Title: Error correction/conceiling apparatus and video and/or audioreproducer
Inventor: YOSEFU FUBERUTOUSU PETERUSU
IPC: H04N5/94
Filed: 1985-07-30
Abstract: A device is described for correcting and concealing a data stream which is block-wise provided with redundancy. The redundancy has an error-correction capability per block. The blocks are received from a medium in a systematically distributed manner. After regrouping, error-signalling is formed per block by way of the error-correction code. For a number of successive blocks the total number of expected errors is compared with a threshold which lies within the error-correction capability of the code. When this threshold is exceeded, concealing takes place, even when the total maximum correction capability of the code has not yet been fully utilized.

Filed: 1982-09-25
Abstract: PURPOSE:To make uniform temperature distribution at the upper and lower parts of an electrolyte to prevent deterioration of a plate by immersing in the electrolyte a good heat conductive pipe which contains a material evaporating or condensing at atmospheric temperature, and its both ends are sealed. CONSTITUTION:A copper pipe 4 is in contact with an eletrolyte 3 and methanol 5 accommodated in the pipe evaporates at the lower part where temperature is high to absorb latent heat and condense at the upper part where temperature is low to generate heat, that is, the lower part is cooled and the upper part is heated to make temperature uniform. Methanol 5 is converted to liquid at the upper part and flows to the lower part by gravity, and it evaporates again when temperature at the lower part is high. The pipe comprising other metal such as aluminum, iron is used in place of the copper pipe 4. Inorganic or organic materials having good acid resistance are used in addition to lead or lead alloy as a material covering the outer surface of the pipe, but good heat conductivity is essential. Bonding of the copper pipe 4 with plates is preferable to act as a fin.

Abstract: PURPOSE:To reduce the variation of clearance in a ball bearing fixing position owing to a thermal expansion, by arranging a saucer type spring at the position where inner rings of the bearings and a cylindrical member to define the interval of the inner rings are set to a rotary shaft. CONSTITUTION:Inner rings of ball bearings 4a and 4b, and a cylindrical member 7 are set to a rotary shaft 3, and they are connected integrally by a nut 14 through a washer 12 and a saucer type spring 13 with a relatively large spring rating.

Title: Stirling engine
Inventor: NOMAGUCHI TAMOTSU
IPC: F28F1/12
Filed: 1982-09-25
Abstract: PURPOSE:To enhance the miniaturization and heat efficiency of a Stirling engine, by forming a recesses in the outer surface of cooler pipes which cool working medium from the outer surface with the use of cooling medium. CONSTITUTION:A cooler 6 shorter than a conventional cooler is formed with recesses 61 having a depth less than one-third of the pipe-wall thickness in the outer surface of the cooler pipes, and therefore, the heat transmitting area is enlarged without the proof-pressure of the cooler pipes being largely deteriorated. Thereby, the effective heat transmitting rate may be made high, and the length of the cooler is shortened so that a loss in air-feed is reduced and also the dead space volume is reduced. With this arrangement, the volume of the cooler occupied space is reduced to enhance the compression ratio. Further, the heat efficiency may be enhanced due to the reduction of loss in air-feed.
