The present invention protects a thin wire connection from oscillation of a resin protecting an electronic circuit module from vibration, impact, and corrosion. An electronic control unit including an electronic circuit module in which a bare chip is mounted on a circuit board and a case for housing the module, is provided, wherein the case is filled with a potting gel to protect the module. The bare chip, including its wire connection to the circuit board, is sealed in advance with a gelatinous resin having thixotropy prior to hardening. The gelatinous substance cures to form a hardened inner layer which has a penetration that is lower than that of the filled potting gel after hardening, and functions to eliminate or substantially reduce the affect of viscoelastic oscillation of the outer layer on the bare chip and the wire connection.

In an electronic control unit, a transmission control module for controlling an automatic transmission and a position sensor for detecting the range position of the automatic transmission are built in a common unit case. A first member and a second member to be fitted at the time of mounting the electronic control unit on an automatic transmission case are directed in the mounting direction when mounted on the automatic transmission case, and a third member is mounted on those two members. A predetermined clearance is formed at a predetermined portion on the mounting path between the automatic transmission case and the third member. When the electronic control unit is mounted on the automatic transmission case, therefore, the clearance on the mounting path inbetween absorbs the positional deviation between the first member and the second member thereby to facilitate the mounting work. Thus, the mounting workability of a position sensor built-in electronic control unit on an automatic transmission is improved.

A control apparatus includes a shift position detecting device for detecting a shift position that is changed by manual operation of the vehicle driver, an ECU for controlling an A/T based on a signal for a detected vehicle running state, and connectors that connect to an electrical unit outside the casing. Further, the shift position detecting device, the connectors, and the electronic control unit are electrically connected through a connecting board. Consequently, the shift position detecting device, the ECU, and the connectors can be freely laid out.

The impossibility of starting a starter motor by using a non-contact type position sensor for deciding an engine start is eliminated. An engine starting apparatus includes a non-contact type position sensor for detecting the range position of a drive mechanism having a prime mover as a power source; a control device for the drive mechanism; drive means for driving the prime mover; a power source device for supplying an electric power to the drive means and the control device; and conduction means for making the drive means and the power source device conductive in response to a signal from an ignition switch S and a signal outputted by the control device on the basis of the range position detected by the position sensor. As a result, the starter motor can be started without mounting the contact type start switch.

A first parameter correlated with a degree of a variation in the output from the air-fuel ratio sensor is calculated. A possible range of a second parameter representing a degree of a variation in air-fuel ratio among the cylinders is determined based on the first parameter. The first parameter is calculated with an air-fuel ratio of a predetermined cylinder forcibly changed. A difference between the unchanged first parameter and the forcibly changed first parameter is determined. A first characteristic representing a relation between the second parameter and the difference is determined based on the possible range of the second parameter and the difference. One of the determination value and the first parameter calculated before the forced change is corrected based on inclination of the determined first characteristic.

The game control device may include a storage unit, a first match-up executing unit, a character ability updating unit, and a second match-up executing unit. The storage unit stores an ability value of each player character. The first match-up executing unit executes a first match-up between two player characters in response to input of a communication terminal, and to determine a result of the first match-up based on the stored ability value of each player character. The character ability updating unit updates, based on the result of the first match-up, the ability values of the two player characters, and causes the storage unit to store the updated ability values. The second match-up executing unit executes a second match-up between player characters independently from the first match-up without input of the communication terminal, and determines a result of the second match-up based on the stored ability value of each player character.

A method for assembling an arc-extinguishing chamber of an electromagnetic contactor includes a step of fixing a pair of fixed contacts each including a support conductor and a C-shaped part, to a bottom plate part of the arc-extinguishing chamber having a tub-shape with one end being open, the C-shaped part defining inside of the arc-extinguishing chamber; a step of installing an insulation cover covering a part other than a contact point part of each C-shaped part of the pair of fixed contacts; and a step of disposing a movable contact to be capable of contacting to and separating from the contact point parts of the fixed contacts.

Embodiments of the invention provide an actuator head suspension assembly having an efficient voice coil. In one embodiment, a voice coil is formed in a circular or any other shape than the conventional sectorial shape to increase the efficiency of the voice coil and diminish oscillation and noise of an actuator head suspension assembly. The voice coil shape is selected such that the proportion of an out-of-plane force becomes smaller than that in the conventional sectorial voice coil and the proportion contributing as weight to the oscillation energy also becomes smaller.

A first parameter correlated with a degree of fluctuation of output from an air-fuel ratio sensor is calculated, and whether or not the calculated first parameter has a value between a predetermined primary determination upper-limit value α1H and a primary determination lower-limit value is determined. Such forced active control as reduces an air-fuel ratio shift in one of the cylinders which is subjected to a most significant air-fuel ratio shift is performed when the calculated first parameter is determined to have a value between the predetermined primary determination upper-limit value and the primary determination lower-limit value. A first parameter is calculated while the forced active control is in execution. The calculated first parameter is compared with a predetermined secondary determination value to determine whether or not variation abnormality is present.
