G01J5/06
Filed: 1987-10-06
Abstract: PURPOSE:To neglect the emission from a background or to deem the same constant during measurement, by shifting the angle formed by a light emitting specimen and an optical axis from a right angle and arranging a trapping black body is opposed relation to the light emitting specimen. CONSTITUTION:A light emitting specimen 1 is arranged so as to be not vertical but slightly inclined with respect to the optical axis connecting a spectrometer 2 and a detector 3 and the object 7 looked by the detector 3 is arranged in opposed relation to the light emitting specimen 1. When the object 7 is set to a low temp. black body, incident light is entirely absorbed by said object 7 and, therefore, the light emitting intensity K' of the object 7 is sufficiently small and emissivity epsilon' can be deemed equal to 1. Therefore, the signal M to be measured of the detector becomes M=KA-KDA (wherein K is the brightness of the light emitting specimen 1, A is an apparatus function and KD is the brightness of the detector 3). From this, a background becomes dependent only on the brightness KD and the function A, and the emission from the background can be deemed constant. Even when the light reflected from the spectroscope 2 in the reflected light from the detector 3 is considered, the emission from the background is deemed constant.

Title: Hot isotropic pressure device
Inventor: AKATSU MAKOTO
IPC: F27B17/00
Filed: 1992-08-28
Abstract: PURPOSE:To obtain a device capable of holding a sealing performance without roughing the sealing surface with a lower part plug of an inner cylinder in a hot isotropic pressurization device. CONSTITUTION:A high pressure resistant cylinder 1 and an upper part opening and a lower part opening of the cylinder 1 are sealed by an upper part plug 2 and a lower part plug 3 with a seal 8, thereby constituting a high pressure chamber 9. A heating device 5 and an adiabatic armor 4 which covers the heating device 5 are installed in this high pressure device 9. The adiabatic armor 4 is placed over the lower part plug 3 in such a fashion that it may move vertically freely while a stopper 4a is installed to the surface of the adiabatic armor 4 and a stopper 1a is installed to the inner surface of the cylinder 1 as well. When taking out a processed material 11 after a high temperature and high temperature processing work, the adiabatic armor 4 falls only by a specified range, but the stopper 4a is engaged with the stopper 1a so that the adiabatic armor 4 is anchored with the cylinder 1, which prevents the adiabatic armor 4 from dropping. This construction makes it possible to take out the processed material 11 and the heating device 5 outside since a sealed area of the cylinder 1 is not affected by the high temperature radiation of the heating device 5 when passing through.

Title: Developing device
Inventor: TAKAHASHI SHUJI
IPC: G03G15/08
Filed: 1985-11-12
Abstract: PURPOSE:To speed up the supply of a developer to a developing sleeve and the interruption thereof by making control in such a manner that a scooping-up roller is rotated in a forward direction to supply the developer to the developing sleeve during development and that the scooping-up roller is rotated backward by >=1 turns in the stage of non-development. CONSTITUTION:The developing sleeve is developed by the other developing device even during the development by a developing device. Said sleeve is rotationally driven in the direction where the developer is conveyed at all times to the developing region even when the development by the developing deice is not executed. On the other hand, the scooping-up roller 2 is kept rotated in the forward direction to transfer the developer to the developing sleeve 1 during the development by the developing device. The scooping-up roller 2 is rotated at least one turn in the backward direction in the stage of non- development. Since the developer attracted to and conveyed by the roller 2 is returned to a developer reservoir, the conveyance of the developer to the developing region is immediately stopped even if the developing sleeve 1 rotates forward. The quick and sure ear cutting is thus executed.

Abstract: PROBLEM TO BE SOLVED: To facilitate assembling work by arranging an elastic material on a central shaft secured with a magnetic circuit and a damper thereby ensuring machining accuracy of the elastic material and suppressing deformation at the time of assembling. SOLUTION: A magnetic circuit is formed by clamping a permanent magnet disc 2 between a yoke 1 and a plate 3.
