Title: Cash coherence system
Inventor: POORU KEI RODOMAN
IPC: G06F12/08
Filed: 1985-02-08
Abstract: A cache coherence system for a multiprocessor system including a plurality of data processors coupled to a common main memory. Each of the data processors includes an associated cache memory having storage locations therein corresponding to storage locations in the main memory. The cache coherence system for a data processor includes a cache invalidate table (CIT) memory having internal storage locations corresponding to locations in the cache memory of the data processor. The cache coherence system detects when the contents of storage locations in the cache memories of the one or more of the data processors have been modified in conjunction with the activity those data processors and is responsive to such detections to generate and store in its CIT memory a multiple element linked list defining the locations in the cache memories of the data processors having modified contents. Each element of the list defines one of those cache storage locations and also identifies the location in the CIT memory of the next element in the list.

Title: Lighting device
Inventor: NISHI TAKECHIKA
IPC: G03F7/20
Filed: 1988-02-03
Abstract: PURPOSE:To prevent a speckle from being generated sufficiently and to provide uniform lighting by splitting the light outputted by a light source into reflected or transmitted light beams, and putting the split light beams together after giving them a larger optical path difference than a coherence distance of light. CONSTITUTION:The light outputted by the light source 12 is split by a means 100 which reflects part of the light and transmits the remainder. A triangular prism optical system 100 consists of a 1st regularly triangular prism 102 and a 2nd prism 104 and when light is incident on those triangular prisms 102 and 104, the light is reflected internally by two surfaces except the incidence surface and exits from the incidence surface. The split light beams are put together after being given the larger optical difference than the coherence distance of light, so the composite light is reduced in coherence with time. Consequently, even when spatial coherence increases because of the use of an injection locking method, etc., the time coherence is low, so the lighting is performed without generating any speckle.

IPC: G11B5/23
Filed: 1990-01-31
Abstract: PURPOSE:To relieve the waviness to be generated by secondary pulses by forming two layers of magnetic metallic thin films which are substantially the same in film thickness on the trailing edge side of a working gap and forming a side gap consisting of a nonmagnetic thin film of a specific thickness between these two magnetic metallic thin films. CONSTITUTION:Two layers of the magnetic metallic thin films 5, 7 which are substan tially the same in the film thickness on the trailing edge side of the working gap 11 and the side gap 12 consisting of the nonmagnetic thin film of <=2000Angstrom  thickness is formed between these two magnetic metallic thin films 5 and 7. The main pulses by the working gap and the secondary pulses by the pseudogap at the boundary be tween the magnetic metallic thin film 5 and the oxide 2 of the magnetic material are generated and the side pulses by the side gap 12 are generated between the two magnetic metallic thin films 5 and 7. The thickness of the two magnetic metallic thin films 5, 7 is, therefore, adequately selected with respect to recording wavelingths, by which the secondary pulses and the side pulses are superposed on the main pulses by reversing the phases by 180 deg. with each other at the same timing, by which the side pulses and the secondary pulses are negated with each other. The influences of the side pulses and the secondary pulses are apparently eliminated in this way.

Abstract: PURPOSE:To prevent degradation in function by forming a bypass water path in parallel with a water treatment part in which filter media are packed and switching a water flow passage to the water treatment part to the bypass water path by a hot water inflow preventive device which operates by detecting the hot water. CONSTITUTION:The shape of shrunk springs is stored as a memory shape into the open/shut springs 3C, 4C of a hot water inflow preventive valve 3 and a hot water discharge valve 4 and the shape of an elongated spring is conversely stored in the open/shut spring 7C of a backflow preventive valve 7. The open/ shut spring 3C of the hot water inflow preventive valve 3 attains the low temp. below a reset temp. by touching ordinary temp. water when the water of the ordinary temp. is supplied to this device from an intake pipe 2. The spring is then easily elongated even by the weak water pressure received by a valve disk 3b, by which the valve port 3a is opened to form the flow passage to the water treatment part 6. The feed water is thus cleaned in the water treatment part 6. The inflow of the hot water is thereby surely prevented.
