Title: Graphic equalizer device
Inventor: ADACHI HIROO
IPC: G09G3/20
Filed: 1988-03-17
Abstract: PURPOSE:To prevent a sense of incongruity from being generated in a sound volume variation by constituting the title device so that in case of increasing only a specific frequency band exceeding a reference, a level of other frequency band is lowered automatically and relatively, and also, an output level of the whole is raised automatically. CONSTITUTION:When a command is given so that levels of plural bands which have been divided into each band ascend and descend exceeding the upper limit or the lower limit, respectively, each equalizer and its display level except its band are rewritten to data which descend and ascend at every one step, respectively and operate so as to drive a frequency equalizer and a display device. Also, in this case, volume data is also rewritten to data to be ascend and descend, and the volume of the whole is adjusted. Accordingly, the frequency characteristic can be adjusted extending over a wide range. In such a way, the level quantity which has been varied by the equalizer device is compensated automatically by a volume device, therefore, a sense of incongruity is not generated in a sound volume variation.

Title: Closed angle measuring circuit of igniter for internal- combustion engine
Inventor: SHIMIZU TOSHIO
IPC: F02P17/10
Filed: 1982-04-15
Abstract: PURPOSE:To make a closed angle measurable in a highly accurate manner, by detecting the ON-OFF point and induced voltage from the oscillating waveform of an ignition switching circuit by a comparator, while measuring the closed angle with a monostable trigger circuit, a counter and a storage indicator in combination. CONSTITUTION:The output of a switching circuit 1d is attenuated by an attenuator 2, compared with on-point threshold voltate by a comparator 3, further compared with off-point threshold voltage by a comparator 4, and then monostable trigger circuits 5 and 6 are triggered by each signal respectively. And, the latch signal of the circuit 6 is outputted to an output terminal by the pulse of an angle pulse generator 9 and an AND circuit 113, and a counter 7 is stopped while the calculation is stored in a storage indication circuit 8 by the latch signal passing through a delay circuit 10. Therefore, the output of the monostable trigger circuit 5 is generated at both an induced voltage generating point and an on-point but the clear signal output of a NAND circuit 112 becomes operative at only the on-point adjacent to an off-point, so that the counter 7 starts counting after being cleared at the on-point, then gets stopped at the off-point and the storage is indicated. Thus a closed angle can be measured in a highly accurate manner.

Title: Picture transmission system
Inventor: SATAKE TEI
IPC: H04N19/50
Filed: 1989-03-15
Abstract: PURPOSE:To reduce the occurrence of distortion in a reproduced picture by setting a prediction coefficient to a larger value when the state of a transmission line is excellent and decreasing the prediction coefficient to a smaller value when the state of the transmission line is bad so as to reduce the compression efficiency somewhat. CONSTITUTION:An extrapolation prediction means 9 uses a prediction coefficient selected by a prediction coefficient selection means 10 to obtain a prediction picture signal string from a reproduced picture. The selection of a prediction coefficient depends on the state of the transmission line, and when a transmission state detection means 11 expects it that the detected state of the transmission line is wrong and the occurrence of a transmission error is possible, the prediction coefficient is selected to be 3/8, and in other case, the prediction coefficient is selected to be 1/2. Since the prediction coefficient is selected large when the state of the transmission line is excellent, the coding efficiency is excellent and when the state of the transmission line is deteriorated and a transmission error takes place, the prediction coefficient is selected to be small to increase the redundancy and the effect of distortion is restricted to a near distance thereby reducing the production of the distortion in the reproduced picture at the receiver side.
