Filed: 1990-03-09
Abstract: PURPOSE:To enable fast, highly accurate pattern recognition even in case of a relative position shift by comparing a reference pattern which is provided with a blind a area and a reference pattern obtained by moving the reference pattern in parallel and calculating their correlation value. CONSTITUTION:A comparing means 14 compares picture element data of a 2nd reference pattern formed by providing the blind area nearby the contour of a reference pattern stored in a 1st storage means 16, picture element data of a 3rd reference pattern formed by moving a reference pattern stored in 2nd storage means 18 and 20 by specific picture elements in parallel, and picture element data of an input image pattern. At this time, picture element data corresponding to the blind area are not compared. Consequently, the input image pattern of a figure, etc., can be recognized fast automatically with ease, a wide permissible range is obtained for the position shift of the input image pattern, and the pattern recognition which is extremely high in recognition accuracy becomes possible.

IPC: H03F3/34
Filed: 1991-03-22
Abstract: PURPOSE:To improve the high frequency characteristic by connecting a current source to a noninverting output terminal of an amplifier via a constant voltage circuit. CONSTITUTION:A signal inputted to an information 2 of a DC amplifier 1 is amplified by the DC amplifier 1, a noninverting signal is outputted to an output terminal 14 through a low impedance converter 5 and a constant voltage circuit 7 and an inverting signal is outputted to an output terminal 13 through a low impedance converter 6 and a resistor 8. A DC amplifier 12 connecting to a control terminal 11 of a current source 10 and the output terminals 13, 14 is operated in a way that a current of the current source 10 is increased when a voltage at the output terminal 13 rises thereby decreasing the voltage of the output terminal 13 and the reverse operation to above is implemented when the voltage at the output terminal 13 decreases. That is, the amplifier circuit is operated by making an offset voltage at the output terminal 13 equal to that at the output terminal 14. Moreover, the effect of an AC signal onto the operation of the DC amplifier 12 is prevented.

Title: Start safety device for hydraulic closed circuit
Inventor: OSHINA MORIO
IPC: F16H61/40
Filed: 1989-03-10
Abstract: PURPOSE:To prevent an oil hydraulic motor from being driven following a prime mover even when it is restarted with a variable displacement oil hydraulic pump still having a certain delivery capacity by providing a valve control means setting a valve means to the first position, while at least the prime mover is in starting, and to the second position after the prime mover is started. CONSTITUTION:By closing a starter switch 2, power is fed from a delay circuit 32 to a solenoid part of an opening and closing valve 31 selected to a position (m). At very low temperature time, low viscosity of oil causes a tilt cylinder 16 to be reset not immediately to a neutral position, sometimes an oil hydraulic pump 11 is placed in a tilt angle not zero. In this case, the oil hydraulic pump 11 delivers oil, for instance, to a main pipe line 17A by restarting an engine 6, but here because the main pipe line 17A is connected by a valve 31 to a pipe line 15B, it allows the oil to flow in a cylinder chamber 16b displacing a piston 16c in a direction to a neutral position, and a pressure is decreased in the main pipe line 17A by reducing a delivery amount of the pump 11. Accordingly, an oil hydraulic motor 18 is prevented from rotating.

Title: Lens barrel capable of focusing automatically and manually
Inventor: ANDOU MAKOTO
IPC: G03B13/36
Filed: 1982-04-08
Abstract: PURPOSE:To make an operation simple and quick by connecting an operation ring provided on a stationary barrel and a driven member for automatic focusing for a camera body side respectively transmittably on a turning member which accomplishes focusing by turning around the optical axis. CONSTITUTION:While a driven shaft 15 is in the position where it cannot engage a driving shaft 13, an engaging arm 48b rides on a driven part 46b and engages the same frictionally, when an operating ring 38 is in a manual focusing position. Therefore, a rotating cylinder 30 can be driven only by the power transmitted from the ring 38 by the frictional engagement, and the focusing is operated manually by the ring 38. However, the rotation of a rotary barrel 30, etc. is transmitted up to the sahft 15 but is not transmitted to the shaft 13; therefore, no resistance is generated in operating the ring 38, and the changing over between the automatic focusing state and the manual focusing state is accomplished on the spot simply by moving the ring 38 in the optical axis direction.

Title: Method of measuring absolute humidity of air
Inventor: MITTER HELMUT
IPC: G01N27/22
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To perform a stable measurement for a long period even near a dew condensation by using a capacitive sensor and a temperature sensor, and changing the temperature of the capacitive sensor by a heating element when the humidity reaches a prescribed humidity limit value to measure the absolute humidity. SOLUTION: A capacitive humidity sensor 1 and a resistance temperature probe 2 are provided on a heat conductive electric insulating carrier 3, and its output signal is transmitted to sensor interfaces 9, 10 through a conductive wire 8, converted into a measured value proportional to the sensor capacity Cs and the sensor temperature Ts, and inputted to a control unit 11. The evaluating circuit of the control unit 1 calculates the measured value of relative humidity from the input signal, and a current proportional to the measured value is carried to an output signal interface 12.  The relative humidity is measured at a fixed temperature up to a preset limit value of, for example, 75%, but when the relative humidity is increased over this value, the control unit 11 increases the operating current Is of the temperature sensor 2 to heat the temperature sensor 2 to the temperature Ts higher than room temperature. Consequently, water can be prevented from being condensed on the humidity sensor 1 even near a dew point, and the absolute humidity can be precisely measured even in a high humidity range.
