Title: Rotary magnetic sheet device
Inventor: NISHIKAWA KAZUHIRO
IPC: G11B5/024
Filed: 1985-06-19
Abstract: PURPOSE:To erase completely an optional track after recording by a recording/ reproducing head in a short time by applying an alternate current whose direction is inverted at each rotation of a magnetic sheet to a magnetic head and moving the magnetic head at each 2-rotation of the magnetic sheet by a prescribed quantity alternately in the broadwise direction of the track to be erased. CONSTITUTION:Every time each point on the magnetic sheet passing on the magnetic head passes on a gap of the magnetic head, magnetization with inverted polarity is applied and erasure is executed. Since the magnetic head is moved alternately by a prescribed quantity (minute quantity equivalent to eccentricity) in this case at each 2-revolution of the magnetic sheet, ends of a recorded track are subjected to a forward/backward magnetization during two rotations when the magnetic head passes and subjected to no magnetization during the next 2-rotation because the magnetic head is parted. The operations above are repeated. Thus, an optional recorded track is erased completely by a recording or a recording/reproducing head in a short time regardless of the eccentricity of the magnetic sheet.

Title: Alminum-stabilized superconducting wire
Inventor: WADA KATSUNORI
IPC: H01B12/10
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a superconducting wire which is superior in thermal and electrical stability and has a sufficient mechanical strength against electromagnetic force generated, when used as magnet. SOLUTION: This superconducting wire 33 is formed, such that the outer circumference of a superconducting wire material 31 in whose copper matrix a superconducting filament is embedded is coated with an Al-stabilized material 32. In this case, 0.2% proof stress of the Al-stabilized material 32 at a very low temperature is set to 70 MPa or more and its residual resistance ratio to 250 or more. Further, the Al-stabilized material 32 is adapted to contain Ce of 0.3 to 3.0 weight % and to comprise an Al alloy cold which is cold worked at a rate of 5 to 30% of reduction in area or which has working distortion added thereto, equating to this working.  This causes the Al-stabilized material 32 to contain an appropriate quantity of Ce, which enhances mechanical strength without lowering the conductivity, to have prescribed working distortion added thereto, and to have 0.25 proof stress and a residual resistance ratio which are established more than prescribed values. Thus, when used as conductor for use in a magnet and the like, deformations caused by electromagnetic force is small and generation of high magnetic field is obtained.

Title: Switching regulator corresponding to low output
Inventor: MORIWAKI YUICHI
IPC: H04N5/63
Filed: 1990-05-23
Abstract: PURPOSE:To suppress the power loss and heating in a switching regulator by continuously performing oscillation for switching of the switching regulator in the normal mode and interruptedly performing oscillation in the stand-by mode. CONSTITUTION:When a television receiver is operated in the normal mode, a transistor TR Tr4 is in the turning-on state and the light emitting diode of a photocoupler PH1 emits light. By this light emission, a TR Tr1 is switched with a frequency corresponding to the load. When the operation mode of the television receiver is switched to the stand-by mode, the TR Tr4 goes to the turning-off state and the light emitting diode of the photocoupler PH1 does not emit light. Then, the TR Tr1 is switched based on a driving current iD. Therefore, the power loss and heating of the switching regulator are increased by the rise of the switching frequency only in a period T2.

Title: Drive controller for injection molding machine
Inventor: MURAMATSU MASAHARU
IPC: H02P23/00
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To achieve mold clamping at sufficiently high torque with a low capacitance by providing one-phase coil of a permanent-magnet type motor separated into a plurality of coils, and by detecting the positions of the mold clamping and mold releasing so as to be switched to a parallel-connection and a series-connection. SOLUTION: An injection molding machine connects two coils U1 , U2 in a U-phase of a motor coil 1 at the connecting terminals U11 , U12 , U21 , U22 in series or in parallel. The switching from the parallel-Y connection to the series-Y connection of the motor coil 1 is exerted by detecting the positions directly before the mold clamping in the mold clamping process, and by turning the (a) contact point 2 of the switch ON and turning the (b) contact point 3 OFF, so as to be switched from the parallel- to the series-connections.  On the other hand, the switching from the series-Y connection to the parallel-Y connection is exerted by detecting the retreated position from the switching position of the mold clamping process in the mold releasing process, and by turning the (b) contact point 3 of the motor coil ON and turning the (a) contact point 2 OFF, so as to be switched from the series- to para-connections. This permits each region of a high-speed low-torque and a low-speed high-torque to be used appropriately.

Filed: 1983-07-22
Abstract: PURPOSE:To evaluate non-destructively undoped GaAs crystal by using a semiconductor laser or light emitting diode as a light source for excitation and detecting the transmitted light of the laser luminous flux from a solid-state laser using an Nd:YAG crystal as a source for oscillation. CONSTITUTION:The absorption intensity of an undoped GaAs crystal is weak on the outside of an absorption end and the absorption occuring in a ''deep level'' forms a wide peak at 1.0-1.1mu wavelength. Since it is difficult to obtain a semiconductor laser having an oscillation wavelength in this wavelength region, a solid-state laser consisting of Nd:YAG to be excited by a semiconductor laser is used. The light 2 oscillated from a semiconductor laser 1 is condensed to an Nd: YAG crystal 4 and when conditions for excitation satisfy the conditions for oscillation, light 5 excited at 1.06mu is obtd. Such light 5 is condensed to a GaAs substrate crystal 7 to be examined and the light 8 transmitted through said crystal is detected by a detector 9, by which the crystal is evaluated.
