Title: Observation device for hydrogen combustion experiment
Inventor: YONEYAMA TADASHI
IPC: G09B23/24
Filed: 1987-07-20
Abstract: PURPOSE:To obtain the subject device capable of experiments in a safe and secure manner by providing a combination of a suction port with a plug and a valve, an exhaust port with a valvular cap and an ignition electrode on a transparent soft vinyl pipe. CONSTITUTION:A syringe (piston) is inserted into an exhaust port 8, and a stringe containing a mixture of hydrogen and oxygen is introduced into a suction port 2. Next, the syringe on the exhaust port 8 side is drawn to drain air from transparent soft vinyl pipe 4. This causes the pipe to be dented. At that time, a valve 3 is pressed,which prevents the mixed gas from flowing in, and the depressed pipe indicates a fact that the air has been emptied (figure 2). In this state, a syringe containing the mixed gas is forcefully applied to send the mixed gas into the pipe 4 through the valve 3 (figure 3). After this, each syringe is pulled out and a plug 1 and a cap 10 are set in place. Then a spark is generated between and the electrode using a piezoelectric element resulting in the violent chemical reaction of hydrogen and oxygen into a high-temperature and high pressure gas. This gas leaks out of the pipe through a valve 7 with some remaining vapor being condensed under observation.

Abstract: PURPOSE:To make an accurate inspection by judging the direction of a semiconductor device with a relative difference in lightness between the ejector pin's trace and the molded surface. CONSTITUTION:Light is cast on a semiconductor device 12 at an angle from an illuminator 12 and a molded section 8 is photographed with a photoelectric transfer equipment 1. Then, an image of the molded section 8 is taken into a judgment equipment 15 to detect the lightness of the molded section 8, with the lightness detection range set for the trace of the ejector pin. A part between A and B is the ejector pin's trace and a part between C and D is the molded section. When these parts are converted to video signals, the A-B part comes out dark and has a lower lightness than the C-D part in a normally directed semiconductor device; there is a difference in lightness 11 between the A-B part and the C-D part in a normally directed semiconductor device. In the case of an abnormally directed semiconductor device, however, there is no difference in lightness between the A-B part and the C-D part. When the difference in lightness 11 is within the preliminarily set tolerance, the semiconductor device is judged good. When the difference in lightness 11 is not within the preliminarily set tolerance, the semiconductor device is judged no good.
