Title: Step-out preventive system for step motor
Inventor: TAKAHASHI KIYOSHI
IPC: F23N1/00
Filed: 1992-01-28
Abstract: PURPOSE:To make it possible to prevent step-one by interrupting the output of driving pulse from a microcomputer to a step motor during instantaneous voltage drop occurring in the main power supply circuit for step motor. CONSTITUTION:If the voltage drops below a predetermined level in a main power supply circuit 28 for step motor when a microcomputer 24 is driving a step motor 4, an instantaneous voltage drop detecting circuit 30 delivers a LOW signal 34 to an input port 21 of the microcomputer 24 for detecting instantaneous voltage drop. During a time when the microcomputer 24 recognizes the instantaneous voltage drop, the output of driving pulse from an output port 20 to the motor 4 is interrupted thus stopping actual rotation of the motor 4. When the voltage of the main power supply circuit 28 is reset to a normal level, the output of driving pulse is resumed thus resuming actual rotation of the motor 4. Consequently, the number of rotational steps of the motor 4 counted through the microcomputer 24 matches at all times with the actual number of rotational steps of the motor 4.

IPC: B66B29/08
Filed: 1994-03-09
Abstract: PURPOSE:To shorten waiting time for the arrival of a wheelchair step at a landing by providing a driving control means for moving the wheelchair step into the position of a get-on side landing in the shorter direction of moving time obtained by a moving time computing means on the basis of the position information of the wheelchair step detected by a position detecting means. CONSTITUTION:Upon sensing any one of objects to be sensed by an optical sensor, the optical sensor detects its identification code and inputs it as a position detection signal (k) to a microcomputer 36 of an operation control circuit 30. The microcomputer 36 indexes the present position of a wheelchair step on the basis of the received position detection signal (k), computes time needed in the case of moving a motor 9 in the normal rotating direction and time needed in the case of moving the motor 9 in the reverse rotating direction to move the wheelchair step from the present position to a landing on the lower floor, and judges the shorter rotating direction to move the wheelchair step into a get-on position. The time needed before a wheelchair gets on the wheelchair step can be thereby shortened.

Title: Instruction division processing system
Inventor: KANEDA HIROYUKI
IPC: G06F9/38
Filed: 1985-02-28
Abstract: PURPOSE:To perform processing in a high speed with a simple control by changing the sequence of instruction execution according as all elements required for execution of instructions are read out from a storage device or not. CONSTITUTION:If 4* of an instruction 1 exists in the following page, the processing is interrupted temporarily, and the processing is restarted after mak ing it possible to read 4*. Since the processing precedes with respect to already read-in 0*-3*, the processing is completed up to a cycle 1. When it is detected that 4* exists in the following page, internal states are saved for the purpose of starting the condition meeting processing, and internal states are restored after the condition meeting processing to restart the processing from a cycle 2. Thus, the processing of the instruction can be executed though two pages of virtual memory do not exist simultaneously on an actual memory. If elements are read in time for the cycle of the execution, the instruction is executed though all elements of one instruction are completed.

Filed: 1995-02-04
Abstract: PURPOSE: To attain automatic dialing to a desired telephone number with a simple operation during speech. CONSTITUTION: When a call button and a dial button '2' are depressed while a receiver 1 is hooked off during speech, a control microcomputer 21 applies on-hook control to a hook switch circuit 8 to interrupt a line once and then applies off-hook control to close again the line and dials a contract telephone number of a pocket beeper registered in a 2nd registration area of a RAM 22. When a reply detection circuit 13 detects a reply of a destination, the control microcomputer 21 sends transmission information 51# registered in the 2nd registration area and applies on-hook control to the hook switch circuit 8 to interrupt the line.  Thus, calling of the pocket beeper and message transmission are conducted automatically, and then troublesome operation such that the user hooks on the receiver 1 at once, hooks off the receiver, dials the contract telephone number and message information and then hooks on the receiver 1 again is avoided.
