Title: Magnetic disc device
Inventor: KATOU MASAHIRO
IPC: G11B33/12
Filed: 1982-10-18
Abstract: PURPOSE:To protect normal recording and reproduction and to improve the reliability of device, by adopting the constitution that a member shutting a disc insertion slot is provided in interlocking with an automatic loading mechanism of a disc. CONSTITUTION:When a position detecting means detects that the disc 4 reaches normal clamping position, the drive of carrying motor is stopped and the carriage of the disc 4 is stopped. Then, a solenoid 5 is excited and attracts the drive shaft. Thus, a support arm 13 is tensed and turns against an energizing force of a tensile spring 14 counterclockwise as shown in an arrow (b). A cone 16 falls down and is fitted to a spindle 8 through a center hole of the disc 4. The disc 4 is clamped by being clipped with the cone 16 and the spindle 8 via a center hole from up and down sides. A shutter 17 falls down attended with the turning of the support arm 13 toward (d) and the disc insertion slot 3 is shut. Then, the display message of the shutter 17 of ''Disc is loaded'' appears at the opening of the disc insertion slot 13.

Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To improve insulation between the rotor and stator of the rotary transformer of an ultrasonic probe by interposing an insulating film between the rotor and stator of the rotary transformer. SOLUTION: Concerning a stator 8 of a rotary transformer 7, an insulating film 16 having thickness about from several μm to several tens μm is stuck on the surface confronted to its rotor 9. Concerning the quality of this insulating film 16, any material, with which a certain degree of strength can be secured and the smoothness of the surface is improved even when it is thin, is used. For example, polyimide or Teflon is suitable. Coils 8-1 and 9-1 are floated from respective grooves and mutually touched by this insulating film 16 and that insulating film is prevented from being destroyed. Besides, corresponding to the thickness of the insulating film 16, the gap between the rotor 9 and the stator 8 is kept constant and the setting of the gap at the assembly time of the rotary transformer 7 and following gap holding are facilitated.

Printing is executed with an electrostatic printer-plotter by using the electrostatic recording body obtd. in such a manner, by which the good recording image is obtd. without the line disconnection and abnormal discharge. The effect is highly admitted when the recording body is used for the CAD in particular.

Title: Screw propeller
Inventor: NOBUNAGA HIROSHI
IPC: B63H3/00
Filed: 1985-08-21
Abstract: PURPOSE:To improve propelling efficiency, by a method wherein a propeller itself has structure in that the pitch of a blade is variable during one full rotation of the propeller, and the pitch is made suitable to wake distribution. CONSTITUTION:The pitch of a blade 5 is decreased in a region in which the coefficient of wake is high during one full rotation of a propeller, and the pitch of the blade 5 is increased in a region in which the coefficient of wake is low, and this causes generation of uniform thrust during one full rotation of the propeller. In which case, distances L1-L4 between a contact surface or a tooth surface 14 forming a rail and a swirl center C of the blade 5 are set at each ship depending upon wake distribution. Peripheral rounding on the contact surface or the tooth surface 14 of a taper roller or a bevel gear 13 togetherwith a boss rotated by a propeller shaft 3 causes reciporating movement of a lever 12, and the pitch of the blade 5 is varied so as to be suited to the wake distribution. This improves propelling efficiency, and also reduces production of vibration due to wake.

Title: Presence/absence discrimination system for liser of communication terminal
Inventor: TAKEUCHI KOICHI
IPC: G01S7/52
Filed: 1986-08-04
Abstract: PURPOSE:To discriminate whether a terminal user is present or not automatically by recognizing that the user is nearby a terminal automatically when the intensity of a signal wave transmitted by a small-sized transmitter receiver held on the body of the user is larger than a constant value. CONSTITUTION:Transmitting circuits 1e-Ne transmit signal wave pulses obtained by modulating a carrier in different time phase by small-sized radio transmitter receivers 2a and Na within a constant time period. Receiving circuits 1d-Nd receive calibrated wave pulses transmitted to the receives 2a and Na from a user identification communication terminal so as to hole the time phases of the transmitter receives 2a and Na independent. The circuits 1d-Nd detect signal wave pulses from the transmitter receivers 2a and Na and impose modulation. A specific circuit 1g controls the time phase difference corresponding to the transmitter receivers 2a and Na to specify persons who hold the transmitter receivers 2a and Na. The circuits 1e-Ne transmit modulated calibrated pulses to the transmitter receivers 2a and Na. An intensity decision circuit 1m decides whether the intensity values of the signal waves from the transmitter receivers 2a and Na exceed a certain reference level or not.

Title: Semiconductor laser device
Inventor: KUME MASAHIRO
IPC: H01S5/00
Filed: 1985-08-20
Abstract: PURPOSE:To reduce the hopping noise of a laser light induced by returning light by a method wherein Sn in employed as an impurity in an N-type GaAlAs cladding layer which composes a double-hetero junctions. CONSTITUTION:An N-type GaAs layer 2 on a P-type GaAs substrate 1 concentrates injected current in a V-groove 9 to facilitate continuous oscillation of low threshold and the laser oscillation is induced in an activation layer 4 on the V-groove 9. Mg of the concentration of less than 3X10<18>/cm<3> is added to a P-type cladding layer 3 and Sn of the concentration of 5X10<17>/cm<3> is added to an N-type cladding layer 5. Effective refractive index distribution is provided in the junction by the V-groove 9 to stabilize horizontal modes. Generally speak ing, a laser which oscillates a vertical single mode bem when returning light does not exist oscillates a multimode beam when the returning light exists. If singularity is excessively precise, it does not oscillate a perfect multimode beam and creates very large noise caused by mode hopping at the time of transfer from single mode to multimode. If Sn is employed, the vertical mode can be converted into the multimode satisfactorily in a practical returning light range so that the low noise level can be realized.

IPC: G03G15/16
Filed: 1991-07-23
Abstract: PURPOSE:To shorten a movement stroke in the width direction of a plain belt in a belt drive device capable of automatically detecting and correcting partial movement. CONSTITUTION:A transcription belt 4 is travelably mounted over three first - third rollers 1-3. A partial movement detection member 11 is arranged at the shaft end part of the third roller 3, and initial partial movement is eliminated by generating a reverse direction partial movement component in the transcription belt 4 through a process of displacing the shaft end part of the third roller 3 with a string member 13 wound by the rotation torque of the partial movement detection member 11, caused by the partial movement and the resultant contact with the partial movement detection member 11 of the transcription belt 4. A spring 17, giving energization force in a reverse direction to a winding direction to the string member 13, and a damper 18 acting winding resistance are linked in parallel to prevent the sudden rotation of the partial movement detection member 11, reducing a movement stroke in the width direction of the transcription belt 4.
