Patent JP-S58182283-A (JP)
Title: Light emitting diode
Inventor: OOSHIMA SHIGERU
IPC: H05B44/00
Filed: 1982-04-19
Abstract: PURPOSE:To obtain the light emission of the same brightness as in case of using for a DC power supply, even when used for an AC power supply, by connecting light emitting elements of the same number which are reverse each other in polarity in parallel on the same semiconductor chip. CONSTITUTION:The light emitting elements 1 and 2 are reverse each other in polarity and connected in parallel. A resistor 3 which controls the current flowing through the light emitting elements 1 and 2 is connected in series with the both light emitting elements. These light emitting elements and the resistor are formed on the same semiconductor chip. In a light emitting diode constituted of such a circuit, when a positive voltage is impressed between terminals 10 and 11, the light emitting element 1 emits light, and, when a negative voltage is impressed, the light emitting element 2 emits light. Therefore, if the absolute values of applied voltages are the same, they emit light continuously at the same brightness as a light emitting diode even if the polarities are different. That is, they emit light continuously at the same brightness even when used for an AC power supply. Thus, even when used for an AC power supply, the light emission of the same brightness as in case for a DC power supply can be obtained.

Title: Magnetic recording and reproducing device
Inventor: SHIMODA KENJI
IPC: H04N5/783
Filed: 1985-03-29
Abstract: PURPOSE:To suppress the generation of a reproduced horizontal frequency by adopting the constitution that a level change in a selected output is executed gradually in selecting alternatively plural signals for motor drive control in response to the changeover of the reproducing mode. CONSTITUTION:A switch 34 selects an output of an APC system circuit 32 in the normal reproduction mode and selects an output of a bias voltage generating circuit 33 in the special reproduction mode such as the cue/review mode. The selected output is given to a time constant circuit 35 and the level change in the selected output is slow and the change in the drive speed of a motor 37 changes slowly. Since the motor speed does not change quickly, the fluctuation of the reproduced horizontal frequency due to the change in the drive speed of a cylinder motor is suppressed sufficiently by the change in the drive speed of a capstan motor and generation of flowing of the reproduced horizontal frequency is minimized.
Patent JP-S55158778-A (JP)
Title: Picture signal producing device
Inventor: SATOU YOUJIROU
IPC: H04N1/403
Filed: 1979-05-26
Abstract: PURPOSE:To always obtain the proper binary coded signal, by varying the threshold voltage based on the time interval of the shift amount detection pulse of the secondary scanning direction. CONSTITUTION:Time interval Tp of shift amount detection pulse Pd which is produced successively at shift amount detector DS varies according to the fluctuation of the secondary scanning speed. The frequency/voltage converter produces the DC voltage featuring the level corresponding to the repetitive frequency of pulse Pd, and then inverts the polarity through inverter INV. Thus threshold voltage Vs is produced for the binary coding of the picture signal. Voltage Vs is then applied to comparator COMP in the form of reference voltage Vs. On the other hand, driving circuit DC is controlled by pulse Pd, and image sensor IS is made to start the main scanning with every producing time position of pulse Pd. Thus signal Sa is produced in correspondence with the picture information to be applied to reading amplifier A. Amplifier A supplies the picture signal to comparator COMP in the form of the comparison signal. Comparator COMP carries out the binary coding of signal Sa via voltage Vs which fluctuates according to the fluctuation of the input signal level. As a result, good output binary coded signal can always be obtained.

Title: Sort processor
Inventor: SATO TETSUJI
IPC: G06F7/24
Filed: 1987-03-19
Abstract: PURPOSE:To sort a large quantity of input records in order in which a similarity with a reference value is high by providing a means to calculate an absolute value of the difference between the reference value and the key part of the input record at the input part of a sort processing circuit. CONSTITUTION:Since an input record, while ¦A-X¦ is calculated by an arithmetic circuit 11 for a key part X only, is inputted to a sort processing circuit 15, for example, a head record 3-1 is converted from a reference value A=5 to 2-1 and inputted into the sort processing circuit 15. Through the arithmetic circuit 11, a record converted to the key part X only is sorted in an ascending order way including the ID part. Consequently, at records (3-6 and 3-7) in which the key part X equal, it is judged that the record (3-6) having a smaller ID part is smaller. It is decided from the arrangement of the record to execute the ascending order sort that the record having a key closest to the reference value A=5 is a record in which ID is 2. Hereinafter, the record is outputted from the sort processing circuit 15 in the order close to the reference value with the difference in a reference value A as a key part and an (n) number of records high in similarity is extracted.

