IPC: H02M3/28
Filed: 1988-04-04
Abstract: PURPOSE:To make an operational amplifier unnecessary, by employing a current transformer and an output current detecting means operated by an AC/DC converting means in order to detect an output current. CONSTITUTION:A ringing choke converter is provided with a 3-winding transformer 1, a switching means 2, a control circuit 3, a diode 4 and a capacitor 7 while a voltage at both terminals of the capacitor is outputted as an output voltage Vout.

Title: Yarn winder
Inventor: FUKAMACHI SATOSHI
IPC: B65H59/38
Filed: 1984-04-23
Abstract: PURPOSE:To always take up a yarn with fixed low tension by detecting the travel of a movable roller from its original position, which is adapted to move when the tension of a stretched yarn exceeds a specified value, and controlling the speed of feeding a yarn to return the movable roller to the original position. CONSTITUTION:An adhesive yarn F is forcedly drawn out from an original bobbin 1 by a feed roller 2 at a yarn speed corresponding to the rotation frequency, and a designated low tension is applied to the yarn by a movable roller 4 to take up the yarn on a bobbin 5. When the winding amount of a small-roll bobbin 5 increases, the yarn take-up speed increases. If it becomes higher than the speed of feeding a yarn from the feed roller 2, the tension of the yarn F is heightened to move the movable roller downward. The movement is detected by a potentiometer 8, and a control unit 9 is adapted to multiply a variable-speed motor 3, increase the yarn feed speed and lower the tension of the yarn to return the movable roller 4 to its original position.

Title: Controller of vehicle provided with automatic transmission
Inventor: SASAKI KAZUO
IPC: F16H59/44
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To determine the vehicle speed and the road gradient at higher precision in the low-speed range when the same speed sensor is used. SOLUTION: The number of revolutions of an input shaft (a turbine shaft) in a multiple stage speed change gear mechanism 10 formed into a planetary gear mechanism type is detected by a pickup-type revolution sensor S3. The road gradient in the traveling longitudinal direction is determined from the relationship between driving force of driving wheels by turbine torque and the vehicle acceleration to be obtained from the revolution sensor. Since the number of revolutions of an input shaft 13 is considerably increased larger than the number of revolutions of an output shaft 28a in the low-speed range, not only detection of the number of revolutions, namely, the vehicle speed but also determination of the road gradient can be precisely performed.

Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of pause properties, by preventing the increase of the leakage current at the pn junction that the diffusion layer under a field oxide film and the diffusion layer of a trench form while keeping the breakdown strength of an element. SOLUTION: A field oxide film 4 is made on a p-type semiconductor substrate 2, and boron (B) and phosphorus (P) are diffused to form a p+ layer 6 and a p- layer 8 under the field oxide film 4. These p+ layer 6 and p- layer 8 are made by implanting the ion of boron rather deeply with raised acceleration voltage, and implanting the ion of phosphorus shallowly more than the layer implanted with boron and besides near the film face of the field oxide film 4. Furthermore, a trench capacitor which has an n- layer 12 to form a pn junction between the p+ layer 6 and the p- layer 8 is made in the vicinity of the field oxide film 4. Hereby, the field strength of the pn junction is lightened by lowering the concentration of the p- layer 8 in the vicinity of the field oxide film 4.

Title: Checking system for information processor
Inventor: AOYAMA TAKAYOSHI
IPC: G06F11/22
Filed: 1985-04-18
Abstract: PURPOSE:To avoid the transformation of data despite a malfunction of an optional processor by executing every fixed time a program which checks the normalness of the processor. CONSTITUTION:Processors CPU 14 and 15 are connected to a main memory MMU10, and the MMU10 stores the test execution tasks 11 and 12 for test of CPU 14 and 15 and an operating system OS13 which controls both tasks 11 and 12. The OS13 produces the chances to test the first CPU 14 for each fixed time and executes the task 11 independently. Then the CS13 repeats the control by the frequency equivalent to the number of units of CPU 14 and 15 for control to execute the task 12 for test of the next CPU 15. Whe tasks 11 and 12 select errors, an execution stop request is given immediately to the OS13. Thus the OS13 executes immediately the emergency stop processing to save the information necessary for the next rise only and then stops the execution of the OS13 itself.

Title: Insulated core wire twister
Inventor: IWAKIRI TOSHIHIDE
IPC: H01B13/02
Filed: 1990-03-29
Abstract: PURPOSE:To obtain an insulated core wire twister which can detect a very small pinhole securely by a detection part of a very simple constitution by providing a means for moving an electrode consisting of conductive fibers to slide to get in contact with each insulation core wire being drawn and applying a DC high voltage between the electrode and the conductor of the insulation core wire through respective channel. CONSTITUTION:Insulation core wires W supplied from a twister 1 are collected and arranged to pass a detection part 2 of a pinhole checker. A high voltage is applied to the outer circumference of the insulation core wire W by a high voltage electrode 11 of the detection part 2 at the time. The insulation core wire W has an insulation coating B on the outer circumference of a core C. When a pinhole P is generated in the insulation coating B, a gap is produced to the forward end of a carbon fiber brush of the high voltage electrode 11 to generate a spark discharge. When this spark discharge is generated, the high voltage electrode 11 is shortcircuitted with the earth, so the voltage is reduced rapidly. A pulse wave by the voltage reduction is detected by a pulse detecting part 14 of a detection circuit 5', so the existence of the pinhole is checked. When the existence of the pinhole and its position are detected, the insulation core wire is cut and eliminated around the position of the pinhole after completion of a twisting work, thereby only complete products are used.

Abstract: PURPOSE:To obtain a data processing circuit which receives no limit of the upper limit working frequency by providing an output circuit which reads in the output of the 1st delay circuit following an input circuit with the output of the 2nd delay circuit following a logical circuit which decides the data contents. CONSTITUTION:The n-bit series data is read into the 1st and 2nd input circuits 8a and 8b of an input circuit 8 from a data input terminal 2. A condition deciding circuit 9 delivers a deciding signal 9a when the read-in data satisfies the conditions. The 2nd delay circuit 10 delivers a synchronizing signal 10a with a delay of a clock by the input of the signal 9a. While the data read into circuits 8a and 8b are read into the circuit 8b and the circuit 8c with the input of a clock. Therefore an output circuit 11 can read out the n-bit data of circuits 8b and 8c with the input of the signal 10a. Thus the data can be processed regardless of the delay of the circuit 9, that is, without receiving no limit of the upper limit working frequency.
