摘要:
An electric actuator including a stationary housing, an output shaft rotatably supported by the housing, an output member mounted on said output shaft, an electric motor secured to the housing, speed reduction gear mechanism for reducing the rotational speed of the electric motor, differential gear mechanism provided between the output shaft and the speed reduction gear mechanism, an electromagnetic brake operatively connected to the differential gear mechanism. The differential gear mechanism includes an output side differential gear secured to the output shaft, and a brake side differential gear rotatable with a brake plate of the electromagnetic clutch. The electromagnetic brake includes an electromagnetic coil and an electromagnetic yoke secured to the housing, so that when the brake side differential gear is prevented from rotating by the electromagnetic brake the electric motor controls displacement of the output member, and when the brake side differential gear is freely rotatable relative to the housing the output member is freely rotatable irrespective of the rotation of the electric motor.

The timing of spark ignition is set in normal operating conditions at a programed spark advance angle corresponding to the MBT (minimum spark advance for best torque). When knocking of the engine is detected by a vibration sensor, the ignition timing is delayed by a predetermined amount, e.g., 2.DELTA..theta., for each engine cycle that knocking is detected in synchronism with the rotation of the engine. When knocking is not detected, the ignition timing is advanced by another predetermined amount, for each engine cycle that knocking is not detected. e.g., .DELTA..theta.. In this method for controlling the spark timing, the amount of retardation, 2.DELTA..theta., is selected to be larger than the other amount of advance, .DELTA..theta..

In a carburetor for an internal combustion engine, a control valve is disposed with an air passage through the carburetor structure to control the flow quantity of air to be mixed with fuel from a float chamber and a pneumatic servo-motor is operatively connected with the control valve to control the opening degree of the valve. The pneumatic pressure applied to the servo-motor is electrically controlled to satisfy the following function in relation to the engine intake manifold vacuum and the engine speed.Pd=f(Pv, N)where the character Pd is the pneumatic pressure applied to the servo-motor, and the characters Pv and N respectively indicate the engine intake manifold vacuum and the engine speed.

A following distance measuring communication system comprising a transmitter and a receiver which are mounted on the front part of a following automotive vehicle, a time measuring unit connected to the transmitter and the receiver provided on the following automobile, and an answering transmitter-receiver unit mounted on the rear part of a preceeding vehicle. A pulse modulated signal is transmitted from the transmitter on the following vehicle, and this signal is received by the answering transmitter-receiver unit on the preceeding vehicle. At the instant that the signal is received, the answering transmitter-receiver unit on the preceeding vehicle generates a reply signal which is in turn received by the receiver on the following vehicle. The time required for this process is measured by the time measuring unit connected to the following vehicle receiver to determine the distance between the following vehicle and the preceeding vehicle.
摘要:
There is provided a relative distance indicating speedometer for a vehicle comprising relative distance detecting means for measuring the relative distance of a vehicle carrying the speedometer with respect to an object such as the vehicle in front, and relative distance indicating means for indicating the measured relative distance in accordance with the output signal of the relative distance detecting means. The relative distance indicating means are arranged in the speedometer which indicates the speed of the vehicle, and therefore the apparatus of this invention is inexpensive to manufacture and simple in construction.
摘要:
A powder transfer mechanism laminates powder layers containing water-soluble powder as a main component one by one at a modeling portion. An inkjet line head injects a water-based ink that dissolves the powder in an area of an uppermost layer of the powder layers laminated by the powder transfer mechanism, the area corresponding to a cross-sectional shape of a modeled object. Then, a heater heats the powder for each layer of the powder layers. Further, the heater heats the powder after the water-based ink is injected by the inkjet line head or before the water-based ink is injected by the inkjet line head. The present invention can be applied to a modeling apparatus, for example.

Disclosed is a method of manufacturing a molded object. The method includes: supplying a first liquid material to a first region out of a molding enabling region where a powder material is arranged and curing the powder material of the first region using a lamination molding technology to form a first insoluble part insoluble in a solvent; supplying a second liquid material different from the first liquid material to the powder material of a second region, which is provided so as to be surrounded by the first region, out of the molding enabling region and curing the powder material of the second region using the lamination molding technology to form a second soluble part soluble in the solvent; and dissolving the second part in the solvent.

摘要:
A print head which includes at least two discharge nozzle lines arranged on at least two lines, out of a base line corresponding to a radial direction of the rotating print object and at least one offset lines parallel to the base line, discharges ink drops of the same color from discharge nozzles of the discharge nozzle lines, moves the print head so as to minutely move the discharge nozzle lines on the base line or the offset lines, and discharges ink drops of the same color from the discharge nozzles passing through second paths moved minutely from the first paths over the rotating print object. In this way, the ink drops are discharged on the area where print defects are caused because the area is not on the paths of the discharge nozzles before the discharge nozzles are minutely moved.
