Title: Fast breeder reactor
Inventor: TAKAKURA KENICHI
IPC: G21C1/02
Filed: 1990-10-29
Abstract: PURPOSE:To simplify the upper structure of a reactor, and ensure the easy design, manufacture and installation of the reactor by closing the upper opening of a reactor vessel with a cover having thermal insulation and radiation shielding function, and providing a core upper struc ture capable of retreating from a position immediately above a core. CONSTITUTION:When a reactor is operating, an adjustment link 25 is lifted and two parallel links 24 are kept near a suspension section 6a in a reactor vessel 2 for retreat from a position immediately above a core 1. In this case, a core upper structure 5a in the reactor vessel 2 is turned by a core upper structure drive device 22 in the vessel 2 and positioned just above the core 1, so that a control rod drive mechanism 7 draws or inserts a control rod in the core 1 without any hindrance via a control rod guide tube 7a. Output control is thereby made smoothly. At the time of fuel exchange, the upper mechanism 5a is first turned by the device 22 and made to retreat from the position just above the core 1. In this case, the retreat of the upper structure 5a is restricted by the reactor vessel 2 and, therefore, the aforesaid structure 5a is made to retreat in two directions alternately for enabling fuel rods to be exchanged alternately, starting with a rod at a position opposite to the retreat direction. According to the aforesaid construction, various problems are all eliminated, as no rotary plug is fitted, and cost reduction and higher reliability can be ensured.

Abstract: PURPOSE:To prevent adherence of dusts to a wafer, to stabilize measurements of electric characteristics and to improve yield by providing opposed platelike electrodes disposed near a stage, and a power source for applying a DC voltage to the electrodes. CONSTITUTION:A carrier 8 contained in a wafer 2 is charged in a carrier container 7, wafers 2 are transferred one by one to a stage 6, and the stage 6 is so regulated that one side of a pellet of the wafer 2 coincides with one moving direction of the stage 6. Then, each one pellet is moved, a probe 1 electrically connected to a measuring unit body is brought into contact with an electrode pad on the pellet, and the electric characteristics of the pellet are measured. In this case, a voltage is applied to an anode connected to the positive terminal of a power source 5 and a cathode 4. Accordingly, electrically positively charged dusts are attracted to the cathode 4, and electrically negatively charged dusts are attracted to the anode 3, thereby removing the collected dusts of the periphery of the stage 6. Thus, adherence of the dusts to the wafer 2 is prevented, measurements of the electric characteristics are stabilized, and yield is improved.

The stretchfilm 32 is held by respective pulleys 36c, 38c at both side edges and bent downward. The middle part of the stretch film is supported by a support member 60 to prevent it from lowering so as not to contact the lunch boxes 21 and the half-split chopsticks 51 and so as to promote smooth supply of the chopsticks.

Title: Method for controlling straightening push amount of over-straightening pipe
Inventor: MIYOSHI HISAMITSU
IPC: B21D3/10
Filed: 1986-12-06
Abstract: PURPOSE:To eliminate the problem of a defective pipe due to re-straightening by performing a re-straightening by multiplying the relational expression by the coefft. of <=1 from the opposite side of a pipe at the time when a pipe is attained to over-straightening as the result of a push operation based on the relational expression of the bend amt. and push amt. of the pipe. CONSTITUTION:In the case of performing a straightening by using the expression I (S=push amt. before over-straightening, D=bend amt.) the residual strain to restore is caused on a pipe and at the time when becoming in the state (b) of overstraightening a restraightening is performed by turning the pipe 180 deg., but the residual strain to restore acts and when a straightening is made with the push amt. S calculated by the expression I, an overstraightening comes again. In the case of straightening the pipe after its overstraightening in order to prevent it the push amt. S is decided by the expression II providing an overstraightening prevention coefft. beta. However it is made variable in the range of 0.7<=B<=0.95. Coefft. a, b, gamma are difficult to foresee correctly in advance and it is necessary to device through actual results based on the past experiences.

Title: Winder for magnetic tape
Inventor: KODAMA KIYOYUKI
IPC: G11B15/18
Filed: 1994-11-25
Abstract: PURPOSE: To increase the winding speed for a magnetic tape, to suppress the shaking of a winding shaft and to improve the wind-up accuracy of the magnetic tape by suppressing the bending of the tape caused at the time of high-speed revolution by exerting tensile force in the axial direction on the winding shaft. CONSTITUTION: In a magnetic tape winder D, when compressed air is fed into an air chamber 45A by starting a compressor 48, an air chamber 45B becomes the state of negative pressure by evacuation of the chamber 45B, the fixed end side of a winding shaft 6 is fixed in the axial direction by means of a fixed bearing part 3 and the side of a free end is sucked toward a movable plate 14B in the axial direction. Consequently, the shaking caused at the time of driving/rotating the winding shaft 6 is suppressed and the wind-up accuracy is improved. Since the shaking of the winding shaft is not caused even at the time of high-speed rotation, the magnetic tape can be wound up at a high speed.

Title: Route setting device and navigation apparatus
Inventor: ISHIZAKI TAKASHI
IPC: G08G1/0969
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To increase road data which are used to calculate a return route without increasing the time required for calculating the return route and to enhance the route quality. SOLUTION: A return point is used as a cost-calculation starting point 1, and a cost calculation is executed so as to be stored. When a route is deviated, a return route 3 is set on the basis of a cost calculation result by connecting a link in which the total cost up to the return route 1 from a present position 2 is reduced. The Dichstrer method comprises a characteristic that, after the completion of a cost calculation, a route to all points in a calculation range from a calculation starting point can be calculated. As a result, the return point 1 is used as the calculation starting point, and the cost calculation is executed, and by using its calculation result, the route up to all the points in the calculation range from the calculation starting point 1 can be calculated.  Consequently, the setting processing operation of the return route can be performed in a very short time when a route is deviated actually.
