Title: Drum type centrifugal dehydrating device
Inventor: KAWAGUCHI TOMOYA
IPC: D06F49/00
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To positively make balance adjustment by filling water to a balancer to start up dehydrating operation even when an eccentric load caused by unevenly distributed laundry is shifted from the opposed position of the balancer. SOLUTION: The position slippage of an eccentric load from the opposed position of a balancer is computed as an eccentric slippage angle θ (S4), and the appropriate allowable value (x) is set according to θ (S6). When the eccentric quantity is the allowable value (x) or less ('Y' in S7), water is filled to a balancer to reduce the eccentric quantity of the whole drum (S10). The larger the eccentric slippage angle θ is, the less the eccentric quantity adjustable by the balancer is, but since the allowable value is made small, balancing water filling is executed only when adjustment by the balancer is positively possible.

Title: Voltage regulator for ac generator in vehicle
Inventor: KUSUMOTO KATSUHIKO
IPC: H02K19/36
Filed: 1993-03-29
Abstract: PURPOSE:To prevent breakage by employing a stranded wire as a conductive part coupling means for a hybrid IC in a voltage regulator and the resin case for the hybrid IC thereby preventing resonance of the conductive part coupling means. CONSTITUTION:A copper or silver wire of O.08mm is stranded by about O.6mm and employed as a conductive part coupling means. When the stranded wire 9 is employed as a conductive part coupling means for a hybrid IC1 and a resin case, even an excess vibration of an engine is absorbed by the stranded wire 9 and the conductive part coupling means is protected against breakage. The stranded wire structure retains the function of the conductive part coupling means even upon partial breakage of the strand thus enhancing the reliability and prolonging the service life. Furthermore, machining process is simplified because no bending work is required resulting in saving of material.

Title: Magnetic rotating arc welding method
Inventor: SAITOU AKIHIRO
IPC: B23K9/08
Filed: 1981-05-08
Abstract: PURPOSE:To make a welding device simpler than heretofore and to stabilize welding by forming a rotating magnetic field that rotates an arc column only on the anode side of pipes to be welded, and forming the strongest magnetic field only near the end face of the anode. CONSTITUTION:An electromagnetic coil 14 is provided only on the anode side of pipes 1, 2 to be welded where the anode point is difficult to transfer and said pipes are welded by the magnetically rotating arc. The strongest magnetic field is only near the anode point and an arc column 16 does not extend longer than an arc column 6 of the prior art as shown right in the figure. At the same time, the arc column 16 is bent at a sharp angle near the anode end face and is easier to be radiated of heat, resulting in small and regular transfer intervals of the anode point. Since there are no rotating magnetic fields on the cathode side, the magnetic blow of the cathode is small and the rate to be blown to the axial center side of the pipes is reduced. Therefore, the above-described ratio can be adjusted by adjusting the position between the end faces of the pipe and the coil 14. This method permits welding of thick-walled pipes as well which are heretofore difficult to weld.

Title: Arithmetic processor
Inventor: TANAKA HIDEO
IPC: G06F7/50
Filed: 1990-03-19
Abstract: PURPOSE:To improve the computing accuracy when a fixed point arithmetic is carried out by using an exponent part computing element and a mantissa part computing element which are applied to a floating point operation. CONSTITUTION:In a fixed point arithmetic mode, the arithmetic data inputted to both input data store registers 1 and 2 are inputted to a higher rank digit computing element 3 in the higher rank digits Ae and Be corresponding to the exponent part data and also inputted to a lower rank digit computing element 5 in the lower rank digits Am and Bm corresponding to the mantissa part data with a signal C showing the fixed point arithmetic of a control circuit 8 respectively. Then the operations are carried out via both elements 3 and 5. In this case, a carry signal B produced by the element 5 serves as a carry input to the lowest rank digit of the element 3. Then a selection circuit 6 selects the arithmetic result of the element 3 based on the signal C of the circuit 8. The result of the element 5 is stored in an arithmetic result register 7 as the data on the lower rank digits. Meanwhile the output of the circuit 6 is stored in the register 7 as the data on the higher rank digits. Thus it is judged that a fixed point arithmetic is carried out with the data length equal to the sum of the bit length of the exponent part data and that of the mantissa part data.

IPC: H01H1/18
Filed: 1989-03-24
Abstract: PURPOSE:To increase the current capacity of contacts without increasing the size of contacts to a great extent by installing a plurality of contact parts in the form of round rod at the tip of a stationary contact in such an arrangement that they mate with a pair of moving contacts and are dislocated one another in the longitudinal direction of the moving contacts. CONSTITUTION:At the tip of a stationary contact, a plurality of contact parts 16a, 16b in the form of round rod are installed in such an arrangement that they mate with a pair of moving contacts 11, 12 and are dislocated one another in the longitudinal direction of these moving contacts. Therefore, eventual increase of the current causes merely divergent flow to the contact parts 16a, 16b, and the emission itself of the contact parts 16a, 16b remains lesser, and it is now practicable to increase the current supply capacity without requiring enlarging the section area, which liberates risk of enlarging the height of the contact. Thereby the current capacity of the contact can be increased without requiring enlarging the contact dimension to a great extent.

IPC: G02B6/30
Filed: 1995-03-03
Abstract: PURPOSE: To simplify the work to protect the entire part of optical parts by coating these optical parts including the optical path junctures between the optical parts with an adhesive so as to cover the surfaces of the optical parts on both sides. CONSTITUTION: The optical parts 10, 20, 30 are immersed into the adhesive 52 in an uncured liquid form and at least the optical connecting area is sunk under the liquid surface of the adhesive 52. The optical parts are aligned in the state of embedding the parts into the adhesive and thereafter, the adhesive 52 in cured. The alignment is executed by aligning the end faces of the optical fibers, more preferably the centers of the core, thereby minimizing the optical connection loss and finely adjusting the mutual positions until the light power to be transmitted is maximized. A UV adhesive of an epoxy system or acrylate system having the refractive index approximate to the refractive index of the cores, etc., to be aligned is used for the optical adhesive 52.  In such a case, the alignment is executed in the state of immersing the optical parts into the optical adhesive 52 and, therefore, the subsequent occurrence of misalignment by the intervention of the adhesive between the end faces of the optical parts like in alignment in the air does not arise any more.
