Title: Automatic analysis apparatus
Inventor: NAGARA SHINICHI
IPC: G01N1/00
Filed: 1990-06-06
Abstract: PURPOSE:To prevent the decrease in the evaporation of constant temp. water by providing a groove installed in the circumferential direction of a thermostatic chamber and a projecting part having a circumferential shape combined therewith on a reaction disk, thereby forming the spacing between the thermostatic chamber and the reaction disk into a labyrinth shape. CONSTITUTION:This apparatus is constituted to combine the grooves 2 provided on both sides of the thermostatic chamber 1 with the projecting parts 4 of the reaction disk 3 holding a reaction vessel 8. The steam generated from the constant temp. water 6 flows out of the spacing between the chamber 1 and the disk 3 but the outflow is impaired by the grooves 2 and the projecting parts 4 and, therefore, the decrease by the evaporation of the constant temp. water 6 is prevented. Condensed water 13 is the projecting parts 4 stagnate in the grooves 2 and return into the chamber 1 through a notches 12. The decrease by the evaporation of the constant temp. water 6 is prevented and a specified volume or above of the condensed water 13 accumulating in the groove 2 returns into the chamber 1 and, therefore, the need for exchanging the constant temp. water 6 during the analysis of a sample 7 is eliminated and the long-term operation is possible.

Abstract: PURPOSE:To detect the busy state of a telephone line for a call with simple circuit constitution by starting a no ringing incoming call detection circuit, supplying a voltage signal fed to the telephone line to the no ringing incoming call detection circuit thereby detecting the state of the telephone line. CONSTITUTION:A dialing line connection communication block 13 applies a voltage to a detection circuit 11 via a terminal call start diode 212 to check the voltage. The line voltage at that time is fed to a low voltage detection Zener diode 211 and a high voltage detection Zener diode 27 so as to identify whether or not the line voltage is within a voltage decided by both the Zener diodes, that is, within a range of nearly 36-60V. When the line voltage is within 36-60V, a no ringing communication block 14 gives a signal to the dialing line connection communication block 13 via a line state output line 12. As a result, the call line connection communication block 13 identifies it that the telephone line is not busy.

Title: Automatic measuring method of profile shape
Inventor: TAKAGI YUSUKE
IPC: G01B11/24
Filed: 1989-06-12
Abstract: PURPOSE:To solve the problem of the interference between an optical sensor and a body and the problem of the fact that an optical path cannot be formed and to make it possible to measure a complicated shape including recess parts by restricting the light projecting angle of the optical sensor at the value within a restricting range based on regions, and performing measurement. CONSTITUTION:An optical range sensor 3 utilizing a triangulation method is driven by a three-dimensional driving mechanism through a double-freedom-angle changing mechanism. The distance to the surface of a body is measured at an attitude by which the measuring surface of the body 2 forms a constant angle (in the vicinity of the vertical angle) with the optical axis. Thus, the shape of the body 2 is recognized. When the constant angle is made to be kept between the optical axis of the optical range sensor 3 and the surface of the body 2 in a region I and a region II where irregularities are large, the light axis is obstructed with the protruding surface, and the light does not reach the recessed surface. Therefore, in these regions, the optical range sensor 3 is restricted between Asmin and Asmax within the angle range wherein the reaching of the optical axis to the recessed surface is assured. Thus the measurement is performed.
