The monomers M1, M2 and M3 are mixed, and a prescribed amt. of a photopolymn. initiator [for example, benzoyl peroxide (BPO), benzoin methyl ether, etc.] is dissolved therein. The mixture is filled in a glass tube which has a prescribed bore (for example, about 2.9mm.) and is closed at one end, then the mixture is photopolymerized. A tubular UV lamp is provided at the center of the device, and cylindrical light shielding plates are attached in the upper and lower parts of the lamp so that the mixture in the glass tube 4 is irradiated only by the UV light released from the central part of the tube.

Abstract: PURPOSE:To obtain the plastic tank provided with high strength baffle plate in a simple producing process by a method in which the tank stock with dividing walls is blow molded, using a parison, and drill working is applied onto the dividing walls. CONSTITUTION:The tank wall extruding mouth 1a and the dividing wall extruding mouth 1b formed on an extruding die 1 extrude respectively the portions becoming a tank wall 4a and dividing walls 4b of a parison. At blow molding, first, as the parison with dividing walls 4b is caused to be molded, the tank stock with the tank dividing walls 6b is obtained by only carrying out normal blow molding, using this parison. By only forming through holes 6c in these dividing walls 6b, these holes provide the action of baffle plates, thereby obtaining the fuel tank 8 provided with baffle plates in very simple manufacturing process. Moreover because the peripheries of the dividing walls 6b are made integrally with the tank wall 6a, its strength is remarkably improved.

Title: Loop filter for pll frequency synthesizer
Inventor: KIMURA SHIGERU
IPC: H03L7/107
Filed: 1980-02-05
Abstract: PURPOSE:To reduce the frequency drawing time, by connecting each of the bases of the npn and pnp transistors to the input of a filter and each of the emitters to the output of the filter, respectively, and furthermore connecting a power source between the collectors. CONSTITUTION:The transistor 6 is turned on when the input voltage of the loop filter 8 becomes higher than the output voltage +VBE. The load capacity of the filter 8 is changed quickly by the collector current of the transistor 6. As a result, the input voltage becomes identical quickly to the output voltage. On the contrary, when the input voltage becomes lower than the output voltage -VBE, the transistor 7 is turned on. The load capacity of the filter 8 is discharged quickly by the collector current of the transistor 7. As a result, the input voltage becomes equal quickly to the output voltage. Then the input voltage becomes equal to the output voltage for the filter 8 when the PLL frequency synthesizer is locked to a certain frequency.
