A grasping forceps for an endoscope according to the present invention comprises a flexible insertion section, an operating wire passing through said insertion section and adapted to be advanced and retreated in accordance with an operation of an operating section connected to a hand side end of the operating wire, and an elastic grasping section arranged in the leading end portion of said operating wire and composed of at least four elastic grasping members different in length having a habit of so flexing that leading end grasping portions formed at the leading ends of said elastic grasping members spread outwards from a center axis of said insertion section, wherein the leading end grasping portions formed at the leading ends of the plurality of elastic grasping members different in length are spread in a spiral arrangement at the time of spreading of the elastic grasping section. On one hand, at least the leading end grasping portion to be disposed nearest to the insertion section leading end surface and the elastic grasping member having the leading end grasping portion to be disposed remotest from the insertion section leading end surface come in an inclined relationship at the time of accommodating of the elastic grasping section.

An uneven-pattern reading apparatus includes a detecting prism having a detecting surface on which an uneven pattern is placed, an incident surface upon which an incident light beam for illuminating the uneven pattern is incident, and an emergent surface from which a light beam reflected from the uneven pattern on the detecting surface is emergent, angles between the respective detecting, incident, and emergent surfaces providing that the incident light beam is applied to the uneven pattern and the light reflected from the detecting surface is emergent from the emergent surface; an incident-light-beam converger for causing an incident light beam from a light source to be incident upon the incident surface after collimating or converging the incident light beam; an imaging device for detecting a reflected image emergent from the detecting prism; a converging optical system for collimating or converging the emergent light beam emergent from the emergent surface; and a processing device for identifying the uneven pattern on the basis of the image picked up by the imaging device, wherein an imaging surface of the imaging device is located closer to an emergent surface side than a focusing position of the converging optical system.
摘要:
Hydrogen gas from an generator (1) is occluded in a hydrogen recovery container (20), thereafter, in the initial stage during which hydrogen gas is released from the hydrogen recovery container (20), initially purged hydrogen gas containing much amount of impure gas is introduced from the hydrogen recovery container (20) to a gas tank (2) and saved therein, then, hydrogen gas having high purity released from a hydrogen absorbing alloy in the hydrogen recovery container (20) is refluxed to the generator (1), and this process comprising absorbing and releasing of hydrogen gas in the hydrogen recovery container (20) and saving in the gas tank (2) is repeated once or several times, successively, the hydrogen gas containing much amount of impure gas saved in the gas tank (2) is introduced in the hydrogen recovery container (20) and occluded therein, thereafter, in the initial stage during which hydrogen gas is released from the hydrogen recovery container (20), the hydrogen gas containing much amount of impure gas is discharged outside, then hydrogen gas having high purity released from the hydrogen absorbing alloy in the hydrogen recovery container (20) is refluxed to the generator (1).
摘要:
In a selective calling receiver receiving a first message from a transmitting side, a plurality of selective calling signals including messages and linkage orders of the messages, respectively, are sequentially received, and the messages and the linkage orders are stored into a first memory until a selective calling signal including a terminal linkage order is received. When the linkage orders stored in the first memory are numbered consecutively from a predetermined beginning linkage order to the terminal linkage order, the messages are sorted according to the linkage orders stored in the first memory to produce a second message when the linkage orders stored in the first memory are numbered consecutively. And the second message is stored as the first message received from the transmitting side into a second memory.
摘要:
A cellular radio telephone system which halts transmission and reception of a data message in the event of detection of degradation of the circuit quality regardless of whether or not a hand-over command is generated. The system employs a decoder which compares the bit error rate of a data message signal on a radio circuit between a data terminal and a base station with a predetermined threshold, and a central processor unit which generates an instruction signal instructing to halt transmission of the data message from the data terminal when the bit error rate is larger than the threshold, and thereafter generates an instruction signal instructing to restart transmission of the data message from the data terminal when the bit error rate becomes smaller than the threshold.
摘要:
A thrust bearing for use in a rolling mill, having a pair of each of working rolls and stay rolls as well as a mechanism for crossing the rolls, is provided with retainers in which pockets for retaining rolling bodies are arranged in a plurality of rows. Each rolling body, when accommodated in the pocket, has the rotating axis passing substantially the center of swing motions, which makes the bearing appropriate to the swing motions of the rolling mill. Also, centering mechanisms, collar members and stoppers are provided for the retainers, so that malfunctions can be effectively prevented.
