Title: Method of detecting bump position
Inventor: IWATA HISAFUMI
IPC: H01L21/60
Filed: 1988-09-19
Abstract: PURPOSE:To detect a bump position absolutely necessary to realize an automatic alignment method for face-down bonding steadily by a method wherein the surface of a board having a contact terminal with a bump is lit obliquely to create a shadow region on the side of the bump and its picture detection is carried out vertically from the above and its projected waveform ia obtained and analized. CONSTITUTION:If a solder bump 1 formed on a board 2 is lit obliquely along the direction shown by arrows in the figure, the lighting light is blocked and a shadow region 3 is created behind the bump 1. As the surface of the board 2 has a light scattering property, it can be detected brightly in a normal state but the surface in the shadow region 3 near the bump 1 becomes dark. The shape of the shadow region 3 when the bump 1 is looked down from the above directly in that lighting state depends upon the diameter and height of the bump 1 and the incident angle and direction of the lighting light and the center axis 23 of the shadow region 3 in parallel with the incident direction of the lighting light passes through the center position 24 of the bump. In other words, if the respective center axes of two shadow regions created by two lighting lights applied from two different directions, (forming a right angle) are obtained, the position of the bump can be determined.

IPC: G01S7/32
Filed: 1986-09-29
Abstract: PURPOSE:To accurately detect a signal, by discriminating a clutter region by an amplitude level obtained by averaging the level of a normal video signal at every unit region and automatically selecting the video signal. CONSTITUTION:A normal video signal is inputted to a terminal 1 to be converted to a digital signal by an A/D converter 6 and said digital signal is sliced at a slice level 2 by a slicer 3 to obtain a hit signal. The MTI video signal from a moving target (the video signal detecting the moving target) is inputted to a terminal 5 to be converted to a digital signal by an A/D converter 7 and said digital signal is sliced at a slice level 8 by a slicer 9 to output a hit signal. The data obtained by converting the normal video signal by the A/D converter 6 is inputted to a video amplitude average level calculation circuit 10 and the average level at every fan-shaped unit region due to the vectorial angle signal and distance signal obtained from a terminal 12 is calculated in a memory circuit 11. Next, an antenna is rotated to successively read data which is, in turn, judged by a judge circuit 13 to output a selection signal and a switch 14 is changed over to the slicer 3 or 9 and the MTI video signal is employed in a clutter region high in an amplitude level. By this method, the erroneous detection of the target can be reduced.

Title: Magneto-optical recording medium
Inventor: TAKAHATA TSUTOMU
IPC: H01F10/16
Filed: 1992-08-10
Abstract: PURPOSE:To improve thermomagnetic recording characteristics by laminating an artificial lattice film obtd. by alternately laminating CoNi alloy layers and Pt layers and a film consisting of a rare earth metal and a transition metal and carrying out magnetic coupling. CONSTITUTION:An artificial lattice film 3 consisting of alternately laminated layers of an element of the Pt group and a transition metal and a film 4 of an alloy of a transition metal with a rare earth metal are laminated. Thermomagnetic characteristics can be improved by utilizing exchange coupling force by which the directions of magnetization of the transition metals in the two magnetic films are made parallel to each other at the interface between the magnetic films. When a CoNi/Pt lattice film is used as the lattice film 3 with CoNi obtd. by adding Ni to Co, interfacial magnetic wall energy is increased and an exchange coupling magnetic field can be increased without lowering readout performance.

Title: Drain pan structure for coil type water cooler
Inventor: SHIGETA KOJI
IPC: F25B39/02
Filed: 1990-09-05
Abstract: PURPOSE:To minimize the size of drain pan, hence save materials, and reduce cost and weight by laying out the drain pan properly to the shape of coil and moreover mounting a coil type water cooler assembled in one piece with the drain pan when the cooler must be fixed with a fixing plate. CONSTITUTION:In a coil type water cooler 1, heat exchange takes place between the water flowing in an outer tube 2 and the refrigerant flowing in an inner tube 3 and cooled water is obtained by way of heat exchange. In this process where the cooled water is obtained, the outer surface of the outer tube, where cooled water is flowing, is turned to a temperature equivalent to the temperature of the cooled water and drops to the dew point temperature of air around the outside and below, which produces dew condensation on the outer surface of the outer tube 2 and the dew drops. The water is collected in a drain pan 4 formed along the coil type water cooler 1 and flows down along the inclination of the coil shape and it is discharged from a drain port 7 at the lowest elevation. Furthermore, since the drain pan 4 is laid out between the coil type water cooler 1 and a fixing plate 5, it is assembled in one piece by a fixing bad 6. This construction makes it possible to minimize the side of the drain pan and enhance the efficiency of assembly work since both the water cooler and the drain pan can be assembled in one piece.

Abstract: PURPOSE:To extend the life of a valve body and prevent the damage of ceramic plate by covering the top end part of the valve body with ceramic plates, and fixing the ceramic plates to base plates through fixing pins. CONSTITUTION:The top end part of a valve body 4 is covered with ceramic plates 14 to suppress the abrasion of the top end part of the valve body 4.
