Title: Scanning optical system
Inventor: KUBOTA KEIICHI
IPC: G02B27/00
Filed: 1979-09-18
Abstract: PURPOSE: To enhance resolving power by providing an optical scanning means scanning the light beam from a monochromatic light source on the exit side of the light source and providing a one-dimensional stripe-shaped grating converting the light beam to an elliptical beam between the monochromatic light source and the optical scanning means.  
     CONSTITUTION: The laser light 22 out from a laser light source 21 is coverted to a light beam 24 of an elliptical shape by a beam coverter 23, and becomes the light beam 27 further magnified by lenses 25, 26. After the light beam 27 is reflected by a scanning mirror 28, it is made to the beam 31 focused on the scanning plane 30 existing on the (xy) plane by an f.θ lens 29. The focused beam 31 is scanned in the (x) direction by rotating the scanning mirrror 28 within the (xz) plane and every time when the (x) direction scanning ends, the scanning plane 30 successively moves in the (y) direction. The light reflected from the scanning plane 30 is detected with a detector 32, whereby two-dimensional scanning is accomplished. As the light beam converter 23, a phase grating of a stripe shape is used. Thereby, the resolving power may be enhanced.

Title: Automatic combustion controlling method for incinerator
Inventor: ISHIDA TAKASHIGE
IPC: F23G5/50
Filed: 1982-07-09
Abstract: PURPOSE:To keep the combustion efficiency always at a high level, by detecting the types of refuse through detection of the long-period varying wave form of the temperature of exhaust gas, detecting abnormality in the combustion-air feed rate through detection of the short-period varying wave form, and adjusting the refuse feed rate or the air supply rate on the basis of the detected output signals. CONSTITUTION:A temperature detector 2 is disposed at a proper position of an smoke discharge opening of an incinerator 1 for measuring the temperature of exhaust gas, and the varying wave form of the temperature of exhaust gas is recorded by an exhaust-gas temperature recorder. Then, it is inputted to a varying wave form divider for analyzing the wave form into the long-period varying component and the short- period varying component, and these two components are afforded to a refuse controlling means and an air-flow controlling means. When the long-period varying wave form is changed abnormally, it is detected immediately by the refuse controlling means and adjustment is made on the refuse feed rate (and/or refuse feeding speed). On the other hand, if the short-period varying wave form is changed abnormally, it is detected immediately by the air-flow controlling means and adjustment is made on the air supply rate, whereby abnormal combustion due to the air supply rate can be removed.

Title: Drive circuit for normal and reverse rotation of motor
Inventor: ONO NAOKI
IPC: H02P1/22
Filed: 1988-05-19
Abstract: PURPOSE:To acquire step-up function in a simple circuit constitution by providing a step-up circuit composed of diodes and capacitors connected inseries. CONSTITUTION:When a power terminal T1 is turned ON, the charge current flows to step-up circuits 6a and 6b respectively through diodes D1 and D2, capacitors C1 and C2 and resistances R1 and R2, with which the capacitors C1 and C2 are charged up to the upper voltage (VDD). Then, when transistors Q1 or Q2 is turned ON, a point of contact N1 or N2 gets to power potential. The cathode side potential of the diode D1 or D2 thereby becomes the potential of 2VDD, so that the gate potential of the transistor Q1 or Q2 can be raised higher than the power potential VDD. In this way, the step-up function can be acquired in a simple circuit constitution.

Title: Automatic focus controller of microscope
Inventor: MAKIHIRA HIROSHI
IPC: G02B21/26
Filed: 1986-05-28
Abstract: PURPOSE:To enable focusing even when a sample surface shifts out of a defocusing detectable area by performing focus adjustment control by using a defocusing signal obtained from light-dark information in the defocusing detectable area or the stored value of a defocusing signal right before the sample surface shifts out of the detectable area when so. CONSTITUTION:The pattern of a stripe pattern mask 2 is projected on the sample 4 through a half-mirror 8 and an objective 3 by using illumination light from the light source 1 of a microscope part 10. The image of the pattern is picked up by image sensors 11 and 12 through the objective 3 and half-mirrors 8-10. A decision circuit 21 decides the direction of defocusing from the signals of the sensors and generates a decision signal 42 for the defocusing detectable area A, and when the sample surface is in the area, a storage circuit 22 stores the decision signal and generates an automatic focusing operation ready signal 43. This signal 43 is used to control the focusing through a piezoelectric driver. If the sample surface shifts out of the area A, the focusing operation is carried on by using the defocusing signal stored in the storage circuit 23.

Filed: 1989-05-15
Abstract: PURPOSE:To obtain excellent picture quality at reproduction by eliminating emphasized high frequency noise signal component in the case of the application of nonlinear emphasis and video emphasis processing to a luminance signal. CONSTITUTION:A video input signal is fed to a low pass filter (LPF) 11 and a separated luminance signal Y is subject to sequential emphasis by a nonlinear emphasis circuit 13 and a video emphasis circuit 14.

Title: Error correction decoder
Inventor: FURUYA YUKITSUNA
IPC: H03M13/23
Filed: 1984-06-13
Abstract: PURPOSE:To obtain an error correction decoder detecting an error not corrected when the error takes place on a transmission line by deciding it as detection of an error when an output of a merge detecting circuit shows non-merge and extracting a decoded output from the final stage of a path memory. CONSTITUTION:The path memory of a merge detecting circuit 405 stores a path connected in 4 ways of states (0, 0), (0, 1), (0, 1) and (1, 1). The path information corresponding to each state at the final stage is inputted respectively from terminals 500, 501, 502 and 503. When merge takes place, since the path after merge with respect to all states is the same, the input from the terminals 500, 501, 502 and 503 is all identical. Thus, the merge detection circuit 405 has only to detect whether the four inputs are all identical or not. An output of an exlcusive OR 506 goes to logical ''0'' when merge takes place and goes to logical ''1'' when no merge occurs, which allows merge detection. An error is detected through the detection of merge.
