Abstract: PROBLEM TO BE SOLVED: To provide an information processor capable of easily grasping the general situation of action on a working space. SOLUTION: User's operation on a working space is inputted from an operation information input means 1 and the state of the working space is changed by a working space state changing means 2. When the state of the working space is changed, a state information generation means 3 generates state information indicating the state of the working space and supplies and stores the generated state information to/in a state information storing means 4. A state information extraction means 6 acquires condition information indicating a condition for generating history required by a user through a condition information input means 5 and acquires state information coincident with the condition information from the means 4. A history display means 7 displays the state information acquired by the means 6 in accordance with a specified display format as history.  When specification information for specifying a prescribed display element of the history is inputted from a specification information input means 8, an acquisition means 9 acquires corresponding state information from the means 4 and a working space display means 10 displays a corresponding working space.

Title: Device for adjusting automatically contrast of video signal
Inventor: HIRATA YOSHIHIRO
IPC: H04N5/57
Filed: 1985-03-28
Abstract: PURPOSE:To make it possible to keep the contrast and the brightness of a video signal regardless of the thickness of a sample by constituting a device to correct a reference voltage according to the intensity of a signal within one frame period. CONSTITUTION:An updown counter 11 counts a clock only for the period when a vertical blanking signal drops to '0'. And a circuit that consists of a comparison circuit 10, the updown counter 11 and a D/A converter 13 executes a negative feedback control so that the output of the D/A converter 13 becomes to be equal to the output of a subtraction circuit 9. For example, when the amplitude of a video signal is smaller, the integral output Vi of an integrating circuit 7 is also smaller but, at such a time, it becomes larger because the output (Ec-Vi) of the subtraction circuit 9 is smaller. When the output of the subtraction circuit 9 becomes larger, a negative feedback control circuit makes the output of the D/A converter 13 larger and makes it equal to (Ec-Vi). On the other hand, when the amplitude of the video signal is larger, the output of the integrating circuit 7 is also larger but, in this case, the output (Ec-Vi) of the subtraction circuit 9 becomes smaller because the Vi is larger.

Filed: 1983-04-18
Abstract: PURPOSE:To prevent a crosstalk caused by a wavelength shift by forming two beams of polarized light orthogonal to each other by other converting element, even if light passing through an element for converting an incident light to polarized light orthogonal to each other becomes light beams which are not orthogonal to each other by following a wavelength shift. CONSTITUTION:Linear polarized light which is made incident to a Faraday rotor 1 is set as a point A on the equator of a Poincare sphere. When an optical wavelength is lambda0, the point A rotates by +90 deg. or -90 deg. around an axis passing through the South Pole and the North Pole by the Faraday rotor 1, and moves to a point P1 or P2. The point P1 or P2 is expanded on the equator in case when there is a shift in the the wavelength of light. When the wavelength of light is shifted to a short wavelength side, said point moves to points P'1, P'2. Also, when said point rotates by +90 deg. or -90 deg. around an axis passing through the points P1, P2 by using an electro-optic element 4 serving as the second polarized state converting element, the point P'1 and the point P'2 move to a point P'3 and a point P'4, respectively, and as a result, P'3 and P'4 becomes points roughly opposite to each other with respect to the center 0 of a sphere on the Poincare sphere. In this way, polarized light corresponding to the point P'3 and polarized light corresponding to the point P'4 are orthogonal to each other.
