A bending press system provided with a bending press (1) with at least one bending station to mount a plurality of divided tools and, tool housing devices (65, 123) to house divided metals to be used on the bending press and, tool exchange devices (61, 143) which mount said divided tools on the bending station, in which are provided a first memory means (403) which stores housed positions of each divided tool housed in the housing devices and a second memory means (405) which stores the bending line length of the bent part, the flange length and the bending angle of the bent product and, a first computation means (407) which, based on the bending line length, flange length, bending angle, computes the tool (cross section shape) type and the length of the bending station, and a second computation means (409) which, based on the tool type and length of the bending station computes the arrangement of each divided tool on the bending station, and an NC control means (411) which controls the tool exchange device so that each divided tool is moved from the housed position in the housing device to the determined arrangement position.

A method for compacting powders for powder metallurgy comprises packing powders for powder metallurgy formulated with a lubricant in a compacting die applied with a lubricant on inner wall surfaces thereof, and subjecting the powders to warm or hot compaction. The powders contain the lubricant in an amount up to 0.2 wt %, non-inclusive of 0%, based on the total of the powders and the lubricant.

An electrophotographic photosensitive member having a high sensitivity to long-wavelength light as emitted by a semiconductor laser and causing little change in potential change during repetitive use is formed by using as a charge-generating material a hydroxygallium phthalocyanine having a crystal form characterized by a strongest peak at a Bragg angle (2.theta..+-.0.2 deg.) of 28.1 deg. in a CuK.sub..alpha. characteristic X-ray diffraction pattern. The hydroxygallium phthalocyanine may preferably be produced through a process including treating a halogenated gallium phthalocyanine for conversion into a hydrous hydroxygallium phthalocyanine, freeze-drying the hydrous hydroxygallium phthalocyanine into a low-crystallinity hydroxygallium phthalocyanine, and milling the low-crystallinity hydroxygallium phthalocyanine.
摘要:
A multi-terminal surge protection device able to absorb surges of either polarity between lines and between a line and ground, in which the difference in operating time between the device elements connected to lines is reduced. A plurality of unipolar surge protection device elements are used which only operate to absorb surges of a specific polarity, and do not exhibit a reverse withstand characteristic upon application of a reverse-polarity voltage. One element is connected to a first line and another element to a second line, while a different element is connected to ground. A semiconductor substrate and second electrode are used that are common to all elements. To prevent lateral interference between elements, at least the element connected to ground is isolated from the line elements.

A sheet-postprocessing apparatus includes a sheet discharger which discharges sheets to a stacker, the stacker including a first tray adjacent to the discharger for supporting trailing portions of the sheets discharged by the discharger and a second tray for supporting leading portions of the sheets, the second tray being movable in a vertical direction and disposed downstream of the first tray with respect to a sheet discharge direction, the trays being inclined so that sheets stacked thereon slide by their own weight, such that a stack of sheets supported on both trays are stapled by a stapler, the stapled set of sheets then being pushed out of the first tray to be stacked entirely by the second tray. The sheet post-processing apparatus operates in two modes, a stapling mode and a non-stapling mode wherein sheets discharged by the discharger bypass the first tray and are supported entirely by the second downstream tray.

A sheet post-processing apparatus includes plural trays arranged along a sheet conveyance direction, wherein a sheet is stacked, bridging between the plural trays, wherein a post-processing is effected to the sheet in a part of the plural trays; a controller for controlling the trays to provide a level difference between the trays by lowering another one of the trays than the one of the trays; and aligning device for laterally aligning the sheet stacked, bridging between the trays providing the level difference.
摘要:
A mixing chamber for an air-conditioning system including a cylindrical vessel having a plurality of inlet ports provided at an axial end portion for introducing cool air from an air-conditioning unit and warm air from passenger compartments. The vessel is further provided at the other axial end portion with outlet ports. The inlet and outlet ports are oriented in a tangential direction with respect to the vessel to thereby form a spiral air flow in the vessel. The vessel has a water capturing ring located along the inner wall surface of the vessel to prevent film of water on the inner wall surface of the vessel from flowing toward the outlet ports. A water drawing slit is formed in the vessel to open to the inner wall surface at a side of the water capturing ring adjacent to the inlet ports to discharge the water accumulated at this side of the ring.
