Abstract: A gear change control device actuates an actuator in response to an input of a gear change command and sets the clutch in an intermediate state between the engaged and disengaged states before a plurality of gears in the transmission are selectively engaged by dog clutches. In the intermediate state, a driving-side friction member and a driven-side friction member of the clutch are pressed against each other at a pressure lower than in the engaged state. The gear change control device actuates the clutch actuator to restore the friction clutch set in the intermediate state to the engaged state after the plurality of gears are selectively engaged.

The internal combustion engine includes at least two cylinders and an exhaust path. The exhaust path includes a convergent-divergent nozzle and an exhaust merging section provided upstream with respect to an upstream end of the divergent section arranged to connect only exhaust ports of combustion chambers for which the opening periods do not overlap.

In accompaniment with the passage of the exhaust gas having the pressure increased by the shock wave through the convergent-divergent nozzle, a new shock wave propagating in a downstream direction in the exhaust path is generated and also an expansion wave propagating in an upstream direction in the exhaust path is generated.

Wet-type multi-plate clutches provided in the transmission include a plurality of clutch plates fitted to a clutch rotating body for axial movement with the clutch rotating body. The clutch rotating body includes an oil reservoir in its inner bottom portion and arranged to hold lubricating oil and a peripheral wall arranged to cover the oil reservoir from the radial outside and fit to each of the clutch plates to permit axial movement of the clutch plates. Communicating holes are arranged on the peripheral wall such that they communicate the oil reservoir side to the outside of the clutch rotating body in the radial direction.
Abstract: An elastic wave device includes a piezoelectric thin film formed from a piezoelectric single crystal substrate by peeling, an inorganic layer formed on a rear surface of the piezoelectric thin film, an elastic layer disposed on a surface of the inorganic layer opposite to the piezoelectric thin film, and a support member adhered to a surface of the elastic layer opposite to the inorganic layer. The elastic layer reduces stress generated when the piezoelectric thin film provided with the inorganic layer and the support member are adhered to each other and has a predetermined elastic modulus. The inorganic layer is formed of a material having a higher elastic modulus than that of the elastic layer and prevents damping generated when the elastic layer is provided.
Abstract: Four mounting units are linearly disposed in a machine body of an image forming apparatus. First and second platen covers that differ from each other in weight also differ from each other in interval between support units. The first platen cover can be mounted on the machine body using the mounting units, and the second platen cover can be mounted on the machine body using the mounting units.
Abstract: For monitoring a data transmitter such as a streaming server, which supplies transmitted data in response to a request of a receiver, an examiner examines a data traffic at the input of a receiver or at the output of the receiver, the examiner being configured to ascertain whether the data traffic falls below a minimum threshold. If the minimum threshold is fallen below, a connection activator initiates a new connection between the receiver and the data transmitter. This serves to enable consistent data-transmitter monitoring, even for non-reliable point-to-point connections via the internet.

Abstract: A display system of the present invention includes a liquid crystal platform section (200) which outputs display data for displaying, on a liquid crystal display section (100), an image in accordance with information obtained from an automobile. The liquid crystal platform section (200) includes a DIC (201) which generates display data and calculates a display position of the image to be displayed on the liquid crystal display section (100) from the obtained information and which causes the generated display data to be displayed in the calculated image display position. The DIC (201) updates display so that the image moves at frame intervals from a start position of image display to the image display position calculated from the automobile information currently obtained, when an interval at which the information is obtained is longer than each of the frame intervals for displaying the image.

Abstract: A pressure sensor detects the change in pressure within a cylinder in a clutch master cylinder in a case where a clutch shifts from a connected state to a disconnected state. The pressure within the cylinder is detected at a time point where a rate of the pressure increase is changed. The position of a rod in this case or the rotation angle of a motor in an actuator is detected as a touch point preparation position. The touch point preparation position is a stage preceding power generated by an engine being transmitted to the clutch. The actuator moves the rod at high speed until the position of the rod reaches the position corresponding to the touch point preparation position.
