Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a warp tension control method intended to compensate the malcontrol due to the response delay of the tension control in the change- over between a pile weave pattern and another weave pattern. SOLUTION: In this method, when a pile weave pattern is to be switched to another weave pattern, a loom control computer Co transmits a reverse revolution demand signal to a let-off control unit C2, which, in turn, calculates reverse revolutions based on the reverse revolution demand signal and the tension detection information given by a tension detector 221 as well as works so as to make a sending-out motor Mp perform a forced reverse revolution of the above-calculated value.  When another weave pattern is to be switched to a pile weave pattern, the loom control computer Co transmits a normal revolution demand signal to the let-off control unit C2, which, in turn, calculates normal revolutions based on the normal revolution demand signal and the tension detection information given by the tension detector 221 as well as works so as to make the sending-out motor Mp perform a forced normal revolution of the above-calculated value.

Inventor: DOBASHI NOBORU
IPC: H02J7/02
Filed: 1992-05-14
Abstract: PURPOSE:To realize the refreshing function with simple composition and to execute a refreshing processing automatically which removes the memory effect of a battery, by lowering charging voltage when refreshing is needed, discharg ing the battery completely by supplying power to a load from the battery, raising the charging voltage and charging the battery fully after that, and performing repeatedly these refreshing procedures. CONSTITUTION:A charge and discharge monitoring processing part 41 counts the remaining quantity of a battery 1, and measures the number of times of discharge from full charging which does not lower the quantity below a specified remaining quantity. When the measured value exceeds a specified number of times, it is judged that refreshing is needed. The voltage supplied to the battery 1 is lowered by controlling an adaptor 9, etc. A refreshing processing part 42 starts discharging and performs discharging completely by making the battery 1 supply power to a load. After that, the voltage of the adapter 9, etc., is raised and full charging is performed. These charging and discharging procedures are repeated specified times, and the memory effect is removed.

     CONSTITUTION: This sensitizer is obtd. by mixing Pd and Sn (II) in 1:30W1:60 molar ratio in an acidic aqueous soln. and heating them. At this time, by raising the temp. to about 80W120°C after the mixing, both the sensitizing activity and stability are enhanced furthermore. For example, about 730ml pure water, about 200ml concd. hydrochloric acid, about 3g PdCl 2 , about 210g SnCl 2  and about 0.5g surfactant are heated, boiled for about 1W2hr, and cooled slowly. The resulting soln. is taken out by about 50ml and added to about 1l hydrochloric acid with  about 10% concn. to prepare a sensitizing soln. No Pd is settled in the soln., and  superior stability is shown.

Title: Method for measuring gas concentration
Inventor: ASADA AKIYOSHI
IPC: G01N27/41
Filed: 1987-05-20
Abstract: PURPOSE:To effectively improve responsiveness by changing a monitor voltage according to the output current of a sensor corresponding to a specific gas concn. and adjusting the difference in the monitor voltage between the case in which the specific gas concn. is 21% and the case in which said concn. is 0% to a prescribed voltage of 0.2-1.0V. CONSTITUTION:The sensor output current Is detected by a sensor current detecting circuit 7 corresponds to the concn. of the ambient gaseous oxygen. This current Is is fed back to a monitor voltage setting circuit 6. The circuit 6 changes the monitor voltage Vs in accordance with the fed back current Is to increase the voltage Vs when the current Is increases with an increase in the oxygen concn. and to conversely decrease the voltage Vs when the current Is decreases with a decrease in the oxygen concn. The circuit 6 sets the voltage Vs (Air) when the gas to be measured is air, i.e., when the oxygen concn. is 21%. The circuit sets the voltage Vs (N2) when the gas to be measured is pure gaseous nitrogen, i.e., when the oxygen is 0. Furthermore, the circuit changes the voltage Vs linearly from Vs (Air) to Vs (N2) according to a linear change in the oxygen concn. from 21% down to 0%. The responsiveness is thus improved.

Abstract: PURPOSE: To prevent overcurrent in a magnetron while reducing the size of a power supply by performing PWM control through a first feedback means for feeding back a voltage induced in a transformer inducing a square wave voltage on the secondary through switching action, and a secondary feedback means for feeding back the current of the magnetron.

Filed: 1981-08-06
Abstract: PURPOSE:To extend the life of an excitation lamp in a laser oscillator, by switching the strength of power of the laser light through various filters when the laser light is irradiated to a work to perform the trimming work. CONSTITUTION:The laser light output signal instructed in a processing device 7 is transmitted to a laser oscillator 2 through a laser controller 1 to emit a laser light 9. The laser light 9 is irradiated to the working part for a work through a beam scanner 3 to perform an objective working. In case the strength of power of the laser light 9 is switched as required, a rotary plate 10 to which plural filters 11 are attached is rotated by a motor 12 to allow the laser light 9 to pass through a required filter, and thus, it is switched to a desired power easily and is irradiated to the work 4. Since power of the laser light is switched but the current of an excitation lamp is not changed by a resistor, the life of the excitation lamp is extended.

Title: Preventing mechanism for preventing double-feeding of storage media
Inventor: IWASA HIROSHI
IPC: B41J13/00
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To surely feed only one paper sheet to an image forming apparatus by feeding a storage medium to be fed to an image forming apparatus by co-op eration of a rotating feed roller and a selected friction plate. SOLUTION: When a user selects the kind of a paper sheet according to a preset screen, a terminal outputs a signal for informing of the kind of a paper sheet to a control part. As a selected friction plate 14 is used in feeding, it is disposed just under a feed roller 13 to abut against the roller. So it is necessary to turn a shaft 11 at a designated angle from a designated reference. A motor 12 rotates the shaft 11 by a designated angle indicated by an external signal input from a driving circuit, so that the optimum selected friction plate 14 is disposed just under the feed roller 13 to abut against the roller. The feed roller 13 starts to rotate, thereby feeding a paper sheet to an image forming apparatus.
