摘要:
A disk apparatus, e.g., a magnetic disk apparatus has a storage medium in the form of a disk which is rotated and accessed, and is designed so as to reduce the occurrence of scratches on the storage medium due to contact between the head and the storage medium while ensuring stable access to the disk-type storage medium. In addition to a main dowel which is provided on a suspension and which supports a magnetic head at a center of the same, an auxiliary dowel is provided on the suspension on the air outflow side relative to the main dowel to limit the tilt of the magnetic head at the time of loading.

A fuel cell power plant comprises a water circulation passage (5) which circulates the cooling water in a fuel cell stack (4). Sodium hydroxide which lowers the melting point of water is mixed with water in the water circulation passage (5) to prevent freezing of the water in the water circulation passage (5). Electrodes (11, 12) are disposed in the water. When the fuel cell stack (4) is running, a voltage is applied between the electrodes (11, 12) such that the positive electrode (11) attracts sodium ions, thereby removing sodium ions from the cooling water supplied to the fuel cell stack (4). When the fuel cell stack (4) stops running, sodium ions which were attracted to the positive electrode (11) are made to diffuse into the cooling water by ceasing to apply the voltage to the electrodes (11, 12).
摘要:
In the air-conditioning system, a primary side to generate heat includes a heat storage and a heat source and produces cool or warm water using an inexpensive commercial power source such as a nighttime power source. A system collaboration unit is disposed between a motor to drive a water pump and a power source. The unit is connected to the motor via a cable. An output from the inverter is connected to the motor via a cable.

A system is provided to recover unutilized energy as electric power in hydraulic turbine power generation. The system includes a heat storage tank, a pump for pumping water from the heat storage tank and to air conditioning loads, a first water feed pipe connected between an outlet of the storage pump and the air conditioning loads, and a second water feed pipe for returning the water discharged from the air-conditioning loads. A hydraulic turbine driven generator is provided on a lower portion of the second water feed pipe at such a position as to recover the potential energy of the water discharged from the air conditioning loads.

The present invention provides a magnetic recording medium with a reduced tendency for a free layer to become thicker near an outer periphery than near an inner periphery of a recording zone as well as provides an information reproducing apparatus which is equipped with the magnetic recording medium and reproduces information according to the magnetization at various points on the magnetic recording medium. A magnetic layer carries information in an outer zone outside a predetermined inner zone around a through-hole. That part of the free layer which is located in the outer zone is thinner near the outer periphery than near the inner periphery.

An optical pickup apparatus and a laser diode chip which can simplify and miniaturize a construction of the apparatus is provided for using a plurality of laser beams of different wavelengths. The laser diode chip is a chip for the optical pickup apparatus in which a plurality of light emitting portions for emitting the laser beams of the different wavelengths in the same emitting direction are formed on a substrate. Light emitting points of the plurality of light emitting portions are located at positions which are different in the emitting direction.
摘要:
When a jam happens at the second printer in a tandem printer system, the printing operation is terminated at the first and second printers. The continuous sheet after establishment of the primary page images at the first printer is reserved between the first and second printers. The first recovery page for the second printer is determined based on the primary page images on the continuous sheet remaining between the first and second printers. Accordingly, it is not necessary to remove the entire continuous sheet remaining between the first and second printers when the printing operation should be recovered. It is possible to minimize the loss of the continuous sheet reserved between first and second printers even when a jam happens at the second printer.
摘要:
An optical pickup apparatus which supports two wavelengths and is amenable to a reduction in size without employing a combining prism. The optical pickup apparatus employs a semiconductor laser device implemented in the form of a one-chip laser diode having two light sources for emitting a first laser beam and a second laser beam at a wavelength different from that of the first laser beam. A photodetector unit has a first detector section for receiving the first laser beam and a second detector section for receiving the second laser beam, and is set at positions at which the first and second laser beams follow return light paths of different lengths from an optical disc to the first and second detector sections.
摘要:
An infrared ray blocking transparent film which can be very thin and have greater transparency and higher adhesion than that of conventional films; the cost for forming the film can be lower due to the reduced amounts of forming materials used for the infrared ray blocking layer, is disclosed. An infrared ray blocking layer is provided on a surface of a base film, by coating conductive materials including indium tin oxide powder and resin; a hard coat layer is provided on a surface of the infrared ray blocking layer; an adhesive layer is provided on a rear surface of the base film. Since resin employed in the infrared ray blocking layer is UV-curing resin including photo-cationic polymerization initiator, thickness of the layer is reduced, and transparency and adhesion thereof are improved.
