Patent JP-S59157487-A (JP)
Title: Heat exchanger
Inventor: YAMADA YUKIO
IPC: F28F13/16
Filed: 1983-02-25
Abstract: PURPOSE:To improve the heat exchange efficiency by a method wherein fins and a heat transfer pipe are made to have different potentials and dust included in a dielectric heat collecting medium is forced to adhere to the fins so that the dust is prevented from adhering to the inner surface of the heat transfer pipe and the conduction of radiant heat is also performed. CONSTITUTION:The cross-shaped fins 2 are provided within the heat transfer pipe 1 through which the heat collecting medium such as an exhaust gas flows. In order for an electric field to be formed between the heat transfer pipe 1 and the fins 2, the fins 2 and the heat transfer pipe 1 are electrically connected to each other with the fins 2 being made to act as an anode and the heat pransfer pipe 1 as a cathode. Further, projecting electrodes 3 same in number as the fins 2 are provided on the inner surface of the heat transfer pipe, preferably at the intermediate parts of the fins 2. The polarity of the projecting electrode is negative like the heat transfer pipe 1. With the above structure, the radiant heat is transmitted to the heat transfer pipe 1 as shown by the letter Q so that the heat collecting efficiency of the heat transfer pipe 1 is further promoted. In addition, foreign substances in the exhaust gas tending to adhere to the inner surface of the heat transfer pipe 1 are all forced to adhere to the fins 2 due to the electric field.

Title: Deflection yoke
Inventor: OKUZONO EIJI
IPC: H01J29/76
Filed: 1994-03-01
Abstract: PURPOSE:To improve deflection sensitivity to attain a downsizing by providing a ring magnetic body on the end surface of a bent up part to take the magnetic field generated near the bent up part into the inner part. CONSTITUTION:A neck part-side bent up part A and an opening part-side bent up part B have, on the bobbin frame end surfaces, ring magnetic pieces 1a, 1b corresponding to the respective diameters. The ring magnetic piece 1b is fixed by a large cover 4, and the ring magnetic piece 1a may be similarly fixed by a cover. In such a constitution, when a current I is carried to a horizontal deflection coil 5, the magnetic field by the magnetic lines of force generated in the bent up parts A, B are prevented from being swollen outward by the ring magnetic pieces 1a, 1b, and curved small to the inner part of the deflection yoke. Since the magnetic filed in the deflection yoke is thus enhanced, the deflection sensitivity is improved to realize the downsizing. The ring magnetic piece may be provided on only either one of the neck part and the opening part.

Holes 6 are then provided in the portions 22, 32. The portions 11, 32 are melt-bonded to each other at the holes 6 so that the internal spaces of the portions communicate with each other. A hole 6 is provided in the portion 11 near the end 31a. The portions 11, 32 are melt-bonded to each other so that their internal spaces communicate with each other. This results in providing a bent tube shaped as double U's and having a reduced gap between its portions. A fluorescent lamp is thus made compact.

Title: Directory arithmetic system
Inventor: AOKI HISAYUKI
IPC: G06F7/22
Filed: 1987-02-12
Abstract: PURPOSE:To simplify the designation for a file gathering of complicated conditions by picking up each component element as a cell out of a directory arithmetic formula converted into a reverse polish notation and performing the directory arithmetic in response to each cell to save this arithmetic result into a stack. CONSTITUTION:A conversion means 1 converts a designated directory arithmetic formula into a reverse Polish notation. An input means 2 picks up each component element out of said converted directory formula as a cell. A deciding means 3 decides the contents of the input cells and branches the processing based on the deciding result of said decision. A directory arithmetic means 4 performs the directory arithmetic in response to each cell and a stack saving means 5 saves the directory arithmetic result into a stack. Then a result return means 6 takes the result of the final directory arithmetic formula obtained through repetition of operations of said means as necessary out of the stack and copies of the obtained arithmetic result into a designated area. In such a way, a file gathering of complicated conditions is designated.

Abstract: PURPOSE: To provide a cheap temp. indicating compsn, which showns a reversible color change at a specific temp. and is simply prepared by adding a micelle-affinitive coloring matter to a suspension contg. and ionic surfactant at above the critical micelle concn.  
     CONSTITUTION: The ionic surfactant is suitably selected from anionic, cationic and amphoteric surfactants having the Krafft point corresponding to a temp. to be measured, and it is generally used in a concn. range from twice as high as the critical micelle concn. to 30% of the concn. The micelle-affinitive coloring matter includes an oil-sol. coloring matter which fuses with lipophilic group parts of  micelle or and ion-affinitive coloring matter which is electrically adsorbed on the micelle surface. The coloring matter is added at concn. needed to color the suspension, e.g. 10 -5  mol/l. The surfactant changes from a cloudy state to a transparent state on the borderline of the Krafft point, forming surfactant micelle, and the coloring matter binds to the micelle, showing a clear color change, so using this compsn. a predetermined temp. can be observed easily with the naked eye.
