IPC: H01F38/14
Filed: 1991-09-03
Abstract: PURPOSE: To obtain a rotary transformer having many channels combined with a compact structured rotating signal transmitter. CONSTITUTION: The rotating transformer has an inner core 3 surrounded with an outer core 5. These cores 3, 5 are ferromagnetic rotating hollow blocks mutually rotatable round a common axis 9 with an air gap 7 left therebetween.

Filed: 1987-09-08
Abstract: PURPOSE:To prevent the occurrence of black solid copies caused by exposure defects, by providing a light emission detecting means detecting that an exposure lamp normally emits light and operating an eraser provided ahead of a developing unit over the full width of a photosensitive body when light emission is not detected. CONSTITUTION:When an original is fed to a contact glass 102, recording sheets of size suitable for said original are fed from trays 113 - 115. In parallel with the feeding of recording sheets, the exposure lamp of an exposing device 101 lights up to rotate a photosensitive body 107, and latent images in response to the original contents are formed on the surface of the photosensitive body. When the light emitting lamp does not emit light when exposure is required, the eraser 109 provided ahead of a developing part 110 fully lights up, and an electrostatic charger 108 removes electrified charges on the surface of the photosensitive body 107. As a result, the developing part 110 prevents toner from sticking to the surface of the photosensitive body 107, thereby eliminating black solid copies.

Title: Method and apparatus for cooling electronic device
Inventor: AKAMATSU NORIO
IPC: H01L23/467
Filed: 1990-08-28
Abstract: PURPOSE:To effectively radiate heat generated from a device and reduce malfunction and trouble through prevention of migration of dust into a device by covering the surface of an electronics device with a cover and allowing a fluid to flow into the closed space between cover and device. CONSTITUTION:A cooling cover 2 is attached on a package 1 of a heat generating device. A cooling cover 2 is provided with an input part 3 and an output part 4 for a fluid (liquid or gas) for the cooling purpose. Heat generated from the package 1 of the heat generating device is absorbed by the fluid flowing from the input part 3 and this fluid is exhausted from the output part 4. While a current flows into the heat generating device passing a pin 7, namely while an electronic device including the package 1 is turned ON, the fluid always flows from the input part 3 and is exhausted after absorbing the heat from the outputpart 4. Since the fluid passes the part near the surface of the package 1 of high heat generating device, the generated heat can be absorbed effectively and radiated.

Abstract: PURPOSE: To increase the size of an exchange bias by providing a thin layer of antiferromagnetic material contact with thin MR layer of a ferromagnetic material and the thin layer of mutual diffusion material in contact with the layer of the antiferromagnetic material. CONSTITUTION: The magnetoresistive(MR) sensor 10 is provided with thin MR layer 12 of the ferromagnetic material spread only on a central active area 11. The thin layer 14 of the antiferromagnetic material is stuck so as to be brought into boundary contact with the MR layer 12. Thus, anisotropy in the one direction occurs by exchange joint between both ends of the boundary between both layers 12, 14, and the movement of the MH loop of the MR layer called as a vertical direction exchange bias magnetic field occurs. A horizontal direction bias is generated by a soft magnetic field layer (not shown in figure) separated from the MR layer by a thin non-magnetic spacer layer (not shown in the figure) for preventing magnetic exchange between the MR layer 12 and a soft magnetic bias layer.  A conductor lead 16 is constituted of a layer structure of a Ta thin film 20, an Au, etc., good conductor layer 22 and a Ta thin capping layer 24.
