Title: Electric capacitive roughness gauge
Inventor: MATSUHASHI AKIRA
IPC: G01B7/34
Filed: 1985-04-11
Abstract: PURPOSE:To use an electric capacitive roughness gauge even when maximum height or '+' point mean roughness is employed by finding roughness values of two masters by a probe type roughness gauge and inputting those numerals to a display unit. CONSTITUTION:Two masters which has a proper interval between roughness values are used and roughness values are measured by the probe type roughness gauge; a fine value is denoted as Rm1 and a rough value is denoted as Rm2. Then, the roughness value Rm1 is set in a sum wheel switch 1 and then displayed on the digital display panel 3 while the electrode surface of a roughness detection probe is pressed against the fine roughness master surface. Then, the electrode surface is pressed against the rough master surface to display its roughness on the panel 3 and the Rm2 is displayed while matched with the roughness value of the master by a potentiometer 5. This operation stores R values corresponding to electric capacities Cm1 and Cm2 of the gap due to the roughness of the master in the display unit. Then, when the electrode surfaced is pressed against to a surface to be measured, a numeral which is nearly proportional to the electric capacity of the gap is displayed as the roughness value of a set parameter.

Abstract: PURPOSE:To reduce the useless volume of a combustion chamber to provide high compression ratio by bevelling both sides of a ridge line in the form of a roof on the lower surface of a cylinder head of a V-shaped array four-valve Diesel engine to form the wall surface of both ends spherically. CONSTITUTION:The generation of the lower surface of a cylinder head is achieved by milling cutters 61, 65. When the lower surface of the cylinder head is worked, the rotary axis of the milling cutter 61 is maintained parallel to the axis y while being moved in the direction of the axis x to form a predetermined lower surface of the cylinder head. In this case, the feed-in of the cutter 61 is minimized at the left side edge of the cylinder head, and the cutter 61 is moved right upward to progressively increase the feed-in and then gradually reduce the feed-in from the ridge line y. Similarly, the rotary shaft of the milling cutter 65 is maintained parallel to the axis x, while being moved in the direction of the ridge line y to minimize the feed-in at the feed-in at edges 62a, 62d and make it constant at the central portion. Thus, a bevelled surface 71 provided with an intake valve seat and a bevelled surface 72 provided with an exhaust valve seat are formed in the form of a roof at both sides of the ridge line y.

Abstract: PURPOSE:To improve durability and the linearily of the quantity of fuel injection by circularly chamfering the outer periphery on the coil assembly body side of a movable iron core. CONSTITUTION:The outer periphery on the fixed iron core 12 side of a movable iron core 2, is chamfered in a circular arc shape. When the movable iron core 2 is attracted to the fixed iron core 12 under such a construction, the outer peripheral part (an acute angle part) of the movable iron core 2 is not brought in contact with, but a part of the circular arc surface collides against, the fixed iron core 12. Thereby, the diformation of the movable iron core 2 due to stress concentration and the generation of a scratch on the fixed iron core 2 can be prevented and, since the passage of magnetic flux can be expanded as compared with the case in the conventional techniques, magnetic circuits can be made uniform reducing dispersion in the delay time of valve opening. And, further, the movable iron core nearly makes a line contact, improving the linearily of an injection quantity characteristics due to bounding.
