Title: Detecting system of digital subscriber line fault
Inventor: OCHIAI HIROSHI
IPC: H04L12/02
Filed: 1983-08-22
Abstract: PURPOSE:To distinguish power supply stop of a controller at a terminal device side from a fault generated on a subscriber line by providing a means connecting reflectedly a reception line of a subscriber line to a transmission line when a power supply fed to the terminal side controller is stopped. CONSTITUTION:A data terminal device DTE is connected to the subscriber line SL via the terminal side controller DAU', accommodated in an exchange EX via an exchange side controller DLC and transmits/receives digital information. The terminal side controller DAU' is provided with a reflecting set section LOP and when a power is fed to the terminal side controller DAU', the LOP prolongs a transmission line and a reception line of the subscriber line SL to a data transmission/reception section STR directly. When power to the terminal side controller DAU' is stopped at night or the like, the reflecting set section LOP connects the reception line of the subscriber line SL to the transmission line reflectedly. Thus, the stop of power is not discriminated as an error.

Title: Address converting device
Inventor: KASAI YOSHIO
IPC: G06F12/08
Filed: 1990-06-11
Abstract: PURPOSE:To effectively utilize an idle entry of a translation look-aside buffer TLB by sharing a single TLB for storage of the instruction and operand address conversion pairs. CONSTITUTION:A dual port RAM is used to a TLB 7. Thus the TLB retrieval can be carried out for conversion of instruction addresses independently of and simultaneously with the TLB retrieval for conversion of operand addresses. When the register requests occurs at one time for both conversion pairs of instruction and operand addresses (correspondence between logical and physical addresses), i.e., when both an instruction address register request 22 and an operand address register request 23 are validated at one time, a register control part 8 arbitrates both register requests to first register an operand address conversion pair and then an instruction address conversion pair respectively. Thus an idle entry of the TLB 7 is effectively utilized.

Abstract: PURPOSE:To increase cathodic protection effect and prevent inflation of film of corrosion- proofing coating, which is readily generate in cathodic protection, by a method wherein an electro-conductive metallic pipe is inserted into the end part of the heat exchanging pipe whose inner surface if coated with the film of corrosion-proofing coating to conduct the metallic pipe electrically to the heat exchanging pipe. CONSTITUTION:The conductive metallic insert member 2 is fitted into the inner surface at the tip end side of the heat exchanging pipe 1 coated with the corrosion-proofing film P and a part or the total length of the insert member 2 is conducted electrically to the pipe 1. Accordingly, corrosion-proofing electric current, generated by the electric protection, flows at first through the insert member 2 and flows to the direction of the heat exchanging pipe 1 through the conducting section E. The conductivity of the insert member 2 is much higher than the same of the corrosion-proofing film P, therefore, most of the corrosion-proofing current, flowing through the heat exchanging pipe 1, flows from the insert member 2 to the direction of the pipe 1. As a result, reactions of formulas ( I ), (II) in the diagram which are generated at the boundary surface of coating of the corrosion-proofing coating film P, may be restrained remarkably and the inflation of the coating film P may be prevented as much as possible. The most common insert member 2 is copper, iron, aluminum or alloys containing these metals.

Abstract: PROBLEM TO BE SOLVED: To provide the cell buffer control method for confirming an operation of an ATM(asynchronous transfer mode) cell band warrant function by which whether or not the band warrant function is normally in operation even during operation of connection. SOLUTION: In the case that a storage amount of a cell buffer 101k is smaller than a preset threshold value, a cell storage amount detection section 103k detects to generate a load test cell, which is stored in the cell buffer 101k for the control, and when user cells are received, a load test cell abort control section 102k detects it to apply abort control to the load test cell stored in the cell buffer 101k. Thus, user cells are stored always in the cell buffer 101k in the order of earlier addresses and in the case that the storage amount is smaller than the threshold value, the storage of the cell buffer 101k is controlled by the load test cells at all times, that is, controlled to be in an overload state at all times. Then the warrant band outputted from a scheduler is confirmed during operation without giving effect on user cells.

IPC: G11B15/02
Filed: 1981-09-30
Abstract: PURPOSE:To improve the operability, by providing a means to store several zero positions (head position of each music) of a timer display device, and securing the stoppage of a tape at the stored zero positions from an optional position of the tape. CONSTITUTION:A display device 16 has a zero display with a simultaneous push of both a clear button 17 and a zero location button 19 of a recording start position A. The position of a point A is stored in a memory counter circuit 28. When the reproduction is carried out at the recording end position B, a button 18 or 19 is pushed. The tape is rewound quickly by a circuit 31 and through a digital comparator 32 and stops at the position A. If the button 17 is pushed once to reset the tape at the position A, the tape never returns even with a push of a button 18 or buttons 19-20. When a reproduction button is pushed after the end of the locating action, the automatic location is performed to secure a reproduction mode. For the recording of the 2nd music, the button 17 is pushed at a position C of the head of the music. Thus a memory counter circuit 27 is cleared, and the display of the device 16 is set at zero. Then the circuit 27 stores zero. The button 18 is pushed when set back the tape at the position C is required.

Filed: 1990-06-14
Abstract: PURPOSE:To increase the cooling effect of the coils of a transformer by fixing a duct piece for forming a cooling duct with insulation paper mounted outside the conductor of the coils or on the end portion of the coils, or an insulation cord. CONSTITUTION:A gas duct 5 arranged in a coil is made into only a duct piece 11 by eliminating a duct seat in a portion where heat is generated from the coil. In the portion where heat is not generated, the duct piece 11 is fixed by insulation paper 12, a cord or the like. In the portion of the gas duct 5, an electric current flows through the coil. No duct seat of insulation paper being required in the conductor portion of the coil which generates heat, the gas duct 5 is formed. Since the generated heat from the coil is transmitted directly to gas which is a refrigerant without using insulation paper 12 which is a duct seat, heat conductivity improves, thereby increasing the cooling efficiency.
