Patent JP-S62222647-A (JP)
Title: Auto-prober
Inventor: SATO KAZUYUKI
IPC: G01N21/84
Filed: 1986-03-25
Abstract: PURPOSE:To shorten a sweeping distance maximally, and to make the selection time per wafer the shortest by automatically computing the direction of a short side by the size of a pellet being given and conducting sweeping in the direction of the short side. CONSTITUTION:An operator inputs pellet size to an auto-prober prior to work, but the short side of a pellet is computed automatically from the value of the pellet size. When the direction of a Y axis is shortened as shown in the figure at that time, sweeping is conducted, using the Y axis as the direction of sweeping. Accordingly, when an auto-handler sweeps in the direction of the long side of the pellet in conventional devices, the number of folding is made larger than sweeping in the direction of the short side, and overall travel is increased, but the direction of the short side of the pellet is swept positively at that time, thus shortening the selection time per wafer maximally.

IPC: H01M4/133
Filed: 1991-03-07
Abstract: PURPOSE:To realize a charge and discharge cycle which is high in energy densi ty, free of pollution and good under high temperature circumstances by using specified mixed solvent as organic solvent for electrolyte. CONSTITUTION:In a nonaqueous electrolyte secondary battery with the positive electrode made of LixMO2 (where M represents at least one type of Co, Ni and Mn, and x is within 0.5-1) and the negative electrode made of carbon material, mixed solvent of propylene carbonate and dipropyle carbonate is used as organic solvent for electrolyte. For example, if LiCoO2 is used for the positive electrode, charging causes such a secondary battery to be formed that carbon lithium interlayer compound is served for the negative electrode, as shown in Expression I for reaction. The charge and discharge reaction is shown in Expression II. As dipropyl carbonate has the highest boiling point, 167 deg.C, in various chain cabonate, a good cycle life is achieved under high temperature circumstances.

Filed: 1989-03-20
Abstract: PURPOSE:To reduce the cost of the optical device without using a cylindrical lens by providing a parallel flat plate having a refractive index distribution in a sub-scanning direction between a light source and a deflector. CONSTITUTION:A collimator lens 2 and a slab lens 3 of a distributed index type are disposed between the laser light source 1 and a rotary polygon mirror 4. The slag lens 3 is the lens of the parallel flat plate having the refractive index distribution in the sub-scanning direction and is so formed that the refractive index at the center is high and is lower toward the periphery. The thickness at which the distribution of the refractive indices is given by an ion exchange, etc., can be utilized as it is with the parallel flat plate and the cylindrical refracting power is adjusted by the cutting length in this thickness direction. A laborious stage for polishing a curvature is, therefore, omitted without using the conventional cylindrical lens and the cost is reduced.

Abstract: PURPOSE:To carry out tap changing at the time of loading in high reliability by constantly monitoring the consumption of an arc contact by detecting the locus of the rotation of the fulcrum pin of the link mechanism of a tap changer. CONSTITUTION:The fixed fulcrum pin 3 of a link slides in a groove 9 at the tip of an arm 2 fixed on a driving shaft 1 and the pin 3 moves according to the consumption of a contact. A spring 10 gives a contact load to the contact. One end of each of the links 4-7 is supported by the pin 3 in a state of possible sliding and the other end bear contacts HA', WA', WB' and HB' on the movable side. Movable sides of the main contacts HA', HB and the resistance contacts WA, WB are fixed to the links 4-7, and fixed sides are to the inner periphery of an insulation cylinder 8. The central point of the fulcrum pin 3 is detected by means of sensor S1, S2. If the contacts WA, WB are previously consumed in a manner of nonuniform consumption, the rotaion of the arm 2 is smooth in the first half but difficult in the latter half. The change of the circuit locus Rc of the rotary fulcrum 3 of a link mechanism according to the consumption of the contact is detected by means of the sensors S1, S2 and if the tolerance is exceeded, the contact is replaced. This structure enables tap changing at the time of loading with high reliability.

Title: Power supply system
Inventor: NAKAHARA MAKOTO
IPC: H02J1/00
Filed: 1992-02-18
Abstract: PURPOSE:To provide a power backup system which reduces the capacity of power and reduces the number of power sources while maintaining reliability. CONSTITUTION:Power sources 1A-1C supply power to loads 2a-2c through reverse flow checking diodes 5a, 6a1, and 6a2, and 5b, 6b1, and 6b2, and 5c, 6c1, and 6c2. The capacities of the power sources 1A-1C are set to the values capable of supplying power to loads with residual power sources even if one power source goes wrong. When all power sources 1A-1C are normal, respective power sources supply power, having margin within the range of rated capacity. If one power source goes wrong, other two units supply power to the loads with rated capacities. Hereby, highly reliable power supply becomes possible with small number of power sources and the maximum maximum capacity.
