摘要:
When the number of pieces of data which are operated on by an operation unit per unit time is N times the number of pieces of data entered into a data entry section per unit time and the operation unit performs an operation on a data set consisting of K samples of data, the data set extraction starting positions on a data string entered into the data entry section are shifted by K/N samples. Each of data sets thus extracted from the data string is sent to the operation unit to be operated on. This configuration permits the precision of operations by the operation unit to be improved according to the ratio K/N without reducing the operation efficiency of the operation unit.

Herein disclosed is an information processing apparatus having a synchronous storage and the synchronous storage which can resume an operation continuing from before an interruption without hindrance even after a series of read/write operations have been interrupted and a read/write of internal condition values has been performed in a scanning operation or the like. The information processing apparatus successively selects information stored in address backup registers in two stages and data backup registers in two stages and outputs the selected information to the synchronous storage when a normal operation is resumed, thereby restoring an address data register, a data input register and a data output register to the same conditions as before the interruption of the normal operation. This invention is applicable to a synchronous storage accessible in synchronism with a system clock and an information processing apparatus having such synchronous storage.

A hydraulic control device for a continuously variable vehicle transmission having a closed hydraulic circuit disposed between a hydraulic pump and a hydraulic motor, with at least one of said hydraulic pump and said hydraulic motor being of the variable displacement type. The hydraulic pump is driven by an engine and the hydraulic motor is connected to the road wheels and is driven by hydraulic pressure from the hydraulic pump. A pair or relief valves are disposed between the two oil passages of the closed hydraulic circuit extending between the hydraulic pump and the hydraulic motor, each of which are for relieving the pressure from one oil passage to the other oil passage. One relief valve relieves the pressure from the oil passage which has the higher pressure when the continuously variable transmission is driven by driving forces from the engine to drive the road wheels, and has a relief pressure setting controlled so as to increase as the speed of rotation of the engine increases. The other relief valve which relieves the pressure from the other oil passage which increases in pressure when said continuously variable transmission receives driving forces from the road wheels, has a relief pressure setting controlled so as to increase as the speed of the motor vehicle increases.

A hydraulic continuously variable transmission for use on a vehicle comprises a hydraulic variable pump, which is driven by an engine, and a hydraulic variable motor, which is driven by oil discharged from the hydraulic variable pump to drive wheels. In addition, this transmission includes shift position detecting means, which detects a shift position, and vehicle stop detecting means, which detects whether the vehicle is in halt. In this transmission, when the vehicle stop detecting means detects that the vehicle is in halt and the shift position detecting means detects that the shift position is in a forward or rearward drive position, the discharge capacity of the hydraulic variable motor is set to a maximum, and the discharge capacity of the hydraulic variable pump is controlled to a predetermined capacity (first predetermined capacity) in correspondence with the shift position. Thereby, the vehicle is prevented from relapse phenomenon, i.e., being dragged in the direction opposite to the direction set with the shift lever when the vehicle is stopped on a slope.

A hydraulically operated continuously variable transmission associated with the engine of a motor vehicle has a clutch for controlling the transfer of power through the transmission and a hydraulic servo unit for selectively connecting and disconnecting the clutch. A clutch control device comprises a first discharge oil passage for discharging working oil from the hydraulic servo unit when the clutch is connected by the hydraulic servo unit to start the transfer of power, an orifice disposed in the first discharge oil passage and having a prescribed cross-sectional area, a second discharge oil passage for discharging the working oil from the first discharge oil passage, the second discharge oil passage communicating with the first discharge oil passage upstream of the orifice with respect to the direction in which the working oil flows through the first discharge oil passage, and a relief valve disposed in the second discharge oil passage and openable only when the pressure of the working oil in the second discharge passage is higher than the pressure of the working oil which is developed in the first discharge oil passage upstream of the orifice when the working oil is at a normal temperature. The degree to which the flow of the working oil is restricted by the orifice may be modified by an orifice charging valve depending on the magnitude of an indication of the throttle valve opening of the engine.

A plasma analyzer for trace element analysis has a gas supply system comprising a plurality of gas sources, an electromagnetic valve provided on a line connecting each gas source to a plasma generating space, a buffer tank provided after the electromagnetic valve on the line, and a flow regulating flowmeter provided after the buffer tank on the line. Each electromagnetic valves is controlled for on-off operation and the corresponding buffer tank suppresses the sudden change of the flow rate of the corresponding gas, so that the composition of the gas supplied to the plasma generating space changes gradually in spite of the simple on-off operation of the electromagnetic valves. Thus, the fluctuation and extinction of the plasma attributable to the sudden change of the composition of the gas supplied to the plasma generating space can be effectively prevented.

A hydraulically operated automotive transmission on an automobile includes a hydraulic pump coupled to an engine-operated input shaft, a hydraulic motor coupled to a wheel-driving output shaft, a closed hydraulic circuit connected between the hydraulic pump and the hydraulic motor, and a bypass passage connected between the inlet and outlet ports of the hydraulic pump in bypassing relation to the hydraulic motor. A clutch control system combined with the transmission comprises a clutch valve disposed in the bypass passage for selectively opening and closing the bypass passage, and an automatic control device coupled to the clutch valve for controlling the operation of the clutch valve. The automatic control device opens the clutch valve to a first extent which prevents the automobile from creeping while the engine is idling, and closes the clutch valve to a second extent which prevents the engine from racing when the automobile is started.
