Title: Device for compressing and extending dynamic image data
Inventor: NAKAGAWA AKIHITO
IPC: H04N19/60
Filed: 1995-05-15
Abstract: PURPOSE: To reduce the sense of discontinuity to be generated in an extended image when compressing processing is performed to a dynamic image for each block. CONSTITUTION: A frame memory circuit 10 successively stores dynamic image data VIN for the unit of an image (frame). In a certain frame cycle, a read control circuit 12 generates and outputs a block equally divided in the range of an original image and in the next frame cycle, the frame memory circuit 10 is controlled so as to generate and output a block dividing a picture so as not to be overlapped with the boundary of the block in the preceding frame cycle. A compression encoding circuit 14 performs DCT processing successively to the blocks inputted from the frame memory circuit 10 and further executes compression encoding by performing quantizing processing and variable length encoding processing.

Title: Closing pressure release control method for injection molding machine
Inventor: TAKAHASHI RYUICHI
IPC: B29C45/50
Filed: 1994-05-30
Abstract: PURPOSE:To eliminate the influence of residual closing pressure on the injection process at the time of transition from closing process to injection process. CONSTITUTION:Oil is fed through a variable pump 23 into the oil chambers 39, 41 of a closing cylinder 35. Upon finishing the closing operation, a valve disposed between the variable pump 23 and an oil tank 29 is opened for a predetermined time and the pressure on the delivery side of the variable pump 23 is released to the oil tank 29. Subsequently, the valve is closed and oil is fed from through the variable pump 23 to the oil chamber 20 of the injection cylinder 35 thus starting the injection process. In this regard, hydraulic pressure on the injection cylinder 35 side can also be released by opening the valve. This constitution prevents the residual closing pressure from effecting adversely on the injection process.

IPC: B26B13/00
Filed: 1987-05-15
Abstract: PURPOSE:To obtain an instrument that automatically repeats a shearing action similar to the actual one and stops at the time of an overload by sliding a movable cutting edge on a fixed cutting edge by an opening and closing mechanism, setting a lengthy sheet-shaped object to be sheared perpendicularly to the plane of an opening and closing action and in parallel to the fixed cutting edge, feeding the object while interlocking with the movement of the movable cutting edge and providing a stop mechanism for the overload. CONSTITUTION:A power switch 18 is turned ON and a counter 20 is set to zero in advance. Then, a reset switch 22 is depressed and a movable cutting edge 3 is rendered an open condition with respect to a fixed cutting edge 2. A set object 12 to be sheared is inserted in between an elastic roller 24 and a guide 4. When an opening and closing speed is set 26 and a start switch 28 is depressed, the cutting edge 3 begins an opening and closing action and the object 12 to be sheared is fed once when the cutting edge 3 is opened once. A counter 20 counts one every time when the object 12 is sheared. As a test continues, the cutting quality of the cutting edges 2, 3 are deteriorated and a load is increased above a set value, and a stop mechanism stops the opening and closing action of the edge 3. The durability of the cutting quality of scissors is evaluated from the counted value of the counter 20 obtained heretofore.

Abstract: PURPOSE:To modulate under a low current injecting condition at a high speed by shifting the bottom of the conduction band of a collector layer to an energy position equal to or smaller than n=1 quantum level, and discharging electrons by tunneling from a base layer to the collector layer. CONSTITUTION:An optical waveguide is formed of an emitter layer 2 having a conduction band disposed at its bottom at an energy position for supplying electrons by tunneling to a quantum level of n=2 or more of electrons, and a collector layer 6 having a band gap larger than that of a quantum well and a conduction band disposed at its bottom at an energy position larger than n=1 of quantum level of the electrons as clad layers. A bias voltage is applied between the layers 5 and 6 to shift the bottom of the conduction band of the layer 6 to an energy position having equal to or smaller than n=1 quantum level, thereby discharging the electrons by tunneling from the layer 5 to the layer 6. Thus, a high modulation speed is obtained under low current injecting condition.

Title: Data recording method
Inventor: KADOKAWA YUICHI
IPC: G11B20/10
Filed: 1988-05-16
Abstract: PURPOSE:To easily perform coding without the need for a key by placing the data words to be encoded at the redundant words position for error correction at encoding time and the redundant word for error correction for the encoding data words at the data words position. CONSTITUTION:A data word D is recorded at the parity word position where a parity word P is written originally and the parity word P for error correction for the data word D is recorded in the data word position where the data word D is written originally. Due to, therefore, the recording positions of the data word D and parity P becoming in a reversal arrangement state at the encoding time, the decoding of the data recorded by encoding by its reading is made impossible unless the data output circuit outputting the data ward D written at the parity word position by its selection is provided. The encoding of the data can easily be performed without the need for a key.
