Abstract: In applying an optical fiber (1) to a substrate (3) coated with an adhesive a supply of the optical fiber is located wound around a reel (13). The optical fiber is feed in a loose loop (17) providing a fiber magazine from the reel (13) to a collet (9) or nozzle, from which the optical fiber is passed to a hold-down means (11) having a non-rotating bottom surface. The hold-down means (11) presses the fiber against the surface of the substrate (3). The reel (13), collet (9) and the holding-down means (11) are moved so that the contact point at the substrate surface is moved along a desired path, where the optical fiber (1) is to be placed. This allows that the fiber is applied with small radii of curvature and with a minimum of mechanical stress. A fiber cutter (23) is provided upstream the collet (9) and it can cut the fiber at the places where it is to end so that no loose fiber end portions are produced. A fiber feeder (21) is provided behind the cutter (23) to feed more fiber after it has been cut.

Title: Probe for operating surface signal of electronic device and manufacturing method thereof
Inventor: NAKAYAMA YOSHIKAZU
IPC: G01N1/04
Filed: 1999-11-25
Granted: 2001-12-11
Abstract: The purpose of the present invention is to realize a probe of high resolution and high rigidity, high bending elasticity, usable for a scanning type probe microscope capable of image-picking up a surface atomic image of high resolution, and also to realize the input and output probe applied for a high density magnetic information processor. To achieve the purpose, the probe for operating surface signal of electronic device of the present invention is composed of: a nanotube 24, a holder member 2a for holding the nanotube 24, and a fixing means for fixing a base end part 24b of the nanotube to a holder face 2a in a condition where a tip part 24a of the nanotube 24 is projected. The tip part 24a of the nanotube 24 is used as the probe. Also, coating film 29 is formed as an example of the fixing means to coat the base end part 24b of the nanotube 24. If a coating film 30 is also formed on an intermediate portion 24c on the root side of the tip end portion, the strength of the probe needle and the resolution are further increased. As another example of the fastening means, the base end portion 24b is fusion-welded to the holder surface. All or part of the base end portion 24b forms a fusion-welded part so that the nanotube 24 is firmly fastened to the holder. A common nanotube such as a carbon nanotube (CNT), BCN type nanotube or BN type nanotube, etc., can be used as the above-described nanotube. Since nanotubes have a small tip end curvature radius, signals can be operated at a high resolution. Furthermore, since nanotubes have a high rigidity and bending elasticity, they are extremely resistant to damage and have a long useful life. Moreover, since the raw materials are inexpensive, high-performance probes can be inexpensively obtained. Furthermore, such probes can be used as probe needles in scanning tunnel microscopes or atomic force microscopes, or as input-output probes in place of magnetic heads in magnetic disk drives.

Abstract: The present invention involves apparatus and method for providing page messages to mobile radios based on the mobility rates of the mobile radio. For mobile radios that are relatively stationary, page messages are sent to a cell in which the mobile radio resides, while radios which are increasingly mobile receive their page messages on a local area basis. The mobile radio only performs location updates when the situation is optimized for doing so depending upon the mobility of the radio, the introduction of a new cell, the introduction of a new location area, the expiration of a pre-determined time limit and the status of a new cell location flag. A function is defined for location updating on either a locationary basis or a cell basis in accordance with each of the above factors in order to optimize the burden of location area updating and unwanted page broadcasting.

Filed: 2000-02-01
Granted: 2005-02-11
Abstract: The invention relates to a device and a method for temperature control of an optical storage and reading device. When the internal temperature of an optical storage and reading device has reached a specified value, a temperature control device controls a rotation device of the optical storage and reading device to a lower rotation speed, or controls a server control device to a lower tracking loop gain value, or controls a data read/write device of the optical storage and reading device to a lower moving speed and a lower brake slope, so that the optical storage and reading device can stably perform data reading. The temperature control device includes: a sensing device capable of detecting the current temperature of the optical storage and reading device and generating a first temperature signal; a reference device operationally linked to the sensing device for adjusting a pre-determined temperature value and capable of generating a second temperature signal; and a comparison device separately and operationally linked to the sensing device and the reference device for receiving the first and second temperature signals and outputting a comparison signal. When a central processing unit receives the comparison signal, if the comparison signal is larger than a pre-determined value, the central processing unit generates a first control signal to a driving device for the driving device to reduce the rotation speed of the rotation device, or generates a second control signal to the server control device for reducing the tracking loop gain of the server control device or reducing the moving speed and the brake slope of the data read/write device.

Title: Power unit
Inventor: ASAI KOICHI
IPC: H02M5/27
Filed: 2000-02-23
Granted: 2001-10-11
Abstract: A power unit is provided which is capable of controlling electric current to be supplied to a load connected to the power unit, in a flexible manner in dependence on a load condition. Postive and negative converters of a cycloconver are connected to three-phase output windings of a three-phase generator and connected in an antiparallel manner to each other for generating a single-phase alternating current to be supplied to the load. A firing angle control device causes the positive and negative converters to be alternately switched to operate every half a repetition period of the single-phase alternating current, to thereby cause the cycloconverter to generate the single-phase alternating current. A desired wave-forming circuit forms a desired waveform of a drive signal input to the firing angle control device, for causing the firing angle control device to drive the positive and negative converters, such that the output single-phase alternating current has a desired alternating current waveform. An amplitude control circuit changes a shape of the desired waveform in dependence on variation in the load so as to stabilize an output voltage of the cycloconverter. An amplitude-limiting circuit limits amplitude of the desired waveform to a smaller value when the output voltage of the cycloconverter becomes equal to or lower than a predetermined value.
