Filed: 1989-05-29
Abstract: PURPOSE:To achieve an expansion of an effective detection area by providing an obstacle at a part within a detection area to vary a dose of infrared rays to an infrared ray detector. CONSTITUTION:A window frame 4 having circular view window 3 opened therein is provided to determine a detection area 2 of a pyroelectric sensor 1 and a window plate 5 to close the window 3 from inside. The window plate 5 is made of infrared transmission resin and a light shielding tape 7 is stuck linearly at the center of the surface thereof as obstacle to intercept infrared rays.

Title: Coulometric analysis method
Inventor: HAMAMOTO OSAMU
IPC: G01N27/42
Filed: 1989-05-29
Abstract: PURPOSE:To perform electric analysis highly accurately even if a component which interferes with the specimen in a sample is present by performing coulometric analysis for the sample in which the component for decomposing the specimen is added and for the sample wherein the component is not added. CONSTITUTION:A sample is imparted or injected into a detecting electrode which comprises a conductive porous body and in which electrolyte is impregnated so that it does not flow out. Coulometric analysis of the specimen in the sample is performed. At this time, the coulometric analysis is performed for the sample wherein a third component for decomposing the specimen is added and for the sample wherein the third component is not added. The specimen is determined based on the difference between the measured values. Since the analysis method is an absolute determining method, the third component does not give effects on the detecting sensitivities of a standard sample and the measured sample even if the third component is added, and deviation in the measured values is not formed.

Filed: 1987-05-29
Abstract: PURPOSE:To perform a test twice as fast as conventionally, by making a second contact area equal to or larger than a first contact area so as to lower current density on the second contact and making an applied voltage half. CONSTITUTION:A contact chain 100 is formed by disposing diffusion layers 30 and Al layer wiring matters on a semiconductor substrate. A pad 1 for flow-in of a stress current and a pad 2 for flow-out of the stress current are disposed on both ends of the contact chain 100, respectively. A size of each contact 11, where the stress current flows from each wiring matter to each diffusion layer 30, is made to be that of an evaluated object, that is, 1.0mum or less. Each contact 10, where the stress current contrarily flows from the diffusion layer 30 to the wiring matter, is made to be e.g., ten times or more as large as the contact 11. A breakdown of junction between the diffusion layer 30 and the substrate below the contact 11 is evaluated by applying the current stress to the pattern of the contacts 10 and 11. Hence this test is performed twice as fast as conventionally.
