Title: Data transmission system in catv system
Inventor: HASHIMOTO TAKASHI
IPC: H04N7/16
Filed: 1986-01-28
Abstract: PURPOSE:To secure the reliability of data communication even when the performances of system's equipments degrade by superposing a key signal and a data signal on a sound signal at a timing corresponding to the horizontal blanking cycle of a video signal. CONSTITUTION:In a data decoder 2, the key signal and the data signal are superposed on the sound signal corresponding to the horizontal blanking cycle of the video signal by amplitude modulation. In this case, even if a distortion caused by a video source influences the sound signal, since both the key, signal and the data signal are subjected to the same compression-distortion during the said cycle, they are corrected by an AGC amplifier 8. Consequently, a stable detection output is obtained. Therefore, even when the linearity of the CATV system degrades, the reliability of data is not lost.

Abstract: PURPOSE:To prevent the liquid leakage of a cylindrical mercury battery, by inserting a hollow cylindrical positive electrode, which has a taper at the top of its inner periphery, in a cylindrical positive ring, which has an upper horizontal part the periphery of the central hole of which is provided with a piece folded downward. CONSTITUTION:A reversed-U-form positive ring 2 has an upper horizontal part, the periphery of a central hole phi1 of which is provided with a piece 2A folded downward. A hollow cylindrical positive electrode 1, which is molded so that it has a taper 1A at the top of its inner periphery, is inserted in the positive ring 2. After that, the ring 2 containing the positive electrode 1 is placed in a positive case 3, before it is pressed and fixed to the positive case 3. A cylindrical mercury battery is constituted by combining this positive part, a separator 4 and a negative electrode 5. Owing to the above constitution, the deformation and the falling of the upper part of the positive electrode are not caused during when the battery is sealed. Consequently, the deterioration of the performance, which might be caused by internal short-circuits, can be prevented.

Title: Automatic speed changer for vehicle
Inventor: KASHIWARA TADASHI
IPC: F16H15/52
Filed: 1984-02-02
Abstract: PURPOSE:To increase the life of a speed changer, by transferring a driving system from a speed change driving condition through the friction stepless speed changer to a directly-coupled driving condition without through the speed changer when a speed change ring reaches the predetermined position in a high speed side. CONSTITUTION:When a speed change ring 9, providing a cam device comprising cam surfaces 13, 14 and a roller 15 further adapting a pressing device 20 causing the speed change ring 9 to be transferred to a high speed side, reaches the predetermined position in the high speed side, a driving system is transferred to a directly-coupled driving system operated not via a speed changer. In this way, a life of the speed changer can be increased because a time for transmitting power via a speed change driving system is relatively reduced as compared with the total time for running a vehicle so as to reduce also the time for a speed change actuated part of the speed changer in relation to power transmission.

Title: Data transmission method
Inventor: MATSUMOTO MASAHIRO
IPC: H04L5/22
Filed: 1978-02-17
Abstract: PURPOSE:To lessen the load of the terminal and thus to increase the transmission efficiency by requesting the interruption to the remote master communication station via the interruption signal transmission channel every time the communication request is given at the subordinate communication station. CONSTITUTION:Interruption signal transmission channel A and data transmission channel B are set previously between master communication station 30 and the partner subordinate communication stations 31-33. Here, in case the communication request takes place at station 31, IT is transmitted by the interruption signal via channel A to be received at station 30. And if the request can be accepted, interruption reception signal ITR is transmitted via channel A, and at the same time signal SOH indicating the control information for the communication start is transmitted through channel B. Thus, station 31 receives signal SOH and has communication with station 30 via channel B. In this way, the load of the terminal can be lessened, thus increasing the transmission efficiency.
