摘要:
A customer submits a service application by accessing the home page of a service provider through a personal computer 3, and transmits the data including the operation amount and the control amount of a temperature controller 4 to a server 2 of the service provider. The server 2 accumulates the received data, and in accordance with the contents of the received service application, processes the accumulated data and provides the services of calculating the control parameter for the temperature controller 4, producing a model of the object of control and making a diagnosis by checking for a temperature control fault.

A housing is constructed of a transmission case and an oil pan and has a space therein. A through hole passes through the transmission case. A pressure control unit is housed in the housing and controls hydraulic pressure supplied to a transmission mechanism by the operation of a solenoid valve. An internal cable is housed in the housing and is electrically connected to the solenoid valve of the pressure control unit. An external cable is electrically connected to an engine control unit outside the housing. A connector is arranged in such a way as to pass through the through hole and is electrically connected to the internal cable and the external cable. The connector has an external exposed portion, which is exposed outside the housing, formed in such a way as to be able to pass through the through hole.

A semiconductor device prevents the OFF current of a complementary field effect transistor from varying with changes in ambient temperature. The semiconductor device includes: a substrate voltage generating circuit that generates the substrate voltage of an n-channel MOS transistor forming a CMOS; a replica transistor that is a replica of the n-channel MOS transistor, and is diode-connected; and a voltage applier that applies a voltage of a predetermined voltage value between the anode and cathode of the replica transistor. In this semiconductor device, the substrate voltage of the replica transistor is the substrate voltage generated by the substrate voltage generating circuit. The substrate voltage generating circuit controls the substrate voltage to be generated so that the current value of the current flowing into the replica transistor becomes equal to a given target value.

The present high-frequency distribution circuit includes a switch circuit which passes a high-frequency signal from the other terminal of a high-frequency line to an output terminal if a receiver is connected to the output terminal and which grounds the other terminal of the high-frequency line via a terminator resistor if the receiver is not connected to the output terminal. As seen at an input terminal toward the output terminal, a constant value in resistance is provided regardless of whether the output terminal is used or not.

A fluid circuit module controls a fluid to be supplied to a movable element in an automatic transmission. The fluid circuit module is provided with a first body in which a first flow passage is formed, a second body in which a second flow passage is formed. A separation plate is set between the first body and the second body and has a deformation portion that is deformed and strained in accordance with the difference between pressures in the first flow passage and the second flow passage. A strain sensor is attached to the deformation portion for detecting a strain of the deformation portion. A control means controls a supply fluid to be supplied to the movable element on the basis of a detection result of the strain sensor.
