There is provided a structure for connecting substrates to each other, which is capable of thinning an electronic device on which a plurality of circuit boards is mounted, saving a space of the electronic device, and detaching a circuit board from the electronic device. The circuit board unit includes a first substrate including, on a surface thereof, a first group of electrode terminals arranged in a matrix, a second substrate including, on a surface thereof, a second group of electrode terminals arranged in a matrix in alignment with the first group of electrode terminals, and an anisotropic electrical conductor sandwiched between the first and second substrates. The first and second substrates and the anisotropic electrical conductor are pressurized by means of a pressurizer to electrically connect the electrode terminals to each other through the anisotropic electrical conductor.

When a normal braking is performed, a master cylinder (32) and wheel cylinders (44FR, 44FL, 44RR, 44RL) are set to a conducting state. When an emergency braking is performed, the master cylinder and the wheel cylinders are joined together so that a large brake force can be generated. If the wheel cylinders are connected to an accumulator soon after the emergency braking, an increase in the wheel cylinder pressure can be prevented. Even after the emergency braking, the wheel cylinders and the master cylinder are maintained in the conducting state while the master cylinder pressure is rapidly increasing.

To present a disk loading device reduced in the thickness of the entire device, capable of loading plural types of cartridge and bare disk commonly, easy to handle in horizontal or vertical position, and particularly excellent in dust-proof performance or manual insertion and discharge performance of tray in power off state, a holder 100 moved back and forth by transfer means provided inside includes a detecting switch 114 of a shutter opener 103 and a detecting switch 115 of a disk holder 104, and these two detecting switches are combined, while a dust-proof member such as dust-proof cover 42 is provided in a passage to the disk and optical head 7 in an external air stream in the device, and therefore, immediately after putting the media into the holder 100, the type and state of the media can be detected, and breakage of device due to insertion of plural types of cartridge in wrong direction or wrong side can be prevented, and also contamination of the disk or optical head 7 by suction of dust or smoke can be also prevented. Moreover, the worm gear provided in a drive gear train 112 of the holder 100 is designed to exclude the axial force in the opposite direction of the loading motor 111, and meshing with the wheel 112 can be freely cleared, and therefore the loaded media can be easily discharged and taken out in power off state.

A vehicle height adjust control apparatus and method adjusts an actual vehicle height to a target vehicle height using a microcomputer that controls an electric motor, leveling valves and an accumulator valve on the basis of the actual vehicle height detected by vehicle height sensors, so as to eliminate any deviation of the actual vehicle height from the target vehicle height. If a hydraulic fluid temperature detected by a fluid temperature sensor is very low or very high, the microcomputer suspends the vehicle height adjusting control and the supply of hydraulic fluid to an accumulator by stopping the operation of the electric motor and a hydraulic pump and/or switching the valves to a closed state. The suspending control thereby prevents very high and low viscosities of the hydraulic fluid, or very low and high fluidities thereof, which prevent an undesirable increase of the load on the hydraulic pump and an undesirable decrease of the ejecting performance thereof.

A braking force control apparatus adapted to generate a braking force, which is larger than that generated in a regular case, when a predetermined braking operation is carried out, this apparatus aiming at preventing the occurrence of an unnecessarily large sensible deceleration during a low-speed travel of a vehicle. ECU (10) is adapted to judge whether or not an emergency braking operation has been executed on the basis of a master cylinder pressure (Pmc) and its rate of change (dPmc). When a judgement that an emergency braking operation has been carried out is given, a wheel cylinder pressure (Pwc) is quickly increased by supplying an accumulator pressure to the wheel cylinder. When a vehicle speed exceeds a predetermined level during the execution of the emergency braking operation, the wheel cylinder pressure (Pwc) is speedily increased (116, 118) by a braking assist regular control operation. When the vehicle speed is not higher than a predetermined level during the execution of the emergency braking operation, the wheel cylinder pressure (Pwc) is slowly increased (116, 120) by a braking assist starting special control operation.

An optical pickup (10) includes a light emitting element (11), a holding member (14), a light receiving element (18), and a base (13). The holding member (14) is fixed to the base (13) by a combined bonding portion (17). The combined bonding portion (17) is sandwiched between the holding member (14) and the base (13) so as to fix the holding member (14) to the base (13). The combined bonding portion (17) includes a first bonding portion (15) composed of a first adhesive and a second bonding portion (16) composed of a second adhesive having a higher curing shrinkage rate than the first adhesive. The first bonding portion (15) and the second bonding portion (16) are each sandwiched between the holding member (14) and the base (13), and the second bonding portion (16) is provided to cover at least a part of an outer peripheral surface of the first bonding portion (15). A difference between the curing shrinkage rate of the first adhesive and that of the second adhesive is 3.0% or less.
