Title: Brazing method for spectacle part
Inventor: KIMURA RYOJI
IPC: B23K1/00
Filed: 1988-03-31
Abstract: PURPOSE:To improve the beauty of a joining part and to uniformize the thickness in joining by preforming a brazing filler metal layer in the specified amt. on one part of the part joining face and joining the brazing filler metal layer to the brazing face of the other part. CONSTITUTION:The jig 3 having the bottom face in the same shape as that of a joining face is prepd., the brazing filler metal 5 in an optional shape is arranged at the recessed part 4 thereof and the hinge 1 as for one part of a part is pressed and heated by locating it. In this case, the brazing filler metal 5 located on the bottom face is melted and a brazing filler metal layer 2 is formed on the joining face of the hinge 1. The hinge 1 is then set to the spectacle main body composed of a temple 7 and an armor 8 and heated in an electric furnace, etc., to execute brazing. The excessive brazing filler metal flowing-out is prevented due to the brazing filler metal layer 2 in a certain amt. necessary in advance being formed. The thickness of the joining part is uniformized because of the uniform thickness of the brazing filler metal layer 2 and the beautiful sight of the joining part is improved.

Title: Method of manufacturing package solid electrolytic capacitor
Inventor: TAKAMI KATSUHIRO
IPC: H01G13/00
Filed: 1995-04-05
Abstract: PURPOSE: To improve the production yield by collapsing a right or left side part of the top end of an anode lead terminal of an anode rod in the thickness direction to deform it in the width direction of this terminal. CONSTITUTION: When a capacitor element 3 inclines right to the center line of both lead terminals 1 and 2 at an angle exceeding specified allowable range, the right side part 1b of the top end of the terminal 1 is collapsed to deform it in the depth direction and expand in the width direction of the terminal 1 by lowering one variable punch C1 toward a fixed die B. This shifts an anode rod 5 to the left to correct so that the inclination angle can be within specified allowable range. When the capacitor 3 inclines left to the center line of the leads 1 and 2, the correction can be made as described above.

Title: Heat exchanger with fin
Inventor: OBATA MAKOTO
IPC: F28F1/32
Filed: 1984-04-20
Abstract: PURPOSE:To improve heat transfer rate in an air side heat transfer surface remarkably by decreasing the temperature boundary layer of the heat transfer surface and a water stagnating zone in the after-stream of the heat transfer tube by the configuration of the fin. CONSTITUTION:When airstream flows into arrow sign direction, the airstream, which tried to separate from the surface of the heat transfer tube at the stagnation point thereof, is prevented from separating by wavy flow regulating grooves 6 provided on the fins 1 around the heat transfer tube 2 and flows convergently along the surface of the tube 2, therefore, the water stagnating zone 4 in the backwash of the tube 2 is decreased remarkably. Thereafter, the airstream is converged by wavy flow regulating groove 6. The airstream passes also through louver-like cut 7, having opening part 8 in the direction of row at only the upstream side on the surface of the fin 1 in the backwash of the tube 2, a very thin temperature boundary layer of the airstream is formed at the louver-like raised pieces 7, then, the airstream changes the direction so as to flow through other fins 1 and collides against the center of the heat transfer tube in the direction of other row. By a mixing effect, effected by the louver-like cut 7, the flow of air affects the other fins and tubes respectively and the efficiencies of heat exchange are improved mutually.

Title: Image forming device
Inventor: SATO HITOSHI
IPC: G06F3/12
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To make it easy to specify the cause of abnormal operation in such a case by taking an operation diagnosis of a mounted memory in an idle period wherein a task needed for image formation temporarily stops. SOLUTION: A free memory area consisting of a prescribed number of bytes is obtained in an extension RAM 20. The memory capacity which is obtained here is about several K bytes exceeding the capacity of a cache memory in a CPU 11. Then it is judged whether or not the addresses of the obtained free memory are proper. At this time, when it is judged that the addresses are not proper, that is displayed at an LCD display part 15. When it is judged that the addresses are proper, data which are written are read out of the same memory cells at the same timing with ordinary operation and it is checked whether the data are all 0×55 (55 in hexadecimal notation). At this time, if there is even one piece of different data, the LCD display part 15 displays the abnormality of the extension RAM 20.

Title: Mr imaging method
Inventor: SHIMIZU KIMIHARU
IPC: G01N24/08
Filed: 1988-03-31
Abstract: PURPOSE:To effectively suppress a motion artifact even where there is complicated movement, by reversing the reading inclined magnetic field applied when an MR signal is generated in a half echo method within a short time immediately before the time of the center of the MR signal. CONSTITUTION:In a pulse sequence, Gz is an inclined magnetic field for slice selection, Gy is an inclined magnetic field for phase encoding and Gx is an inclined magnetic field for reading and the intensities of said magnetic fields are respectively inclined in the Z-, Y- and X-directions of three orthogonal axes. The inclined magnetic field Gx for reading is reversed immediately before the center of an echo and the tine integrations of respective pulses 1-4 are same and these four pulses are applied within a short time DELTAT. By this method, phases are aligned and a motion artifact is suppressed. Since this reversal of the inclined magnetic field is performed within a short time immediately before the center of an NMB signal, there is no great difference even if handling is performed so as to be approximate to a constant speed and, therefore, the motion artifact to complicated movement can be substantially and effectively suppressed.
