Abstract: PURPOSE:To obtain the titled device capable of continuously precisely producing a small sphere by providing both a hourglass worm-shaped molding roll and a trapezoidal worm wheel-shaped holding base for a stock which interlocks and rotates with such a slight gap that this is engaged therewith. CONSTITUTION:Both a hourglass worm-shaped molding roll 1 and a trapezoidal worm wheel-shaped holding base 2 for a stock which interlocks and rotates without contacting with each other with such a slight gap that this is engaged therewith are provided, and furthermore both the rotary shaft 17 of the molding roll 1 and the rotary shaft 23 of the holding base 2 are mutually provided in the rectangular directions. The stock 25 falls on a groove provided on the holding base 2 and is slid along the groove or rolled down and made to a sphere after complicated contact and rolling movement, and falls in a lower gutter 26 through a notch 28 of the end of a screw of the roll 1. By this method, the gap of the molding roll 1 and the holding base 2 can be made extremely small and also the gap can be kept in consistent value, and therefore the melted stock 25 is not introduced into the gap even if it is small, and the highly precise sphere can be continuously produced.

Title: Group control system for elevator
Inventor: YOORISU SHIYUREEDAA
IPC: B66B1/20
Filed: 1987-04-10
Abstract: A group control assigns elevator cars to floor calls optimized in such a manner, that minimal waiting times result and the elevating capacity is increased. A computing device provided for each elevator calculates at every floor a sum proportional to the time losses of the waiting passengers from the distance between the floor and the car position as indicated by a selector, the intermediate stops to be expected within the distance and the instantaneous car load. By means of call registering devices in the form of ten key keyboards at the floors, it is possible to enter calls for destination floors, so that at the time of calculation, the floor calls and the car calls are available simultaneously. The calculated lost time sum, also called servicing costs, is stored in a cost memory provided for each elevator. During a cost comparison cycle, the servicing costs of all elevators are compared with each other by way of a cost comparison device where in each case an assignment instruction can be stored in an assignment memory of the elevator with the lowest servicing costs which instruction designates that floor to which the respective car is optimally assigned in time.

Title: Tensioning method
Inventor: MIYASAKA KIYOTO
IPC: B21B39/00
Filed: 1984-05-02
Abstract: PURPOSE:To obviate breakage of a rolling material even if said material is rolled under high tension by applying additively tension to said material except the transverse ends thereof. CONSTITUTION:Upper and lower rolls 2a, 2b of pinch rolls 2 are shifted in the directions opposite from each other and the tapered part of the upper roll 2a is positioned to one end of the rolling material 3 and the tapered part of the lower roll 2b to the other end in the stage of rolling. The material 3 is grasped and tensed by the straight parts of the rolls 2a, 2b and is rolled while the additive tension is applied to the material 3. The transverse ends of the rolling material are not grapsed by the rolls 2a, 2b and therefore the additive tension does not act on the ends thereof. The possiblity of the sheet breakage occurring in edge crack during rolling is eliminated by such method and since the average tension is exerted over the entire width of the rolled part, the high-tension rolling operation is made possible safely and surely.

Title: Ceramic lid for semiconductor package
Inventor: KIMURA KAZUO
IPC: H01L23/02
Filed: 1993-03-23
Abstract: PURPOSE:To prevent scattering of melted solder, generation of void in the step of soldering a lid. CONSTITUTION:A groove 5 for holding flow of gas between an interior and an exterior of a package is provided on a solder layer 4 of a lid 1 when a package body 11 is covered with the lid 1. The sectional area of the groove 5 is gradually increased from inside to outside of the lead 1 in the case of W1>W2 of its width. Since gas in the package to be expanded in a soldering step is externally discharged from the groove 5, an increase in an inner pressure is prevented, and scattering of the solder is eliminated. Since the groove 5 is fill with the melted solder from narrow inside of the width W2 to a wide outside of the width W2, gas is not enclosed in the step, and hence no void is generated.
