Title: Rotational angle detector
Inventor: MIZUSHIMA MASASHI
IPC: G01C9/18
Filed: 1989-12-27
Abstract: PURPOSE:To make an apparatus simple in structure, compact in size and low in cost by providing a doughnut-shaped conductive body and a nearly doughnut- shaped resistance body confronting coaxially to the conductive body and with a part removed. CONSTITUTION:A nearly doughnut-shaped resistance body 12 is placed coaxially confronting a doughnut-shaped conductive body 11. A part of the resistance body 12 is cut, thereby forming a gap. The conductive body 11 and resistance body 12 are coupled at the outer peripheries thereof by an outer spacer 13. Moreover, the conductive body 11 and resistance body 12 are coupled at the inner peripheries thereof by an inner spacer 14. Accordingly, a ring-like space is defined between the conductive body 11 and resistance body 12, into which mercury 15 is sealed. Further, an end of an electric wire 17 is connected to the conductive body 11, while an end of an electric wire 16 is connected to an end of the resistance body 12. When the cutting part of the resistance body 12 is set upward to the gravity, the mercury 15 comes down. As the apparatus is rotated around its rotary shaft, the mercury 15 is relatively moved, thereby changing the resistance value. As a result of this, the rotational angle can be detected.

Title: Trap processing method
Inventor: GUEN RE TORON
IPC: G06F9/38
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent the delay for protecting the contents of registers by calling an exception handler when an instruction includes a synchronism exception before the specific execution time of a prefetch instruction. SOLUTION: When a software trap instruction is detected by a CF-DET unit, the internal exception mark bit in an instruction logic unit which corresponds to the instruction is set and a software trap number is stored corresponding to the trap instruction. An IFU 102 prefetches and puts a trap handler in an MBU lower instruction stream buffer and a logic unit sends the exception mark bit of the instruction set to an IEU 104 and reports which instruction in the instruction set is already judged to be the generation source of the synchronism exception in such a case. The IEU 104 does not respond immediately and all the instructions in the instruction set are scheduled by an ordinary method.

Abstract: PURPOSE: To prevent the backlash between a shift and a bearing without increasing the number of parts and to improve the productivity without complicating the structure of a motor by forming an energyzing means, which energizes the shaft in the lateral direction with respect to the axial direction, as a unitary body in a bracket. CONSTITUTION: A slant part 10 is formed as a unitary body in a bracket 2 as an energizing means, which energizes a shaft 4 in the lateral direction with respect to the axial direction of the shaft. A part of the bracket 2, with which the base end part of the shaft 4 is in contact, is not flat as in the conventional motor but is inclined. In this constitution, a force F1, which pushes the bracket 2 in the axial direction by the effect of the thrust suction force, acts by the contact of the base end part of the shaft 4 of a motor M to the slant part 10 of the bracket 2. At the same time, a force F2 in the radial direction of the motor M acts. The shaft 4 is energized in the lateral direction by the action of the force F2. Therefore, the backlash between the shaft 4 and the bearing 3 can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To suppress the prolongation of device occupation time by storing retrieving sheet unoutput information and stopping the printing processing of a retrieving sheet when printing cancel for the sheet is specified. SOLUTION: When printing processing does not end yet, the stop of printing due to the depression of a stop key is judged, and when the stop key is depressed, retrieving sheet unoutput information indicating the unprinting of a retrieving sheet is generated and stored in a magneto-optical disk and the printing processing of the sheet is stopped.

At this time, the number of unprinted retrieving sheets is simultaneously displayed. When paper is fed during the display of the alarm, the operation picture is switched. When a cancel key 1171 on the operation picture is depressed, the image data of a prepared retrieving sheet are invalidated, retrieving sheet unoutput information is stored and the printing processing of the retrieving sheet is stopped.
