Filed: 1989-12-26
Abstract: PURPOSE:To improve the processing efficiency by reading out the output signal of a switch selected by a switch selecting means responding to an address signal sent out successively from the direction being different from the selected direction and detecting the presence of a key operation. CONSTITUTION:A switch selecting means 3 for selecting a switch of one direction of a row direction and a column direction of a switch group 2 by an address signal AB is provided.

Title: Highly durable magnesia-carbonaceous refractory
Inventor: MATSUI TAIJIRO
IPC: C04B35/043
Filed: 1993-12-28
Abstract: PURPOSE:To eliminate problems of disintegration of a grain boundary and outflow due to impurities deposited in the crystal grain boundary in an electrofused magnesia clinker used as an aggregate raw material for conventional magnesia-graphitic refractory and improve the corrosion resistance and durability. CONSTITUTION:This highly durable magnesia-carbonaceous refractory is obtained by blending a magnesia clinker aggregate with a graphitic material and a binder. In the refractory, the magnesia clinker aggregate is prepared by electrofusing seawater magnesia having >=99.9% purity, providing an electrofused magnesia clinker composed of a single crystal having >=1000mum grain size, blending the resultant clinker in a polycrystalline magnesia clinker, pulverizing and controlling the size of the resultant magnesia clinker blend and using the magnesia clinker having the grain size controlled within the range of 0.074-3mm. Impurities are not deposited in the grain boundary and converted into a solid solution in the magnesia to promote the coarse-grain crystallization. Thereby, a single crystal having >=1000mum grain size is obtained and used as a constituent aggregate for a magnesia-graphitic refractory. As a result, an influence of permeation of a slag into the grain boundary in refining can be reduced to prevent the disintegration by thermal shock.

Abstract: PURPOSE: To reduce the load needed for tilting a lock portion downward and Wallow the lock portion tilted downward to easily return upward by connecting the lock portion to a receptacle housing by means of a hinge portion having a thinner wall than a hinge connection. CONSTITUTION: As a receptacle housing 5 is inserted into a header housing 105, a lock portion 1 is tilted downward in such a manner that it is pressed by the retaining wall 5A of the housing 105. The other side piece 8 of the lock portion 1 abuts to the abutting part 10B of a spring 10, and the lock portion 1 depresses the spring portion 10. As the housing 5 is inserted, the lock portion 1 depresses the spring portion 10 about the fulcrum 10P of the spring portion 10. As the housing 5 is inserted under this state, the pin 106 of the housing 105 is inserted to a connecting position above the spring portion 10. Once the main body portion 1E of the lock portion 1 has passed beyond the wall 5A, the lock portion 1 is returned to an upper lock position and locked.  Thereby the contact surface 10a of the contact portion 10A of the spring portion 10 makes contact with the contact surface 106a of the pin 106, connecting a terminal 6 with the pin 106.

IPC: B41M5/52
Filed: 1989-12-27
Abstract: PURPOSE:To improve the surface smoothness of image receiving paper, to enhance ink transfer properties and to form a highly detailed recording image having high resolving power by adding calcium carbonate to the ink receiving layer on a paper base material as a pigment component in a form of calcite type globular secondary aggregates. CONSTITUTION:In thermal transfer recording image receiving paper using heat-meltable ink, the ink receiving layer on a paper base material contains calcium carbonate as a pigment component in a form of calcite type globular secondary aggregates. By incorporating calcium carbonate in a form of calcite type globular secondary aggregates, the fixing properties of the transferred ink is enhanced and the forming degree of the protruding parts on the surface of the image receiving paper accompanied by the reception of the ink is suppressed to prevent missing and cutout. The content of calcium carbonate in a form of calcite type globular secondary aggregates is set 40 - 100% by wt. of the pigment component contained in the receiving layer. When the content of calcium carbonate is less than 40wt.%, the oil absorbability of the ink receiving layer is not sufficiently improved and the excellent fixing properties of the ink are not obtained.

Title: Material testing machine
Inventor: KAMEGAWA MASAYUKI
IPC: G01N3/06
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To attain bath a wide measuring range and a high resolution by using a strain gauge type elongation measuring device when the elongation of a test piece is within the elastic range, and a video type when it is out of the elastic area. SOLUTION: The tensile quantity of a test piece TP is increased by a prescribed quantity to apply a tensile load, and the tensile load and elongation are measured while repeating this. Two extensometers are selectively used in the measurement of elongation to mutually compensate the respective disadvantages and effectively utilize the advantages. Namely, when the measuring range is not wide, but high measurement precision and high resolution are required in the elongation within the elastic range of a test material, the measurement is performed by use of a strain gauge type extensometer 2, and a video type extensometer 1 is used in the measurement requiring no high measurement precision but considering a large elongation or breakage exceeding the elastic range.  According to this, a wide measuring range and a high measurement precision (resolution) is compatible in one material testing machine.
