Title: Monitor device
Inventor: SAKAI TAKAMI
IPC: G05B23/02
Filed: 1982-02-05
Abstract: PURPOSE:To detect an abnormal input signal with high accuracy, by providing a function to that no change of state is produced for a period longer than a perscribed time after detecting the discordance between two signals to a device that supplies and integrate plural pulse signals. CONSTITUTION:Input signals UA-UC are supplied to one side of each of OR elements 12-14, and the output of these OR elements are supplied to AND elements 15-17 and an OR element 18 which form a 2-out-of-3 circuit. The discordance detecting circuits 20-22 deliver 1 when the pulses are not coincident with each other. Times 35-40 delivers a pulse 1 when the pulse feeds 1 for a period longer than the prescribed time. The circuits 20 and 22 are set at output 1 along with the output of an AND 25 and a timer 35 set at 1 when pulses UB and UC are set at 0 with only pulse UA kept at 1. Then an AND28 and an OR34 deliver 1 to set an FF49. Thus the pulse UA is decided faulty. A similar operation is carried out when pulses UB and UC are set at 1 with only pulse UA kept  at 0. It is also decided that the pulse UA is faulty. In such a way, a fault of an  input signal is detected with high accuracy.

Title: Structure for illuminating criterion displaying section of clock
Inventor: HASEGAWA NAOKI
IPC: G04B19/30
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To make criterion displays easily distinguishable even when the displays are closely arranged to a face by efficiently illuminating the displays from the front sides by illuminating the displays by attaching an EL plate having notches suitable to display windows to the back of the face. SOLUTION: At nearly the center of an EL plate 12, notches are formed suitably to the display windows 2a of a face 2. When the EL plate 12 attached to the back of the face 2 emits light, the light from the EL plate 12 is projected upon and irradiates criterion displays 6a and 8a at displaying positions from the front sides of criterion displaying plates 6 and 8. Since the displays 6a and 8a at the displaying positions are irradiated with the light from the annular EL plate 12 from the peripheral side, the entire parts of the displays 6a and 8a which can be seen through the two display windows 2a of the face 2 are evenly irradiated with a sufficient quantity of light in a very easily distinguishable state without shadow, etc., and the displays 6a and 8a can be illuminated efficiently.

IPC: H02P6/21
Filed: 1991-02-13
Abstract: PURPOSE:To realize smooth transition of mode in a short time by lowering acceleration rate for a predetermined time immediately before transition from synchronous operation mode to rotor position detecting operation mode. CONSTITUTION:Under rotor position detecting operation mode, voltage signals U-W induced in the armature winding 4 of a brushless motor 3 having a magnet rotor 5 are detected and converted through a rotor position detecting means 6 thus obtaining rotor position detection signals 6U-6W. A motor 3 is operated based on produced commutation signals 7U-7W. Under synchronous operation mode, a rotary field is generated based on commutation signals created from external signals before the signals 6U-6W are established thus operating and accelerating the motor 3 forcibly. Acceleration rate in the synchronous operation is lowered during a predetermined interval immediately before transition from the synchronous operation mode to the rotor position detecting operation mode thus accelerating the motor slowly. According to the invention, the rotor position detection signal is established stably thus bringing about a state sufficient for mode transition.
