Abstract: PROBLEM TO BE SOLVED: To convert a quantitative key word into a qualitative key word. SOLUTION: A set of key word that are mutually synonymous is one record, and many records R1, R2,... are prepared as a thesaurus dictionary. Each record prepares a representative key word and a synonymous key word as a qualitative key word and a conditional expression key word as a quantitative key word. When a character string that is 'maximum blood pressure = 180' is given, a conditional expression key word that includes an attribute part that is 'maximum blood pressure' is sought through retrieval. A conditional expression that is 'maximum blood pressure > 150' is retrieved from the record R1, and a conditional expression that is 'maximum blood pressure < 100' is retrieved from the record R2.  When each conditional expression is substituted by a numeric value '180', and when a representative key word 'high blood pressure' of the record R1 whose condition is satisfied is outputted, a quantitative key word 'maximum blood pressure = 180' is converted into a qualitative key word 'high blood pressure'.

Title: Liquid phase epitaxial growth for compound semiconductor
Inventor: KISHI YUTAKA
IPC: H01L21/208
Filed: 1980-03-19
Abstract: PURPOSE:To resolve and remove slugs caused in the former step and prevent melt- back of the grown layer, by bringing, after the last layer is grown, the substrate into contact with melted liquid with similar composition to the melted liquid material. CONSTITUTION:A GaAs substrate 3 is set on a lower boat 1. In cisterns for melted liquid of the upper boat Ga 4 containing growth materials Al and As, and Ga 5 containing only As and not Al meant for cleaning liquid are respectively stored. In this unit for growth, the first slide of the boat performs an epitaxial growth by melted liquid 4. The second slide removes melted liquid 4 from the substrate. Thereafter melted liquid 5 passes on the substrate 3. Al, a component element for the growth layer, forms oxide, which turns to slugs and attaches to the surface of the growth layer. But the slugs are quickly removed by the contact with melted liquid 5. On the other hand, melt-back of the growth layer hardly takes place because Ga in melted liquid 5 is saturated by As.

Abstract: PURPOSE:To obtain an economical transmission line of high quality by transmitting a signal for the gain control of the main transmission circuit of an intermidiate repeater installed on a communication line by using the only the main transmission line, in an automatic gain controller. CONSTITUTION:In intermediate repeater 4, a communication signal has its line loss compensated by amplifying board 5. Variation in signal level is detected by control board 6 of receiving terminal station 2 and when the detection value exceeds a criterion, a control signal is sent out by using a low-frequency signal outside of a communication signal band. This control signal is separated from the communication signal by power separating filter board 8, inputted to control board 7, and detected, thereby controlling the gain of amplifier 5. The control signal branched by board 8 is transmitted through a low-pass circuit and supplied to main transmission line 3 by way of power separating filter board 9. The low-pass circuit is so constituted that signals will bypass amplifier 5 and will never be disturbed by directional amplifier 5.
