Abstract: PURPOSE: To enable detection with good accuracy, by analyzing the frequency within a given range among the signals produced at cutting work and comparing it with the preset reference.  
     CONSTITUTION: When the ratio F c /(F c ) 0 , between the frequency F c  showing the value of maximum output present between 0.1W10kHz among the oscillation signal produced from tool or machine tool under cutting work, and the initial frequency (F c ) 0  at cutting work, removes from 1, the performance of chip disposal is worse, and if this rate is ≤1/2 or ≥2, it is not preferable from the standpoint of safety of work, damage to tool, or quality of work. Accordingly, the detector 1 is fitted to the cutting tool or machine tool, and after the output is amplified 2, and the frequency of the maximum output between 0.1W10kHz is analyzed at the frequency analyzer 3 and it is fed to the comparator 4.

Title: Electrochromic light control plate
Inventor: MORI TAKAAKI
IPC: G02F1/17
Filed: 1988-04-30
Abstract: PURPOSE:To prevent the temp. rise of the light control plate itself and to prevent hat radiation by using laminated selective light transmittable films having two-layered structures consisting of a 1st thin film layer having electrical conductivity and a 2nd thin film layer to form at least either of a pair of transparent electrode films and disposing the 1st thin film layer side to face the other transparent electrode film. CONSTITUTION:Transmission of visible light is selectively permitted and the reflection of heat rays is selectively executed by the transparent electrode film 3A as the laminated selective light transmittable film of the two-layer structure consisting of the thin film layer 10 having heat ray reflectivity and transparent thin film layer 11 having a high refractive index characteristic. The thin film layer 12 constituting the transparent electrode film 3 acts as an electrode film. Coloration and decoloration of the color forming films 5, 6 are executed by impressing a voltage between the two transparent electrode films 3A and 3B. The heat rays are thereby reflected without hindering the transmission of the visible light and without absorbing the heat rays. The temp. rise of the control plate itself and the heat radiation are thus prevented.

Filed: 1993-05-10
Abstract: PURPOSE:To enable an accurate and high-sensitivity measurement even when an analyzation target is in a very small amount by measuring optical characteristics of a first reaction solution to obtain the concentration of a first component contained in a sample. CONSTITUTION:A sample, a first and a second reagent are dispensed into a specific reaction vessel 34 by a nozzle 43 to proceed reaction. A light flux 12 passes through the vessel 34 on a reaction turntable 2 during its rotation. At this time, photoabsorption measurement is made by a spectroscope 10 with the result that a signal value is outputted from the spectroscope 10. This signal value causes the signal of a necessary measurement wavelength to be selected by a multiplexer 60 to obtain a concentration of the first component. This concentration signal is latched into a controller C and compared with the reference value to decide whether or not the second component should be analyzed. Next, in the case where the second component is analyzed, a test solution containing educts is inhaled by the nozzle 43 and discharged into a sheath flow cell 47, where free particles in it are counted to determine a concentration of the second component.
