Title: Radio data transmission system
Inventor: UCHIDA HIROBUMI
IPC: H04B7/26
Filed: 1988-03-28
Abstract: PURPOSE:To reduce crosstalk due to intermodulation distortion by bringing a frame synchronizing signal into a signal comprising a specific pattern of '1' and '0' for each channel in a radio system applying radio communication of plural channels between plural base stations and plural slave stations. CONSTITUTION:A base station A1 detects a frame synchronizing signal by only the decision of a common code 3 of the frame synchronizing signal in a call signal from a slave station B1 and receives a succeeding data. After the reception of a data in the call signal, the base station A1 outputs a transmission signal and a specific code 4 of the frame synchronizing signal in the transmission signal is an optional code. The slave station B1 detects the frame synchronizing signal from the base station A1 in response to the specific code. When semi-duplex communication is started between the base station A1 and the slave station B1, the specific code of the frame synchronizing signal of the transmission signal from the slave station B1 is replaced into a base station ID code or a channel code. The base station A1 might receive the transmission data from a slave station B2 and an intermodulation wave, but since the frame synchronizing signal differs, the base station a1 does not take the transmission data from the slave station B2.

Title: Ultrasonic wave type flow meter
Inventor: UESUGI NOBUO
IPC: G01S11/00
Filed: 1979-06-14
Abstract: PURPOSE:To provide an ultrasonic wave type flow meter free from measurement errors due to electric and mechanical noise by passing only signals having duration time between electrical and mechanical noise, from signals received. CONSTITUTION:Ultrasonic wave transmitter and receiver 3, 4 are installed on piping through which fuild 13 flows. Trigger pulses from a clock generator 1 are used to oscillate a high-frequency burst wave generator 2 so that ultrasonic pulses are emitted from the transmitter 3. The transmitted pulses are shaped into the desired waveform by passing the receiver 4, a gate amplifier circuit 5, an envelope detector 6, and a discrminator 8. By the difference from pulses from the clock generator 1, the transmission time is measured, so that the flow meter 10 indicates the flow rate. A waveform parameter setting circuit 11 is used to control the high-frequency burst wave generator to have an intermediate duration time between electrical and mechanical noise. Thus, a waveform discriminator circuit 7 can pass signals of the duration time mentioned above so as to remove measurement errors due to noise.

Abstract: PURPOSE:To improve a response to a variation in characteristic so as to simplify the arrangement and control of a control system by providing such an arrangement that a pair of transmission members are moved by counter screws in direction reverse to each other in association with rotation of a motor, and the overlapping margins between resistance members in working chambers are increased or decreased simultaneously. CONSTITUTION:When a manipulating member 51 is rotated by a motor, rotary members 15, 17 are moved simultaneously in opposite directions, as indicated by the arrows, by means a clockwise screw 53 and a counterclockwise screw 55, and accordingly, the overlapping margins L between clutch cylinders 47, 49 in working chambers 39, 41 are increased and decreased simultaneously at the right and left sides. Further, when the overlapping margins L increases, the shearing resistance of silicone oil increases so that the differential motion limiting function and the transmission torque are increased. Meanwhile when the overlapping margins L decreases, the sharing resistance of the silicone oil is decreased so that the differential motion limiting function and the transmission torque are decreased. With this arrangement, since the control may be made within one system, the control system has an extremely simple structure and is miniaturized, and further, since the left and right rotary members 15, 17 are moved simultaneously in association with a manipulation by a control system in the one system, the control thereof may be also simple.

IPC: G11B15/32
Filed: 1981-05-19
Abstract: PURPOSE:To run a tape excellently by providing a locking mechanism for holding a reel on a reel turntable tightly after the reel is mounted on the reel turntable. CONSTITUTION:When a spacer 10 and the recessed part 8' of a cam plate are brought into contact by an elastic ring 12 provided to a reel turntable 3, the shaft 15 of a plunger 14 is projected to the cam plate 8 rotated by the rotation of the reel turntable 3, and then the shaft 15 is inserted into a hole 13 during the rotation of the cam plate 8, which stops the rotation, so that only the reel turntable 3 is rotated. Therefore, a spacer 10 comes into contact with the projection part 8'' from the recessed part 8' of the cam plate 8, and consequently the projection part 8'' presses spacers 10 and 11 out to spread the elastic ring 12. Then, the mean radius of the elastic ring 12 becomes greater than that when a supply reel 6 is mounted on the reel turntable 3, and the reel 6 is held tightly on the reel turntable 3 through the ring 12.
