Title: Motor controller
Inventor: KUNII KEIJI
IPC: G05B11/36
Filed: 1994-12-26
Abstract: PURPOSE: To stabilize operations by improving the precision of tensile force control by generating the vibrating component of speed by differentiating the speed feedback signal of a motor, and adding a current command for controlling the motor by providing the inverse phase of vibrations by inverting the phase. CONSTITUTION: A speed differentiator 14 prepares a vibration suppressing current command Id * corresponding to a speed feedback signal ωR from a speed detector 6 for detecting the rotating speed of a motor 4. In this case, a voltage command VR* to be outputted by a current controller 11 is prepared from the difference of current command ILR*, current feedback signal ILR and vibration suppressing current command Id *. Then, the speed feedback signal ωR contains a vibrating component ΔωR and when that signal is differentiated by a differentiator 14A, the vibrating component ΔωR is provided. In this case, first- order time-lag 14B is provided for correcting phase deviation caused by an arithmetic cycle.  Then, the vibration suppressing current command Id <χ> of the output is made in-phase with the vibrating component, inverts the phase through a subtracter and is applied to a current controller 11 so that torque for suppressing the vibrating component ΔωR can be generated.

Title: Circ signal multiplex high-vision disk
Inventor: KOIZUMI TOSHIO
IPC: H04N5/85
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the deterioration in high-vision videos by wobbling tracks with a ternary three-valued CIRC signal having 3 states; +1, 0, -1 to frequency- multiplex digital audio signals on a high-vision video disk. CONSTITUTION:In the case of a MUSE system, 13MHz is selected as a video carrier. The frequency shift of FM is set at 3MHz. Since the band width of the MUSE signal is 8.1MHz, the lower wave end of the video FM signal exists at 3.4MHz. The conversion from the binary CIRC signal to the ternary three- valued CIRC signal is executed by using 8B-10T. Namely, binary 8 bits are converted to ternary 10 symbols. The symbol rate of the ternarized CIRC signal is increased double-fold, by which the ternarized CIRC signals for another 3CHs can be multiplexed by wobbling. The occupied frequency band of this time is 1.286MHz to 429kHz and the approximation of these second harmonic wave components to the lower wave band of the video FM signals and the exertion of adverse influence are decreased.

Title: Surfactant removing apparatus
Inventor: KODAMA MASATOSHI
IPC: C02F1/58
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To extend the periodic replacing cycle of a cartridge by storing the shower sewage from a water tank in a treatment tank and jetting the air from an air pump as air bubbles to convert a surfactant in the sewage to froth to allow the same to overflow from the upper part of the treatment tank. SOLUTION: Sewage generated by using a shower is stored in a water tank 22 from the shower trap of the floor of a shower room. This sewage is sent to a treatment tank 1 under pressure by a raw water pump 24 when it becomes an almost full state. When a water level sensor detects a set water level and the raw water pump 24 is stopped, an air pump 5 is driven to send air of about 2l/min into sewage through a bubble pipe 7 and jetted from the bottom part of the treatment tank 1 as air bubbles to aerate shower sewage. By this constitution, a surfactant in shower sewage becomes froth to accumulate on the surface of the sewage to overflow from the upper part of the treatment tank 1 before long. Since sewage is sent to an activated carbon tower 1 after the removal of the surfactant, the load of activated carbon is reduced and the replacing cycle thereof becomes long.

Title: Metallic sound absorbing material
Inventor: NAKAMURA HEIHACHI
IPC: B32B1/08
Filed: 1993-12-03
Abstract: PURPOSE:To reduce metallic sound which is generated by a metal pipe or the like when it is struck by sealing sound-absorptive expanded bodies in a hollow section of a metal hollow body. CONSTITUTION:Expanded polyurethane resins 4 are forced into a steel pipe body 1 from a resin raw material injection machine 8. And the resins 4 are solidified and cut to required length, which are inserted into the ends of two steel pipe bodies 1, to which the opposite ends of a pipe joint 3 are opposed, following which an L-shaped notch 10 is engaged with a pin 11 of the steel pipe body l to connect the joint with the body 1. Further a waterproofing cap 12 is inserted into an insertion part of the joint 3 to prevent water from penetrating into the body 1 through a gap in the connecting part of the body 1 and the joint 3. By this method, matallic sound can be absorbed and damped, thereby reducing uncomfortable feeling due to matallic sound and reducing the noises at the time of handling metal pipes.

Title: Tape for adjusting magnetic recording and reproducing device and its forming device
Inventor: SAITO KENJI
IPC: G11B5/455
Filed: 1992-12-21
Abstract: PURPOSE:To easily adjust the relative position of a rotary head and a magnetic tape by constituting the above-mentioned tape in such a manner that prescribed tracks are formed by a magnetic head of the same azimuth angle and are formed in the periods of not reproducing the adjacent tracks at the time of off track. CONSTITUTION:The track format of the tape for adjusting a tape path is 3.81mm tape width in the case of the magnetic tape 11 viewed from the magnetic surface and is formed with the tracks 11a for adjustment at 6 deg.22'59.5'' track angle theta1 on the tape 11. The tracks 11a are recorded at every other track by only the magnetic head of +20 deg. azimuth angle theta2. Namely, the tracks 11a for adjustment of every other four tracks are formed if the tracks of ordinary double azimuth recording are formed. As a result, sufficient spacings are held between the tracks 11a for adjustment and, therefore, the reproduction of even the adjacent tracks at the time of the off track of the reproduction magnetic head does not arise any more. The inclination of the tracks is easily known and, therefore, the relatively positions of the rotary head and the magnetic tape 11 are easily adjustable.
