Title: Ceramic excellent in sliding characteristic and its production
Inventor: INOUE SHIGEO
IPC: C04B41/91
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To improve the sliding characteristics of the surface structure of a ceramic by forming long-periodic unevennesses so as to retain a lubricating oil and short-periodically reducing the surface roughness. SOLUTION: This ceramic has a surface structure thereof in which long- periodic unevenesses so as to hold a lubrication oil are formed on the surface and the surface roughness is short-periodically small. Si3 N4 , SiC, Al2 O3 or ZrO2 or a composite ceramic prepared by dispersing other ceramics in the ceramic as a substrate, e.g. an Al2 O3 /ZrO2 -based, an A2 O3 /TiC-based or an Al2 O3 /SiC whisker/ZrO2 -based ceramic is used as the ceramic. The surface roughness of the long-periodic surface part is 0.1-1.0μm and the average roughness indicating the roughness of the short-periodic surface part is 0.01-0.1μm. Furthermore, the average roughness for 10 points of the roughness in the short-periodic surface part is 0.2-0.6μm and the maximum roughness is 0.3-1.5μm.  The surface structure can be changed with the surface roughness of a grindstone in a barrel grinding method used herein. For example, a coarse grindstone having about No. 400 grain size is initially used and then a grindstone composed of abrasive grains is then used. A grindstone composed of fine grains is finally used.

Title: Electroless plating method for metal on inside surface of pipe
Inventor: KOZONOE ATSUSHI
IPC: C23C18/31
Filed: 1981-12-11
Abstract: PURPOSE:To compensate the fluctuations in the temp. of a plating soln. in the stage of measuring the metal plating thickness in a pipe during plating by an eddy current flaw detecting method by using a dummy pipe which is not plated even when the plating soln. is run therein as a pipe for a standard coil. CONSTITUTION:In the case of coating copper on the inside surface of a zircaloy pipe which is a cooted pipe for nuclear fuel two pieces of said pipes are prepared. The one is used as a pipe 1 to be plated which is adsorbed thereon with metallic Pd as a catalyst and the other is used as a dummy pipe 2 which is coated and cured with epoxy resin plating resist to prevent depostion of metal and sticking of metallic powder. Thereafter, coil holding bodies 4 which are fixed with a measuring coil 5 and a standard coil 6 are mounted to the pipes 1, 2 respectively. The impedances of both coils are balanced and the plating soln. is circulated approximately at the same flwo rate in the pipes 1, 2. The unbalanced voltage of a bridge which increases with an increase in the thickness of the plating layer of the pipe 1 operates a liquid temp. control system 12 and is fed to a monitor 17 for plating thickness as well. When the prescribed thickness is attained, the circulation of the plating soln. is stopped by a control system 13 for motor.

Title: Valve driving method and valve drive gear in internal-combustion engine
Inventor: HIRANO MASAAKI
IPC: F01L9/20
Filed: 1981-12-10
Abstract: PURPOSE:To make it possible to control timing of a valve in response to the driving condition by electromagnetically driving the valve. CONSTITUTION:When power is conducted to a first coil 14 and to a second coil 16, the same polar magnetic field is produced on a bearing 17 which is the first polar strip and a second polar strip 15. By repulsion of the both, a valve 13 comes down overpowering resilience of a spring 18, and an air inlet port 12 is opened. When current rate to be supplied to the first coil 14 and to the second coil 16 is reduced, the valve 13 is risen and the air inlet port 12 is closed because of resilience of the spring 18. Thus, opening and closing cycle and lift of the valve can be controlled in response to driving condition of the engine.

Title: Structure of connections of manhole wall block
Inventor: HASHIMOTO TAKEO
IPC: E02D29/12
Filed: 1981-12-11
Abstract: PURPOSE:To raise the water tightness and durability of joints of manhole wall blocks by a method in which elastic and water-proof band materials are connected with cement mortar on its both sides between each of a lower body, wall, and at central parts of the joints of the wall blocks. CONSTITUTION:The spaces between each of the lower part 1 of concrete, the joint surface 3 of manhole wall block 2A, and wall blocks 2A and 2B are filled with elastic and water-proof band material 5B such as synthetic rubber, while cement mortar pieces 6 sandwich said material 5B inbetween. By this structure, water tightness is ensured between the lower part 1 of placed concrete and the wall block 2A and also between the wall clocks 2A and 2B due to the band material 5B having an elastic deformity. Thus, the water shielding effect of the joints can be raised and maintained even when the manhole structure is moved by earthquake and ground subsidence.

IPC: F16C33/10
Filed: 1992-07-06
Abstract: PURPOSE:To provide a journal bearing difficult to generate centrifugal whirling and self-excited vibration of a rotary shaft even in the case of rotation at a high speed by forming an axial direction width of a bearing surface in such a manner as to be gradually reduced from approximately the center in the circumferential direction of the bearing surface toward upstream of rotation of the rotary shaft. CONSTITUTION:In a journal bearing, a bearing surface 4 is cut on both sides in the axial direction of a dam 8 on both sides in the axial direction of oil grooves 2, thus obtaining face recessed parts 71. The recessed part 71 is formed into a partial trapezoidal shape which is formed approximately in the same line of the oil groove 2 in the axial direction upstream in the rotating direction of a rotary shaft 9 while it is formed in such a manner as to be inclined downward of both ends from the center in the axial direction downstream in the rotating direction of the rotary shaft 9. Consequently, an area upstream of the bearing surface is reduced and lateral force is reduced in the load direction of lubricating oil with respect to the rotary shaft 9 so that centrifugal whirling and self-excited vibration of the rotary shaft 9 is difficult to be generated.
