Title: Controlling device for electric vehicle
Inventor: ROKUTAN HIDEAKI
IPC: H02P7/28
Filed: 1980-09-05
Abstract: PURPOSE: To improve the travelling performance of the subjected vehicle by a  method wherein the value of accelerating command current, to be used when starting and plugging, is adjusted separately in proportion to the current continuity rate  of a chopper.  
     CONSTITUTION: With an accelerator 17 fully opened when the vehicle is starting, the output of operational amplifiers OP1 and OP2 is turned to L level if the current continuity rate of a chopper circuit 14 is small and the output voltage of the accelerator rises quickly. Besides, when the current continuity rate is increased, the output of the operational amplifiers OP1 and OP2 is turned to L level and the accelerator output voltage is maintained at the voltage of Zener diode ZD1. Then, when the transistor TR3 becomes non-conductive, the accelerator output voltage attains the maximum level. When plugging is performed with the accelerator fully opened, the output voltage of the accelerator drops to the level of the voltage of the Zener diode ZD2, because it has a small current continuity rate. If the current continuity rate is increased, the accelerator output voltage is temprarily dropped and then it is controlled at the same characteristics at it was at starting.

Title: Detection method of optimum recording bias for magnetic recording and reproducing unit
Inventor: INOMATA AKIRA
IPC: G11B5/027
Filed: 1978-10-04
Abstract: PURPOSE: To automatically detect the optimum recording bias by sweeping the recording bias through the recording level set to a given level.  
     CONSTITUTION: After setting the recording bias to the standard level, the recording bias is sequentially changed between the upper and lower limits to sweep and the end signal is produced at the end. Further, the reproducing level corresponding to each of the recording bias is stored in the RAM 21. Further, in response to the end signal, the computer 20 performs discrimination and operational processing by using the reproducting signal level stored to detect the maximum value M. Further, the number of times in which the reproducing signal level is equal to the value M is detected and if the number of times is more than a given number, e.g., 3, the discrimination signal is produced. Next, in response to this discrimination signal, the recording bias corresponding to the first reproducing signal among the number of times of production, is taken as the optimum recording bias. Thus, the optimum bias can automatically be detected.

Filed: 1984-06-15
Abstract: PURPOSE:To prevent deterioration of a tone quality, by constituting a howling suppressing device in such a way that, when howling occurs at an intermediate band frequency, the gain of the band is lowered by a necessary sufficient quantity. CONSTITUTION:The output of a microphone amplifier 22 is supplied to an LPF23, BPF24, and HPF25 and the echo signal contained in the low frequency component of the output of the LPF23 is removed in the same way as conventional ones by means of a subtractor section 26, transmitting characteristic estimating section 27, and echo signal estimating section 29. On the other hand, the high frequency componet of the HPF25 is added to the low frequency component from which the echo signal is removed, at an adder section 31 as usual. The intermediate frequency conponent is fetched by the BPF24 and added to the low frequency component and high frequency component at the adder section 31 after the intermediate frequency component is attenuated by a prescribed quantity by means of an attenuating section 30. Occurrence of howling is prevented in a sound field of a long reverberation time, by setting the above-mentioned attenuating quantity to an appropriate value. In this case, deterioration of the tone quality can be prevented, because the band to be attenuated is narrow.
