Abstract:
The present invention relates to an ultrasonic probe provided with a piezoelectric element for ultrasonic generation that has drive electrodes formed on two main surfaces thereof; an acoustic matching layer formed on the first main surface side of the piezoelectric element; a backing member attached to the second main surface side of the piezoelectric element; a base for heat dissipation provided on a lower surface of the backing member; and a thin metal plate for heat transfer that is thermally bonded between at least one of the main surfaces of the piezoelectric element and the base for heat dissipation; wherein the thin metal plate for heat transfer is surface-bonded to extend from one end of the piezoelectric element over the center thereof toward the other end. This configuration ensures that heat generated by the electrical-mechanical conversion of the piezoelectric element is transferred away in a satisfactory manner, enabling suppression of any temperature rise in the piezoelectric element.
Abstract:
The invention relates to an ultrasonic probe in which the array accuracy of lead wires, and heat resistance when connecting to a connector are enhanced, and a manufacturing method therefor. The ultrasonic probe of the invention is one in which a plurality of piezoelectric elements are arrayed in a two-dimensional direction on a fixing base, and lead wires from the lower surface of each of the piezoelectric elements are inserted through the fixing base, and the electrically connected lead wires are led out, and the fixing base has an opening portion in an array direction of the piezoelectric elements, and comprises unit fixing plates laminated in the array direction, and grooves through which the lead wires are inserted, are formed on one principal surface of the unit fixing plates, and damper material is filled into the opening portion. The invention is also for a manufacturing method for the ultrasonic probe.

Abstract:
A method of controlling data sending and receiving operations between two microprocessors, in which a second controlled-side microprocessor receives a selected signal which is one of a data sending request signal and a data receiving request signal from a first controlling-side microprocessor and the second microprocessor also receives a resultant select signal produced by a logical OR operation on both request signals and determines if the selected signal indicates a "receiving request" or a "sending request" at the same time that it responds to the resultant select signal, thereby executing the requested operation. Hence, even if the second microprocessor does not receive the resultant select signal and the sending/receiving signal at the same time, the second microprocessor can determine simultaneously with the receipt of the resultant select signal if it should send or receive the data, resulting in high-speed data processing.
Abstract:
A dot print head comprising a yoke, a plurality of cores formed integrally with the yoke in an annular arrangement in the peripheral portion of the yoke, solenoid coils wound respectively around the cores, armatures fixedly provided respectively with styluses, an armature support supporting each armature at the middle portion thereof opposite to the corresponding core for swing motion, and an armature holding member disposed opposite to the yoke with a predetermined gap therebetween to hold the armatures on the armature support for swing motion. A plurality of joining parts are formed on the yoke on a line on which the cores are arranged, and a plurality of joining parts are formed on the armature holding member so as to be joined respectively to the connecting parts of the yoke in joining together the yoke and the armature holding member.

Abstract:
Weight data of articles for sale is stored and a total weight is calculated every order. Measured weight of the prepared articles in a package is compared with the calculated total weight. If the measured weight substantially disagrees with the calculated total weight, error information is provided to the operator to correctly package the articles. Comparison may be effected every order number. An addition flag may be further stored with weight data every article to indicate that the article is a target of weight measuring. A non-addition key indicating that the corresponding article is not packaged may be further provided. When the non-addition key is depressed, the weight of the corresponding article is not included in the total weight. The total weight may be printed on the receipt, so that the operator can compare the printed total weight with the measured weight. The total weight may be printed with bar codes. A balance has a bar code reader for comparison. The bar code reader may be provided to the electronic cash register. A controller communicating with the electronic cash register may be further provided at a kitchen for comparison. The order number may be printed on a receipt read by a bar code reader. The controller has a monitor display for informing the error. The difference in weight may be further displayed.
Abstract:
A digital data recording and reproducing system comprises a data input part and a data output part. Input data is manipulated through a computer system unit. The computer system unit comprises at least one of: a data retention part to store the digital data, a personal identification part to verify whether a user operating the digital data recording and reproducing system is authorized or not, an access log recording part to record that the user has accessed the data retention part, a falsification detection part to detect whether data stored in the data retention part is falsified or not, and a history data recording part to record information on changes or corrections in the data retention part. The computer system unit further comprises a control part which controls parts by giving operation instructions to the parts which the computer system unit comprises as the component parts, the parts including at least one of the data retention part, the personal identification part, the access log recording part, the falsification detection part, the history data recording part, the attribute control part and an execution decision part.