IPC: H04L27/22
Filed: 1992-03-24
Abstract: PURPOSE:To absorb a drift and Doppler frequency fluctuation in a long period. CONSTITUTION:A frequency converter 1 converts a PSK modulation carrier signal Si passing an input band-pass filter 11 and an output signal S5 from a voltage controlled oscillator(VCO) 4 to an IF signal S1 by mixing. A demodulator 2 demodulates the IF signal S1, and outputs a demodulation signal So and a frequency error signal S2. A low-pass filter 3 eliminates an unrequired component included in the error frequency signal S2, and outputs a control signal S3 to absorb the drift in a long period. A multiplier 6 and a band-pass filter 7 multiply the IF signal S1, and the unrequired component is eliminated, and a carrier component S6 is extracted. A phase comparator 8 outputs a phase difference signal S7 by comparing the carrier component S6 with an output signal S9 from a VCO 10. A low-pass filter 9 eliminates the unrequired component, and outputs a control signal S8 to absorb the Doppler frequency fluctuation. An adder 5 supplies a control signal S5 on which the control signals S3 and S8 are superimposed to the VCO 4.

Title: Cylinder device for sheet-fed rotary press printer
Inventor: KOMORI TAKEO
IPC: B41F22/00
Filed: 1983-04-14
Abstract: PURPOSE:To raise the quality of printed materials by setting up the phase of a plate cylinder and a rubber cylinder in such a way that the clamping angle of the printing plate is faced the notch-starting point of the periphery of the cylinder on the downstream side of the rotation slightly from the clamping angle of a blanket. CONSTITUTION:The circumferential phase of a plate cylinder 19 and a rubber cylinder 20 is set up in such a way that the clamping angle of a printing plate 21 is faced the notch-starting point of the periphery of the cylinder on the downstream side of the rotation slightly from the clamping angle of a blanket 51. In this case, the face of the claw-opening and closing cam 57 is formed in such a way that the paper clamping claw 54 of the rubber cylinder 20 is opened. Even when ink is adhered to the clamping angle of the plate cylinder 21 due to the contact between the clamping angle and a roller, since the ink does not move to the blanket 51 of the rubber cylinder 20, no staining of paper occurs, and therefore, the quality of printed material can be raised and the loss of paper can be reduced. Also, since the phase of the printing cylinder can be advanced toward the turning direction rather than the rubber cylinder, the clamping margin can be made smaller and consumption of paper can be saved.

Title: Piezoelectric oxide material
Inventor: YAMASHITA YOUHACHI
IPC: C04B35/46
Filed: 1979-05-30
Abstract: PURPOSE:To obtain a high-performance piezoelectric material by replacing a portion of Pb in PbTiO3-Pb(Me1/2W1/2)O3 (Me is Mg or Ni), and adding a small amount of one of MnO, NiO, and Fe2O3 if required. CONSTITUTION:In (1-x)PbTiO3-xPb(Me1/2W1/2)O3, Mg or Ni is used as Me, and the composition is adjusted to obtain 0.01<x<0.15. In the case x<0.01, the  sintering property is poor. In the case 0.15<x, the curie temperature is decreased  below 350 deg.C. At temperature higher than 300 deg.C, stabilization is achieved, but the  material cannot be used. Permittivity value becomes higher than 300, and the utilization in a high-frequency region cannot be made. Then, if Pb of 0.5-20  atomic % is replaced with Sr, the polarization and sintering of the piezoelectric  material can be readily performed, and the material can be used at the high temperatures. If one of MnO, NiO, and Fe2O3 of 0.05-2wt% is added as an accessory  ingredient, the temperature characteristics, the time duration characteristics, and the mechanical-quality factor of PbTiO3-series ceramic become excellent and the  large sintered bodies can be formed.

IPC: E02F3/28
Filed: 1981-04-30
Abstract: A mechanism for resonantly driving a moveable cutter blade located at the base of a concave tool is disclosed. An angulate beam has first and second legs meeting at a juncture at an included angle of less than 180 DEG . The beam includes a mounting flange which extends inwardly from the juncture between the legs. The beam has a resonant frequency, when restrained at the mounting flange, with a node at the juncture and first and second anti-nodes at the ends. One end of the beam receives a vibratory input or near the resonant frequency so that the second end vibrates about a neutral position. The mounting flange is attached to the tool so that the angulate beam conforms to the concave shape of the tool. The neutral position of the second end of the beam is spaced from the back of the cutter blade within striking distance of the blade. The input vibration at the first end of the beam causes the second end to vibrate about its neutral position and impart forward impulses to the cutter blade to drive the blade intermittently forward.
