摘要： PURPOSE:To make movement of a sun visor performable automatically and so calmly, by operating a driving member composed of a form memory alloy at a time when an optical sensor detects incidence of the sunlight, and constituting the sunvisor so as to be moved to the specified position. CONSTITUTION:This sun visor has a body 1 to be attached to a ceiling closely to a boundary of a windshield, and inside the body 1, there is a curved surface- form visor 14 retractable from the front opening part 1a. And, when an insolation sensor detects incidence of the sunlight, a coil-like form memory alloy 12 is energized with a current, coming into self-heating, being compressed and deformed, therefore a wire 24 is pulled against a spring 13 and a drive roller 4 is rotated, thus the visor 14 locked to a visor holder 11 is constituted so as to be projected frontward from a case 1. And, when this projection completion of the visor 14 is detected by a position sensor 10, the form memory alloy 12 is controlled to be energized to a current value with which the visor 14 is kept up in a projected state.

摘要： PURPOSE:To enable highly-precise measurement of the quantity of heat received by a vehicle, together with the angle of elevation and the azimuth angle of solar radiation, by a method wherein the sum vector of the respective normal vectors of the light-sensing surfaces of three light-sensing elements is made to accord substantially with the direction of the solar radiation wherein the quantity of heat received by the vehicle is the maximum. CONSTITUTION:A sensor 1 comprises a first light-sensing element Sa facing upward, a second light-sensing element Sb and a third light-sensing element Sc inclined forward by the same angle in the direction of the traveling of a vehicle C and having light-sensing surfaces inclined symmetrically in the lateral direction to the direction of advance of the vehicle C, and a means of adding up outputs of the light-sensing elements Sa to Sc. It is so disposed that the sum vector of the respective normal vectors of the light-sensing surfaces of the three light-sensing elements Sa to Sc accords substantially with the direction of solar radiation wherein the quantity of heat received by the vehicle C is maximum. Accordingly, the sum of the outputs of the light-sensing elements Sa to Sc becomes the maximum value when the solar radiation comes from the direction indicated by the sum vector of the respective normal vectors of the light-sensing surfaces. As the result, the characteristic of the sum of the outputs of the light-sensing elements Sa and Sc in regard to the direction of the solar radiation can be made to accord with the characteristic of the quantity of heat received by the vehicle C in regard to the direction of the solar radiation, and thus execution of highly precise measurement is enabled.

摘要： PURPOSE:To reduce pressure hunting without deteriorating an acceleration character by providing a check valve type regulating valve, having a function of throttling a high pressure from a high pressure introducing passage, in a signal pressure passage for guiding the high pressure to a control pressure chamber through the high pressure introducing passage. CONSTITUTION:A check valve type regulating valve, having a function of throttling a high pressure supplied from a high pressure introducing passage 96, is provided in a signal pressure passage 98 for guiding the high pressure to a control pressure chamber 200, formed in the back surface of a spool 30, through the high pressure introducing passage 96. By this constitution, in the case of introducing the high pressure to the control pressure chamber 200, formed in the back surface of the spool 30, through the high pressure introducing passage 96, a flow amount can be limited by throttling action of the check valve type regulating valve with reduction made possible of pressure hunting. Further in the case of transfer to a low displacement, because no throttling action is performed by the check valve type regulating valve, the transfer is promptly performed to the low displacement without deteriorating an acceleration character.

摘要： PURPOSE:To sensitively detect a change of sensible temperature by air flow and enhance the comfortableness of air conditioning by determining wind velocity on the basis of radiating temperature at the time of electrification and environmental temperature at the time of non-electrification, and determining the sensible temperature of a passenger from the wind velocity and environmental temperature to correct and control the temperature of the discharged air. CONSTITUTION:When the air flow from a blowout hole 13 flows toward the face part of a driver D and a sensible sensor 140 at the time of blow-up mode, the electrification of a heater is conducted by microcomputer control, the radiating temperature is detected, thereafter, the electrification is cut, and the environmental temperature is detected. On the basis of the radiating temperature and environmental temperature, a wind velocity V is calculated by a determined expression. According to the wind velocity V, the face temperature of the driver D is calculated. According to the face temperature and a target face temperature, a corrected blow-off temperature is successively calculated, and the air flow is blown out into a vehicle chamber 10a at this blow-off temperature. Thus, the air conditioning in the vehicle chamber 10a under blow-up mode can be properly realized while ensuring the air conditioning corresponding to the sense of heat of the face part of the driver D.

摘要： PURPOSE:To judge accurately disorder of a living body by determine peaks of strength in the pulsation wave frequency of near 0.1 and 0.2-0.4 beat based on the spectral distribution data and judging disorder corresponding the decrease in the degree of arousal of the living body in accordance with them. CONSTITUTION:When a driver starts driving and running a vehicle, a light from a luminescent diode 13a is entered in an earlobe by the driving of a light emitting driving circuit 20 and a reflected light caused by a blood flow is received by a phototransistor 13. It is changed to a pulsation wave signal, which is input in a microcomputer 40 through an amplifier 31, a filter 32 and an A/D transducer 33. The microcomputer 40 calculates successively a period of each detected pulsation wave and obtains a spectral distribution data of the frequency and the strength of the pulsation wave based on the analysis of the frequency. It determines peak values of strength in the pulsation wave frequency of near 0.1 and 0.2-0.4 beat and judges possibility of disorder corresponding to the decrease in the degree of arousal of the living body in accordance with both peak values. If the presence of disorder is judged, a buzzer 52 is actuated. Disorder of the living body can be judged thereby with good accuracy.

摘要： PURPOSE:To ensure visibility effectively by making a liquid crystal panel drivable at a tertiary light permeability factor between glare shield and non- glare shield conditions and changing over the panel to the non-glare shield condition in a predetermined time when the panel is driven at the tertiary permeability factor. CONSTITUTION:When a vehicle is running, light intensity on a sensor 1 fitted to the front of a body is measured and evaluated by the CPU 2b of a controller 2. And when output from the sensor 1 has exceeded a threshold value Th2, a liquid crystal sun visor 3 is changed over to a glare shield condition via a drive circuit 2c. When said output is below a threshold value Th1, the sun visor 3 is changed over to a non-glare shield condition 3a. On the other hand, when said output is between the two threshold values Th1 and Th2, the sun visor 3 is changed over to an intermediate condition (tertiary light permeability factor) via the drive circuit 2c. And in this intermediate condition, the sun visor 3 is so controlled as to be changed over to the non-glare shield condition in a predetermined time (about 5sec).
