A slip angle estimation device for a vehicle comprises an imaging device for capturing an image of at least one of the front and the rear of the vehicle and a control unit. The imaging device is a CCD camera including a lens and an imaging sensor. The control unit is configured to determine a plurality of tracking points for a plurality of captured objects, determine an optical flow for the plurality of tracking points based on two images captured at predetermined elapsed time intervals, determine a vanishing point based on intersections of the plurality of optical flows, and calculate a slip angle of the vehicle based on a ratio of a horizontal distance between an image center and the vanishing point to a distance between a lens center of the CCD camera and an imaging sensor.

Provided are a heat exchanger that does not impede downsizing and removes water in the heat absorbing pipe adequately with a simple configuration even when the reduction in diameter of the heat absorbing pipe is made. A heat exchangerin which heat absorbing pipesare disposed in a multi-tier arrangement within a casingwhich is the passage of combustion exhaust gas, both pipe endsof each of the heat absorbing pipesare connected respectively to two headersprovided on a side plateof the casingand water introduced from an external pipeto each of the heat absorbing pipesthrough the headeris heat-exchanged and heated by combustion exhaust gas. The pipe endsof the heat absorbing pipesare arranged at a predetermined vertical interval. A drainage platefor forming a drainage passage through which the water that has reached the pipe end openingsA of respective heat absorbing pipesis removed during drainage operation for the heat absorbing pipesis disposed in the headerdisposed on a lower side of the heat absorbing pipesso as to face a number of the pipe end openingsA vertically arranged in a state of continuous.

An in-vehicle operation apparatus has an operation switch, a candidate selection operation unit, and a command assignment operation unit, all of which are operable by a user. The operation switch may control multiple in-vehicle devices based on a desired command assigned thereto. In particular, the candidate selection operation unit selects a plurality of candidate commands from among a plurality of commands respectively for in-vehicle devices. The command assignment operation unit selects and assigns the desired command from among the plurality of candidate commands to the operation switch. Accordingly, the operation switch controls the in-vehicle device associated with the desired command. Thus, the apparatus reduces the amount of operation switches required and allows the user to easily select and assign a command to the operation switch for controlling a desired in-vehicle device.

In-vehicle operation apparatus

An input device with touch input function has an input member which is operable to input at least one of shifting operation and pushing operation. The input member has a touch input device which is responsive to touch of a user. The input device has an operation sensor which detects the operation on the input member. The input member and the operation sensor provides an input unit which is supported by a support member in a manner that the input unit is movable among a lock position and an unlock position with respect to a base member on which the input unit is supported. The input device has a lock mechanism which locks the input member in inoperable condition at the lock position and which releases the input member in operable condition at the unlock position.

Input device with touch input function

A two-dimensional operation section includes a stick-shaped rocking shaft having an end having an operation knob. The operation knob is operated within a predetermined two-dimensional operation surface determined as an operation range such that a rocking axis of the rocking shaft tilts from a predetermined neutral angular position to a direction corresponding to an instructed position. A one-dimensional operation section has an operation surface exposed in a main surface of the operation knob, the main surface being an end surface of the rocking shaft. The one-dimensional operation section can be operated in a predetermined one-dimensional operation direction determined within the two-dimensional operation surface relative to the operation surface.

In-vehicle manipulation apparatus and in-vehicle input apparatus

A single can-type composite heat source machine including a single can body including a first combustion section having a first burner and a hot water supplying first main heat exchanger located above the first burner, and a second combustion section having a second burner and a second main heat exchanger located above the second burner and used for a purpose other than hot water supply. The first combustion section and the second combustion section are partitioned from each other by a partition wall and juxtaposed in a lateral direction. The machine includes a first auxiliary heat exchanger and a second auxiliary heat exchanger both of a latent heat recovery type connected to upstream sides of the first main heat exchanger and the second main heat exchanger, respectively. An exhaust system can be miniaturized and simplified in spite of provision of the auxiliary heat exchangers.

An inner sealing portion seals a tubular port, which is provided to a receiver that receives water, at a first location of the tubular port. An outer sealing portion seals the tubular port at a second location of the tubular port spaced from the first location on an outer side of the inner sealing portion. A sealed space is formed between the inner sealing portion and the outer sealing portion. A tracer gas for performing a leak test of the outer sealing portion is enclosed in the sealed space. An amount of outwardly leaked tracer gas, which leaks from the sealed space through the outer sealing portion, is measured with a leak test device.

Sealed device and leak test method and manufacturing method thereof

An airtightness failure inspection method according to the present invention comprises an initial step of generating an independent constant flow of gas in the interior of a cover formed in such a manner as to surround an inspecting area of an inspection object and a detector , a pre-inspection step of sealing a tracer gas in the interior of the inspection object under pressure and placing the cover over the inspecting area, a measuring step of introducing a gas containing the tracer gas that has leaked from the inspecting area and which is drawn out of the cover into the detector for measuring the amount of the leak and a cleaning step of cleaning up flow paths constituting the flow path systems and instruments including the detector after the measurement is completed.

Method and apparatus for inspecting for airtightness failure

A fault inspection system for the rotary machine is disclosed in which the rotational speed or a physical quantity related thereto of the rotary machine drive with changing rotational speeds is detected as a first detection signal, and the sound pressure or mechanical vibration from the rotary machine as a second signal. A reference line representing the relationship between the values of the first and second detection signals is determined on the basis of the same values. A fault of the rotary machine is detected on the basis of a third detection signal associated with an area corresponding to the region where the first or second detection signal exceeds the reference line.
