Title: Speaker system
Inventor: HONDA KAZUKI
IPC: H04R1/28
Filed: 1987-06-17
Abstract: PURPOSE:To improve radiation efficiency in a lowpitched sound range by providing an acoustic tube which is gradually expanded toward an acoustic field space from an empty chamber provided at the rear of a speaker unit and setting a ratio of the aperture area to the throat area of the acoustic tube to 2-6. CONSTITUTION:An empty chamber 8 formed at the rear of a speaker unit 9 and an acoustic tube 5 which is continuously extended from the empty chamber 8 and has the aperture opened to the acoustic field space are provided, and the ratio of the area of the aperture 7 to that of a throat of the acoustic tube 5 is set to 2-6. The radiation resistance of the acoustic tube 5 is raised and the acoustic pressure is increased according as the wave front is gradually extended. Further, since the radiation resistance near the frequency where the half wavelength is put in the acoustic tube is increased and the acoustic pressure in this frequency is increased, the difference of acoustic pressure between the frequency where the quarter wavelength is put in the acoustic tube and the frequency where the half wavelength is put there is reduced. Thus, an efficient and flat acoustic pressurefrequency characteristic is obtained in a band lower than the frequency where the 3/4 wavelength is put in the acoustic tube.

IPC: G05B19/416
Filed: 1990-06-11
Abstract: PURPOSE:To facilitate preparation of a program for processing a hole in a notched plane, by generating such a processing program which feeds a drill quickly up to a notched plane and makes the drill process a hole to a specified depth in accordance with the inputted definition of the notched plane and data for hole processing. CONSTITUTION:When a programmer inputs Z-axis coordinate value Zd, angle 0 degree, hole diameter d and hole depth l, an interactive numerical control device judges whether a notched plane 2 is defined or not, determines a point of intersection P between the notched plane 2 and the center axis of a hole 4, and if the point of intersection P is found, generates a processing program for quickly feeding a drill to the point of intersection P which is defined as the entrance of the hole, then generates a processing program, in which the point of intersection between the raw material plane defined first and the center axis of the hole is taken as the entrance of the hole. Since a program is generated referring to the point of intersection between a notched plane and the center axis of a hole to the entrance of the hole, the depth of the hole can be directly specified. Moreover, since a generated processing program allows quick feed of a drill up to the entrance of a hole, processing program can be made in a short time.

Filed: 1992-06-11
Abstract: PURPOSE:To relax an over load state while it is light by averaging a processing amount without detecting the generation of any abnormality in an opposite side communication system by delaying the response of signals within a range specified by a protocol concerning the transmission/reception of signals for call setting or data transfer. CONSTITUTION:The flow of signal processing from a signal input part 11 to a signal processing part 14 or an interrupting storage processing part 13 is decided based on the overload state judgement of an exchange 10 due to an over load state judging part 12 and when the overload state of the exchange 10 is informed as the inquired result of the overload state judgement due to the input part 11, the signals are stored in the processing part 13 so as to temporarily interrupt the processing. When the signals are stored in the processing part 13, the time of storage is registered on a control part 15 in relation with the signals, and after measurement for fixed time, the control part 15 outputs the signal release instruction of signals to the processing part 13 so as to output the signals from the processing part 13 to the signal processing part 14. When informing that the exchange 10 is not in the overload state from the judging part 12 to the input part 11, the input part 11 directly dispatches signals to the signal processing part 14.

Title: Right-left pincushion distortion corrector for beam index type color television picture receiver
Inventor: MITAMURA ICHIROU
IPC: H04N3/23
Filed: 1978-12-08
Abstract: PURPOSE:To obtain the right-left pincushion distortion correcting signal by giving the clamping to the control signal applied to the voltage control oscillator of the PLL circuit via the blanking pulse for the DC regeneration and the low pass filtering. CONSTITUTION:The index signal is detected 51 from picture tube 10 and then applied to PLL circuit 30, and the gate pulse is generated 53 through oscillator 62 to be supplied to grid 12. On the other hand, the output of low pass filter 64 is clamped 71 with the blanking pulse given through deflecting circuit 30 to obtain the DC regeneration as prescribed. Then the output is made to pass through LPF72 to obtain signal SL showing the shape of the right-left pincushion distortion, and signal SL is amplified 73 to be given to corrector circuit 74. In such constitution, the negative feedback loop is formed based on the free-running oscillation frequency of voltage control oscillator 62 in the PLL circuit, and thus the right-left pincushion distortion can be corrected perfectly to obtain a completely square screen. As the index signal frequency becomes equal to each line, the PLL circuit can be locked assuredly. Thus the beam current which is flowed steadily can be reduced to improve the contrast.
