Title: Trellis coding method
Inventor: NODA MAKOTO
IPC: H03M13/23
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To allow a method to obtain a matched spectral null type trellis code exempted from a quasi-destructive code where a high code generating efficiency and a simplified configuration of decoder are attained. SOLUTION: A matched spectral null type trellis code that is generated by a time changing trellis line diagram, which eliminates a quasi-destructive code series by deleting part of paths on a trellis line diagram is coded by combining two kinds of code series (codes A, B) the state number of which, tacking a code polarity of a start point and an end point of the code into account, is respectively 2. Since the code generating efficiency is improved by the coding method, a code with high coding rate is generated. Thus, the method contributes to enhanced recording line density in a recording and reproducing device in, e.g. a magnetic recording system. Furthermore, the configuration of a decoder is made comparatively simple.

IPC: G01N33/26
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To simulate a condition similar to a practical refrigerator cycle by sealing artificial residual oil produced by heating an oil used for copper-tube together with a refrigerant, refrigerating machine oil to perform testing. SOLUTION: After a separable flask 2 is sufficiently dried by dry nitrogen gas, copper tube oil 3 is injected, and active gas such as oxygen in the air of the flask is purged by nitrogen gas. A cooler 1, caps and like are wholly removed, the oil 3 is heated and evaporated by a mantle heater 4, gasification is successively performed from a boiling component, and exhausted from an exhaust port 7. Next, when the cooler 1 and the like are attached and the tube oil 3 is condensed by the cooler, while the residual oil 3 is being gasified, the condensed tube oil 3 is dropped in the flask 2, and reaction is repeated by copper powder 5.  Consequently when artificial residual oil having a property similar to practical residual oil is produced and used in a shield tube test, chemical stability of the oil can be accurately evaluated, since a condition similar to a practical refrigerator cycle can be simulated.

Abstract: PURPOSE:To obtain an instruction combining test device for a transferring device which can investigate the reproducibility of an error by managing without work to issue a special program for the reproducibility or the investigation of the error to the transferring device at the time of the occurrence of the error. CONSTITUTION:In a test to confirm the normality of the transferring device by comparing an expected value obtained by issuing the channel program of the random combination of instructions to the transferring device 21 with the expected value obtained by simulation, in the case of the occurrence of the error, the transferring device 21 is stopped in order to obtain the error information of the transferring device 21.

Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To improve driving safety, by detecting a level of a reflection wave for a time difference equivalent to distance from an antenna radiation edge to a signal transmission/ reception separation circuit, and setting and changing an alarm limit value. SOLUTION: An operation circuit 3 detects a reflection wave level based on a time difference equivalent to distance from a radiation edge of an antenna 2 to a signal transmission/reception separation circuit and detects the snow accretion of the antenna 2. While a vehicle is driving, snow accretion a constantly detected and a snow accretion elimination device 7 is started or stopped according to the presence or absence of snow-accretion. When the period of a snow accretion operation is smaller than a lower-limit judgment value, it is judged that a heavy snowfall including a snowstorm resulted and an alarm limit value is automatically set to a far mode. When a snow removal period is larger than the lower limit judgment value and smaller than a middle judgment value, it is judged that a medium degree of snowfall resulted and then alarm limit value is automatically set to a far mode.  When snow removal period is larger than a middle judgment value and smaller than an upper-limit judgment value, it is judged that a light snowfall or rain resulted and the alarm limit value is automatically set to a middle mode. When the period of the snow removal operation is larger than the upper-limit judgment value, a normal mode is automatically set.
