    摘要: A counter is provided to count an output pulse which a pulse generator generates each time a vehicle moves by a predetermined distance. A microprocessor is provided to actuate a timer in synchronism with the leading edges of the output pulse from the pulse generator. The timer is set to a constant time interval during which the speed of the vehicle is to be detected. The microprocessor calculates the speed of the vehicle from the count of the counter which count is a value during the time interval from when the timer starts to operate to when the pulse generator generates a pulse just before or after the end point of the set time interval. Thus, the speed of the vehicle can be detected with good resolution and precision.

    摘要: A control apparatus for a rotation type magnetic storage device such as a magnetic disc device in which each of record tracks is composed of plural sectors, is disclosed. The apparatus comprises a memory for storing control information of address and the like of the sector to be accessed on a rotating recording medium and comparator means for comparing successively the control information read out from the sector of the rotating recording medium with the control information read out from the memory. In accordance with the output signal from the comparator, the sector of the rotating medium to be accessed is detected. The rotation type magnetic storage device having different sector formats can be controlled by altering correspondingly the control information stored in said memory.

    摘要: At least one caisson which is part or all of a breakwater forms a water chamber therein whose closure is a pendulum having a natural period in rocking or oscillating the same as a period of stationary wave surges caused in the water chamber by rocking movement of the pendulum owing to wave force impinging against the pendulum. At least one double-acting piston and cylinder assembly is connected to the pendulum, so that when a piston of the assembly is reciprocatively moved by the pendulum, pressure difference between cylinder chambers on both sides of the piston of the assembly controls a change-over valve which in turn controls hydraulic pressure discharged from the cylinder chambers to be supplied to a plurality of hydraulic motors respectively having accumulators of a type wherein accumulated pressure and volume of the hydraulic liquid are proportional to each other, whereby driving a common generator alternately by the hydraulic motors.
