Abstract:
A device and system for connecting a car-mounted apparatus comprising a fixing plate installed to part of a car body for supporting the car-mounted apparatus, a female part formed in either the car-mounted apparatus or the fixing plate, and a male part extending from either the car-mounted apparatus or the fixing plate that can be freely engaged with and disengaged from the female part. The invention also relates to a device for supplying power to a car-mounted apparatus by electrically connecting a connector on the car-body and a connector on the car-mounted apparatus, where either of these connectors is installed so that it can freely move and integrally vibrate with the other connector when in an engaged condition.

A semiconductor device and a method for manufacturing the semiconductor device mountable with high density, which includes a simplified process but is capable of reducing a defect rate. A plurality of semiconductor chips of different kinds (processor chip and memory chip) are formed on a semiconductor wafer, and a go/no-go test is conducted on all the chips. The semiconductor wafer is cut and divided into pieces that each consist of a good processor chip and a good memory chip, and they are mounted on a substrate to form a semiconductor module.
Abstract:
A transfer system includes transfer lines (L) each of which forms a closed loop and has transfer-in stations (S1 and S3) and transfer-out stations (S2 and S4) for assembling parts to a work, while circulating the work along the transfer line (L); and a work and part transfer passage (51) for transferring the work and the parts. Transfer-in stations (S1 and S3) and the transfer-out stations (S2 and S4) are disposed at each of the longitudinal ends of each of the transfer lines (L). Sub-transfer-passages (521 and 522) branching out rightward and leftward from the work and part transfer passage (51), are disposed along longitudinal sides of the transfer lines (L). With this layout, a plurality of the transfer lines (L) can be disposed in a required minimum space, while securing a smooth supply and discharge of the works and parts with respect to the plurality of the transfer lines L.

A semiconductor device which is mounted with a plurality of semiconductor chips. The fraction defective is low when the device is manufactured, and the efficiency of inspection is high. A method for manufacturing such a semiconductor device is also disclosed. A plurality of kinds of semiconductor chips 1 are COB-mounted on a substrate 2 and the surface of the substrate 2 mounted with the chips 1 is encapsulated with a resin 3. Then all the chips 1 mounted on the substrate 2 are inspected at once. Semiconductor devices 10 are produced by cutting the substrate 2 into pairs of adjacently arranged two different kinds of semiconductor chips 1 together which are judged to be nondefective chips.
Abstract:
A digital still camera includes a lens system having a variable focal length. An image pickup unit is disposed on an optical axis of the lens system, for forming an image frame. Yaw and pitch rate sensors detect a camera shake to output shake information. A shake correction mechanism, associated with an anti-vibration lens, compensates for the camera shake by shifting perpendicularly to the optical axis according to the shake information. A memory stores an LUT of correlation information between the focal length and a shift amount of the shake correction mechanism to compensate for an image shake of the image frame created due to a change in the focal length. In case of lack of detected camera shake with the yaw and pitch rate sensors, the shake correction mechanism is controlled with a shift amount associated with the focal length according to the LUT.
Abstract:
A testing method for testing a semiconductor device includes heating the semiconductor device until the temperature of the semiconductor device reaches a predetermined temperature; conducting other functional tests other than testing of the overheat protection function in a second step after the temperature of the semiconductor device has reached the predetermined temperature; allowing the semiconductor device to generate heat by itself such that the overheat protection function of the semiconductor device is activated, detecting a first diode forward voltage of a desired diode contained in the semiconductor device when the overheat protection function of the semiconductor device is activated and computing a first computational temperature of the semiconductor device based on the detected first diode forward voltage of the desired diode contained in the semiconductor device; and determining whether the computed first computational temperature of the semiconductor device resides in the overheat protection function activating temperature range.
Abstract:
A transfer line (L) is formed by a first conveyer (C1) and a second conveyer (C2) which are disposed in parallel to each other for transferring a pallet, a first traverser (T1) for transporting the pallet (P) from a terminal end of the first conveyer (C1) to a start end of the second conveyer (C2), and a second traverser (T2) for transporting the pallet (P) from a terminal end of the second conveyer (C2) to a start end of the first conveyer (C1). The first and second conveyers (C1 and C2) are operable to drive main drive rollers (22) provided at start ends of the conveyers by bringing the rollers into abutment against side surfaces of rearmost pallets (P) in the advancing direction, thereby urging and collectively driving a plurality of pallets (P) which are connected together forwardly of the rearmost pallets (P) in a state in contact with the rearmost pallets. This enables the length of the transfer line (L) to be changed as desired without modification of a drive device for the pallet (P).
