A sprinkler head of a frame-yoke type is provided. The sprinkler head comprises a disassemblable part including a support, a balance, a movable member and a heat-sensitive body. The sprinkler head also includes elements for preventing dislodgement of the balance from the support. These elements are disposed at a position adjacent where the balance and the support engage with each other. The elements for preventing dislodgement of the balance may include protrusions extending outwardly from each sides of the balance body.

In the present invention, there is provided an optical disk medium wherein a ROM region having data already recorded therein and capable of only optically reproducing (reading) the data as well as a RAM region capable of optically recording and reading out therein and therefrom are interlacedly located in such a positional relationship that enables the substantially continuous and high-speed accessing operation to the read-only ROM and rewritable RAM data, and some of stationary data to be stored suitably in the ROM region are stored in positional relationship closer to some of additional data to be stored suitably in the RAM region which are especially closely related to the some of the stationary data.

In an apparatus for tracking an optical disc, speed in acquiring a steady tracking condition is significant. That is, if the light beam is subjected to feedback while it is positioned in a positive feedback region, e.g., in the middle of adjoining tracks, the track servo system causes an oscillation. Therefore, according to the present invention, there is effected a comparison between the magnitude of signals from two pits disposed offset from the track and a pit on the track to determine the position of the light beam so that the tracking error signal may be inversed when the light beam is positioned in the middle of adjoining tracks. This will operate the tracking system in the negative feedback region to more quickly achieve a stable tracking state.

A tracking servo system includes in addition to a composite servo system composed of a push-pull track deviation detecting loop operative with pregrooves formed in an optical disc and a wobbling track deviation detecting loop operative with intermittently provided wobbled tracking marks, an offset correcting loop for detecting offset component possibly produced due to tilt, deformation and eccentricity of a recording medium or change in optical and mechanical parameters in the course of time lapse to drive forcibly a light spot by applying an electrical offset to cancel out the offset component. In the offset correcting loop, light reflected by wobbled tracking marks provided intermittently or mirror areas formed by interrupting intermittently the pregroove is utilized for detecting the offset component.

Disclosed is a surface structure of an article (1) including multiple protrusions (3) on the surface. A height H of the protrusions (3) is equal to or larger than 5 μm, and equal to or smaller than 32 μm, as well as at least one of a distance P between each two neighboring protrusions (3) and a distance W between each neighboring two of recesses (5) formed between the protrusions (3) is larger than the height H of the protrusions (3).
摘要:
According to one embodiment, an ultrasonic probe has a laminated structure of an acoustic matching layer, transducer layer with arrayed transducers, and backing layer. A transmission/reception unit transmits and receives ultrasonic waves to and from an object via the transducers. A control unit controls the transmission/reception unit to synchronize ultrasonic-wave generation by a specific transducer of the transducers with ultrasonic-wave reception by a different transducer. A phase shift detection unit detects a phase shift between an output signal from the transmission/reception unit and a reference signal, the output signal corresponding to synchronization between the ultrasonic-wave generation and the ultrasonic-wave reception.

In a computer system that can configure a virtual machine being able to transit to a hibernation state, data of a main memory of the virtual machine stored in an auxiliary storage device is reduced. At a point in time when the virtual machine has transitioned to a hibernation state, from consideration as to whether the data of the main memory of the virtual machine stored in the auxiliary storage device is unnecessary, data stored in the auxiliary storage device is rewritten in order to reduce the data.
