Title: Receiver
Inventor: MIWA KENJI
IPC: H04H60/37
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption when a power source is in OFF in an FM multiplex broadcasting receiver. SOLUTION: An intermittent reception operation is executed when the power source is OFF. To put it concretely, BIC and service discrimination information included in packet data are intermittently received in a step S1. When the service discrimination information indicates program index data (YES in S2), the packet data are received and error correction is executed (S3). When it is judged that the data for which the error correction is performed are the data for indicating emergency information as a result (YES in S4), a continuous reception processing is performed. By the intermittent reception operation, the power consumption is reduced in comparison with the case of performing continuous reception.

Title: Horizontal synchronous pulse generation circuit
Inventor: TAKEYA NOBUO
IPC: H04N5/06
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To reduce peripheral parts without changing relative time between a horizontal pulse edge and a vertical pulse edge even if a horizontal screen position is changed by generating a horizontal trigger pulse and a vertical trigger pulse with the same clock. SOLUTION: A video signal is inputted to a synchronous separation circuit 107. A horizontal synchronous pulse is outputted to a reference clock generation circuit 101 and a vertical synchronous pulse to a latch circuit 106. A counter circuit 102 sets a pulse which is outputted from the reference clock generation circuit 101 and which is 32 times as the reference clock of a counter and uses the vertical pulse outputted from the latch circuit 106 as a reset trigger pulse. A horizontal pulse generation circuit generates a pulse having a horizontal period and a vertical pulse generation circuit 104 a pulse having a vertical period by using the pulse outputted from the counter circuit 102. Thus, a microcomputer 105 is prevented from malfunctioning and a complicated pulse generation circuit is not necessary.

Abstract: PURPOSE:To provide an electron emitting electrode with its drive voltage stabilized, provide a fluorescent panel incorporating the electrode, and establish a method of manufacturing the fluorescent panel. CONSTITUTION:A fluorescent panel 10 includes an enclosed chamber 13 bounded by an upper glass plate 11 and a lower glass plate 12, and a pair of electron emitting electrodes 1 are arranged in this chamber 13.

Abstract: PROBLEM TO BE SOLVED: To increase the sound pressure by making a sound holes to a case so as to have a larger diameter gradually toward outer side thereby resonating a sound emitted from a speaker effectively. SOLUTION: Two sounding holes 27, 28 that are penetrated in the broadwise direction of a frame 17 are made to the frame 17 in the inside of a case 16 corresponding to a disposed position a speaker 25. The sound holes 27, 28 are formed to have a larger diameter gradually toward the outer side of the frame 17 as a truncated cone shape to the case 2. The sound holes 27, 28 are made symmetrically with a reinforcement wall 29 in between and the sound holes 27, 28 have three slopes and a vertical side face formed by the reinforcement wall 29. Since sound holes 27, 28 are increased in their diameter toward the outer side of the case 16 gradually, the sound from a sound port 24 of the speaker 25 is propagated without being disturbed by the sound holes 27, 28 to obtain an effective resonance effect.  Or one sound hole may be adopted and the shape is not limited to be the truncated cone but a circular or an elliptic shape is adopted when the shape is gradually increased toward the outside of the case.
