Filed: 1985-09-20
Abstract: PURPOSE:To aim at completely automating the wind-up of scraps and at enhancing the efficienchy of a continuous steel strip processing line, by providing an opening and closing means for limiting the stream of long length edge scraps of steel strips, and a cutting means for cutting the long length edge scraps. CONSTITUTION:Edge scraps 3 which are produced by processing a steel strip 3 with the use of a side trimmer 1, are led into a scrap chute 4 formed of an inlet side stationary chute 21 having an inclined front section, an outlet side tiltable table 13 connected to the front end of the chute 21 and an auxiliary table 16. When the leading end of each edge scrap 3 comes to a mandrel 7 after sliding on the bottom surface of the scrap chute 4, a photoelectric device detects the leading end of the scrap 3 to close a shutter 14 for clamping the leading end of the edge scrap 3. Then, the shutter 14 is oepened, and the mandrel 7 is driven to form a bell 9. When the ball grows up to a predetermined size, the shutter 14 is closed while the tables 13, 16 are rotated counterclockwise so that a cutter 17 cuts the edge scrap 3. With this arrangement, no manual labor is required, and therefore it is possible to automate the wind-up operation of the scrap.

Title: Display control method for icon
Inventor: KUNIHIRO YUJI
IPC: G06F3/0487
Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To improve operability and decrease misses by counting the frequency of selection of each icon in the operation period of a device, setting priority which is higher and higher as the counted frequency is larger and larger, and varying the recognition area of the icon according to the priority and varying the area according to the frequency of selection. SOLUTION: An icon having high priority has its recognition area set larger than an icon which has low priority. The hit frequency of each icon is counted. The priority is varied according to the frequency at which each icon is operated to give higher priority to an icon which is higher in hit frequency. The recognition area of each icon is varied corresponding to its corrected priority. For example, icons i1 and i2 which are not varied are varied in priority and then varied into icons i'1 and 1'2 . If a recognition area overlaps with the recognition area of another icon when varied, the size before it overlaps is employed.

IPC: C02F1/48
Filed: 1983-11-07
Abstract: PURPOSE:To remove impurities in supply water in a short time by placing plural heat transmit tubes with both ends fixed to tube plates at the inside of a cylinder having the tube plates at both ends, and providing a steam inlet tube, an outlet tube, and electric power source terminals at the inside of said cylinder. CONSTITUTION:An electric current is passed appropriately during operation between electric power source terminals 14 and 14a for exciting electric heating tubes provided to tube plates 11 and 11a on both ends. When a heat transmit tube 13 is excited and steam is sent in from a fluid heating steam inlet tube 15 to elevate the temp. of a liquid, granular metallic impurities in supply water are deposited on the inner surface of the heat transmit tube 13. The phenomenon is attributable to the fact that the granular metallic impurities in the supply water such as hematite and magnetite are easily adhered to a magnetic body and easily deposited at 180-260 deg.C. The capacity can be increased by increasing the surface area of the heat transmit tube 13 and the magnetizing current.

IPC: G03G15/09
Filed: 1981-12-24
Abstract: PURPOSE:To increase the amount of developing toner per unit area without increasing the number of developing rolls by affording a ruggedness to the leading edge of a developer flow rate control plate and thus forming the surface of  a developer sticking to the developing rolls before a developing nip in an axially  rugged pattern. CONSTITUTION:Since the flow rate controlling plate 4 has a rugged leading edge surface 4a, a developer (a) on the surface of the developing roll 2 after passing through the flow rate control plate 4 has a rugged pattern conforming to the controlling plate 4. This rugged pattern is smoothed in a developing nip area A and in this process of smoothing, a turbulent flow is caused by diffusion of a projecting part developer a' to both end recessed parts a'' and a'' and the inflow of a projecting part developer at a recessed part a''. Consequently, the amount of a developer contacting the surface of a photoreceptor increases to obtain more developing toner per unit area.
