Title: Power steering device
Inventor: KOMAMURA SEIJI
IPC: B62D5/08
Filed: 1985-04-25
Abstract: PURPOSE:To aim at miniaturizing a power steering device, by displacing the fulcrum point of a control lever in its swinging direction or the direction opposite to the former, in accordance with the running conditions including the speed and steered angle of a vehicle, etc. thereby it is possible to eliminate the necessity of a hydraulic reaction mechanism provided at each end of a spool in selector valve. CONSTITUTION:When a steering wheel (not shown) is rotated so that a pinion shaft 15 rotates associatingly, the pinion shaft 15 swings due to the change-over resistance obtained at this time. This swing causes a control level (a) having its acting section 13 inserted in a communication hole 12 in a spool 2 in a control valve V to swing between the acting section 13 and a circular force point section 14 about a rod-like fulcrum section 14, as a center point, which is positioned on the opposite side, thereby the spool 2 is changed over in the swinging direction. In this arrangement, when a controller 25 changes over a selector valve 27 in accordance with the running conditions of the vehicle to introduce pressure oil from a pump P into a pressure chamber 18 or 19, a piston 20 is displaced, and therefore, the fulcrum point section 16 is shifted. Then, the fulcrum point of the control lever (a) is displaced to adjust the operating force of the steering wheel.

Filed: 1986-04-18
Abstract: PURPOSE:To obtian an excellent picture quality without attending a remarkable design change such as a monitor by using twice a video signal by 1/2 picture obtained from a multiplexed video signal so as to form a video signal whose vertical frequency is doubled. CONSTITUTION:A split synthesizing circuit 3 splits pictures 1a, 2a from video cameras 1, 2 respectively, combines the center half of both the pictures, a video signal S3 forming a combined picture 3a is fed to a coding circuit 4 and a digital video signal subjected to band compression is sent to a line 5. A digital video signal S3' is restored by a decoding circuit 6 at the recetion side, a split circuit 7 separates video signals corresponding to the upper half and the lower half region of the picture 3a from the video signal S3', uses each of the video signals by a half picture twice to double the vertical frequency only without changing the signal band width and the horizontal frequency thereby applying the processing doubling equivalently the field frequency. Only the center half of the display picture of monitors 8, 9 is scanned repetitively twice each and the video image with unremarkable flicker is obtained.

Title: Inductive communication line
IPC: H04B5/00
Filed: 1992-03-13
Abstract: PURPOSE:To reduce the total size of a transmitting device without causing any line resonance by forming each unit element with the combination of a lead wire of a prescribed electric constant which can resonate by the frequency of the communication signal and a capacitor. CONSTITUTION:A inductive communication line 10 consists of the lead wire parts L (L1, L2...Ln) of the prescribed length and the corresponding capacitors C (C1, C2...Cn) which are alternately connected to each other. Then the same resonance frequency is set for all unit elements U and also coincident with the frequency of the high frequency signal used for the information communication in regard of each resonance frequency of the parts L and the capacitors C combined into the elements U. Therefore a large current flows even with a compact transmitting device when the inductive communication signals are supplied from the input terminals INa and INb. Thus an intensive signal magnetic flux M is secured and the communication S/N is improved.

Title: Method of counting number of passengers
Inventor: TSUBOTA NAOKI
IPC: G07C9/00
Filed: 1978-07-21
Abstract: PURPOSE:To measure the number of the persons of object who pass highly accurate, by selecting the persons by the size of their stature by intercepting a photo- loop between a projector and a light receiver by their shoulder or head. CONSTITUTION:A cross portion E1 of luminous flux C1 from a projector A1 of infrared rays, etc. and an extension course D1 of a photo-entry course of a light receiver B1 is formed by arranging the projector and the light receiver in shapes that face in the oblique direction from an upper portion of an inlet with width, in which one adult can pass, of a building. The cross portion E1 is set so that the lower end reach a floor surface F and the upper end be located at portions parting from the floor surface by approximate 120cm, and a photo-loop is produced between the projector A1 and the light receiver B1. Thus, the loop is intercepted and a counter counts by one because the shoulder or head of an adult interrupts either of the two or both of the luminous flux C1 or the extension course D1 when the adult approaches to a vertex of the cross portion E1, but the counter does not count when a child with stature not more than 100cm comes. Consequently, the number, etc. only of adults who pass or enter are accurately measured while this method can be applied for other objects.

Title: D/a converter
Inventor: YAMAMURA TAKESHI
IPC: H03M3/02
Filed: 1994-04-27
Abstract: PURPOSE:To suppress an undesired tone component and a high frequency noise component by changing a reference analog signal of an analog filter when a non-signal input detection means detects a non-signal state. CONSTITUTION:When usual digital data are given to a digital filter 10, an output of a non-signal input detection circuit 40 is logical 0 and a prescribed reference DC voltage is fed to an analog filter 30 as a 1st analog signal. On the other hand, a zero code (each of parallel n-bits is all zero) is detected at least over an M-clock period, since the output of the circuit 40 transits from logic 0 to logic 1, the 1st analog signal changes to 0 (ground level). Then the 1st analog signal being an output of an analog signal setting circuit 50 is sequentially incremented/decremented according to a logic level or the polarity of a 2nd digital signal of a noise shaper 20 to form the 2nd analog signal. Thus, a tone component or a high frequency noise component is suppressed from the noise shaper 20.

Title: Starter for internal combustion engine
Inventor: KAJIYOSHI SHUSUKE
IPC: F02N5/02
Filed: 1988-04-14
Abstract: PURPOSE:To easily rotate a starting member side of a starter under a small force so as to store a force by shutting off the coupling between the starting member side including a rope pulley or the like and a crank shaft during storage of force by a spring so as to allow only a force for urging the spring to act upon the starting member side. CONSTITUTION:Upon start of an internal combustion engine, when an operator holds a grip at the free end of a rope 14 and quickly pulls the rope 14 outward, a rope pulley 10 is rotated. At this time, the stored force of a spiral spring 18 is gradually increased, but the stored force of the rope pulley 10 is relatively low since the drive coupling between a crankshaft 5 and the pulley 10 is cut off by one-clutch device (21, 22). Thereafter, when the grip 17 is released, the rope pulley 10 is reversed rapidly by the stored force of the spiral spring 18, and accordingly, the crankshaft 5 is rotated through a ratchet wheel 22, a ratchet 21 and a disc member 19, thereby it is possible to start the engine.

Title: Polarized fluorescent light photometer
Inventor: TAKAHATA FUJIYA
IPC: G01N21/64
Filed: 1983-05-25
Abstract: PURPOSE:To enable the accurate measurement of a polarized fluorescent light even when an organism sample whose suspension particles are easy to precipitate is measured, by operating an agitating means synchronously with the rotation of a fluorescence-side polarizer so as to agitate the sample for a short time. CONSTITUTION:An agitating rod 15 for agitating a sample solution in a cuvette 4 is rotated by an agitator 10 which is controlled by a driving-system controller 11. A fluorescence generated by applying a polarized excitation light to the cuvette 4 is separated into a polarized component parallel to the excitation light and a polarized component vertical thereto by rotating a fluorescence-side polarizer 5 reciprocally and intermittently. The quantity of light of each polarized component is transduced into an amount of an electric signal for data processing. Since an operation of switching the direction of a plane of polarization of the fluorescence-side polarizer 5 is synchronized with an agitating operation in this case, the data processing can be performed efficiently without reducing a time required for taking data. In addition, the sample solution is maintained constantly in a uniform state, since the agitation is conducted frequently, and thus an accuracy of the analysis is improved.
