Title: Hand for picking up plate workpiece
Inventor: IWATA YOSHIHARU
IPC: B25J15/06
Filed: 1991-06-21
Abstract: PURPOSE:To provide a hand for a manipulartor in which a plate workpiece is gripped so that a vertical coordinate value of the position of the plate workpiece in a three-dimensional space is fixed at a predetermined value, and the workpiece position a two-dimensional coordinate is caught by a camera so as to know a difference between it and a reference workpiece position in a two-dimensional coordinate, and the difference is corrected so that the workpiece is carried to a next process. CONSTITUTION:A first workpiece gripping means 20 that is not moved laterally, and a second workpiece gripping means 40 that can be moved laterally, are provided on a hand frame 12, while lifting of a plate workpiece W by means of the gripping means 20, 40, the gripping, and the workpiece position in the vertical coordinate direction are set by vertically moving cylinder 22, 42, and a reference position HL of the set workpiece W is found by a camera 60 and a difference between it and a reference position taught is found, and the workpiece is carried to a next process and is positioned so that the difference is corrected. Since the working position is known not in a three-dimensional mode but in a two-dimensional mode, the carrying to the next process and the positioning are simplified, and the cost is reduced thereby.

Filed: 1984-07-18
Abstract: PURPOSE:To improve the random correction capability and to simplify the constitution of a coder by switching the state that coding/decoding is applied so that an error correction code and/or error detection code are finished in one group and coding/decoding is applied so that they are finished over plural groups. CONSTITUTION:A switch 14 is switched with a signal in 16.67Hz synchronously with the rotation of a drum 31 from a timing control circuit 33, a PCM signal is fed alternately to the 1st RAM15 and the 2nd RAM16 at each rotation of the drum 31, the PCM signal is split into each 8-bit high-order and low-order symbols and written in the 1st RAM15 or the 2nd RAM16. In this case, the location in the RAM written with the information symbol is controlled by a write address control circuit 23 and then address selection switches 25, 26 are switched alternately synchronously with the switch 14.

Title: Electrophotographic apparatus
Inventor: KASUGA MUNEO
IPC: G03G15/00
Filed: 1979-11-22
Abstract: PURPOSE:To prevent the image degradation at the time of reiteratively transferring the sensible images by the once formed latent images to transfer paper which is broader than photoreceptor by removing the unnecessary charge of the end parts of the photoreceptor through light radiation. CONSTITUTION:Lamps 41, 42 are lighted by way of a transistor 46 which conducts at required timings and only the required regions at the end parts of a photosensitive drum 9 are irradiated through slits 43A and 43B, 44A and 44B. As a result, the unnecessary charge accumulated in the end parts of the drum 9 is removed by the concentration of power lines at the transferring, while the next transfer is being carried out after the transfer has been made on recording paper wider than the drum 9 via a transfer roller 20. Hence, the staining that occurs in the parts corresponding to the end parts of the drum 9 of the recording paper 15 at the next transfer by the unnecessary charge is prevented and the images at the reiterative transferring of the sensible images based on the once formed latent images are of good quality free from any stains at both end parts.

Title: Alternating constant-current circuit
Inventor: OKAYAMA TSUTOMU
IPC: G01R33/381
Filed: 1991-06-24
Abstract: PURPOSE:To obtain an economical alternating constant-current circuit which makes it possible to speed up the switchover of load current and control the value of the load current precisely, by changing the AC output voltage level of a switching power source using a transformer. CONSTITUTION:When switches S1 and S4 are opened, load current flows through diodes D2 and D3 and attenuates. And if switches S2 and S3 are closed at a point when this diode current becomes zero or a little before that, the load current changes its direction, rises, and reaches a constant value. The diode current charges a capacitor C1 and increases its voltage. Namely, the excitation energy of the load Lx is collected in the capacitor C1. In the process of recovering the excitation energy, the diode current flows in a resonance circuit comprising the inductance Lx and capacitor C1. And the terminal voltage Vc of the capacitor C1 jumps up if the Q of the resonance circuit is large.

Abstract: PURPOSE: To make the automatic changing of welding specifications possible by addition of a small sized control device to a standard type welding machine by shifting the  phase of firing pulses by the rotation of potentiometers applied with constant voltage,  and changing the wirings of devices regulating welding voltage and current.   
     CONSTITUTION: When a potentiometer (expressed hereinafter as meter) VR 1  is manually  operated, a difference is produced in both input voltages between sliders of the meters  VR 1 , VR 4 , that is, a differential amplifier Q 2 , and the meter VR 4  is rotated to the  elimination of said difference. The meter VR 5  interlocked to this is also rotated, and  since the input of a circuit 22 is proportional to the slider voltage of the meter VR 1 ,  the set value of the meter VR 1  can be recorded in a memory 23 in digital value. When  all the interlocked switches S 1 WS 6  are changed over at the welding, the output of the  memory 23 converted in a circuit 24 and the output of the meter VR 5  input to the  amplifier Q 2 . The meters VR 5 , VR 4  are rotated to the elimination of this difference  and when the switches S 1 WS 3  are changed over at this time, the meter VR 1  and a  voltage follower circuit Q 1  go idle,and the meter VR 4  is activated and therefore a  voltage regulating circuit A controls the welding voltage by means of the output of  the meter VR 4 , that is, the recorded value of the memory 23.

IPC: H04N9/73
Filed: 1989-06-14
Abstract: PURPOSE:To improve the accuracy of automatic white balance by comparing a signal level formed based on an image pickup signal fed to a signal processing circuit with a reference level and inputting a nearly white level picture element data to an integration means selectively based on the comparison so as to obtain an integration output. CONSTITUTION:A white level detection circuit 18 applies integration only when a signal level of color synthesis signals CR, CB does not exceed a reference level to obtain an integration value of a data of nearly white level picture element. Threshold levels CRA, CRB as reference levels in response to the change in the level of a luminance signal Y for each picture element are set to the white level detection circuit 18 and integration is implemented only when the level of color synthesis signals CR, CB does not exceed the threshold levels CRA, CRB and no integration is implemented if exceeding. Thus, only a picture element with nearly white level is detected and the data is integrated, then the accuracy of automatic white balance is much improved.
