Abstract:
A technique that can make a heat radiation effect higher and makes even a transmission voltage of an ultrasonic diagnostic apparatus higher and then makes a diagnostic depth deeper is disclosed. According to this technique, an ultrasonic probe has: a plurality of piezoelectric elements 1 which are long in an X-direction, are arrayed in a y-direction and transmit and receive ultrasonic waves in a z-direction (diagnostic depth direction); a plurality of ground electrodes 2 and signal electrodes 3 which are placed on the front surfaces and the rear surfaces of the individual piezoelectric elements, respectively; a plurality of signal electrodes 4 for extracting respective signals from the individual signal electrodes; a backing load member 5 which has a function for mechanically holding the piezoelectric elements through the signal electrodes and attenuating the unnecessary ultrasonic signal as necessary; a plurality of sheet-shaped heat conduction members 6 which are embedded inside the backing load member and positively transmit the heat generated from the piezoelectric elements; and a heat radiating block 7 which is linked to the heat conduction members on the rear side of the backing load member and radiates the heat transmitted through the heat conduction members.
Abstract:
A snug fitting apparatus for improving the finished quality of a tire assembly 1 without sacrificing productivity, including a first pressing member 25 (25a) adapted to be pressed against the ground contact surface F of a tire assembly 1 and a second pressing member 25 (25b) adapted to be pressed against the ground contact surface F to receive the radial reactional force of the ground contact surface F. Measuring device is provided to read variation in the reactional force. As a result, a large, expensive uniformity checking machine is made unnecessary, making it possible to assure quality for all the quantity of tire assemblies 1 on the production line and to fully automate the process.

Abstract:
The invention for printing by a printer in accordance with a requesting order of jobs from clients when an error occurs in a server or the server is shut-down. It is possible to reconstruct a print system in which each client computer spools print data, only job information is transmitted to the server, and the server performs an order control, wherein when an abnormality occurs in the server, the client computer set as a reserve server functions in place of the server and each client computer confirms whether the job registered by itself has correctly been registered or not, thereby enabling a printing process to be normally performed.
Abstract:
A client transmits only job information of print data to a server, the server manages a print order in accordance with the job information, and if printable, the client transmits the print data directly to a printer. After the print is completed, the printer notifies the server of a print completion, and upon reception of this print completion notice, the server instructs the client to delete the print data. In a print system on a network configured as above, the network traffic is not increased, a large memory capacity is not necessary for the server so that the server load is reduced, the job management of the server can be performed by the client, the completion of a print operation can be monitored, and a print operation is possible even if the server is in an error state.
Abstract:
An optical disk apparatus comprises an optical pickup having an optical pickup body carrying a laser and a photodetector responsive to light emitted from the laser and reflected by the optical disk for producing tracking error signals mounted on the optical pickup body for reciprocal movement in a tracking direction responsive to operation of an actuator, and supports an objective for focusing the beam on the disk. A position sensor produces position signals in response to displacement of the movable portion in the tracking direction. Finally a servo tracking circuit outputs driving signals to the actuator on the basis of tracking error signals produced either in response to tracking error signals produced from outputs of the photodetector and position signals produced from output signals of the position sensor, in response only to the latter. The optical disk apparatus having the foregoing construction eliminates direct-current offset included in tracking error signals, stabilizes driving of the objective, and reduces access time.

An image processing apparatus includes: an image pickup unit that images an image of a face; a first extraction unit that extracts a first image pattern as a correct solution pattern based on a sample image of the race; a second extraction unit that extracts a second image pattern as a counterexample pattern based on the sample image; a learning unit that learns a pattern recognition of the target part based on the first image pattern and the second image pattern; an identification unit that identifies a face area from the image of the face, the face area being an area where the face is shown; and a detection unit that detects a position of the target part from the face area based on the pattern recognition of the target part.
Abstract:
A data processing method is provided whereby, even if communication delay occurs between computer game devices connected through a communication network, data is processed practically simultaneously between the respective computer game devices. When a computer game contest is carried out through a network having communication delay, before the game is started, the delay times between the game devices are found and, using these, synchronization of the time counted by the individual game devices is obtained. Then, during the progress of the game, the operating data signal is processed after the lapse of the longest delay time of the delay times between the game devices measured beforehand after it is generated. In this way, the operating data signal can be processed simultaneously in a plurality of game devices.
Abstract:
A map generation apparatus includes an acquisition unit, a classification unit, a tentative map generation unit and a map generation unit. The acquisition unit acquires information which is a target of an analysis process. The classification unit classifies the acquired information into a plurality of types. The tentative map generation unit selects the types provided by the classifying one by one as a type in question to generate tentative map information of the information belonging to the type in question, based on (i) the information belonging to the type in question and (ii) representative information that represents at least one type other than the type in question. The map generation unit generates a map image based on the tentative map information generated for the respective types.
