Title: Air suction and discharge device for outdoor airconditioner
Inventor: KIMURA KEIICHI
IPC: F24F3/044
Filed: 1989-01-11
Abstract: PURPOSE:To reduce the generation of vibration noise by connecting freely a T-shaped or cross-shaped manifold which is provided with an outside air intake port and exhaust port respectively open to an intake port and an exhaust port provided on the upper part of an airconditioner so that their shape may be selected freely. CONSTITUTION:A large-sized ventilation pipe is designed to form branch pipes 15 and 16 which are T-shaped, U-shaped or cross-shaped. Their respective ends are opened into a plurality of air suction ports 15' and exhaust ports 16'. which are directly connected with an upper air suction port 11 and an exhaust port 12 on an equipment body 1 or with an air suction port 13' and an exhaust port 14' of sound absorbing chambers 13 and 14 and then they are fixed respectively. Care is exerted to their connection method so that the orientation of the air suction port 15' and the exhaust port 16' are freely selected or changed to meet the environment and their positions round the ports. This construction makes it possible to absorb easily the optimum open air in any direction by changing the air suction port 15' on the suction side manifold 15 on one side. Therefore, an airconditioner can be installed even when the space is quite limited. In the case of exhaust air, this construction makes it possible to change a part of vibration noise leaked from the aforesaid exhaust port 16' in any direction by changing the exhaust port 16' of the exhaust side manifold 16 on one side.

Title: Chip inductor and manufacturing method thereof
Inventor: TAKATANI MINORU
IPC: H01F5/00
Filed: 1979-01-23
Abstract: PURPOSE: To reduce the size and thickness, by securing a shaped magnetic substance on a thin metal plate for inductance.  
     CONSTITUTION: A fluid magnetic substance mixture 11 is put on the top of a fixed ram 7 on a mold 5. A thin metal plate 1 whose outside termlnals are bent perpendicularly to a zigzag pattern is inserted. The mixture 11 is then inserted on the metal plate 1. A mold cavity 6 is closed with a movable column 10. Heating and pressurization are effected to perform prescribed molding. Since the magnetic substance 11 is an electric insulator, a means such as a bobbin is not needed. A product resulting from the molding is firm and handles easily. Because the product is shaped like a chip, its terminals can be directly soldered on a printed circuit board. This results in miniaturizing an electronic device.

Title: Apparatus for detecting through-hole defect
Inventor: MIYAZAKI KIKUJI
IPC: H05K3/00
Filed: 1988-01-13
Abstract: PURPOSE:To ensure the inspection of a defect in a through-hole with a simple combination of a heat source probe and an infrared-ray sensor, by comparing the temperature of the land of the through-hole part, which is measured with the infrared-ray sensor, with the temperature of a non-defective product, which is stored in a memory part. CONSTITUTION:A heat probe 2 having a constant temperature is positioned at a through-hole with an X-Y driving part 3 on one side of the land of the through-hole 9 in a high density printed wiring board 1. Then the probe is brought into contact with the land. At the same time, the image of the other land of the through hole 9 is formed on the surface of an infrared- ray sensor 5 through an image forming lens 4. The amount of the infrared rays is transduced into temperature. When a defect is present in the through-hole 9, the thermal resistance at that part becomes large. The temperature increase of the through-hole land, which is not in contact with the heat source probe 2, becomes gentle in comparison with the time when the defect is not present. Meanwhile, the transduced temperature is compared with the temperature of the good through-hole, which is stored beforehand in a memory part 6 and read out of it, in a comparing and judging part 7. When both values agree, it is judged as the good product. When both values do not agree with each other, it is judged as defective and the fact is outputted through an output terminal 8.

After it is amplified by an amplifier 9, it is calculated by the electrical signal and the corresponding scattered angle by an operation device 10 to obtain a forward scattered light intensity distribution. Then, the forward scattered light intensity distribution is measured repeatedly for at least once for the polymer liquid which changed with time, thus estimating the forward scattered light intensity distribution of the raw polymer liquid and obtaining a particle size and the dispersion property of particles.

Then, the first effective data in each section is subjected to a moving-average process, thereby to detect 3 the moving-average peak. The first effective data in a predetermined range within the effective data section centering at each of the moving-average peaks is detected as a second effective data. The second effective data is corrected 6 to a distance data from the circumference centering at the center of the work calculated 5 by the least squares method of the second effective data. The roundness of the work is calculated 7 based on the distance data. Accordingly, the peak-to-peak value can be obtained more correctly without eliminating the effective data.
