Title: Method for controlling magnetic head in magneto-optical disk recording and reproducing device
Inventor: AOKI TAKESHI
IPC: G11B11/10
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To prevent a magnetic head from touching the surface of a magneto- optical disk by displacing the magnetic head to a position for recording operation when the number of revolution of the magneto-optical disk runs up to the number at which the magnetic head can be floated. SOLUTION: When the revolving motion of a spindle motor starts it is discriminated whether the number of revolution runs up to a prescribed number or not, namely, the number of revolution necessary for a magnetic head to float by the air flow generating by the rotation of the magneto-optical disk. When the number of revolution reaches the prescribed number, it is discriminated whether wobbling surface occurs in the rotation of the magneto-optical disk. If presence of a wobbly surface is discriminated, the magnetic head is moved to a prescribed position on the inner circumferential side of the magneto- optical disk. When the movement to the prescribed position is discriminated, the magnetic head is transferred to the operating position.

Title: Preparation of rare earth element-co type thin plate magnet
Inventor: SAKAI ATSUSHI
IPC: B22F3/02
Filed: 1983-10-31
Abstract: PURPOSE:To prepare a rare earth element-Co type thin plate magnet free from heat strain in a mass production system, by alternately stacking lumpy plates each obtained by applying compression molding to a rare earth element-Co alloy powder in a magnetic field and slightly larger heat resistant metal plates and sintering the whole before cooling. CONSTITUTION:An alloy powder containing a rare earth metal such as Sm and Co is molded into a thin plate form under pressure in a magnetic field to prepare a lumpy plate 1. This lumpy plate 1 and a heat resistant metal plate 2 made of stainless steel having a size protruded from the lumpy plate are alternately stacked while a mold platen 4 is placed on the resulting laminate 3 which is, in turn, sintered while inert gas is injected from gas blow-out orifices 5 provided to the mold platen 4. In this case, the heat resistant metal plate 2 functions as a heat disspating plate. After sintering, the sintered one is cooled at a cooling speed of about 2 deg.C/sec. By this method, a rare earth metal-Co type thin plate magnet excellent in magnetic characteristics can be obtained.

Title: Transmission buffer data storage method and transmission buffer data storage device
Inventor: UEDA TAKESHI
IPC: H04L12/40
Filed: 1994-08-31
Abstract: PURPOSE: To reduce transfer processing of transmission data by a transmission buffer when a protocol header is added. CONSTITUTION: Transmission data are stored so as to be packed backward (toward tail end address AE) in a transmission data storage area provided to a transmission buffer together with a management information storage area having data head address information SA. Idle areas not in use are obtained in preceding areas of the area SD in which the transmission data are stored. Since a protocol header is stored in the idle area, it is not required to transfer the transmission data.

Title: Claw feed device
Inventor: MANIWA TOMOYOSHI
IPC: F16H31/00
Filed: 1985-09-20
Abstract: PURPOSE:To contrive to improve an operation speed by so composing a device that a driving lever capable of reciprocation in the direction of shaft center and reciprocation round shaft center may have a claw with an IC top face press plate installed thereon, in a claw feed device for use in IC transport. CONSTITUTION:A feed claw 2 moves in the a, c direction along a guide rail 1 as the result of a reciprocation of a link bar 3 in the arrow a' or c' direction. And by the reciprocation of the link bar 3 in the arrow b' or d' direction, the feed claw 2 moves upward or downward in the arrow b or d direction. Hereby, IC is feed pitch by pitch. And then when the feed claw 2 is lowered, a press plate 8 comes in contact with the top face of IC and presses it down. Consequently IC is moved by the feed claw 2 while being pressed by the press plate 8, therefore the inertial movement is prevented even at the stoppage. In this way, the improvement on the operation speed can be contrived without causing any sliding movement resulting from the inertia of IC even if the operation speed is raised.

Title: Speed-detecting apparatus
Inventor: CHIBA KOJI
IPC: G11B15/46
Filed: 1994-08-31
Abstract: PURPOSE: To accurately calculate a correct running speed of a tape by a rotating speed of a single reel, by counting a count of pulses generated proportionally to the number of revolutions of the reel and detecting the diameter of the reel of the tape. CONSTITUTION: The rotation period of the reel is detected by a period detector 31 from pulse signals output by a signal generator 30 in proportion to the rotating speed of the reel. The diameter of the reel of a tape 1 is obtained by a diameter detector 32 from the rotation period and a predetermined running speed Vo of the magnetic tape 1. A diameter change calculator multiplies the counted number of pulses counted by a counter 33 by the thickness of the tape 1, thereby calculating a changing amount of the diameter of the reel of the tape 1. The changing amount is added to the reel diameter by an adder 35.  A reference value for the period is calculated by a reference period calculator 36 from the added value and the speed of the predetermined tape 1 and fed to a speed calculator 37, where the running speed of the tape 1 is calculated with the use of the output of the cycle detector 31 and the speed of the speed of the predetermined tape 1. Accordingly, the correct reel diameter and the correct running speed of the tape can be obtained only from a rotating speed of a single reel.

Title: Injection fuel control method of internal-combustion engine
Inventor: TOMITA KAZUO
IPC: F02D41/12
Filed: 1981-12-21
Abstract: PURPOSE:To prevent an abrupt torque increase after restarting the fuel injection and to save the fuel consumption by detecting the engine speed and by injecting the minimum fuel required for not causing an ignition misfire when the fuel injection is restarted during an idling time after deceleration. CONSTITUTION:Signals from an engine speed sensor 1, idle switch 2 and timer 3 of an electronic fuel injection control device are input into ECU5 through an input unit 4, and ECU5 inputs fuel injection stop/restart commands into an injection valve 7 through an output unit 6. In this case, the relationship between the engine speed N and the minimum fuel injection quantity taum required for not causing an ignition misfire at each engine speed N has been previously determined. When the fuel injection is restarted, the engine speed N is detected then the corresponding taum is determined, and taum is connected from a time TF to a time TF' for fuel injection, thus a minor combustion is immediately restarted at the time TF and the fuel injection quantity is increased to tauf at the time TF', thereby the desired object can be attained.

Title: Magnetic permeability measuring instrument
Inventor: SENDA MASAKATSU
IPC: G01N24/00
Filed: 1990-08-06
Abstract: PURPOSE:To make magnetic permeability measurement achievable even in a high frequency range higher than 100 MHz by installing a resonator installed in a sample coil and a soft magnetic substance as a measured sample installed in and around this sample coil, respectively. CONSTITUTION:When an electric current of frequency omega is generated out of a generator 1, a radio frequency magnetic field of the frequency omega is impressed on a sample coil 3, a resonator 7 and a soft magnetic film sample 6 by an RF coil 2. When an external magnetic field H, satisfying a specific condition, is impressed, the RF magnetic field is strongly attracted by the resonator 7. The state of this resonance absorption is observed as an absorption spectrum by a receiver 5. In use of a resonance phenomenon, magnetic permeability measurement for a soft magnetic film is carried out. Several types of resonators Q different in nuclear quadruple resonance frequency are selected, through which frequency on impedance of the sample coil 3 in time of taking in the soft magnetic film sample 6 is securable, thus the frequency dependency of relative magnetic permeability is grasped. In the nuclear quadruple resonance and the magnetic resonance, their resonance frequencies are extended wide from several to hundreds of MHz according to the resonator, so that with the resonator M properly selected, relative magnetic permeability measurement at this frequency range is made possible to be done.
