Abstract: PURPOSE:To adjust the feed speeds of plural yarns individually by providing turnback rolls comprising a roll formed by a portion having a designated outside diameter, in which normally a yarn runs, and a yarn running portion for adjusting the speed, which has a different outside diameter and is disposed adjacent to the above portion. CONSTITUTION:Three yarns 14a-14c from a processing device pass corresponding support pulleys 4a, 4b and moving pulley 6 to reach a draw-out roller 8 through a fixed guide 2. At this time, for example, if the yarn 14a is elongated excessively so that the moving pulley 6 is lowered by a weight 5, such lowering is detected by a position sensor 12 for detecting the lower limit position, and according to the detection signal, a moving conduction yarn guide 11' picks up the yarn 14a.

Abstract: PURPOSE:To control the overcurrent of an inverter by providing an induction motor (IM) overload protecting circuit added to a sensorless vector controller for detecting the torque overcurrent of the IM to feed back it to a speed command to prevent the overload current of the inverter. CONSTITUTION:An overload current of an IM input circuit generated by the overload operation of the IM is detected as the overcurrents of a magnetic flux current Iid' and torque current Iiq' of a circuit 1.

Title: Color recorder
Inventor: MURATA TAKAYUKI
IPC: B41J2/525
Filed: 1990-02-13
Abstract: PURPOSE:To record even if there is no main color ink by recording by replacing with a plurality of sub-color inks if the main color ink is wasted out. CONSTITUTION:A head 9A is a main recording means for recording a black color as a main color. If there is no main black ink at the time of starting recording, an operator switches a manual switch to generate a signal of gist of no possibility of recording with main ink, and to so switch a head drive signal as to superpose all heads 9B, 9C, 9D of sub recording means to record a black color. If a signal of no main ink is sensed on the way of recording, a recorder body generates a signal of gist of no possibility of recording with main ink in response to the sensed output to automatically switch the head drive signal, thereby recording the black color with heads 9B, 9C, 9D. If the head 9A of recording the main black color is not placed at the time of starting recording, the operator or the recorder itself switches the drive signal.

Abstract: PURPOSE:To adjust a delay time only by measurement at a reception side by synthesizing only a reception system on one side by performing phase inversion by 180 deg. out of two reception systems in a receiver of space diversity system, and adjusting synthetic output so as to be minimized. CONSTITUTION:When a signal from a transmission antenna 3 is received at reception antennas 4 and 5, the difference (electrical length difference) of path length L1 and L2 to the output terminals 1 and 2 of radio receivers 6 and 7 are adjusted as follows. Namely, a reception signal on one side is passed an infinite phase shifter 15 and an automatic gain control amplifier 13. Also, the signal on the other side, after being passed a delay line 11 equivalent to the absolute delay quantity of the phase shifter 15, is passed an automatic gain control amplifier 12 whose absolute delay quantity and output voltage are equal to that of the amplifier 13. Next, they are controlled by the phase shifter 15 and a phase detector 14, and their signal phases at a synthesizer 9 are set so as to be set at 180 deg., respectively. Following that, the output of the synthesizer 9 is detected by a measuring instrument 10, and the electrical length L1 and L2 are adjusted so as to be minimized, thereby, a delay time difference between reception paths can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To enable at least one wavelength of lights to pass through one filter specific times or more by providing a reflection surface which is positioned so as to reflect an input light emitted toward the input end face of a first refractive index distibution type lens and which at least performs a reflection partially. SOLUTION: First and second refractive index distribution type lenses 10a, 10b share a common optical axis, however, a third refractive index distribution type lens 10c is constituted by being shifted from the optical axis of the two lenses. A reflection surface 42 transmits 5 percents of a light to be made incident on the surface. Then, lights having wavelengths λ1, λ2 are emitted toward the input terminal being on one end of the lens 10a. A WDM filter 30 reflects the light having the wavelength λ1 and transmits the light having wavelength λ2 shown by a double arrow. The light propagates to the light 10b, 10c and the major part of the light is reflected backward in a different path by the reflection surface 42 to be outputted from the end face of the lens 10a at a port 7.  That is, a signal having the wavelength λ2 at the port 7 passes through the WDM filter 30 twice.
