Title: Toner concentration detector for developer
Inventor: IMAFUKU TATSUO
IPC: G01N27/72
Filed: 1986-02-28
Abstract: PURPOSE:To detect accurately toner concentration by providing a developing device with a magnet arranged oppositely to developer and a pressure sensor arranged between the magnet and the developer so that its detecting surface is abutted upon the magnet. CONSTITUTION:The pressure sensor 12 outputs a signal corresponding to attracting force between the developer 22 and the electro-magnet 11, and at the time of detecting the attracting force exceeds a prescribed value, decides the reduction of toner concentration in the developing device 20, so that a toner feeding roller 31 in a toner hopper 30 is rotated. Consequently, toner 32 in the hopper 30 is replenished to the developing device 20 and the toner concentration in the developing device 20 is increased by the replenishment of the toner, so that the magnetized ratio of the developer 22 is reduced and the attracting force between the developer 22 and the electro-magnet 11 is reduced. The pressure sensor 12 detects said status and stops the rotation of the roller 31. Thus, the toner concentration in the developing device 20 is controlled at a prescribed value.

IPC: H02K3/04
Filed: 1993-03-05
Abstract: PURPOSE:To allow high speed rotation without increasing power consumption through simple structure by providing an intermediate terminal between input and output terminals and feeding the intermediate terminal with a predetermined driving voltage. CONSTITUTION:Driving coil 23 of a capstan motor is provided with input and output terminals 41, 42, respectively, at the start-of-winding and end-of-winding. An intermediate terminal 43 is also provided between the input and output terminals 41, 42. These terminals 41-43 are formed by peeling off the outer film of a self-fusion wire. When a driving voltage is applied between the input and output terminals 41, 42, the capstan motor rotates at a predetermined r.p.m. When same voltage is applied between the input and intermediate terminals 41, 43, the motor rotates at a higher r.p.m. Consequently, r.p.m. of the motor can be increased without increasing the driving voltage.

Title: Method for casting short square steel ingot
Inventor: YASUMOTO KUNIO
IPC: B22D7/00
Filed: 1987-02-28
Abstract: PURPOSE:To prevent the base cracking of a short square steel ingot by inclining a casting mold and molding board in such a manner that only one of the ridge or vertex of the base is lowest, starting pouring, returning the molding board to a horizontal position after a molten steel covers the base of the casting mold and complete the pouring. CONSTITUTION:While the casting mold 2 is held fixed, the molding board 1 is inclined and the molten steel 5 is poured to the base on the lower side at the time of casting the short square steel ingot having <=1 (H/A<1/2=1) ratio of the square root of a height H and base area A. The rising speed at the beach 6 is lowered by lowering the pouring speed during the time when the molten steel surface rises, by which the shrinkage of a solidified shell is absorbed to the lower side and the cracking is prevented. While the molding board is returned to the horizontal position in the second half of the pouring, the pouring is continued and finally a heat insulating material is charged into the mold to complete the casting. The base cracking of the ingot is thus prevented and the extremely thick single product is produced at a high yield.

Title: Production of back skin for glove
Inventor: YAMADA TSUGUZOU
IPC: C14C9/02
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain a back skin having a smooth beautiful surface and used for gloves by polishing the surface of a back skin in the production of a back skin for gloves by shaping the surface of a leather of e.g. a kangaroo. SOLUTION: A leather (3mm thick) of e.g. a kangaroo is allowed to absorb about 30wt.% water and is stripped of its surface skin with a shaping machine or by cutting to obtain a back skin (0.5mm thick) in a state containing about 20wt.% water. The back skin, desirably in the state containing water, is polished with water paper. As a result, the fluffs on the surface of the back skin are removed. The fibers under the surface do not rise as fluffs because the back skin is polished in the wet state. If required, the polished back skin is treated with an oil. This makes the back skin soft. The back skin can give golf gloves, etc., having good touch and feeling of use.
