In a valve member, supply and discharge apertures of fluid are formed at a body having a fluid space E. A one electrode Da including a contact T is provided at an aperture edge of the supply aperture and/or a peripheral part of an aperture edge of the body. The body includes another electrode Db, and stores a valve member made of a conductor and opening and closing the supply aperture, and a coil spring made of a conductor and urges the valve member. A guide member made of a conductor is attached onto the valve member. The guide member is formed to secure a flow path of the fluid from the supply aperture to the discharge aperture while being slidable in the fluid space E, has a reception surface facing one end face of the fluid space E while receiving the fluid from the supply aperture.

Flow detector

A probe comprises: contact parts to be electrically connected to input/output terminals of an IC device built in a semiconductor wafer under test; interconnect parts at the front ends of which the contact parts are provided; a plurality of beam parts on the top surface of which the interconnect parts are provided along the longitudinal direction; and a base part supporting the plurality of beam parts all together in a cantilever fashion, the beam parts are supported by the base part at a rear end region of the beam parts, and grooves are provided between the adjoining beam parts in the rear end region.

Probe and probe card

A method for manufacturing a probe card includes a first contact formation step of forming a first contact on a first surface of a first sacrificial substrate, a second contact formation step of forming a second contact on a first surface of a second sacrificial substrate, a signal transmission line formation step of forming a signal transmission line in the base substrate, a first contact joining step of attaching the first surface of the first sacrificial substrate to the base substrate and joining the first contact to the signal transmission line, and a second contact joining step of attaching the first surface of the second sacrificial substrate to the base substrate and joining the second contact to the signal transmission line.

A compact, battery-powered video camera comprises a camera body provided with a built-in VTR deck, a viewfinder and a built-in microphone, a first battery mount formed integrally with the camera body, an accessory adapter provided at least with video/audio output terminals and capable of being detachably joined to the first battery mount, a second battery mount formed integrally with the accessory adapter, and a battery package capable of being detachably joined to the second battery mount. When the video camera is used only for recording pictures, the accessory adapter is removed from the camera body, and the battery package is joined directly to the first battery mount to reduce the size and weight of the video camera. In reproducing recorded pictures, the accessory adapter is joined to the first battery mount, the battery package is joined to the second battery mount, and the video camera is connected electrically through the accessory adapter to a television receiver.

In order to provide a compact carrying handle arrangement for a video camera which is not provided with carrying handle connections per se, the lower horizontally extending portion of an essentially C-shaped handle extends along the lower edge of the camera and is secured thereto by a screw which is threaded into the threaded bore provided for connecting the tripod. The vertical portion of the handle has a connection site which can operatively engage with a first battery mounting site provided on the rear of the camera. A second battery site is provided on the handle and is arranged to receive the battery. The second mounting site is electrically connected with the connection site so that power from the battery can be supplied to the camera via the first battery mounting site. The grip portion of the handle extends forward in a space relationship over the top of the camera. Hot shoes are formed at the leading end of the grip portion and operatively connected with the second battery mounting site so as to enable power to be supplied thereto from the battery.
