IPC: G01N35/00
Filed: 1983-10-22
Abstract: PURPOSE:To discover easily abnormal data of an inspector and to improve the measuring accuracy in processing measuring data of an automatic analyzing device for blood which performs biochemical or immunological analysis by storing only the specific smaller number of measuring data into a memory. CONSTITUTION:Measuring light l is irradiated to a serum specimen 1 and is converted to voltage which is inputted to a data processor A. The processor converts the measuring data to a digital signal and records the signal into a memory circuit 6. The signal is displayed on a monitor device 11 via a data decision circuit 8 and is recorded in a recorder 12. Reference data X is in inputted to a computer 7 and is compared with measuring data in the circuit 8. When the measuring data Y1 is in a permissible range of the reference data X, the data is excluded from the circuit 6 and only the data Y2 which is out of the permissible range of the data X is stored in the circuit 6. The inspector is therefore capable of finding easily only a small number of the abnormal data stored in the circuit 6. The fault of the machine is thus discovered and the measuring accuracy is improved. The size of the memory circuit is reduced as well.

IPC: G03G15/05
Filed: 1992-07-24
Abstract: PURPOSE:To make the acceleration of charge injection compatible with the stable formation of a toner visible image and to obtain excellent transfer characteristic by using two-component developer, electrostatically charging a photosensitive body through conductive magnetic carrier and forming the visible image by the use of insulating magnetic toner. CONSTITUTION:The two-component developer 6 constituted of the conductive magnetic carrier 8 and the insulating magnetic toner 7 is used, and the charge injection is performed to the surface of the photosensitive body 100 from a developing sleeve 200 through the carrier 8.

It is desirable that the rate of the insulating toner to the developer 6 is about 1-5%, which is considerably small in comparison with the conventional two- component developer. Thus, electric resistance becomes low as entire developer and the charge injection to the surface of the photosensitive body through the carrier 8 becomes excellent.
Patent JP-H0519009-A (JP)
Title: Esd tester
Inventor: FURUYA TAKAHIRO
IPC: G01R31/14
Filed: 1991-07-11
Abstract: PURPOSE:To obtain an ESD tester which does not require use of a high voltage power source and is appropriate for mass production. CONSTITUTION:Relays RL1 to RLm connect capacitors C1 to Cs in parallel via a resistor R1 between an input terminal 1 and a ground terminal 2. Voltage is applied between the input terminal 1 and the ground terminal 2 to charge the voltage to the capacitors C1 to Cs. The relays RL1 to RLm are switched so that the capacitors C1 to Cs are connected in series between the ground terminal 2 and an output terminal 3. Thus voltage with voltage charged to the capacitors C1 to Cs added is discharged to the output terminal 3. Even if low voltage is applied to the input terminal 1, high voltage can be discharged to the output terminal 3. Therefore use of a high voltage power source is not necessary, reducing a weight of an apparatus. In addition, selection of the number of capacitors C1 to Cs allows different kinds of voltage to be output to the output terminal 3, resulting in flexibility and appropriateness for mass production.
