Abstract: PROBLEM TO BE SOLVED: To prevent toner scatter inside/outside a device body due to vibration during attachment/detachment by composing a shutter member out of a first shutter member which is positioned inside a toner supply port and a second shutter which is positioned outside the toner supply port and moves linked with the first shutter member. SOLUTION: By pushing in a toner replenishment device, the cylindrical portion of a projection 94 contacts the upward slope 114a of a guide lib, is pushed up against the biasing force of a spring member 96, and finally comes to rest on the flat top 114c of a guide rib. Accompanying the movement, the elastic member 90 of the first shutter member and the second shutter member 89 also move up along a guide and the external wall face of a toner lead-in cover 52, and the toner supply port 54 and the opening 91b of an elastic guide member 91 are opened. By pulling out the toner replenishment device, the projection 94 moves down along the slope 114a, therefore by the biasing force of the spring member 96 the first shutter member and the second shutter member 89 move in the directions in which they are automatically closed, so that they become closed.

Title: Heating device
Inventor: NAKANO OKIHIKO
IPC: F24C15/16
Filed: 1988-09-05
Abstract: PURPOSE:To prevent rollers in rotation along their circumference from slipping so as not to allow them to make rotational noises or have partial wears by providing the bottom surface of the heating chamber, the circumference of the rollers, or the like with a dimensional difference such as a slant or taper in such a way as to compensate the difference in circumferential speed of each roller between the outer rolling part and the inner rolling part relative to the axis of rotation at the center in the bottom of the heating chamber. CONSTITUTION:Each of rollers 6 is made of a ceramic or heat- and wear-resistant plastic material or the like and provided with a taper having the outer side larger than the inner side relative to the rotative center of a supporting means 7. A plane of contact 11 with the roller provided on the bottom surface 2 of the heating chamber and another 12 on the backside of a holding tray 5 are each formed in a slant on which the tapering surface fits. For the rotation of the roller 6 without slippage both at the larger- and the smaller-diameter sides, it is necessary to satisfy an equation B/A=1+2W/D wherein A represents the smaller outer diameter of the roller 6, B its larger outer diameter, W its width, and D the diameter crossing the axis of rotation to the smaller outer diameter A of the roller. For example, given D=200. A=20, W=10, and A=20, the larger outer diameter B is required to be 22 (unit mm).

Title: Radiation cooling heating heat transfer surface
Inventor: HATADA TOSHIO
IPC: F24C15/24
Filed: 1987-09-07
Abstract: PURPOSE:To provide a radiation heating surface well suitable for dissipation of heat during heating and endothermic during cooling, by a method wherein a far infrared radiation ceramic layer is formed on a base plate formed by a metal or plastic, and a hydrophilic covering layer is formed thereon. CONSTITUTION:During heating, since a base plate 1 is heated to a high temperature, an Al2O3 layer 2 and an SiO2 ultraparticulate layer 3 are also heated to a high temperature and functioned as a radiation heating surface. In this case, since the SiO2 layer is a thin film, exothermic characteristics in an infrared area where a wavelength is long is governed by characteristics of the Al2O3 layer. As a result, high spectral emissivity is provided in the vicinity of 10mum. Meanwhile, during cooling, since the base plate 1 is cooled to a low temperature, the Al2O3 layer and the SiO2 layer are also cooled to a low temperature and function as an endothermic surface. Usually, the temperature of a cooling surface is frequently kept to a value equal or lower than the dew-point temperature of ambient air, and dew condensation water is adhered on the surface of the SiO2 layer. In this case, since the SiO2 layer is an ultraparticulate layer, it has hydrophilic property, adhesion water is instantaneously wettedly and spread to form a very thin water film 4.

Abstract: PURPOSE:To couple a laser diode with an optical fiber with high efficiency by forming a surface with a hyperbolic section which converts divergent light spreading in an XZ and a YZ plane into parallel light as the refracting surface of the 1st lens and making the 2nd lens spherical. CONSTITUTION:The laser diode 11 emits the divergent luminous flux which has a large angle of divergence on the XZ plane and a small angle on the YZ plane.
