IPC: F01L1/24
Filed: 1982-06-04
Abstract: PURPOSE:To prevent an irregular wear etc. caused by an irregular contact of a cam by a method wherein an adjuster is constructed such that it is provided with a column member having a substantial vertical axis in respect to a plane in which a rocker arm can be oscillated and supporting the rocker arm in such a way as it may be oscillated. CONSTITUTION:When an engine is started to operate, a cam shaft 13 is cooperatively rotated, a rocker arm 21 is oscillated in its oscillating plane including its longitudinal center axis (x) and having the desired angle alpha in respect to an axis (y) of a column member 26 around a fulcrum point of the column member 26 in the adjuster 22 tdhrough a cam 14 to cause a valve 15 to be reciprocated. At this time, since the rocker arm 21 is supported by the column member 26 inserted into the fitting groove 21c, it can prevent the rocker arm 21 from falling around the center axis (x) even if the same is fallen toward the rocker arm 21 and a momentum is applied thereto. Therefore, it is possible to prevent an irregular contact between the cam 14 and the follower 21a and their irregular wear during a high speed operation of the engine.

Title: Digital image decoding device/method and supply medium thereof
Inventor: ONO TAKESHI
IPC: H04N19/177
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To improve the use efficiency of a reference picture data storage part band width by storing image data in a range which has the possibility to be referred to at the moving compensation prediction, apart from reference picture data. SOLUTION: The front and back reference images of image data equivalent to 144 lines from the head of the reference image are transferred to a moving compensation buffer memory 16 from a frame memory 2 by a line unit while data on corresponding to a hundred and forty four line amount from the final line of the front picture and succeeding lines are decoded. A moving compensation prediction part 47 reads the required image data from the memory 16 by a macro block unit, based on a moving vector and operates the moving compensation prediction value of each macro block. Since the memory 16 is formed in same IC 1 as the moving compensation prediction part 17, data can be transferred at sufficient speed even in the macro block.  Since data is transferred from the frame memory 2 to the memory 16 in the line unit, high speed transfer such as burst transfer becomes possible and the band width use efficiency of the frame memory 2 can be improved much more than the transfer of the macro block unit.

Title: Bar material joining method
Inventor: KASHIMOTO FUMIO
IPC: H05B6/10
Filed: 1993-03-30
Abstract: PURPOSE:To stably maintain the proper final upset quantity and to improve the joining quality by adding the specified initial pressure to the joining surfaces to perform heating and specifying the pressurizing force during heating. CONSTITUTION:When bar materials to be joined are abutted on each other with insert material held between the joining surfaces, and heated and held above the melting point of the insert material to perform diffusion joining, the initial pressure of 300-500kgf/cm<2> is added to the joining surfaces of the bar materials to perform heating. The pressurization of 150-380kgf/cm<2> is started after 10-60 seconds since the measured temperature of the abutted part attains the holding temperature above the melting point of the insert material. The pressurization is stopped at a point of time when the upset quantity attains 15-20% of a nominal outside diameter of the bar materials. Consequently, upset by pressurization and residual pressure after pressurization is stabilized and the upset quantity as a target can be maintained stably. In addition, coil damage due to excessive swelling of a joined part is prevented.
