Title: Camera
Inventor: NAKANISHI KAZUHIRO
IPC: G03B1/12
Filed: 1985-08-20
Abstract: PURPOSE:To switch three driving systems securely with simple, compact structure by switching a film winding/rewinding mechanism which is coupled with a motor gear and a lens driving mechanism by two clutches and a slide plate. CONSTITUTION:A gear 6 is rotated counterclockwise by the counterclockwise rotation of a motor gear 1 through a unidirectional clutch 7 to wind a film. Gears 5 and 17 mesh with each other by the clockwise rotation of gears 1 and 3 through the clutch operation of a lever 4 to rewind the film. Gears 15 and 16 engage each other by the clockwise rotation of the gear 1 and the counterclockwise rotation of a gear 13 through the clutch operation of a lever 14 to move the focus of a lens. The slide plate 21 is moved right and left to engage its projection 21b or 21d with the pin 4a or 14a of a lever, thereby locking the motion of the lever 4 or 14. Thus, motor driving force is switched and transmitted to three driving systems freely through the simple mechanism.

Title: Optical fiber ferrule terminal
Inventor: KATO KUNIHARU
IPC: G02B6/36
Filed: 1990-07-13
Abstract: PURPOSE:To prevent loss fluctuation from occurring even when ambient temperature changes by setting the length in the optical axis direction of the optical fiber insertion hole of a ferrule larger than that in the optical axis direction of a core expanding area including the core diameter transition area of an optical fiber. CONSTITUTION:The length in the optical axis direction of the optical fiber insertion hole 32a of the ferrule 3a provided with an inside diameter that nearly coincides with the outside diameter of the optical fiber is set larger than that in the optical axis direction of the core expanding area including the core diameter transition area 12 of the optical fiber 1 setting a terminating plane 31a in which an end face is terminated with the ferrule 3a as an origin. Thereby, since the core diameter transition area 12 in which mode field conversion occurs is enclosed with extremely thin adhesive 5, it is hard to apply nonuniform stress to the core diameter transition area 12 even when the whole optical fiber ferrule terminal receives the change of the ambient temperature, which allows radiation loss due to micro irregular bending i.e. micro bending loss hardly to occur.

Title: Protecting cover for lamp
Inventor: TAKAMI SEIICHIRO
IPC: F21V15/00
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent a crude gas from being ignited and being slightly exploded at lighting and stabilize it by forming a protecting cover by use of a metal thin plate cylinder having a number of holes on the circumferential wall. SOLUTION: A protecting cover 1 is formed of a steel plate having a number of small holes 1a equally bored by punching in a thin stainless steel plate, which is formed into cylinder. The light from a mantle forms a settled moody brightness by the small holes 1a provided on the protecting cover 1. Since the protecting cover 1 is permeable by the small holes 1a, a small explosion that a crude gas is stayed and ignited within the protecting cover 1 is never caused. When the porosity is 60% or more, for example, as a metal mesh, a turbulent flow is caused by the effect of wind so that a stable brightness can not be provided, and the mantle is also broken. Further, since the brightness is reduced when the porosity is smaller than 30%, a porosity of 30-60% is preferable.

Filed: 1991-07-24
Abstract: PURPOSE:To provide the waveguide type optical parts having small propagation losses. CONSTITUTION:A lower clad layer 2 consisting of quartz glass is formed on a substrate 1. An antistatic layer and a mask layer having desired patterns are formed in this order on the surface of a lower clad part 2 and are irradiated with an electron beam from above the mask layer to form core parts 6 of desired patterns within the lower clad layer 2.
