摘要:
A heat dissipating structure is provided which lowers the thermal contact resistance between a heat generating electronic component and a heat dissipating component, and markedly improves the heat radiation. The heat dissipating structure comprises a graphite sheet and a heat conducting material layer provided on at least one surface of the graphite sheet, and is positioned between the electronic component and the heat dissipating component. The heat conducting material has no fluidity at room temperature when the electronic component is not operating, but undergoes a reduction in viscosity, softens or melts, under the influence of heat generated during operation of the electronic component.

An electromagnetic wave absorbing heat conductive composition is used to form an electromagnetic wave absorbing heat dissipating article that is placed between a heat generating electronic component which, when operated, generates heat, reaches a temperature higher than room temperature and acts as an electromagnetic wave generating source, and a heat dissipating component. The composition is non-fluid at room temperature prior to operation of the electronic component, but acquires a low viscosity, softens or melts under heat generation during operation of the electronic component, to fluidize at least a surface of the composition so that the composition substantially fills any gaps between the electronic component and the heat-dissipating component.

Provided is a filter unit in which an increase in pressure loss is suppressed despite the use of an injection-molded resin as a frame. This filter unit includes a pleated filter medium 1 and a frame 2 for supporting the filter medium 1. The frame 2 has inner and outer peripheries, each of which is rectangular in shape when viewed along an air flow path through the filter medium 1. In this filter unit, the filter medium 1 is fixed to the frame 2 with a peripheral portion of the filter medium 1 being embedded inside the frame 2. The pleated filter medium 1 has a value DIP of 0.25 or less. This value DIP is obtained by dividing the distance D between adjacent ridges of the pleats of the filter medium 1 by the height P of the pleats. The distance D has a minimum value d of at least 1 mm. The frame 2 has a length La longer than a length Lm. The length La is a length of the frame 2 measured in the direction in which the ridges of the filter medium 1 are arranged, and the length Lm is a maximum length of the frame 2 measured in the direction in which the ridges of the filter medium 1 extend. The frame 2 is a resin member containing 5 to 30% by weight of glass fiber. The frame 2 can be formed by injection molding.

A mass spectrometer that allows easy replacement of an MCP (microchannel plate) and is enabled to secure orthogonality between an incident surface of the MCP and an ion track at high accuracy is provided. A flight tube 2 where ions fly is arranged in a vacuum vessel composed of a vacuum flange 6 and a body 1, and an MCP group 4 is attached to a tail end of the flight tube 2 via an MCP-IN electrode 3. A vacuum flange 6 is attachably and detachably attached to the body 1, and the MCP group 4, by a spring 710 provided on a circuit board 7 for detection attached to the vacuum flange 6, is urged toward an end portion of the flight tube 2 so that its orthogonality with respect to an ion flight track is secured.

An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.

A front fallboard, a rear fallboard and a hinge connected between them form in combination a fallboard assembly connected between side arms of a piano cabinet by means of a pair of rotary connectors, and each of the rotary connectors includes a front metal plate connected to the side surface of the front fallboard, a rear metal plate connected to the bottom surface of the side art defining a recess and a rotary damper; since the recess is wider than the rear metal plate already combined with the rotary damper, the rear metal plate is movable on a virtual plane defined by a fore-and-aft direction and an up-and-down direction; while a worker is seeking the optimum positions of the rotary connectors, self-tapping screws keep the rear metal plates in the recesses so that the worker drives woodscrews into the side arms through main holes or auxiliary holes.
摘要:
The present invention relates to a charged-particle detecting apparatus having a structure which enables adjustment of a potential distribution so as to stably maintain flight loci of charged particles without depending on a change in a voltage-applied state. The charged-particle detecting apparatus comprises a first electrode, an MCP, a second electrode, a third electrode that functions as an anode, and a rear cover arranged in order along a predetermined reference axis. The third electrode is arranged on the opposite side of the MCP with respect to the second electrode, and is electrically connected to an output signal part via a capacitor. In particular, the first electrode is arranged so as to become a part of the outer surface of the charged-particle detecting apparatus, and components positioned between the first electrode and the rear cover have contours with section sizes equal to or smaller than that of the contour of the first electrode when viewed from the first electrode side toward the rear cover.
