Title: Amplifier circuit
Inventor: SANO YOSHIAKI
IPC: H03G1/04
Filed: 1987-12-18
Abstract: PURPOSE:To satisfactorily amplify an input signal even near a maximum allowing input signal level by providing a gain control circuit to variably control the gain of a variable gain amplifier circuit, generating a distortion detecting signal, which expresses the distortion of the output signal of a gain constant amplifier circuit, and variably controlling the gain of the variable gain amplifier circuit based on this distortion detecting signal. CONSTITUTION:A gain control circuit 3 detects a peak value A1 of the output signal of a gain constant amplifier circuit 2, for example. From a detecting reference level L, which is smaller than the detected peak value A=A1 by a prescribed value, and the output signal of the gain constant amplifier circuit 2, a distortion detecting signal DS is generated to express the distortion of the output signal of the gain constant amplifier circuit 2. A control signal generating part 12 converts the distortion detecting signal DS from a node N to a direct current signal to correspond to the change of a pulse width (t) and outputs the signal from a terminal 22 as a control signal. Accordingly, even when a power source voltage +VCC is fluctuated and the peak value is changed, since the reference level L is changed with following this fluctuation, stable circuit operation can be obtained. The output signal of an amplifier circuit can be removed with a constant distorting rate in correspondence to the change of a clip degree.

Title: Stereotactic-guided radiation therapy system
Inventor: MAAKU PII KIYARORU
IPC: A61B6/03
Filed: 1990-11-27
Abstract: PURPOSE: To accurately obtain an isodose contour without modifying the accelerating head of a linear accelerator by passing radiation beams through a variable-length path having a material (fluid) substantially equivalent to the tissue of a patient, before the radiation beams enter the patient. CONSTITUTION: A patient 305 is placed on the rotary bed of a linear accelerator with either a target on the cranium 308 or an obstacle 306 placed at the center of a collimator 304' used for focusing the radiation beams 311 of the linear accelerator. As the collimator 304' moves along a path 308, it increases or decreases its length from a means 315 so that the end of a variable-length path 317 makes contact with the cranium 308 of the patient 305, and then it focuses the radiation beams 311 toward the obstacle 306 via the variable-length path 317 having a material 318 which is equivalent to living tissue. Thus when the collimator rotates around the cranium of the patient, the amount of radiation focused toward the obstacle is held at a fixed value, so that time current linear accelerator can be used without modifying its accelerating head.

Title: Tower-like structure
Inventor: HONDA AKIHIRO
IPC: E04H12/00
Filed: 1993-12-21
Abstract: PURPOSE:To reduce the generation of wind separation flow in a structure and prevent the generation of resultant vibration by installing a stair-like corner cut to four corners of a tower-like structure main body which is substantially square-shaped in cross section. CONSTITUTION:A tower-like structure 1, which is substantially square-shaped is cut off by the length D up to the point (b) at a right angle to each side at the parts of the point (a) in such a fashion that the length B may be left over in the center of each side of sides 1A and 1B and 1C and 1D having the length A before a corner cut 2 is installed. Then, the structure is cut off from the point (b) in parallel to the side, thereby constituting a cut-off portion having the length C and forming the right angle stair-like corner cuts 2. When wind blows against the structure in the direction marked with an arrow, the structure 1 is vibrated in the X to X direction. A fixing eddy is generated at the corners by the corner cuts 2, thereby reducing the release of the eddy by the separation on the after-flow side and the damping force acting on the structure as well.

Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate any necessity of a lot of power at a time and prevent step-out by pre-exciting respective pulse motors in such a state that a time zone of pre-excitation of some pulse motor is not overlapped with that of another pulse motor, after turning on the power of a device. SOLUTION: A paper feed control part 900 for controlling drive of motors M2-5 arranged in a sheet carrier part is constituted of four microcomputers 910, 920, 930, 940 controlled by a program. When a main switch of a copying machine is turned on, one microcomputer 910 outputs pre-exciting command signals to other microcomputers 920, 930, 940 at Ty seconds intervals in order from To seconds after the turning-on and also outputs pre-exciting signals to respective exciting circuits of paper feeder motors M3-1 , M3-2 , M3-3 , M3-4 at Ty intervals for Tt seconds so as to pre-excite them in order. Because time belts of the pre-excitation of the respective motors are mutually shifted, the maximum current value required for the pre-excitation is approximately 2A, which is extremely lower than that of simultaneously pre-exciting all the motors.
