Title: Digital transmission system
Inventor: TAKASAKI YOSHITAKA
IPC: H04L25/49
Filed: 1988-12-28
Abstract: PURPOSE:To simplify a short range transmitter and to facilitate the extraction of a clock signal by constituting a transmission line code such that the violation of the code rule is utilized to demultiplex and insert a special signal and a correction signal or the like separately and a clock component can be extracted with a simple logic processing. CONSTITUTION:In the case of a 1B4B code, an original signal (a) is subjected to 1B4B coding to obtain a waveform (b). According to the coding rule, an original signal 1-bit being 'x' is coded as '10x0'. However, in a time slot shown by an arrow, violation is used to apply coding of 11x0. The waveform (b) is retarded by one time slot of te original signal to obtain a waveform (c), both waveforms are ANDed to obtain a pulse train. A waveform (f) is obtained by ORing the pulse train (d) and a train resulting from retarding the train (d) by 1/2 time slot of the original signal. While the waveform is used as a clock as it is, the waveform is applied to an optical PLL or the like, the clock is stably extracted. When a clock waveform resulting from retarding the waveform (f) by 1/4 time slot of the original signal is ANDed with the waveform (b), a frame pulse (g) due to the violation is detected.

Abstract: PURPOSE:To enhance operating efficiency by timely making an operating state detection signal unavailable to switch main relief valves to high relief pressure and to drive actuators at high pressures in any operating state of shovel operating actuators. CONSTITUTION:When all directional control valves 3-8 of shovel operating actuators 11-14 and travel actuators, 7, 8 are set at neutral positions, main relief valves 9, 10 are set to high relief pressures by pressurized oil of a pilot pump 68.

Further, for example, when the rated workload of a bucket hydraulic cylinder 14 is exceeded, an electromagnetic selector valve 64 is moved to discharge the pressurized oil of the valve 66. When the valve 66 is then raised, the pressurized oil of the valve 68 is introduced into an oil passage 67 to set the valves 9, 10, to high pressures, and a highly pressurized oil is fed to the cylinder 14.

Title: Magnetic refrigerator
Inventor: FURUMOTO HITOSHI
IPC: F25B21/00
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To avoid the generation of the Joule heat and reduce a drop of refrigeration by a method wherein a composite oxide, such as a high-temperature superconductive ceramic, which presents a superconductive phenomenon in the range of an operating temperature in a magnetic refrigerator, is vapor-deposited on constitution members which are influenced by a magnetic field. SOLUTION: A superconductive magnet 8 is so provided as to surround a magnetic working material 1 and a heat pipe 6 and is positioned in a magnetic field. During the cycles of heat insulation magnetization, isothermal discharge of heat, heat insulation demagnetization and isothermal absorption of heat, an eddy current caused by the formation of a magnetic field flows to peripheral members of the superconductive magnet 8 to generate the Joule heat, so that a great drop of refrigeration is caused particularly in a thermal switch 2 and a thermal conductive body 4 on a high- temperature side. However, high-temperature superconductive ceramics 9, 9a are vapor- deposited on the surfaces of a terminal 2b and the thermal conductive body 4, which are members to be influenced by the magnetic field of the superconductive magnet 8.  Therefore, when a temperature reaches a critical temperature level or below, they become superconductive, and, when the superconductive magnet 8 is excited, a leaking magnetic flux is prevented from being invaded into the interior of a base material, and the generation of the Joule heat is avoided.

Abstract: PURPOSE:To simplify a gradation image recording by a recording image forming method wherein an ink is dissolved in a solvent according to a heating, and the dissolved ink is depressed to an image receiving body to be absorbed into the image receiving body. CONSTITUTION:A laser light 13 generated from a laser generator 4 according to a recording signal from a recording signal issuance source is applied onto an ink roller 1 to locally heat an ink 9 to produce a temperature-increase ink part 14. Before the temp. of the temperature-increase ink part 14 is lowered to room temp., the temperature-increase ink part 14 is brought into contact with an image receiving body 3 by the rotation of the ink roller 1. Before coming into contact with the ink roller 1, the image receiving body 3 has been coated with a solvent 2 by a solvent coater 5 and impregnated with the solvent 2 in fine pores 11. Therefore, at the contact of the image receiving body 3 with the ink roller 1, the ink 9 is dissolved in a solvent 16 contained in the pores in proportion to the temp. of the ink 9. Thereafter, a platen 6 is rotated, whereby the image receiving body 3 is released from the ink roller 1, and the dissolved ink 9 is transferred to the image receiving body 3 to form a recording image 19 thereon. In this manner, the recording image having good fixing properties and half tones can be easily obtained.
