Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a tire, and enhance the performance on ice, in the pneumatic tire in which circumferential sipes are formed in the block. SOLUTION: The water film between a tire and an ice surface is efficiently discharged by forming a plurality of circumferential sipes 48 in a block 34 for enhancing the performance on ice. Denoting by s and d respectively the length of the side 48 in the circumferential direction of a tire and the distance between the circumferential sipes 48, the following relationship is to be satisfied: 0.5<=s/d<=2.5. Thus, the rigidity of the slender region 49 between the circumferential sipes 48 can be sufficiently secured, and the occurrence of crack from the end of the sipe can be restrained by preventing the breakage of the block.

Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To replace a worn electrode and to suppress the noise quantity generated from a lamp itself by moving at least one of electrodes inside a discharge lamp sealing rare gas and adjusting the interval between the electrodes. SOLUTION: A negative electrode 1 in a lamp is vertically moved in an arrow direction so that a point shielding a detection beam 22 between a projector 21 and an optical receiver by an optical shielding plate on the negative electrode is measured. This measurement sets the interval between electrodes and measures the abrasion extent of the electrodes.

Title: Rotor with embedded magnet
Inventor: HARA TAKATOSHI
IPC: H02K1/27
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To considerably reduce vibration and noise from a motor by giving magnetic axis direction anisotropy in magnetic orientation of a magnet, thereby reducing pulsation in main magnetic flux torque component and reluctance torque component. SOLUTION: Magnetic orientation of a magnet 2a is formed to anisotropy in magnetic pole axis direction parallel to the magnetic pole center axis z of each pole. By doing this, at the end of the magnet 2a of each pole, magnetic flux by the magnet 2a flows out from or flows to the magnet 2a along the direction 5a of the magnetic orientation. As a result, the amount of the magnetic flux in air gap per rotation of the rotor becomes more regular, the pulsation in main magnetic flux torque component and the pulsation in reluctance torque component can be reduced and the vibration and noise of the motor can be significantly decreased.

Title: Check valve
Inventor: IMAKITA MICHIHIKO
IPC: F16K17/10
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To prevent generation of chattering. SOLUTION: A vertical penetrating hole 45 is disposed on an axial center of a poppet 33, and horizontal holes 46 crossed with the vertical penetrating hole 45 are disposed. A spool 47 is slidably fitted to the vertical penetrating hole 45, and is energized toward a position for closing the space between the vertical penetrating hole 45 and the horizontal hole 46 by a second spring 48. Since a displacement for opening is comparatively large by the spool 47 and the diameter of the spool 47 is smaller than that of the poppet 33, pressure is controlled in a condition in which the displacement is large, and thereby, generation of chattering phenomenon is prevented. A passage 50 for braking and pressure balance is disposed on the poppet 33.

Title: Optical information recording and reproducing method and optical information recording medium
Inventor: NARUMI KENJI
IPC: G11B7/125
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording and reproducing method capable of making the control levels of light intensity at the time of recording and at the time erasure the same and easily obtaining stable light. SOLUTION: Recorded data signals generated in a recorded signal modulator 103 are high frequency-modulated in a high frequency modulator 115 and a current for driving a laser 105 is modulated based on the high frequency- modulated data signals thus obtained. In a laser modulator 104, peak intensity at the time of recording and at the time of erasure is fixed and a duty is changed. Thus, the control levels of the light intensity at the time of recording information and at the time of erasing the information are made the same. As a result, stable light is easily obtained. Especially, since the light obtained by converting a part of laser beams to higher harmonics is used as light for irradiating this optical information recording medium, the duty of an emitted light waveform is easily controlled and the information is more easily recorded and erased.

Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To measure intra-station delay, delay fluctuations and frequency characteristics in an actual operation state over a wide band by performing the correlation processing of signals for phase calibration signal detection and phase calibration signals and obtaining a phase spectrum after Fourier transformation. SOLUTION: Reception signals are received by an antenna 1, and delay calibration signals 2 are injected to the reception signals by a directional coupler 3. Then, they are converted by an amplifier 4, a frequency conversion part 5 and a filter 6, etc., and the signals and the phase calibration signals are recorded at the same time (measured). For the detection of the phase calibration signals, the ones for which spread signals at a frequency at the time of data recording are prepared (calculated or actually generated), based on a spreading code (base band signal) and gathered data are correlated. For the frequency characteristic over the entire band, by obtaining a frequency spectrum by a mutual correlation result and calculating the ratio of a real component and an imaginary component, the phase spectrum 11 is obtained.  Also, the phase calibration signals are subtracted from a signal phase and delay received inside a station like a receiver, a frequency converter/amplifier and a filter, etc., or the like is removed.

Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To detect an appropriate finish point of etching. SOLUTION: In a part of a sample, an oscillator 71 consisting of a beam 72 twice as wide as a desired quantity of etching and a mask 74 provided with a plurality of etching holes 76 disposed at narrower intervals than the width of the beam 72 is formed from an unetched structure formation layer 84 which is formed on the surface of a sacrifice layer 82 to be etched. Etching is execute while the sample is oscillated at the characteristic frequency of the oscillator 71. Until the etching proceeds to the desired quantity, the beam 72 of the oscillator 71 is fixed to the sacrifice layer 82 and therefore does not oscillate with respect to the sample. When the etching reaches the desired quantity, the sacrifice layer 82 under the oscillator 71 is removed by etching and therefore the oscillator 71 starts oscillating with respect to the sample.  The displacement of the oscillating state of the oscillator 71 is detected by laser light from a displacement gauge as a quantity of displacement of the oscillator 71 to detect the finish of the etching.
