Abstract: PURPOSE:To automate a freezing-point measuring apparatus, wherein the sample liquid of a chemical product is injected into a sample liquid container, the liquid is stirred in a cooling bath with a stirring device, the liquid is slowly cooled, the change in sample temperature is detected with a thermometer, and the freezing point of the sample is measured, and to perform the highly accurate measurement. CONSTITUTION:The temperature hysteresis data of a sample S which is changed from the liquid state to the solid state are detected with a thermometer 18 and stored in a memory device 44. In an operating circuit 43, the freezing pattern of the sample S is identified based on the recorded temperature hysteresis data. The reference temperature point in the vicinity of the freezing point is set in response to the identified freezing pattern. A plurality of the measured temperature values are selected, respectively, in response to the freezing patterns based on the temperature hysteresis data measured before the reference temperature point and the temperature hysteresis data measured after the reference temperature point. The Points of intersections are operated as the freezing points by the resepctive regression expressions matching the selected temperature values. The freezing points are displayed on display devices 50 and 51.

IPC: G01S13/34
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain an FM-CW radar apparatus which can measure a desired distance range with a desired accuracy with using only one fixed filter. SOLUTION: The apparatus includes a VCO 15 controlled by a microcomputer 11, mixers 4a-4d for mixing an output of the VCO with echoes at an IF stage, and a BPF 16 as a fixed filter of a superior characteristic like a quartz filter. By selecting a desired signal frequency band, a desired distance range is measured with a necessary accuracy without increasing a process amount of data by the microcomputer 11. A linear FM modulated CW wave is irradiated to a target, the echo and a beat signal of a transmission signal are obtained, thereby generating an IF signal. The BPF 16 selects the echo from the target in a fixed distance range and generates a video signal. An A/D converter 10 converts the signal to digital data and the microcomputer 11 calculates a distance and a velocity.  Moreover, the microcomputer 11 changes an oscillation frequency of the VCO 15, thereby adjusting the signal in the desired distance range to agree with a pass band of the BPF 16.

Abstract: PURPOSE:To have input of the 2nd character at an optional position of a text by converting a 1st character into a 2nd character and calculating the difference between the number of bytes of a character saved in a saving memory and those of the 2nd character. CONSTITUTION:A KANA (Japanese syllabary)/KANJI (Chinese characters) converter 52 uses a character conversion dictionary 14 to convert the code of the 1st character into that of the 2nd character. The code of the 2nd character is stored in an area where the 1st character of a display memory 54 is so far stored and also displayed on a display device 1 as the 2nd character. At the same time, all bytes of the converted 2nd character are subtracted by a counter 56. In other words, the number of bytes of the 2nd character are subtracted from the number of all bytes of the characters of a text superscribed by the 1st character and stored in a saving memory 55. Based on the difference of said subtraction, the characters are read out of the end of the text stored in the memory 55 and then stored in an area following the area where the 2nd character is stored in the memory 54.
