摘要:
An apparatus for controlling a clutch of a motor vehicle connected to an engine and having a driving and a driven rotating member. The apparatus is capable of controlling an amount of slip of the clutch during starting of the vehicle. The apparatus includes: an engine torque determining device for determining a torque of the engine; a clutch speed monitoring device for determining whether a speed of the driven rotating member has been raised to a level substantially equal to a speed of the engine; a first slip control device for controlling the amount of slip of the clutch such that a clutch torque to be transmitted through the clutch is smaller than the engine torque by a predetermined amount, before the clutch speed monitoring device determines that the speed of the driven rotating member has been raised to the level equal to the engine speed; and a fully engaging device for fully engaging the clutch when the clutch speed monitoring device determines that the speed of the driven rotating member has been raised to the level.

A fuel pump which can suppress fuel bubbles from being sucked into a fuel pressure chamber, and can achieve a stable fuel pressure property. The fuel pump has a pump body formed with a suction passage and a pump operation chamber, and a pressure pump mechanism to pressurize and discharge fuel. The pump body has a lower side wall portion and an upper side wall portion respectively at the vertically lower and upper sides of the inner wall portion forming a suction gallery chamber partly forming the suction passage. The pressure pump mechanism has a valve retaining member having an insertion portion inserted into the suction gallery chamber. The insertion portion has internal suction inlets through which the fuel is sucked from the suction gallery chamber into the pump operation chamber, the internal suction inlets being positioned in the intermediate height area in the suction gallery chamber.

摘要:
A grain diameter controlling crystalline layer comprising crystalline grains of a metal selected from the group consisting essentially of Cu, Ni, Rh and Pt was formed on a substrate. Then, deposited atom layer of at least one element selected from the group consisting of oxygen and carbon was formed on the surface of the grain diameter control layer. A magnetic recording layer was deposited on the atoms deposited grain diameter controlling crystalline layer. Then a magnetic recording medium in which the magnetic crystalline grains has small grain diameter and small grain diameter distribution, and the magnetic recording medium shows increased signal to noise ratio at high recording density.

摘要:
A multilayer coil component is formed such that ceramic green sheets having coil conductors and via hole conductors are laminated. The multilayer coil component includes therein a spiral coil in which the coil conductors are connected in series through the via hole conductors. In plan view in a lamination direction, the via hole conductors are located in positions spaced toward the outer side of the spiral coil, the positions being located near end surfaces in a long side direction of a multilayer body.
摘要:
A pair of members opposed to each other via a gap are commonly used as an evanescent light probe and a writing magnetic head. When the spacing and width of the gap are smaller than the wavelength λ of injected light, highly intensive evanescent light is generated from the gap position of the opposite surface. Magnetic writing is carried out by applying a recording magnetic field from the pair of members to a medium heated by the evanescent light.

A magnetic recording layer is formed on an under-layer comprising a Cu crystalline grain layer and a deposited nitrogen atom layer on the Cu crystalline grain layer surface. Then the magnetic recording layer comprising very small average grain diameter and sharp grain diameter distribution is obtained. The magnetic recording medium comprising the magnetic recording layer shows excellent signal to noise ratio at high density recording.
