Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for managing life times of parts in a single crystal pulling device, quantitatively grasping the life times of the parts and enabling the quality stabilization of the pulled up single crystal and the reduction of products below standards, and a device used to perform the method. SOLUTION: This part management device 1 is equipped with a calculating part 2 for a regression coefficient and an alarming part 3, and connected to plural single crystal pulling devices 4. The calculating part 2 for the regression coefficient prescribes a life time for each of the parts based on the inputted data and feeds to the alarming part 3. When a datum on a number of uses or a used time of each of the parts obtained from the single crystal pulling up devices 4, reaches to a value prescribed by the calculating part 2 for the regression coefficient, the alarming part 3 judges that the part reaches to its life time and gives a warning by a method such as by buzzing or displaying on a displaying device to prompt the exchange of the part.

Title: Image-recording head
Inventor: SAITO KOICHI
IPC: B41J2/05
Filed: 1986-03-27
Abstract: PURPOSE:To ensure easy selection of an ink and enable high-speed recording, by providing a liquid coloring agent having a volume resistivity not less than a specified value and making direct contact with heat generating resistors or lead electrodes. CONSTITUTION:The volume resistivity of a liquid coloring agent disposed to make direct contact with heat generating resistors or lead electrodes is selected to be not less than 10<6>OMEGA.cm. If the volume resistivity of the ink is not more than 10<5>OMEGA.cm, the phenomenon in which flying of the ink is not achieved may often occur. This is because of leakage occurring between adjacent ones of the electrodes 18 due to the ink, which results in that the heat generating resistor 16 does not generate sufficient heat. When a liquid coloring agent having an electric resistance not less than a predetermined value is used, short-circuiting between the electrodes can be prevented from occurring, even when the coloring agent 13 makes direct contact with the heat generating resistors 16 arranged in an array or the lead electrodes 18. Accordingly, it is unnecessary to provide an insulating layer or the like on the lead electrodes, and the coloring agent 13 can be efficiently heated. In addition, since the speed of raising the temperature of the ink is enhanced, high-speed recording can be performed.
