Title: Preventive method and its device of slit distortion in metallic band plate
Inventor: KOJIMA MASAYASU
IPC: B23D19/02
Filed: 1984-06-25
Abstract: PURPOSE:To prevent a strip from generation of slit distortion, by forming either one of an upper blade or a bottom blade into a rotary blade while the other one into a linear fixed blade and cutting the strip running on a surface of the fixed blade so as to prevent a width warp from being generated on the strip while it is slitted. CONSTITUTION:A slitter equips an upper rotary blade 7 and a bottom linear fixed blade 9'. The blade 9' horizontally forms its upper surface in the distance from a point P to a cutting finish point Q.

IPC: H05G1/20
Filed: 1989-05-26
Abstract: PURPOSE:To miniaturize and lighten a high pressure transformer so as to obtain a small x-ray photographing device by converting an alternating voltage to a direct voltage by means of a rectifying circuit, and converting the direct voltage to a high frequency alternating voltage by means of an inverter, and boosting the high frequency alternating voltage to produce a high voltage, in a high voltage generating device. CONSTITUTION:A voltage to be applied to X-ray tubes 50a, 50b is generated by converting an alternating voltage to a direct voltage by means of a rectifying circuit 21, and converting the voltage to a high frequency alternating voltage by means of inverter circuits 300a, 300b (300) and applying the high frequency alternating voltage to the first side of high pressure transformers 40a, 40b(40) to produce a predetermined high voltage on the secondary side, and rectifying and smoothing the alternating high voltage; i.e., since the frequency of the voltage applied to the first side of the high pressure transformer 40 is made higher than a commercial power source frequency by the inverter circuit 300, the applied voltage time product is smaller than if a voltage of a normal commercial power source frequency is applied, and so the cross section of the transformer iron core can be small, which enables miniaturization and weight reduction of a high pressure transformer. Miniaturization of the x-ray photographing device is thus achieved.

Filed: 1987-05-29
Abstract: PURPOSE:To easily diagnose the trouble of a logic integrated circuit by simulating the trouble while regarding wiring which can be observed by an electron beam tester equivalently as an output terminal, and generating a trouble dictionary. CONSTITUTION:The node of the uppermost wiring within a suspicious range on a LSI tester which is made clear by trouble diagnosis is regarded as the equivalent output terminal. This can be carried out by using logical connection information and mask pattern information 16 in a design data base 14. Then a trouble simulator 22 generates the trouble dictionary 20 for the electron beam tester from the test vector 19 of a test database 18 and logical connection information 17 which has the equivalent output terminal of the design data base 14. The electron beam tester 11, on the other hand, gathers observed images 21 in an observation zone. The images 21 are matched with a design logic map generated from the information 16 to know the name of the node of the uppermost layer wiring and its logical state. Then the dictionary 20 and images 21 are matched to extract trouble candidates. This dictionary 20 is used to specify a trouble position at a high speed.

Abstract: PURPOSE:To obtain a high-purify sulfated sugar efficiently in a short time, having anti-blood coagulating activity and antiviral activity, etc., by treating a solution containing both sulfated sugar and inorganic salt using a reverse osmosis membrane to separate the inorganic salt to effect purification. CONSTITUTION:A mixed aqueous solution containing both sulfated sugar and inorganic salt is introduced into a reservoir tank 1 followed by adjusting the concentration of the sulfated sugar to 1-50wt.%, and the resultant solution is fed, into a reverse osmosis membrane module 4 through a pump 2 followed by applying pressure to the solution through a retentate valve 5 to enforce the penetration of the inorganic salt together with the water through the reverse osmosis membrane by crossflow technique to remove both the salt and water, which are discharged via an outlet A. The sulfated sugar is returned again to the reservoir tank 1, thus resulting in increasing the purity of the sulfated sugar in the tank 1. This operation is repeated continuously to obtain a high- purity sulfated sugar, which is drawn via a relevant port B, thus obtaining the objective high-purity sulfated sugar through efficient desalting.

Title: Vehicle with auxiliary power
Inventor: TANAKA TATEAKI
IPC: G01L3/14
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To detect an accurate human power drive force by building a torque detection part for detecting the bigness of the human power drive force consisting of a magnetostrictive element in the hub of a wheel. SOLUTION: When a human power is applied to a pedal 5, a magnetostrictive element 43 is shrunk in response to the bigness of a human power drive force detected by a torque detection part. Meantime, as the magnetostrictive element 43 forms the core of a coil 44, the inductance of the coil 44 is changed. Therefore, the inductance of the coil of a rotary side viewing from the coil B 48 of a rotary transformer is changed by the strain of the magnetostrictive element 43, as the coil 44 is connected in series electrically with the coil A46. Therefore, the change of the inductance by the strain of the magnetostrictive element 43 can be converted to a electric signal. By utilizing this output, the torque of the human power can be detected. Accordingly, the processing of the input/ output to/from a control circuit is simplified and the accurate human power drive force can be detected.

Abstract: PROBLEM TO BE SOLVED: To continuously ensure stable sealing of a seal device for use in sealing reciprocating or rotating portions even under higher temperature and pressure by preventing the blowby of pressure from the sealing surface of its seal ring and the damage to its O ring when, for example, the seal ring is formed with a notch. SOLUTION: A seal device 10 comprises a second member 12 which relatively reciprocates or rotates with respect to a first member 11, an annular recessed groove 15 formed in the first or second member, and a seal ring 16 and an O ring 17 fitted into the annular recessed groove 15. The seal ring 16 is formed at its both side faces 16A and 16B with annular circumferential recessed grooves 16C and 16D for accumulating pressure therein respectively. The pressure accumulated in the pressure accumulating recessed grooves prevents the close contact of the seal ring side faces 16A and 16B with side walls 15A and 15B of the annular recessed groove 15 respectively and thus facilitates the induction of pressure toward the O ring 17.
