Title: Brazing filler metal for lead pin
Inventor: IWAI SHOZABURO
IPC: B23K35/30
Filed: 1992-10-19
Abstract: PURPOSE:To assure the uniform height of lead pins without the irregularity thereof by preparing the brazing filler metal for lead pins contg. Au in a specific range and consisting of the balance Sn. CONSTITUTION:This brazing filler metal 5 for lead pins consists of 78 to 79.5% Au and the balance Sn. The brazing filler metal 5 for lead pins having such component compsn. is mostly the eutectic structure of the Au and the Sn and slightly Sn-rich crystals appear therein but the Sn rich crystals are fine and, therefore, the irregularity in the height at the time of brazing the lead pins 1 does not arise. Substrates or the lead pins, etc., are often subjected to Au plating in order to improve brazer flow or to improve reliability. The Au of the Au plating component is taken in to form the AuSn eutectic structure at the time of soldering even if the brazing filler metal 5 for lead pins has the Sn-rich crystals and, therefore, there are no troubles at all.

Title: External-appearance evaluating apparatus for melon
Inventor: TOKI HARUMITSU
IPC: G01N21/85
Filed: 1991-10-25
Abstract: PURPOSE:To eliminate the dispersion in evaluation for the width of meshes and to save the man-hours for the evaluating work by extracting the abnormally thick part of mesh width from the photographed image of a melon, and evaluating the mesh width of the melon based on the extracted result. CONSTITUTION:A melon (a), which is lit with a light source 1, is photographed with an image input device 2. An image processing device 4 performs the binary coding of the picked-up image and extracts the meshes of the melon (a). The matrix size of a space filter is determined so as to extract a part exceeding a specified width among the meshes. The filtering is performed by using the preset filter. The part of the meshes, wherein the luminance is not changed, is made to be a 0, and the part, wherein the luminance is changed, is made to be a 1. Thus the binary coding is performed. In this way, the part of the meshes exceeding the specified width is extracted. The image, whose size is less than the specified value is removed from the image. The total area of the image after the removal is measured. The area if compared with the specified value beta. When the area is wider (narrower) than the value beta, it is judged that the distribution of the wide parts is large (small) in the meshes.

Abstract: PROBLEM TO BE SOLVED: To prevent a third person from arbitrarily adjusting a screen by invalidating the operation of a specified key based on the depression of a prescribed key which is simultaneous with the supply of power. SOLUTION: The operation of a specified key is invalidated based on the depression of a prescribed key which is simultaneous with the supply of power. Relating to the device, a control part 11 detects driving current Icc from a power circuit 17 and initializes various flags if it judges the depression of a power key 8. The control part 11 judges whether the prescribed key is depressed at the same time as the supply of the power key 8 (a menu key and a selection key are simultaneously depressed, for example). Relating to the device, a key locking state flag in a storage part 15 can be changed when the menu key and the selection key are depressed at the same time as the depression of the power key 8. When the flag is in an on-state, a screen adjusting processing is not executed.
