Title: Sealring in floating seal
Inventor: YOKOSHIMA NAOHIKO
IPC: B05B7/22
Filed: 1982-11-24
Abstract: PURPOSE:To provide durability of a floating seal for a travelling section of construction equipment by allowing the thickness of high hardness coating on the inner peripheral tapered surface to form the whole desired engaging surface of high hardness material. CONSTITUTION:A seal ring 1 comprises flat surfaces 3 provided in the outer peripheral side of opposed inside surface with recesses, and tapered surfaces 5 at the inner peripheral side, and a portion of the flat surfaces 3 provides seal portions bearing against each other. This tapered surface 5 is formed with WC system high hardness coating 40' by plasma metal spray so that the thickness S of the coating 40' permits a desired seal portion t to be formed of high hardness material. This thickness s is obtained from an angle alpha of the tapered surface 5 according to the formula S=tXsin alpha. For example in the normal 100 phi seal ring, since the engaging surface t is 1-2mm. and taper angle is 1-2 deg., the thickness of high hardness coating is 0.09mm.. Thus, the sealing ring with excellent durability can be produced simply and economically.

Title: Electronic camera for still picture
Inventor: HORIO MOTOHIKO
IPC: H04N5/238
Filed: 1986-09-02
Abstract: PURPOSE:To enable instantaneous diaphragming in a still mode and the smooth following the change in light of an object in the movie mode by driving a diaphragm mechanism with a stepping motor. CONSTITUTION:If a release button(switch) 74 is depressed during the image pickup in the still mode, an arithmetic/exposure control circuit 2 calculates a suitable shutter speed and diaphragm value, and transmits a pulse to a stepping motor drive circuit to let a diaphragm 12 close to the calculated value. A release signal is ignored during the movie mode photographing, and photometry is started. The stepping motor is driven based on the result of the photometry, Since the controlling of photometry and diaphragm value is executed with the diaphragm narrowed yet, the stepping motor only needs to compensate for the variation in the brightness, therefore, in comparison with the still mode, the amount of action of the diaphragm comes smaller.
