Patent JP-H01153166-A (JP)
Title: Laser probe
Inventor: OSHIMA YUTAKA
IPC: H01S3/101
Filed: 1987-12-11
Abstract: PURPOSE:To enable even irradiation with laser and to provide stabled irradiation condition by making a condensing lens changeable of the focusing point by moving it before and behind to a light introducing tip for discharge with retractable operations. CONSTITUTION:The light introducing tip 6 is constituted so that laser beam enters from the bottom 8 and emits from a circular cone 9. The laser beam introduced by laser guide 4 enters into the light introducing tip 6, and most of it is reflected totally on the inner surface of the circular cone 9, followed by further reflection on the inner surface of the circular cone 9. By repeating such reflections, laser beam reaches the top with gradual converge. When the incident angle against the inner surface of the circular cone 9 exceeds the total reflexion angle, laser beam is released in a ring form from the circular cone 9. Before the laser beam reaches the top-most part of the light introducing tip 6, it is released from the part of the circular cone 9. Thus, laser is directed onto a ring form area e with little release towards anterior sine of the central axis. Thus, laser can be directed efficiently and evenly even to the peripheral area which require irradiation, avoiding irradiation of unnecessary sites.

Abstract: PROBLEM TO BE SOLVED: To provide a first order approximation circuit for estimating propagation path characteristics that is weighted with regard to a time difference among measurement points and to provide a propagation path characteristics estimation circuit where the memory capacity required for the estimation or the arithmetic operation load is reduced. SOLUTION: An accumulator 11 accumulates the detection signal of a pilot signal in each unit time (slot). An accumulator 12 accumulates a value that is the product of the detection signal of the pilot signal and the signal position (n) in the slot for each slot. An adder 19 sums up the output of the accumulator 11 that is multiplied by a coefficient (4N-2)/(N(N+1)) and the output of the accumulator 12 that is multiplied by a coefficient -6/(N(N+1)). An adder 20 sums up the output of the accumulator 11 that is multiplied by a coefficient -6/(N(N+1)) and the output of the accumulator 12 that is multiplied by a coefficient 12/(N(N-1)(N+1)). A value resulting from applying low pass filter processing to the output of the adder 20 represents the gradient b(k) of the propagation path characteristics of the slot.  The output of the adder 19 corrected in response to the gradient b(k) represents the bias a(k) of the propagation path characteristics of the slot.

IPC: H04L9/06
Filed: 1989-12-01
Abstract: PURPOSE:To prevent a bit error from giving effect onto an entire block by exclusively ORing an information data with a cryptographic key, sending the result, applying S/P conversion, exclusively ORing the result with a decoding key and decoding the ORed data. CONSTITUTION:A transmission side latches an input information data S1 as a block in the unit of N bits and sends the data to an exclusive OR circuit 11. The circuit 11 applies exclusive OR calculation between the data and a cryptographic key SA from a cryptographic key generating circuit 13 to output a cryptographic data S2. A P/S conversion circuit 12 applies P/S conversion to the cryptographic data S2 and sends the result to a reception side. An SP conversion circuit 22 at the reception side applies S/P conversion to the cryptographic data, reproduces the data S2 and sends the data to an exclusive OR circuit 21. The circuit 21 applies exclusive OR calculation between the data S2 and a decoding key SB generated by a decoding key generating circuit 23 to decode the data and outputs an output information data S3. Thus, even when the received cryptographic data has a bit error, the error is limited to the bit only and not affected to the entire block.

IPC: G01J3/45
Filed: 1986-12-30
Abstract: PURPOSE:To enhance measuring accuracy by performing measurement in the optimum state by correcting the whole of an interferometer, by a method wherein test luminous fluxes are allowed to be incident to the interferometer to be allowed to interferometer to be allowed to interfere with each other and the state of interference is received to control an optical element. CONSTITUTION:The reflected luminous flux P1 from a fixed mirror Mf and the reflected luminous flux P2 from a moving mirror Mv are projected on a four-split light detector Df and interfere with each other on the light receiving surface of the detector Df. As a result, the outputs of elements Df1, Df2... perform the variation of one cycle during a time when the moving moving mirror Mv moves by 1/2 a light wavelength. When the luminous fluxes P1, P2 are superposed in a state slightly shifted each other, the luminous intensity distributions of the cross-sections of the luminous fluxes lower toward the outer peripheries thereof and, therefore, the variation amplitudes of the outputs of two elements do not coincide with each other. When the posture of Mf or Mv is controlled so that the amplitude becomes max. in one light receiving element and the amplitude becomes min. in the other element at a diagonal position, the luminous fluxes P1, P2 perfectly coincide on the detector Df and optical axes coincide with each other to perfectly adjust the optical elements and measurement can be carried out in the optimum state.

Filed: 1990-11-19
Abstract: PURPOSE:To obtain rotating power by employing permanent magnet stator and rotor and interacting an interacting piece while altering the polarity appropriately thereby utilizing the magnetic force of the permanent magnets to the maximum. CONSTITUTION:A stator D comprises six permanent magnets, i.e., twelve poles, whereas a rotor comprises three permanent magnets, i.e., six poles, wherein an interacting piece is disposed between the stator D and the rotor E with the circumference thereof being divided equally into six sections constituting interacting parts and space parts alternately. Body of the interacting piece is made of nonferrous metal while the interacting part is made of iron and embedded with an electromagnet with the polarity thereof being alterable appropriately through a polarity altering unit. Furthermore, an interacting piece reversal unit reverses the rotational direction of the interacting piece with respect to a shaft A. When a rotor S pole 7 repels a stator S pole 5 and rotates to the right, pole 6 of the interacting piece is altered to S pole whereas the pole 2 of the interacting piece is altered to N pole. Consequently, the pole 6 of the interacting piece repels the stator S pole 5 and the rotor S pole 7 whereas the pole 2 of the interacting piece repels the rotor N pole 3 and thereby the interacting piece begins to rotate to the left. This function is linked to rotate the rotor E to the right.
