摘要:
In an electric power steering device, an electric motor is drivingly connected to a steering shaft with a steering wheel for generating an assisting power to rotate the steering shaft. A memory has stored a control pattern which non-linearly varies an assisting power with variations in a steering effort. A microprocessor responsive to a vehicle speed detected by a speed sensor ascertains whether the detected vehicle speed is within a low speed range or within a high speed range. Ascertaining that the detected speed is within the low speed range, the microprocessor searches the memory for an assisting power corresponding to the steering effort detected by a torque sensor. Ascertaining that the detected vehicle speed is within the high speed range, on the other hand, the microprocessor calculates an assisting power based upon the detected steering effort and a constant. The microprocessor then outputs a control signal representing either of the searched and calculated assisting power to a signal modulator, which modulates the control signal based upon the vehicle speed from the speed sensor so that the assisting power generated by the electric motor is controlled to meet the modified signal from the signal modulator.

In an electric power steering system, a d.c. motor is drivingly connected to a steering shaft with a steering for generating an assisting power to rotate the steering shaft. Independently of an alternator for charging a battery, a d.c. generator driven by a vehicle engine is dedicated for supplying an electric power to the d.c. motor. A control circuit is responsive to a signal representing a manual torque applied to the steering and reads out one of objective values from a memory. The control circuit is further responsive to a fed-back signal indicative of a load applied to the d.c. motor and controls electric current flowing across a field coil of the d.c. generator in such a manner that the difference between the read-out objective value and the fed-back signal becomes zero.

In an automotive vehicle equipped with an electrically power-assisted steering system including an electric motor in drive connection to a steering shaft to produce an assist power in accordance with the driver's effort applied to the steering shaft, a signal is produced at each travel of the vehicle in a predetermined distance, and a physical value related to the assist power of the motor is detected in response to the signal. When the number of times of detection of the physical value reaches a predetermined time, a characteristic value of the detected physical values is calculated and compared with a standard value to determine a driving condition of the vehicle on a basis of the comparison.

A double floor structure capable of being adapted to the conditions of construction and the needs of users at low cost. A double floor structure (K) provided with support legs (1) which are provided on a lower floor and rows of beams which form an upper floor. The support legs (1) are each provided with an upper member (14) which supports a beam from the lower side, an intermediate member (13) which supports the upper member (14) from the lower side, and a lower member (12) which supports the intermediate member (13) from the lower side. The upper member (14), the intermediate member (13), and the lower member (12) consist of metallic, extruded shape material and are disposed in such a manner that the direction of the extrusion is aligned with the top-bottom direction.

There is provided a metal silicide film forming method that includes providing a substrate having thereon a silicon part (process 1); forming a metal film on a surface of the silicon part of the substrate by a CVD process using a nitrogen-containing metal compound as a film forming source material (process 2); performing an annealing process on the substrate under a hydrogen gas atmosphere; and forming a metal silicide by a reaction between the metal film and the silicon part (process 3). Here, the nitrogen-containing metal compound as the film forming source material is metal amidinate. Further, the metal film is a nickel (Ni) film. Furthermore, the metal amidinate is nickel amidinate.

A half bearing for a crankshaft of an internal combustion engine, which includes crush relieves at both circumferential end portions of an inner circumferential surface of the half bearing, is provided. The half bearing further includes an axial groove at least at a position adjacent to a crush relief on a rear side of a relative rotation direction of the crankshaft, and adjacent to the inner circumferential surface of the half bearing. The axial groove extends along an entire width of the inner circumferential surface of the half bearing.

In a banknote handling device, a banknote storage cassette is loaded along guide grooves in left and right side plates, whereby the bottom end of a bill press interlocks with protruding members of the banknote storage cassette, preventing the banknote storage cassette from exiting the guide grooves, and, by sliding a lid of the banknote storage cassette, accumulated banknotes which are stored therein are transferred to a mounting plate while a free-sliding plate member inside a storage space of the banknote storage cassette presses the accumulated banknotes downward, the accumulated banknotes being separated one by one and conveyed down a transport path by a kick-out roller, a feeding roller, and a separating roller.

A measuring instrument includes a detector that outputs a measured value, a digital display unit, an analog display unit having a plurality of display segments, and a display controller. The display controller includes: a tolerance range display unit that lights or blinks display segments corresponding to a preset tolerance range relative to a preset value; a first determiner that obtains a difference between the present value and a present measured value and determines whether the difference is within an analog display range wider than the tolerance range; a difference display unit that lights a display segment corresponding to the last one or the last two digits of the present measured value when the first determiner determines that the difference is within the analog display range; a second determiner that determines whether the difference is within the tolerance range; and an acceptance or rejection display unit that displays a result determined by the second determiner.

A digital indicator 1 includes a body case (10), a spindle (30) provided to the body case (10), the spindle (30) being movable in an axial direction, a displacement detector (40) that detects a moving amount of the spindle (30), and a digital display (50) that digitally displays the moving amount detected by the displacement detector (40). The display surface of the digital display (50) is arranged on the body case (10) in an attitude substantially orthogonal to the moving direction of the spindle (30) and deviated from the moving axis of the spindle (30).
摘要:
In a cleaning step of a substrate-processing device, vacuum drawing is made for the space between an inner chamber and an outer chamber that receives the inner chamber. Temperature of the inner chamber is set higher than the temperature of the inner chamber during substrate processing and set lower than the temperature of a substrate support member. After that, a cleaning gas containing hexafluoroacetylaceton (Hhfac) is supplied in the inner chamber, and substances to be cleaned off adhering inside the inner chamber are removed.
