A control apparatus includes a body, a fixation plate and a control circuit arrangement. The body includes first and second fluid passages, which conduct fluid. The fixation plate is installed to the body on one side of the body and includes a third fluid passage, which has a first end connected to the first fluid passage and a second end connected to the second fluid passage. The third fluid passage conducts the fluid from the first fluid passage to the second fluid passage. The control circuit arrangement includes a board and a plurality of on-board devices. The board is installed to a surface of the fixation plate, which is located on one side of the fixation plate that is opposite from the body. The on-board devices are arranged on one side of the board, which is opposite from the fixation plate.

An automatic transmission control system equipped with a shift lever position sensor which includes a plurality of switches which output binary signals following a shifting motion of a gear shift lever. Patterns of combinations of the switch outputs are preselected so as to represent positions to which the gear shift lever is manually shiftable. The switches are broken down into two groups each of which produces a binary code carrying information about the position of the gear shift lever to monitor a failure in operation of the shift lever position sensor. The control system also works to perform a deemed D-position hydraulic transmission control to ensure the running of the vehicle even if the shift lever position sensor is failing.

A vehicular occupant restraint system includes a distance sensor, an electromagnetic wave radiation-type occupant sensor, a controller, and an airbag drive circuit. When the controller predicts a collision and determines it is unavoidable based on the output of the distance sensor, the controller sends an instruction signal to the occupant sensor to determine the seating condition of an occupant. Then, the airbag drive circuit performs an airbag deployment control in accordance with the determined seating condition. This system thus reduces power consumption and electromagnetic wave radiation of the occupant sensor.

A hydraulic pressure control system for an automatic transmission is capable of reducing the size and simplifying the structure of a lockup controlling hydraulic circuit. An oil pressure output from a solenoid valve acts on an oil pressure chamber. The internal pressure of another oil pressure chamber becomes high only in a forward low-speed range and becomes low in all of the other gear shift ranges. The internal pressure of another oil pressure chamber becomes high only in forward ranges and becomes low in neutral and reverse ranges. The valve member moves in accordance with oil pressures applied to the oil pressure chambers to change over oil paths connected to a clutch control oil chamber and a torque converter oil chamber, whereby a lockup clutch assumes one of engaged, slip, and released states. Since an oil pressure signal according to a gear shift range and a vehicular running range is fed to the changeover valve and on the basis of this signal the changeover valve determines whether the engagement of the lockup clutch is to be permitted or inhibited, the circuit of a lockup control unit can be reduced in size and simplified.

Hydraulic pressure applied to an LR/B is controlled by a first solenoid valve when a forward-movement range is selected, and is controlled by a second solenoid valve when a backward-movement range is selected. In addition, in the forward-movement range, the second solenoid valve controls hydraulic pressure applied to an OD/C which couples at a different gear position from the LR/B. When both solenoid valves fall into non-excitation states due to the breaking of an electric signal line, the failure of an AT ECU or the like, the output hydraulic pressures of the solenoid valves is held high and low, respectively. Therefore, even in this case, double coupling of the LR/B and the OD/C can be prevented in the forward-movement range as well as a predetermined gear position can be established in each of the forward-movement range and the backward-movement range.

A vehicular automatic transmission (AT) hydraulic controller has an integrated valve. The integrated valve has a cylindrical cam shaft including convex and concave parts on the outer periphery thereof, and the integrated valve is connected to a motor for automatic control and a connecting part which is interlocked with an external gearshift operated by a driver. Hydraulic control of the integrated valve can be performed in two different ways, i.e., automatic control and manual control, and even if automatic control malfunctions due to an error, manual control can maintain the control of the AT and avoid any inconvenience. The structure of this integrated valve provides a high degree of design freedom and can implement a wide variety of AT functions. Accordingly, a light, compact and reliable AT equipped with both an automatic control mechanism and a manual control mechanism can be provided.

A cable tie includes an elongated strap and a buckle connected to one end of the strap and having an aperture for receiving the other end of the strap. Preferably, the strap has adjacent the buckle a connecting portion which has a width less than that of the remaining portion of the strap. In an alternative form of the invention, the strap has a plurality of spaced-apart projections formed on and extending longitudinally on the opposite side surfaces thereof except a connecting portion adjacent the buckle. In a further modification of the invention, the strap has a series of ridges formed on and extending longitudinally on a bundle engaging surface. The ridges are adapted to prevent slipping movements between the strap and the bundle in both longitudinal and circumferential directions of the bundle of wires or the like.

A method for controlling a particle diameter and a particle diameter distribution of emulsion particles during manufacturing of an emulsion dispersion is provided. The method includes causing two or more types of liquids substantially immiscible with each other to continuously and sequentially pass through net bodies. The net bodies are disposed in a cylindrical flow passage at intervals of 5 to 200 mm, and the number of the net bodies is more than 50 and 200 or less. Each of the net bodies is equivalent to a gauze having a mesh number of 35 mesh to 4000 mesh in accordance with an ASTM standard and has a surface that intersects the direction of the flow passage. An emulsification apparatus used for the method includes a feed pump for feeding two or more types of liquids substantially immiscible with each other; and a cylindrical flow passage to which the two or more types of liquids fed by the feed pump are delivered. A predetermined number of net bodies are disposed in the cylindrical flow passage at predetermined intervals, and each net body has a surface intersecting the direction of the flow passage.
