Abstract: PROBLEM TO BE SOLVED: To obtain ceramics having low friction and high strength by forming stable pores having oil adsorptivity in a surface layer which becomes a sliding face by oxidation treatment and heat treatment. SOLUTION: A surface layer A comprises a grain aggregate, which is continuous from the surface toward the interior, and has higher hardness than the interior. Pores 10 which extend in a direction perpendicular to a sliding face 6 are dispersed in the surface layer A and a coating 10a of an iron compound is formed on the insides of the pores 10. The grains of the aggregate forming the surface layer A are silicon nitride grains and the sliding face 6 partially has silicon carbide grains. The pores 10 are impregnated with lubricating oil or grease.

Title: Grinding machine
Inventor: FUKUMASA AKITO
IPC: B24B17/10
Filed: 1986-02-19
Abstract: PURPOSE:To aim at improvement in operation controllability as well as to a wheel spindle stock from being overrun, by selecting a traverse direction of the wheel spindle stock manually by switch motion during traverse operation of the wheel spindle stock by a numerical control system. CONSTITUTION:At automatic traverse grinding by means of numerical control, a wheel spindle stock 3 reciprocates several times at the set speed in a traverse direction between traverse target positions Z1 and Z2 at both forward and backward sides as its grinding wheel 1 is doing infeed to an inner surface of a workpiece W by an infeed device 4, thus the automatic traverse grinding takes place. At this time, when a machining compensation is required for the workpiece W, each time the grinding wheel 1 situated in one side of both ends of the compensation required range a machining compensation switch is pushed by an operator. With this constitution, the traverse direction is selected to the opposite direction at both ends of the compensation required range of the workpiece, so that this compensation required part alone is ground. On top of that, owing to continuation of the automatic traverse grinding, the wheel spindle stock is reversed in the travel direction at the traverse target position without fail.

Abstract: PURPOSE:To enable to completely use nearly the total quantity of hot water in a hot water storage tank without lowering its temperature yet by checking the water supply when a system for supplying hot water by lots is selected by a constitution wherein the selection between the system for supplying hot water by overflowing and the system for supplying hot water by lots can be possible by changing-over a three- way solenoid valve. CONSTITUTION:A hot water supply pipe 8 for overflowing supply is connected at a position lower than an upper limit hot water level H determined by an upper limit level switch 5 and at the same time a hot water supply pipe 10 for lot supply is connected at a position lower than an lower limit cold water level L determined by a lower limit level switch 6 in a hot water storage tank 2. The other ends of the hot water supply pipes 8 and 10 are connected to the inflowing ports of a solenoid controlled three-way directional control valve 11, the discharge port of which is connected to a hot water supply pipe line C. When a system for supplying hot water by overflowing is selected by the solenoid controlled three-way directional valve 11, a control device 3 sends a ''open'' signal to a solenoid controlled feed water valve 4. On the hand, when a system for supplying hot water by lots is selected, the control device 3 keeps on sending a ''close'' signal to the valve 4 in order to act for stopping water supply.

Title: Painting method
Inventor: OKUDA ITSUPEI
IPC: B05D3/00
Filed: 1980-03-19
Abstract: PURPOSE: To prevent occurrences of swellings, pin-holes, craters, etc., on the painted surface, by placing the painted surface on which a paint has been applied in an atmosphere higher than the atmospheric pressure by a prescribed value and hardening the paint.  
     CONSTITUTION: While paint film 11 applied on the surface of article to be painted 10 maintains its fluidity and restorating property, article to be painted 10 is placed on table 3 by opening door 2. Then door 2 is closed and a compressed air is supplied by opening valves 6 and 7. In this case, the air is discharged through valve 7, but the inside of container 1 can be maintained at a required pressure by adjusting valve 9. When paint film 11 is hardened to a prescribed degree and it cannot be restored, article to be painted 10 is taken out from container 1 and the work is completed. In this case, since the inside of container 1 is maintained at a pressure higher than the atmospheric pressure, air or vapor contained between the surface of articles to be painted 10 and paint film 11 will not be expanded even when the temperature is raised and no swelling. etc., will be produced. Thus a smoothly finished painted surface is obtained.
