摘要:
An electric motor control unit mounted in an automotive vehicle having a motor that is variable in its rotational speed. A temperature sensing element is arranged to contact a busbar so that relays permit switching operation in response to detection of abnormal heat generation. This controls an electrical power supply to the motor to decrease the rotational speed of the motor without complete stopping of the motor. The rotational speed of the motor returns to a normal speed from the decreased speed by switching operation of the relays with diminishing of the abnormal heat generation.

A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device is configured to emit a movement notification sound to an outside of a vehicle to inform a person in an area surrounding the vehicle that the vehicle will move. The notification sound control device is configured to operate the sound emitting device in response to occurrence of a vehicle condition. The notification sound control device setting the movement notification sound of the sound emitting device to a frequency in a range of 1.5 kHz to 6 kHz.

A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits a starting movement notification sound to outside of a vehicle to inform a person in an outside area surrounding the vehicle that the vehicle will transition from a stopped state to a moving state, and emits a moving notification sound to outside of the vehicle to inform a person in the outside area surrounding the vehicle that the vehicle is moving. The notification sound control device operates the sound emitting device to selectively emit the starting movement notification sound. The notification sound control device includes a notification sound emission timing section that sets a start timing of the starting movement notification sound in response to a shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed.

The method of producing a thin film magnetic head from a raw bar, in which a plurality of combinations of a thin film magnetic head including a reproducing head and an ELG element are continuously formed, comprises the steps of: measuring resistance of a magnetoresistance effect element section of each ELG element as first resistance; measuring resistance of a magnetoresistance effect element section of each thin film magnetic head as second resistance; detecting existence or nonexistence of a smear in an air bearing surface of each thin film magnetic head on the basis of the difference between the first resistance and the second resistance; and removing the smear from only the thin film magnetic head in which the existence of the smear is detected.
摘要:
Validation of an input protocol is divided into two steps. In the first processing step, a state. transition graph of each process including only executable state transitions of each process is generated according to transition information which the protocol specification has, and at the same time, protocol errors related to behavior of the process is detected. In the second processing step, reachable system states among system states defined by combinations of individual process states and individual channel states are successively generated according to transition information which the state transition graph of each process has, and a system state of the generated reachable system states which cannot transit further is detected as a deadlock. In the protocol validation method, every system state can be erased from the memory when a deadlock detection for it is completed, and searching the generated system states is not necessary, and some additional techniques for more efficient validation can be applied. Therefore the protocol validation method enables validation with a practical period of time even for a large-scale or complicated protocol specification without requiring a large-capacity memory.

A vehicle notification sound emitting apparatus is basically provided with a first sound emitting device, a second sound emitting device and a notification sound control device. The first sound emitting device emits a first intermittent notification sound inside a cabin interior of a vehicle. The second sound emitting device emits a second intermittent notification sound outside of the cabin interior of the vehicle. The notification sound control device operates the first and second sound emitting devices to separately emit the first and second intermittent notification sounds in at least a partially overlapping pattern in response to occurrence of a vehicle condition to convey a same type of vehicle information to both inside and outside of the cabin interior of the vehicle. The notification sound control device includes a cabin interior-exterior notification sound synchronizing section that is configured to synchronize the first and second intermittent notification sounds.

A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits forward and reverse advancement notification sounds outside of a vehicle to inform a person in an area surrounding the vehicle that the vehicle will move. The notification sound control device operates the sound emitting device to selectively emit the forward and reverse movement notifications. The notification sound control device includes forward and reverse advancement notification sound emission timing sections. A start timing of the forward advancement notification sound is set in response to both a forward movement shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed. A start timing of the reverse movement notification sound is set to be emitted immediately in response to the reverse movement shift operation having been performed.

An electrical load drive control apparatus includes: a plurality of drive units, each of which drives one of a plurality of electrical loads; an instruction unit that issues a drive switch instruction to switch drive among the plurality of electrical loads; a detection unit that detects a non-operating state of the plurality of electrical loads; and a control unit that controls the plurality of drive units based upon the drive switch instruction issued by the instruction unit and results of a detection by the detection unit. And the control unit controls the plurality of drive units so as to set all of the plurality of electrical loads in a non-operating state if an instruction to switch drive among the plurality of electrical loads is issued by the instruction unit, and controls the plurality of drive units so as to switch drive to an electrical load selected through the drive switch instruction after verifying that the plurality of electrical loads are all set in a non-operating state based upon the results of the detection by the detection unit.
摘要:
Two motor fans are driven by two 4-pole direct current motors, respectively. Rotational speed of the two motors is controlled in three stages, namely low speed, intermediate speed and high speed. Specifically, at the time of low speed operation the two motors are connected in series with four poles, at the time of intermediate speed operation the two motors are connected in parallel with three poles, and at the time of high speed operation the two motors are connected in parallel with four poles.
