Title: Flexible magnetic disk device
Inventor: IWAKURA MASAO
IPC: G11B17/34
Filed: 1987-10-28
Abstract: PURPOSE:To suppress flapping of a disk on its outer peripheral side and to obtain stable contact between a head and the disk by forming a recessed groove part parallel to a head moving course on an opposite surface of a stabilizing member to the disk and minimizing the depth of the recessed groove part on its outer peripheral side so far as not to allow the bottom of the recessed part to be in contact with the disk. CONSTITUTION:The recessed groove part 3b is provided in the middle of the opposite surface between 3a1 and 3a2 of the stabilizing part 3 to the disk as parallel to the radial direction of the disk 2, i.e., the head moving direction, whereas the recessed groove part 3b has on its side of the periphery of the disk 2 a slope 3b1 inclined in the direction of diminishing the depth of the recessed groove part 3b as well as in the radial direction of the disk 2. The airflow attending upon the rotation of the disk 2 enters into the recessed groove part 3b, where the air flows from the inner peripheral side of the recessed groove part 3b to the outer peripheral side. By this method, a positive pressure is generated on the outer peripheral part of the recessed groove part 3b, and an air damper effect due to the elasticity and viscosity of air is effective, so as to suppress the flapping of the disk 2, thus obtaining the stable contact between the head and the disk 2.

Abstract: PURPOSE:To enable the detection of the presence of exfoliation of a coating layer in a non-destructive, in an easy and reliable manner, by making an ultrasonic wave incident on the surface of a steel material with thick anticorrosive coating and by comparing an echo from the bottom of the steel material with a threshold value set in a prescribed manner. CONSTITUTION:A threshold value SL is set in accordance with an attenuation amount to which the condition of the boundary between a coating layer 2 of polyethylene or the like of a steel material 1 with thick anticorrosive coating and the steel material 1 is added, an echo obtained from an ultrasonic wave emitted into the material from an ultrasonic wave transmission-reception device 3 and received thereby is compared with the threshold value, and the result of comparison is displayed. The ultrasonic wave is not propagated when an exfoliated part 4 is vacuum, while the part shows high impedance when there is air in the part. When the exfoliated part 4 exists, an echo P3 to be obtained from the bottom of the steel material 1 in succession to a transmission wave P0, an echo P1 from the surface of the layer 2 and an echo P2 from the interface of the layer 2 with the steel material 1 does not appear. The presence of exfoliation of the coating layer is detected in a non-destructive, easy and reliable manner from the presence of said echo P3.

Title: Capacitor-charging device
Inventor: AZUMA MASAO
IPC: H02M3/335
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce the residual voltage of a resonance capacitor for prevention of overcurrent by fixing the start and finish of a gate signal into an inverter circuit at a switching element which runs current in one direction. SOLUTION: By alternately switching elements S1, S2 according to the resonance frequency of a capacitor 3 and a reactor 4, an inverter circuit 1 operates as a resonance inverter. The voltage of the resonance output is raised by a boosting transformer 5, rectified by a rectifying circuit 6, and applied to a load capacitor 7 to charge the load capacitor 7. At this time, a gate control circuit (not illustrated) permits a gate signal to start with a gate signal into the switching element S1 and to be completed with a gate signal into the element S1. The final gate signal permits the switching element S1 to have continuity, so that some current runs from the resonance capacitor 3, and residual voltage decreases, thus not generating overcurrent.

Title: Method of filling permanent magnet powder
Inventor: MATSUO YOSHIO
IPC: H01F41/02
Filed: 1987-10-28
Abstract: PURPOSE:To enable permanent magnet powder to be filled in a short time and to produce a magnet effectively, even if the opening area of a metallic mold is small, by employing a specific process in which an a.c. magnetic field having the gradient in the direction of the depth of the metallic mold is applied to the permanent magnet powder so that the permanent magnet powder is filled in the metallic mold by the magnetic attraction force. CONSTITUTION:When a current is caused to flow through a coil 28, an a.c. magnetic field having the gradient in the direction of the depth of a metallic mold is formed so that the intensity of the magnetic field is greatest at the deepest part A of a molding space 30. As a result, the permanent magnet powder 32 filled in the upper part of the space 30 is magnetically attracted into the rectangular parallelopiped-shaped space 30. Moreover, the powder 32 remaining on magnetic dies 20a and 20b is also perfectly filled into the space 30 in a short time in response to the a.c. magnetic field. Next, a d.c. current is caused to flow through the coil 28 to apply a magnetic field, and the predetermined pressure is applied in order to perform molding in the magnetic field, thereby the compact of an anisotropic magnet is produced. Accordingly, the permanent magnet powder can be filled rapidly in the space even if the opening area of the metallic mold is small or the opening width thereof is narrow, therefore a magnet can be effectively produced.

Filed: 1984-12-24
Abstract: PURPOSE:To obtain a stationary induction electric apparatus which possesses a winding core with excellent magnetic property and also is lowered coil loss by a method wherein a winding core, which is wound continuously by amorphous magnetic alloy belt, is housed in an inside section of an insulated case whose form is annular cylindrical, and a Litz wire, which is a stranded wire of an insulated fine, is used as the primary and the secondary coil. CONSTITUTION:An insulated case 3 is constituted by means that four annular case members 3a, 3b, 3c, 3d, which are formed by synthetic resin, are combined dealing with each side face of wound core 1 and each case member 3a-3d are adhered with adhesive and are sealed. A Litz wire 6, which forms the primary coil 7 and the secondary coil 9, is formed being stranded wire of plural insulated fine and varnished impregnate treatment is performed to a transformer, thus binding property and dielectric strength are improved. Since the wound core 1 made of amorphous magnetic alloy belt 2 is housed in the inside section of the insulated case 3 and is protected, the wound core 1 is not pressed directly by external force. Additionally, as the Litz wire is used to the conductor of the primary and the secondary coil 7, 9, eddy current loss generated to the conductor can be lowered.

IPC: H04L12/40
Filed: 1990-10-12
Abstract: PURPOSE:To simplify the transmitting procedure of serial bus data so as to simplify the transmitting efficiency by making a transmitting station to send transmitting data by coupling the data with a transfer request when the transmitting station has the transmitting data and the receiving station to make updating checks by predicting that sending requests are sent at regular intervals. CONSTITUTION:A main station 11 monitors transmitting time and, when transmitting time comes, checks the presence/absence of transmitting data from the main station to an object slave station. When the transmitting data exist, the station 11 transmits the data together with a transmission request. When no transmitting data exist, the station 11 transmits the transmission request and waits for the arrival of data from the object slave station. On the other hand, slave stations 121-1216 monitor the reception of data for fixed time. When the transmission requesting data arrive from the station 11 during the set time of a timer, the stations 121-1216 discriminate the presence/absence of data to be transmitted to the station 11. The stations 121-1216 transmit data to the station 11 when the data to be transmitted exist and completion of reception to the main station when no data exist. Thereafter the stations 121-1216 set timers and process the received data.
