Title: Detection of extra ball
Inventor: SAKAI TADAHIKO
IPC: H01L21/60
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide an extra-ball detecting method, which can avoid erroneous mounting of the extra balls, which are excessively attached to the lower surface, on a work when many conductive balls are held at the lower surface of a mounting head and mounted on the work. SOLUTION: A mounting head 22 sucks solder balls 1 as the conductive balls stored in a container in the vacuum state to the suction hole of the lower surface, picks up the balls and moves the balls toward a work. At the halfway, the lower surface of the mounting head 22 is observed with a camera 30, and the image of the surface is obtained. The solder ball 1 is the spherical body of the metal having a glossy surface. When light is applied from below, only the light applied on the center is intensely reflected downward and incident into the camera 30. Therefore, only the center of the solder ball 1 is brightly observed. At this time, by analyzing this image by the well-known image processing technology, the presence of the extra ball can be simply detected.

Title: Photoelectronic device
Inventor: SASAYAMA ATSUSHI
IPC: H01S5/00
Filed: 1985-02-25
Abstract: PURPOSE:To improve the reliability of a device by increasing the mechanical strength of an optical fiber at a package fitting part and also preventing humidification deterioration at thepackage fitting part. CONSTITUTION:The optical fiber is fitted to the package consisting of a stem 2 and a cap 3 by utilizing a guide 14. In this case, the part of a core 18 extending to the hollow part of the guide 14 is surrounded with a glass pipe 24 and resin 23 and held fixedly. Consequently, even if the core 18 is stressed thermally owing to a difference in coefficient of thermal expansion between plastic and quartz, no bending occurs because the part of the core 18 is held and guided with the resin 23, thereby preventing the breaking of a wire due to bucking. Further, the core 18 exposed at the fitting part of the optical fiber 10 is protected by the resin 23, so the corrosion of the core 18 due to water in outside air is prevented. Thus the reliability of the device is improved.

Title: Karman vortex flowmeter
Inventor: NAKAGAWA WATARU
IPC: G01F1/32
Filed: 1990-02-15
Abstract: PURPOSE:To suppress the effect of external vibration and to improve measuring accuracy by providing a main part having the free end part, a hollow part which is located in the inside of the main part and has the bottom that is opened at the free end part and a communicating hole for communicating the hollow part and the outside. CONSTITUTION:The cross section of a vortex generating part 2a has an equilateral trapezoid. A columnar body 9 having the cross section of an isosceles triangle is provided so that the base is positioned at the upstream side with respect to a flowing direction Q in close proximity to the long base of the part 2a. The vortex generating part 2a and the columnar body 9 constitute a Karman vortex generating body in a broad sense. The vortex generating part 2a corresponds to the main part for generating vortex. The columnar body 9 corresponds to the secondary part for supporting the generation of the vortex. The vortex generating part 2a has the tubular structure having a hollow part 2c in the inside. Therefore, its mass is small, and inertia force when external vibration is received becomes small. Therefore, the SN ratio is increased, and sensitivity and accuracy in measurement are improved. Since the hollow part 2c is filled with fluid to be measured, the vortex generating part 2a receives the same fluid pressure from the inside and the outside. Therefore, mechanical deformation and the decrease in mechanical strength can be prevented. A hole 2b prevents the remaining of bubbles in the hollow part 2c.
