Title: Method and apparatus for adjusting frequency response characteristic of signal transmission
Inventor: CHIYAARUSU REONARUDASU KORUNER
IPC: H03G5/16
Filed: 1988-09-14
Abstract: PURPOSE: To adjust, for example, equalize transmission characteristics to two listening positions in a space by making a distance between a first converter and a first listening position smaller than a distance between the first converter and a second listening position. CONSTITUTION: Two listening positions P1 and P2 are positioned almost between two converters 8 and 9, and a distance between the first listening position P1 and the first converter 8 is made smaller than a distance between the second listening position P2 and the first converter 8. On the contrary, a distance between the second listening position P2 and the second converter 9 is made smaller than a distance between the first listening position P1 and the second converter 9. Thus, the frequency response characteristics of filters 16-18 can be changed by control signals S1-S4 , and also the frequency independent gains of those filters can be adjusted by those control signals.

IPC: H04J3/00
Filed: 1987-09-11
Abstract: PURPOSE:To reduce remarkably the write time of setting data from a line setting device by adding a storage means as a buffer memory. CONSTITUTION:Input data is written in a data setting memory 200 via a contact 500 of 1st switch and written in a storage means 710 (buffer memory) via a contact 510 of a 2nd switch. A storage means 710 uses a control signal from a storage control means 750 to read the data written newly by the control signal from the storage control means 750 and writes it in a storage circuit 700. In the start of power supply, the data stored in the storage circuit by the control signal is read and written in a data setting memory 200 via a contact 500 of the 1st switch. The write time from the line setting device is reduced remarkably.

IPC: G11B20/10
Filed: 1986-09-27
Abstract: PURPOSE:To eliminate a need of adjustment of the free-running frequency of a voltage controlled oscillator VCO and read accurate data at the time of normal reproducing as well as searching by controlling the oscillation frequency of the VCO on the basis of the output of an operating means so that this oscillation frequency is equal to the frequency of PLL data. CONSTITUTION:A PLL data area detecting circuit 7 detects a PLL data area in read digitized data, and the frequency component of PLL data is latched by a latch circuit 79, and the oscillation frequency component of a VCO 85 is latched at a prescribed period by a latch circuit 80. The differential component between both latch outputs is calculated by a comparing circuit 82, and the oscillation frequency of the VCO 85 is controlled on the basis of the calculation result so that this oscillation frequency is equal to the frequency of PLL data. Thus, it is unnecessary to adjust the free-running frequency of the VCO 85 to make a device convenient for handling, and accurate data is read at the time of normal reproducing as well as searching.

Abstract: PURPOSE:To stabilize the reproduction of a magnetic head by providing a tension control system to control the tension of a magnetic tape and a shift control system to control the shift quantity of the tape, and specifying the control band frequencies of the shift control system. CONSTITUTION:A command circuit 50 samples the signal of a tracking error detecting circuit 30 and the displacement of the rotary phase of a capstan 5 for a reference phase signal at regular intervals of TS in a scanning period TW of a magnetic head 4a. Further, data D0 to D99 are successively stored into a memory. Next, in a period when the signal is not reproduced, the data D99 to D0 are read, and inputted to a control circuit 60. Therefore, the shift quantity of the tape is displaced with frequencies fP=360/thetaP.Nm as reference frequencies, the frequencies fP are made smaller than the control frequencies of the shift control system, and further smaller than those of the capstan control system. Thus, the tension of the magnetic tape is stabilized, and the magnetic tape can stably reproduce the signal.

Title: Processor for pseudo halftone image
Inventor: SHIMAOKA NOBUMASA
IPC: H04N1/40
Filed: 1986-09-29
Abstract: PURPOSE:To improve the quality of a pseudo halftone image at both highlight and shadow parts by correcting an output binary image based on the perfect white and black levels. CONSTITUTION:A multi valued image signal D0 and a threshold value TH are inputted to terminals T1 and T2 respectively and the value of an error signal is corrected by an error signal correcting circuit 5. If the value of the signal D0 is more approximate to a perfect black level LB than the value TH, the difference between the level LB and the signal D0 is defined as a black-side error EB. While the difference between a perfect white level LW and the signal D0 is defined as a white-side error EW when the value of the signal D0 is more approximate to the level LW than the value TH. The circuit 5 corrects an output binary image based on both levels LB and LW. Thus it is possible to regenerate faithfully both highlight and shadow parts even though the image signal levels of an original are not evenly distributed against the processing range of this processor for pseudo halftone images.

Filed: 1988-09-14
Abstract: PURPOSE:To obtain a large valve opening force by guiding a cylindrical or conical float in the vertical direction to be disposed in a valve chest and installing a lever having a valve element in the valve chest with a gradient of an acute angle to the displacement of the float. CONSTITUTION:A float 11 formed like a cylinder or a cone is guided in the vertical direction and disposed in a valve chest 4. A lever 13 having a valve element 15 for opening and closing a valve opening 9 is installed in the valve chest 4 with a gradient of an acute angle with respect to displacement in the valve opening direction of the float 11. The float 11 is guided by a guide means 6, displaced in the vertical direction with the liquid level in the valve chest 4 and brought into contact with the lever 13. As the lever 13 is inclined at an acute angle, buoyancy or dead load of the float 11 works on the lever as a wedge force to increase the valve opening force. Thus, the inclination of the float will not cause a change of contacting position with the lever so as to keep a large valve opening force.

Abstract: PURPOSE:To calculate the speed of revolutions of engine by generating an ignition signal as a variable period signal, transferring other serial data signal to a 2nd device synchronously with its generated timing and using a received timing as an interruption data. CONSTITUTION:The system is devised such that the serial data is sent by the delay of a prescribed time tau from the generation of an ignition signal to avoid noise at the ignition and when the succeeding ignition signal is not generated even a prescribed time T elapses from the transfer of the serial data synchronously with the ignition signal, the succeeding serial data is sent without awaiting the succeeding ignition signal. Thus, the serial data processing of the variable period signal at the sender side is not required, thereby quantity of the software is reduced.
