Title: Optical recording medium
Inventor: AKAHIRA NOBUO
IPC: G11B7/243
Filed: 1978-09-04
Abstract: PURPOSE:To attain high-density recording in a visual and infrared range by low energy by adding an lower oxide of Tl, Bi or In to a principal component, a lower oxide of Te. CONSTITUTION:Into powder of TeO2, more than one kind of oxides among Tl2O3, BiO3 and InO3 are mixed and dissolved in the air to obtain a mixed solid solution. The powder of this solid solution is fused in a metallic boat, where it is evaporated being reduced, thereby vapor-depositing it on a substrate (synthetic resin sheet, etc.). Consequently, a thin plate is formed which contains (y)mol% (0<Y<30) of more than one of TeOX1 (0<X1<20), TlOX2 (0<X2<1.5), BiOx3 (0<X3<1.5), and InOx4 (0<X4<1.5). In this way, recording is attained by He-Ne laser light of less than 50mJ/cm<3> in energy density. A difference in permeability and that in reflection coefficient during regeneration are increased.

Title: Synchronous type dc motor
Inventor: BAN ITSUKI
IPC: H02K29/00
Filed: 1988-05-06
Abstract: PURPOSE:To remove rotation unevenness and vibration by forming the field distribution curve of a field pole into a sine wave and by applying an armature current proportional to the inductive output of a coil facing the pole. CONSTITUTION:Magnetic poles 5a, 5b,... of a magnet rotor 5 are magnetized so that their field distribution curve becomes a sine wave. Therefore, because the applied current waveform of an armature coil 10a controlled by the inductive output of a first phase armature coil 10a also becomes a sine wave, the output torque becomes the squared curve of the sine wave. The action of a second phase armature coil 10b or a third phase armature coil 10c is also the same as that of the first phase armature coil so that the output torque curve of each coil becomes the squared curve of a sine wave. Further, the torque curves of the first, second, and third phase armature coils 10a, 10b, and 10c are successively delayed in phase by 120 degrees. Therefore, the composite torque curve is flattened and a torque ripple disappears.

Title: Aluminum alloy plate with superior weldability for wheel rim
Inventor: FUKUI KIYOYUKI
IPC: B23K11/18
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To secure welding strength and to prevent generation of weld crack at the time of rim forming by reducing the thickness of a surface oxide layer in a part containing the sides that form the end face of an alloy plate to be welded. SOLUTION: The thickness of an oxide layer 15 is adjusted to be 100 Åor less, desirably 10 Å or above and 100 Å or below, for the forming-required area 16a, 16b of an aluminum alloy plate 10 for wheel rims, the area including the end face 12a, 12b of the plate and having an width of at least about twice the thickness t of the plate from its side 13a, 13b. As a result, in the DC butt welding of the end face 12a, 12b, the oxide is reduced that flows into the weld zone, thereby preventing a weld crack caused by the oxide at the time of subsequent rim forming. The thickness of the oxide layer 15 is adjusted by acid cleaning of the base material in two steps using for example a sulfuric acid solution and a nitric acid solution.  Incidentally the acid cleaning area is the entire surface, which is advantageous costwise in view of a means like masking, rather than the limited area of 16a, 16b for which forming is required.

Title: Correction system for phase shift of magnetic recording information
Inventor: ISHIBASHI MASAYUKI
IPC: G11B20/16
Filed: 1979-08-31
Abstract: PURPOSE: To prevent the generation of the skew by suppressing a phase shift by advancing a read waveform in phase by fixed extent while recording information is inverted in polarity at continuous phase positions.  
     CONSTITUTION: When read information shows "0", FF15 is not set and only AND gate 16 can get open to pass information "1" following information "0" through delay circuit 13, so that the peak appears at the normal position. Once read information "1" appears, FF15 is set and AND gate 16 is opened to make only AND gate 17 ready to open, so that the following information "1" will be sent to read register 14 being advanced in phase without being delayed by delay circuit 13. As a result, the phase shift is corrected and if information "0" follows "1", FF15 is reset for initialization. Thus, the phase shift is suppressed, so that the generation of the skew can be prevented.

Filed: 1977-09-13
Abstract: PURPOSE:To produce a miniature and inexpensive optical fiber branching device by using a triangular double-refractive crystal having its one side formed with a dielectric film and arranging the incidence photometric fiber on said crystal. CONSTITUTION:The incident light 9 having passed through an incidence photometric optical fiber 1 goes through a microlens 10, which is operative to efficiently introduce the light into emanating photometric fibers 6 and 8, into a triangular double-refractive crystal 11 so that it is divided into two rays of normal and abnormal rays 12 and 13, which are introduced into a crystal surface 14. Since this surface 14 is coated with an optically transparent dielectric film 15, the fiber 1 and the microlens 10 are so arranged that the angle of incidence of the normal ray 12 is higher than the crystal value. Then, the normal ray is totally reflected upon the crystal surface 14 so that it propagates through the crystal, while having its optical path curved, until it goes into the other fiber 8. Since, on the contary, the abnormal ray 13 does not satisfy the total reflecting condition at the surface 14, it is allowed to pass through the film 15 so that it goes into the other emanating photometric fiber 6.
