Title: Magneto-optical recording medium
Inventor: KIKUCHI KAZUHIKO
IPC: G11B11/10
Filed: 1989-09-11
Abstract: PURPOSE:To reduce warpage generated after the process of forming grooves and to solve problems relating to conventional drawbacks such as fracture of a film, cracks, or bad environmental resistance by forming the substrate in a manner that its center part and outer circumferential part are made thicker than its groove area. CONSTITUTION:The magneto-optical recording medium is formed by successively depositing a base layer 5, magneto-optical recording layer 6 and protective layers 7,8 on a resin substrate 1. The center part and outer circumferential part of the film-forming side for forming grooves are made thicker than the groove area 3. By this method, the substrate has enough strength against warpage of itself to overcome the force such as stress in the film or residual strain due to thermal stress that might camber the substrate, and thus, warpage of the medium can be reduced. Moreover, residual strain so far regarded unavoidable can be prevented.

Title: Superconducting magnet
Inventor: HARADA AKIHIRO
IPC: A61B5/055
Filed: 1986-10-02
Abstract: PURPOSE:To prevent the application of high voltage to ground to a superconducting coil while obviating the creeping of currents through ground at the time of excitation or the time of demagnetization by mounting an inverse- parallel connection diode between an arbitrary point on the superconducting coil and a crysogenic vessel. CONSTITUTION:Mutually inverse-parallel by connected diodes 9 connect an arbitrary point on a superconducting coil 1 and a cryogenic vessel 3. Consequently, potential difference generated between a diode connecting section in the superconducting coil 1 and the cryogenic vessel 3 is held at forward turn-ON voltage or less at the time of the cryogenic temperature of the inverse-parallel connection diodes 9 at all times, thus generating no currents creeping between both grounds 7, 4 between a power supply 6 and the superconducting coil 1 when exciting or demagnetizing the superconducting coil 1. Likewise, discharge to ground by potential floating is not generated even at the time of stationary operation in the case where the power supply 6 and the superconducting coil 1 are detached by a connector 8.

Title: Bright correction circuit for liquid crystal display device
Inventor: SAISHO AKITO
IPC: G09G3/36
Filed: 1986-10-01
Abstract: PURPOSE:To prevent white collapse in a bright screen and black collapse in a dark screen by providing a smoothing circuit smoothing a picture signal and converting said signal into DC and a brightness setting circuit applying a control voltage to a brightness control terminal of a pedestal clamp circuit in response to the output of this smoothing circuit to correct the brightness automatically. CONSTITUTION:The emitter output of a 1st transistor (TR) Q1 is fed to the smoothing filter 9, where it is smoothed to DC. Since the smoothing filter includes an inverting circuit when the mean brightness level of the video signal is high, the output voltage is low, and when the mean brightness level is low, the output voltage is increased. Then the voltage of a moving contact of a user control variable resistor VR2 of the brightness setting circuit 10 is lower when the output of the smoothing filter 9 is low to lower the pedestal clamp level, and increases the voltage VB when the output of the smoothing filter 9 is higher. Thus, the white level is lowered at the time of bright screen and the black level is floated at the time of dark screen by correcting the brightness automatically.

Title: Method for reducing bacterial toxin mixed in high-molecule solution
Inventor: TOOMASU II KAAPURASU
IPC: C07K16/00
Filed: 1988-09-19
Abstract: PURPOSE: To obtain a macromolecule which is reduced in endotoxin contaminants by mixing a macromolecule polluted with endotoxin with a surfactant, bringing the aqueous mixture into contact with a non aqueous endotoxin adsorbent, separating the mixture into the solid and liquid phases and removing the surfactant from the liquid phase by dialysis. CONSTITUTION: A biologically useful macromolecule contaminated with endotoxins is mixed with a surfactant which can be dialyzed in an aqueous medium (for example, octyl-β-D-glucopyranoside, decanoyl N-methylglucamide) to prepare an aqueous mixture in which the surfactant does not reveal its net charge and its concentration is higher than its critical micelle concentration (the concentration of the macromolecule is 200μg-100mg/ml, particularly 1-50mg/ml). This mixture is brought into contact with a water-insoluble solid endotoxin adsorbent containing a solid matrix bonding to an endotoxin-adsorbing agent (for example, polymyxin B) and they are held for a certain time enough for the endotoxin to be adsorbed. Subsequently, the mixture is separated into the solid phase and the liquid phase and the surfactant is removed from the liquid phase by dialysis to prepare the objective macromolecule solution free from surfactant and reduced in endotoxin contamination.
