摘要:
A computer system includes a plurality of processors, a shared resource being used by the processors, and a storage unit in which management information corresponding to the shared resource is stored. The management information includes a semaphore for each OS managing a task which runs on the processors, a queue in which information for specifying a processor which has requested acquisition of the shared resource is stored in series, and a resource counter indicating a remaining number of the shared resources which can be acquired. Each of the processors includes a counter obtaining section that obtains a value of the resource counter, an acquisition decision-making section that makes a decision as to whether or not the shared resource can be acquired, and a resource acquiring section that stores information for specifying the processor in the queue if decided that it can not be acquired.

The invention provides an input support method and apparatus having the following merits in a communication-type navigation system. That is, when at least one character relevant to, for example, a destination is inputted from a navigation apparatus to make a search in a server system, it is possible to minimize time spent in waiting for a response from the server system. Accordingly, communication time is shortened, and a pleasant environment for input operation is realized by making the most of information inputted by a user. In the input support method in a communication-type navigation system, a navigation apparatus (1) and a server system (4) are connected via a communication network (3). The input support method is comprised of the following steps: a first step of obtaining candidate characters for next input and the number of candidates pertaining to an input character string from the server system (4) via the communication network (3), and storing them into a cache memory (14) provided in the navigation apparatus (1); a second step of, at least when an input character string is updated at the navigation apparatus, searching the cache memory for candidate characters following the updated input character string and the number of candidates pertaining to the updated input character string; and a third step of, when the candidate characters following the updated input character string and the number of candidates pertaining to the updated character string have not been stored in the cache memory as yet, transmitting the updated input character string to the server system.

An image forming apparatus has an image forming unit and a film-heat-type fuser over which a sheet with an unfixed toner image passes and on which are positioned a first temperature-measuring device centered on the fuser so that a sheet always passes over that device and a second temperature measuring device disposed away from the center so that large sheets will pass over the second temperature measuring device and small sheets will not pass over the device when being conveyed correctly. The device also has a temperature control mechanism, a sheet size detector and throughput control, so that the throughput control changes throughput when the sheet size detector determines that a small sheet is being conveyed and the difference between the temperatures of the first and second temperature measuring devices is less than a predetermined value as the sheet passes over the fuser.

The invention provides multilayered polymethylpentene-containing release films, processes for making the same and for their use in preparing articles comprises cured fiber reinforced epoxy, phenolic or polyacrylate compositions which file use as aerospace structural elements. The films have improved release properties when exposed to high temperatures. The films are non-oriented and multilayered comprising a polyamide layer, a polymethylpentene layer and an adhesive interlayer therebetween. The a polyamide layer has a heat stabilizer; and polyamide blend composed of from about 30% to about 80% of a nylon 6 polymer having a number average molecular weight of at least about 40,000; from about 10% to about 30% of a nylon 6,66 copolymer having a number average molecular weight of at least about 15,000; and from about 5% to about 40% of a nylon 6,12 copolymer having a number average molecular weight of at least about 10,000. The a polymethylpentene layer has a heat stabilizer; and at least one polymethylpentene homopolymer, polymethylpentene containing copolymer or a blend thereof. The adhesive interlayer is attached between a surface of the polyamide layer and a surface of the polymethylpentene layer.

In a one-face mode, a first sheet discharge portion arranged on an upper face of an apparatus body, or a second sheet discharge portion arranged in the apparatus body so as to be freely opened and closed is opened, and a sheet forming an image on one surface thereof is discharged to this second sheet discharge portion. In a both-face mode, a sheet forming images on both surfaces thereof is conveyed to the first sheet discharge portion through a sheet discharge path formed by closing the second sheet discharge portion. When it is detected in the both-face mode that the second sheet discharge portion is opened on the basis of a detecting signal from a second sheet discharge portion open and close detecting portion, a controller controls the rotating direction of a forward and reverse rotatable conveying device on the basis of timer information from a timer device at the detecting time and the sheet forming the image on one surface thereof is conveyed to the first sheet discharge portion or the second sheet discharge portion, or a both-face conveying portion.

A laser scanner control circuit which is used for an apparatus for scanning onto a photo sensitive material by a laser beam and forming and image thereon is constructed as a monolithic driver IC onto a single chip. A reset circuit is provided for a sample-hold circuit so as to minimize the laser power when the image forming apparatus is in a standby mode. A circuit to detect an abnormality of the laser power is further provided. Due to this, the safety of the laser power control of the sample-hold circuit is improved. The operation of the sample-hold circuit can be started at a time point when the laser emitting operation is stable.

A display control device includes: a transparent color information storage unit that stores transparent color information; a run-length counter that calculates a run-length specifying the number of consecutive pixels having the same color information; a combination calculation unit that combines the image data for the plurality of display layers; and a combined image display unit that outputs the combined image data to a display device. If the color information for a total of run-length pixels calculated by the run-length counter is a transparent color, the combination calculation unit performs combination by ignoring the image data for the total number run-length of consecutive pixels.

A vibratory gyroscope including a vibrator (10) integrally having a plate-like body portion (11) spreading along a reference plane, three drive arms (12, 13, 14) extending in a first direction from the body portion along the reference plane, and two detection arms (15, 16) extending in a second direction opposite to the first direction from the body portion along the reference plane. The three drive arms are composed of two exciting drive arms (12, 13) that are excited in mutually opposite phases in the reference plane and a non-exciting drive arm (14) located between the two exciting drive arms. Each of the three drive arms has an arm width in a width direction along the reference plane and perpendicular to the first direction. Each of the two detection arms has an arm width greater than that of the drive arm in the width direction, thereby suppressing generation of vibrations along the reference plane.
