摘要:
A collector voltage of a power management semiconductor device is detected by a first comparator, and when the detected collector voltage exceeds a first reference voltage, the first comparator outputs a first detection signal. Furthermore, a gate voltage of the power management semiconductor device is detected by a second comparator, and when the detected gate voltage exceeds a second reference voltage, the second comparator outputs a second detection signal. The second reference voltage is a minimum gate voltage for feeding a rated power to the power management semiconductor device or over, and less than a line power voltage of a drive circuit of the power management semiconductor device. When both the first detection signal and second detection signal are being outputted, the gate voltage is reduced by a gate voltage reduction means so as to protect the power management semiconductor device from overcurrent and overvoltage.

An automatic analyzer which can remove air bubbles in a photometric light path within a reaction tank and can provide accurate measurement results with stability. The automatic analyzer comprises a reaction cell for mixing a sample and a reagent therein, a constant temperature bath for holding water in which the reaction cell is immersed, a suction pipe for sucking the water in the constant temperature bath, a return pipe for returning the water to the constant temperature bath, a pump disposed between the suction pipe and the return pipe and circulating the water, a heater for heating the water circulated in the constant temperature bath by the pump, and an air-bubble removing unit disposed between the suction pipe and the return pipe, having a water-tight structure to hold the constant temperature bath water therein, and removing air bubbles based on a difference in gravity between the water and the air bubbles.

An automatic analyzer which can perform automatic re-measurement, can release a sample for transfer to another unit, can easily perform pre-dilution of the sample, and is adaptable for a reduction in amount of the sample. The automatic analyzer comprises a reaction disk holding a plurality of reaction cells arranged in a row along the circumference of the reaction disk, and a sample dispensing mechanism for dispensing samples into the reaction cells on the reaction disk. The sample dispensing mechanism comprises a dispensing nozzle for dispensing the samples and a support mechanism for supporting the dispensing nozzle, and the support mechanism is disposed inside the circumference of the reaction disk along which the reaction cells are arranged in a row.

A film transfer tool which allows a transfer head to be disposed in any of the spaces between letters of normally used word processors for implementation of a smooth transfer operation of film and a method of making the same are disclosed. A feed reel 2 and a take-up reel 3 are adapted to interlock with each other and are disposed within a case 1. A film transfer tape a is fed out from the feed reel 2 to be moved along the surface of a paper S while being pressed thereagainst by a transfer head 4 protruding from the case 1, and is then taken up by the take-up reel 3 as a tape from which film has been transferred.

An object of the present invention is to provide a coating film transfer tool which is made smaller to provide superior portability and which can implement the replacement of a used up coating film transfer tape with fewer operations. According to the invention, there is provided a coating film transfer tool which can facilitate the replacement of coating film transfer tapes markedly by constructing such that when the main body is divided to be opened for supply of the refill for replacement the head automatically rotates to the tape replacement position, whereas when the main body is closed after the replacement with the refill has been completed the tape is automatically taken up to be wrapped around the distal end portion of the head whereby transfer work becomes possible.
摘要:
An automatic analysis system that, even if one module out of a plurality of analysis modules becomes analysis-incapable, allows the analysis to be continued without stopping the entire system. The automatic analysis system has a plurality of analysis modules 5, 6, 7, and 8, and a transferring line 3 for transferring specimens to these analysis modules. During the analysis operation by the entire system, each analysis module is controllable as a standby state, namely, as a single-body analysis module in a state of being independent and being cut off from the control of the entire system.
摘要:
A pressure reducing valve includes a first screw member on which a nut for adjusting the spring force of a pressure regulating spring travels, and a second screw member screwed into the first screw member and provided with a stopper for limiting the travel range of the nut at the tip. The second screw member can be displaced with respect to the first screw member along its length, so that the limiting range of the stopper against the travelling nut is adjustable.
摘要:
An annular train of reaction vessels is formed on an intermittently rotatable turntable. In order to measure test items requiring different analysis times, samples and necessary reagents are successively added to the reaction vessels. The analysis times for the test items assigned to the respective reaction vessels are stored in association with positions or numbers of the reaction vessels. Reactions for the test items requiring different analysis times proceed in parallel on the turntable. The reaction vessel whose required analysis time has expired is renewed by a vessel renew device such as a washing device and prepared for receiving the next sample. When a sample for a test item requiring a short analysis time is added to a second reaction vessel after a sample for a test item requiring a long analysis time has been added to a first reaction vessel, the second reaction vessel is renewed earlier than the first reaction vessel.
摘要:
According to an embodiment of the disclosure, the analyzer includes a reagent driving disk that accommodates a reagent configured for analysis and that transports the reagent to a desired position, and a fixed disk that has a reagent stand-by position in which to make a reagent container containing the reagent, temporarily stand by, and a magnetic particles stirring position for stirring magnetic particles. A portion of the reagent stand-by position is constituted by a loading system. A reagent container moving unit moves reagent containers containing the reagent, between the reagent driving unit and the fixed disk, according to analytical request status. Providing in a part of the fixed disk the loading system constructed so that reagent containers containing the reagent can be mounted therein during operation enables changing of reagent containers, irrespective of an operational status of the reagent driving disk, and the system to having cold-storage functionality.
