Title: Optical device
Inventor: DEMURA TAKESHI
IPC: G02B7/08
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent a motor and a power transmission part from being damaged and precisely detect an optical means reaching an operation end by providing an end detecting means which detects the optical means reaching the end part according to the output of a movement quantity detecting means. SOLUTION: A lens group 1 is driven in a specific direction before the lens group 1 is controlled by a motor 5, e.g. when electric power is fed from a power source input means provided to a lens barrel. A lens driving ring 21 has its operation range restricted by a stopper member 23, so the output signal of an encoder 24 stops varying at the moment the lens group 1 stops at the operation end. Then when a state wherein the output signal of the encoder 24 does not vary although a driving command is supplied to the ultrasonic motor 5 is detected for a specific time, an end detecting means in a CPU judges that the lens has reached the operation end (end part). At this time, a reference position setting means in the CPU clears a position counter for lens control and sets an origin of control (reference position).

IPC: H04N5/235
Filed: 1989-12-29
Abstract: PURPOSE:To automate the a flood lighting means and to improve operation convenience by providing the video camera with the lighting means to be turned on and off and controlling the lighting means so that the means is turned on when the value of an incident light signal is less than a previously determined 1st value and turned off when the signal value is larger than a previously determined 2nd value. CONSTITUTION:An iris circuit 28 drives an iris meter 10 in response to the output of a sampling/holding circuit 30 to control the light quantity of incident light upon an optical system 12. An AGC circuit 36 automatically controls the gain of the inputted signal and outputs the gain-controlled signal to a video signal processing circuit 18 and a light control circuit 24. Thereby, a movie light 26 lights up when the fixed quantity of incident light corresponding to a low level is dropped during the period of image recording. When the image recording is finished or a subject is gradually goes to bright in accordance with the increment of incident light exceeding the fixed quantity corresponding to a mid-level, the light 26 is automatically turned off. Thereby, the operability of the light can be sharply improved as compared with manual operation.

Title: Production of laminar type diffraction grating
Inventor: NAGANO TETSUYA
IPC: G02B5/18
Filed: 1991-11-28
Abstract: PURPOSE:To enhance the perpendicularity of both sides of grating grooves so as to eliminate the roughening of groove bottoms and to obtain the smooth groove bottoms by mixing Ar in reactive ion beam etching using a hydrocarbon fluoride. CONSTITUTION:An inorg. material consisting essentially of SiO2 is used for a grating blank material 1 and the diffraction grating patterns consisting of a photoresist layer 2 are formed thereon. The grating element material 1 surface is subjected to the ion beam etching from the direction perpendicular thereto by using gases formed by mixing the Ar with the hydrocarbon fluoride, by which the grating grooves are formed. The etching rate ratio of the inorg. material of the SiO2 to the resist layer 2 increases relatively if the hydrocarbon fluoride is used as the reactive gas for the reactive ion beam etching, but the etching rate of the resist is decreased by mixing the Ar with this gas. The etching rate ratio is thereby additionally increased. The deposited carbon generated in the case of the hydrocarbon fluoride alone is removed by mixing the Ar therewith.
