After the solvent is stirred, the polymerizable product is taken out of the solvent and is dried. The polymerizable monomer is a styrene monomer, acryl monomer, etc., and the coloring agent is usable by incorporating a coloring pigment into the monomer. The coloring agent and the monomer are used at 1:100-20:100 ratio by weight. Polyvinyl alcohol, etc., are used as the dispersion stabilizer to stabilize the polymerizable compsn. as oil drop particles by suspending the same into a water medium. The toner having the excellent flowability, moisture resistance and durability is produced in a short period of time with high productivity in this way.

Title: Self-diagnostic system for multiprocessor system
Inventor: YORITA KOJI
IPC: G06F11/22
Filed: 1989-05-29
Abstract: PURPOSE:To shorten the overall diagnostic time of a multiprocessor system by performing a the exclusive control to secure the diagnostic right of the shared resources by reference to the diagnostic information after the batch diagnoses of its own device and a proper storage and setting its own identifier to the diagnostic information by arithmetic controller which diagnoses the shared resources by means of the diagnostic right. CONSTITUTION:The respective arithmetic controllers PU1 - PUn which received collectively the diagnostic start from a system controller SYU diagnose their own devices and a proper storage PMn and check the diagnostic state of the shared resources by reference to the diagnostic information. Then no process is carried out if the shared resources are already diagnosed or separated. At the same time, an undiagnostic state can be immediately detected since the controllers PU1 - PUn always refer to the diagnostic information. If an undiagnostic state is detected, the identifier of its own device is set to the diagnostic information and the shared resources are diagnosed. At the same time, the 1-bit information showing 'under diagnosis' is set to the diagnostic information. As a result, the overall diagnosing time can be shortened for a multiprocessor system without performing such processes to check previously the system constitution.

IPC: F28D15/06
Filed: 1992-04-28
Abstract: PURPOSE:To permit the efficient cooling of the inside of a casing by a method wherein an air temperature in the casing is regulated so as to be a specified temperature. CONSTITUTION:A control valve 63 controls the flow rate of cooling liquid 60 by a flow rate control signal from a temperature regulator 64 while the temperature regulator 64 sets the flow rate control signal based on a temperature data from a temperature sensor 65. In this case, an air temperature in the casing 1 is detected by the temperature sensor 65 and the opening and/or closing of the regulating valve 63 is controlled by the temperature regulator 64 so that the temperature in the casing is stabilized at a preset temperature whereby the flow rate of the cooling liquid 60 is regulated and the heat transfer rate of the heat radiating section 31 of a heat pipe 3 is changed to increase and/or decrease the exchanging amount of heat. According to this method, the air temperature in the casing 1 can be set freely while the inside of the casing 1, in which heat generating instruments are stored, can be cooled stably and efficiently.

Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a capacitance type height sensor which has the least possibility to get the bad insulation between the sensor and the torch body, and reduces the maintenance man-hours and the parts cost. SOLUTION: The outer diameter of a sensor 12b, at the part set closer to a torch body 11a, is larger than that of the torch body 11a, at the part set closer to the sensor 12b. The larger outer diameter of the upper part of the sensor 12b prevents a spatter of a processing material 7 and the like from reaching the surface of an insulating layer 111a and being stuck. As a shape of the sensor, it is acceptable, other than a reverse cone, to install a flange part on the upper part. Furthermore, if the flange part is made detachable, it is useful to reduce the maintenance man-hours and the parts cost.
