Title: Magnification switching controller
Inventor: HONDA YOSHITAKA
IPC: G03G15/00
Filed: 1990-02-27
Abstract: PURPOSE:To prevent the switching of an optical system caused by an misoperation by displaying a magnification and simultaneously starting the count of a time set in advance, when the magnification is selected by a selective operating part, and switching the optical system according to the selected magnification when a counted period is finished. CONSTITUTION:A timer 12 starting to count the time set in advance in response to the operation of a magnification changeover switch 2 for selecting the magnification display is provided. A microcomputer 11 switches only the magnification of a magnification display part 7 to the selected magnification in response to the operation of the magnification changeover switch 2. When the counted period is finished, an optical system driving mechanism 10 is controlled so that the lens and mirror of the optical system are moved to a position corresponding to the magnification, and simultaneously, a clutch, etc., are switched so as to obtain scanning speed corresponding to the magnification. Thus, the switching of the optical system caused by the misoperation can be prevented.

IPC: H02P29/00
Filed: 1989-02-28
Abstract: PURPOSE:To facilitate the generation of a track of a target velocity value that can be easily followed by adding together the target velocity value applied to the present output of a data generation part and the target velocity value applied to the output preceding by a prescribed time and stored in a memory part for production of the target value accordant with a new track. CONSTITUTION:A data generation part 13 generates the target value accordant with a prescribed track 17 for each sampling cycle and outputs it. The target velocity value accordant with a track 18 and preceding by a prescribed time is read out of a memory part 14, and the target velocity value applied to the reading operation is driven out of the part 14. Then the new target velocity value applied to the present output of the part 13 is written into the part 14. These two target velocity values are added together via an adder 15 and divided by two via a divider 16. Thus the target velocity value accordant with a new track 19 is obtained.

Title: Remelting method for printed board
Inventor: BERUNHARUTO BURABEETSU
IPC: H05K3/22
Filed: 1989-02-28
Abstract: PURPOSE: To prevent a printed board from being damaged by a thermal load by performing a remelting process under high gas peripheral pressure in a high-pressure vessel and supplying the quantity of heat required for remelting through a temperature- controlled oil bath, etc. CONSTITUTION: In a method for remelting a tin or tin-lead electroplated film on a printed board, an oil bath is prepared by containing remelting oil maintained at, for example, 215 deg.C in a pressure vessel, and the temperature of the remelting oil is maintained at the fixed value with a controlled heating system. Then the printed board to be remelted is positioned on the remelting bath. The pressure of a nitrogen gas contained in the pressure vessel is adjusted so that the pressure can become, for example, 18 bars when the temperature of the nitrogen gas is at 60 deg.C. When the desired pressure has been obtained, the printed board to be processed is sunk in the oil bath and maintained in the bath for about 30 seconds. While the printed board is being maintained in the bath, a remelting process is performed in the oil.  After the remelting process, the printed board is taken out of the oil bath and cooled to the room temperature in the pressure vessel. After cooling, the pressure of the nitrogen gas is lowered to atmospheric pressure, and the treated printed board is taken out of the pressure vessel.
