Title: Magnetic recording medium
Inventor: YAMAGUCHI ATSUTAKA
IPC: C09D133/08
Filed: 1983-03-08
Abstract: PURPOSE:To obtain a magnetic recording medium having a high modulus of elasticity, superior mechanical strength and durability by preparing a magnetic coating material with a liq. acrylic oligomer and polyester resin as binder components and a small amount of an org. solvent. CONSTITUTION:A magnetic layer contg. dipentaerythritol hexaacrylate, the mono to penta ester of dipentaerythritol with acrylic acid, polyester resin and magnetic powder is formed. As acrylic oligomer prepd. by mixing the hexaacrylate with the ester is liq. and has many double-bond groups per one molecule, so a magnetic coating material can be prepd. with a small amount of a solvent, and high cross-linking density is attained by polymn. and curing under radiation. As a result, the dispersibility and fillability of the magnetic powder can be improved, and the electromagnetic transducing characteristics can be improved. The polyester resin has a great affinity for the magnetic powder and disperses well the powder. Accordingly, the dispersibility of the magnetic powder is further improved by adding the polyester resin, and the electromagnetic transducing characteristics are improved.

Title: Pulse laser oscillation device
Inventor: YASUOKA KOICHI
IPC: H01S3/036
Filed: 1988-02-23
Abstract: PURPOSE:To obtain a highly efficient and large-output pulse laser oscillation device by connecting a main electrode to an external peaking capacitor through a disc-like current feedback conductor wherein the surface is insulation-treated and by reducing current path inductance of main discharge current. CONSTITUTION:When a high-voltage high-speed pulse voltage is applied between a high-voltage terminal 7 and a disc-like current return conductor 8 wherein the surface is insulation-treated, spark discharge is ignited between the terminal 7 and a preliminary ionization electrode 6 and a peaking capacitor 9 is charged by flowing current. If voltage of this capacitor 9 increases and strength in electric field at the main discharge space exceeds gas discharge breakdown voltage, discharge breakdown occurs and a high-speed current flows into discharge space in the order of a capacitor 9, a glow discharge 10, a main electrode 3, a disk-like current return conductor 8, and the capacitor 9. Thus, since no discharge breakdown voltage occurs from a main electrode 2 toward a conductor 8 even if th rectifying grid-type current return rout is brought closer to the main electrodes 2 and 3, no discharge breakdown voltage is produced from the main electrode 2 toward the conductor 8, the conductor 8 can be placed closer to the main electrodes 2 and 3. Thus, inductance at the main discharge flow path does not increase and start-up rate of main discharge current is rapid.
