Title: Repetitive instruction processing device
Inventor: MORISHIMA KIYOSHI
IPC: G06F9/32
Filed: 1982-12-27
Abstract: PURPOSE:To execute continuously and incessantly repetitive instructions and object instructions and to improve its performance by providing an operand address buffer and writing operand addresses in an index register quickly. CONSTITUTION:Writing of each register is performed by an instruction starting signal in a controlling circuit 30. Repetitive instructions and objective instructions are on condition that repetition is completed depending on the result of operation of repeated objective instructions. For instance, when a detecting circuit 10 detects that the condition of completion is satisfied by the third repetition, the circuit 10 sets a flag. Accordingly, writing signals to registers 4, 5, 14, 15, 1, 17 and a buffer 18 are suppressed. The register 1 holds the result of the third repetition, and the address of the buffer 18 is contained in the register 17. The controlling circuit 30 reads the third operand address of the contents of the buffer 18 designated by the register 17 and writes in an index register 2 through a selector circuit 8.

Title: Operation indicator for switchgear
Inventor: MUROI RYOICHI
IPC: H01H9/16
Filed: 1993-09-16
Abstract: PURPOSE:To simplify the structure while shortening the time required for assembling or adjusting by employing a release at a part for mechanically transmitting the movement of a movable body interlocked with the operation of a switchgear. CONSTITUTION:When a switchgear is closed, a movable body 4 is shifted to a position 4A. Consequently, the wires in releases 5A, 5B are pushed to the left thus transmitting the motion for pressing the movable parts 20, 30 of a counter 2 and an open/close indicator 3. The movable part 20 is rotated clockwise and the count increases in the counter 2. When the movable part 30 is pressed, the indicator 3 is displaced to a position 3A in parallel with a front panel 1 thus allowing read-out of the character 'ON' written on the surface thereof from the front panel 1 side. This constitution simplifies the structure and saves manpower required for assembling and adjustment.

Filed: 1986-09-30
Abstract: PURPOSE:To make it possible to evade that an emergent incoming call can not be connected because of a permanent loop by detecting a busy tone transmitted from an exchange and issuing an alarm when a telephone set is in the state of permanent loop.

Abstract: PURPOSE:To prevent registration and display of an abnormal picture by rotating and inverting picture data at every prescribed angle and performing recognizing processes on the rotated picture data whenever the picture data are rotated and inverted, and then, discriminating picture data having a high recognition rate as a normal picture. CONSTITUTION:Picture data fetched from a scanner 10 are converted into inverted, rotated, and overturned picture data by means of a picture processor 4 and stored in a memory 15 for recognition. A recognition processor 14 recognizes the picture data and compares recognition rates on each data and, as a result of the comparison, the picture having the highest recognition rate is discriminated an a normal picture. Therefore, even when an inverted or overturned picture or a picture of white or black paper is inputted at the time of picture registration and display, the abnormal picture is automatically detected and warning can be made for correction. Thus futile registration of an improper picture on a recording medium can be eliminated.
