摘要:
An alcohol density sensor for detecting an alcohol density in mixture fuel composed of petroleum-fuel and alcohol is installed in a fuel tank of an automotive vehicle. The alcohol density sensor includes a pair of electrodes immersed in the mixture fuel and a conductor portion for connecting the electrodes to a control unit having a circuit board. The conductor portion is composed of a first conductor portion integrally formed with the electrode and a second conductor portion connected to the first conductor portion. The first conductor portion is led out of a casing containing the electrodes and liquid-tightly sealed at a first through-hole formed in the casing. The second conductor portion is led out of the fuel tank through a second through-hole formed in the fuel tank. Since the first through-hole is sufficiently sealed to prevent pressurized mixture fuel in the casing from leaking into an inner space of the fuel tank, sealing of the second through-hole can be simplified.

Provided is an electric actuator capable of preventing the release of particles from the body thereof. The electric actuator includes a body made of an elongated enclosure; a slider configured to move in a reciprocating manner along a lengthwise direction of the body; an opening formed in a side surface of the body to correspond to a moving path of the slider; a dust seal band provided to cover the opening; and a pair of electrodes protruding from the body at opposite sides of the opening toward the outside of the body and extending in the lengthwise direction of the body with the opening being interposed between the pair of electrodes. Positive potential is generated in the upper electrode of the pair of electrodes and negative potential is generated in the lower electrode of the pair of electrodes.

One sensor constituted of a light emission element and a light-receiving element is provided in a path through which a wafer is transferred. The sensor is positioned so that the wafer passes through an area between the light emission element and the light-receiving element. Coordinates of the center of the wafer are calculated based on encoder values obtained when the wafer starts passing through the sensor and when the wafer completes passing through the sensor, position data of wafer transfer means corresponding to the encoder value, and the diameter of the wafer; and thereby the amount of positional deviation of the center of the wafer from a reference position is calculated.

Object A substrate processing apparatus is provided, which comprises a processing vessel adapted to provide a process to a substrate, an ambient atmospheric carrying chamber, and a functional module located on a carrying route of the substrate to be carried by a carrying means in the ambient atmospheric carrying chamber, wherein bad effect on the functional module due to particles and/or corrosive gases to be generated due to contact of the ambient air with the substrate after having been processed can be avoided. solution The substrate processing apparatus, adapted to provide a process, such as etching, to a wafer, comprises the processing vessel, the ambient atmospheric carrying chamber, and the functional module, such as an orienter 4. With the process to be provided, matters having potential to generate corrosive gases or the like due to contact with the ambient air are attached to the wafer. In the ambient atmospheric carrying chamber, a first air stream creating means 15a, 15b, 15c is provided. In the functional module, a second air stream creating means (FFU 60) is installed to create a stream of cleaned air directed toward the ambient atmospheric carrying chamber 14 from the functional module 4, by taking in the ambient air from a clean room.

An oil deterioration detection apparatus includes a sensor, an evaluation circuit, and a malfunction detecting circuit. The evaluation circuit has a determination circuit. The malfunction detecting circuit has a resistor and a switch. The evaluation circuit evaluates a condition of the oil based on a normal voltage. The normal voltage is measured when the switch is opened so that the resistor is not electrically conducted. The determination circuit determines whether the sensor malfunctions based on a relation between the normal voltage and a divided voltage. The divided voltage is measured when the switch is closed so that the resistor is electrically conducted in parallel with the sensor.

A recording and playback apparatus according to the present invention includes a duplicating section for duplicating music data from a music CD in a CD read-out section onto a hard disk and a preserving section which, if duplication by the duplicating section is interrupted, preserves TOC information identifying the music CD and duplicated-music-data information identifying duplicated music data such that the TOC information is associated with the duplicated-music-data information. The recording and playback apparatus further includes a playback section for playing back music data stored in the hard disk. When a music CD having a history of interrupted duplication is placed in the CD read-out section, the duplicating section resumes duplication onto the hard disk based on the TOC information and the duplicated-music-data information preserved in the preserving section.

A raindrop detecting apparatus has a temperature sensor, an EEPROM, a processor and a raindrop sensor. A temperature characteristic data is defined by a first temperature data of the temperature sensor and a first output data of the raindrop sensor produced at a first temperature condition, and stored in the EEPROM. The processor updates a raindrop detection threshold by using the stored characteristic data, a second temperature data and a second output data produced at a second temperature, when an engine is started under no-raindrop condition. The processor compares an output data of the raindrop sensor with the raindrop detection threshold to detect a raindrop, while converting at least one of the characteristic data and the output data in correspondence with a temperature data produced at a raindrop detection time.

A casing accommodating the heater core comprises a main body formed by first and second casing elements joined together at their peripheral edges, and a third casing element detachably joined to the main body and formed with hot air outlets. Part of the peripheral edges of the first and second casing elements cooperate to define an opening at which the third casing element is joined to the main body. The opening is exposed to the outside when the third casing element is detached from the main body, and through which the heater core can be removed from and fitted into the casing with ease.

In this vacuum processing apparatus, four process modules and four load-rock modules are arranged in clusters around a two-stage conveyance vacuum chamber. In the apparatus, the entirety of the second stage of the vacuum conveyance chamber is a third vacuum conveyance area and the third vacuum conveyance area extends from the second stage to the first stage through an aperture to enter between first and second vacuum conveyance areas. A third vacuum conveyance robot has: left and right-side conveyance units, which can move straight in the depth direction in the second stage of the third vacuum conveyance area; and left and right-side conveyance units, which can move straight in the vertical direction, i.e. can move up and down, in the aperture of the vacuum conveyance area.
