Abstract: PROBLEM TO BE SOLVED: To set a foot switch function according to an operator's desire for smooth operation by allocating action signals of a device corresponding to an input signal of the foot switch, complying with an allocation program and by memorizing a combination of the action signals of the allocated device. SOLUTION: When functions of each switch of a foot switch section 6 are adjusted to an operator's desire, a memory card 4 memorizing desired contents of each operator in advance is inserted into a memory card reading/filling-out device 23. A key of a call screen shown on a display 22 is controlled to memorize an operator record content into a call memory 25. Action function data of the device corresponding to the input signal from the foot switch 6 are re-written thereby, thus the function of the foot switch 6 can quickly be set as the operator's desire and preparation for operation can efficiently be carried out.

Now, when Ag doped ZnS-CdS is used as the fluorescent film, wavelengths of emitting fluorescence can be controlled as the curve shown in the figure. When the density of CdS in the figure is 40%, the wavelength of emission becomes 0.55mum; when a ZnSe-Zn1-xCdxTe film is used as the photo diode, the wavelength can be made to coincide with the maximum range of wavelength 0.55mum, and the sensitivity becomes twice or more compared with the case when the blue light is used as it is. Besides, the same treatment is applied also to green and red.

IPC: B21B38/00
Filed: 1978-05-30
Abstract: PURPOSE: The titled detector which can directly, accurately detect the expansion, by detecting the expansion of the roll diameter depending on the axial expansion of the roll.  
     CONSTITUTION: The work roll 15 is driven by the driving motor 14, and the temperature of the work roll 15 rises up; then, if the backup roll 11 expands due to its temperature, the load of the load cell 10 on both sides increases through the spring 12, and its load signals F 1 , F 2 , are amplified 17 through the filter 16, and are summed 18 into the load signal F. This load signal F is added 20 to the memory value F 0  being stored in the memory circuit 19 when the draft position of the roll is calibrated; as a result, the increment ΔF is obtained. This increment ΔF is proportional to the axial expansion ΔL of the backup roll 11. Accordingly, from this result, the expansion ΔD of the diameter of the backup roll 11 is obtained (arithmetic circuit 22), and its signal is inputted into the sheet gauge controller.

Title: Simultaneous multi-item analysis
Inventor: YAMAMOTO HIDEKI
IPC: G01N35/10
Filed: 1985-03-28
Abstract: PURPOSE:To enable continuous distribution of the same reagent grouped in terms of analysis items, by performing a reagent distribution for the first time to permit the distribution of the first reagent regardless of reaction. CONSTITUTION:An analysis reagent is distritubed to each reaction tube in the order of analysis items shorter in the reaction time and subsequently, the sample of the corresponding analysis item is distributed into the reaction tube with the reagent distributed. The distribution of the sample is suspended temporarily before the start of the distribution of the sample of the analysis item shorter in the first reaction time than the preceding analysis item. After first reagents of a plurality of analysis items are distributed into a plurality of reaction tubes, successively, a batch of analysis operation - reagent distribution, sample distribution, reaction liquid suction and photometry - is started in repetition. So, the distribution of either the second or third reagent suffices within one cycle of repeating operations. Especially, only one operation at maximum of the reaction liquid sucking nozzle is enough within one cycle after the selection of the analysis item in the order shorter in the reaction time. The temporary suspension of the reagent distribution is done to avoid the duplication of the reagent distribution timings as more samples must be handled in the multi-item analysis.
