According to the The present invention, there are provided an electrophotographic photosensitive member, an electrophotographic apparatus comprising the electrophotosensitive member, and a facsimile system comprising the electrophotographic apparatus. The electrophotographic photosensitive member comprises a conductive support, a photosensitive layer and an intermediate layer interposed therebetween. The intermediate layer comprises a material derived from an isocyanate compound and a plurality of kinds of polyether polyol compounds, the polyether polyol compounds meeting at least one of the following requirements i) and ii):i) a ratio of a weight average molecular weight of at least one polyether polyol compound to a weight average molecular weight of at least one other polyether polyol compound is 1.3 or more; andii) at least one polyether polyol compound has different functionality from that in at least one other polyether polyol compound.

A loading lever having loading lever pins is fixed on a main chassis. Loading arms having loading arm depressed portions are rotatably attached to a slide chassis. The loading arm depressed portion engages with the loading lever pin, and the loading arm depressed portion is engaged with the loading lever pin, and in this state, the slide chassis moves in the direction of the arrow B. Therefore, loading arms move in the direction of the arrows J and K. Since the loading arms are rotated, it becomes unnecessary to slide the loading lever, and therefore, the structure of the magnetic recording reproducing apparatus can be made simple.

There is disclosed a silicon nitride based sintered material which contains 0.1% to 20% by volume of zirconium oxide, 0.1% to 14% by volume of zirconium nitride, 3% to 15% by volume of a binder phase of an Mg-Si-O-N or Mg-Si-Zr-O-N system, and balance .beta.-silicon nitride. The sintered material may include an oxide layer of an average thickness of 10 to 1,000 .mu.m in a surface thereof and having a zirconium oxide concentration increasing toward the surface thereof. A process specifically adapted to manufacture the above sintered material is also disclosed.

An aircraft lavatory unit that includes a diaper changing platform has a first side wall and a second side wall located on both sides of a toilet bowl, and a rear surface wall located to the rear of the toilet bowl. Handrails are provided on the first side wall and the second side wall. The diaper changing platform can be pivoted between a stowage position in which it is stowed in a stowage recess in the rear surface wall, and a usage position in which the diaper changing platform is lowered above the toilet bowl. The diaper changing platform is configured so that in the usage position it is supported by placing both sides of the bottom surface on the handrails of the first side wall and the second side wall.
摘要:
The present invention is intended to provide a technique which makes effective use of a phase transition temperature zone of cooling water by controlling a control valve for changing the temperature of the cooling water in an appropriate manner. The present invention resides in a cooling water temperature control apparatus for an internal combustion engine in which cooling water is caused to circulate, said cooling water having variable specific heat, said apparatus comprising: a received heat amount calculation unit configured to calculate an amount of received heat which is received by said cooling water, a control valve that is controlled to open and close according to a command so as to change a circulation route or an amount of circulation of said cooling water and to change the temperature of said cooling water, and a control unit configured to control said control valve based on the amount of received heat which is calculated by said received heat amount calculation unit.
摘要:
A lens barrel includes: a barrel body; a diaphragm pivotally held in the barrel body; a diaphragm operating member that changes the diameter of the diaphragm; an operation arm that can pivot in the barrel body and fits in the diaphragm operating member, the operation arm, when pivoted, changing the diameter of the diaphragm via the diaphragm operating member; and a light-blocking plate that prevents unwanted light from entering the barrel body and has a passage portion through which the operation arm passes and an engagement portion that an engaging piece protruding from the diaphragm operating member engages, the light-blocking plate, along with the diaphragm operating member, pivotally supported, wherein the passage portion has an opening having a width that is substantially the same as the width of the operation arm.
