摘要:
An engine mount system includes multiple liquid-filled engine mounts switchable to provide different mount characteristics by selectively introducing negative pressure or atmospheric pressure. On one of pipelines connected to the respective engine mounts for introducing the negative or atmospheric pressure into the respective engine mounts, a check valve and an orifice portion are provided in parallel. The orifice portion restricts an amount of air flowing therethrough, so that the mount characteristic of the engine mount connected to the one pipeline equipped with the check valve and the orifice portion does not undergo an abrupt change when the pressure introduced in the engine mount is switched from the negative pressure to the atmospheric pressure.

A front subframe 42 is formed of an aluminum alloy into a frame that is formed substantially into a shape of parallel crosses or into a rectangular shape and is made up of left and right front joint portions 64, 64 and left and right rear joint portions 71, 71 which are disposed at corners of the frame that is formed substantially into the shape of parallel crosses or the rectangular shape, and left and right longitudinal members 61, 61, and front and rear cross members 62, 67 which connect the joint portions 64, 64, 71, 71 together. The left and right front joint portions 64, 64 and the left and right rear joint portions 71, 71 are formed of an aluminum alloy die-cast product, whereas the left and right longitudinal members 61, 61 are formed of an aluminum alloy wrought product. In addition, connecting locations 76 . . . of a camber angle adjusting mechanism 157 are formed of an aluminum alloy die-cast product. Additionally, a rear cross member compound 63 is formed of an aluminum alloy die-cast product.

A hydraulic tubing support that reduces noise transmitted to an operator due to pulsation of hydraulic oil in a junction tube. The hydraulic tubing support structure includes a pair of left and right remote control valves for generating pilot pressures for the plurality of hydraulic actuators in response to an input operation performed on each operating lever, pump-side tubes and tank-side tubes respectively extending from the respective remote control valves, a junction tube for allowing communication of the tubes guided to below a floor plate through a through hole and communication of the tubes guided to below the floor plate through a through hole, and a middle reinforcement beam extending in a right-and-left direction and fixed to the lower surface of the floor plate. The junction tube is fixed to the middle reinforcement beam in a non-contact state with the floor plate.

A pushbutton switch mechanism has board 28 incorporating an electronic circuit thereon, metal sheet contact 26 disposed on board 28, a light-transmissive pushbutton disposed in an opening defined in a casing of the electronic device for being pressed from outside, the light-transmissive pushbutton having outer key top 22 and presser 25 formed with rubber sheet 24 for contacting metal sheet contact 26, and light-emitting elements 27 disposed on board 28 around presser 25 for applying light to a side surface of the presser 25. Presser 25 has a conical shape having an upper surface as a bottom surface substantially aligned with a lower surface of key top 22 and a vertex for contacting metal sheet contact 26. Light emitted from light-emitting elements 27 is applied to the entire side surface of presser 25.
摘要:
A semiconductive ceramic composition capable of exhibiting excellent electrical and physical characteristics sufficient to be used for a boundary-layer type semiconductive ceramic capacitor and such a capacitor capable of being increased in dielectric constant and insulation resistance and exhibiting excellent solderability and tensile strength of electrodes. The composition includes a SrTiO.sub.3 base material and an additive for semiconductivity consisting of Y.sub.2 O.sub.3 and Nb.sub.2 O.sub.5. The Y.sub.2 O.sub.3 and Nb.sub.2 O.sub.5 each are present in an amount of 0.1 to 0.4 mol % based on the composition. The capacitor includes a semiconductive ceramic body formed of the composition, a first conductive layer formed on each of both surfaces of the body and a second conductive layer formed on the first conductive layer. A process for manufacturing the capacitor is also provided.
