IPC: B60K28/00
Filed: 1979-06-13
Abstract: PURPOSE: To give adequate alarm to the driver by requesting the driver for response only at the time of monotonous driving which has a possibility of causing a driver to fall into a lowered state of the awakening degree and detecting the awakening degree of the driver from whether the response time is appropriate or not.  
     CONSTITUTION: In a monotonous driving detecting circuit 1, when the shift lever is at a 4-speed position or 5-speed position, a shift switch 14 is turned on, the output from the circuit 1 is supplied through an integrated circuit 16 to a comparator 19 and is compared with a constant voltage V. When the output has reached the voltage V, a monotonous drive signal is produced as output. When a preliminary alarm is generated by this signal, a monostable multivibrator circuit 21a is turned on over a time t. In this case, when the driver depresses a reset switch 20 after the lapse of a certain delay time, a switch 24a is interrupted by the switch 20 if the response is within the time t. However, when the response of the driver is delayed and the response is made after the lapse of the time t, the circuit 23 is turned on, and the switch 24b is turned on to actuate the alarming circuit 5.

Abstract: PURPOSE:To discharge completely recording paper which can be discharged by stopping a driving system automatically when a conveyance accident of recording paper occurs to a recording device, and discharging recording paper in a fixing and discharging device and then stopping the discharging device automatically. CONSTITUTION:When a sensor S2 detects no recording paper even at the prescribed time of a timer 1, the sensor detects the occurrence of the conveyance accident, i.e. jamming of a discharging-out roller 6. When the sensor S2 detects recording paper before the prescribed time of the timer 1, the timer 1 turns off at the point of time and a timer 2 turns on instead. If no recording paper is detected even at the prescribed time of the timer 2 after the sensor 2 detects said recording paper, the occurrence of a jam near a register roller 7 is detected and similarly when a sensor 3 detects recording paper, the state of such a jam that the recording paper is still wound around the photosensitive drum 2 without being separated and deviates from a normal conveyance path is detected. If some of the sensors S1-S3 detects a jam, a motor M2 is stopped after the conveyance of recording paper being conveyed is completed.

Abstract: PROBLEM TO BE SOLVED: To realize a rotating machine with a high power factor and high efficiency, as preventing the reductions of the main magnetic fluxes of its permanent magnets which are related to its output power, and reducing its q axis inductance, by forming its rotor out of a core with non-magnetic portions provided along the center axes of its respective magnetic poles and out of a non-magnetic rotational shaft. SOLUTION: Disposing four NdFeB permanent magnets 12 constituting magnetic poles on the surface of a rotor core 13 made of such a magnetic material as a laminated silicon steel plate, four non-magnetic materials 14 of SUS 304, etc., are buried in the rotor core 13 along the center axes of the respective magnetic poles to form a rotor. Further, a rotational shaft 15 made of the non-magnetic material of SUS 304 is joined to the rotor core 13, thereby dividing the rotor core 13 magnetically into four portions by the non-magnetic portions 14.

CONSTITUTION:A first conductivity type fourth layer (N-layer 3) is formed in a third layer (P-layer 4) is formed in a third layer (P-layer 3) to interconnect the third layer 3 and the fourth layer 4, and an insulating gate electrode G is disposed on a surface of the third layer 3 between a first layer 1 and the fourth layer 4 through an insulating layer 5. Accordingly, a parasitic MOSFET is formed, which includes the fourth layer 4 as a source region, the third layer 3 as a base region, the insulating gate G as a gate region, and the surface of the third layer located under the insulating gate G as a channel region. Additionally, the shortest distance (magnitude of the nearest part 7) in the third layer, which is an important parameter providing a normal off-characteristic can be determined independently from a distance between surfaces of the third layer. Hereby, the width of the first electrode K and a distance between the first electrode K and the insulating gate electrode G can be increased regardless of the normal off-characteristic to provide redundancy to dimensional accuracy and hence improve productivity.
