Title: Optical fiber cable and its production
Inventor: BROWN ROBERT J
IPC: G02B6/44
Filed: 1999-10-18
Abstract: PROBLEM TO BE SOLVED: To obtain a central core optical fiber cable of a low cabling loss having a stack of longitudinally twisted ribbons. SOLUTION: Plural optical fiber ribbons are stacked in an array form and are arranged within a tube existing at the center of the cable. A lubricating material is applied between the adjacent ribbons of the stack 200 in order to integrally holds the plural ribbons and to make the slip movement between the ribbons easy. The stack 200 of the ribbons is twisted along the longitudinal direction of the cable. The lubricant is alpha olefin oil. The stack 200 of the ribbons is twisted to one direction during a first prescribed distance and is then twisted in a reverse direction during a second prescribed distance. These distances are nearly equal to each other. An electrostatically charged powder is otherwise used as the lubricant.

Title: Hydraulic winch
Inventor: NISHIOKA YOSHITAKA
IPC: B66D1/08
Filed: 1992-11-05
Abstract: PURPOSE:To shorten the length of a hydraulic winch in the rotating shaft axial direction, and thereby make the hydraulic winch small in size by letting at least a part of a hydraulic motor break intrude into the inside of a winch drum, and thereby disposing a valve in a place above the winch drum. CONSTITUTION:A part of a hydraulic motor 3 is housed in the inside of a winch drum 2, and a valve unit 7 is installed on the upper surface of a frame 1, dimension in the rotating shaft axial direction is thereby made extremely small, so that the great number of hydraulic winches can be arranged in parallel in a limited space over a stage. Moreover, since the rotation of the winch drum 2 is devised to be transmitted to a rotary encoder 6 via gears 4 and 5, the rotating speed of the winch drum 2 can thereby be accurately detected. Furthermore, a servo amplifier is also provided over the frame 1, distance required for transmitting the detected signal is therefore shortened, there is less chance for noise to be mixed in, so that control high in reliability can thereby be executed.

Filed: 1988-11-25
Abstract: PURPOSE:To reduce the noise and improve in balancing the passage of air through heat exchanges by making the air discharged from the outlet of a centrifugal multiblade fan impinge against the top of the casing and, after thus dispersing the air, by making it pass through the heat exchangers. CONSTITUTION:During the operation, indoor air is taken into a casing 1 through an inlet 7 by a fan 11. The air is drawn into the fan 11 through suction openings at both sides of the fan casing 16 and discharged thought an opening 16b at the top end. This opening 16b faces the top surface 1a of the casing 1; the air discharged from the opening 16b impinges against the top surface 1a of the casing 1, flows into heat exchangers 12 in separate streams, and, after undergoing heat exchange therein, flows out into an indoor space through outlets 9 in a ceiling panel 5. By placing a second louver 17 at the center the air discharged can be evenly dispersed right and left. The air discharged from the opening 16b in the fan casing 16 does not impinge directly upon the heat exchangers 12 but first strikes the top surface 1a of the casing 1 and then flows to the heat exchangers 12.

IPC: G11C11/409
Filed: 1990-10-31
Abstract: PURPOSE:To arbitrarily set an output bit constitution and to use the output bit constitution as a plurality of pieces of memory devices by constituting an output buffer section of a plurality of output buffers and setting the output bit constitution by individually controlling the output buffers. CONSTITUTION:An output buffer section is constituted of a plurality of output buffers 14a and 14b and a controlling means 16 individually controls the output buffers 14a and 14b. Accordingly, when, for example, all of the output buffers 14a and 14b are set to active states, the output bit constitution of the output buffer section becomes the maximum bit constitution decided at the time of design and, when only one output buffer 14a is set to an active state, the output constitution of the output buffer section becomes the bit count of the buffer 14a. In addition, the plurality of the buffers 14a and 14b can be selectively set to active states. Therefore, not only the output bit constitution can be changed, but also one piece of a large-capacity memory device can be used in the same way as a plurality of memory devices.

Abstract: PURPOSE:To enable stable detection of impact with a shortening of sensing time by generating a voltage with a level thereof corresponding to a pressing force of an inertial body corresponding to an impact force from a piezo-electric element to be outputted via an impedance converter. CONSTITUTION:An impact sensor 100 is carried on a vehicle in such a manner that a housing 10 is directed at the front side of the vehicle. Then, when acceleration is applied to the sensor 100 in a direction of stopping the vehicle, an inertial body 22 presses a piezo-electric element 20 and a generation voltage of the element 20 corresponding to a pressing force is transmitted to a circuit assembly 44 through an electrode 18, a flange 14 and a screw 38 and then to the circuit 44 through the inertial body 22 doubling an electrode, a bolt 24 and a lead terminal 32. The circuit 44 converts the generation voltage of the element 20 to an impedance and a signal corresponding to a voltage is outputted to an inflator operation circuit from a connection terminal. Here, the circuit 44 works to reduce an impedance of an output to be taken out between an output terminal 71 and a feeder terminal 74 of a battery in a combination of a negative feedback operation amplifier 70 and an output resistance R3 thereby enabling stable detection of impact.
