Abstract: A capacitive electronic pen includes a housing, a core body, and a peripheral electrode. In the capacitive electronic pen, the core body includes an electrode core formed of a conductor having a spherical section and a shaft center section. The spherical section of the electrode core is not surrounded by the peripheral electrode and is disposed on a tip (distal) end of the capacitive electronic pen protruding from one opening in the axial direction of the housing. The shaft center section of the electrode core has multiple portions that vary in thickness (a cross-section size) including a thin portion, which coupled with the spherical section, and a thick portion. When the core body is fitted to the core body holder, at least a portion of the shaft center section of the electrode core is thinner than the diameter of the spherical section of the electrode core.

Abstract: In a case in which an electronic pen main unit made into a cartridge is held movably in a casing, electrical connections between the electronic pen main unit and electronic circuit components of the casing are reliably established. The electronic pen main unit is fitted to a fitting part disposed in a casing of an electronic pen in which the pen tip side is made to be an opening and is housed in a state of being movable in a hollow part of the casing by a movement mechanism that moves the fitting part in the axial center direction of the casing.

Abstract: A cartridge-type electronic pen main body includes a conductive center electrode and a peripheral electrode disposed around the center electrode. The peripheral electrode includes a tapered part on a pen tip side and a cylindrical shaped part on an opposite side along an axial direction. When the cartridge-type electronic pen main body is in use, one end of the center electrode forming a pen tip is projected to the outside from an opening of a cylindrical housing of an electronic pen, and a portion of the tapered part of the peripheral electrode is also projected to the outside such that both the one end of the center electrode and the portion of the tapered part of the peripheral electrode are projected beyond a distal end of the cylindrical housing to capacitively couple with a sensor surface while the cylindrical shaped part of the peripheral electrode remains within the cylindrical housing.

Abstract: A clutch mechanism is provided between a drive wheel and an electric motor. In a high vehicle speed region, the electric motor is decoupled from the drive wheel to prevent the electric motor from over-speeding. In the high vehicle speed region, in which the clutch mechanism is switched to a disengaged condition, rotation speed control is executed on the electric motor when a state of charge falls below a predetermined lower limit value, and a motor rotation speed is maintained at a target rotation speed on a lower rotation side than an upper limit rotation speed. Further, the clutch mechanism is switched from the disengaged condition to a slip condition. Hence, a limited power generation torque is supplied to the electric motor, and thus the electric motor can be controlled to a regeneration condition while suppressing the motor rotation speed to or below the upper limit rotation speed.

Abstract: A motor transmission apparatus is provided between a transmission output shaft coupled to a drive wheel and a motor shaft coupled to a motor/generator. The motor transmission apparatus includes a first power transmission path that is switched to a power transmission condition by a high clutch having a clutch oil chamber, and a second power transmission path that is switched to a power transmission condition by a low brake having a brake oil chamber. Working oil discharged from an oil pump is guided to an oil passage switching valve via an output control valve. The working oil is distributed to one of the clutch oil chamber and the brake oil chamber by the oil passage switching valve, and therefore interlocking, in which the high clutch and the low brake are engaged simultaneously, can be avoided.

Abstract: In a heat exchanger having a core portion in which aluminum flat tubes and aluminum fins are disposed alternatively and brazed with each other, each fin has one side portion located at one side of the tube and the other side portion located at the other side of the tube. The one side portion of the fin is higher in pitting potential than the other side portion of the fin, and the pitting potential difference between the one side portion of the fin and the other side portion of the fin is 40 to 200 mV. The pitting potential difference can be formed by the Zn concentration difference in the aluminum alloy constituting the fin.

Abstract: This invention relates to a method of manufacturing an aluminum heat exchanger tube. In forming a thermally sprayed layer 21 on a surface of an aluminum flat tube by thermally spraying Al—Si alloy thermal-spraying particles, quenching the thermally sprayed thermal-spraying particles in a molten state to make them adhere to the tube core 2a. The surface of the thermally sprayed layer 21 is smoothed with, e.g., reduction rolls to form a brazing layer 20. With this method, brazing defects due to fin detachment, erosion to the tube of the brazing material, etc., can be prevented, resulting in good brazing performance.

Abstract: A method of manufacturing an electrode sheet for capacitors comprises the step of forming a sprayed layer of an Al-valve action metal alloy on at least one surface of an aluminum foil (2) by thermally spraying Al-valve action metal alloy powder on the surface of the aluminum foil. At the time of the spraying, a porosity content rate of the sprayed layer (3) is controlled to 20 vol % or less by melting at least a matrix Al phase of the alloy. The electrode sheet for capacitors manufactured by the method can decrease the porosity content rate of the sprayed layer, which in turn can secure less leakage current and larger capacitance.
