Title: Method for deciding corrosion resistance of zirconium-based alloy
Inventor: YASUDA TAKAYOSHI
IPC: G01N17/00
Filed: 1988-09-09
Abstract: PURPOSE:To enable easy decision, on the outside of a furnace, as to whether the corrosion resistance in the furnace is superior or inferior by making prescribed corrosion test of the case in which test pieces are previously irradiated with gamma rays and the case in which the test pieces are not irradiated with the gamma rays and making decision by comparison of the change rates of the weights before and after the tests. CONSTITUTION:The pickling samples of an X material and Y material are first subjected to the corrosion test (a) for 70 hours under irradiation of 2.1X10<15>eV/cm<3>/h gamma rays and the corrosion test (b) for 70 hours under non-irradiation at, for example, 300 deg.C, 10.5MPa, and 40ppm dissolved oxygen concn. These test pieces are then tested in high-temp. steam for 24 hours at, for example, 510 deg.C and 10.5MPa on the outside of the furnace and the increases of the weight of the test pieces after the tests (a) and (b) are measured. The measurement results of the non-irradiated X material 11, the irradiated X material 12, the non-irradiated Y material 13, and the irradiated Y material 14 are as shown in the figure. Namely, the X material having the excellent corrosion resistance in the furnace has the small influence of the irradiation of the gamma rays in the test. On the other hand, the influence of the irradiation of the gamma rays is significant and the weight thereof increases extremely large in the case of Y material. Whether the corrosion resistance is superior or inferior is thus decided easily in a short period of time on the outside of the furnace.

Title: Method for cutting semi-plastic lightweight foamed concrete
Inventor: OZAKI KENJI
IPC: B26D1/547
Filed: 1987-09-10
Abstract: PURPOSE:To make the cut-off surface smooth and prevent striped pattern from developing by a method wherein at least three wires, front and rear of which pass the same portion, are disposed in tension in such a manner that any two wires lying before and behind each other are set on a cutting frame so as not to be parallel to each other and at the same time the diameter of the wire, which comes into contact with concrete infront, is set to be not smaller than that of the wire, which comes into contact with concrete arrear. CONSTITUTION:A cutting frame 2 runs in the direction indicated with the arrow A relative to a semi-plastic body 1. The foremost wire 3a in the running direction is vertical, the second wire 3b is out of upright and the third wire 3c is disposed in tension so as to be not parallel to the wire 3b. The cutting frame 2 is rocked vertically as indicated with the arrow B by means of a driving device. The diameter of the wire, which comes into contact with concrete infront, is set to be not smaller than that of the wire, which comes into contact with concrete arrear. When said diameters of wires are different from each other, the preferable difference between the diameters of the wires adjoining to each other is 0.5mm or less. Though nearly vertical streaking pattern is developed by the wire 3a, which firstly comes into contact with semi-plastic lightweight foamed concrete, since said wire instantaneously stops twice per stroke, said pattern is rubbed off by two or more wires, which come into contact with concrete behind, resulting in realizing a surfacce, which is nearly smooth in appearence.

Title: Instrument for measuring quantity of abrasion
Inventor: TERAJIMA YUKIO
IPC: G01B7/00
Filed: 1985-10-09
Abstract: PURPOSE:To enable the quantity of abrasion to be automatically and accurately measured by providing a plurality of conductors for forming electric paths such that part of the electric paths gradually leaves from a sliding surface and detecting the disconnection of the electric paths formed by the conductors. CONSTITUTION:When the sliding surface of a substrate 1 is displaced in a direction shown by an arrow due to abrasion and a short-circuiting conductor 3 is scraped off from its end, first the conduction between the first conductor 21 and the short-circuiting conductor 3 is disconnected. Then, a signal is fed from a signal processing circuit 8 to a display 9 and the quantity of abrasion corresponding to the nonconductive state of the first conductor 21 is digitally displayed. Thereafter, the same display corresponding to the abrasion is sequentially conducted. Therefore, by burying the substrate 1 in the sliding portion of, for example, the cylinder liner of an internal-combustion engine or attaching the substrate 1 to the side of the cylinder liner in advance, the quantity of the abrasion is automatically detected and displayed by the nonconductive state of the conductors 21, 22,...2n as the abrasion proceeds, for example, every 0.1mm.

Title: Elastic crawler
Inventor: SAKAI KENICHI
IPC: B62D55/253
Filed: 1988-09-07
Abstract: PURPOSE:To make centering functioned between both of two parties when each engaging bar of a driving wheel is engaged with each tilted surface, and thereby eliminate a particular run-out prevention member by tilting the engaging section of a projection in such a way that the projection at the center section side in the lateral direction of an endless belt is narrow in width, but is wider toward the outer side of it. CONSTITUTION:An elastic crawler 2 which is wound over a driving wheel 1 provided with numbers of engaging bars 4 in the circumferential direction around a disc section 3, is equipped integrally with an endless belt 5 made of an elastic member such as rubber and the like, numbers of grounding lags 6 formed on the outer circumference of the belt at equal intervals, and with numbers of driving projections 7 which are formed in the inner surface of the endless belt 5 acting concurrently as a run-out prevention member. Each projection 7 arranges engaging sections 8 at the both sides of it in the rotating direction. In this case, each projec tion 7 is formed in such a way that the width B1 is narrow at its center section of the endless belt 5 in the lateral direction, but its width B2 is maximum at the outer side in the lateral direction. This constitution thereby forms the base section 9 of the projection 7 into a V-shape in such a way that the angle of alpha is formed from the outside of the endless belt 5 toward the center section wherein the engaging sections 8 at both of the sides are formed into tilted surfaces accodingly.

Title: Method for controlling deburring robot
Inventor: KAWASHIMA NORIHIKO
IPC: B24B49/16
Filed: 1991-09-05
Abstract: PURPOSE:To shorten the grinding time, and improve the reliability of the work by changing the grinder feeding speed on the basis of a change of the grinder current, and giving a compliance to the grinder feeding direction in response to a grinder current value. CONSTITUTION:A compliance coordinate converting unit 3 converts a track command position to a value of a rectangular coordinate system having one axis in the tack spectrum direction. A joint coordinate converting unit 4 converts the command position of a grinding point of a grinder to a joint coordinate. When the grinder collides with an excessive burr, a speed reduction command unit 6 outputs the speed reduction command to a track interpolating unit 1, and a compliance gain computing unit 7 outputs a gain. As a result, a gain (K)not equal to 0, and a coordinate value in the feeding direction is added to the feeding direction inversely to return the command position. With this inverse operation of compliance, lock of a grinder is prevented without passing-over of the command position.

Filed: 1986-09-24
Abstract: PURPOSE:To shorten a turn-off time by providing a drain electrode to a drain region for connection to both one conductivity type base layer and a reverse conductivity type drain layer on the surface. CONSTITUTION:A drain electrode 3 is connected to both a P<+> type drain layer 7 and an N<+>-type buffer layer 11 to form an anode short-circuit structure on an element surface so that electron are removed without intermediary of the layer 7 in the drain region.
