Inventor: KREMER ROBERT
IPC: F24H9/00
Filed: 1994-02-18
Abstract: In order to increase the thermal efficiency of a three-pass boiler which is used for combined heating of a domestic hot water accumulator and a building heating system, it is proposed to surround the second and third pass with a first water space (5) having a comparatively low water volume. The first water space (5) is at least partly separated from a second water space (7) by a boundary surface (8). Whereas the heating of the water in the first water space (5) via heat-exchanger surfaces takes place directly by means of the hot waste gases, the second water space (7) is heated via the boundary surface (8) indirectly and by means of gravity circulation. The first water space serves solely to heat the accumulator, whereas the second water space has the connections for the heating-system circuit. The connection piece (9) for the flow of the accumulator circuit is situated at the highest point of the boiler and the return connection (10) at the lowest point of the first water space (5). At the same time, the water spaces (5, 7) are interconnected in this region, so that a normal gravity-flow operation of the boiler is possible. On the other hand, when a feed pump for the accumulator circuit is switched on, the gravity flow is cut off. <IMAGE>

Abstract: A cooling apparatus for integrated circuit chips (112) in which the pressure of coolant does not affect the chips (112) is disclosed. A block (121) is provided with a plurality of holes. Cooling members (131) are inserted in these holes. An elastic member (134) is filled between the block (121) and the cooling member (131). The cooling member (131) is supported to the block (121) by the elastic member (134). Each cooling member (131) is connected to each other by pipes (132). A bellows (133) can be provided between the cooling member (131) and the pipe (132). When the block (121) is loaded on the substrate (111) on which the integrated circuit chips (112) are mounted, the elastic member (134) deforms and the cooling member (131) displaces in accordance with the height and inclination of the integrated circuit chip (112). The lower surface of the cooling member (131) is brought into close contact with the integrated circuit chip (112) due to the deformation of the elastic member (134). The bellows (133) deforms in accordance with the displacement of the cooling member (131) to ensure the normal connection of the pipe (132). When the coolant is supplied, the expanded bellows (133) pushes the pipe (132) up but does not push the cooling member (131) down.

Abstract: A series section metallized film capacitor in which the metal layers are varied in thickness such that high oxidation areas are thicker than low oxidation areas. In particular, the edge portions bordering a center margin electrode gap have a thickness which is greater than the remaining area of the center margin electrode. The increased thickness at the edge portions reduces the oxidation effect and the associated decrease in capacitance which normally occurs due to the electric potential across the gap. By varying the thickness, the oxidation effect at the edge portions is reduced while the self-healing capabilities at the low oxidation areas is maintained.

Abstract: A very deep P⁺ diffusion step is performed prior to the definition of a self-aligning emitter/P⁺ region. Furthermore, the initial P⁺ region is formed with dimensions sufficiently narrow to allow the subsequent emitter/P⁺ formation step to overlap the deeper P⁺ step by enough distance for the P⁺ step to completely cover the deep P⁺ region with its significant lateral diffusion. In this manner, a low sheet resistance in combination with proper alignment of the P⁺ heavy region with the emitter region is obtained.

Abstract: A method for controlling resistance welding adaptively optimizes a set value of welding current for the next welding operation by inference from monitored signals of the present welding operation. In an embodiment, a welding current I and a change of resistance ΔR across welding electrodes are measured during a welding operation. The number of welding operations N involving the welding electrodes is incremented. After the present welding operation, these values of ΔR, I and N are mapped into compatibility degrees of respective antecedent membership functions. Compatibility degree of conclusion membership function of each control rule is computed from its antecedent membership function compatibility degrees. Then compatibility degree of conclusion membership functions U, S and D is composed. From the composed compatibility degree, an operation value i.e., percent change of set welding current is computed by the center of gravity defuzzification method. Finally, using the percent change, the set value of welding current is corrected. The corrected set welding current is used for the next welding operation.

Inventor: IKUTA KUNIO
IPC: G06T9/00
Filed: 1997-01-24
Abstract: Error data Σe P  accumulated for a target pixel of binary coding or pixel of interest P is read from an error memory (20) and inputted into an adder (22). The adder (22) adds the error data to multi-valued image data regarding the pixel of interest P, so as to correct the multi-valued image data. A comparator (24) compares the corrected multi-valued image data outputted from the adder (22) with a predetermined reference value and outputs binary image data based on a result of the comparison. A bit converter (28) converts the one-bit binary image data to 8-bit data. A subtracter (26) subtracts the binary-coded image data from the image data prior to binary coding to obtain an error 'e'. An error distribution circuit (30) distributes the error 'e' into pixels A, C, D, and E, where the pixels A, C, and D are respectively located on the immediate right of, immediately below, and on the lower left of the pixel of interest P and the pixel E is located on the immediate left of the pixel D. The error memory (20) adds distributed portions of the error e A , e C , e D , and e E  to error data Σe A  , Σe C , Σe D , and Σe E , so as to update the values of the error data Σe A  , Σe C , Σe D , and Σe E . This method of distributing the error 'e' into the above peripheral pixels enables multi-valued image data for the pixel of interest P having a relatively low tone value or a relatively high tone value to be binary coded without damaging the quality of picture.
