Title: Thresher
Inventor: SHIGEMATSU KENJI
IPC: A01F12/18
Filed: 1989-07-14
Abstract: PURPOSE:To prevent clogging of dust-exhausting port with waste straw, etc., and improve dust-exhaustion treatment capacity by supporting a feed end of a dust-exhaustion treatment drum in a dust-exhaustion treatment chamber with a bearing and placing the free delivery end of the drum close to the dust- exhausting port, thereby widening the dust-exhausting port. CONSTITUTION:A threshing drum 1 is placed in a threshing chamber 3, a threshing mesh 2 is placed under the drum and a dust-exhausting port 4 to exhaust the dust in the product threshed in the threshing chamber is placed at the delivery end of the threshing chamber 3. The dust-exhausting port 4 is connected to a dust-exhaustion treatment chamber 5 for scraping and treating the dust exhausted from the dust-exhausting port 4. A dust-exhaustion treatment drum 6 is placed in the dust-exhaustion treatment chamber 5, the feed end of the dust-exhaustion treatment drum 6 is supported by a bearing and the delivery end of the drum is made to be a free end and placed close to a dust- exhausting port 7. Since there is no bearing of the dust-exhaustion treatment drum at the dust-exhausting port 7, the port 7 can be widely opened and the waste straws, etc., in the exhaust dust can be smoothly discharged from the dust-exhausting port 7.

Title: Method and apparatus for dicing
Inventor: TSUCHIDA KIYOSHI
IPC: H01L21/301
Filed: 1987-07-24
Abstract: PURPOSE:To reduce scattering of cutting scraps falling with washing water and to reduce adhesion of the cut scraps on a wafer, by facing a cut groove forming face of the wafer downward and carrying out dicing by rotating a rotating blade from the bottom of the wafer. CONSTITUTION:A wafer 2 is held under such a condition that the cut groove forming face is faced downward, and dicing is carried out under such a condition that a rotating blade 4 is rotated and washing water is sprayed from a nozzle 7 around the part of the wafer 2 where the cut groove should be formed. Cut scraps produced by dicing are scattered in the opposite direction to the forwarding direction of the rotating blade 4 by the flow of the washing water 8 and the centrifugal force of the rotating blade 4. The cut scraps fall down due to the dead weight but do not fall down on the wafer 2 because the wafer 2 is positioned above the rotating blade 4. Even if the cut scraps with water drops of the washing water adhere on the main surface of the wafer 2, the cut scraps fall down by the dead weight owing to vibration of dicing and so on, and remaining of the cut scraps on the main surface of the wafer 2 is thereby reduced.

Abstract: PURPOSE:To ensure the working of a multi-tasking system without destructing a synchronizing mechanism and to process the tasks in the order of higher priorities, by processing the tasks of higher priorities with preference only with management of the priority of each task even in case the I/O processing is involved. CONSTITUTION:When the task of processing algorithm delivers a system call P(S) to an operating system OS, a CPU 1 gives a command to a semaphore managing part 6 and the semaphore designated by a semaphore part 3 is decided. Then this semaphore if decided off is turned on and the flag of a flag part is turned on to complete the processing. While if said semaphore is kept on, the part 6 gives a command to an address generating part 4 to produce an address so that the corresponding task information is selected within a semaphore-only task control part 2. A comparator 7 compares the priority information given from the part 2 with the task priority given from the CPU 1. Then a signal is sent to an interruption control part to perform the interruption processing when the priority of the task produced the call P(S) is higher than the priority information of the part 2.

