Title: Vaporizing combustion device
Inventor: SAITOU TOSHIHIKO
IPC: F23D11/02
Filed: 1977-10-18
Abstract: PURPOSE: To reduce generation of soot, eliminate backfire and reduce the time required for extinction, by specially designing the structure of a premixing chamber.  
     CONSTITUTION: Additional parallel bottoms 3, 4 are formed below the bottom of a combustion chamber 2, and a buffle 6 and porous plate 8 are fitted between them to compose a premixing chamber 5. When fuel is dripped from a fuel pipe 1 in the premixing chamber 5 preheated up to a certain temperature by means of an electric heater 7, vaporized fuel is mixed with combustion air fed through an air passage 12 and ignited on the porous plate 8 by means of an ignition heater 16 to form a flame. Combustion continues with combustion air fed through another air passage 11, the flame being stabilized by a stabilizing rod 9 and fuel is perfectly burnt in a red heat combustion cylinder 18. Air from the air passage 12 cools the periphery of the porous plate 8 to eliminate back-fire and the time required for extinction is shortened due to a reduced size of the oil reservoir

Title: Control device of hydraulic construction machinery
Inventor: NISHIDA TOSHIAKI
IPC: F15B20/00
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a control device of a hydraulic construction machine which is excellent in safety and can prevent a hydraulic actuator from running uncontrolled even if a control solenoid valve installed in the pilot line of a hydraulic device gets seized. SOLUTION: A pilot hydraulic pressure p and a pilot oil temperature Tm in a detecting pilot line T6 connected to the downstream of electromagnetic proportional reducing valves 13a to 13c are measured using a pressure detector 11 and a thermosensor 17, respectively. For example, the pressing operation of a switch 10 is released, and an opeartion delay time between a time when the driving current of the electromagnetic proportional reducing valve 13b is reduced to zero and a time when the pilot oil pressure p in the detecting pilot line T6 detected by the pressure detector 11 is reduced to a limit pressure is calculated. If the operation delay time exceeds a proper operation delay time, a control device 9 judges that the operation of the electromagnetic proportional reducing valve 13b is faulty, and outputs a drive current to close an electromagnetic switchover valve 14.

Title: Optical disk device, optical disk recording method, optical disk and optical disk reproducing method
Inventor: KOBAYASHI SEIJI
IPC: G11B7/24079
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To enable plural data strings to be dispersedly recorded for a relatively long distance on an optical disk by respectively modulating plural pairs of orthogonally crossing reference signals with plural data strings to be recorded and recording them by changes in group or the like to multiplex the plural data strings. SOLUTION: Phase units with a shift angle of +45 deg. 27A to 27D and phase units 28A to 28D of -45 deg. form generate plural pairs of orthogonally crossing reference signals S1 to S8 whose frequencies are different. Multiplying circuits 36A to 36H multiply respective reference signals S1 to S8 by polarity signals P0 to P8 which are respectively outputted from level converting circuits 20A to 20H to modulate them with corresponding polarity signals P0 to P8 and output them. In amplifier circuits 37A to 37H, gains K1 to K8 are set so as to increase as frequncies of respective modulated signals V1 to V8 being amplification objects become higher so that amplitudes of the respective modulated signals V1 to V8 which are detected at the time of reproduction becomes roughly equal. Thus, the frequency characteristic of a recording and reproducing system is corrected.

IPC: G08B5/00
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To confirm trouble information through easier operation by providing a priority varying means which lowers the display priority for specified information with an external command. SOLUTION: When trouble information has a newly generated or restored item, a host computer 1 adds priority set previously on a console device 2 to the information and sends them to the information display device 7. If a fault occurs, on the other hand, the trouble information and priority are added to a trouble information list and further the priority level is read out of the list and decided as a new priority level. Namely, the priority level enabling operation by a remote control unit 5 is set for the previously set priority level. A control part 3 displays the information of the trouble information list on a display unit 4 in the order of the new priority level. Consequently, trouble information of low priority which was not displayed so far and trouble information of low priority to be generated in future can be displayed on the display screen of the display unit 4.
