Abstract: PURPOSE:To save labor, to make a device compact and to improve economy and reliability by controlling a phase converting means from a distant place where a maintenance person is resident. CONSTITUTION:Based on a command to be inputted from the remote place, a phase converting means 400 converts a phase in a first time division highway 300 for each signal to be transmitted on each subscriber line 2 and a phase in a second time division highway 500 for each signal to be inputted/outputted to a time division exchange 1 mutually. In such a way, the phase converting means 400 is controlled from the remote place where the maintenance person is resident. Accordingly, the respective subscriber lines can be housed in the arbitrary phase on the second time division highway 500, namely, housed in the arbitrary housing position of the time division exchange. Each subscriber circuit, a multiple separating means and the phase converting means can be made compact and economic by digital technique and can be operated semiparmanently without elements to accompany wearing such as a relay contact. Thus, the labor can be saved, the device can be made compact and the economy and the reliability can be improved.

Abstract: PURPOSE:To prevent undesired interference between a diaphragm back pressure and an edge back pressure and to reduce the disturbance of a frequency characteristic by forming a path linking an edge space at the rear side of an edge to an outer space not through an in-yoke cavity formed in the inside of a magnetic circuit. CONSTITUTION:An edge space 40 is formed to a rear face side of an edge part 34 and the space 40 is linked to a back cavity 52 from an outer plate air vent hole 54 formed between an outer plate 16 and a retainer plate 38 through a slot 14a of an outer circumference of a yoke 14 not through an in- yoke cavity 32. Thus, a sound pressure change in the edge space 40 attended with the movement of the edge 34 is escaped directly not through the cavity 32 in the yoke formed in the inside of magnetic circuits 10,12,14,16 and the sound pressure in the edge space 40 is effectively escaped to the outer space 52 effectively. Thus, undesired interference between the sound pressure change in the in-diaphragm space 31 and the sound pressure change in the edge space 40 is prevented and the disturbance of the high frequency characteristic is not caused.

IPC: G03B17/14
Filed: 1986-11-14
Abstract: PURPOSE:To shorten the working time by cutting the surface including a surface having a fine hole after fixing the first and second mount members and execut ing dimension setting and then allowing oil to be introduced into the fine hole on the mount member. CONSTITUTION:As for a mount ring 1 which is press-worked, a fine hole 15 is formed at the slidable part between an opponent mount through the laser or electron beam method. After the cutting work, the hole is allowed to contain lubricating oil, and the superior mounting durability is provided. The lubricating oil oozes out to the mount surface by the acceleration of the capillary tube phenomenon by the generation of local heat or the negative pressure suction action through the mounting/demounting sliding of the mount.

IPC: G09G5/00
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the situation in which unnecessary accesses are conducted to a video memory and a display buffer because image data, that are overwritten by an attribute having a higher display priority and are not displayed, are read from the video memory and being written into the display buffer. SOLUTION: The device is provided with an attribute converting circuit and a source address computing circuit. When display regions of attribute data on a prescribed horizontal one line of a display screen are overlapped, the pixels of an attribute having a lower display priority are disappeared and the display regions on the screen are changed by the disappeared pixels, the changed display regions are made into new display regions by the attribute conversion circuit. If divided, the attribute data are converted into attributes having the number of divisions in which divided display regions are made into new display regions by the attribute converting. The source address computing circuit computes addresses of a video memory, in which corresponding source image data exist, from new display regions converted by the attribute converting circuit.  Note that the operation, in which data in the video memory are written into a display buffer for every horizontal display line, is repeatedly conducted.

Title: Measuring instrument for characteristics of power line conductor
Inventor: UIRIAMU REIDO SUMISU BUANIZU
IPC: G01R23/16
Filed: 1987-10-28
Abstract: Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system. Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state. Direct local control may also be effected, for example, the prevention of overloading a transformer. A <<donut>> state estimator module comprises a novel hot stick operated hinge clamp and a novel voltage sensor which measures the current between an isolated capacitor plate and ground. The donut measures the fourier components of voltage and current over a number of cycles and transmites the components to the local receiver. The local receiver derives the desired electrical measurements such as voltage, current, power factor, power, and reactive power and transmits them to local or remote control stations. Up to 15 donut modules may transmit on a single channel to a single local receiver. Each transmits at intervals which are an integral number. The intervals between transmissions of all donuts do not have a common factor and the average interval is the desired transmission rate. Each donut uses the zero crossover of current of its conductor to establish its transmission interval. The system is self-calibrating using known reference signals within the donut module.
