摘要:
A semiconductor module has metallic radiator plates provided at central regions of principal surfaces of a sealing resin so as to expose from these principal surfaces. The metallic radiator plates and the principal surfaces of the sealing resin are bonded via grease gaps to heat receiving members. The grease gaps are widened in outer regions far from the metallic radiator plates compared with inner regions adjacent to the metallic radiator plates, to prevent external air from entering into the grease gaps even when the semiconductor module causes repetitive thermal expansions and contractions.

A harness fixing protector includes a base member which has fixing portions for fixing the base member to an attachment portion at both ends thereof and a cover member which is attached to the base member. The base member has a first harness inserting portion for inserting and fixing a first wire harness and a second harness inserting portion for holding a second wire harness so as to allow a movement of the second wire harness in a length direction thereof.
摘要:
A metal terminal has a terminal body (19) having a crimp part (5) crimped to a wire and a fastening part (25) connected to the terminal body (19) through breaking parts (21, 21). The fastening part (25) has a through-hole (23) for passage of a bolt (7). The metal terminal further includes a co-fastening part (27) formed in the terminal body (19). The tip side of the co-fastening part (27) is fastened to a vehicle body (13) by the bolt (7), together with the fastening part (25). When detaching terminal body (19) from the vehicle body (13), one side of the one terminal body (19) is pulled up in a direction opposite to the fastening direction of the bolt (7) under condition that the fastening part (25) and the co-fastening part (27) are together fastened by the bolt (7). Consequently, the co-fastening part (27) is released from its fastened condition and a breaking force is applied on the breaking parts (21, 21).
摘要:
Supplying a predetermined amount of electric energy to a fine metal wire 4 in a short time causes the fine metal wire 4 to melt and evaporate. Following this phenomenon, a blasting substance 10 expands in volume, so that the evaporative expansion force resulting from the melting evaporation of the fine metal wire 4 is transmitted to and blasts a to-be-blasted object 5.

To make it possible to raise a door body even if it is damaged by an impact of vehicle traffic or falling objects when it is in a lowered state, and to keep the door body in a raised state even if it is damaged by a water pressure of a tsunami or a high tide when it is in a raised state. A door body 2 of a floating flap gate 1 is disposed at an opening or at an access way. When water flows in, a forward end 2b of which swings upwards, in a direction in which the water flows in and within a plane in a height direction, around a base end 2a thereof which serves as a center of rotation, to block the opening or the access way. The door body 2 is formed from a hard polyurethane foam 4 in the form of a sheet.
摘要:
There is provided a message image display device enabling a user to grasp a content of each massage image when a plurality of message images are displayed. A display control unit (76) causes a display unit (82) to display a screen containing a plurality of message images. A judging unit (78) judges whether display of at least a part of a message image is limited by one or more other message images. A display-time determining unit (84) determines a display time of each of message images according to the judgment result of the judging unit (78). The display control unit (76) displays each of the message images over the display time of the message image determined by the display-time determining unit (84).

An apparatus for ultrasonically detecting an edge of a web, includes a ultrasonic-wave transmitter transmitting ultrasonic-wave pulse train, a ultrasonic-wave receiver receiving the ultrasonic-wave pulse train and converting the received ultrasonic-wave pulse train into electric signals, the web being fed between the ultrasonic-wave transmitter and receiver, a rectifying circuit for rectifying the electric signals, a low-pass filter circuit for smoothing output signals transmitted from the rectifying circuit, a first sample-holding circuit for sampling an output signal transmitted from the low-pass filter circuit, at first timing, a second sample-holding circuit for sampling an output signal transmitted from the low-pass filter circuit, at second timing later than the first timing, a third sample-holding circuit for sampling an output signal transmitted from the first sample-holding circuit, at the second timing, and a differentially amplifying circuit for calculating a difference between output signals transmitted from the second and third sample-holding circuits.
摘要:
The invention provides a plastic sorting method and apparatus, which, when plastic pieces comprising a plurality of types of resin plastics are agitated and frictionally charged, are able to impart the plastic pieces a necessary amount of charge or polarity for the thorough separation even if the difference in the amount of the different types of plastic pieces is large and to increase the recovery rate. If the amount of a specified type plastic pieces (1) to be recovered is small, the agitation and the electrostatic separation is carried out after adding the specified type plastic pieces (1) as auxiliary frictional charging material (21) into the frictional charging device (3), and the auxiliary frictional charging material (21) remains in the frictional charging device (3) and is used repeatedly.
摘要:
A fusible and vaporizable substance (for example, a thin metal wire is used) 2 is fused and vaporized by supplying thereto a predetermined amount of electrical energy from a capacitor 14 of an electrical energy supply circuit 10 for a short period of time, and nitromethane 3 is detonated by a phenomenon in the process in which the fusible and vaporizable substance 2 fuses and vaporizes, so that an object to be blasted 4 is reliably blasted by this detonation force.
