Abstract: A method of transferring data in one access cycle between two devices over a communications bus. Data is read from a predetermined location in the first device. The data is also latched into a temporary register. Data is simultaneously written into a predetermined location of a second device. The read operation of the first device is terminated and the data from the temporary register is applied to the second device simultaneously with the termination step so that data is available to the second device notwithstanding the fact that the first device has ceased transmission.

Abstract: A line powered telephone interface circuit answers an incoming call and, responsive to a command tone, routes the call to a selected terminal. If no command tone is received within a predetermined time period, low voltage audio signalling devices located near the conventional telephone sets are activated to alert the subscriber of an incoming call. The interface need not be connected to a separated supply source. The device is connected to a telephone line and to at least one plug connectable with a telephone set jack, the device being connected to various terminals. A detector detects the ring signal and a relay establishes connection with a telephone line as soon as the ring signal has been detected for a determined time duration. A combination timer/switcher circuit inhibits the ringing of the corresponding telephone set, and is associated with a sound transducer connected operable by a low voltage signal.

Abstract: The transplantation of donor tissue into the brain is effected by locking the head relative to a stereotaxic unit; penetrating the brain with a first cannula to a predetermined depth to create a transplant site within the brain while the first cannula is fixed by the stereotaxic unit relative to the brain; then feeding a second cannula, which contains donor tissue at its distal end, through the already fixed first cannula so that the distal end of the second cannula comes to rest at the transplant site; and finally withdrawing the first cannula and the second cannula so as to leave the donor tissue at the transplant site.

Abstract: Multilayered ceramic substrates having Cu electrode patterns in or on ceramic-glass insulating layers which consist essentially of Al.sub.2 O.sub.3, SiO.sub.2, B.sub.2 O.sub.3, Na.sub.2 O, K.sub.2 O, CaO, MgO and PbO. The methods for manufacturing the substrate comprises thermally treating a laminate of alternately superimposing ceramic-glass insulating layers and CuO-based electrode layers of desired patterns in air or in a molecular oxygen-containing atmosphere to eliminate organic binders from the laminates by burning out, reducing the CuO into metallic Cu at low temperatures in an atmosphere containing hydrogen, and firing the thus reduced laminate in an inert gas such as nitrogen. The firing is effected at 850.degree. to 950.degree. C. The multilayered ceramic substrate may also be obtained by forming ceramic-glass insulating layers and CuO-based electrode layers alternately on a sintered ceramic support, followed by the thermal treatment, reduction and firing set forth above.

Abstract: The invention provides a surface unit, to be mounted on the surface of a peripheral wall of a tennis court field having a plurality of tennis courts without partition between one court and the other, to prevent a tennis ball that impacts onto the wall rearward of the back line from rebounding into an adjacent court. The tennis ball thus rebounds with a reduced velocity, back to the original court where a game is going on. The surface unit comprises a plurality of repelling members of rebound-reducing material each formed into elongated triangular-sectioned elements, preferably of isosceles cross-section, the plurality of repelling members being installed in parallel on a surface of a peripheral wall of a tennis court field so that the longitudinal direction of each repelling member extends vertically. The flat sides of the members, opposed to ridge lines formed by joining the other two sides of the repelling member, are held at the surface of the peripheral wall either directly or through a sheet member.

Abstract: In a semiconductor memory device having an error correcting circuit, a pair of bit lines and inverted bit lines are connected to the inputs of first and second inverting amplitude circuits through a first and second N channel MOS transistors, respectively, and the output of the first inverting amplitude circuit is connected to the bit line through a third transistor and the output of the second inverting amplitude circuit is connected to the inverted bit line through a fourth transistor. When an error of information of any bit line pair is detected by an error detecting circuit, the first and second N channel MOS transistors are turned off and each bit line pair is separated from the input of the first and second inverting amplitude circuits and, as a result, information of a bit line pair is rewritten by the output of the first and second inverting amplitude circuits.

When a normal power supply potential is applied to the power supply terminal (16), two P channel MOSFET's (1, 2) or two N channel MOSFET's (3, 4) are turned on in response to the input signal.

Abstract: A protecting structure for a harness arranged over stationary and movable sides of a telescopic steering column comprises a flat, wide harness protector for protecting the harness. The harness protector includes a pair of openings opposing each other in its longitudinal direction to introduce the harness thereinto or to extract the harness therefrom.

Abstract: A charge latent image is formed on a recording medium in response to information and a reference pattern so that the information and the reference pattern are recorded on the recording medium. During a reproducing process, the information is read out from the recording medium and an information signal representing the readout information is generated. In addition, the reference pattern is read out from the recording medium and a reference signal representing the reference pattern is generated. The information is demodulated from the information signal. The reference signal is used in the demodulation of the information from the information signal.

Abstract: In cases where a first communication control unit locks a second communication control unit to communicate with the second unit, the first unit stores a data representing a time remaining until the locking of the second unit is released. In these cases, the second unit stores a data representing an address of the first unit as a lock address corresponding to an address of a unit which locks the second unit. In cases where a third communication control unit tries to communicate with the second unit and fails the communication with the second unit, the third unit connects with the second unit and reads out the data representative of the lock address from the second unit, and then the third unit connects with the first unit in response to the lock address and reads out the data representative of the lock remaining time from the first unit. The third unit retries to communicate with the second unit after the lock remaining time elapses.
