摘要： PURPOSE:To decrease series resistance and to obtain a fine semiconductor device resistant to the soft errors by external noise or alpha rays by taking out a cathode electrode from the periphery of an anode. CONSTITUTION:A contact hole for cathode is made in a ring shape using potoetching technology on a silicon dioxide 21. After this, polycrystalline silicon 8 is made to cover the contact hole, and is doped with phosphorus, and is heat- treated to form an N-type diffusion layer 11. After this, silicon dioxide 10 is provided, and contact holes for an anode and others are made at silicon dioxides 6 and 21. Hereupon, the contact hole for an anode is located inside the contact hole for a cathode, and is arranged so that the distance between both contact holes may be equal. Next, a silicide layer 14 is provided at the surface of the anode. After this, an Al electrode is made, and a semiconductor device, which is great in resistance to external noise and small in series resistance, is realized.

摘要： PURPOSE:To produce a large-chip-scale integrated circuit available for a memory or the like with almost equal masks in number to that of subchips, by classifying a large chip into a plurality of subchips that is small enough to be exposed with one mask, and using a common mask to the subchips in almost all steps. CONSTITUTION:For instance, a large scale chip 10 measures W1 by h1, and is too large to be exposed with one mask when a conventional exposure apparatus is used. The chip 10 is classified into three regions a1, b1, and b2, and the regions a1 and b1 are assumed to have an equal or almost equal pattern and the region b2 has a quite different pattern from these two patterns. Then, the regions a1 and b1 are grouped into one subchip B, and the regions b2 and a20 into one subchip A. The region a20 is not essentially necessary, but is added in order to make the shapes of chips A and B in common. A common pattern is used for both the chips A and B in almost all steps from the beginning, and a differentmask is only used for last few wiring-system steps.

摘要： PROBLEM TO BE SOLVED: To improve operation efficiency and decrease errors in constructing the logical network by selecting desired terminals by using menus which are registered by attributes by grouping terminals when the logical network is constructed. SOLUTION: Software performs retrieval from a table to automatically generate selection menus 6-4 and 6-5. To generate the terminal selection menu of a speech network 6-4, it is found that a terminal which can be set in a speech field first has an attribute of PBX. Then it is found from the table that there are private branch exchanges PBX-1, PBX-3, and PBX-2 having node numbers 1, 3, and 4, and this result is displayed 6-4. As for a data network, a selection menu 6-5 can be generated similarly. Therefore, a user specifies terminals out of those selection menus 6-7 and 6-7 and sets them in logical network definition windows 6-8 and 6-9 to eliminate the need to search for a logical network from physical 6-1.

摘要： PURPOSE:To embody a device which can conduct an interaction between each person whose language is different from each other and between a person and a machine without making an interpreter of sign language, etc., always reside, so that it is not suspended by an erroneous translation or a misunderstanding, and does not come to a standstill. CONSTITUTION:An interactive information management part 18 records an interactive career of a sound listener and an auditory sense handicapped person. When a standstill is generated in an interaction between the sound listener and the auditory sense handicapped person, it is switched to a conversational form executed through a sign language interpreter by a mutual agreement of both of them. A communication management system 19 can allow the sign language interpreter to access the career of the interactive information management part 18, and also, switches ports 11, 12 and 13 to such a form as a conversation by three persons can be executed, based on an instruction of the sign language interpreter.

摘要： PURPOSE:To lessen supply power to heaters at the time of temperature control in the vicinity of a room temperature and to decrease the consumption of liquefied gas in a sample stage, in which a sample arranged in a vacuum is subjected to temperature control at a low temperature by the balance of heat between the heaters and a cooling medium, by a method wherein the liquefied gas and gas for cooling use are subjected to selection and are led in the interior of the cooling tank of the sample stage. CONSTITUTION:A temperature control is performed by the balance of heat between a refrigerant, which is put in a cooling tank 6, and heaters 7. The tank 6 is formed into such a structure that liquefied gas and low-temperature cooling gas are subjected to selection and can be put in the interior of the tank 6 as the refrigerant. When a sample 5 is subjected to temperature control at a low temperature, the liquefied gas is selected by a valve 11 and the liquefied gas is directly introduced in the interior of the tank 6. Here, when the sample is subjected to temperature control at -120 deg.C, 300 W is needed. In case the sample is subjected to temperature control at a temperature of -100 deg.C or higher, the cooling gas is selected by a valve 11 and is led in the interior of the tank 6. The gas passes through the interior of a gas cooling tank 13 arranged in the midst of a piping 12 and is directly cooled with liquefied gas 14 in the tank 13.
