IPC: H04B10/564
Filed: 1989-04-10
Abstract: PURPOSE:To simplify the constitution of a variable gain amplifier by adding a fixed attenuator, a switching comparator, an attenuator and a switch drive circuit. CONSTITUTION:Since 1st-4th switches 4a-4d are turned off when the relative attenuation of the optical input signal is small, the signal enters a variable gain amplifier 1 and is outputted via a detector 2. Part of the output is fed back to the amplifier 1 via a gain control circuit 3 and an attenuator 8 to control the output constant. Moreover, part of an AGC voltage enters a comparator 6, where the voltage is compared with a threshold level Vh and when the voltage is less than the voltage Vh, the switches 4a-4d are turned off through a switch drive circuit 7 and when the voltage is more than the Vh, they are turned on. Moreover, when the voltage is less than Vh, the subtraction voltage of the subtractor 8 is zero and when the voltage is more than the Vh, the subtraction voltage is A0.

Filed: 1994-04-06
Abstract: PURPOSE:To provide the control system for servo motor with which the vibration of a controlled system can be suppressed and input follow-up ability can be improved by extending the band of a speed loop. CONSTITUTION:Concerning the control of the controlled system due to a servo motor, an acceleration loop is formed by feeding the acceleration of the controlled system back to the torque command of the servo motor. Concerning that acceleration loop, a control term H(s) is contained serially with a term G(s) of the controlled system at a gap from the torque command of the servo motor to the output of the acceleration loop, and this control term is defined as a function for the term of the controlled system and the desired characteristic of the acceleration loop. Further, that desired output characteristic is decided so as not to generate any vibration. Thus, the vibration of the controlled system is suppressed by preventing the output of the acceleration loop from being vibrated.

Title: Three-dimensional display device
Inventor: KENMOCHI NOBUHIKO
IPC: H04N13/04
Filed: 1990-04-05
Abstract: PURPOSE:To reduce the occurrence of malaise, incongruity, and fatigue, etc., even when distance is expressed based on the parallax effect of eyes by providing a mechanism to vary the focal position of an eyepiece. CONSTITUTION:The eyes 1 observe the virtual image 4 of an image display panel 3 image-formed by the eyepiece 5. At this time, the feeling position of an image generated by the parallax effects of the eyes is located at a point A that is the intersection of the eyes. However, since the feeling position of the image generated by the focal point adjusting function of the eyes is located at a point B, difference between the points A and B generates the malaise. Therefore, it is possible to image-form the position of the virtual image 4 at the same position as that of a remarking point in the image being displayed on the image display panel 3 by employing the eyepiece 5 whose focal position can be varied by an actuator 6, etc. In such a way, the occurrence of the malaise, the incongruity, and the fatigue, etc., can be reduced.

Title: Floating membrane
Inventor: NAKAGAWA TAKESHI
IPC: G01N27/12
Filed: 1995-03-24
Abstract: PURPOSE: To contrive an increase in the area of a floating membrane and the improvement of the breaking resistance of the membrane. CONSTITUTION: In a floating membrane 1 with beams 4 provided radially at the four corners of a rectangle on an Si substrate 3, the peripheral parts of the membrane 1 are formed of a silicon oxide (SiO2 ) film in the same way as the beams 4 and the center part of the membrane 1 is formed of an Si3 N4 film 2. When the center part of the membrane 1 is previously substituted for the film 2, an internal stress is offset and the membrane 1 can be prevented from being broken. Or when a group V element, such as phosphorus (P), is added to the SiO2 film forming the membrane 1, noncrosslinkable oxygen is produced in the SiO2 film and as the Young's modular of the SiO2 film is reduced the internal stress can be made lower than a breaking stress at 0.4 to 3.0wt.% of the addition amount of the group V element.  As this result, an increase in the area of the membrane becomes possible to a 400μm angle or thereabouts and a high-sensitivity and high-resolving power thermal sensor can be realized.
