Title: Receiver for light communication
Inventor: MORI MASAKAZU
IPC: H04B10/07
Filed: 1980-04-30
Abstract: PURPOSE:To prevent the oscillating operation when the input light level is reduced, by changing the loop gain of the full AGC feedback circuit to the avalanche photodiode in accordance with the input light level. CONSTITUTION:The feedback line in operational amplifier OP of the feedback circuit including full AGC to the avalanche photodiode and electric AGC to the gain variable amplifier consists of the parallel circuit of resistance R2, capacitor C, resistance R3, and diode D. The gain of amplifier OP becomes -R2/R1 for the electric AGC operation; and for the full AGC operation, diode D becomes conductive, and capacitor C and resistance R3 are inserted into the feedback line of amplifier OP in parallel with resistance R2, and therefore, the gain of the amplifier is not increased when input voltage ei becomes small. Since capacitor C is used for phase compensation, a margin is given to the phase operation of the oscillating operation. If the voltage control nonlinear element where the resistance value is reduced when voltage ei is increased is used as resistance R3, the gain of the AGC control system is not increased to prevent oscillation even if the input light is broken.

Title: Rotary electric machine having rotor with permanent magnet
Inventor: MOMOZU TOSHIRO
IPC: H02K21/22
Filed: 1990-03-08
Abstract: PURPOSE:To reduce vibration and improve torque characteristics of an electric rotating machine by forming the number of poles of a rotor to an even number differing by one from the number of grooves of a stator core for inserting coils, winding coils of each phase by being alternately reversed, on continuing teeth and connecting them in series. CONSTITUTION:An even numbered (8) magnetic poles differing by one from the number (9) of grooves 3a of a stator core 3 for inserting coils, are magnetized and formed without skewing a permanent magnet 2. A three-phase coil 4 is inserted into a groove 3a, and the coil 4 for each phase is wound by being alternately reversed, on continuing teeth of teeth 3b located between adjacent grooves 3a and formed by connecting them in series. Since the number of magnetic poles is made different by one from the number of grooves of the core, pulsation of torque and vibration during operation can be prevented from being generated and, since no skew is required, the torque characteristics can be improved.

Title: Phase change optical disk and method for reproducing the same
Inventor: OKUBO SHUICHI
IPC: G11B7/24
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a phase change optical disk capable of stably reproducing recorded information without erasing in a phase change optical disk using blue (400-450 nm wavelength) laser light. SOLUTION: A 1st dielectric layer 2, a 2nd dielectric layer 3, a 3rd dielectric layer 4, a recording layer 5, a 4th dielectric layer 6 and a reflecting layer 7 are successively laminated on a substrate 1 to obtain the objective phase change optical disk. When the recording layer 5 is in an amorphous state, the absorption factor of the recording layer is <=70%. When the recording layer 5 is in a crystalline state, the reflectance of the recording layer 5 is 3-15%. Reproduction power is 0.5-0.9 mW. Since the absorption factor of the recording layer 5 is low, the rise of temperature by irradiation with blue laser light having high energy density as laser light for reproduction is suppressed, the crystallization of an amorphous part in the recording layer 5 is prevented and recorded information can be stably reproduced without erasing.

Title: Printing hammer
Inventor: OOTA TAKASHI
IPC: B41J2/295
Filed: 1985-03-20
Abstract: PURPOSE:To attain to enhance a printing speed by effectively and rapidly suppressing rebound, by attracting the flight hammer driven by a piezoelectric element by a permanent magnet. CONSTITUTION:In a printing hammer for a dot impact type printer, when a flight hammer 13 is contacted with the force transmitting member 15 connected to the leading end of a piezoelectric element 11, the magnetic flux generated from a permanent magnet 18 passes through a first yoke 16, the flight hammer 13 and a second yoke 17 to be returned to the permanent magnet 18 as shown by an arrow B. Therefore, attraction force acts on the flight hammer 13. Because the flight hammer 13 flies out forwardly during printing operation, the magnetic flux generated from the permanent magnet 18 reaches the second yoke 17 through the first yoke 16 and does not pass through the flight hammer 13 and, therefore, almost no attraction force 13 acts on the flight hammer 13. Because large attraction force acts only when the flight hammer 13 is contacted with the force transmitting member 15 as mentioned above, rebound can be rapidly suppressed without almost exerting adverse effect on printing operation.

Abstract: PURPOSE:To form a casting mold having good hardness and dimensional accuracy under low squeezing pressure by oscillating a matching plate in the direction intersecting orthogonally with a squeezing direction in the stage of squeezing in a flaskless molding method. CONSTITUTION:Molding sand is packed in a matching plate 1, a squeezing head 3 and a flask 3, and the plate 1 is oscillated transversely at about 30-100Hz frequency and about 0.2-1mm. amplitude by means of a vibrator 4. About 3- 10kg/cm<2> squeezing pressure is applied at the same instant on the sand by the head 2 in the direction perpendicular to the above-mentioned oscillating direction to reproduce exactly the ruggedness of the matching plate, thereby eliminating the uneven sand hardness in the casting mold. The casting mold which has satisfctory hardness and dimensional accuracy without shape collapsion is thus formed under the low squeezing pressure.

Abstract: PURPOSE:To stably silence the air suction noise changing with the rotating speeds of an engine and an environmental change by changing the volume of the resonance space of a resonator by the information in the rotating speed of the engine and finely adjusting the change in the volume of the resonance space by the information on the fluid pulsation of the fluid flowing in an intake duct. CONSTITUTION:The fluid pulsation arises in the intake duct 4 at the time of sucking the air for combustion and this pulsation causes the air suction noise. The air suction noise, therefore, changes largely according to the rotating speed of the engine. The rotating speed is, thereupon, obtd. from a device 3 for detecting the rotating speed of the engine by a control unit 5 and the volume 16 of the resonance space is controlled by a volume controller 6. The frequency of this noise is changed by the change of the environment such as the temp., humidity,. The fluid pulsation in the intake duct 4 is, thereupon, detected by an air flow sensor 2 and the volume 16 of the resonance space is finely adjusted with the control unit 5, by which the resonance frequency is corrected.
