Patent JP-H1022621-A (JP)
Title: Reflow device
Inventor: SHIMIZU MAMORU
IPC: H05K3/34
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a reflow device which can surely heat and fuse the solder supplied to the junction between a substrate and an electronic part within a specified time. SOLUTION: The heating property at one face (26A) of a substrate (26) can be made almost uniform, because the velocity of the hot blast blown out of each hole (24A) of a wind velocity adjusting member (24) can be made roughly uniform, by having arranged a wind velocity adjusting member (24) where a plurality of holes (24A) geared to the opening positions and the wind velocity property of a hot blast supply means (22) are made, between the hot blast supply means (22) and the substrate (26). This way, a reflow device, which can heat and fuse the solder supplied to the junction between the board (26) and each electronic part (27) surely within a specified time, can be materialized.

Title: Hydrophilic polyurethane with excellent deodorizing effect
Inventor: KOSHIRO AKIRA
IPC: A61L9/01
Filed: 1987-08-05
Abstract: PURPOSE:To supply moisture steadily to display effect of a ferric compound deodorant without dissolving the deodorant in the moisture by including the deodorant in a hydrophilic polyurethane. CONSTITUTION:A ferric compound deodorant is included in a hydrophilic polyurethane, for which an anionic polyurethane is used. It is preferable that the anionic polyurethane have a carboxyl group or a carboxylic salt group in its molecule and that its concentration be about 0.001-1.0 milli-equivalent/g. When the concentration of the carboxyl or carboxylic salt group is assumed to be A milli- equivalent/g, it is appropriate to contain 0.001XAXB-1.2XAXB milli-equivalent of the ferric compound in B g of a urethane resin. It is further appropriate to contain 50wt.% or more ethylene oxide units in the main chain. As it is possible to use a hydrophilic polymer in the solid form, moisture that enables the deodorant to exhibit its sufficient effect can be steadily supplied.

Title: Transducer array for surface acoustic wave
Inventor: NAKAMURA KENJI
IPC: G02F1/33
Filed: 1986-08-25
Abstract: PURPOSE:To obtain uniform surface acoustic wave intensity over a wide frequency range with low power consumption, by successively transmitting high-frequency signals to a transducer (IDT), whose natural frequency band matches the frequency of the signals, by means of circulators. CONSTITUTION:High-frequency signals produced by a variable frequency oscillator 11 are inputted to the 1st circulator 17 from an opening A of the circulator 17 after they are amplified by an amplifier 12 and further inputted to an IDT 6 from another opening B of the circulator 17 through the 1st variable phase shifter 14. When the frequency of the inputted high-frequency signals is within the natural frequency band of the IDT 6, surface acoustic waves (SAW) are excited from the IDT 6. When the frequency is outside the band, the signals are reflected by the IDT 6 and transmitted to the opening B of the circulator 17. Then the signals are inputted to the 2nd circulator 18 from the next opening C. Thus, the high-frequency signals from the amplifier 12 are transmitted to an IDT, whose natural frequency bands match the frequency of the signals, by means of the circulators in an almost no-loss state and converted into elastic surface waves.

SOLUTION: A restricting means 22 is equipped with a supporting holder 46, a blade 48 comprizing a rigid member which is supported by the supporting holder 46 and one side face of which is brought into press contact with a surface of a developing roller 16, an elastically energizing means 52 which is disposed in the supporting holder 46 and presses against the one side face of the blade 48 toward the direction that makes press contact with the surface of the developing roller 16, and a pressure releasing means 54 which acts on the elastically energizing means 52 so as to release pressing force of the elastically energizing means acting on the other side face of the blade 48. The restricting means 22 is assembled in a state that the pressing force acting on the other side face of the blade 48 is released.  Therefore a circumferential surface of the developing roller 16 is not damaged by the blade 48 when they are built into a development housing.

Title: Method for measuring roll alignment
Inventor: TOKUDA MASATOSHI
IPC: G01B21/00
Filed: 1981-12-09
Abstract: PURPOSE:To obtain the accurate roll alignment readily, by obtaining actually measured roll contact point coordinates in a specified coordinate system, correcting the values by the initial value of the central angle between the rolls, thereby correcting the slant angle. CONSTITUTION:A slant angle phi of a measuring instrument is detected. The contact point coordinates in the coordinate system determined by the configuration  of the measuring instrument is measured. The contact point coordinates in the coordinate system is corrected into the coordinates in the specified coordinate system. The contact point coordinates in the specified coordinate system are corrected based on the initial value of the central angle between the rolls, and the alignment of the entire roll group is obtained. In the case of, e.g., detecting the slant angle phi of the measuring instrument, the slant angle phi is determined by the slant angles of three rolls phi1, phi2 and phi3, when the three rolls are measured by the measuring instrument by one time. For example, the first slant angle is obtained by the expression in the Figure, where L is a distance between a pair of scales, and l is a distance from the end part of the scale to the contact point of the roll.

Title: Balancer for crankshaft
Inventor: NODA KUNIO
IPC: F16F15/24
Filed: 1986-08-26
Abstract: PURPOSE:To increase the inertia moment of a balancer by making the outer peripheral shape of the balancer of a crankshaft close to the envelope plane of the under surface of a piston around a crank pin through a connecting rod. CONSTITUTION:The shortest distance S from the center point Q of the piston pin 8 of a piston 3 at the bottom dead center position to the outer peripheral surface of a balancer 7 is obtained. Said distance S is the length which is obtained by adding the clearance 8 up to the outer peripheral surface of the balancer 7 from the under-surface of the piston 3 to the distance to the piston 3 under-surface from the center point Q. Then, the envelope plane as the locus of the point departing by the distance S from the center point Q of the piston pin 8 in the case when the piston 3 moves is obtained. Said envelope plane is used as the outer peripheral shape of the balancer 7. Therefore, the outer peripheral part of the balancer 7 can be spread without varying the length of a connecting rod 4, namely without increasing the whole height of the engine. Therefore, the inertia moment of the balancer 7 can be increased.
