Title: Rotary drum of single-shaft type focal plane shutter
Inventor: ISHII HARUO
IPC: G03B9/28
Filed: 1979-05-25
Abstract: PURPOSE: To miniaturize the diameters of front-curtain- and rear-curtain drums and achieve the smaller size and higher function of the camera by rotatably providing an engaging ring having the protrusions making rotation engagement respectively with the protrusions provided to the front-curtain- and rear-curtain drums on a common shaft.  
     CONSTITUTION: Protrusions 5a are provided to the top and bottom of the engaging ring 5 making free engagement with a shaft 3. The upper protrusion 5a opposes to the downward protrusion 1a of the front-curtain drum 1 and the lower protrusion 5a of the ring 5 to the upper protrusion 6a of the rear-curtain drum 6 respectively. Here, when the drum 1 is rotated counterclockwise by means of a gear 4, the protrusion 1a pushes the upper protrusion 5a of the ring 5, causing the ring 5 to rotate counterclockwise as well. The lower protrusion 5a pushes the protrusion 6a and is detained by a lever 4c and lever 7, causing the drum 1 and drum 7 to be wound. When this engagement is released after this, these are rewound respectively at the rotating angle of about 600°. This angle is the rotating angle twice that of conventional ones and this enables the reduction by half of the drum diameter and the miniaturization of the camera.

IPC: H01L31/10
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent electrons or holes from being trapped by carriers in a light receiving layer and to increase energy conversion efficiency of the light receiving device, by laminating an n-type group III nitride semiconductor layer, a light receiving layer made of an undoped InXGa1-XN, and a p-type group III nitride semiconductor layer. SOLUTION: A light receiving device 1 has a structure, in which a buffer layer 11, an n-type group III nitride semiconductor layer 12, a light receiving layer 13, a p-type nitride semiconductor layer 14 are sequentially laminated on a sapphire substrate 10. The light receiving layer 13 is made of an un-doped InXGa1-XN (0<X<1). The undoped InXGa1-XN is an n-type in an un-doped state, but the carrier electrons in the light receiving layer 13 are minority. Therefore, among holes generated in the light receiving layer 13 through the irradiation of light, number of holes trapped by the carrier electrons in the light receiving layer 13 is small. Therefore, this suppresses loss of the number of holes moving to the p-layer 14 from the light receiving layer 13, thereby increasing the energy conversion efficiency of the light receiving device.
