Abstract: There is provided a new signal processing device that uses functions appropriate to signal properties to acquire high-quality signals. The signal processing device includes a sampling circuit 2 that samples an input signal and outputs a discrete signal, multiple function generators 3 that generate multiple sampling functions with parameters m different from each other, plural inner product operating units 4 for each of the parameters m that take an inner product between the input signal and each of plural sampling functions and output an inner product operating value, and a judging unit 8 that determines parameter m providing a minimum error out of multiple errors composed of differences between the sampling value and inner product operating values output from the multiple inner product operating units and outputs the parameter m signal. The signal processing device outputs a discrete signal composed of a string of the sampling values and the parameter m signal.

Abstract: A vibration isolator includes an upper coupling member to be mounted on a vibrating body, a cup-shaped holder to be mounted on a car body, and a rubber-like insulator which is located between the upper coupling member and the cup-shaped holder to isolate vibrations from the vibrating body. The vibration isolator further includes a main chamber and a subchamber, which are arranged in series with the insulator and in which a liquid, an incompressive fluid, is enclosed, an annular orifice interconnecting the main chamber and the subchamber, a partition member dividing the main chamber and the subchamber, a diaphragm which is made of a rubber membrane-like member and defines a part of the subchamber, and an air chamber formed below the diaphragm. Both the partition member and the diaphragm are entirely formed of rubber-like elastic bodies. This provides a large area for the central flexible portion of the partition member, reducing the manufacturing costs of the parts including the diaphragm.

Abstract: A color cathode ray tube includes an envelope having a front panel and a funnel joined to periphery of the front panel; a phosphor screen disposed on an inner surface of the front panel; a shadow mask disposed to face the phosphor screen and having a plurality of apertures for passing electron beams; an electron gun disposed in a neck of the funnel and emitting the electron beams toward the shadow mask; and a magnetic shield disposed within the envelope and surrounding a path along which the electron beams travel. The magnetic shield has a first side plate, a third side plate facing the first side plate, a second side plate, a fourth side portion facing the second side plate, a first opening on the side of the shadow mask, and a second opening on the side of the electron gun, thereby forming almost a hollow frustum of quadrangular pyramid, and only each of the first and third side plates has notches in the vicinity of both ends of edges of the first and third side plates on the side of the second opening.

Abstract: A multiprocessor system includes a plurality of processors for decoding and executing instructions, a main storage, and a plurality of buffer storages for storing copies of data stored in the main storage, wherein transfer of blocks of data is performed among the plurality of buffer storages. When data required by a given one of the processors is absent from the nearby buffer storage, a block address at which the data block including the required data is located and an intra-block address at which the required data is located in the data block are sent out to another buffer storage, where decision is made on the basis of the intra-block address as to which data is required by the processor requiring the data, whereupon the required data is transferred to the nearby buffer storage of the processor with priority over the transfer of other data in the data block including the data to be transferred.

Abstract: A cathode ray tube has a metal funnel welded to a metal skirt. The skirt is reinforced to resist tensile stress. Reinforcement is accomplished by thickening the skirt, or corner portions thereof; by welding one or more reinforcing members to the inside or outside of the skirt; by bending the edges of the skirt and funnel and welding the bent parts together; by welding reinforcing plates to corners of the skirt and winding a tension band around the skirt; or by providing a rigid frame with compression members to press inward on the skirt.

The glass faceplate has a phosphor screen coated on the inside surface and a metal film covering the phosphor screen. A high voltage of 25 KV is applied to the metal film, while the metal funnel is grounded. An insulating layer covers adjacent inside areas of the funnel and faceplate, thereby increasing the distance between the metal film and exposed surfaces of the funnel and preventing creeping discharges.

The inner peripheral surface of the thick wall portion is in contact with the outer peripheral surface of the rod. A gap, which is wide enough to receive the hydraulic fluid, is defined between the inner peripheral surface of the thin wall portion and the outer peripheral surface of the rod. A drain recovery hole is connected between the high- and low-pressure sealing devices.

Abstract: In a lock control for a shared storage, each storage controller (SC) includes circuitry (LKA) for holding the addresses locked by any of the storage utilizing units connected thereto and circuitry (FLKA) for holding a copy of the contents of LKAs of the other SCs. When one storage utilizing unit connected to one SC issues a storage access request, its requested address is compared with the contents of the LKA and FLKA in the associated SC, thus determining whether or not the requested address is locked by any other storage utilizing unit connected to that particular SC or by any of the storage utilizing units connected to the other SCs. Each storage utilizing unit may include a FLKA.
