Filed: 1991-12-17
Abstract: PURPOSE:To facilitate the detection of a common bus stack fault by releasing the clogging of a switch when the bus pull-in switch comes to a clogged state at the time of turning on power and when diagnosis is executed. CONSTITUTION:When the power of a system is turned off owing to a fault and a signal turning on power for diagnosis is inputted to a bus control part 4, a diagnosed device 2 sets the bus pull-in switch 3 in the clogged state from the bus control part 4. Thus, a switch contact point (a) connected to a common bus 1 is connected to the side of a contact point (c) on a clogged-side. When a signal for releasing clogging is supplied from a system supervisory device 5 to the diagnosed device 2, the bus control part 4 gives the signal for releasing clogging to the bus pull-in switch 3. Thus, the bus pull-in switch is changed over and the contact point on the common bus-side is connected to the contact point (b) on an internal bus-side. Thus, the common bus 1 comes to the connection state with the internal part of the diagnosed device 2 and a diagnosis operation is executed.

Title: Operation control device for air conditioner
Inventor: OKAMURA YUKIO
IPC: F24F11/02
Filed: 1988-12-29
Abstract: PURPOSE:To enable an operation control of a ventilation fan to be carried out in cooperation with an operation of an air conditioner by a method wherein a compressor is operated in response to a difference from a set value of a room temperature, either a cooling or a heating capability is generated, and the ventilation fan is operated only when a temperature difference between a surrounding air temperature and the room temperature is contributable to the cooling or heating operation. CONSTITUTION:For example, in case of performing a cooling operation, at first an indoor air blower 12 and an outdoor air blower 12 are operated, air is fed to a room temperature sensing thermistor 7 and a surrounding air sensing thermistor 17, thereby an operation preparation is carried out. In case that a room temperature is lower than a predetermined value, a compressor 13 and a ventilation fan 3 are not operated due to the fact that outputs from the micro-computers 24 and 33 to the driving transistors 22 and 31 become 'LO', and in turn in case that the room temperature is higher than the predetermined value, an ON signal from the micro-computer 24 is transmitted to the micro-computer 33 in the same manner as above and 'HI' is outputted to the driving transistor 31, resulting in that the compressor 13 is operated to perform a cooling operation. Then, in case that the surrounding air temperature is lower than the room temperature, 'HI' is outputted from the micro-computer 24 to the driving transistor 22, resulting in that the ventilation fan 3 may start its operation.

Title: Automatic adjuster for vehicular headlight optic axial direction
Inventor: OKUCHI HIROAKI
IPC: B60Q1/076
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To get rid of any inaccurate optic axial direction control of a headlight according to a vehicle traveling state. SOLUTION: A pitch angle in the longitudinal direction of a car is calculated on the basis of each signal out of two height sensors 11F and 11R installed both front and rear wheels of the car. In addition, a vehicle traveling state is in any of control modes among stoppage, acceleration, deceleration and constant speed, and whether it is the initial state or not is judged from car speed and acceleration based on it. The pitch angle is filtered in response to this control mode and an actuator desired value (target optic axial direction adjusting angle), ungiving any dazzling light to the opposite car, is calculated, therefore both actuators 30L and 30R are driven and each optic axial direction of headlights 30L and 30R is adjusted.  Thus, since proper filter processing takes place for the pitch angle, any optic axial direction control of the unnecessary headlight due to road surface irregularities is preventable.
