Title: Method for estimating control parameter of robot
Inventor: INOUE YASUYUKI
IPC: B25J17/00
Filed: 1995-03-17
Abstract: PURPOSE: To obtain the gravity parameter with excellent accuracy by moving the specified section of a motor in the forward direction at a constant speed, moving the same section in the reverse direction, integrating the current in each movement, adding the respective integrated values, and estimating the link parameter on the gravity. CONSTITUTION: In the reciprocating motion of the first axis, other hinges are fixed so as not to make a movement. The gravity parameter is obtained by integrating the motion torque of the first axis when the second axis takes two kinds of positions. That means, a command is given to achieve the reciprocating motion of the specified section of the first axis at the constant speed with the second axis at the position θ21 . The integrated values of the torque command are ING1(T +) and ING(T) respectively. Then, the attitude of the second axis is changed, and the integrated values of the torque command are ING2 (T+) and ING2 (T-) respectively. The parameters I1 I2 are determined based on the sums of these values, i.e., Tg11, Tg12 and the formula, and the link parameter on the gravity is estimated.

Title: Ozone generating circuit
Inventor: SATO TERUO
IPC: H01T23/00
Filed: 1990-03-30
Abstract: PURPOSE:To obtain an ozonizer with a simple circuit constitution and without being significantly affected by humidity by controlling the output pulse width of a pulse generator in accordance with a silent discharge current. CONSTITUTION:The output of a pulse generator 1 is transmitted to the base of a transistor 2 to drive a pulse transformer 3. A creeping discharge body 4 is connected as the load of the secondary winding 32 of the transformer 3. When the primary winding 31 of the transformer 3 is driven by the transistor 2, a high voltage is induced in the secondary winding 32 of the transformer 3 immediately after the transistor 2 is turned off. A damped vibration is then caused at a frequency determined by the inductance of the secondary winding 32, distributed capacity, capacity of the creeping discharge body 4, etc. When a creeping discharge is started by the creeping discharge body 4, the vibration is superimposed on a damped vibration current, and a pulse silent discharge current is observed. The ozone generating circuit is controlled so that the detected output of a silent discharge current is fixed, and the creeping discharge is relatively uniformized.

IPC: G03B7/24
Filed: 1984-04-28
Abstract: PURPOSE:To prevent the titled signal input device from malfunctioning at a signal switching position of a digital code by providing a digital code generator for digital codes consisting of plural bits, a code variation detector, and a processor for digital code, and detecting code variation and controlling the operation of the processor. CONSTITUTION:The quantity of mechanical displacement of a dial set through external operation is transduced into an ON-OFF combinations signal of respective switches 3'-1, 3'-2,...3'-m, and 3'-n constituting a switch group 3'. A digital code generated with the switches 3'-1-3'-n is binary and a switch 20 is further provided to the group 3'. The relation between a position signal from the group 3' and a signal from an information circuit 6 is calculated by a processing circuit 5' to control a control circuit 7. The transient state of a changeover position where outputs of plural switches among the respective switches 3'-1-3'-n vary is detected by the switch 20 and if a detection signal is generated, the circuit 5' interrupts the processing and performs its original signal processing after the detection signal is ceased. Thus, malfunction is prevented.

Abstract: PURPOSE: To prevent any gas form depositing on an insulator by providing gas discharging switches at specified intervals between electrodes in a discharging region, an insulation region and a shielding region so as to limit the discharge positions along the discharging electric passage during electrically discharging range. CONSTITUTION: Plural coaxial electrodes 2, 3 having coaxial holes 5, 6 are provided, a gas discharging route 10 is formed within a central electrically discharging region 11 and an insulation region 13 is formed on the edge of the electrode 3.

The interval between electrodes 2, 3 is D in an electrically discharging region 11, d1 in the insulation range 13 and d2 in a shielding region 12, and intervals d1 , d2 are equal to each other and the interval D is made larger than intervals d1 , d2 . In addition, a means 18 for shielding an insulator 16 is provided in the shielding region 12. Owing to the abovementioned constitution, electrically discharging positions are limited inside of the electrically discharging region 11, particularly along a discharging route. Thus, gas deposition can be prevented because the insulator 16 cannot be seen directly.

Filed: 1992-04-08
Abstract: PURPOSE:To obtain a photosensitive planographic printing plate printing device for printing a mark for discriminating a printing color at a position which is not influenced even when the mark is printed at the time of printing. CONSTITUTION:A notched part 830 is formed at one part of an aperture at the lower edge of a light shielding hood 816, and what is called a color ball for discriminating the printing color of a color separation film is printed on a printing plate by light from the notched part 830. A closing plate 834 is disposed in the notched part 830, and allowed to move to a position where it closes the notched part 830 and a position where it opens the part 830 by driving a cylinder 842. A light shielding sheet 835A whose material is the same as a felt-like light shielding seal 835 attached to the margin of the lower edge of the hood 816 is attached to the leading edge surface of the plate 834. Since the same two images are usually recorded on a PS plate, the color ball is recorded simultaneously with printing either image. Therefore, at the time of printing the first image, the plate 834 is moved to the position where the notched part 830 is opened, and at the time of printing the second image, the plate 834 is moved to the position where the part 830 is closed.

Abstract: PROBLEM TO BE SOLVED: To efficiently receive spary by providing a delta-shaped sponson capable of receiving the spray jumping up by entering all the way from a ship's bottom surface, being adjusted in the outflow direction of the spray and having a width expanded in the stern direction on both-board side outside plates of a stern part. SOLUTION: A sponson 11 is formed in the shape of being adjusted in the outflow direction of spray S jumping up by entering all the way from a ship's bottom surface, and is actually formed in a delta shape capable of receiving the spray S jumping up by entering all the way from the ship's bottom surface and having a width expanded backward. This is because an inflow angle of the spray S is not parallel to ship side outside plates 7 and falls within a specific angle. Thus, the sponson 11 expanded backward as a widening width angle θ of 10 deg. to 15 deg. from the front end is desirable. Particularly, when the widening with angle θ of the sponson 11 is set to 15 deg., almost all spray S can be received.

Abstract: PURPOSE:To accomplish high transfer rate with which over-lighting can be directly performed by providing a semiconductor laser on a fixed part and monitoring an emitted beam and power by a fixed optical system so that the oscillation of pulse for erasing may be facilitated. CONSTITUTION:The semiconductor laser LD 3 attached to a chassis base 2 is directly connected to the driving stage 35 of an LD driving circuit 34. The laser LD 3 is shaped to be a collimated beam by a galvano mirror 7 and is projected from the fixed optical system 1 after detecting the emitted beam and power. Thus, a rise or fall time is shortened and the oscillation of laser for erasing is easily obtained, then the high transfer rate with which the over- lighting can be directly performed is accomplished. Furthermore, the optical system 1 detects a magneto-optical signal and a servo signal from the detected beam. The optical path of the laser is changed by the mirror 9 of a moving optical system 8 so that the laser is condensed on a recording film 12 of a magneto-optical disk 11 by an objective lens 10. The optical system 8 is mounted on a voice coil motor and moves between the innermost periphery 16 and the outermost periphery 17 of the recorded area of the disk 11.
