Title: Control device of electromagnetic dc clutch
Inventor: TAKAHASHI YOSHINORI
IPC: H02P15/00
Filed: 1984-03-22
Abstract: PURPOSE:To enhance a transmitting function of power, by providing a voltage supply means, which supplies voltage higher than a level of the rated voltage to a clutch when its operation is started while supplies the rated voltage to the clutch when it is in steady operation, in the case of a control device of the electromagnetic clutch. CONSTITUTION:Capacitors C1, C2, being charged with voltage higher than the rated voltage of a clutch CMg from a voltage doubler control circuit 12 when a clutch operating switch SW is opened, are discharged applying larger voltage to the clutch CMg when the clutch operating switch SW is closed. As a result, power can be sufficiently transmitted by increasing attractive force.

Title: Breakage detecting method of tape or sheet
Inventor: TSUMURA AKIO
IPC: B65H26/02
Filed: 1984-03-21
Abstract: PURPOSE:To enable generation of any breakage in all kinds of tape or sheet to be detected by interlocking a mechanism of detecting pulse generation with a taking-up device, thus detecting generation of any breakage through changes in pulses generated at the time of taking-up of tape or sheet. CONSTITUTION:Tape or sheet T processed within a specific range of speed is taken-up by rotation of a bobbin 5, thereby giving some preset tension to the tape or sheet T by starting rotation of a torque motor 1. Because of this tension on the tape or sheet T at the time of taking-up, a winding shaft 2 rotates at a taking-up speed and a pulse detector 13 detects number of pulses generated during taking-up of the tape or sheet T. If any breakage is caused in the tape or sheet T under these conditions, any load on the torque motor 1 by taking-up tension of the tape or sheet T is eliminated, and therefore, the winding shaft 2 rotates at a higher speed than taking-up one and the number of pulses detected by the pulse detector 13 increases to a great extent than those during taking- up, thus enabling generation of any breakage of the tape or sheet T to be detected through this change in number of pulses.

Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain in high productivity a brush of such a type that bristles and the handle are integrally formed and in which transplanting strength of the bristles is high, no burr occurs, and the bristless stand good. SOLUTION: A bundle 1 of bristles is inserted into each of a plurality of bristles bundle insertion holes 4 provided in a forming mold 5. Ends 11 of the bristle bundles projecting from the forming mold 5 are heated and melted by a heating means of a heater 7, thus forming an integrally fused member 2 in which the neighboring bristles bundles 1 are connected. A cavity 8 having therein the fused member 2 is formed in a handle forming mold 6 and a forming material is injected into the cavity 8 and is welded as a handle head part.  After that, when detaching the handle from the forming mold 5, the bundles 1 of bristles are pulled for a predetermined amount from the bristles bundle inserting holes 4 while keeping the continuation of the bundle 1 of bristles by an extruding pin (not shown) or other extruding means and are cut by cutting means such as a cutter 9 and a fixed part 91 at a predetermined length position. Thus, the brushes can be effectively and continuously produced. By embedding the fused member 2 in the forming material in the cavity, the high-quality brush in which no burr occurs in the bristles transplanted part and the bundles of bristles and the transplanting strength is high can be realized.

Abstract: PURPOSE: To make the echo control system adapted for service superposition and gradual fluctuation of the SN ratio, by estimating the line noise and the identification error of the echo path model successively and by using the estimation quantity  to change the estimated step gain of the model successively.  
     CONSTITUTION: In the adaptive echo canceller where the receiving signal and the echo signal are used to cancel the echo while estimating the transmission characteristic of the echo bus, receiving input signal x j  from terminal 2 is sent to terminal 4 and register RG6. A part of signal x j  is returned to transmission-side input terminal 5 as echo y j . The receiving signal from RG6 is sent to convolutional operator 7, and this signal and the estimate value of the impulse response in RG8 are operated, and the operation result is sent to subtractor 10 as spurious echo signal Y j . Residual echo signal e j  which is the difference signal between signals y j  and Y j  is generated in subtractor 10 and is sent to transmission-side output terminal 3 and corrector 9. Corrector 9 uses signal x j , step gain coefficient α j  sent from coefficient determining circuit 11, and signal e j  to generate a new estimate value and sends this estimate value to RG8. In this case, circuit 11 uses estimate noise n j  from line noise estimating circuit 12 and the identification error from identification error estimating circuit 13 to determine coefficient α j .

Title: Hot water supplier
IPC: F23D14/02
Filed: 1992-03-16
Abstract: PURPOSE:To enable decrease of exhaustion of NOx without any disadvantage such as increase of exhaustion of CO by A method wherein a water supply passage is passed through an upper half of a space surrounded by a wall member and apart from the wall member. CONSTITUTION:In an upper half of a space surrounded by a wall member 11, where combustion reaction is proceeding, flame temperature rises up relatively high. On the other hand, in a lower half of the space, where the combustion reaction is not proceeding, the flame temperature is relatively low. Accordingly, by passing a water supply passage 20 through the upper half of the space, the flame in the low temperature part is not robbed of heat, while the flame temperature in the high temperature part is lowered, whereby exhaustion of NOx can be reduced. Also, as the flame is formed along the wall member 11, if the water supply passage 20 is placed apart from the wall member 11, formation of the flame is not be prevented.
