A positioning apparatus has a stage, guide elements provided on both ends of the stage, and drive elements which are provided at one of both ends of the stage and move the stage along the guide elements. Like linear guide rails 61A, 61B and linear guide bearings 23A, 23B, two guide elements are provided in an area where a ball screw shaft 52 serving as a drive element is placed. One guide element is provided in an area where a non-drive element is provided.

A device is dedicated to generating messages relating to at least one satellite navigation system and to be sent to navigation receivers. This device comprises processor means responsible for generating "description" messages to be broadcast to the navigation receivers from a chosen date and comprising a description of a format of future messages to be broadcast to the navigation receivers from a date after the chosen date.

Provided is a control device for an internal combustion engine, including a crank angle sensor, a cam angle sensor, a real phase angle detector for detecting a real phase angle of a cam shaft based on a detection signal of the sensors, a target phase angle setting unit including a temperature parameter and battery voltage, for setting a target phase angle of the cam shaft based on an operating state of the internal combustion engine, and a phase angle feedback control unit for conducting feedbac...

A cartridge is composed of a cartridge body and a shutter. A hologram recording disk is rotatably contained in a disk recess formed in the cartridge body. The shutter comprises upper and lower shutter plates between which the cartridge body is interposed. The shutter opens and closes openings formed in both surfaces of the cartridge body. When the shutter is kept in a closed position where the openings are closed, the edges of the shutter are inserted into slits formed around the opening. Furthe...

A novel chitinase, a polynucleotide encoding the same, a vector and a transformant comprising the polynucleotide, an antibody against the chitinase, and a screening method for screening a substance capable of modifying the chitinase, are disclosed. According to the chitinase, polynucleotide, or vector, it is possible, for example, to exterminate ticks, or to treat or prevent tick-borne infections such as piroplasmosis, Q fever, or viral encephalitis.

An antitheft device enables a vehicle to continue its operation without reexecuting information transmissions by referring to stored reception information when a power supply is instantaneously interrupted and recovered. The antitheft device includes an operation-equipment limiting part, a switch for sending a first ID code, an operation-equipment operation determining part that receives the first ID code and generates permission information for releasing a limited state of an operation equipmen...

A recording-medium returning mechanism includes: a feed roller, provided to a feed-roller shaft that can be rotated, for coming into contact with a recording medium and feeding it; a hopper including a holder for holding a plurality of recording media stacked, the hopper being located at a position allowing the recording media on the holder to come into contact with the feed roller while being pressed against the feed roller and a position moving the recording media on the holder away from the f...

A controller for a vehicle AC generator that allows the aging test time of a CMOS logic circuit to be reduced is provided. The controller includes a specified signal detecting circuit connected to a third external terminal to detect a specified signal, a voltage selector circuit that generates a voltage selector signal in response to the detection output of the specified signal detecting circuit, and a power supply circuit connected to the first external terminal to output, as internal power sup...

In a remote access server (RAS), the number of logical link resources, which are circuit resources between the RAS and an ISP server, is set greater than the number of physical link resources, which are circuit resources between the RAS and each terminal device. In the RAS, when a particular circuit undergoes a transition to the dormant state, only the physical link resource is released to allow use by other terminal devices while the logical link resource is maintained unchanged in a connected ...

An optical disc access control and storage apparatus containing a rotating plate for storing discs thereon and rotating the same, a first disc-pushing mechanism for moving a disc along its radial direction from the rotating plate to a second disc-pushing mechanism wherein the second disc-pushing mechanism has a positioning slot for positioning the disc, an auxiliary-fixing mechanism for fixing the disc positioned in the positioning slot, a seizing mechanism for seizing the disc, a rotating mecha...
