Title: Transmission system of exchange signal
Inventor: FUKUYAMA HIDEO
IPC: H04L12/437
Filed: 1982-06-29
Abstract: PURPOSE:To prevent malfunction of an exchange connected to each device without losing other transmitting information, by using a spare bit of a time slot for exchange signal transmission for displaying a discriminating code of the device. CONSTITUTION:The exchange signal of an exchange signal transmitter 15 of a device 3 is received with an exchange signal receiver 18 of the device 3 for the same information of a signal transmitted from the device 18 again, when devices 4, 6 perform a reflexing communication between a PCM line 11 being a common use line and a PCM line 12 being a spare line because of any cause such as maintenance or failure of the system. The number of the signal transmitter is given to the exchange signal of each channel by using a spare bit of the time slot for exchange signal transmission. Thus, the exchange signal of the own device transmission is distincted from the exchange signal transmitted from other devices, and when the exchange signal having the same identification code as the own device identification code is received, the receiving signal is disregarded and failure information is transmitted to the exchange instead.

Title: Leader tape for magnetic tape and trailer tape
Inventor: SAKAMOTO KAZUNORI
IPC: C09C1/48
Filed: 1992-05-06
Abstract: PURPOSE:To prevent the shaving and adhesion of a tape guide, and to inhibit a tape squeak by forming coating layers on both surfaces on the magnetic head side and the tape travelling side. CONSTITUTION:Coating layers are formed on both surfaces on the magnetic head side and the tape travelling side. A magnetic layer mainly comprising ferromagnetic powder, abrasives and a bonding resin is used as the coating layer on the magnetic head side, and ferromagnetic powder is contained in 100-300wt.% to the bonding resin. On the other hand, the coating layer on the tape travelling side employs carbon black, abrasives and the bonding resin as main components, and carbon black is contained in 40-170wt.% or less to the bonding resin. Accordingly, since the coating layer on the magnetic head side is made the same as the magnetic layer of a magnetic tape, it is not shaven by a thin-film fixing head, and does not damage the head as an impulse, etc. Since the content of carbon black is 40-170wt.% or less to the bonding resin in the coating layer on the travelling surface side, electric resistance is lowered, and there is no possibility of the adhesion of dust resulting from electric resistance.

Abstract: PURPOSE:To prevent the reflux of drainage from a drainage hose by providing a means for opening a drainage solenoid valve after a prescribed eriod since a vacuum device is stopped. CONSTITUTION:When a lid body 15 is mounted on the compression extractor in the title, a drainage solenoid valve 44 is closed, and a vacuum device 38 is operated, air within a pressure reducing chamber 34 is exhausted so that pressure within the pressure reducing chamber 34 becomes negative. Then a pressure plate 33 is raised up to compress kitchen garbage and the like in a garbage bag 9 between a piston 40 and the lid body 15, so that the kitchen garbage is dehydrogated. When the vacuum device 38 is stopped, air goes into the pressure reducing chamber 34 so that the pressure in the pressure reducing chamber 34 is increased to lower the pressure plate 33. And the drainage solenoid valve 44 is opened after a prescribed period required for making the pressure in the pressure reducing chamber 34 approximately equal to an atmospheric pressure since the vacuum device 38 is stopped. Thus, the reflux of drainage from a drainage hose 45 can be prevented.
