IPC: F28F13/02
Filed: 1982-11-10
Abstract: PURPOSE:To improve boiling heat transferring properties in a heat exchanger wall by decreasing the entrance resistance to liquid which flows into the cavities under the surface of a wall, by providing a porous layer, consisting of laminated fiber, to the top of a number of slender cavities formed in the surface of a heat exchanger wall, and by interconnecting the inside of cavities with the surface of a wall by through-holes in the porous layer. CONSTITUTION:First, a number of cavities 2 in the shape of slender grooves are provided to the surface of a heat exchanger wall by a plastic work such as a mechanical cutting or a rolling. The proper size of a cavity is above 0.2mm. up to 2mm. in width, above 0.4mm. up to 2.2mm. for a pitch, and above 0.2mm. up to 1mm. in depth. Copper wire fiber of 0.18mm. in diameter and of 5mm. in length are scattered and laminated on the above-mentioned cavities, and they are sintered in vacuum at 915 deg.C by heating. By constituting the heat exchanger wall in such a manner, steam bubbles are generated in the cavities, and they are filled with the steam bubbles, when the heat exchanger wall is heated up to the higher temperature than liquid which contacts to the wall. When the pressure of steam bubbles bebecomes higher tha the liquid outside, part of the steam bubbles is discharged from the through-holes which are comparatively large among the ones in the porous layer. The other steam bubbles are left in the cavities as residual steam bubbles. At this time, a change in pressure is produced in the cavities, and liquid can easily flow into the cavities passing through a number of through-holes other than ones through which steam bubbles are discharged.

IPC: G03D3/08
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To solve the problem of corrosion resistance of energizing means used at the time of nipping a photosensitive material. SOLUTION: Roller members 62 consisting of elastic materials are integrated to the intermediate parts of shafts 60. These shafts 60 are provided with flange parts 64 on the inner side in the radial direction at both ends of the roller members 62. Small-diameter rollers 34B are provided with the flange parts 64, by which the crushing quantity (compression deformation quantity) of nip parts 62A by nip force is suppressed and the fluctuation in the inter-shaft size between the large-diameter rollers 34A and the small-diameter rollers 34B is extremely minimized. Since the fluctuation in the deformation quantity of the springs 72 is suppressed by this constitution, the fluctuation in the nip force is suppressed even if the spring constants of the springs 72 are high.  Then, the formation of the springs 72 made of synthetic resins is made possible and the problem of the corrosion resistance by processing liquids is solved.

Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To quickly and surely restore the asynchronous data to a normal synchronous state by detecting the phase difference between a clock signal and a digital receiving signal, detecting the presence or absence of a frequency error between a reference signal and the clock signal, and giving a prescribed response time constant to the output of a comparison means selected by a selection means to feed it back to a variable frequency oscillator. SOLUTION: A 1st phase comparator 2 detects the phase difference between a clock signal (fo) and a digital receiving signal Ri, and a 2nd phase frequency comparator 3 detects the phase difference between the signal (fo) and the reference signals (fs) which are continuously generated with constant frequency. A frequency detection circuit 4 detects the frequency error between both signals (fo) and (fs). A selection circuit 5 selects the output of the comparator 2 or 3 based on the output Eo of the circuit 4. The comparator 2 is selected in a normal operation mode, and the comparator 3 is selected only when the circuit 4 detects a frequency error.

Title: Air-conditioning device
Inventor: KAWADA HIROSHI
IPC: B60H1/00
Filed: 1985-09-05
Abstract: PURPOSE:To enhance the feeling of fresh cooling and the feeling of warming, by providing a blast volume distributing means for main and auxiliary blow-off ports and both suction and discharge ports, and by periodically changing the ratio of distribution of blast volumes so that pulsating air is blown off. CONSTITUTION:During cooling operation, the opening and closing of a cooling air bypass passage 10are intermittently repeated with an arbitrary period which is determined in accordance with the rotational speed of a servo=motor 9. Accordingly, cooling air passing through an evaporator 15 is branched off periodically to the bypass passage 10. With this arrangement, even if a defrost damper 19 closes a defrost blow-off port 12 due to a selected air-conditioning mode, when a damper 8 opens the bypass passage 10, cooling air is blown off from a defrost blow-off grille 12a. When the damper 8 closes, all air is blown off from a ventilation blow-off port 11. Further, these blow-off volumes are increased and decreased in association with the opening and closing operation of the damper 8 so that cooling air is pulsatively blown off. Thus, it s possible to enhance the feeling of fresh cooling and the feeling of warming.

Filed: 1989-07-27
Abstract: PURPOSE:To secure the contact width of a developer with an electrostatic latent image and the contact time by providing a magnet of polarity identical to the developer inside a cylinder that faces a photosensitive body and rotates and drives and in the vicinity of a part where the photosensitive body faces the cylinder. CONSTITUTION:The developer is maintained on the outer periphery of a thin film member 34 by the magnetic force of the magnet, and the thin film member 34 closely adheres to the outer periphery of the cylinder 31 by the magnetic attraction of the developer. The developer is not affected by magnetic force in an area facing the identical polarity part, and the thin layer member 34 does not closely adheres to the outer periphery of the cylinder 31 but forms a bulge, whose outside surface comes into contact with the outer periphery of the photosensitive body 100. Consequently, when the cylinder 31 rotates, the developer moves together with the thin layer member 34, discontinuously jumps in the identical polarity part, and is maintained at a constant layer thickness by regulating members 36 and 37. Thus, the developer is stably supplied to the part where the thin layer member 34 faces the photosensitive body 100.
