Title: Soldering method for electronic component
Inventor: ISHIKAWA TAKATOSHI
IPC: H05K3/36
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a soldering method for an electronic component, in which the electronic component can be soldered with good efficiency by a reflow operation without cleaning the flux. SOLUTION: In a soldering method for an electronic component 1, the electronic component 1 is bonded to a board 8 by a soldering operation. In the soldering method, solder bumps 2 on the electronic component 1 are coated with a temporary fixing agent 6, containing a high-viscosity volatile organic material which has activating action and whose boiling point is higher than the highest heating temperature in the soldering process. After that, the solder bumps 2 are aligned with electrodes 9 to be fixed temporarily by the temporary fixing agent 6, this assembly is heated in a reflow furnace, and the solder bumps 2 are melted to be soldered to the electrodes 9. Since oxide films on the solder bumps 2 are removed by an active component in the temporary fixing agent 6, the electronic component 1 is soldered satisfactorily without the use of flux. Since after the electronic component 1 has been soldered, the temporary fixing agent 6 evaporates and does not remain, cleaning operation is not required after the soldering.

Title: Compiling list processing system
Inventor: HAYAKAWA AKIRA
IPC: G06F9/06
Filed: 1989-02-16
Abstract: PURPOSE:To emphasize and output a prescribed word so as to easily read a source program by converting a designated word into a prescribed emphasis output form. CONSTITUTION:A compiler 21 translates a source program 8 of a computer and produces a compiling list file 10. A source program reading part 22 is added to the compiler 21. The part 22 contains a means which receives the prescribed designation input that designates a specific word as an emphasizing word. When the designation input is received, it is processed by a compiling list conversion part 23. In other words, the designated word is converted into a prescribed emphasis output form for production of a compiling list file 24 in terms of a part corresponding to the contents of the source program of the file 10. Thus it is possible to easily output a desired word after emphasizing the word with designation so that it is easily discriminated from other words.

Title: Preparation of coating material of fried food
Inventor: NAKATSUBO TADASHI
IPC: A23L5/10
Filed: 1983-03-09
Abstract: PURPOSE:To obtain a coating material of fried food causing no water release after thawing, having no reduction in quality even after long-period preservation, by applying a batter solution to a core food, coating the food with bread crumb, heating it by microwave. CONSTITUTION:In preparing a fried food, a batter solution is applied to a core food, which is coated with bread crumb, and heated by microwave. It may be considered that starch is previously gelatinized, bonding of starch to water is strengthened, and formation of film on the surface can prevent water release, but, when the starch in the batter solution is heated, and impasted, viscosity of the starch is raised, uniform adhesion of the starch to the surface of the core food is impossible, so concentration of the starch must be <=10wt% at the utmost. The low concentration like this still causes water release after thawing. On the contrary, when a batter solution is prepared from raw starch, a core food is covered with it, coated with bread crumb, and heated by microwave, water release is prevented, the above-mentioned demerit is solved.

Title: Base plate for lead-storage-battery electrode plate
Inventor: NAGATA YUKIHIRO
IPC: H01M4/73
Filed: 1982-03-11
Abstract: PURPOSE:To increase the characteristic and the life of a storage battery greatly by making the outer frame bone side of outermost adjacent packing spaces, which are surrounded by frame bones the center lines of which are at an acute angle (theta) of between 0 deg. and 50 deg. to the rolling direction of a thin plate, to be a plain part continuous with said outer frame bones. CONSTITUTION:The angle between the center line (mn) of a test piece and a line (pq) which is parallel to the rolling direction (RD), is supposed to be theta. Various test pieces are prepared by varying the angle (theta) from 0 deg. to 90 deg., and the yield strengths (alpha0, 2) of the test pieces are obtained by carrying out a tension test. As a result of such a test, it was recognized that the yield strength of the test piece almost doesn't decrease when the angle (theta) is varied from 0 deg. to almost 50 deg. and that it decreases as the angle (theta) is varied from 50 deg. close to 90 deg.. Therefore, the angle (theta) is restricted to between 0 deg. and 50 deg.. An active-material- packed space 53 located in the outer peripheral part of a base plate is surrounded by frame bones 51 and 52, and frame bodies 54 and 55 which are continuous with an outer frame bone 56. In addition, the center lines 51' and 52' of the frame bones 51 and 52 are made at an acute angle (theta) of 30 deg. to the line (ab) which is parallel to the rolling direction (RD) of a thin lead-alloy plate.

Title: Image recording device
Inventor: SATOU KOUJI
IPC: G03G21/00
Filed: 1984-02-29
Abstract: PURPOSE:To reduce the curl of a sheet after discharge and to improve transfer and separation during both-surface printing operation by supplying vapor to a recording member (sheet) discharged from a heat fixing device. CONSTITUTION:While the temperature of the sheet 9 discharged from a fixing device 16 is high to some extent, air containing vapor whose temperature is lower than said temperature is at the shrinking surface side of the sheet 9. Then, the sheet 9 is higher in vapor pressure at the shrinking surface side than at the expanding surface side. Further, the amount of vapor from the sheet 9 is prevented from becoming excessive to balance with the amount of water supplied to the shrinking surface side of the sheet 9, and moisture is supplied to the shrinking surface side to correct curl. The expansion of the sheet due to moisture supply is utilized only to supply vapor to the sheet which shrinks owing to curl, and an extreme increase in the surface resistance of the sheet after the 1st heat fixation is prevented to perform the 2nd image recording excellently.

Title: Surface acoustic wave device and its frequency characteristic adjustment method
Inventor: UU HOKUHOA
IPC: H03H9/25
Filed: 1995-02-27
Abstract: PURPOSE: To set the center frequency of a surface acoustic wave device to a desired frequency. CONSTITUTION: An insulating film 20 and a ferromagnetic thin film 21 are formed on a interdigital transducer IDT 15 on a piezoelectric substrate 11. The piezoelectric substrate 11 is mounted on, e.g. a ferromagnetic stem and a static magnetic field is applied to the piezoelectric substrate 11 in the vertical direction. The ferromagnetic thin film 21 and the stem are magnetized permanently by a static magnetic field and the surface pressure of the piezoelectric substrate 11 is increased by the magnetic attractive force. Since the film 21 and the stem are magnetized permanently, the magnetic attractive force is left between the ferromagnetic thin film 21 and the stem even when they are released from the static magnetic field and the surface pressure of the piezoelectric substrate 11 is adjusted constant at all times.  The propagation speed of the surface acoustic wave is changed by the increase in the surface pressure to obtain a desired center frequency.
