Title: Ceramic chip mounted product
Inventor: KONO YASUHIKO
IPC: H05K3/34
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To avoid concentration of stress and prevent breakage of a ceramic chip, by forming an angle formed by a lower surface of a ceramic chip mounted on a land which is an electrode at a substrate side and a connection material obtuse. SOLUTION: Electrodes 2a, 2b of a ceramic capacitor 2 are fixed to lands 1a, 1b which are electrodes provided to a substrate 1 by a connection material such as solder 2c in a lower surface of the substrate 1 at a back fillet angle α. Since a lower surface of the ceramic capacitor 2 and the lands 1a, 1b are in parallel, the back fillet angle α is an angle formed by a lower surface of the ceramic capacitor 2 and the solder 2c. Therefore, concentration of stress can be reduced by making the back fillet angle αobtuse. As a result, breakage of a ceramic chip can be avoided.

Abstract: PROBLEM TO BE SOLVED: To improve the positioning precision of a test probe and a test pad at the time of checking a TAB and to accelerate a positioning speed by allowing a semiconductor chip to shift the stop position of a tape carrier (TAB tape) that is bonded in accordance with a correction signal which corresponds to deviation value. SOLUTION: A recognition mark is provided at an edge part of a product part in a TAB tape 10 that is carried on a test probe stage 1. The deviation value of a recognition mark position is calculated when a CCD camera 20 monitors the recognition mark and it is subjected to image processing by using an image processor 21. The processor 21 sends calculated deviation value to a piezo element controller 22, further calculates a moving amount of a test probe part 2 in an X-Y direction which is needed to correct the deviated value, applies voltage that corresponds to it to actuators 15 and 16 and corrects the position of the part 2, i.e., the position of a check part of the product part so that the recognition mark may be a prescribed position.

Inventor: MIYAKE TOMIO
IPC: F04D27/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To correct variation of rotation frequency caused by an individual difference of a fan motor without increasing a cost by previously correcting a current flowing in the fan motor in such a manner as that a deviation between current values obtained in comparison with current-rotation characteristics of a fan motor having no variation can be kept within an allowable range.

When a fan motor having ideal current-rotation characteristics is rotated in the state in which no resistance is exerted on an air blowing path, a standard current value flowing in a standard motor is compared with a detection current value flowing when the fan motor 5 to be actually incorporated and controlled is rotated in a standard state. Subsequently, a current flowing in the fan motor 5 is previously corrected in such a manner that a deviation between both the current values can be maintained within a predetermined value.
