A box-shaped electronic control unit for use in an automotive vehicle includes a pair of side stays for mounting the electronic control unit on a vehicle. The side stay integrally formed with a bottom cover is bent upward to form a bent portion. When electronic control units are carried by a conveyer, they are placed on a conveyer belt so that the bent portions face one another, thereby to avoid overlapping of the electronic control units on the conveyer belt. To form the side stay having a sufficient mechanical strength endurable against a high vibrating force of the vehicle, a pair of ribs extending from both sides of the bottom cover are formed on the side stays.

Electronic control unit for use in automotive vehicle

A casing for an electronic control device, by which a cover and a casing body are reliably sealed up while preventing the cover from warping or from being distorted, although the cover is made of a thin sheet material. The electronic control device casing comprises: a casing body having an opening in its upper face portion for casing a printed circuit board; a cover made of a sheet material for closing the opening of the casing body; a groove portion formed in the open edge portion of the casing body; a liquid sealing material fitted in the groove portion for sealing the open edge portion of the casing body and the flange portion of the cover; and a ridge portion having a generally U-shaped section and formed on the flange portion of the cover for being fitted in the groove portion of the casing body.

Casing for electronic control devices

A casing for an electronic control unit is composed of an upper case having a bottom opening and a bottom plate closing the bottom opening. The upper case is so formed that plural upper cases are easily stacked up and picked up one by one by an automated vacuum sucker. The sidewalls of the upper case facing each other are slanted, and a fringe portion is formed at a bottom end of each slanted sidewall. A U-shaped portion or a protrusion is formed on the fringe portion to prevent the upper case from sticking to another upper case when plural upper cases are vertically stacked up.

Casing for electronic control unit

A casing of an ECU is formed within an air cleaner of an intake module for an internal combustion engine. The casing faces an intake air passage, and formed in a pocket, so that the casing is easily formed and the water and dust proof performances thereof are improved. A printed-circuit board to which a metal plate is fixed is inserted into the casing along slits formed on an inner wall of the casing. The slits pinch the printed-circuit board and the metal plate at the rear end area thereof. Thus, anti-stress and anti-vibration performances of the printed-circuit board are improved. The metal plate including convexes and concaved contacting portions is easily formed by pressing an aluminum or steel plate. Thus, the metal plate is formed with low cost. Further, the metal plate appropriately includes holes, thereby promoting the heat radiation and reducing the weight thereof.

Installation structure of printed-circuit board for electronic control unit

A case which accommodates electronic control circuit is housed in a housing box. An air passage is formed between the case and a main body of the housing box to introduce cooling air for cooling an electronic control circuit in the case. A heat sink is attached to an inner surface of the case by a screw placed in a through hole formed in an area of the case to which the cooling air is not introduced. Accordingly, the electronic control circuit in the case is prevented from dust, water and the like. Further, the electronic control circuit is efficiently cooled down by the cooling air passes through the air passage via the heat sink and the case because an exothermic electronic element of the electronic control circuit is making a contact with the heat sink.

Cooling device for electronic parts of vehicle

A shock absorber which selectively produces different magnitudes of damping forces includes a cylinder and a piston slidably disposed in the cylinder and dividing an interior space of the cylinder into first and second fluid chambers filled with a fluid. A housing assembly coupled to the piston has a main fluid passage providing fluid communication between the first and second fluid chambers at all times and an auxiliary fluid passage providing selective fluid communication between the first and second fluid chambers. The auxiliary fluid passage can be opened to provide fluid communication between the first and second fluid chamber in response to an external control signal. The auxiliary fluid passage can be closed to cut off fluid communication between the first and second fluid chambers when the speed of relative movement of the cylinder and the piston is substantially zero, i.e., when the speed of expansion and contraction of the shock absorber is substantially zero.

Shock absorber with adjustable damping force

An air cleaner using an ionic wind having discharge electrodes, a counter electrode arranged downstream of the discharge electrodes, and first and second parallel plate electrodes arranged alternately downstream of the counter electrode. The second parallel plate electrodes are connected to a potential pick-up electrode arranged in the vicinity of the discharge electrodes. The first and second parallel plate electrodes which are arranged alternately serve as dust collecting electrodes.

An air spoiler apparatus with solar cells includes an air spoiler wing mounted on an outer surface of a vehicle body, solar cells mounted on an upper surface of the air spoiler wing, a running detector for detecting a running state of a vehicle, and an elevation angle adjustment unit of the air spoiler wing. The air spoiler elevation angle adjustment unit adjusts an elevation angle of the air spoiler wing within select angular ranges to increase power generation efficiency of the solar cells during parking, stopping, low-speed or high speed running represented by the running state detected by the running detector. During high speed operation the angular range is restricted to an optimum range for aerodynamic efficiency.
