Provided is a method for making a double-walled yoke that allows an inner yoke (4) and outer yoke (3) to be integrally joined to each other both easily and securely. Such a yoke provides an adequate cross sectional area for a magnetic path of the yoke while minimizing the weight of the yoke. A tubular member (14) destined to be form the inner yoke and a cup-shaped member (13) destined to form the outer yoke are both fitted on a punch (7) and a drawing process is executed by using an appropriate drawing die (8). The outer yoke may have a small wall thickness as long as it is capable of retaining its shape during use or supporting a bearing for the motor. The inner yoke is required to be relatively small in size as long it is capable of forming a satisfactory magnetic path for the motor. A satisfactory magnetic path can be obtained if the yoke is provided with an adequate wall thickness so as to provide an adequate cross sectional area for the magnetic path.

There is a workpiece clamp device 10 for horizontally holding a thin section long workpiece 1 having a constant section shape or having the same section shape in spaced positions in a longitudinal direction in two positions of the same section shape. The workpiece clamp device 10 is constituted of a driving clamp device 10A and a driven clamp device 10B comprising the same holding device 12. The driving clamp device 10A rotates the workpiece 1 centering on a horizontal axis O extending in a longitudinal direction of the workpiece, and the driven clamp device 10B follows movement of the workpiece and idles centering on the horizontal axis. An arbitrary portion to be machined of the workpiece can be directed in a direction in which the portion is easily machined by the rotation (e.g., upward direction).

A fuel injection valve is capable of minimizing the waste of fuel and variations in the air-fuel ratio by weakening a water hammer action occurring as a result of sudden closing of a needle valve and thus suppressing the occurrence of a bouncing phenomenon. A water hammer absorbing member is provided between an armature and an injection hole to absorb and damp a water hammer pressure wave produced by sudden closing of the needle valve. Therefore, it is possible to reduce the pressure wave propagated to the armature, to which the needle valve is integrally secured, and hence possible to reduce the amount of lift of the needle valve due to a bouncing phenomenon. Accordingly, the amount of fuel excessively discharged is reduced. Thus, it becomes possible to minimize the waste of fuel and variations in the air-fuel ratio.

A bleached pulp having a high brightness and a satisfactory pulp viscosity is produced from a lignocellulosic material with a high efficiency by subjecting an aqueous slurry of a pulp to a bleaching step including at least one stage in which the pulp is bleached with chlorine dioxide under a pressure of, for example, 0.0980 to 0.883 MPa (1.0 to 9.0 kg/cm2), created by a compressed gas, preferably at a pH of 2 to 5, at a temperature of 50 to 120° C. and in a pulp consistency of 5 to 40%.

摘要:
To achieve an intermediate lock state in a short period when an engine is stopped and improve the accuracy of confirmation of the intermediate lock state, an engine valve timing control apparatus includes a variable valve timing mechanism configured to vary engine valve timing, and an intermediate lock mechanism configured to restrict relative rotation positions of a first and a second rotor of the valve timing mechanism at an intermediate lock position for starting the engine. Upon detection of an engine stop request, the valve timing mechanism and the intermediate lock mechanism are driven and controlled for establishing an intermediate lock state. When a predetermined period from detection of the engine stop request has expired without detecting the intermediate lock state within the predetermined period, an engine stopping process is executed. Even after the engine stopping process has been executed, monitoring of the intermediate lock state is continued.

A projector 22 projects video onto a surface of an infrared light reflection member 26 following control by a PC 20. A detection unit 24 includes an infrared light emitter 28 and a depth camera 30. Since the infrared light which is reflected by the infrared light reflection member 26 does not return to the depth camera 30, the infrared light reflection member 26 is an area whose distance is unmeasurable. Further, a distance can be obtained outside the infrared light reflection member 26 since the infrared light is diffusely reflected. This allows obtainment of the relative relationship between the position of an outer periphery of the infrared light reflection member 26 and the position of an object 32. Accordingly, a touched position can be calculated, and a process on the basis of that is possible.

A deformable mirror device compensates the spherical aberration caused by the difference of thickness of the cover layers covering recording layers of an optical disc. Circular projections are concentrically arranged on a flexible member (2) where a mirror surface (3) is formed to produce a strength distribution pattern (2a). Attractive force is generated as electrostatic force between an upper electrode (8) and a lower electrode (9) according to the voltage applied from a drive circuit (10) so as to contract the second space (7) and accordingly expand the first space (5) in order to deform the mirror surface. At this time, the profile of the mirror surface is deformed to show a desired profile that can compensate the spherical aberration by the pattern formed on the flexible member (2) as strength distribution pattern (2a). With this arrangement, only a single drive actuator (10) is needed to deform the mirror surface to simplify the configuration and the control operation. The mirror surface can be deformed stepwise to show predetermined deformed profiles depending on the pattern formed as strength distribution pattern (2a). Then, it is possible to compensate the spherical aberration for each of the three or more than three recording layers of the optical disc.
摘要:
An optical element and manufacturing method of the present invention prevent the incidence of light on unnecessary portions of the optical element so that stray light and noise are eliminated. The optical element is configured from at least one substrate having a plurality of lens substrates that have embedded lenses made of a material with a higher refractive index than the at least one substrate. A shielding means limits the optical path so that incident light propagates only within a prescribed optical path formed on a light incidence-side or emission-side surface of one of the lens substrates. In addition, the shielding means is formed from an absorptive or reflective film placed in a region outside the prescribed optical path or through machining the region outside the prescribed optical path.

A questionnaire producing and aiding system according to the present invention is arranged to store a questionnaire element including a question and a plurality of reply choices which have been previously produced in a memory thereof. When a questionnaire is produced, the saved questionnaire element is used while adding, correcting and deleting the contents so that a questionnaire sheet is produced. Therefore, the questionnaire producing operation can be performed efficiently. The data about the produced questionnaire sheet are stored in a portable recording medium.The questionnaire reply gathering system according to the present invention is arranged to read data about the questionnaire sheet from the storage medium to display the contents of the questionnaire sheet on the terminal display apparatus, and to gather reply data supplied from the terminal input apparatus to be stored in the portable storage medium. The questionnaire reply gathering system is constituted by a small portable computer so that a questionnaire can be conducted after it has been moved to an arbitrary place.The questionnaire totalizing and analyzing system according to the present invention performs a totalizing process and an analyzing process by reading instructed reply data from the storage medium.As described above, data are transmitted/received between systems by means of the portable recording medium so that a necessity of establishing a direct connection between systems by using communication lines or external input apparatus can be eliminated, and thereby the handling facility can be improved.
