Title: Electronic device
Inventor: FUKUMAKI TAKASHI
IPC: H01L23/50
Filed: 1990-02-06
Abstract: PURPOSE:To improve reliability against cracks in a soldered part by forming a reaction layer mainly composed of Cu6Sn5 phase, between a copper based lead frame and solder. CONSTITUTION:An electronic parts 1 is connected, via a lead frame 2, with a conductor film 4 metallized on a printed board 3. The lead frame 2 and the conductor film 4 are fixed by using solder, and an electronic device is formed. When the Cu based lead frame is soldered by using solder which contains 0.3-3.0wt.% Zn, Cu6Sn5 phase is mainly formed in the reaction phase of a soldered part, and at the same time, alloy phase of Cu-Zn, Cu-Zn-Sn is formed. Hence, when the soldered part is exposed to a high temperature atmosphere, the growth of fragile Cu3Sn phase is restrained, so that the generation of cracks in the soldered part can be prevented.

Title: Automatic truck
Inventor: ITO HIROSHI
IPC: G05D1/02
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent a guide sensor from touching a travel surface and traveling zigzag about a guide line by controlling the position of the guide sensor above the travel surface to a higher position when a fast travel state is entered. SOLUTION: A cylinder control circuit controls cylinders 11F and 11B so that a rod 11L extends downward when a travel speed signal outputted by a travel control circuit is a signal corresponding to a predetermined slow speed. When the travel speed signal is a signal corresponding to a fast speed, on the other hand, the cylinders 11F and 11B are so controlled that the rod 11L contracts. Therefore, when the automatic truck 1 travels at a slow speed, guide sensors 12F and 12B fitted to the tip part of the rod 11L are nearby the travel surface and when the truck travels fast, the guide sensors 12F and 12B increase in the distance from the travel surface. Consequently, the guide sensors 12F and 12B never touch the travel surface even at the time of the fast travel wherein the body 2 vibrates large vertically.

Abstract: PURPOSE:To make it possible to facilitate the removal of a jamming recording sheet from the gap between the edges of first and second sheet cutter blades by supporting the first cutter blade rotatably in the direction in which the gap between the edges of the first and second cutting blades may be enlarged. CONSTITUTION:When a recording sheet 12 jams between a stationary blade body 2 and a movable blade body 3b, a releasing shaft 11 is moved in a desired direction so as to release itself from the engagement with a right bearing plate 4a so that a stationary plate attaching member 1a may be swung about a support shaft 3d. Then a picking member 14 is gripped so as to rotate the stationary plate attaching member 1a in the direction of the arrow C in order to enlarge the gap between the stationary blade body 2 and the movable blade body 3b. With this arrangement, the jamming recording sheet 12 can be easily removed through the gap. After removal of the recording sheet 12, the stationary blade body 1a is returned to its original position, and the releasing shaft 11 is inserted in an engaging shaft hole 4a-2 in the right bearing plate 4a, and accordingly, the condition in which a recording sheet can be cut by the blades 1, 3 is reestablished.

Title: Pseudo single mode optical transmission line
Inventor: TAKUMA TAKEYOSHI
IPC: H04B10/25
Filed: 1990-02-07
Abstract: PURPOSE:To allow the increase of the transmission capacity of a system even with an existing optical fiber transmission line at a low cost by connecting optical fibers of single mode of working wavelength to both ends of an optical fiber multimodes of working wavelengths. CONSTITUTION:The optical fibers 2 of the single mode working wavelength are connected at several m or above to both ends of the optical fiber 1 in multimodes of working wavelengths by confining the misalignment of the centers between the cores of the multimode optical fiber 1 and the single mode optical fibers 2 within 5mum.
