Title: Method for selecting transmission path between lans
Inventor: SANO MAKOTO
IPC: H04L12/40
Filed: 1994-01-27
Abstract: PURPOSE:To select a path offering a minimum transmission time when plural paths leading to a destination are in existence in a network in which plural LANs are interconnected via routers. CONSTITUTION:A transmission node (work station 7) sends a connection open request packet to a destination node (server 8) via all paths (1), (2) in existence between both the nodes. Each of routers R1-R6 in a path receiving said packet records data such as an input time of said packet to a concerned router, an output time from the router, and transfer speed of lines 4-6 till a succeeding router to a prescribed recording part in said packet and transfers the packet to a succeeding router. Upon the receipt of the packet, the destination node copies the data in the recording part to a reply packet and returns the reply packet to the transmission node. Upon the receipt of the reply packet, the transmission node selects a path offering a minimum transmission time based on the data and sends the data by using the selected path afterward.

Filed: 1983-02-18
Abstract: PURPOSE:To detect exactly a position without receiving the influence of a change in temp. by stopping the counting of the ultrasonic pulses from a magnetic field generating means provided at every prescribed interval in a waveguide when the different ultrasonic pulses from a movable body arrive. CONSTITUTION:When the pulse current from a pulse generator 4 is supplied to the core wire of a waveguide 1, ultrasonic pulses are generated from stationary permanent magnets 20 provided at a constant interval to the waveguide 1.

The exact detection of the position is accomplished by such digital constitution without receiving the influence of the change in the propagation speed of the ultrasonic wave owing to a temp., etc. and without receiving the influence of a change in temp.

Title: Thin film magnetic head
Inventor: NAGURA HAJIME
IPC: G11B5/187
Filed: 1984-02-15
Abstract: PURPOSE:To reduce contour effect of a magnetic head, by applying a multilayer structure in which soft magnetic thin films which are piled up on a non-magnetic substrate to make a core and interlayer materials are alternately piled up at the same time, making the thickness of the interlayer materials <=1/10 of the gap length. CONSTITUTION:Soft magnetic thin films 5a, 5b,...5f which are piled up of a non- magnetic substrate and which become the core of the magnetic head of this invention have a multilayer structure in which the soft magnetic thin films and interlayer materials 6a, 6b, 6c, and 6d are alternately piled up. The thickness of the interlayer materials 6a-6d is set to 0.005mum which is <=1/10 of the gap length 0.3mum. Moreover, the thickness of the soft magnetic thin film nearest to a gap 7 is set to 5mum and the thickness of the other magnetic thin films is successively reduced 1mum by 1mum as going farther from the gap 7. Therefore, the contour effect (unevennees in reproduced output) can be reduced and, at the same time, loss in eddy current can be reduced by successively reducing the thickness of the soft magnetic thin films. As a result, a desired output can be obtained.

Inventor: FUJISHIMA NAOTO
IPC: H01L29/06
Filed: 1993-02-15
Abstract: PURPOSE:To construct a high breakdown strength MIS field-effect transistor which attains reduced on-resistance through high-integration while assuring sufficient breakdown strength of an element. CONSTITUTION:On a well layer 100 formed an the surface side of a semiconductor substrate 101, the first and second area parts 103 and 102, facing each other, with a part of the semiconductor substrate 101, selectively left as it is as a well non-formation area 101a, in between, separately exist. Since a flat protrusion-like base corner part, where electric field is easy to concentrate, of a base layer 105 is surrounded by the semiconductor substrate 101 and the first area part 103 that becomes depleted at a relatively low apply voltage, electric field concentration into this part is relaxed, so, with a smaller radius of curvature at a base corner part, higher integration and lower on-resistance of elements becomes possible, while high breakdown strength being kept.

Filed: 1990-02-05
Abstract: PURPOSE:To decrease the overhead of the memory management executed by an operating system (OS) and to execute the other space access with an application by providing a means for releasing the suppression of a mechanism for generating forcibly a TLB fault. CONSTITUTION:When a memory access instruction is issued in order to access the other space by an application, an address conversion buffer (TLB) fault is generated forcibly. Subsequently, by deriving the real address of the other space by a dynamic address converting (DAT) mechanism and storing it in a TLB 1, the generation of the TLB fault is suppressed. Also, the subsequent memory access to the other space is accessed by the real address stored in the TLB 1, and in the end condition of the access, the suppression of the genera tion of the TLB fault at the time of accessing the other space is released. In such a manner, the overhead of the memory management by an OS is de creased, and the other space access by the application can be executed.

IPC: G11B15/093
Filed: 1989-02-03
Abstract: PURPOSE:To prevent such a hindrance as a running failure, etc., to be caused by a tape sag by constituting this cassette tape deck so that the time extending from the rotation stop of a reel axis to the tape end detection can be set long. CONSTITUTION:A pickup lever 54 is brought to fist stage centering by an outer cam of a detection gear 49 in a state that it is stopped by a stop of a reel axis 3, and thereafter, brought to final stage centering and executes a tape end detection, and a switching operation of a switching lever. Accordingly, the time extending from the rotation stop of the reel axis 3 to the tape end detection becomes longer, that is, according to the constitution shown in this figure, unless the gear 49 is rotated by >=360 deg., the tape end detection cannot be executed. In such a way, in the case when a sag is generated in the tape, the tape end detection is executed in a state that the tape is wound completely to one reel axis side, and an erroneous detection, a malfunction of switching, etc. can be prevented.

Abstract: PURPOSE: To decide how the parameter of a device is optimized and to solve the defect of relative technique by discriminating or recognizing technique for increasing a possibility in the detection of the characteristic of a radiation which is mutually activated with a storage medium in a magneto-optical device. CONSTITUTION: The delay and the angle of a wavelength plate 16 in an optical path are decided by a method where a signal is made to be max. to a noise ratio generated by radiation detecting equipments 18 and 19. Two equations are calculated for the parameter of the wave length plate, one equation is the one as against the delay parameter of the general or the whole wavelength plate and the other equation is the one as against the angle with the delay curved line of the general or the whole wavelength plate 16. They are plotted in order to discriminate or recognize a value as against the parameters. In this case, a deviation from the optimum signal to the noise ratio is small.
