Title: Direct current welding electric power source device
Inventor: NISHIDA YORIAKI
IPC: B23K9/06
Filed: 1979-06-18
Abstract: PURPOSE: To decrease the weight and size of the device and performs its economical output controlling by enhancing the use frequency of a main transformer with an inverter circuit of sufficiently decreased frequency variable range which performs output change and decreasing the weight of the main transformer and reactor.  
     CONSTITUTION: A transformer Tr is connected as load of the inverter part to which direct current inputs and the secondary side output thereof is full-wave rectified by way of an AC reactor L 1 . Arc load is connected between their outputs. As a result of this, the full-wave rectified output decreases or increases with an increase or decrease in the inverter frequency, but if this frequency is made sufficiently larger than the commercial frequency, the commutation loss of the inverter part becomes large. Because of this, the variable range of the foregoing frequency with respect to a desired ouput range is made much smaller. Namely, the inverter quiescent time when the switching elements Q 1 WQ 4  to obtain minimum outputs are all turned OFF is made slightly less than half the period of the maximum inverter frequency and this set time is employed in a much lower frequency region, whereby the output is made constant.

IPC: G03G15/043
Filed: 1982-05-11
Abstract: PURPOSE:To stop an original plate in a desired position with high accuracy, by applying a voltage of a reversed polarity to a DC servocontrol motor which moves and drives the original plate thereby generating brake torque. CONSTITUTION:A motor controlling circuit 10 is controlled with a microcomputer 8 in response with a counter 9 or the like which performs counting according to the number of revolutions of a DC motor 11 in accordance with a variable magnification or the like, whereby the motor 11 is subjected to DC servocontrol and the original plate of a copying machine is moved. When the prescribed movement of the original plate is detected with a sensor associated with the stop position, the motor 11 is controlled for a prescribed period by the voltage of a reversed polarity with the computer 8. The torque in the reverse direction outputted by the motor 11 acts as brake torque on the original plate and the original plate is stopped in a desired position with high accuracy.

Title: Thermal printer
Inventor: ARAI KENJI
IPC: B41J2/52
Filed: 1991-04-10
Abstract: PURPOSE:To provide a simple circuit structure without duplex configuration of memory by employing a dynamic RAM memory having a page memory, in a printer wherein a heat generating resistor of a thermal head is energized for a time of integer multiple of a unit time so as to output images including intermediate tone. CONSTITUTION:A frame memory 1' is constituted of a dynamic RAM memory capable of reading out a page mode. A read out control circuit 2' outputs a line address signal RL. In this state, a RAS signal designates a line i of the memory 1' and addresses of each picture element of 1 line are outputted successively. In accordance with a CAS signal synchronizing with this, image data of each picture element of the line i are outputted to a comparator 4 successively so as to be compared with a count value of a counter 5. When the outputting of the image data of each picture element in the line i is completed, the line i is designated again so that the image data is read out. This is repeated for the number of density gradations so that image of the line i is outputted and a next line process starts.

Title: Superconducting switching element
Inventor: TAKEMURA YASUHIKO
IPC: H01L39/24
Filed: 1990-03-27
Abstract: PURPOSE:To form a superconducting element in which carriers in a metal layer are injected excessively into a superconductor and whose superconducting state is destroyed and transformed into a resistance state by a method wherein, at the temperature of a superconducting critical temperature or lower, a voltage is applied across an upper-part electrode and a lower-part electrode. CONSTITUTION:A gate voltage is first applied to a switching element; the part between B and E is set to a resistance state. Then, an electric current is made to flow. Since parts other than the part between B and E are in a superconducting state, the electric current flows in the path of A B C D E F. When the gate voltage for the switching element is set to zero, it seems that apparently no electric current flows between B and E. In reality, electric currents of the same magnitude in opposite directions of B E and E B is flowing. Lastly, when an external electric current is cut, the electric current of B E does not flow between B and E, and only the electric current of E B flows. After all, the loop of a closed persistent current of B C D E is left; it is a memory state. A memory readout operation can be executed when a magnetic flux generated by the closed persistent current is read out by another superconducting element.

CONSTITUTION:In a host computer 1, from an output image derived in accordance with a program which has been read out of a large capacity memory 2, a weighting coefficient for putting a shading to its image when a light source has been installed at a specified position with respect to its output image is derived, and it is stored in a shading coefficient (SC) memory 8. This stored SC is supplied to an image converting circuit 5, and an output image data is obtained as a data to which its weighted shading has been performed. In this case, in case when the image is a data of a monochrome, the luminance level is made variable by the SC, and in case when it is a color image, the hue is changed. Also the SC is derived from the inner product of a normal vector of a plane containing at least three pieces of data and a vector going toward the direction of the light source.

Title: Stain detector for distance measuring device
Inventor: AKASU MASAHEI
IPC: G01S17/93
Filed: 1993-04-05
Abstract: PURPOSE:To judge the stain of a light transmitting path without providing a special stain detecting circuit, and to detect the lowering of a distance measuring function by measuring the frequency of a nondetected object based on the rate of the nondetected object to the number of distance measurement. CONSTITUTION:A distance measuring means 31 in a processing circuit 3A measures a distance to an object 7 on a time from light sending carried out by a light sending section 1 till light receiving carried out by a light receiving section 2. In this case, an object detecting means 32 judges whether the object 7 has been detected or not on a light receiving signal at every time when a light receiving element takes in light, but when a stain adheres to the light transmitting path (light sending and receiving windows 4, 5) of light receiving and sending sections 1, 2, the detection of the object 7 at a short distance is not influenced, but the object at a long distance can not be detected. A stain judging means 33 obtains the frequency of the nondetected object based on the rate of the number of nondetected objects to the number of distance measurement, and the stains of the windows 4, 5 are judged on the above frequency. When the rate of the frequency of nondetected object is above 0.8, the distance measuring capacity is judged to be lowered by the adhesion of the stain.

Abstract: PURPOSE:To make it possible to surely cut and transport of a massive substance, by interposing a massive substance defibering box larger than a diameter of a transport pipe between suction opening of an impeller casing and termination of the transport pipe, and loosening the transferred massive substance once. CONSTITUTION:A rotary cutting edge 28, fixed cutting edge 29, feed blade 30 and stir blade 31 are disposed in one body in front of an impeller casing 15. And a massive substance defibering box, whose diameter D1 is remarkably longer than a diameter D2 of a transport pipe 20, is interposed between the suction opening 16 of the impeller casing 15 and termination of the transport pipe 20. Accordingly, transport article such as mud which contains the massive substance of large diameter and high viscosity supplied from the transport pipe 20 to the front box 19, is loosened due to tensile force applied to its outside, since transport pressure is suddenly reduced in the massive substance defibering box 19, and its transportation can be facilitated. Therefore, it is possible to easily and surely cut the massive substance with the cutting edges 28, 29 and to prevent its adhesion to the cutting edges 28, 29 and an impeller 14.
