Title: Divided-type optical fiber tape core
Inventor: KUROSAWA YUTAKA
IPC: G02B6/44
Filed: 1990-11-29
Abstract: PURPOSE:To make the thickness of a tape core approximately the same as the outer diameter of an optical fiber element and allow the tape core to be divided by adding mold releasing material between optical fiber elements to be divided, and forming a covering in such a way that the thickness of the tape is the same as the outer diameter of the optical fiber element or the element outer diameter plus the specific value or less. CONSTITUTION:Eight-core colored elements 11 are arranged closely in parallel, and mold releasing material 12 is stuck between the fourth element 11d and the fifth element 11e among the respective elements. All the elements 11a-11h are then covered into tape shape with a covering 13 made of ultraviolet-ray hardened resin or the like. The covering 13 is so formed that the tape thickness is the same as the outer diameter of the optical fiber element 11 or the fiber element wire outer diameter plus 20mum or less. The mold releasing material 12 is made of such material as to make separating performance between the covering 13 and the element 11 better between the fourth and fifth elements 11d, 11e than between other element parts without bonding the fourth and fifth elements 11d, 11e to each other so as to generate the division of a tape core 10 at this part. The thickness of the tape core 10 is thereby made approximately the same as the outer diameter of the optical fiber element 11, and the tape core 10 can be also divided.

Abstract: PROBLEM TO BE SOLVED: To provide a low-priced charging/discharging detector which is capable of detecting charging current and discharging current of different polarity from each other with a simple structure, by amplifying level shift voltage which level shift means outputs and outputting detected voltage. SOLUTION: A level shift means 5 is constituted of a level shift circuit and so on, and level-shifts the detected voltage V1 corresponding to charging current and discharging current of different polarity from each other detected by a detection resistor RD by a prescribed value and supplies level shift voltage VLS to an amplifying means 6. The amplifying means 6 is constituted of a differential amplifier and amplifies the level shift voltage VLS outputted by the level shift means 5 to output the detection resistor RD. It is thus possible to set the detected voltage VD corresponding to charging current IC and discharging current ID outputted by the amplifying means 6 to an arbitrary voltage range.  It is also possible to convert the detection of charging current and discharging current of different polarity from each other into a voltage level range of single polarity suitable for battery driving, thus providing a low-priced charging/discharging current detector whose structure is simple.

Title: Speed controller of motor
Inventor: YOSHIOKA KANEHARU
IPC: H02P7/29
Filed: 1988-12-28
Abstract: PURPOSE:To control a motor at a wide constant speed without dropping control performance by keeping the gain of a speed loop constant. CONSTITUTION:The reference period of reference period setting means 2 and the gain of a DF(digital filter) 3 are set by degeneration rate setting means 9. Pulse periods of previous time before previous time and previous time are Tn-1, the pulse period of previous time and this time is Tn, the speed calculated from them is upsilonn-1, upsilonn, and variation in the period is AT. Then, the variation upsilonof the speed becomes as an equation. That is, since the speed variation is approximately proportional to the value obtained by dividing the period variation by the square of the reference period, it is necessary to multiply the period error by the square of the reference period so as to control the speed with the period error. Accordingly, a proportional integration gain may be so varied as to be proportional to the square of the reference period in response to the setting of the degeneration rate. Since the gain alteration of the DF3 may be conducted only at the time of alteration of the degeneration rate, it is irrespective during the operation of the motor.
