Patent number: 5463368Abstract: In order to change a subscriber alert mode of a radio pager from an audible alert mode to an inaudible alert mode, a normally open function switch is depressed while the radio pager operates in the audible alert mode. The function switch is subsequently depressed. Following this, a timer is set to count up to a predetermined time period. A pager display exhibits a silent time duration for which the pager will operate in the inaudible alert mode if the timer counts up the predetermined time period. Subsequently, another timer is set to count up to a predetermined time period if the function switch is released. Thereafter, if the second timer counts up the second predetermined time period and if the function switch remains released, the radio pager is set to operate in the inaudible alert mode for the set silent time duration.Type: GrantFiled: December 7, 1993Date of Patent: October 31, 1995Assignees: NEC Corporation, NTT Mobile Communication Network, Inc.Inventors: Kazuyuki Tsunoda, Ichiro Fujisawa

Patent number: 5369799Abstract: A radio pager has a variable gain adjustable to high setting for normal reception or low setting at which the strength of intermodulation products is reduced in relation to the strength of a desired signal. A sync code contained in a received signal is detected to establish synchronization and a sync-absence signal is generated if it is not detected during a time interval in which it is expected to occur. The pager is initially switched to the high gain setting. In response to a first generation of the sync-absence signal, the pager recognizes that the desired signal is severely affected by intermodulation products and switches to the low gain setting so that the signal-to-noise ratio of the desired signal is improved. In response to a second generation of the sync-absence signal, the pager recognizes that its amplification gain is not sufficient and switches to the high gain setting to resume normal reception.Type: GrantFiled: June 25, 1992Date of Patent: November 29, 1994Assignee: Nec CorporationInventor: Kazuyuki Tsunoda

Patent number: 5274369Abstract: A radio paging receiver having a primary power source, and outputs boosted by DC--DC converters as its secondary power sources. The radio paging receiver is provided with a first DC--DC converter which operates all the time or while the power source is on and a second DC--DC converter which operates intermittently to be active only when the load current is greater. The first DC--DC converter is so set as to be higher in source efficiency under light load and the second, as to normally operate even under heavy load. The first DC--DC converter supplies power to the circuits including a decoder in all the modes including the standby mode and the battery saving mode, both imposing only a light load. The second DC--DC converter intermittently operates to be active only in the heavy-load message data processing and message display modes, and supplies power to a CPU and an LCD signal processor in these modes.Type: GrantFiled: March 18, 1991Date of Patent: December 28, 1993Assignee: NEC CorporationInventors: Kazuyuki Tsunoda, Kuniaki Kohga

Patent number: 5221923Abstract: In a radio communication apparatus for selectively receiving call signals indicative of call numbers, respectively, a decoder receives, in cooperation with a P-ROM, each of the call signals as a received signal and processes the received signal into a common call tone signal representative of reception of the received signal regardless of the call numbers. The decoder makes a tone generator generate a common tone in response to the common call tone signal to indicate arrival of reception of one of the call signals. When a manual operable switch is operated, the decoder makes the tone generator stop generation of the common tone and classify the received signal into one of individual tone signals corresponding to the respective call numbers. Subsequently, the decoder makes the tone generator generate a particular tone indicating the call number of the received signal in question. When the switch is again operated, the decoder makes the tone generator stop generation of the particular tone.Type: GrantFiled: November 19, 1991Date of Patent: June 22, 1993Assignee: NEC CorporationInventors: Kazuyuki Tsunoda, Masahiro Matai

Patent number: 5077829Abstract: In a radio communication apparatus in which an audible tone is generated (21-22) in response to reception (15-17, 19) of either a primary or a secondary call signal and stopped by a reset switch (23), the audible tone is stopped (172, 18) when the secondary call signal is received. When the primary call signal is received, the audible tone is not stopped unless the reset switch is continuously closed during a predetermined time interval. Alternatively, the audible tone is stopped when the reset switch is twice closed although the audible tone is produced again after the audible tone is stopped when the reset switch is once closed. As a further alternative, the audible tone is stopped in response to repeated closure of the reset switch without being again produced when the reset switch is once closed.Type: GrantFiled: July 13, 1990Date of Patent: December 31, 1991Assignee: NEC CorporationInventors: Kazuyuki Tsunoda, Kazumori Yamada

Patent number: 4935745Abstract: A slot antenna is integrated with and forms part of the housing for a miniature radio receiver having dimensions comparable to the dimensions of a credit card. The antenna is formed by three plates arranged to have a generally U-shaped cross section. One plate is on one side of and is approximately the dimensions of the "credit card" receiver. A second plate is much more narrow and extends along one edge of the other side of the "credit card" receiver in a spaced parallel relationship with the first plate. The third plate extends vertically between the first two plates and along the one edge of the "credit card" receiver. Together, the three plates make up not only the antenna, but also three sides of the housing of the receiver.Type: GrantFiled: June 6, 1989Date of Patent: June 19, 1990Assignee: NEC CorporationInventors: Toshihiro Mori, Kazuyuki Tsunoda, Masayoshi Yamashita

Patent number: 4660032Abstract: A radio paging receiver comprises a linear array of display elements, a memory having a plurality of storage locations for storing a received message code therein, and a microprocessor-based decoder. The microprocessor-based decoder is responsive to a received preamble code for detecting a match between an address code and a user's own code to store a message codeword into the memory in response to the detection of the match. A first sequence of characters is read from predetermined storage locations of the memory and fed to the display elements. In succession, a blank which immediately follows the first sequence is detected to read a second sequence of characters from the positions immediately following the detected blank and displayed by clearing the characters of the first sequence.Type: GrantFiled: August 14, 1986Date of Patent: April 21, 1987Assignee: NEC CorporationInventor: Kazuyuki Tsunoda
