Title: Method for preventing freezing of cooling liquid in cooling device
Inventor: HOYA YOSHIHIKO
IPC: F25B47/02
Filed: 1994-07-18
Abstract: PURPOSE:To surely prevent freezing by a method wherein a temperature of cooling liquid is detected by a temperature sensor, a circulation pump is intermittently operated in response to its stop time and an operating time when the detected temperature is lower than its predetermined upper temperature and exceeds its lower temperature and in turn the circulation pump is ocntinuously operated up to a time when the temperature reaches a predetermined middle temperature when the detected temperature is lower than the lower temperature. CONSTITUTION:Cooling liquid W is circulated by a circulation pump 3 to a cooled item 4 so as to cool the cooled item 4. Under this state, an upper temperature Tu, a middle temperature Tm and a lower temperature Td (where, Tu>Tm>Td) are set in advance and a temperature of the cooling liquid W is detected by a temperature sensor 5. In the case that the detected temperature Tp becomes the upper temperature Tu and exceeds the lower temperature Td, the circulation pump 3 is operated intermittently for the stop time tx and the operation time ty. In addition, when the detected temperature Tp becomes lower than the lower temperature Td, the circulation pump 3 is operated continuously until the detected temperature Tp becomes the middle temperature Tm. With such an arrangement as mentioned above, it is possible to perform a sure prevention of freezing and to realize its energy saving characteristics.

Title: Method for washing electrostatic precipitator
Inventor: MIYAMOTO MASAHIRO
IPC: B03C3/80
Filed: 1988-07-28
Abstract: PURPOSE:To enhance effect of a washing method wherein air spray is performed before blast drying by holding the dampers of an air outlet side in a half-opened state for a constant time in the meantime when the dampers are wholly opened in the case of opening these dampers according to start of a blasting stage during the spraying stages of water and air. CONSTITUTION:When the inside of a dust collecting unit 2 is dried, the damper 40a of an air inlet side are immediately wholly-opened but in the meantime when dampers 40b of an air outlet side are wholly opened, the operation is stopped at once. The half-opened state is held for several ten seconds and thereafter the dampers are wholly opened and blast is continued for about 10 minutes. In this state, the dampers 40b are mutually overlapped against the flow of wind sent from a fan and this wind is allowed to collide against the dampers and thereafter directed to the outside of the dust collecting unit 2 because its direction is changed by the dampers 40b. Therefore, washing water is blown off in an air spraying stage and made foggy and levitated in the space of the unit 2. This levitated washing water is allowed to collide against the dampers 40b before it is carried to the outside of the unit while being accompanied with the wind and allowed to flow down along the dampers 40b and collected to a water reservoir and sent to a sewage tank.

Title: Cpu abnormality processing method
Inventor: MORIMOTO AKIRA
IPC: G06F15/16
Filed: 1989-07-24
Abstract: PURPOSE:To detect the abnormality of a slave CPU by a master CPU by deciding the on-state of a computing flag after transferring data with a shared memory. CONSTITUTION:A system with constitution of master/slave type CPU consists of a master CPU part 1, a slave CPU part 2, and a memory shared part 3. The master CPU part 1 and the slave CPU part 2 switch the computing flag alternately to share the memory. Since an arithmetic processing can be completed within prescribed time when the slave CPU 2 is operated normally, the computing flag is always set at an off-state when a computation managing task is started up. In such a way, since the computing flag remains at the on-state when the abnormality occurs in the slave CPU 2, it can be decided whether or not the abnormality occurs in the slave CPU 2 by checking the computing flag when the master CPU 1 starts up the computation managing task.

Title: Cream solder dispernser
Inventor: ATOU TAKAYOSHI
IPC: B23K3/06
Filed: 1990-07-18
Abstract: PURPOSE:To stabilize the amt. of cream solder by providing a feedback control system which compensates the pressure fluctuation of an air pressure supply source and subjects the secondary side pressure of a pressure regulator to control with fixed set-point to a set pressure in a pneumatic pipeline. CONSTITUTION:An electropneumatic regulator (to regulate the setter of the secondary pressure in correspondence to the electric signal from the outside, more specifically an impressed voltage) is adopted for the pressure regulator 7. The feedback system takes the detected value of the pressure sensor 12 detected on the secondary side of the pneumatic pipeline 8 on the downstream of the pressure regulator as a feedback signal into a controller 5. The controller compares the feedback signal and the set pressure valve and applies the control signal corresponding to this deviation to the pressure regulator 7, thereby making the control with fixed set-point of the secondary side pressure to the set pressure. The casual main pressure fluctuation of the air pressure supply source 9 is compensated in this way and the air pressure to be introduced into a syringe 1 is maintained always under a prescribed pressure. The discharge rate of the cream solder supplied onto printed wirings from the syringe is stabilized and the reflow soldering of electronic parts is executed in a normal state.

Title: Automatic working condition deciding device
Inventor: YONEDA TAKAO
IPC: B23Q15/00
Filed: 1990-07-17
Abstract: PURPOSE:To automatically decide the optimum working condition even by a worker who is not an expert by correcting a relational internal constant corresponding to the correction of the working condition by the experience or intuition of the worker, correcting the weight of a neural network based on the internal constant, and affecting a result on following correction. CONSTITUTION:The working conditions such as working sequence, the rotating speed of a workpiece, and machining allowance, etc., are found from data stored in an attribute data storage main spindle 332 and the internal constant by a working condition arithmetic main spindle 31. When the working condition is corrected by an internal constant correction means 31, the relational internal constant is corrected corresponding to the correction value of the working condition. The weight of the neural network 31 is corrected so as to obtain the internal constant corrected by the internal constant correction means 31 for the same input before correction by a weight correction means 31. In such a way, since a corrected internal condition is applied by correcting the internal constant of the neural network 31 at every correction of the working condition, a desirable working condition can be derived. Thereby, it is possible to obtain the optimum working condition even by the worker who is not the expert.

Filed: 1988-08-01
Abstract: PURPOSE:To reduce the resistivity of a machining solution for carrying out machining with a desirable resistivity by constituting so that machining solution supply control valve is driven by the detected output from a resistivity detector so as to supply city water to a machining liquid tank. CONSTITUTION:After the machining of a workpiece made of copper, supersteel, or the like has been completed, when the set value of a resistivity detector having been made up of a detection electrode 4 and a meter relay 11 is lowered on purpose to machine workpiece made of SK material or the like, the resistivity of the machining solution is greater than the set value.

As a result, the resistivity of the machining solution is gradually decreased, and when it becomes less than a set value, the output from the resistivity detector disappears to stop the drive of the solenoid valve 10, and the supply of city water is stopped, and the resistivity of the machining solution is maintained at the set value.
