摘要:
A front side of a floor panel (15) is pivotally supported on a floor panel support mechanism (21), permitting tilting of the floor panel in a forward direction with respect to a revolving frame (5) by way of a tilting mechanism (30). The tilting mechanism (30) has a guide rail assembly (33) which is pivotally supported on the side of the revolving frame (5), a screw rod (34) which is rotatably supported on the guide rail assembly (33), and a displacement member (35) which is attached to the floor panel (15) and held in threaded engagement with the screw rod (34). The floor panel (15) and a cab (29) are tilted up in the forward direction upon rotationally driving the screw rod (34) to translate the displacement member (35) constituting the tilting mechanism (30).
摘要:
A recording apparatus, which is provided with a carriage supporting a recording head or reciprocating along a platen, includes a magnetized scale of a magnetic linear encoder positioned along a moving direction of the carriage, and a magnetic head of the magnetic linear encoder, mounted on the carriage and adapted for reading the magnetized pattern of the scale. The scale is provided with at least two magnetized lines of mutually different pitches of magnetization, for recording position information relating to the recording operation, and position information relating to other functions.

摘要:
Novel hG-CSF polypeptide derivatives having an amino acid sequence derived from the amino acid sequence of the human granulocyte colony stimulating factor polypeptide by substitution of at least one amino acid by a different aminoacid and/or deletion of at least one amino acid, recombinant plasmids containing a DNA fragment insert coding for any of these hG-CSF polypeptide derivatives, microorganisms carrying one of such plasmids, and methods of producing the hG-CSF polypeptide derivatives using the microorganisms are described.
摘要:
An object inspection apparatus having a light source for irradiating an object to be inspected, a pick-up device for picking up the object and generating an image signal thereof including a synchronizing signal, and an inspecting device for receiving the image signal to determine whether or not the object has a defect. The inspecting device includes a reference position detector for generating a reference position signal based upon an image signal in a first field of the image signal and the synchronizing signal; an inspection zone position setter storing an inspection zone of a predetermined shaped and for generating a control signal based on the reference position signal and the synchronizing signal; an inspection zone controller receiving the image signal from the pick-up device and the control signal and for delivering an image signal in a second field of the image signal from the pick-up device within an inspection zone determined by the control signal; and a judging device receiving the image signal from the inspection zone controller to determine whether or not the object has a defect.
摘要:
A silver master plate recovery solution for a silver salt photographic plate for offset printing is disclosed which comprises (a) a hydrazine component for reducing the silver oxide layer of an image area, (b) a quaternary ammonium salt cationic activator and (c) water. The mixing ratio of the quaternary ammonium salt cationic activator is 3.0 to 20.0 wt % on the basis of the hydrazine component. The silver master plate recovery solution reduces the silver oxide layer of the image area of a silver salt photographic plate which has passed the stock time, thereby recovering the ink receptivity of the image area.
摘要:
A novel optically anisotropic pitch is provided which is produced by thermal modification of a polymer having a structure of an alkylbenzene and a condensed aromatic compound with two to four fused rings bonded to each other via a methylene group.In preferred embodiments, the optical anisotropy is 80% or more. As the alkylbenzene there may be used xylene, trimethylbenzene or tetramethylbenzene. As the condensed aromatic compound with two to four fused rings, there may be used naphthalene, anthracene, phenanthrene, or naphthacene. The polymer starting material may be obtained by the reaction of a xylene formalin resin, mesitylene formalin resin or alkylbenzene and a condensed aromatic compound with two to four fused rings in the presence of a protonic acid as a catalyst.
摘要:
A lighting device for apparatus detecting flaws in objects having a photoelectric sensor aligned with the object and a processor responsive to the sensor for determining the light received by the sensor. The lighting device includes a ring-shaped lamp and an opaque shield having predetermined light paths controlling the direction of the light from the lamp in a selected direction, so that the light irradiates the object to be inspected in a manner whereby the light is reflected from the object to the sensor only when the object is flawed.
摘要:
A pattern recognition method is disclosed which makes a judgment that when the difference between an object to be inspected and a previously memorized reference object falls within a predetermined value, the object belongs to the same class as the reference object. During the inspection process, the predetermined value is changed in accordance with the results of past judgment.
摘要:
A defect inspection system in which a reflector body is arranged at such an angle relative to an object to be inspected that in spite of any parallel movements of the image does not overlap the inspected object. The inspected object and the image thereof are both simultaneously picked up by the same television camera. Then, the video signal from the television camera is fed to a processor which then inspects whether or not the object to be inspected contains defects or flaws.
