Title: Image forming device with sheet feeder
Inventor: GOTO SHINJI
IPC: B65H29/60
Filed: 1989-06-27
Abstract: PURPOSE:To prevent duplicate feeding and a jam caused by manual sheet insertion in printing the second face by providing a sheet conveying path for returning the sheet fed from a sheet feed means to the sheet feed means again. CONSTITUTION:When the second face of a sheet is to be printed, a solenoid is excited to move a guide 32 to the two-dot chain line, and the sheet is conveyed by a roller 41 to the position where it can be fed by a sheet feed roller 31. When the sheet feed roller 31 is rotated, the feeding for printing the second face is started. Rollers 41 and 42 in a re-feed conveying path are driven by a pulse motor independently from other portions so as to convey the sheet at the same speed as the sheet conveying speed by the sheet feed roller 31. The conveying speed is accelerated, the sheet is brought into contact with a resist roller 23 then conveyed by the roller 23. Even if a sheet is inserted through a manual feed port when the second face is printed, this feeding is prevented by the guide 32, and no duplicate feeding occurs.

Filed: 1994-07-19
Abstract: PURPOSE:To obtain a boiling and cooling device, in which the rigidity of mounting surface of a heat generating body has been improved and the maximum heat radiating amount should not be limited. CONSTITUTION:A refrigerant tank 4, to which a heat radiator and a heat generating element are attached, and an inverter case 6 are connected by welding or brazing while a cooling fan is installed on the back surface of the heat radiator. An IGBT module 5 is clamped in two stages to the side surface of the cooling tank together with the inverter case 6.

Title: Manufacture of magnetic bubble detector
Inventor: IINO TOSHIO
IPC: G11C11/14
Filed: 1990-06-26
Abstract: PURPOSE:To prevent the coercive force of permalloy from being increased and an MR element from being disconnected and to enable stable contact by forming the MR element and an electrode film in vacuum while eliminating the step of the MR element with molybdenum, which is hardly dispersed thermally, as an electrode material in permalloy. CONSTITUTION:Molybdenum 61 of an electrode in contact with a magnetic bubble detecting element 5 (permalloy) has a property to be hardly dispersed thermally into the permalloy 5 even when being heated. Since there is etching liquid to dissolve only the molybdenum 61 without dissolving the permalloy 5, the electrode 61 (molybdenum) can be formed on the magnetic bubble detecting element 5 (permalloy). Therefore, the magnetic bubble detecting element can be formed as a plane and since the permalloy layer 5 (magnetic bubble detecting element) and the molybdenum film 61 (electrode) are continuously formed in vacuum, there is no danger of oxidation. Thus, the increase of the coercive force of the permalloy 5 and the disconnection of the MR element 5 can be prevented, and the reproducibility of contact between the MR element 5 and molybdenum electrode patterns 16 and 16 can be improved.
