摘要:
A stepper motor control device includes a sensor that detects physical quantities and a control device that operates a stepper motor based on data corresponding to the physical quantities sent from the sensor in which the said control device implements a target rotational angle computation process that calculates a target rotational angle of a drive shaft of the stepper motor based on data corresponding to the physical quantities sent from the sensor, a target rotational angle change computation process that calculates a target rotational angle change which is a difference between a present rotational angle of the drive shaft of the stepper motor and the target rotational angle and a divisional target rotational angle computation process that equally divides the target rotational angle change by a first divisional target rotational angle within a range not exceeding a rotational limit for loss of synchronism of the stepper motor whereby the said control device is a drive control device of the stepper motor that drives the stepper motor by supplying to the stepper motor a second divisional target rotational angle which is a value calculated by the divisional target rotational angle computation process as a rotational angle per one control period.

An airbag deployment controller and a passenger protection device including the same are provided to prevent erroneous operation of an airbag due to noises and quickly deploy the airbag. The passenger protection device determines whether or not to drive an airbag unit, upon determining a detected value of a front acceleration sensor as being over a first collision threshold. Then, when determining to drive the airbag unit, the passenger protection device determines whether or not a detected value of a central acceleration sensor exceeds a second collision threshold. With the detected value being over the second threshold, it generates a driving signal and outputs it to the airbag unit in a final deployment control process. Thereby, the airbag unit operates an inflator to drive an airbag.

A muffler includes a shell main that is formed in a cylinder with two openings opposite to each other being apart from each other in an axial direction of the shell main body by rolling a flat plate to have an overlapped portion overlapping an inner end portion and a shell portion, and a pair of end plates that are partially inserted in the openings of the shell main body and fixed to the shell main body. The inner end portion is formed with two cut-off portions at opening-side edges of the inner end portion, respectively, to avoid interference between the inner end portion and the end plates when the end plates are inserted into the openings of the shell main body.

A variable capacity compressor includes: cylinder bores; a drive shaft; a rotor fixed with the drive shaft; a link for linking the rotor and a journal; a tilting plate capable of changing its tilted angle; and pistons capable of reciprocating within the cylinder bores along with a rotation of the tilting plate. Each reciprocating stroke of the pistons is adjusted according to the tilted angle of the tilting plate. The link is linked with the rotor via a first pivot and linked with the journal via a second pivot. An arrangement of the first and second pivot is set so that each head clearance of the pistons decreases as a discharge capacity decreases toward its minimum value within a small discharge capacity range. According to the compressor, it can be prevented that the discharge flaw amount is cut off abruptly and the tilted angle can be sustained stably.

An air conditioner (1) includes an air-blowing unit (4) and an air-conditioning unit (5).The air-blowing unit (4) includes a fan case (9, 10) defining a pair of independent scroll chambers (6, 7), a pair of fans (9, 10) respectively provided in the pair of scroll chambers (6, 7). The air-conditioning unit (5) includes an air-conditioning case (13) defining an air passage (P) which air from the air-blowing unit (4) flows and air-conditioning components (14, 15, 17) provided in the air passage (P) and configured to condition air flowing from the air blowing unit (4) therethrough. A partition (25) partitioning a portion (P1) of the air passage (P) from an inlet (P0) to the most upwind air-conditioning component (14) into a pair of independent passages (P1a, P1b) is provided. The pair of independent passages (P1a, P1b) respectively communicate with discharge ports (6b, 7b) of the pair of scroll chambers.

A radiator core support is made by an insert injection molding method. Four core members shaped in a triangular prism are built into a quadric-prism core and inserted into a rectangular tube, an upper radiator core support member. Then, an outwardly pressing member is inserted into a longitudinal slanted hole of the core to move and contact its members to the inner surfaces of the tube. The tube is located in a mold, into which molten molding material is injected. The tube is overmolded at the tops of a hood lock stay, and right and left side support members, being integrally formed out of resin. After cooling, the method includes drawing the pressing member from the core; then the core from the mold; and the molded part is removed from the mold.

A vehicle-mounted display apparatus (1) includes an indicator dial panel (2) and a scale gauge unit (20), which protrudes from the obverse surface (2a) of the indicator dial panel (2), and which is translucent. A pair of protrusion parts including a first protrusion part (23a) and a second protrusion part (23b) are installed upon an exterior surface (21) of the scale gauge unit (20). The pair of protrusion parts (23a and 23b) comprise incline surfaces (24a, 24b, 25a, and 25b), respectively, and these incline surfaces are inclined with regard to the indicator dial panel (2), respectively.

In a warm-up system that pre-warms up of an engine (E) by transferring heat from a heat source to an engine cooling water circulation circuit (1) of a vehicle, a residential hot water circuit (2) that uses a household heat source is provided as the heat source, and a one-touch connector (3) is provided in the engine cooling water circulation circuit (1) and the residential hot water circuit (2). The one-touch connector (3) connects the two circuits (1, 2) prior to start-up of the engine (E) such that heat is transferred to the engine cooling water circulation circuit (1), and disconnects the two circuits (1, 2) following heat transfer in preparation for start-up of the engine (E).

A lighting device, for illuminating display designed parts on a display plate arranged parts at-least-partially around a center axis, includes a light source for emitting light and arranged at a rear side of the display plate, and a light guide body having at least one light guide portion including an inner portion and an outer portion. The inner portion has a rear side surface for receiving the light from the light source and a front side surface with a curvature for reflecting the light to change a forward-backward direction of the flight inputted from the light source toward an outwardly radial direction to guide the light so that the light can travel in the outer portion in approximately radial directions centered on the center axis and be suppressed from diffusion from a central line passing through though the center axis and the light source.
