Title: Split type optical fiber tape
Inventor: ARAKI SHINJI
IPC: G02B6/44
Filed: 1988-03-31
Abstract: PURPOSE:To prevent an increase of a transmission loss by using an ultraviolet curing resin having a Young's modulus of >=5kg/mm<2> at an actual use highest temperature of a split type optical fiber tape, for a solid forming material. CONSTITUTION:A multicore fiber 5 in which plural optical fibers 1 have been covered in a lump with an ultraviolet curing resin 6 is unified by using the ultraviolet curing resin 6 whose Young's modulus at an actual use highest temperature of this optical fiber tape is >=5kg/mm<2>. In this case, the actual use highest temperature of the split type optical fiber tape is the highest value of a temperature which is predicted under the environment for using this optical fiber tape, and usually about 60 deg.C. Accordingly, even if a temperature of the use environment rises, a correct tape shape is held stably, and no irregular bend is generated in the optical fiber 1. In such a way, it does not occur that a transmission loss increases in the course of use, and the split type optical fiber tape whose transmission loss characteristic is satisfactory can be obtained.

Title: Pulse-width modulating amplifier
Inventor: ADACHI HIROO
IPC: H03F3/217
Filed: 1979-06-25
Abstract: PURPOSE:To realize a pulse-width modulating amplifier of simple constitution which can generate high electric output power, by exercising alternate ON-OFF control over output switching elements synchronizing with a pulse-width modulated signal. CONSTITUTION:When pulse-width modulated PWM signal (a) is low in level, voltage +Vcc is applied only across capacitor C1 since voltage-applying switching element 9 turns ON, so that -Vcc will be developed at push-pull output terminal (d) via output switching element 5. Next, when PWM signal (a) is held at a high level, voltage-applying switching element 8 turns on to apply voltage +Vcc only across capacitor C2, and consequently terminal (b) is held at a voltage of +2Vcc to output +2Vcc to push-pull output terminal (d) via switching element 4. Therefore, a composite wave at output terminal (d) is a signal of 3Vcc in amplitude that synchronizes completely with PWM signal (a).

Abstract: PURPOSE:To obtain a stirred mixing tank capable of forming high-dense flocs in a short time with a high stirring efficiency by partitioning a vertical inner cylindrical tank in a staggered manner by vertical tubes and baffle plates in such a way as to form zigzagged flow paths. CONSTITUTION:The inside of a vertical cylindrical tank 1 whose lower part is provided with a liquid chamber 5 into which a liquid to be treated and a liquid to be added are introduced is partitioned by vertical tubes 7 whose lower end is opened toward the upper plate of the liquid chamber 5 and the upper end is opened toward the space inside the tank 1 and baffle plates 8 in staggered manner in such a way as to form zigzagged flow paths in the vertical direction.

Filed: 1993-04-07
Abstract: PURPOSE:To prevent the material to be machined from being damaged, and to execute the machining with high precision by absorbing or scattering the excimer laser beam transmitted through the holding member. CONSTITUTION:The reflection of a holding member 21 of the excimer laser beam passing through a film 12 at the holding surface 21a is prevented by a reflection preventing film, and the energy density of the excimer laser beam is reduced by diffusing the transmitting excimer laser beam between the holding surface 21a and the rear surface 21b to be attenuated to the energy level below the threshold.
