Title: Conjugated roll for rolling
Inventor: OSHIMA MASAHIKO
IPC: C21D9/38
Filed: 1989-05-08
Abstract: PURPOSE:To produce the continuously build-up cast roll having a shaft material which is high in strength, less in residual stress and has high reliability by using a steel product contg. Ni for the shaft material and lowering the initiation temp. of the transformation expansion in the shaft material arising at the time of cooling in a quenching treatment. CONSTITUTION:The shaft material of the conjugated roll for rolling is made of a cast steel or forged steel contg., by weight, 0.3 to 1.0% C and <=3% Ni. The roll is subjected to quenching at a rate of 0.3 to 7 hours half-cooling time from 900 to 1200 deg.C after roll casting, by which the initiation temp. of the transformation expansion arising in the shaft material is lowered down to <=700 deg.C. The shaft material of the roll is, therefore, enhanced in the strength and lessened in the residual stress in the axial direction, by which the roll having the high reliability to a large bending stress is obtd.

Abstract: PURPOSE: To measure the wearing characteristic of a thin film material and, at the same time, to digitize the wearing state of a sample in real time during tests by comparing the initial picture of the rear surface of the sample with sampled picture signals and finding the separation rate of the sample from the data. CONSTITUTION: A sample S constituted by forming a thin film on a substrate is linearly moved by means of a sliding device (c) while its surface is pressed with the indenter (a) of a loading device (b). Before starting tests, an image pickup means (d) picks up the image of the rear surface of the sample S by dividing the picture into a plurality of picture elements and a picture storing section (e) stores the initial picture. When the tests are started, a sampling section (f) fetches picture signals from the means (d) in prescribed periods and a discriminating section (g) discriminates the positions of the picture elements which largely change than a reference value does by comparing the picture signals fetched from the means (d) with the stored (e) initial picture.  A position storing section (h) stores the discriminated positions of the picture elements and an arithmetic section (i) finds the rate of separation by using the discriminated results of the section (g) and positional data stored in the section (h) whenever picture signals are sampled.

Title: Production of rough shape steel ingot for h-shaped steel
Inventor: MATOBA HIROYUKI
IPC: B21B1/08
Filed: 1989-05-09
Abstract: PURPOSE:To improve the shape of the web part in the non-stationary shape of the top and bottom of a material by forming recesses in the part of the stock corresponding to the web part of a rough shape cast ingot in the initial stage of a rough shape rolling, and then subjecting the stock to the rough shape rolling and shaping. CONSTITUTION:A large thickness reduction is necessary for forming the part of a beam blank corresponding to the web part in the case of obtaining the beam blank from the stock having a flat section. The recesses 11 are formed in the part of the stock 1 corresponding to the web part 21 of the rough shape steel 21 in the initial stage of the rough shape rolling in the method for producing the rough shape steel ingot 2 for an H-shaped steel from the stock 1 of the ingot having the flat section. The elongation at the time of the rolling is suppressed in this way and the thickness decrease in the part corresponding to the web is dealt with by the expansion of the stock width on the increase of the volume in the flange part. The stock is thereafter subjected to the ordinary rough shape rolling and shape rolling, by which the shape of the web in the non-stationary shape parts at the top and bottom of the material is improved and the rolling yield is greatly improved.

Title: Fuel injection device
Inventor: KANOU KOUJI
IPC: F02M69/48
Filed: 1982-07-02
Abstract: PURPOSE:To prevent the fly-up phenomenon of the injected fuel and improve the atomizing property as well as the responding property of the device by a method wherein the sectional area of the path of a venturi part, into which a fuel injection valve is inserted, is made larger than the same of the periphery of a throttle valve under fully opened condition thereof simultaneously with the opening of the outlet port of a bypass air path. CONSTITUTION:A part of suction air passes through the bypass air path 10 and is entered into the venturi part through outlet ports 8. Fuel, supplied from the fuel injection valve 9, is atomized and mixed with the suction air simultaneously when it is injected into the stream of the suction air, then, is sucked into the engine after passing around the throttle valve 5. When the engine is brought into a high-load operating condition and the throttle valve 5 is set at the fully- opened condition as shown by a broken line, a vacuum at the downstream of the throttle valve 5 becomes higher than the same generated in the venturi and the atoms of the fuel, injected from the injection valve 9, passes around the throttle valve 5 regularly without being flown up, thereby improving the atomization as well as the promotion of the supply of the fuel.
