Title: Wire drawing machine
Inventor: KIKUCHI HITOSHI
IPC: B21C1/14
Filed: 1992-03-04
Abstract: PURPOSE:To attain cooling corresponding to a drawing velocity using a centrifugal force by supplying water and applying cooling from the neighborhood of the rotational center of plural piece of heat pipe arranged in the radius direction. CONSTITUTION:Cooling water is jetted from a water supplying tube 9 toward a heat supplying fin 8 of a wire solidifying part 7 of a heat pipe 3 inside a wire drawing frame 2. The cooling water is held in the heat supplying fin 8, passes through the heat pipe 3 by the centrifugal force caused by the rotation of the frame 2 and cools an evaporating part 6 as the heat generating part. Since the heat pipe 3 is provided nearly horizontally, when the wire drawing frame 2 is stopped, the cooling water does not pass through the heat pipe, the excess cooling is not occurred, and when the wire drawing frame rotates at a high speed, the drawing velocity is fast and the much heat is generated, a large quantity of cooling water is carried to the evaporating part 6 of the heat pipe 3, so the cooling efficiency is increased.

Title: Inverter device
Inventor: MATSUMOTO KEIJI
IPC: H02P23/08
Filed: 1982-03-25
Abstract: PURPOSE:To improve the stability and the reliability of an inverter device without loss of responsiveness by suppressing the output voltage when an operation mode is abruptly varied, thereby suppressing excess current. CONSTITUTION:A polarity discriminator 15 discriminates the polarity of the output of a slip frequency signal amplifier 9, and inputs the output to a voltage correcting circuit 16. The circuit 16 produces an output which is reduced to a value set by the time constant which is determined in advance at the points when the inputs becomes ON and OFF and again reset to the original value at the predetermined time constant. This output is inputted to a voltage instructing circuit 11, and the circuit 11 is varied at the output in proportion to the value of this output. In this manner, the output is suppressed when the operation mode is abruptly altered, for example, from the power drive time of an AC motor 5 to the regenerating time or from the regenerating time to the power drive time.

CONSTITUTION:A printing plate 4 is taken out of a plate holder 3 and is moved to a specified position at the extreme front end of a table 2. Then the rear end of the plate 4 is sucked securely by vacuum force generated from a vacuum hole 6. Next, an adhesive tape 9 pulled out by a specified length is allowed to move and the end of the tape 9 attaches to the surface of a cover film located at the tip of the plate 4. After this, the adhesive tape is caused to stick to the film using a transport roll 16, and then the tape 9 is moved to the rear so that the end of the cover film 4a peels off. Next, the adhesive tape 9 is caused to stick to a take-up roll 12 tightly, and is cut using a tape cutter 14. This results in the release of the plate 4 from the vacuum hole, and the rotation of the transport roll 16 and the take-up roll 12. Subsequently, the plate 4 is moved forward to allow the cover film 4a to peel off completely.

Title: Acoustic processor
Inventor: SASAKI MAKOTO
IPC: H04S1/00
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To easily adjust time alignment by setting/controlling delay time which is to be given to the sound signals of respective channels in an acoustic processing means from the calculation result of distance information between a listening point and respective speaker units. SOLUTION: When a user sets the position of a driving seat as the listening point and an entering operation is executed, a coordinate value (Px, Py) equivalent to a pointer display position at that time is decided as the selected listening point by the process of a control part. Then, the distances to the respective speaker units HL, ML, LL, HR, MR and LR from the point (Px, Py) are calculated. The number of delay samples as delay time which is to be given to the sound signals of the respective channels is obtained. The number of the delay samples is set in DSP and the signals of the respective channels are delayed and outputted in accordance with the number of the delay samples. Thus, time alignment adjustment terminates and all the speaker units are realized in the state where they are artificially in equal distances in the driving seat from that time.
