Title: Method of winding bar material
Inventor: KUROKAWA TOMOAKI
IPC: B65H54/76
Filed: 1978-08-29
Abstract: PURPOSE: To improve coil compacting ratio by controlling rotational speed of pinch roll in consideration of centrifugal force acting to bar material to be coiled, according to predetermined amplitude and cycle and absorbing loop produced by that control in a looper.  
     CONSTITUTION: Bar material 20, after exitting rolls 15 on a rolling stand, is sent from a guide pipe 17 through loopers 18, 18 and pinch rolls 16 to a reel 10 to be wound into a laminated coil. The rotational frequency NR of the reel 10 coincides with the speed V of the bar material at the position of roll 15. While the rotational speed of the pinch roll 16 varies cyclically, the average rotational speed N p  is matched with the speed V of the bar material and the varying cycle T is obtained from equation (III). The amplitude A is obtained from equation (IV) by multiplying a factor k which corrects the variation due to the centrifugal force acting to the bar material. These computation is carried out by apparatus 44, 45 to control the rotational frequency of the pinch roll 16 by a speed control 52 for a motor 51.

Title: Present position display device for moving body
Inventor: HIJIKATA YOICHI
IPC: G08G1/0969
Filed: 1992-04-24
Abstract: PURPOSE:To realize the correcting operation of the present position without bringing about problems of drop-out of candidates, subtleness of threshold setting, precedence of parameters, etc. CONSTITUTION:Roads L0 to L5 as map matching objects are retrieved from map data, and each road is evaluated on a plane theta'-d' where theta' is the standardized value of the angle formed by the locus of an inferred position and the road and d' is the standardized value of the length of a perpendicular drawn from the inferred position to the road. The road L0 from which a distance R0 to the origin is shortest out of roads L0 to L5 is selected as the matching road and is used for calculation of corrected coordinates. Since geometrical relations between the locus of the present position and each road are evaluated in the multidimensional space consisting of plural parameters, drop-out of candidates and subtleness of threshold setting are eliminated, and it is unnecessary to take the precedence of parameters or the like into consideration.

Title: Kettle with efficiency heightened
Inventor: MAKIGI KOUJI
IPC: A47J27/21
Filed: 1995-03-16
Abstract: PURPOSE: To heighten the thermal efficiency and enable the quick water boiling by fitting a kettle body with a cover and thus making the heat stay in a void space between both of them. CONSTITUTION: Filled with water, the kettle body is mounted on a cooking stove, which is then fired. Because the kettle body was not equipped with any cover, the hot air ascended around it, so that a considerable quantity of heat was lost without heating the kettle. Therefore, by fitting a cover 1 to the kettle body with, the hot air, which was lost due to its ascension, can stay and be used for heating the kettle. The ordinary kettle without cover needed the duration of 7 minutes 15 seconds to boil the water of 750cc. However, the kettle with cover 1 now needs the duration of 4 minutes 50 seconds to boil the water of equal 750cc. Therefore, the thermal efficiency is heightened, so that the water can be boiled at a low fuel cost and in a short time.

Abstract: PURPOSE:To prevent the increase of conductor thickness due to plating, and to improve the accuracy of the formation of a circuit and the printing accuracy of a solder resist by previously sticking a film on the surface of a metallic foil prior to the plating treatment of the inwall section of a through-hole. CONSTITUTION:Films 4 are stuck on the surfaces of the foils 2 of a metal-clad laminated board 3 composed of a multilayer-board base material layer 1 and metallic foils 2 as outermost surfaces. Films having plating resistance and can simply be stuck and peeled are used as the films 4 at that time.

Circuits 11 having patterns required are formed on a through- hole plating-treated printed wiring board 10 formed through a means such as etching. Accordingly, the increase of conductor thickness due to plating treatment can be inhibited, thus improving the accuracy of the formation of the circuits through etching, etc., and the printing, etc., of a solder resist.

Abstract: PROBLEM TO BE SOLVED: To always arrange the position of the temperature detection element of a fixing roller at a prescribed temperature detecting position even when the fixing roller is rotated by forming so that the supporting length of an elastic holding member by a supporting member on an upstream side is longer than the supporting length thereof by a supporting member on a downstream side. SOLUTION: The first supporting member 301 is provided with the second supporting member 302 on the upstream side in the rotating direction of the thermal fixing roller 202 and the third supporting member 304 on the downstream side. The supporting length of the elastic holding member 309 by the second supporting member 302 is formed to be longer than the supporting length thereof by the third supporting member 304. Since the third supporting member 304 is formed so that the holding length thereof L1 for holding the holding member 309 is shorter in such a way, a certain elastic force possessed by the holding member 309 acts and the temperature detection element 310 provided at the surface of the holding member 309 is arranged at the prescribed position through a belt-like member 312. Thus, temperature can be precisely detected.
