Title: Preheating controller for internal-combustion engine
Inventor: HASEDA TETSUSHI
IPC: F02P19/02
Filed: 1984-12-29
Abstract: PURPOSE:To reduce combustion noises and vibrations in an internal-combustion engine as well as to prevent an exhaust gas component from deteriorating, by checking a degree of variations in ignition timing. CONSTITUTION:Crank angle signal pulse separation Tn and ignition timing Ta are calculated from a comparison between a signal out of an ignition sensor 7 and a crank angle reference signal out of a crank angle sensor 8, and this calculated value is stored in a random access memory 12c. Next, an engine speed NE is calculated from the said separation Tn. And, the arithmetical mean is calculated from the latest data of the said ignition timing Ta. Then, a variation degree Wa in ignition timing is also calculated. Here, an allowable variation degree Ws in the ignition timing that makes the engine speed NE and the mean ignition timing a parameter, is compared with the variation degree Wa of the said ignition timing, and when Wa>Ws is the case, an energizing command is issued to a glow plug 5. Therefore, ignitability in fuel is improved and variations in the ignition timing is checkable so that even in case of what kind of engine running state, smooth combustion is attainable, thus engine noises and vibrations are reduced.

Filed: 1987-11-06
Abstract: PURPOSE:To prevent the occurrence of defective welding and to improve product quality by detecting each edge of a belt-like member by a couple of edge detectors in the vicinity of the upstream side of sizing dies and moving a movable supporting member so that the deviation of detected signals attains zero. CONSTITUTION:The edge detector 20a detects the distance from a detecting point A to one edge 4a in the axial direction of the beltlike member 4. The edge detector 20b also detects the distance from a detecting point B to the other edge 4b in the width direction of the belt-like member 4 in the same way. The outputs of the edge detectors 20a and 20b are proportioned to the distances (a) and (b) in the horizontal direction between the detecting points A and B and the edges 4a and 4b. The outputs of these edge detectors 20a and 20b are inputted to a controller 40 which produces a deviation signal from these signals. Further, the controller 40 performs PID processing on the deviation signal and produces a control signal of a servomotor 31 and controls the motor 31 and the distances (a) and (b) are equalized to each other. By this method, the occurrence of the defective welding and a pinhole is prevented and the product quality is improved.

Title: Heat-radiating structure for electronic component
Inventor: MATSUZAKI TORU
IPC: H05K7/20
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a heat-radiating structure which can accelerate the heat radiation from an integrated circuit, and at the same time, can effectively absorb electromagnetic waves, when the structure is attached to the upper surface of the integrated circuit, etc. SOLUTION: A heat-radiating structure for electronic components is constituted by successively forming a putty film 27, a electromagnetic wave absorber 29, a metallic plate 3, a dielectric 33, and a heat-radiating body 25 on an integrated circuit 24. The portions of the metallic plate 31 and heat-radiating body 25 for holding the dielectric 33 in between constitute a capacitance element. A part of the electromagnetic waves which are generated from the integrated circuit 24 and which is not absorbed by the absorber 29 is reflected by the metallic plate 31 and absorbed by the absorber 29. The remaining electromagnetic waves form an eddy current on the metallic plate 31, but the eddy current is damped, because the laminated structure at the spot forms an LC filter in cooperation with the eddy current due to the capacitance element.  Therefore, not only can the heat generated from the integrated circuit 24 be radiated, but also the electromagnetic waves can be prevented effectively from leaking out to the periphery of the heat-radiating structure.

Title: Stabilized metallic sodium dispersion
Inventor: ARIIZUMI AKIRA
IPC: B22F9/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To obtain a metallic sodium dispersion stable to water and capable of stably maintaining a dispersed state without addition of dispersion auxiliaries by dispersing metallic sodium into transformer oil. SOLUTION: A metallic sodium dispersion is produced by adding sodium to transformer oil and dispersing it by agitation. As the concentration of the dispersed metallic sodium, 1-50% is desirable and 10-40% is more desirable. Although a homogenizer is generally used for the production of a dispersion, other means, such as a method of passing through an orifice under pressurization and the use of a spiral vortex homogenizer, can be used. The average grain size of the resultant dispersion is regulated to about 1-30μ, preferably 1-10μ. Further, it is desirable that the dispersion is produced and stored in an inert gas, such as nitrogen and argon. The stabilized metallic sodium dispersion is effective, e.g. in the reaction of organic compounds and can be handled safely and easily.
