Title: Mechanism for feeding ic magazine
Inventor: KASAI SHINICHI
IPC: B65G47/08
Filed: 1985-07-30
Abstract: PURPOSE:To improve workability and efficiency by opposing the longitudinal direction of a magazine to the throw-in part of a handler while including said magazine so that a carry-in part side is low, in a feeding mechanism of an IC in a magazine into a large handler. CONSTITUTION:A magazine 5 is held by a holding arm 2, and lifted up along a supporting pillar 3. And, when it is lifted up to the position of the IC carry-in part 4 of an IC handler, the end part of the send-in part side of the holding arm 2 is locked to one end of a preheat chute 4a. Thereby, as the holding arm 2 is further lifted up, only the opposite side to the send-in part 4 side of the holding arm 2 is lifted up, inclining the holding arm 2. And, as the inclined angle agrees with the angle of the preheat chute 4a, the magazine 5 is combined with the chute 4a, and the IC in the magazine 5 falls naturally into the chute 4a. By this structure, workability and efficiency can be improved.

IPC: H04L12/28
Filed: 1990-06-28
Abstract: PURPOSE:To reduce the load of a CPU by sending a list and a file name to a local area network LAN controller by the CPU and retrieving the address of a disk device to fetch the corresponding file data and to send a data packet to the LAN by the LAN controller itself. CONSTITUTION:A CPU 11 sends a file name-address list and a file name to a LAN controller 16. Then the controller 16 itself retrieves the address of a disk device containing a relevant file based on the received list ad file name and then fetches the corresponding file data out of a disk device 12 by reference to the retrieved address. Then the controller 16 generates a data packet and sends it to a LAN. Thus a data server function of high performance is obtained without giving the load to the CPU 11.

Inventor: YAMADERA HIDEYA
IPC: G01L9/16
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a high-sensitivity strain detecting element which can detect strains with a simple circuit. SOLUTION: A strain detecting element is constituted by successively forming a magnetic layer 2, a conductor layer 3, and another magnetic layer 4 on a substrate 1 in this order in such a way that the conductor layer 3 is surrounded by the magnetic layers 2 and 4. While a high frequency is impressed upon the conductor layer 3, the impedance of the element section of the element is measured. Since the impedance changes in accordance with the strain of the substrate 1, the strain can be measured. Particularly, when the magnetic layers 2 and 4 and conductor layer 3 are laminated upon another, the variation of the impedance against the strain becomes larger even at a low frequency.

Abstract: PURPOSE:To detect a logical air fuel ratio accurately and also detect an air fuel ratio other than the logical air fuel ratio by providing two sets of air fuel ratio sensors each consisting of a solid-state electrolytic oxygen pump and a solid- state electrolytic oxygen sensor. CONSTITUTION:Air fuel ratio sensors 2 and 2' are arranged in the exhaust pipe 1 of an engine. The sensor 2 is constituted by arranging a solid-state electrolytic oxygen pump 6 and a solid-state electrolytic oxygen sensor 10 at an extremely small interval (d) opposite to each other. The sensor 2', on the other hand, has the same structure as the sensor 2. when a pump current flows, the oxygen partial pressure in the gap of one sensor 2 lowers below the oxygen partial pressure in exhaust gap outside of the gap, and the oxygen partial pressure of the other sensor 2' rises to the contrary. Consequently, both pump currents vary abruptly almost at the logical air fuel ratio. Therefore, the logical air fuel ratio is detected accurately and air fuel ratio other than the logical air fuel ratio are detected.
