Title: Method and device for testing solder wettability
Inventor: SHIMOKAWA HIDEYOSHI
IPC: G01N25/02
Filed: 1994-06-14
Abstract: PURPOSE:To detect solder wettability of micro soldered parts and an area covered with a low-melting-point metal in microelectronic parts, etc., by placing a solder ball on a sample for heating and measuring the duration up to the beginning of molten solder expansion or its temperature. CONSTITUTION:For example, an Sn-Pb solder ball 20 of 3mm in diameter is put on a sample 16 and they are placed in a sample chamber 1, then the sample 16 and solder ball 20 are heated at a constant speed while replacing the sample chamber 1 with Ar gas. The behavior of the ball 20 on the heated sample 16 is converted into a video signal by a CCD sensor 10 through an observation optical system 9, and it is binarized by a picture processor 11, picture-recorded 12 and picture-motioned 13. A controller 8 automatically finds out the inclination per measurement time interval for solder expansion area, and determines a temperature where the increase in inclination becomes the maximum, as a starting temperature of wettability expansion and measures the temperature and duration up to the beginning of expansion. Thus, the area covered with a low-melting-point metal can be tested for its wettability.

Abstract: PURPOSE:To measure the air/fuel ratio at a high accuracy by a method wherein voltage between a pair of electrodes of an oxygen sensor is measured, a signal of the voltage is applied to a current source which runs current to ensure a specified voltage and the current value is measured. CONSTITUTION:A first electrode 13, an oxygen ion conductive solid electrolyte 14, a second electrode 15 and a gas diffusion layer 16 are provided on a porous substrate 12 of a gas diffusion layer to form an oxygen sensor 11. A heat generating body 17 is provided in the substrate 12. Then, the sensor 11 acts as oxygen pump depending on the oxygen partial pressure between a measuring gas and a reference gas. At this point, a voltage is generated between the electrodes 13 and 15 and the voltage E is measured with a voltage measuring means 18. A signal of the voltage E is transmitted to a current source 19 so tht the current value is adjusted with the current source 19 to keep the voltage E constant. The current value is measured with a current measuring means 20. Thus, the air/fuel ratio can be measured continuously from the air excessive side to fuel excessive side by running current to keep the voltage E at a specified value.

Abstract: PURPOSE:To easily construct a high-speed, effective, and efficient system by automatically erasing rules having rule numerical values smaller than a certain value when a series of inferences are terminated. CONSTITUTION:When a question is inputted from an input means 4, an inference means 3 sends the numerical value, which is given to a stored knowledge rule, to a temporary storage means 7. An operating means 8 adds one to the numerical value given to the knowledge rule stored in the means 7. This addition result is sent to a control means 9, and the means 9 updates the numerical value of the knowledge rule. A comparing means 11 compares the numerical value given to the knowledge rule stored in the means 7 with the numerical value stored in a storage means 10 on a basis of the operation of the means 9. A numerical value different from the initial set value of the knowledge rule stored in a base, for example, one is stored in the means 10. If the value in the means 7 is smaller than that in the means 10 as the result of comparison, the means 9 deletes this rule in a base 3.
