Title: Fmcw radar equipment
Inventor: ASANO KOICHI
IPC: G01S13/34
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide FMCW radar equipment which can detect the distance to and speed of a target by surely detecting a peak pair even when a plurality of targets exists. SOLUTION: A detector 16 generates a beat signal by synthesizing and detecting its transmitted signal frequency modulated with a triangular wave and a received signal reflected from a target. The beat signal is supplied to a signal processor 18 and the processor 18 detects the peaks in the rise and fall phases of the beat signal by analyzing the frequency of the signal. The processor 18 calculates the present distance to and speed of the target from previously detected distances and speeds and, in addition, estimates a peak pair.  When a detected peak pair which is different from the estimated peak pair by a prescribed value or smaller exists, the processor 18 decides the peak pair as the true peak pair and, when the number of detected peaks which are different from the estimated peak pair by the prescribed number or smaller is one, the processor 18 computes the other peak from the estimated value. Then the processor 18 calculates the present distance to and speed of the target from the true peak pair.

Title: Image forming device
Inventor: MURAYAMA HISAO
IPC: G03G15/08
Filed: 1989-03-28
Abstract: PURPOSE:To suppress variation in toner grain diameter and to improve reproducibility concerning fine lines, etc., by recovering residual developer and carrying out replenishing of new toner when remaining quantity of developer in a developing container is detected to be below a fixed value by a remaining quantity detecting means. CONSTITUTION:In the image forming device where the image is formed by an electrophotographic method, as the copying number of pieces increase, the toner of large diameter is eventually accumulated in the developing container 12. Therefore, a torque detecting device is set beforehand to detect when toner residual quantity in the developing container 12 becomes below the fixed quantity, and detecting signal voltage is outputted. When the residual toner is judged to be below the fixed quantity, the toner remaining in the developing container 12 is traveled to a recovering container 15 of a cleaning device 8. If repleshing of new toner is carried out, the diameter of a toner grain in the developing container 12 is prevented from becoming large in diameter in effect, and even with fine line image, image becomes constantly of high quality with good reproducibility.

Title: Vehicular turning device
Inventor: SUGIYAMA MIZUHO
IPC: B60G17/015
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce minimum turning radius with a simplified structure and also make it applicable to general vehicles as well. SOLUTION: Each wheel W position is provided with a hydraulic suspension mechanism 10 including a hydraulic cylinder 11. A microcomputer 20 controls a pressure control valve 12 through respective drive circuits 21 and variably controls oil pressure of the hydraulic cylinder 11. When a vehicle makes a turn, the microcomputer 20 raises the hydraulic cylinder 11 oil pressure corresponding to a front wheel W on the outer side of the turn and lowers the hydraulic cylinder 11 oil pressure corresponding to a front wheel W on the inner side of the turn based on the detection of a steering angle sensor 23. Thus the grounding load of the front W on the outer side of the turn increases and the vehicular minimum turning. radius becomes small by the vehicular turning center displacing to the body side.

Title: Form separating device of electrophotographic copying machine
Inventor: YOSHIZAWA MASATAKA
IPC: G03G15/00
Filed: 1982-05-10
Abstract: PURPOSE:To prevent the absence of a picture at the rear end of transfer paper by setting the separation point of the transfer point within the electrostatic charge area of a transfer corotron and preventing the form from separating from the surface during thick paper transfer until its rear end reaches the separation point. CONSTITUTION:The separation point of the form 14 by a separating means 3 is the side contact A of the separating roll 5 with a separating belt 4 which contacts a photoreceptor 1 in the tangenital direction. The point A moves as shown by an arrow (a) when the separating roll is put closer on the common tangential line between the photoreceptor 1 and separating roll 5, or as shown by an arrow (b) when the roll is put away. For this purpose, the separation point A is set in the electrostatic charge area (slanting-line part) of the transfer corotron and the form 14 is sucked to the surface of the photoreceptor 1 forcibly by electrostatic force until its rear end reaches the point A. Therefore, the rear end of the form never separates from the surface of the photoreceptor 1, so a toner image is transfered to the form 14 up to its rear end securely.

Abstract: PROBLEM TO BE SOLVED: To make combustion vibration due to pressure fluctuation as small as possible by providing a controller section which amplifies an output signal from a central processing device for processing vibration stability according to frequency band of vibration fluctuation analyzed by a frequency analyzer and sends an amplified signal to a fuel valve as a valve open/close signal to implement a control. SOLUTION: Combustion vibration in the process of producing a combustion gas 10 is detected by a pressure sensor 16 installed in a combustion zone of a combustor inner cylinder 12 and a signal is applied to a vibration suppression controlling section 18. A central processing device 20 uses frequency band analyzed by a frequency analyzer 19 to calculate the position of a current vibration mode. According to this calculation, fuel air ratio is determined and an output signal is amplified by a voltage amplifier 21 and is inputted to a controller section 22 as an open/close signal for a fuel valve 8. The fuel valve 8 is controlled to be opened or closed in such a manner as to lower intensity level of combustion vibration so that fuel supplied to an fuel injection section 13 is adjusted to increase or decrease.  Since the fuel air ratio is automatically controlled, vibration is suppressed low.
