摘要:
A fixing device has a presser member, a slide member and a pressure belt. Both ends of the presser member are positioned outside both ends of the slide member. Both ends of the slide member are positioned outside both ends of the pressure belt. Thereby, the slide member and the pressure belt are improved in service life, so that the fixing device as a whole is improved in service life.

摘要:
A system and method for identifying a communication connection with an interim identifier prior to recognition of an original or previous identifier received via the connection. A first server or server process receives a service request (e.g., for an application, a web page or other data), and associates an original identifier with the request via one or more log entries. The request is forwarded to a second server or server process for additional or final processing. The second server associates an interim identifier with the communication connection established to receive the service request from the first server. The interim identifier is logged with one or more events associated with establishment of the connection and/or receipt and processing of the service request. When the original identifier is read and recognized, the interim identifier is bridged or mapped to the original identifier via a distinct log entry.

The invention aims at providing a pumice-based culture medium which shows outstanding characteristics as a culture medium to be used in protected horticulture. To this end, the invention provides a culture medium comprising particulate pumice having a saturated water permeability of 0.3-0.8 cm/sec and an air permeability of 15-40 cm/sec in both a dry sample and a wet sample. In another embodiment, the invention provides a culture medium having charcoal added to a culture medium comprising the particulate pumice having the above-described physical properties.

In a method and an apparatus for plating a plurality of kinds of works, an unattended route-free vehicle transports the works to a number of processing tanks to immerse the works in the processing tanks. A controller calculates a processing time of the processing tanks and a transporting time needed for the vehicle to transport the works to the processing tanks and renders the vehicle to transport one kind of the works during the immersion-processing of another kind of the works, thereby performing the plating process of a plurality of kinds of works one after another.
摘要:
A handle portion of a multipole breaker includes a handle main body, made of an insulating material, for ON/OFF operation of the multipole breaker. Movable fingers having respective movable contacts are provided for opening and closing of respective circuits, and a connecting section is interposed between the handle main body and the movable fingers for transmitting ON/OFF operation of the handle main body to the movable fingers. The connecting section has at upper positions thereof one of: (i) openings for receiving shafts formed on side walls and a center wall of a breaker case, and (ii) shafts to be fitted in recesses defined in the side walls and the center wall of the breaker case. In addition, the handle main body has, on a bottom portion thereof, a partition for insulating adjacent poles.
摘要:
A secondary ion mass spectrometer analyzes secondary ions by separating and detecting positive and negative secondary ions generated from a sample when the sample is irradiated with a high speed primary beam. The sample is irradiated with a primary beam such as a high speed atom beam and secondary ions are emitted from the sample. The emitted secondary ions are separated and detected by a quadrupole mass spectrometer. Downstream of the quadrupole mass spectrometer, a plurality of metallic rod electrodes are provided parallel to each other, some of which are supplied with a positive voltage and the rest of which are supplied with a negative voltage. An electrostatic shield surrounds the metallic rod electrodes. The secondary ions are separated into positive and negative secondary ions by the electric fields formed by the metallic rod electrodes. The separated secondary ions are respectively converted into currents by corresponding secondary electron multipliers or Faraday cups.
摘要:
An exhaust apparatus and a high vacuum pumping unit including such high vacuum device and an auxiliary vacuum pump are disclosed, wherein a high vacuum is achieved in a vacuum vessel such that the gas molecules within the vacuum vessel are ionized and accelerated to be exhausted and, further, in the high vacuum pumping unit, those gas molecules diffused back or desorbed from the vacuum pump are ionized and accelerated to be returned to the vacuum pump.
