Title: Rate type automatic analyzing device
Inventor: NAKANO KIYOKAZU
IPC: G01N35/00
Filed: 1990-02-14
Abstract: PURPOSE:To measure rate reaction liquid without being affected by a sample blank value by measuring a rate reaction speed at plural timing points after a reagent is added to a sample, and finding rate reaction start extrapolation absorbance according to the measured speed. CONSTITUTION:A reaction disk 1 is driven to move a reaction container 2 which contains mixed liquid of the sample and reagent to a light absorbance station 5. At the station 5, the absorbance of the mixed liquid of the sample and reagent and rate reaction speed are measured at each of the measurement timing points. A microcomputer 6 calculates the rate reaction start extrapolation absorbance from the measured absorbance and rate reaction speed. The rate reaction start extrapolation absorbance which is thus found is compared with the absorbance values of reagent sample blank liquid which are found previously in order to decide whether or not the rate reaction is proper.

Title: Detecting method for minute movement of object
Inventor: IIJIMA GAROU
IPC: G01B11/00
Filed: 1980-03-20
Abstract: PURPOSE:To enable a simple and reliable detection of a minute movement, by a method wherein one of two photofibers, arranged on the same axial line, is secured on a minute movement detector, and a minute displacement is detected by means of a light amount passing through a surface positioned facing and opposite to the two photofibers. CONSTITUTION:A photofiber 3 is supported in a stable condition by means of a supporter 4 mounted on a foundation 5. Meanwhile, one end of a photofiber 8 is fastened on a loss meter 9, and the other, positioned facing and opposite to the fiber 3, is supported through the medium of a fixing onject 7 coupled to a minute movement detector 6. The fibers 3 and 8 are adjusted so that they are aligned on the same axial line, and this causes a minute displacement of an end surface 8a of the fiber 8, positioned facing and opposited to an end surface 3b of the fiber 3, according to the minute movement detected by the detector 6. As a result, a light amount of a light from a light source 1, propagating through the fiber 8 via the fiber 3, changes according to the displacement. Thus, a simple constitution permits the reliable detection of the minute movement through the working of the loss meter 9.

Title: Grinding method and grinding wheel
Inventor: TACHIKAKE YUUJI
IPC: B24B5/00
Filed: 1982-03-06
Abstract: PURPOSE:To achieve a highly efficient grinding in a centerless grinder by grinding instantaneously removing stress with multiaxial grooves of a grinding wheel while the variation cycle of a grinding force is held withing a small range of the compliance of a work. CONSTITUTION:A work W such as thin-tube-like one is supported on a blade B between a grinding wheel G and a dressing wheel R and is ground. This grinding wheel G is provided with grooves 2 of a depth D and a width T at a certain interval in the axial direction of the outer surface thereof. As the grinding wheel G rotates, a grinding pressure is applied thereon as cyclically varying depending on the goove 2. This frequency can be selected by the number of the grooves 2 and the revolutions of the grinding wheel as desired. Therefore, the number of the grooves is selected from the revolutions of the grinding wheel so that the frequency will be applied on the work to minimize the compliance. This enables the grinding pressure to be applied effective for the penetration of grits as if the work were greater in the rigidity of the work thereby ensuring a highly efficient grinding with a limited generation of heat.

Abstract: PURPOSE:To correct a smear at low cost by omitting the recording signal of a picture signal at the time of detecting the smear of a solid-state image pickup element to record and compensating the omitted recording signal at the time of a reproduction. CONSTITUTION:Since it is not understood that at which point the smear is actually generated in a recording system, after a generating point is detected by a flip flop(FF) 6, a timing processing is executed so as to have a signal extending through a next horizontal period by a FF7 and a video signal is delayed by 1H in a video processing part 4 to obtain a smear generating signal simultaneous with a smear generating line. According to the smear generating signal, a drop out is intentionally generated on the part of the horizontal line H10 of a recording FM signal. Then, when this recording signal is reproduced in a reproducing system, a drop out correcting circuit is operated to insert the video signal of a preceding line, for instance, to the omitted line due to the generation of the smear correct the smear. Thereby, the smear can be corrected at low cost.
