Title: Liquid dispensing device
Inventor: MIYAMOTO HIROMIZU
IPC: G01N33/50
Filed: 1979-09-21
Abstract: PURPOSE:To secure an automatic and accurate dispensation for the liquid such as the blood serum or the like which received a layer separation by a centrifugal machine, by providing a tube having the open tip, a nozzle to suck and exhaust the liquid to be dispensed, and others. CONSTITUTION:The nozzle 1 which sucks and exhausts the liquid to be dispensed and has the open tip is formed with the insulating tube such as the Teflon or the like. This nozzle 1 is located so that its tip may be positioned at the bottom part of the blood serum layer 3 within the blood collecting tube 2 which is properly given a centrifugation via the driving unit or the optical detecting means. And the vaccum pump 6 is linked properly with the nozzle 1 via the 2-way electromagnetic valve V1 plus the 3-way electromagnetic valves V2 and V3 each. Thus the blood serum in the tube 2 is sucked up via the nozzle 1. In this case, the electrodes 10a, 10b, 11a and 11b detect electrically the change of the electric resistance or the like in case the blood serum exists among those electrodes and in case no blood serum exists respectively. Thus an automatic control is given to the drive of the pump 6.

Title: Check system for transmission data by multi-cpu
Inventor: SAKASHITA KATSUHIDE
IPC: H04L1/16
Filed: 1984-06-15
Abstract: PURPOSE:To check securely the transmission state of data including its event and contents by sending a command as a command echo to a master CPU together with an ACK code when the command is normal and executing the command. CONSTITUTION:When the command is transmitted from the master CPU to a slave CPU2, the slave CPU2 checks whether or not there is the fetched command of ID=1 in a table and then checks on the number of commands if so. When the number of commands is coincident, ACK data consisting of a command echo and an ACK code is transmitted to the master CPU1. Further, when there is no command of ID=1 in the table or when the number of commands is dissident, NACK data consisting of the command echo and an NACK code is sent to the master CPU1. Therefore, the master CPU1 decides on the state of transmitted data on the basis of not only the ACK and NACK codes, but also the command echo.

Title: Method of etching aluminum foil for electrolytic capacitor
Inventor: KOIKE ATSUSHI
IPC: C25F3/04
Filed: 1989-05-17
Abstract: PURPOSE:To make high the density of pits by a method wherein etchings are respectively performed chemically in an aqueous solution containing fluorine ions, electrically in an aqueous solution containing sulfuric acid ions and electrically or chemically in an aqueous solution containing nitric acid ions. CONSTITUTION:A natural oxide film generated on the surface of an Al foil is uniformly dissolved by an etching action using fluorine ions. Then, by making the Al foil decompose anodically, a film is formed of sulfuric acid ions on the surface of the foil and the dissolution on the foil surface is inhibited. At the same time as this, as pits are formed of chlorine ions which are added, the surface of the foil is never dissolved and the density of the pits becomes very high. In this process, the density of the pits is high, but the pits are fine. Successively, by performing an electrical or chemical etching on these pits in an aqueous solution containing nitric acid ions, Al is dissolved along the inner walls of the pits and the diameters of the pits become wide. Thereby, the pits are uniformly dispersed and the density of the pits can be made high without decreasing the enlargement rate of the surface area of the foil.
