Title: Keyboard switching system
Inventor: SHIBUYA TOSHIKI
IPC: H03M11/04
Filed: 1989-03-31
Abstract: PURPOSE:To arbitrarily switch a keyboard without interrupting work by resetting not the whole system but only a part related to a keyboard when the keyboard is switched, and preserving the contents of a memory to be erased at such a time to the other area of the memory beforehand. CONSTITUTION:In the state of command waiting in an operating system, a keyboard switching item is selected on a menu screen. To prepare for the resetting of system information in the memory, information related to the keyboard is stored into the idle area of the memory. The switch of the keyboard is changed over, a CPU 21 initializes the keyboard information in a RAM area 22-1, and resets the keyboard. When a reset code returned from the keyboard is not confirmed, the CPU judges that the keyboard has not been switched, and restores the stored information related to the keyboard to an original position. Thus the keyboard can be switched even during the system operation.

Title: Supporting device of filter cloth in automatic filter press
Inventor: SUZUKI AKITOSHI
IPC: B01D25/12
Filed: 1983-05-11
Abstract: PURPOSE:To discharge smoothly and uniformly cakes by suspending a filter cloth hanging rod from a pulley through a spring on a hanger rail provided in the moving direction of the filter cloth. CONSTITUTION:After finishing filtration, a presser plunger 8 is moved backward to move a clamping plate 7 and a filter plate 1. Since the filter cloth is supported by a filter cloth hanging rod 14 which is suspended from a pulley 16 on a hanger rail 15 through a spring 17, the part 11a of the filter cloth at the upper part of the filter plate 1 is stretched due to the movement of the filter plate 1, and the pulley 16 is moved thereby. Since the length of the parts 11a and 11b of the filter cloth is equal, the filter cloth hanging rod 14 is kept midway between two filter plates 1. When the filter plate 1 is further moved and the tensile strength of the spring 17 exceeds the adhesive force between each filter cloth 11 and the filter plate 1, the stripping of the parts 11a and 11b of the filter cloth from the filter plate 1 may be advanced. In this case, however, due to the buffering action of the spring 17 and the movement of the pulley 16, the filter cloth hanging rod is always kept midway between the two filter plates 1, and the cake is easily discharged.
