Title: Medium carbon alloy steel for surface hardening and heat treatment
Inventor: NAKAMURA KOUJI
IPC: C22C38/44
Filed: 1981-10-01
Abstract: PURPOSE:To provide the titled alloy steel having a restricted composition consisting of C, Si, Mn, Ni, Cr, Mo and Fe and capable of forming a structure with superior properties by carbonitriding and austempering. CONSTITUTION:The titled alloy steel consists of 0.45-0.60% C, <=0.50% Si, 0.40-1.30% Mn, <=4.00% Ni, 0.35-0.55% Cr, <=0.70% Mo and the balance Fe with impurities. The steel is carbonitrided for a short time to add carbon and nitrogen to the surface layer, and it is austempered by quenching in a hot bath at about 230-300 deg.C for a time enough to finish the lower bainite transformation of the base part and not enough to start the lower bainite transformation of the surface layer. Air cooling or water cooling is then carried out. By the cooling the surface layer causes martensite transformation to give high surface hardness and surface residual compressive stress, and a lower bainite structure with >=about 600 Hv hardness is formed in the base part.

Title: Cylinder for two-cycle engine
Inventor: KINOUCHI SOSUKE
IPC: F02F1/00
Filed: 1985-07-12
Abstract: PURPOSE:To provide a cylinder of high roundness, by providing honing surface pressure adjustment recesses in the inside surface of the cylinder so that the recesses are located on the productions of both the ends of a rib which divides ports which are opened and closed by a piston. CONSTITUTION:Shallow recesses 16, 17 are provided in the inside surface 2 of a cylinder by casting so that the recesses are located on the productions of the upper and lower ends of a rib 7 which divides two exhaust ports 3 from each other. When the inside surface 2 of the cylinder is finished with a hone 18, the hone does not come into contact with the inside surface 2 in the recesses 16, 17 but comes into contact therewith at the rib 7 etc. Since the pushing load acting to the rear of the hone 18 is constant, the pressure on the surface 7a of the rib 7 does not becomes lower than that on the surface of the other portion of the cylinder. For that reason, the finishing with the hone 18 is performed so that the surface 7a of the rib 7 does not project from the surface of the other portion of the cylinder. As a result, manual finishing work is not required after the hone finishing, and seizure is prevented.

Title: Traverse device
Inventor: SUGIOKA TAKAMI
IPC: B65H54/28
Filed: 1985-07-13
Abstract: PURPOSE:To improve durability of a slider considerably in a thread winding machine by making the center of gravity of a traverse slider to be located at a guide rail section and bringing a rail-guided part into contact with a shock receiving member. CONSTITUTION:A cam 3 rotatably installed in a case 6 is driven by a motor. A cam follower 1e of a slider 1 equipped with a yarn guide 2 is engaged with a spiral, endless groove 3a so that the slider 1 guided with guide surfaces 4a and 5a of respective guide rails 4 and 5 moves to the left. Upon reaching the turning point, the slider 1 reverses counterclockwise and the sliding surface strikes against a side wall 3b formed at the traverse turning point of the cam 3 and the shock is absorbed. Here, since the center of gravity G is located at the location guided by the guide rails 4 and 5, the slider 1 can be made to be of small size and light weight. Further, since shearing force and the like due to the shock receiving member 3b is absorbed, durability of the slider can be improved.

Abstract: PURPOSE:To prevent the abnormal consumption of arc electrode in a sheet material- bonded part by bonding a sheet material consisting of hard high alloy powder and resin binder to the sliding part of a camshaft and performing remelting hardening from a sheet material-unbonded part by means of electric discharge arc while turning the camshaft. CONSTITUTION:A high alloy powder is melted by means of a high energy arc, such as TIG arc, on the sliding part in a cam surface 1 of a camshaft W for automobile engine, and a hard surface having superior wear resistance is formed by means of melting together with the alloy powder due to remelting in the cam surface. At this time, a part 1a in which a sheet material 2 consisting of high alloy powder and resin binder is bonded to the cam 1 surface and an unbonded part 1b are formed on the surface of the cam 1. An arc 4 is easily produced first in the sheet-unbonded part 1b by means of a TIG arc torch 3, and then, a spacing L2 between an electrode 3a at the end of the torch 3 and the sheet material 2 is increased in the sheet-bonded part 1a while turning the cam 1, by which the consumption and erosion of the electrode 3a at the end of the torch 3 owing to the allow material powder can be prevented. A remelted alloy layer having high hardness and excellent in wear resistance can be formed easily and stably on the sheet material-bonded part 1a.

Filed: 1993-06-25
Abstract: PURPOSE:To improve adjustment precision by extracting respective channel outputs from an image pickup means comparing the extracted data, operating a DC voltage level adjustment quantity and a gain adjustment quantity, and automatically adjusting a DC voltage level and a gain. CONSTITUTION:A CPU 10 reads an offset error and a gain error out of an EEPROM 14 and sends them out to a D/A unit 11.

A CCD 1 picks up a subject image, accumulates electric charges corresponding to the luminance, pixel by pixel, and outputs the accumulated pixel information in synchronism with the clock from a CCD driving circuit 2. The outputted information is outputted to the circuits 4a-4c through noise reduction and sample and hold circuits 3a-3c and the reference DC voltages levels of the respective channels are adjusted and equalized. Further, the gains of amplifying circuits 5a-5c are adjusted so that the signal amplitudes of the respective channels become equal. Consequently, the adjustment precision is improved and the adjustment is automated.
