Inventor: SHIYUMITSUDO HANSUURUDOBUIHI
IPC: G01N30/06
Filed: 1990-09-20
Abstract: PURPOSE: To determine the isotope compsn. of the element contained in a sample by allowing carrier gas containing no selected element to flow to a heating catalyst (Pt.Rh alloy of about 1200 deg.C) reactor and pyrolyzing the sample in the reactor. CONSTITUTION: Carrier gas containing no selected element is allowed to flow through a heating catalyst reactor 2 and the flow of the carrier gas is introduced into a sample before it enters the reactor 2 so that the sample is pyrolyzed within the reactor 2. All of C in the sample is converted to an element C precipitated within the reactor 2 and all of O in the sample is reacted with the element C to be substantially perfectly converted to CO and all of H and N in the sample are substantially perfectly converted to molecular H and molecular N. At least a part of the gas generated in the reactor 2 is transmitted to a mass analyser 4. On the basis of the measurement of the mass analyser performed with respect to CO, molecular N or molecular H, the isotope compsn. of at least one element selected from a group consisting of O, N and H in the sample is determined.

Abstract: PURPOSE:To miniaturize a circuit and to accelerate a response speed by connecting the source follower output of nMOS to common output and generating the maximum value of the input of the respective nMOS at the common output. CONSTITUTION:This maximizing circuit is composed by parallelly connecting the plural nMOS T1-T3 and input voltages (x)-(z) are inputted to the nMOS T1-T3.

IPC: C25D17/12
Filed: 1985-11-12
Abstract: PURPOSE:To prevent the generation of a spark when large current is supplied by forming energizing bar liners to contact anode electrodes into a brush shape. CONSTITUTION:The anode electrodes 20 formed of zinc, etc., are placed on the two energizing metallic bars 21, 22. The sectional shape of the energizing bar liners 23, 24 of the respective bars 21, 22 is formed into the brush shape. The energizing bars 25, 26 for fixing the liners 23, 24 are held by holders 27, 28 coated with rubber lining.

Abstract: PROBLEM TO BE SOLVED: To totally enhance the communication efficiency for a facsimile equipment having a memory reception function/a direct reception function that directly prints out data on recording paper when the data quantity of a received image in a lot and that receives data in a memory when the data quantity is a little. SOLUTION: While storing received image data sent from a transmitter side to an audio image storage device 15, an idle capacity of the audio image storage device 15 is checked at the same time. When a little image data are received, it is discriminated that much idle capacity is in existence, the reception system is left unchanged and the communication is finished. When a lot of image data are received, it is discriminated that remaining idle capacity is a little, the reception system is forced to change to the direct reception system and the communication is abnormally terminated. Since an opposite party discriminates occurrence of a communication error, the opposite party sends data again. Since the direct reception system is selected at the receiver side, the receiver side prints out the received image data on recording paper.

Filed: 1985-11-12
Abstract: PURPOSE:To reduce the recess from a sealing resin to the chip of a resin sealing type semiconductor device by forming a cavity between an organic matter for enclosing the chip and the sealing resin by using the difference of the thermal expansions of both the organic matter for enclosing the chip and the sealing resin. CONSTITUTION:The whole is sealed with a sealing resin 1 such as epoxy resin over an organic matter 6 for enclosing a chip such as ethylene-propylene rubber which covers the chip 2 and a die pad 4. In this case, the sealing is made normally at a temperature 160-180 deg.C. At this time, the organic matter 6 for enclosing chip and the sealing resin 1 are made adherent state and if these are cooled, the interface of the organic matter 6 for enclosing chip and the sealing resin 1 is separated by the difference of the thermal expansions of both and a cavity is formed. In this case, if the coefficient of thermal expansion of the sealing resin is smaller, the difference of shrinkage with the organic matter for enclosing chip is made larger and a cavity can be formed easily. The existence of the cavity prevents the inner chip being affected by the stress from the sealing resin due to a thermal shock, a hardening shrinkage, etc. and a highly reliable resin sealed type semiconductor device is obtained.
