A development apparatus includes an auger conveyor member for stirring and conveying developer, the gravity of the developer being eccentrically distributed with respect to a center of rotation, a drive transfer member for driving and rotating the auger conveyor member, the drive transfer member being capable of being engaged and disengaged, and a rotation detector for detecting a rotational state of the auger conveyor member. The remaining amount of the developer is detected based on the rotational state detected by the rotation detector. Alternatively, a development apparatus includes the auger conveyor member and the drive transfer member, in which the eccentric gravity distribution is achieved by a rod-like weight member eccentrically provided with respect to a rotational axis, the auger conveyor member includes a first coil spring having an inner diameter larger than an outer diameter of the weight member, and the first coil spring is inserted around the weight member in a manner which allows the first coil spring to be rotated and limits an angle of rotation of the first coil spring to a predetermined angle. Alternatively, a development apparatus includes the auger conveyor member and the drive transfer member, in which the auger conveyor member is provided near a development supply roller, and a uniforming member for making the developer uniform is provided in a space portion between the development supply roller and the auger conveyor member.

A developer container of the present invention includes a container main body and a supporting member. The container main body is used to contain a developer. The supporting member supports the container main body in such a manner that the container main body is freely rotatable. Further, the container main body includes an inwardly depressed recess portion on its outer peripheral surface. In that recess portion, a discharging opening is provided to discharge the developer into that recess portion opposite the direction in which the container main body rotates around the axis of rotation. Further, a regulating member having a tube-like shape is provided which surrounds the discharging opening to regulate the discharged amount of the developer.

An occupant protection device includes an airbag 10 that is inflated with gas from an inflator 20 at a side of an occupant B to protect the body of the occupant B from the shoulder Ba to the lumbar Bd, the airbag 10 having substantially the same vertical dimension as that of a seat back Aa. In this occupant protection device, uninflatable sections 12 and 13 are formed in a vertical center portion 10c of the airbag 10, that is, at a position corresponding to the chest Bb and the abdomen Bc of the occupant B. Accordingly, a region which is thinner than an upper portion 10a and a lower portion 10b of the airbag 10 in a vehicle width direction when the airbag 10 is inflated and that extends substantially parallel to the seat back Aa is formed substantially at the center of the airbag 10.

In an image forming system, an image forming device and a post-treatment device are provided so as to keep a distance L therebetween, by a positioning member and a transfer relaying device, and the image forming device is connected with the post-treatment device by the transfer relaying device. With this arrangement, a space surrounded by the image forming device, post-treatment device, positioning member, and transfer relaying device is made. On this account, it is possible to provide an image forming system in which an image forming device is coupled with a peripheral unit, which does not require cumbersome operations to make a space between the image forming device and the peripheral unit, on the occasion of carrying out unjamming treatment between the image forming device and the peripheral unit.

A plurality of bin units are provided with respective gates and, hence, it is possible to sufficiently narrow the clearance between the gates and the bodies of the bin unit. When the gate provided at each bin unit is expanded to lie toward a conveying path, the front edge of the gate becomes put into a dent portion of a sidewall of an image-forming apparatus. For this reason, any clearance or protrusion causing jamming of recording paper is not formed in a branch path extending from the conveying path to a discharged paper tray through the gate and, hence, it is possible to guide recording paper from the conveying path into each bin unit by means of the gate smoothly.

The names of a plurality of polyolefine resins are previously registered as index data in a name data base. An optimal operational pattern is stored in an operational pattern table for each combination of the name of a current resin under production and the name of a target resin to be produced. The optimal operation pattern is selected based on the name of the current resin under production and the name of the next target resin to be produced. Based on the selected optimal operational pattern, resin-type change control is executed.

In a transfer unit of a non-contact roller transfer method, both ends of a transfer roller shaft are supported independently of each other so as to be movable upward and downward, and an upward pushing force is provided thereto. A gap maintaining roller provided in the vicinity of each end portion of the transfer roller shaft is always in contact with the surface of a photoreceptor drum so that the gap between the surface of the photoreceptor drum and the transfer roller is maintained uniform and fixed. Further, both ends of a pre-transfer guide for guiding the sheet to the photoreceptor drum are supported in a manner such that the movement of each end accords with the movement of the end portion of the transfer roller, so that the distance between the photoreceptor drum and the pre-transfer guide is maintained uniform and fixed.

A porous fiber having sufficient chemical resistance to a variety of substances to be adsorbed, and having a large specific surface area and a large void percentage. The porous fiber provided by the present invention features a main fiber body formed of a high-density polyethylene having a melt flow rate of 0.3 to 20 g/10 minutes and numerous pores. The pores are formed by mixing the high-density polyethylene with a paraffin wax while they are melted, melt-spinning a fiber with an extruder at a draft ratio of 200 or less, stretching the fiber, heat-treating the stretched fiber, mechanically crimping it and then removing the paraffin wax. In the porous fiber, the main fiber body has a specific surface area of 20 m.sup.2 /g or more, the ratio of the pores to the main fiber body is 20% or more and the main fiber body has a size of not more than 50 denier.
摘要:
In a coaxial impact collision ion scattering spectrometer (CAICISS), a Wien filter composed of a pair of electrodes 13 and a magnet 20 is placed in the flying path of the ions. The Wien filter acts as (a) a chopper for intermittently chopping ion beam irradiated onto the sample 17, and as (b) a filter that directs only ions having predetermined mass and electrical charges toward an aperture 16 and deviates other ions or non-ionized atoms from the aperture 16. Thus non-ionized atoms or impurity ions having different mass or electric charge are prevented from irradiating the sample 17. In another CAICISS, the axis A of the ion source 11 is set oblique to the axis B of the ion beam irradiated onto the sample 14, and only ions having predetermined mass and electrical charges are deflected from the axis A to the axis B by a pair of deflecting electrodes 13.
摘要:
An ion source, a first control electrode for controlling an ion beam emitted by the ion source, a detector for detecting scattered particles, and a second control electrode for controlling the ion beam, which is directed from the ion source toward a sample, as well as the scattered particles, are arranged on the same axis along with the sample. The ion beam directed from the ion source toward the sample, and the scattered particles, which are scattered from the sample and are directed toward the detector, are caused to converge. By using an Einzel-type lens as the second control electrode, charged particles and neutral particles constituting the scattered particles are provided with a difference in speed. The detector possesses an anode plate which is divided into the form of concentric, circular plates or concentric arc-shaped plates, and each divided anode plate provides a detection output which contains information relating to a distribution of the scattering angles of the scattered ions.
