Title: Production of magnetic head
Inventor: HANDA SHIYUNJI
IPC: G11B5/265
Filed: 1983-01-21
Abstract: PURPOSE:To make the tracking density much higher by eliminating the pasting of an erasing core from both sides of a recording and reproducing core thereby simplifying the construction and improving the accuracy of the distance between the recording and reproducing gap and the erasing gap. CONSTITUTION:A bulky magnetic core 12 is pasted via a member patterned with thin film magnetic cores 16, 17 and an erasing gap 18 on a non-magnetic plate 21 and on a member patterned with a thin film magnetic core 14 on a non- magnetic plate 19 via a recording and reproducing gap 13 on a bulky magnetic core 11 in a magnetic head of a tunnel erasing type. Then the number of parts is reduced and the distance between the gap 13 and the gap 18 is accurately controlled by the thickness of the non-magnetic plates 19, 21. If the positions of the cores 16 and 17 are adequately deviated in accordance with the diameter of the disc used, the difference in inside rings is eliminated without providing azimuth angle to the gaps 13, 18. The pasting from both sides is further eliminated and the higher track density up to the limit of the thickness of the bulk cores 11, 12 is made possible.

Title: Power transmission device for power assisting type bicycle
Inventor: SEKINE TADASHI
IPC: B62M6/55
Filed: 1988-01-19
Abstract: PURPOSE:To reduce the dimension of the device and improve the outside appearance by installing a driving shaft for a power source and a driver through a one-way clutch which can transmit power from only both driving shaft side to a driven shaft side. CONSTITUTION:If a driver revolution-drives a pedal crankshaft 8 in the direction of arrow A when a motor is in stop state, a driving power is not transmitted because of the action of a one-way clutch 19 between a driven shaft 16 and a worm wheel 20. When the pedal crankshaft 8 is stopped, and the motor is revolved, and the worm wheel 20 is revolution driven in the direction of arrow B through a worm gear 22, the driven power is transmitted to the driven shaft 16 through the one-way clutch 19. At this time, the driving power is not transmitted between the pedal crankshaft 8 and the driven shaft 16 because of the action of a one-way clutch 15. Further, if the pedal crankshaft 8 is revolution- driven in the state where the motor is revolved, the synthetic force of the both driving powers is transmitted to the driven shaft 16. Therefore, a rear wheel can be driven by the driven shaft 16.

Title: Compound testing of multicutoff tank type breaker
Inventor: KOBAYASHI AKIO
IPC: G01R31/333
Filed: 1982-01-25
Abstract: PURPOSE:To enable a short-circuit testing with a sufficient equivalent of a multicutoff tank type breaker by performing a test using a large current source, a first high voltage source connected thereto, a second high voltage source whose voltage peaks in a specified timing and the like. CONSTITUTION:A sample multicutoff tank type breaker 17 is opened to match the phase of a short-circuit current i1 with a large current source 25 to start a trigger cap 8 of a first high voltage source 16 before the zero point t2 of the current i1. An overlapping current i2 determined by a capacitor 7 and a reactor 9 is the same in the polarity as the current i1 and overlaps the current i1 in such a manner that the zero point of the current i2 comes after the zero point of the current i1 is passed. An auxiliary breaker 6 is cut off at the zero point t2 to separate a power source 25. Following the zero point t3 of the current i2, the sum of a voltage generated from a resistance 10 and a condensor 11 and a voltage inverted in the polarity of a condensor 7 provides a restriking voltage V1. At the zero point t3, a difference between a voltage V2 and a voltage V1 as generated with the start of a cap 13 of the power source 27 is applied to a tank 18 as restriking voltage. This enables a short-circuit testing with a sufficient equivalence.

Title: Dictionary retrieving method for character recognizing device
Inventor: NAKAMURA MASAHIRO
IPC: G06K9/48
Filed: 1986-01-20
Abstract: PURPOSE:To shorten dictionary retrieval time by rejecting a corresponding templet when the cumulative value of the parameter distance of an input pattern by distance comparison is larger than a threshold value. CONSTITUTION:A microprocessor 10 accesses a dictionary 11 through a dictionary counter 12 and sets a check point value 1 in a check point register 13. Then, the 1st templet is read out of the dictionary 11 and the microprocessor calculates the distance of an input parameter and cumulates the distance arithmetic value from one dimension of the dictionary as the counter 12 counts up. When the stepping value of the counter 12 becomes equal to the contents of the register 13, a comparator 14 initiates an interruption to the processor 10. Then, the cumulative value is compared with a variable threshold value and when the cumulative value is larger than the threshold value, the corresponding plate is rejected and templet processing is advance. Unnecessary retrieval is interrupted by this rejection processing, so that the dictionary retrieval time is shortened.

IPC: C03B5/20
Filed: 1993-12-21
Abstract: Raw materials are fed into the charging end of a melting section which is heated by electrodes in the glass bath. The melted charge is then clarified under fossil fuel burners in a clarifying section, where the highest temperature of the furnace is maintained, and homogenized in a homogenizing section from which the clarified melt is drawn. Flue gas from the clarifying section sweeps the surface of the melting section countercurrently to the charge and is then used to heat combustion air. Burners in the clarifying section are operated under air starved conditions to reduce nitrogen oxides, while burners in the melting section are operated with excess air to achieve complete combustion.
