Filed: 1993-10-08
Abstract: PURPOSE:To obtain a uniform high impedance characteristic at a frequency band of a video signal by providing an unbalance conversion reception section, an automatic gain control section and a balance transmission section to a repeater provided to a trunk line or a branched line. CONSTITUTION:A reception section 21 of a repeater 20 receives a DC current at a frequency band of a video signal and an audio signal and converts the level into a predetermined voltage level and gives the voltage level to an unbalanced conversion reception part, 22, an automatic gain control section and a balance transmission part 24. The unbalanced conversion reception part 22 blocks the audio signal and the DC current to receive the video signal through balancing and sends the video signal through unbalanced conversion. The automatic gain control part 23 amplifies the video signal obtained at the reception part 22 and obtains a predetermined transmission signal level. The balance transmission part 24 keeps a high output impedance at a frequency band of the audio signal and the DC current and sends the video signal.

Title: Filter
Inventor: YOSHIDA TAKAHARU
IPC: B01D29/74
Filed: 1985-11-12
Abstract: PURPOSE:To prevent the clogging of a filter net caused by the accumulation of dust having low specific gravity in the vicinity of the upper end of a container, by changing the length of the blade, which is provided above an inflow pipe in an up-and-down direction, in the radius direction of the container. CONSTITUTION:The fluid introduced into a container from an inflow pipe 14 flows in a vortex form but a stream directed downwardly is generated in the upper part of the container by the action of a blade 20. Because the length of the blade 20 in the up-and-down direction thereof changes in the radius direction of the container, the fluid quickly falls to either one of the center direction or outer peripheral direction of the container. As a result, the suspended substance in the fluid quickly falls while being carried on the stream of the fluid and is prevented from accumulating at the upper end of the container.

Title: Driving circuit for ultrasonic motor
Inventor: SATO HIROTA
IPC: H02N2/00
Filed: 1989-09-29
Abstract: PURPOSE:To do accurate speed control by compressing the logarithm, making the voltage to be input into a voltage control oscillator correspond to the rotational speed to the frequency of an ultrasonic motor. CONSTITUTION:The relation between the input voltage V of a voltage control oscillator and the rotational speed of an ultrasonic motor (USM) 3 is not linear, but in the region where input voltage V is small, the change rate of the rotational speed to the change of input voltage Vc is large, and in the region where input voltage Vc is large, the change rate is small. A logarithm converting circuit 4 has the reverse properties to this, i.e., in the region where output Vc is small the change rate to the output Vc to input VIN is small, and in the region where the output VC is large the change rate is large. Hereupon, by combining these two properties, the relation between the input voltage VIN of a driving circuit and the rotational speed of USM 3 becomes linear. Accordingly, the change quantity of the rotational speed to the change quantity of the input voltage VIN becomes constant, and accurate control of rotational speed becomes possible.

Title: Plowing depth control device in tractor
Inventor: DOI YOSHINORI
IPC: A01B63/00
Filed: 1988-10-11
Abstract: PURPOSE:To improve the stability of plowing depths by disposing a lengthwise inclination angle sensor on a tractor and changing the sensitivity of a plowing depth control section in proportion to inclination angle rates detected with the inclination angle sensor. CONSTITUTION:An inclination angle sensor 16 is fixed on one side of the rear transmission case 2 of a tractor 1 and the lengthwise inclination angles of the tractor 1 are measured, followed by inputting the measured results into a CPU 15. A control section in the CPU 15 changes the sensitivity of a plowing depth control circuit on the detected results of the inclination angle sensor 16. When vibrational amplitudes are small and the inclination angle rates are low, the control section of the CPU 15 lowers the sensitivity of the plowing depth control device to reduce the lifting speed of a rotary 5, thereby averaging the finishing of a field without causing any hunting phenomenon. When the unevenness of the surface of the field is large, the sampled and averaged vibrational amplitude is large and the averaged inclination angle rate is high. In such the time, the sensitivity of the plowing depth control device is not lowered an the plowing depth control device follows the unevenness of the surface of the field without any retardation of the response of a lift arm 9, thereby preventing the fluctuation of the plowing depth.
