IPC: H04B10/29
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To reduce the polarization dependence of an input light signal in a light separation circuit performing the signal separation of a light domain by a four light wave mix.

Title: Shutter control system of ccd
Inventor: KIMURA ISAKU
IPC: H04N5/351
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To control a shutter without noise at high speed by neglecting a prescribed condition in the read period of non-displayed pixels so as to shorten intervals between discharge signals. SOLUTION: Supposing that the number of all the pixels is 500,000, for example, the number of effective pixels is made 450,000 and 330,000 pixels among them are displayed. Consequently, effective pixels excepting for a displayed pixel area and pixels in a part (black level) on the outside of it become non- displayed pixels and never appear in a picture actually. In the part of these non-displayed pixels, there is no problem even if noise is included in the electric charge by a discharge signal (SUB signal).  Then, during transferring the displayed pixels as shown in the Figure, the discharge signal is outputted under a prescribed condition but in the transferring period of the non-displayed pixels after reading the displayed pixels on the other hand, the intervals between the discharge signals are narrowed by neglecting the prescribed condition to realize a very fast shutter and control. There is no restriction on the timing of the discharge signals at this time.

Filed: 1980-04-30
Abstract: PURPOSE:To enable to select a mode optimum for processing easily during processing by mounting a throttling mechanism changing an effective inner diameter of a laser tube at least one place of the laser tube. CONSTITUTION:Throttling blades 101a, 101b divided into plural pieces are pushed against a central section by means of springs 102.

A gas laser is oscillated by a basic mode under a condition that the blades 101a, 101b are throttled. The gas laser, on the other hand, is oscillated by a multi-mode under a condition that the blades 101a, 101b are opened. Thus, uniform irradiation ranging over a wide area and focussing irradiation to a point can easily be changed over instantaneously in an oscillator, and special materials such as ceramics can be processed.

Filed: 1990-03-08
Abstract: PURPOSE:To transmit a serial signal SS only for two consecutive frame transmis sion end signals FE are inputted through the reception of a timing signal and to reduce the cost by generating a 1-frame transmission end signal FE for each frame end of a serial signal SS-generated continuously. CONSTITUTION:A serial signal transmission section 11 sends a continuous serial signal SS and a 1-frame transmission end signal FE for each end of frame based on an output of an oscillator 10. Upon the receipt of a timing signal from a timing generating circuit 12, a control circuit 13 generates a control pulse for a period of 1-frame inputted by a succeeding FE from the point of time of the input of the signal FE from the transmission section 11 just after the input of the timing signal. A gate circuit 14 extracts the signal SS, for one frame period only for the received control pulse period and sends the extracted signal. Thus, even when the timing signal and the signal SS are a synchronous, the signal SS is extracted without use of a CPU, the cost of software is reduced and simple and small sized circuit constitution is attained.
