Title: Prepaid card
Inventor: WATANABE MAKIO
IPC: G11B23/42
Filed: 1987-05-15
Abstract: PURPOSE:To prevent the forgery of a remainder display by having the remainder display symbols of plural printed numerals, characters and the others to show the remainder on a surface and having an embossing projection to be formed at every use in a remainder display symbol corresponding position. CONSTITUTION:A prepaid card 1 has a magnetic strip 2 in which the information of a remainder etc., are recorded, printed numerals 3 to show the remainder and plural embossing projections 4 formed at every use. Remainder information recorded in the magnetic stripe 2 are read by a reader (not shown in the figure) whenever the prepaid card is used, the remainder after a necessary amount is deduced is rewritten to the magnetic stripe 2 by a writing device (not shown i the figure) and the remainder information are recorded again. The remainder display symbols 3 of numerals, characters and the other show a remainder amount numeral '10' shows the full amount of the remainder and numeral '0' shows the remainder 0. The embossing projection 4 is formed on the lower side of the remainder display symbol 3 so that the remainder information recorded in the magnetic stripe 2 can be easily decoded with visual observation.

Title: Mechanical seal
Inventor: WASHIDA AKIRA
IPC: F16J15/34
Filed: 1978-09-26
Abstract: PURPOSE: To provide a mechanical seal, in which flange portion of a driven ring is projected into sealing fluid so that it is held in contact with the sealing fluid on both sides thereof so as to efficiently release heat caused by friction at the sealing end surface, whereby it is enabled to protect the seal ring against wear and cracks.  
     CONSTITUTION: Surface area of the portion of driven ring 9 where it is held in contact with sealing fluid X is increased by making diameter of flange portion 19 larger than that of flange portion 13, so that heat releasing surface area of the ring 9 can be increased and heat caused by friction at sealing end surface S can be absorbed efficiently by the sealing fluid. Therefore, it is prevented that temperature at the sealing end surface S is increased excessively, and at the same time, sheet ring 4, driven ring 9, packing, etc. can be also protected from excessive temperature rise. Thus, condition of friction and lubrication at the sealing end surface S can be improved and wear at the sealing end surface S can be minimized. Further, sheet ring 4 made of ceramics can be protected against cracks.

Title: Electrode needle for corona discharge
Inventor: FUJIWARA TAKESHI
IPC: H01T19/04
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To keep corona discharge at a fixed discharge current for a long time and discharge to an object uniform while holding discharge in a fixed direction by forming a corona discharge electrode needle of alloy containing Ni and Cr at a specified rate, excellent in heat resistance, corrosion resistance and wear resistance. SOLUTION: A corona discharge generator has a discharge electrode needle 1 protruded from an electrode base 2 connected to a high voltage power supply 3 for corona discharge and a ground electrode 4 opposed to the end thereof at a space. The discharge electrode needle 1 is formed of an alloy with a total content of Ni and Cr being 90 wt.%. The alloy which is more excellent in heat resistance, corrosion resistance and wear resistance to corona discharge than other Ni-Cr based alloy allows the discharge electrode needle to be extremely less damaged, or reduced in thickness and lost, at the end, so that a discharge current value is less decreased for a long time and corona discharge to an object is kept uniform.

Title: Drive circuit for liquid crystal panel
Inventor: UCHIDA MASAHIDE
IPC: H04N3/12
Filed: 1988-05-16
Abstract: PURPOSE: To facilitate interface to various digital signal processing systems by turning off an analog switch after charging a source line up to a voltage corresponding to an inputted digital signal and holding the voltage with the capacity or the source line hereafter. CONSTITUTION: An X driver circuit is changed from the liquid crystal off-level to the on-level continuously L times in one horizontal scanning period of a video signal and turns on-analog switches 7 and 10 at the beginning of one horizontal scanning period and charges a source line 15 up to the voltage corresponding to the inputted digital signal and turns off analog switches 7 and 10 thereafter. The voltage is held with the capacity of the source line 15 hereafter. Thus, the inputted digital signal output can be converted to an analog signal, and interface to various digital signal processing systems is facilitated. Unlike a system where an analog line-sequential X driver and a D/A converter are combined, not only fast D/A conversion but also adjustment of an offset voltage is not required.

Abstract: PURPOSE:To reduce horizontal deflection of a work roll by installing a 1st horizontal supporting roll in a side in the before and behind direction of a couple of work rolls offset to a reinforcing roll and also installing 2nd and 3rd horizontal supporting rolls in the opposite side to the above side. CONSTITUTION:A surface length of 1st and 2nd supporting rolls 7, 9 is desired to be a possibly short length; if the length is shorter than a sheet width, stripe patterns are transferred onto a rolled strip 13, so that the surface length is decided to be equal to or a little longer than the max. sheet width.

Filed: 1987-05-18
Abstract: PURPOSE:To perform DMA transfer at a high speed by finishing the accesses of a shared memory and a local memory in a single memory cycle. CONSTITUTION:The head address of a transfer shared memory is received together with the head address of a transferor local memory, and the number of transfer words via an address bus 310. These received addresses and the number of words are set at counters 420, 421 and 422 respectively and at the same time both FF 430 and 431 are turned on. Thus the address of the local memory set at a counter 421 is read out and transferred to the local memory. Then the contents of the local memory are read out and data are written into the address of the shared memory set at the counter 420. These actions are carried out in a single memory cycle. Then said operation is repeated in the frequency equal to the number of words transferred to complete the DMA transfer.

Abstract: PROBLEM TO BE SOLVED: To provide a small and inexpensive distortion compensating circuit showing large distortion reduction effect by installing a pre-distortion circuit, which distorts an input signal in advance to a main amplifier according to the output signal of the main amplifier, so that a distortion component contained in the output signal of the main amplifier is suppressed or reduced. SOLUTION: In a distortion extraction loop L1, a modulator 12 modulates a carrier that is the oscillation output of an oscillator 10, based on the output of a comparator 38 and its result is supplied to a modulator 18 and a main amplifier 14. The output of the main amplifier 14 is inputted to a hybrid 24, and a part is branched/outputted to a demodulator 36 by a coupler 34. The demodulator 36 receives the supply of the carrier from the oscillator 10, demodulates input from the output of the main amplifier 14 and inputs it to the comparator 38. Thus, the coupler 34 does not branch the output of a hybrid 28, but the output of the main amplifier 14 and inputs them to the demodulator 36. Namely, a pre-distortion system is applied, and a processing for improving linearity is executed on the main amplifier 14.
