摘要： PROBLEM TO BE SOLVED: To provide a seated occupant determination device for a vehicle seat, capable of correctly determining a seated occupant by exercising ingenuity on structure of a seating position of the seat and a seat base and using as few seat sensors as possible. SOLUTION: In the seat base M, respective doglegged link levers 50, 60 are provided on sections between respective front parts and respective rear parts of a seat rail 30 and a lower rail 40 on respective left sides. The respective doglegged link levers 50, 60 are provided on sections between respective front parts and respective rear parts of the seat rail 30 and the lower rail 40 on the respective right side. Respective seat sensors are provided on a boundary section between both lever parts constituting the respective link levers 50, 60. The respective seat sensors thereby detect a distortion amount of the respective link levers which elastically deform corresponding to the load from the seating position on the seat base, thus determining the seated occupant on the seat corresponding to the distortion amount detected by the respective seat sensors.

摘要： PROBLEM TO BE SOLVED: To reduce abnormal sound based on the break up or deformation of bubbles upon flowing of liquid into an outlet pipe. SOLUTION: A heat exchanger, in which tanks 13, 14 for assembling and distributing liquid are arranged at both ends of tubes 11, through the inside of which the liquid flows, and an outlet pipe 16 is connected to the outlet tank 14, is equipped with bubble guiding pipes 17, 22 for guiding bubbles in the liquid, which are taken into at the side of the inlet tank 13, to the downstream side in the flow of liquid of the opening 161 of the outlet tank 14 side in the outlet pipe 16. According to this method, the bubbles in the liquid are conducted to flow while bypassing the opening 161 of the outlet pipe 16 whereby the break up or deformation of the bubbles in the liquid inflow part of the outlet pipe 16, which becomes the cause of generation of big sound especially, can be avoided thereby permitting the suppression of generation of abnormal sound.

摘要： PROBLEM TO BE SOLVED: To lower the noise by restricting the vibration of an expansion valve and an evaporator. SOLUTION: In this expansion valve, a valve element 47 is displaced while sensing the overheating degree of the gas refrigerant on the outlet side of an evaporator 5 so as to adjust an opening area of a throttle passage hole 48. In this case, a buffer member 60 having the impact absorbing property is provided in a low-pressure side double-phase refrigerant passage 43 at a position opposite to the throttle passage hole 48. The low-pressure side double-phase refrigerant passed through the throttle passage 48 collides with the buffer member 60, and the exciting force by the collision is damaged by the buffer member 60, and thereafter, transmitted to a main body 41 of the expansion valve 4. With this structure, vibration of the expansion valve itself is restricted, and furthermore, vibration of a pipeline and the evaporator 5 connected to the expansion valve 4 can be restricted.

摘要： PROBLEM TO BE SOLVED: To generate friction damping between a gear and a pulley for timing belt, suppress the transmission of torque fluctuation to the gear as much as possible, and reduce tooth hitting sound of the gear by inserting thin plates accumulated between the gear connected with a fuel injection pump and the pulley for timing belt. SOLUTION: In a timing train system which transmits the rotation of a crank shaft of an engine to a cam shaft and auxiliary mechinery by combining a gear and a timing belt, several thin plates 400 are provided between a pulley 2 and the gear 3, attached to the pulley 2 and the gear 3 by using a bolt 12, and then are fixed to a rotary shaft 1 by using a bolt 11. At this time, a diameter of a mounting hole of the bolt 12 of the pulley 2 and the thin plates 400 is set to be slightly larger than a diameter of the bolt 12. When torque fluctuation occurs in a fuel injection pump and the fluctuation is transmitted to the gear 3 at the time of driving, friction is generated among the pulley 2 and the gear 3 and the thin plates 400 due to a clearance between the mounting hole and the bolt 12 to damp the torque fluctuation.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized EGT valve device with a high responsiveness. SOLUTION: When a current is carried to a solenoid part 13, a solenoid shaft 12 is pushed down to warp a reed valve 6D situated on a lower plate 6C, whereby the air of an atmospheric pressure chamber 9 is carried into a negative pressure chamber 8. Since a diaphragm part 6 is thus moved down by the differential pressure between both the chambers, and an EGR valve 4 is also moved down through a shaft 7, EGR gas quantity is reduced. The positions of the diaphragm part 6 and the EGR valve 4 can be quickly and used according to the change of the current-carrying quantity to the solenoid part 13. Further, since an air passage 5 is allowed to communicate with a space 17 through a hollow part 16, and the diameter of the EGR valve 4 is substantially equal to that of a piston 15, the force by the pressure difference between the EGR valve and the upper and lower surfaces of the piston is canceled. Therefore, the driving force to the valve 4 can be minimized even when the EGR gas quantity is increased, and the device can be miniaturized.

Further, an oil pressure is fed to the other pressure chamber 63 and other ports are intercommunicated in a similar manner described above. A plurality of the solenoid valves 5A-5C excited and operated according to the running state of a vehicle control the feed and discharge of an oil pressure to and from the pressure chambers 62 and 63 of the friction fastening elements C and B and the mechanical switching valve 6A.

摘要： PURPOSE:To tilt an edge part in the forward direction of a wiper blade without fail irrespective of the travel speed of a vehicle, by changing a tilt angle of the wiper blade to a glass surface separately in each case of outgoing and returning movements, and holding it rotatably to a wiper arm. CONSTITUTION:A wiper blade 4 is supported on a wiper arm 5 so as to cause its tilt angle to a windshield surface 2 differ in each case of outgoing and returning movements via a rotary supporting mechanism 20 so as to make the specified angle rotatable. Therefore, when the wiper blade 4 reciprocatively travels, there is produced frictional force between an edge part 7 of blade rubber 3 and the glass surface, whereby the rotary supporting mechanism 20 is turned round up to one side of rotation end points, and the wiper blade 4 is tilted to the forward direction side, thus the edge part 7 is tilted in the forward direction of the wiper blade 4. Therefore, an unwiped part and a chattering phenomenon due to air pressure to be produced at the time of car running are preventable.

摘要： PROBLEM TO BE SOLVED: To reduce noise generated when a large quantity of refrigerant flows through a passage hole. SOLUTION: Since the first passage 43a of a two-phase refrigerant passage 43 on the low pressure side is provided with a member 60 projecting toward a second passage 43b, significant pressure variation of refrigerant immediately after passing through a throttle passage hole 48 is damped when the refrigerant flows through the projecting member 60. Noise can be reduced by passing refrigerant through a block joint after pressure variation thereof is damped thereby suppressing vibration of the block joint.
