Abstract: Disclosed are an ink-jet recording head capable of preventing destruction of a piezoelectric element relatively readily and securely and an ink-jet recording apparatus.

Abstract: If a received signal includes a message signal following the address of the pager concerned, a decoder section decodes the message signal and a control section stores it in a memory section together with a reception time. At this time, the control section judges whether the message signal includes a sender identification code or a consecutive transmission code. If either code exists, the control section stores it in the memory section together with the message. The control section reads message data from the memory section, and a display control section controls a display section to display the message. If the message includes a sender identification code or a continuous transmission code, the control section searches for messages to be displayed together with the current message from among the other messages stored in the memory section, and the display control section controls the display section to display the found messages en bloc.

Abstract: In a case where a desired radio frequency channel is searched over a plurality of radio frequency channels through manual switching, a received data error detection section 12 detects an error rate of radio data, and an electric field detection section 11 detects a field strength. System information comparison section 6 detects a match or mismatch between the system information of the radio frequency channel and the system information of a wireless selective paging receiver. A display section 3 indicates the result of such detection in the form of an at-a-glance list in decreasing order of receiving probability, thereby enabling the user to select a radio frequency channel having a higher degree of reliability. Further, radio frequency channels which will be covered by a receiving area, system information on each of the radio frequency channels, and area information are stored so as to become associated with one another.

Abstract: Group identification codes, names of parties to be sent, and telephone numbers of the pagers of the parties to be sent are stored in groups in memory 3 of a selective pager. At the time of transmission of a message, telephone numbers of a specified group and a message to be sent for the group are selected from the memory. The telephone numbers and the message are alternately sent to a DTMF signal generation section 8, which converts the telephone numbers and the message to DTMF signals. The DTMF signals are then converted into acoustic signals by means of a speaker 9 and are continually transmitted by way of a transmitter of a telephone set. As a result, a group call can be implemented without involving laborious operations, such as transmission of the telephone numbers and the message one by one.

Abstract: A selective calling receiver display unit having a displaying function, which including a photo-detecting section for detecting the quantity of light of an incident light beam, and a display control section for processing the display action of a display section. The display control section controls the on-off operation of the screen display of the display section according to the quantity of light detected by the photo-detecting section, so that the screen display is automatically turned on and off according to the necessity for screen display which is based on the use of the selective calling receiver.

Abstract: A processor extracts a numeral string from a pager message which has been received via a pager antenna and a pager-signal receiving unit, and retrieves a telephone number including that numeral from a built-in telephone directory memory. The retrieved telephone number is displayed on a display unit, making it possible to determine a complete telephone number.

Abstract: An ink jet recording head is provided with a piezoelectric vibrator. The piezoelectric vibrator includes a diaphragm and a piezoelectric active part. The diaphragm includes a pressure generating chamber communicating with a nozzle aperture, at least the upper surface of which acts as a lower electrode. The piezoelectric active part includes a piezoelectric film formed on the surface of the diaphragm and an upper electrode formed on the surface of the piezoelectric film, formed in an area opposite to the pressure generating chamber. A cap member is bonded on one side of the piezoelectric film for sealing a space with a holder to the extent that the motion is secured. The piezoelectric active part is cut off from the outside of the head by sealing dry fluid in the space of the cap member.
