Title: Fuel injection quantity controller for internal combustion engine
Inventor: INAGAKI HIROSHI
IPC: F02D45/00
Filed: 1990-11-22
Abstract: PURPOSE:To improve the fuel injection control performance by compensating for a stationary deviation attributable to the flow delay of the exhaust gas and the detection delay of an air-fuel ratio sensor itself. CONSTITUTION:A flow delay correction means 106 corrects the relation between the fuel injection quantity determined by a fuel injection quantity calculation means 103 and the output of an air-fuel ratio sensor 100 in corresponding relation to the flow delay of an exhaust gas while a sensor detection delay correction means 107 corrects the relation between the fuel injection quantity determined by the means 103 and the output of the sensor 100 in corresponding relation to the detection delay of the sensor itself. A parameter estimation means 105 estimates the parameters of a simulation model in the fuel injection quantity calculation means 103, on the basis of that relation between the fuel injection quantity determined by this means 103 and the output of the sensor 100 which has been corrected by the correction means 106 and 107. By this, it is possible to estimate precisely the parameters of a dynamic characteristics model of fuel, thereby improving the fuel injection control performance.

Abstract: PROBLEM TO BE SOLVED: To stabilize control because the force of an operator who grips a handle does not act on a load cell by calculating a pressure of working fluid from a load signal detected by the load cell and setting a pressure of working fluid to be supplied to a drive cylinder device to control a working fluid supply means. SOLUTION: A controller 19 calculates a pressure in a drive cylinder device 8 required for holding a cargo 2 based on a load signal of the cargo 2 detected by a load cell 24 when an operation lever comes to a neutral position. Then, it outputs an electric signal to a converter device 29 so as to hold the pressure. The pressure in the drive cylinder device 8 is kept at the set and required pressure based on the results of calculation of the controller 19. A position of an operation valve part 29A of the converter device 29 is manipulated to control the flow of working fluid from an air source 41. The reaction force which cancels a weight of the cargo 2 is given to a hold arm device side by the drive cylinder device 8 so that the cargo 2 is balanced. The cargo 2 is held at the height when the operation lever is set to the neutral position.

Title: Demodulator for spread spectrum communication
Inventor: TAKAGI HITOSHI
IPC: H04B1/7085
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a demodulator for spread spectrum communication that can make a slope of an S-curve signal gentle without the need for intentionally degrading a C/N through the intentional intrusion of a noise component when the noise component is very small. SOLUTION: This spread spectrum receiver is provided with a DLL circuit 16. The DLL circuit 16 generates an S-curve signal and applies trace control to a phase of a PN code required to apply inverse processing to a spread signal on the basis of the S-curve signal. More concretely, the DLL circuit 16 continuously changes the slope of the S-curve signal in response to a correlation value equivalent to the C/N. For example, the C/N is high, the circuit 16 makes the slope of the S-curve signal gentle. Thus, the slope of the S-curve signal can almost be constant independently of the high or low C/N. Thus, the receiver can avoid disabled tracing and enhance the demodulation stability.

Title: Flow rate detector
Inventor: KURODA JIRO
IPC: G01P13/00
Filed: 1987-12-15
Abstract: PURPOSE:To ensure the detection of the stream of less flow, by moving a ferromagnetic body with the flow of the fluid, changing the path of lines of magnetic force, and utilizing the presence or absence of the action of the lines of magnetic force on a reed switch. CONSTITUTION:When fluid flows through an inlet port 1, a valve body 9 is moved upward with a hinge part 9 as a supporting point. A screening plate 10 is also moved. The screening plate 10 is deviated from the same line of a magnet member 11 and a reed switch 12. The lines of magnetic force reach the switch 12 from the magnet member 11 as shown in Figure B. The switch 12 becomes a conducting state by the magnetic force. When the fluid does not flow, the screening plate 10 is positioned on the same line of the magnet member 11 and the switch 12. The lines of the magnetic force (a) from the magnet member 11 are absorbed as shown in figure A and does not reach the switch 12. Therefore, the switch 12 keeps a free state, i.e., a non-conducting state. since the path of the lines of the magnetic force is largely changed with the flow of the fluid, the flow can be positively detected even if the flow is less.
