An inductive heating device is structured such that a coil base and ferrites placed under a heating coil in the vertical direction are flushed with each other at their lower surfaces and are directly placed on a heat dissipation plate. A heat conductive member is charged between the ferrites and an electrical insulating member sandwiched between the heating coil and the ferrites, at least at a portion thereof, so that thickness variations in the ferrites are absorbed thereby, which realizes a state where they are thermally coupled to each other from the heating coil to the heat dissipation plate.

To reduce the air exhausted to outside a main body after cooling a heat generating component from being taken in again from an intake port. The flow of cooling wind cooled the heat generating component is discharged from an exhaust port at other than a first peripheral wall with the flow bent inside the main body. When rectified inside the main body and discharged from the exhaust port, the cooling wind grows to a flow speed of a certain extent to become an exhaust air that a flowing direction is clearly defined, so that it is less likely to be taken in again from the intake port, it is less likely to be subjected to the influence of obstacles of the exhaust port, use can be made in a kitchen cabinet of the intake and exhaust air at the back side, and it is satisfactory and is less likely to be damaged without involving sense of unpleasantness by the exhaust air to the user.

A heating cooker of the present invention includes a plurality of light emitting indicator units. The light emitting indicator units each have a temperature sensing unit that senses an ambient temperature of a light emission source. Therefore, deterioration of the light emission source of each of the light emitting indicator units can be suppressed to realize a further reduction in thickness, and to improve visibility of the indicator sheet.

Heating cooker

A heating cooker of the present invention is structured such that, an indicator sheet of a light emitting indicator unit has a light transmitting portion that transmits light of a light emission source and a light blocking portion that is provided away from a heating unit than the light transmitting portion is and that blocks the light of the light emission source, and that the light emission source is disposed below the light blocking portion. Thus, uneven shining of the indicator sheet can be suppressed, and the effect of heat from a heating target cooking vessel to the light emission source can be suppressed, whereby a further reduction in thickness of the heating cooker can be realized.

An objective of the invention is to provide a multilayered flow passage member that enhances fluid measurement accuracy of an ultrasonic fluid measurement apparatus and an ultrasonic fluid measurement apparatus using the multilayered flow passage member. When fusible projectionsare fused by a heating headwhile partition platesare inserted into side platesand, a fused state provided by the heating headchanges according to either side of each of the partition plates, because fuse surfaces at leading ends of the respective fusible projectionsare sloped in the vertical direction. An outermost end of each of fusible projectionsthat first contacts the heating headis first fused. During a course of the fusible projectionsbeing fused toward their roots, the partition platesare pressed against ends of respective insert holesthat are on the opposite side of the outermost ends that are first fused. As a result, the partition platesbecome one-sided with respect to the respective insert holesand fixed by means of positional accuracy of the insert holes. Even when clearance exists between the partition platesand the insert holes, the partition plates can be fused with superior accuracy.

An acoustic matching member is fitted to a main body in a pair of ultrasonic transmitter/receivers. The acoustic matching member includes a matching member equipped with a porous body adhered tightly to an acoustic-wave emission surface of the main body. A dense layer is stacked on a surface of the porous body and includes a thermosetting resin and first flowability-diminishing particles. A sidewall member is adhered tightly to the acoustic-wave emission surface and an end face of the porous body.

The invention relates to a planar heat generating element for use on steering wheels of automotive vehicles and motorboats, and a problem of the invention is to adjust a temperature portion of a planar heat generating element which is attached to a steering wheel, so as to enhance the sensation of using the steering wheel by the user when he or she grips thereon. In the invention, since linear heaters () of a planar heat generating element () are provided so as to be turned repeatedly along a circumferential direction and such that the density of turns of the liner heaters () at an outermost circumferential portion of a ring portion () becomes sparse, the temperature of the outermost circumferential portion of the ring portion () with which the palms of the user are brought into contact when he or she grips the ring portion () can be made to be adjusted, and the heat generation of the planar heat generating element () can be adjusted so as to match the user's way of gripping, thereby the sensation of using the steering wheel felt by the user when he or she grips thereon being able to be enhanced.

The liquid fuel burning apparatus includes a fuel tank, a burning unit for burning the fuel, an electromagnetic pump for sucking the fuel from the tank, a feeding pipe for feeding the sucked fuel to the burning unit, and a control unit for controlling the electromagnetic pump. The electromagnetic pump has a plunger which is reciprocated by a plunger solenoid to suck the fuel in the fuel tank and discharge the sucked fuel therefrom in the associative motion of a suction and a discharge valves incorporated therein. The control unit opens the valves for a predetermined time when the fuel supply is stopped. Thus, fuel remained at an end of the feeding pipe is collected from so that the unburnt gas or strange smell which would be generated when the unnecessary liquid fuel is supplied to the burning means can be restricted.
