Title: Predicting method of water level and flow rate in open channel
Inventor: SHIOTANI MAKOTO
IPC: G06F19/00
Filed: 1983-07-27
Abstract: PURPOSE:To decrease the amount of calculation and make the calculation uniform and high in precision by adapting a difference speed momentarily in the middle of the calculation, and reducing both a space difference interval and a time difference interval until errors are within specific ranges. CONSTITUTION:A setting part for an initial state quantity condition and an initial environmental condition sets the initial conditions in a time and a space area. Further, a setting part 2 for the initial trial value of the space difference interval sets the initial trail value of the space difference interval. Then, a point P on a characteristic curve passing through an origin and a point on another characteristic curve passing through the point P are found. Then, the quantity of state and phenomenon propagation speed as to the given point P' are calculated and the time difference interval is adapted to the propagation speed, thereby deciding that the quantity of state and phenomenon propagation speed converge. Next, a new calculation point which is not covered with a characteristic curve from a contiguous calculation point and present on a time line on which a reference calculation origin R' is prevent is generated to calculate all calculation areas, and a decision 5 is made after the calculation is completed, so that a calculation end signal is outputted 6.

Title: Frequency measuring instrument
Inventor: HATANO TSUYOSHI
IPC: G01R23/10
Filed: 1988-06-02
Abstract: PURPOSE:To prevent a decline in the measuring accuracy of the title instrument caused by asynchronism between burst waves and input pulses by correcting the sampling time and counted number of pulses in accordance with the phase relation between the input pulse of the burst waves and sampling period. CONSTITUTION:When input pulse S1 are given to a one-shot circuit 1, one-shot outputs are produced in corresponding to the pulses. Then pulses S3 having a burst period are produced by taking the AND of the outputs and pulses S1. Moreover, the pulses S1 and S3 and sampling clocks SC are synchronized to fractional time counting clocks EC by means of a synchronization circuit 3 and respectively become synchronizing input pulses S4, synchronizing burst pulses, and synchronizing sampling clocks. The signals become fractional hour counter clearing signals S7 and latch signals S5 after ANDs of the signals and the clocks EC are taken and a fractional clock counter 6 counts the number of fractional clocks by using the signals. The pulses S4 are inputted to an input pulse counter 4 and the confliction between input pulse counter clearing signals S6 and the signals S5 is prevented by shifting the signals S5 by the half period of the clocks EC.

Title: Anti-lock brake control device
Inventor: TAKEDA KENJI
IPC: B60T8/36
Filed: 1995-06-02
Abstract: PURPOSE: To provide an ABS control device reducing pulsating pressure generated in hydraulic piping and a wheel cylinder. CONSTITUTION: During ABS operation, a pressure boosting valve 3 cuts off communication between a master cylinder 1 and a wheel cylinder 5, and the pressure of the wheel cylinder 5 is boosted after reducing the pressure of the wheel cylinder 5 by a pressure reducing valve 6, so that the pressure reducing valve 6 cuts off communication between the wheel cylinder 5 and a reservoir 7. When the pressure boosting valve 3 repeats conduction and cut-off between the master cylinder 1 and the wheel cylinder 5 to boost the pressure of the wheel cylinder 5, a differential pressure control valve 2 controls the pressure Pc of a control pressure chamber 22 to be always higher by a certain fixed value, less than 20 bar, for instance, than the pressure Pw of a wheel cylinder pressure chamber 21.  Pulsating pressure in piping and the like can thereby be suppressed so as not to cause the generation of noise.

Filed: 1986-06-12
Abstract: PURPOSE:To contrive a shorter acceleration time, by providing spring means for energizing a carrier at the time of reversion of the moving direction of the carrier, at both ends in the moving directions of the carrier. CONSTITUTION:At both ends in the moving directions of a carrier 4, spring means 14 such as coil springs for energizing the carrier 4 at the time of reversion of the moving direction of the carrier 4 are oppositely provided on side frames 1. The carrier 4 is moved beyond a printing range W into an acceleration distance S', when an end face of the carrier 4 presses the spring 14, thereby accumulating energy in the spring 14. Therefore, when the moving direction of the carrier 4 is reversed, the carrier 4 is accelerated rapidly and in a short time (short distance) by both a motor and energization by the energy accumulated in the spring 14. Namely, let F by a driving force of the motor and k be the spring constant, then the carrier 4 can be accelerated in a distance shorter by k<3>/2 than that when the spring is not used. Accordingly, the acceleration time and acceleration distance for the carrier can be shortened, and a smaller device can be contrived.
