Title: Speaker unit
Inventor: OOTA KAZUO
IPC: H04R7/02
Filed: 1979-09-10
Abstract: PURPOSE:To improve low-frequency-range frequency response characteristics by providing an opening at one part of a speaker cabinet and by filling the opening part with a member which expands and contracts corresponding to the operation of the speaker. CONSTITUTION:In speaker cabinet 2, speaker 3 is fitted and opening part 2a is formed at the upper of the front face of cabinet 2 and then filled with elastic plate 4. As a signal is inputted to speaker unit 1, cone 3a of speaker 3 vibrates forth and back according to the input signal to generate a sound. When cone 3a is to vibrate, the internal air of cabinet 2 is compressed, so that the internal pressure of cabinet 2 will fluctuate. In this case, elastic plate 4 deforms elastically according to fluctuations of the pressure and expands and contracts so that fluctuations of the pressure will be eliminated. Thus, cone 3a vibrates with excellent rising according to the input signal under no limitation of its motion and never causes split vibration in the intermediate and high frequency range. Further, elastic plate 4 swells by expanding to increase the interval volume of cabinet 2 apparently, so that the low frequency will sufficiently expand.

Title: Transmission reception switching system for radio equipment
Inventor: TAKAHASHI NORIO
IPC: H04B1/66
Filed: 1993-04-20
Abstract: PURPOSE:To utilize the frequency effectively, to realize interrupt talking and to reduce power consumption by providing a function of pausing transmission due to the presence of a voice input to the system. CONSTITUTION:When a voice detection section 17 detects it that a transmission voice input does not reach for a predetermined period, a radio equipment being a sender of a synchronizing signal stops the transmission in a range that the synchronization is secured. A radio equipment not sending the synchronizing signal stops the transmission till the voice detection section 17 detects the transmission voice input. Thus, useless radio wave is not sent and interruption is attained and power consumption is reduced.

Abstract: PURPOSE:To cope with size reduction and high resolution by providing plural slits which have irregular intervals or irregular width. CONSTITUTION:This generation device consists of a slit part 32 which have irregular intervals or irregular width slits and is provided on a moving slit plate 1, a slit part 33 on a fixed slit plate 3, photodetectors 30 and 31 for transmitted light from the slit parts, etc. Then the respective photodetectors and slit parts are so arranged that the outputs of the photodetectors 30 and 31 are maximum on the slit plate 1 at a constant interval. Then the quantity of transmitted light at the overlap of the slit parts 32 and 33 is detected 30 and 31, then the quantity of light is much larger than that of a single opening slit, and the SN ratio is improved. Further, the difference between plural photodetector outputs is found, so variation in the quantity of light and variation of a signal due to a nose are canceled and the SN ratio of a necessary peak value is improved. Further, the quantities of transmitted light of the slit parts 3 and 33 have sharp peaks when mutual slit patterns conform with each other and their width corresponds to the slit width. Therefore, a high-accuracy reference signal is obtained as a result of a sharp large peak.
