Title: Conductive transfer sheet
Inventor: KUWABARA NOBUO
IPC: H05K3/02
Filed: 1987-08-17
Abstract: PURPOSE:To provide a conductive transfer sheet presenting a relatively low surface resistance value after it is transferred, having excellent conducting properties and capable of keeping its conducting properties even in overlapped parts and giving practically effective electromagnetic wave shielding effect to moldings of plastic or the like, by depositing a conductive protecting layer, a vapor-deposited metal layer and a conductive adhesive layer on the surface of a substrate having mold releasing properties. CONSTITUTION:A transfer foil formed on the surface of a substrate 1 having mold releasing properties is composed of three layers: a conductive protecting layer 2, a vapor-deposited metal layer 3 and a conductive adhesive layer 4. Thus, a conductive transfer sheet is provided with the transfer foil produced by forming resin thin films having resonable conducting properties on the top and rear faces of a vapor-deposited metal layer 3 having good conducting properties. When such transfer sheet is transferred to an object material, the surface of the material can be provided with a continuous good-conducting coat film by the vapor-deposited metal layer 3. Further, since the adhesive layer 4 and the protecting layers 2 also have conducting properties, the good-conducting properties given by the vapor-deposited metal layer 3 are kept effective even in the places where the transfer foils overlap each other. Thus, a practical shielding effect to electromagnetic waves can be obtained.

Filed: 1984-09-28
Abstract: PURPOSE:To enhance responsiveness making the size compact by preventing the transmission of torque to the turning shaft of armature enabling the carrier which holds the support pins rotatably pivoting the epicyclic gear to be turned by the torque added to it in the reverse direction when the output turning shaft is reversely energized. CONSTITUTION:When an armature 3 is energized, the turning shaft 3a of the armature rotates in the counterclockwise, and torque in the counterclockwise direction is added to a carrier 19 via an epicyclic gear 8 and supporting pins 9. And the rotation of the carrier 19 is checked by the engagement of a projected part 19a and a stop piece 23 to be engaged, and the revolution of the gear 8 is checked. Thus, checked by the rotation of the gear 8, the rotation of internal gear 26 and an output turning shaft 6 are decelerated in the clockwise direction, and the engine is started by means of a pinion 27. After starting the pinion 27 is inversely energized by a ring gear 18, and further the gear 8 is inversely energized to rotate the carrier 19 in the clockwise direction. And the gear 8 revolves to prevent the transmission of torque to a spur wheel 7, and the shaft 3a performs no load free rotation.

Title: Magnet and apparatus of the same
Inventor: ISHINO TAKESHI
IPC: H01F7/02
Filed: 1981-12-21
Abstract: PURPOSE:To enhance strength of poles by employing 3-pole structure of the first pole surface and the second, third surfaces which cross the first surface and are magnetized by the second pole in the opposite polarity to the first surface. CONSTITUTION:A magnet 10 is a plastic magnet mold, rubber maget mlod or ferrite sintered material having the sectored cross-section obtained by dividing a cylindrical body. The magnet 10 has the orientation of magnetic particle starting from the arc surface 11 which will become the pole surface and extending to both side surfaces 12, 13 which are crossing the arc surface 11 and opposing each other. Thus, the first pole is magnetized, while the second pole of the opposite polarity is magnetized on both side surfaces 12, 13. In case a magnetic roller as a magnet device is formed in such a manner that the polarity of poles of the pole surface is opposed alternately by such magnet 10, the magnetic path of maganetic flux becomes short and the leakage flux is also reduced. Accordingly, the strength of magnetic pole formed on the circular arc 11 can be enhanced sufficiently.

Title: Alkaline storage battery activation method
Inventor: TERASAKA MASAYUKI
IPC: H01M4/32
Filed: 1992-07-31
Abstract: PURPOSE:To improve the battery's property, especially, the battery's capacity by properly reacting a sort of cobalt powder which is abided to a nickel positive pole and trivalent or more and dischargeable with metal cobalt powder. CONSTITUTION:After a storage battery is assembled, the storage battery is left until the positive pole potential becomes the potential equivalent to the equilibrium potential of Co/Co(OH)2 and then a first charge and discharge is carried out. Consequently, a sort of cobalt powder which is added to the positive pole and trivalent or more and dischargeable accelerates oxidation of metal cobalt powder. Since the battery is left until the positive pole potential becomes the potential equivalent to the equilibrium potential of Co/Co(OH)2, the metal cobalt powder becomes susceptive to pre-ferential electrochemical oxidation. During the first charge of the storage battery, the electrochemical oxidation reaction of the metal cobalt powder thus proceeds surely and the use efficiency of the metal cobalt powder is improved. As a result, the use efficiency of nickel active material is heightened and property, especially, capacity of an alkaline storage battery having the nickel positive pole is improved.

Title: Agc device
Inventor: KISHI TAKAHIKO
IPC: H03G3/30
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To realize high speed response characteristic and to reduce distortion by minimizing AGC control rate when an input signal level becomes less than the threshold of AGC and raising AGC control rate with the lapse of time. SOLUTION: When the input signal voltage level to an AGC device drops, input voltage drops lower than the capacitor voltage of an integration circuit 4 and a voltage difference exceeds the threshold, a time constant variable control circuit 7 controls the resistance values of the variable resistors R1 and R4 of the circuit 4. The time constant of an integration circuit 6 becomes a maximum decided by the series resistance values of the resistors R4 and R3 becoming the maximum resistance value and by the capacity of a capacitor C2. Since the AGC control rate of the AGC control circuit 2 becomes a minimum, follow-up speed against the change of the AGC input signal voltage level becomes slow.  Then, the circuit 7 where the input signal voltage level is descending reduces the resistor values R1 and R4 with the lapse of time and consequently the AGC control rate of the AGC device gradually becomes fast. Thus, the high speed response characteristic can be realized and distortion can be reduced.

Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To execute communication by specifying 'another beacon' where a vehicle is predicted to travel in the case of dividing and obtaining remaining data at the point of time at which the vehicle leaves the communication area of a beacon and enters the communication area of the other beacon, as the vehicle can not receive large amount of data from one beacon. SOLUTION: If it is considered that data can not be simultaneously transmitted to an on-vehicle communication equipment, and it is predicted that the vehicle also travels thereafter along a road in the same direction, beacon communication equipment 1 specifies another beacon communication equipment 1 on the road along the same direction and transmits information for specifying the remaining data to the 'other beacon communication equipment 1'.

Title: Method for working clad material
Inventor: HAYASHI AKIRA
IPC: B21D28/02
Filed: 1992-07-31
Abstract: PURPOSE:To prevent the exfoliation of a side face part and to obtain a punched piece without warp by pressing and heat-processing the punched part after punching a clad material in the direction of a lamination with a drop-through blanking method. CONSTITUTION:Because a drop-through blanking method is applied in a punching process, a punched piece 13 is dropped downward by being received a friction of only one direction between the space with an internal wall surface of a die 12. Therefore, the exfoliation between each metal of the side face is prevented. Further, because the warp of the punched piece 13 generated during the punching time is corrected on the next press process, so the trouble is nothing. More, because the residual stress inside the punched piece 13 generating during the punching time is relaxed on the next heating process, so the trouble is nothing. Therefore, the punched piece 13 without the side face exfoliation and the warp, and with little residual stress can be manufactured with the well yield. As a result, when it is used as a heat sink material, the radiating property of a ceramics package can be kept and the quality can be improved.