Filed: 1985-08-23
Abstract: PURPOSE:To prevent data from damage due to the abnormality of a synchronizing clock signal by detecting an index pulse or a sector pulse obtained from a magnetic disk device during the writing of data in a sector to inhibit data writing. CONSTITUTION:When writing data are written from a master processor 2 to a medium in a magnetic disk device 3, a magnetic disk control device 1 executes seeking operation to an objective track outputted from the processor 2. After the end of the seeking operation, a write control circuit 21 compares the sector address of read data (b) with a sector address stored in the circuit 21 through a bus (a). At the coincidence of the sectors, the circuit 21 sets up a write enable signal (h) in the coincident sectors and switches a synchronizing clock signal (c) to a writing clock signal (i). On the other hand, the signal (h) and an index/ sector pulse (f) are supplied to a write signal abnormality detecting circuit 22, and when abnormality is generated in the signal (c), outputs an error signal (g) to inhibit the output of a write signal (e). Thus, data can be prevented from damage due to the abnormality of the signal (c).

Title: Perpendicular magnetic recording medium
Inventor: AKIYAMA JUNICHI
IPC: G11B5/64
Filed: 1992-07-13
Abstract: PURPOSE:To suppress Barkhausen noises by forming a bias magnetic field- imparting film to the surface on the substrate side of a high-permeability magnetic film. CONSTITUTION:The bias magnetic field-imparting film 2 is formed on a substrate 1 and the high-permeability magnetic film 3 is formed thereon. Further, a perpendicularly magnetized film 4 for recording signal magnetization is formed thereon. An exchange interaction acts on the boundary between the bias film 2 and the high-permeability magnetic film 3 and the bias magnetic field is impressed to the magnetic film 3. As a result, the generation of the magnetic walls in the magnetic film 3 is suppressed and the Barkhausen noises are suppressed. A spacing layer, such as antiferromagnetic film, is not formed between the perpendicularly magnetized film 4 and the magnetic film 3 and therefore, the action of the thickness of the antiferromagnetic film as a spacing loss at the time of recording and reproducing does not arise. Consequently, the perpendicular magnetic recording medium having high recording and reproducing efficiency and high resolving power is obtd.

Title: Arrow pointer device
Inventor: HAMANO TAKAMASA
IPC: G06F3/0481
Filed: 1992-06-18
Abstract: PURPOSE:To obtain an arrow which can be discriminated at all times irrelevantly to the brightness of its background by generating an indication mark consisting of an outline and a core figure having a large brightness difference at a specific position in a presentation image. CONSTITUTION:As an example of a dot pattern of an arrow font, an arrow font in dot pattern which consists of longitudinally 16 2-bit pixels and laterally 16 pixels so that two arrow edge dots are black (corresponding to '00'), an arrow center part is white (corresponding to '01'), and parts other than the arrow are through (corresponding to '10') is stored in a ROM. The shapes of the black outline and white internal core need to clearly be discriminated. When the brightness of a circumferential image is low, the white part of the arrow makes an arrow indication position distinctive and when the brightness is high, the black edge part of the arrow makes the arrow indication place clear. The need for the white/black switching of the arrow is eliminated, so a white/black polarity changeover switch is unnecessary.

Filed: 1986-08-06
Abstract: PURPOSE:To form grooves and holes in different depth only through one-time mask alignment by one mask by projecting two kinds of focussing ion beams having different intensity, each giving an interrupting film the changes corresponding to the ion beams and ion-milling the interrupting film. CONSTITUTION:A heavy metal having large X-ray absorptivity such as a gold layer 13 and subsequently an aluminum layer 14 are evaporated onto a base layer 11 consisting of an silicon nitride film on the surface of an silicon substrate 10. The gold layer 13 prevents the transmission of X-rays when it has not less than fixed thickness, and functions as a stopping film through which X-rays in quantity corresponding to the thickness are transmitted when it has thickness less than that. When ions are driven to the gold layer 13 through the aluminum layer 14, gold and aluminum are converted into eutectic bodies 16 in response to the quantity of the driving, and the state in which the eutectic bodies are easy to be removed through etching is brought in a subsequent ion milling process. That is, the eutectic bodies 16 are removed through etching as the result of the ion milling process, and a groove 17 is bored while a groove 18 in which the gold layer 13 is left is formed at a position where there are little quantities of ions being implanted.
