IPC: G05B19/19
Filed: 1990-07-07
Abstract: PURPOSE:To detect the deviation abnormality in a fixed short time regardless of the velocity by calculating automatically the deviation abnormality detection threshold value and setting the optimum threshold value in real time in response to the due command velocity. CONSTITUTION:The feedback processing is carried out through a servo control part having a function to feed back the current supplied from a driver 6 and to perform a velocity feedback operation of the encoding pulse of an encoder 8 via an F/V converter 9 and a position detector 10 which counts the encoder pulses and detects the present position of an industrial robot.

Title: Fuel-injection pump
Inventor: NAKAJIMA YORIYASU
IPC: F02M59/36
Filed: 1983-09-30
Abstract: PURPOSE:To make maximum discharge pressure settable, by installing a read valve in the lower end of a rotary type sleeve as well as installing an adjusting rod, which reduces its mass, free of vertical motion, in case of a jerk type fuel- injection pump. CONSTITUTION:A plunger 1 is pushed upward by a fuel cam and thereby closes a port 3 but the oil hole of a small sleeve 6 is interconnected to an oil feed chamber 5 by way of an oil passage of an adjusting rod 7, therefore pressure is in no case intensified. With successive pushing up, when an oil hole of the small sleeve 6 is closed, pressure inside a plunger chamber 4 goes up and discharge gets starting. When further the plunger goes up and its controlling groove's lower part adjoins the port 3, fuel flows into the oil feed chamber 5 from a chamber 4 and the discharge comes to an end. With this adjusting rod 7 moved up and down, discharge timing is adjustable whereby maximum pressure inside a cylinder of an engine is controllable. When the adjusting rod 7 is situated in a more upper position than that in a plunger stroke, the fuel is no longer discharged so that the engine is stoppable.

Title: Determination of nucleic acid base sequence
Inventor: FUJII HIDEHIKO
IPC: G01N33/50
Filed: 1986-07-30
Abstract: PURPOSE:To determine base sequence at a short migration distance by measuring the fluorescent spectra of nucleic acid fragments preliminarily subjected to fluorescent labeling and subjecting the same to component analysis by arithmetic processing. CONSTITUTION:The samples which are preliminarily labeled for each kind of the base sequences by four kinds of suitable fluorescent agents are subjected to electrophoresis. The fluorescent spectra of the zone of the nucleic acid fragments are measured during the migration. The spectrum having the peak wavelength nearest the max. fluorescent wavelength of the received spectra among the preliminarily stored fluorescent spectra of four kinds of the fluorescent agents is selected and the spectrum so selected as to have the fluorescent intensity equal to the fluorescent intensity of the spectrum received at the peak wavelength of the selected spectrum is multiplied by a constant and is subtracted from the received spectra in an arithmetic circuit 9. The spectra except the spectrum selected by the above-mentioned operation are similarly subtracted from the remaining spectra. If the constant required for the multiplication by the constant is larger than the certain threshold value, judgement is made that the fluorescent material thereof exists.
