Title: Helical scan magnetic recording and reproducing device
Inventor: HASEGAWA TSUNAO
IPC: H04N5/78
Filed: 1985-04-17
Abstract: PURPOSE:To trace accurately only a prescribed area of the track of a magnetic tape which is driven at a high speed and to shorten the retrieving time, by driving a rotary head in its width direction in some period and having no drive of the head in the remaining period. CONSTITUTION:In a retrieving mode a drive signal generating circuit 5 produces a sawtooth wave signal in a PCM area within a period during which the rotary heads 1 and 2 (A, B) trace a magnetic tape from its lower end through the upper end. These sawtooth waves are supplied to drive means 3 and 4 via drivers 6 and 7, and both heads A and B are driven. Then a track is traced from its lower end through the termination part of the PCM area by the sawtooth wave signal. Hereafter both heads are equal to each other when they are not driven by the sawtooth wave. Therefore, the video information recorded on a video area is reproduced with noises. While the code information recorded on the PCM area can be reproduced with no noise.

Abstract: PURPOSE:To avoid the generation of bumps due to a stress, which is caused by a crystal grain boundary oxidation in a phosphorus-doped polycrystalline silicon layer, and to contrive a flatterning of the surface of the silicon layer by a method wherein a predeposition using a high-temperature and short-time annealing treatment is applied. CONSTITUTION:An insulating layer 2, which is used as a surface insulating layer and consists of SiO2, is formed on a substrate 1 consisting of single crystal silicon and the formation of a phosphorus-doped polycrystalline silicon layer is performed on this layer 2. In this case, an intrinsic polycrystalline silicon layer or an amorphous silicon layer 13 is deposited and formed on the layer 2. This substrate is placed on a loader 12 and is introduced in a light-transmitting furnace 11. Phosphorus-containing gas is introduced in the furnace 11 and the substrate is heated for a short time of 1200 seconds to one second at a high temperature of 900 to 1300 deg.C using light irradiation from lamp annealing means 14, such as infrared lamps or the like. By such a way, a phosphorus-doped polycrystalline silicon layer 23 is generated in the polycrystalline or amorphous silicon layer 13 and at the same time, an SiO2 oxide film 24 is formed. After that, the film 24 is removed and a flat phosphorus-doped polycrystalline silicon layer 23 is formed.

Title: Bushing
Inventor: TSURUMI TOYOAKI
IPC: H01F27/12
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To prevent heat radiation near an oil-immersed terminal by forming grooves composing a cooling fin of the oil-immersed terminal of a bushing in a manner that the depth near the connection conductor is made shallow and the depth of each groove is made deeper step by step toward the center of the conductor. SOLUTION: Main flow 6 of electric current flows along an oil-immersed terminal 5b to a connection conductor 4 and while leaving the part along the flow of a cooling fin 7b grooves of the cooling fin 7b are formed by using the parts out of the main flow. Consequently, since no significant difference is caused between the surface area of the oil-immersed terminal 5b and the surface area of a conventional oil terminal, approximately same cooling function can be obtained and abnormal electric resistance increase can be prevented. Moreover, since the electric conductive route is sufficiently retained, the temperature elevation due to electric current concentration is reliably moderated. Furthermore, the strength against the vibration of the cooling fan can be improved by using a structural aluminum material provided with a mechanical strength for a center conductor of the bushing.
