Title: Dc defect inspection system
Inventor: OGAWA SHUZO
IPC: G01R31/26
Filed: 1986-10-16
Abstract: PURPOSE:To detect pin disconnection or short circuit and an abnormal leak defect in an IC by generating a leak current by using a constant current source and measuring an applied voltage based upon the leak current by a voltmeter connected in parallel to the constant current source. CONSTITUTION:An operating voltage is applied between the power source pin 5 and ground pin 6 of the IC 3 with equivalent resistances RA and RB. The constant current power source 20 generates the leak current in the direction flowing from a signal pin 4 to be tested. The normal/defective state is divided into four areas by the value of the voltmeter 2. Current values of the respective parts are denoted as ia, ib, and i20 and, for example, when ib<ia and ib<i20, a wire between a chip and the pin 4 is broken on condition that ib=0 and RB=infinity . This constitution easily detects the disconnection of a wire and a short circuit of the signal pin 4 in addition to normal/defective decision due to the leak current.

Abstract: PURPOSE:To make it possible at home to bake a prefessional picture pattern on the surface of a porcelain, glass vessel, etc. by making a heat generating body arranged in a receiving section absorb microwaves emitted from a microwave oven to raise the temperature of the heat generating body to a high temperature and, by the radiation heat from it, baking picture patterns on the surface of a product on to its base body. CONSTITUTION:A vessel main body 1 is arranged in the cooking section of a microwave oven 2. When the switch of the microwave oven 2 is turned on, microwaves emitted in the microwave oven 2 invade with almost no absorption loss into the inside through the vessel body 3 formed by the outer walls of the vessel main body 1 and through its lid 4 and reach heat generating bodies 9 and 9a. Because said heat generating bodies 9 and 9a are constructed mainly of microwave absorbing materials such as carbon and carbon silicate, the heat generating bodies 9 and 9a reach a high temperature of about 900 deg.C in a short time by absorbing efficiently emitted microwaves and become red-hot. A product 5 is indirectly heated by the radiation heat from the heat generating bodies 9 and 9a. Accordingly, pattern pictures 11 and 11a are oxidized and baked on the surface of the basic body of the product 5.
