Title: Method of preventing thread end from dropping from end face of package
Inventor: UEDA SHIYOUZOU
IPC: B65H55/04
Filed: 1984-02-09
Abstract: PURPOSE:To prevent the end of a thread from the end face of a package in a spinning machine such as, for example, an open-end fine spinning machine, by moving a cradle arm upward after a predetermined time being elapsed from occurrence of thread breakage to isolate the package from a winding drum. CONSTITUTION:In a device for preventing the end of a thread from dropping upon thread breakage from the end face of a package P which is rotatably supported by an cradle arm 11 so that it is made into contact with and driven by a winding drum 12 which continues to rotate even during thread breakage, a thread breakage detecting device 31 detects a thread breakage to issue a thread breakage signal, and therefore, a cradle arm 11 is moved upward after the lapse a predetermined time from the time when the thread breakage signal is generated, to isolate the package P from a winding drum 12. The predetermined time is the time period until the time just after the thread end has passed a nip section, and is determined by dividing an averaged thread path length from the thread breakage detecting device 31 to the nip section with a winding speed. Thus, even after thread breakage, a thread having an end is made into contact with the nip section in the package P, thereby the dropping of the thread end from the end face of the package P may be surely prevented.

Filed: 1995-02-09
Abstract: PURPOSE: To improve the water quality utilizing underground water by installing a sunk filter bed composed of the lowest layer of a water-barrier sheet, an intermediate layer of water permeable solid nonwoven fabric, and the uppermost layer of a filter on the original ground. CONSTITUTION: The sunk filter bed 6 composed of a lowest layer 11 of a water- barrier sheet, an intermediate layer 10 of water permeable solid nonwoven fabric, and an uppermost layer 9 of a filter is installed on the original ground 12. The uppermost layer (filter layer) has a role of filtering underground water. Water which passed through the filter layer is to pass through the intermediate layer 10 (water permeable solid nonwoven fabric layer), and a ground water which did not pass through the filter layer is collected to be utilized. In other words, since the sunk filter bed is installed on the original ground 12, ground water, etc., near the filter bed 6 flows into the filter layer or the water permeable solid nonwoven fabric layer.  In addition, since the lowest layer 11 is composed of a water-barrier sheet, underground water and purified water can be discharged into an optional water area from a conduit 14 without penetrating into an aquifer.

Title: Parallel signal processing circuit, signal processor and signal processing system
Inventor: KOCHI TETSUNOBU
IPC: H04N5/341
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce circuit scale, to accelerate arithmetic speed and to reduce power consumption. SOLUTION: When one terminal of a capacitor 12 is reset by a reset pulse ϕRES at the parallel signal processing circuit of seven inputs, the input terminal of an inverter 6 is almost simultaneously reset. Then, signals V1, V3 and V5 from an input terminal 9 are inverted by an inverter 13 and respectively inputted to one terminal of a capacitor 2. When a signal transfer switch 3 is conducted by a transfer pulse ϕT, signals V2, V4 and V6 are transferred to one terminal of the capacitor 2 and a signal V7 is transferred to one terminal of the capacitor 12. The input terminal voltage of the inverter 6 is changed just for +5/8V when the signal is at an H level or just for -5/8V when the signal is at an L level.  When the sum of seven inputs at the inverter 6 is positive, the H level is outputted to an output terminal 11 of a sense amplifier 5 but when the sum is negative, the L level is outputted there. At the parallel signal processing circuit, the amplitudes of input signals and these signals are weighted as prescribed through respective signal processings corresponding to the size of the capacitor 2 and these input signals are parallelly operated by the sense amplifier 5 at the same time.

Title: Sound signal processing system
Inventor: YAMAGISHI YOICHI
IPC: G11B5/027
Filed: 1989-01-31
Abstract: PURPOSE:To prevent the deterioration of a sound signal when a time base compressibility is altered and the signal is recorded again by altering the time base compressibility executed at the time of re-recording in the state of the time-base-compressed original signal. CONSTITUTION:The signal is recorded on a current track, for example, at 320-fold compressibility. The signals recorded on a reproducing floppy at the 320-fold time base compressibility are successively written to a memory 8 by a clock at approximately 7.16MHz. To dubbing-record the signals on a slave side at the 640- or 1,280-fold time base compressibility, the signal is sub-sampled every other signal or every four signals for the output data from an A/D converter 7, and the sample data are written to the memory 8. Since holding distortion is generated, however, a band is restricted by a digital LPF (low pass filter) 9, and then the data are written to the memory 8. Thus the signal can be sub-sampled every other signal or every four signals, and the deterioration of the sound signal can be suppressed.

Title: Data transmission system for communication control equipment
Inventor: YAMAMOTO TAKEAKI
IPC: H04L69/40
Filed: 1987-02-04
Abstract: PURPOSE:To prevent wrong data from being transmitted by invalidating the wrong sent data and outputting a mark signal if abnormality occurs to data and a data transfer procedure during the transmission of data transfer by a direct memory access system. CONSTITUTION:When an error occurs, the output (signal line 17) of a holding circuit 6 is '1', so an OR circuit 8 invalidates the wrong sent data from a serial output line 14 forcibly and outputs the mark signal ('1'). This is idle and indicates the abandonment of the right to send, and a reception-side device handles the frame as an ineffective frame. Consequently, even if an error occurs in the write cycle of the writing of data read out of a storage part MEM 2 to a parallel resister CR 23a, the erroneous data can not be outputted linealy to a communication line because of a holding circuit 6 which holds the signal indicating the error occurrence and an OR circuit 8 which places the sent data forcibly in a '1' state (IDLE state) with the output signal of the circuit 6.
