Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To substantially extend the service life of a power supply port and enable a local illumination device to be used over a long period of time without requiring a new power supply port by using an LED with its less power consumption as an illumination means. SOLUTION: A local illumination device is provided with an optical sensor means 1 for judging peripheral brightness, a battery means 2 which does not require AC100V plug socket, an illumination means 3 whose power sources are the battery means 2, and a human sensing sensor means 4 for detecting the presence or absence of a human body in the periphery. And, the means 3 is actuated only when the periphery is dark and when the presence of the human body in the periphery is detected, and power consumption of the means 3 can be reduced by using an LED for the means 3. Therefore, since the service life of a power supply port can be substantially extended, the device can be used over a long period of time without requiring a new power supply port.

Title: Mounting structure and formation thereof
Inventor: SOEJIMA KOJI
IPC: H05K1/14
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To obtain a mounting structure that absorbs distortion by joining together the electrodes on boards to be mounted using strips of conductor, and thereby providing soldering sections with a certain degree of freedom through deflecting deformation. SOLUTION: Boards 6, 7 are mounted on each other in a high-temperature atmosphere using solder 3, and then cooled down to ordinary temperature. At this time, distortion in the boards 6, 7 is exerted on the connections 5a of conductor strips 5 as stress because the ceramic board 6 is different in coefficient of thermal expansion from the board 7 made of a different material, such as glass epoxy. This stress separates the connections 5a of the conductor strips 5 from the board 6, and thus distortion in the board exerted on the connections 5a is absorbed. Thus all distortions produced from the heat histories of the boards 6, 7 mounted, are absorbed by deflecting deformation in the conductor strips 5. The connections 5a are separated from the board 6 by distortion produced when the boards 6, 7 are cooled down to ordinary temperature, and will not be broken. This provides highly reliable connection.

Abstract: PURPOSE: To make the contents of the weight displayed easy to understand to the customers by providing two lamps which go on respectively when the weight displayed is minus and when it is plus where tare amount has been set.  
     CONSTITUTION: When a tare amount is set and tare substraction is performed in a key matrix 5, a display driving circuit is driven by a microcomputer 4 and the minus value of the weight displayed in a display tube 8 is displayed and a tare subtraction lamp 9 goes on. Next, when the object to be weight is placed on a weighing pan, the value having subtracted the tare amount from the weight count data from a counter 6, i.e., the net weight of the object to be weighed, is displayed. The weight displayed becomes a plus value and a net weight lamp 10 goes on. Hence, the weight displayed while the net weight lamp 10 is going on is a net weight and lighting of the tare subtraction lamp 9 indicates that there is no weighing object on the weighing pan.
