A linear actuator is provided that has a configuration capable of inhibiting contact between an inner core and a plate spring that is connected to the inner core and an outer core, and which is realized by a configuration that is easy to assemble. A stator is arranged in an opening section of a through-hole in the inner core, and has a spacer through which a shaft passes. An outer frame section of the plate spring is connected to the outer core, and a fixed section of the plate spring is connected to the inner core through the spacer in a state in which the shaft passes therethrough. The spacer includes a penetration section having an insertion hole which the shaft is inserted through, and restriction sections and which restrict a displacement of a predetermined amount or more of the plate spring to the inner core side.

In a cellular phone (), text data (code data) corresponding to user's input operation is converted into first data format (BMP format or the like) image data. The image data is synthesized with input image data such as a photograph to be allotted in a given format. The image data arranged and synthesized in the format is converted into image data of a second data format (JPEG, GIF, or the like). The converted image data is then printed on a recording sheet () in a printer ().

A method and system for storing data in a non-volatile memory having a plurality of memory regions each assigned with a serial address to permit serial accessing of the plurality of memory regions. Each memory region has a writing count number storing region and a data storing region. In accessing the non-volatile memory, contents of the writing count number storing regions are checked serially to locate an effective memory region having the last serial address among memory regions having the same writing count number. In writing data into the non-volatile memory, a memory region having an address following that of the located effective memory region will be accessed, and in reading data from the non-volatile memory, the located effective memory region will be accessed. The final address of the non-volatile memory is followed by the first address thereof, thus permitting circular or access to the serially addressed memory regions of the non-volatile memory.

A portable telephone having a first and a second box-like casing part which are foldably connected by a hinge. The first casing part accommodates at least a display and a speaker while the second casing part accommodates at least a microphone. When the two casing parts are folded, a control circuit interrupts power supply to the display, microphone, and speaker.

On determining an entire majority of five i-th received data bits which correspond to an i-th original data bit repeatedly received five times, first through I-th received data bits of a first received frame are stored in a main buffer (41) as first through I-th memorized data bits. A first partial majority is determined as regards two data bits, the i-th memorized data bit and an i-th received data bit of a second received frame. When the two data bits are and are not identical, first and second logic values are stored in an auxiliary buffer (42) as an i-th auxiliary data bit. Second and third partial majorities are successively determined by using the memorized and the auxiliary data bits. Likewise determined, a fourth partial majority gives the entire majority. When an original frame is repeatedly received more than five times, first through (N-1)-th counter buffers are substituted for the auxiliary buffer to memorize first through I-th memorized counts for use together with the memorized data bits in successively determining partial majorities of the type described.

Terminal equipment having transmitting and receiving functions for a vehicle radio telephone system has a function thereof limited to one of a plurality of modes depending on the time zone. The equipment is automatically locked when a predetermined period of time expires after the end of a communication. The area wherein a call can be originated on the equipment is limited to one of local, domestic and international areas on the basis of the time zone. A memory has a plurality of addresses each being loaded with a particular telephone number to allow the single equipment to selectively use a plurality of telephone channels, on the basis of the time zone. A plurality of memories each stores a particular speed call number table or a particular unattended telephone message table, so that the tables are selectively used depending on the time zone. Further, the volume level of an alert tone to be produced on the reception of a call and the illumination for a keyboard and a display are controlled on the basis of the time zone.

A lock control method for on-board terminal equipment of a mobile telecommunications network surely inhibits persons other than the user or an authorized person person from unlocking the equipment with the intention of originating a call thereon. When a unauthorized person enters a lock code resembling a set first lock code, or unlock code, by chance after a great number of lock codes, the first lock code is replaced with a second lock code. Hence, the unauthorized person cannot unlock the equipment despite that the entered code may coincide with the first lock code. While the unauthorized person may further enter other different lock codes, the second lock code serving as the unlock code will be replaced with the first lock code as the entered code approaches the second lock code.

A memory protection circuit is provided which prevents data stored in a programmable memory from being destroyed due to uncontrolled operations or malfunction of a writing unit. The memory protection circuit comprises a first decoder for detecting first predetermined data from write data, a second decoder for detecting second predetermined data out of address data which is associated with the write data, and a latch for latching a detection output of the first decoder when both a detection output of the second decoder and a write command signal exist, and for selectively allowing and inhibiting the write data from being written in a memory based on the information being latched.
