Inventor: TABATA MASATAKE
IPC: B64G1/22
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To realize weight reduction, improved capability for forming a good plane surface, and excellent reliability by attaching an offset member vertically onto the plane of each end portion of a pair of expansive elements as connecting means, folding expansive elements so as to face the corresponding surfaces with each other to form a gap therebetween, and allowing a third expansive element to be rotatively stored in the resultant gap. SOLUTION: Among basic expansive panels, for example, two pairs of expansive panels 1, 2 and 3, 4 are connected to be foldable by attaching offset members 5a, 5b each having a predetermined hinges 6a, 6b, to the planes of those expansive panels in the direction vertical thereto. Gaps are generated between the folded expansive panels 1 and 2, and 3 and 4, respectively. The resultant gaps accommodate other expansive panels 1 to 2c, and 3a to 4c. Then, for example, an additional expansive panel 1a can be connected to the basic expansive panel 1 by attaching a hinge 1d to the portion thereof to which the offset member 5 is not attached. A panel 1b can further be connected to the panel 1a using a hinge 1e. Such work is performed repeatedly for the whole structure to form the expansive structure, thus being foldable to be stored in a compact manner.

Title: Aluminum foil for electrolytic capacitor anode and manufacture thereof
Inventor: KATANO MASAHIKO
IPC: H01G9/042
Filed: 1992-08-28
Abstract: PURPOSE:To suppress the generation of a streaked pattern after etching to improve the commercial value by keeping the impurity concentration of Fe, Si, Cu, etc., within a specific range and by using high-purity Al, of which the electric resistivity value at an ordinary temperature is within a constant range. CONSTITUTION:Al ingot with 99.97% or higher purity containing 10-70ppm Fe. 10-70ppm Si and 1-50ppm Cu as impurities is subjected to hot rolling. When the content of impurities such as Fe, Si and Cu is less than a specified quantity, the quantity of deposition of impurities diminishes and the starting point of etching decreases so that an electrolytic capacitor anode foil with high electrostatic capacity cannot be obtained. On the other hand, when the content of impurities such as Fe, Si, Cu, etc., exceeds the specified quantity, the quantity of deposition of impurities becomes too much so that an excessive dissolution occurs in etching. Also, when the electric resistivity of a hard foil at 20 deg.C is within the range of 2.680-2.730muOMEGA.cm, a specific surface area can be improved by etching without increasing a dissolution loss so that the hard foil within high electrostatic capacity can be obtained.

Filed: 1987-10-12
Abstract: PURPOSE:To decrease the number of dip switches and switching elements and to simplify a wiring constitution by storing the combinations of prescribed signal modes into a memory means and selecting these combinations via a selection means. CONSTITUTION:A position is pointed by a pointing device on a tablet and the coordinate position of the pointing device is decided by the operation of a microcomputer 10' carried out based on the output of the tablet. Then the coordinate position of the pointing device is stored in a memory part for combinations of prescribed signal modes of the microcomputer 10'. A coordinate detecting device checks the modes of other systems to be combined and searches the combinations of signal modes coincident with said checked modes out of the memory part of the microcomputer 10'. Then the coordinate detecting device operates the keys 2-7 of a dip switch 20S to designate the address of the relevant combination of the memory part. Thus the signals are smoothly transferred between the microcomputer 10' and other systems through a simple constitution containing a dip switch and a resistance module R20 only. Then it is possible to decrease the number of dip switches and switch elements and to simplify a wiring constitution.

Running of a servo motor is controlled, and a table 2 is moved in a direction X2 from a home position to a pallet table 30 in a manner to perform a simple harmonic motion. In this case, since a second pinion 65 is engaged with a rack 63, the pallet 4 is moved in the same direction X2 as that of the table 2, and when it is moved to the end part of a saddle 8, it is transferred onto the pallet table 30. When the pallet 4 is transferred onto the table 2, a reverse motion to the aboves is effected. This method enables smooth exchange of a pallet, and permits relaxation of an impact.

Abstract: PROBLEM TO BE SOLVED: To reduce the drive loss and to prevent the occurrence of the driving malfunctions and the dielectric breakdown of a gate by suppressing the undesired vibrations of the gate voltage and applying the gate voltage of a proper range to the gate of a MOS-FET. SOLUTION: A vibration suppression circuit 10 consists of a 1st diode 3, a 2nd diode 4 and a capacitor 5, and a MOS-FET 2 and the circuit 10 are unified into a molded package.
