Title: Method for separating and culturing marine bivalve larval cell
Inventor: TAKEUCHI YASUHIRO
IPC: C12N5/073
Filed: 1993-05-24
Abstract: PURPOSE:To aseptically separate and culture a cell having adhesion, extension and proliferation abilities by partially digesting a marine bivalve larva generated by artificial insemination with a proteolytic enzyme, then culturing the resultant cell in a culture medium, proliferating the cell therein and forming a cell sheet. CONSTITUTION:A marine bivalve such as Mytulis edulis is washed and the shell is slightly opened to inoculate an adductor muscle with artificial seawater containing 0.1MKCl added thereto. The resultant marine bivalve is subsequently transferred to a beaker, placed at ambient temperature while carrying out the aeration to perform the spawning and discharge of eggs. The obtained eggs are subjected to the artificial insemination to artificially generate a larva. The marine bivalve is then partially digested with a proteolytic enzyme such as trypsin to separate a cell having adhesion, extension and proliferation abilities from the marine bivalve larva. The resultant cell is subjected to cell culture in a culture medium for the cell culture containing D-galactose, D-glucose or bovine fetal blood serum and proliferated to form a cell sheet. Thereby, the cell having the adhesion, extension and proliferation abilities of the marine bivalve larva is aseptically separated and cultured.

Title: Extension circuit of bidirectional signal line
Inventor: MURAKAMI ISAO
IPC: H04L5/14
Filed: 1983-07-05
Abstract: PURPOSE:To obtain a bidirectional signal line extension circuit which can be adapted flexibly to system configuration and reduces the production cost, by connecting the output of a driver circuit, which controls line extension, to one of two systems of bidirectional signal lines. CONSTITUTION:A DC level detecting circuit 4 sets an output F to logical ''1'' if a differential voltage between inputs A and B is higher than an input reference voltage signal REF, and the circuit 4 sets the output F to logical ''0'' if said differential voltage is lower than the input reference voltage signal REF. Consequently, a differential output driver 5 connected to an output G of an inverter 6 is set to the not enable state when differential output drivers 1 and 1' are in the enable state, and the driver 5 is set to the enable state when drivers 1 and 1' are in the not enable state. Thus, differential output drivers 1 and 1' of a transmission/reception control part and the differential output driver 5 of an extension circuit part connected to differential output drivers 1 and 1' are prevented from being set to the enable state simultaneously.

Title: Semiconductor switch
Inventor: MATSUYAMA MITSUO
IPC: H03K17/08
Filed: 1978-10-06
Abstract: PURPOSE:To enable to increase dv/dt rating and gate trigger sensitivity even at high temperature, by providing the semiconductor switch of PNPN constitution, resistor, electric short circuit means and capacitive circuit. CONSTITUTION:The resistor R2 is connected to the cathode K1 being one major terminal of the semiconductor switch (PNPN) 1, to build up a new cathode K2, and the resistor R1 being the short circuit means is connected between the cathode gate GK and K2, and the capacitor C1 is connected as the capacitive circuit between the anode gate GA and K1. When the forward transient voltage with steep rising is fed to the switch 1, the transient current flows to R1 through the second junction capacitor of the switch 1 and the potetial of GK is increased, but since the transient current flows to R2 via C1, the potential of GK is increased. That is, since any potential of GK and K1 are increased, then the voltage between GK and K1 is not great so much to increase dv/dt. Since this is almost independent on temperature, sufficiently greater dv/dt rating can be obtained.

Title: Electrostatic image developing device
Inventor: TOYONO TSUTOMU
IPC: G03G15/09
Filed: 1978-10-05
Abstract: PURPOSE: To freely control the densities of copying images and evenly maintain the same by disposing a coating magnetic pole in the developing device provided in opposition to the photosensitive drum and controlling the thickness of the toner on the developer supporting cylinder.  
     CONSTITUTION: Magnetic toner 12 deposits on a developer supporting cylinder 8. As the cylinder revolves, the toner moves in the arrow b direction and is evenly coated on the developer supporting cylinder by the coating magnetic pole N 1  opposing to a magnetic roller 10 which is rotating in the arrow c direction. The developer coated on the developer supporting cylinder in this way is conveyed along with the rotation of the developer supporting cylinder 8 and in the developing part it developes the latent images of an electrostatic image supporting means 1 without making contact with their non-image parts. Since the brush-form toner is coated in curtain form by the coating magnetic roller 10, the thickness of the toner is maintained extremely thin and evenly and therefore the densities of the copying images may be maintained even.
