Title: Photometric device of camera
Inventor: HIRAI ISAMU
IPC: G03B17/28
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To obtain a photometric device of camera realized by an optical means whose constitution is simple and whose operation is easy by changing the photometric sensitivity distribution on the light receiving surface of a light receiving sensor interlocked with the switching of a photographic format. SOLUTION: A photographic format switching mechanism 14 is provided with light shielding plates 16 and 17 and a light shielding plate driving laver 18. When the lever 18 is turned, the plate 16 is moved in the leftward direction and also moved in the downward direction. On the other hand, the plate 17 is moved in the rightward direction and also moved in the upward direction. As a result, an exposure window 13 becomes a panoramic picture plane having shape whose distance in an up-and-down direction is narrowed, whereby the photographic format is switched to the panoramic picture plane. Interlocked with this switching, three kinds of formats such as panoramic picture plane size, high-vision picture plane size and standard picture plane size are switched by the rotation of a photometric lens system consisting of one lens 30, so that the photometric sensitivity distribution fit to the photographic format is obtained.

Title: Sliding bearing for high temperature
Inventor: HORIUCHI MASAAKI
IPC: F16C33/12
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To improve the wear resistance of a sliding bearing and to stabilize the coefficient of friction by constituting the sliding bearing used under a high temperature with Ni-Cu alloy having a thin film of NiO on the surface and at the same time coating the surface of sliding bearing with solid lubricant. SOLUTION: The sliding surface of the bearing 1 supporting the rotary shaft 2 for the variable blade 3 of gas turbine operating under a high temperature is coated with solid lubricant such as graphite base carbon or molybdenum disulfide or the like. The sliding bearing 1 is composed of a Ni-Cu alloy comprising 5-40% Cu and the balance Ni, and is heated under a high temperature in an oxidizing atmosphere of the air or the like, and then on its surface a thin film 1a with a thickness of 10-45 μm of NiO as the main component is formed. Even when the solid lubricant is worn out, the existence of NiO prevents the metals of the rotary shaft 2 and the sliding bearing 1 from direct contact, and thus the sliding surface of sliding bearing is free from wearing and seisure and is operated stably.

Title: Reciprocating type electric razor
Inventor: NINOMIYA KAZUNORI
IPC: B26B19/12
Filed: 1977-12-16
Abstract: PURPOSE: To provide the subject razor wherein unnecessary vibrations inherent to the electric  razor are removed to fabricate an efficient structure of driving a movable blade.   
     CONSTITUTION: The movable blade 7 1 , 7 2  slide contacting the outer blade 2 is divided into two,  left and right hands, at the intermediate part in the reciprocating direction. The thus divided  movable blades 7 1  and 7 2  are driven simultaneously on the same straight line P in the opposite  directions. More specifically, when an ellipsoidal cam 14 is rotated, the movable blades 7 1  and 7 2   make reciprocating motions on the same straight line P in left and right, opposite directions at the  amplitude of 1/2 of the difference between the long diameter and short diameter. In this case,  since a coil-shaped resilient member 13 pushes up obliquely movable blades 7 1  and 7 2 , the resilient  member 13 concurrently serves for an operation of press-fitting the movable blades 7 1  and 7 2  to  the outer blade 2 and an operation of a return spring to the inner side of the reciprocating motion.  Since a drive transmitting part 15 abutting the cam 14 is formed into a tapered surface similarly  as the conical tapered surface of the cam 14, the blades do not descend carelessly and the cutting  quality is not lowered because of the variation in the state of press- fitting the outer blade 2.
