Title: Moving picture encoding transmitting device
Inventor: TAKANO HIROSHI
IPC: H04N19/423
Filed: 1990-04-27
Abstract: PURPOSE:To reproduce a more natural moving picture with smooth movement and small, distortion by removing a high frequency distortion component with lowering cut-off frequency when the encoding distortion is large and reproducing an original high frequency signal component with returning the cut-off frequency to a normal value when the encoding distortion is small. CONSTITUTION:An encoder 24 compress-encodes a differential signal between flames from a subtracter 8 according to fixed algorithm and a distortion value signal generating part 25 is built in the encoder 24 and generates an encoding distortion value signal to indicate the quantity of encoding distortion generated at encoding. Besides, a receiver 2 provides a low-pass filter 28 able to control cut-off frequency to filter a decoding video signal and controls the cut--off frequency of the low-pass filter 28 based on the encoding distortion value signal to indicate the generating quantity of the encoding distortion generated at the encoding. That is, when the encoding distortion is large, a high frequency distortion component is removed with lowering the cut-off frequency and when the encoding distortion is small, an original high frequency signal component is reproduced with returning the cut-off frequency to a normal value. Thus, a more natural moving picture can be obtained.

Title: Pulse arc welding device
Inventor: UKAI JIYUN
IPC: B23K9/09
Filed: 1980-08-19
Abstract: PURPOSE: To carry out stable pulse arc welding producing no spatters by supplying a consumable electrode at the time of large current in synchronizating with welding current pulses and stopping the same at the time of small current.  
     CONSTITUTION: The pulses of the pulse frequency set by a variable resistor 10 are transmitted from an A/D conversion circuit 11 to a switching element driving circuit 12. At this time, the pulses which are the same as or synchronized with said pulses are applied as an input signal for a motor driving circuit 14a, and a pulse motor 9a is controlled by the circuit 14. Hence, in synchronization with the welding current, the motor 9a is driven only at the time of pulse current to feed a wire 4 toward objects 7 to be welded. At the time of base current, the motor 9a is stopped to stop feeding the wire 4. Then, when the length of an arc 6 is short, the wire 4 is not fed at the time of base current and therefore it will not plunge to the objects 7, and the formation of spatters of large particles is obviated.

CONSTITUTION:A striking section 24 is formed in arcuate shape corresponding to the radius of a pin 9 for striking points, the rotating locus, and the center passes through the center of revolution 0 of the split piece 7 and is biased at  an angle theta to a straight line L parallel with the spacing direction of the carriage 2. The pins 9 succesively pass in front of the striking section 24 through the revolution of the revolving body 6, the striking section 24 drives selectively the pins 9 at timing reaching each line position of a dot matrix, and one row of the dots are formed selectivly. One character is shaped by the passage of the five pins 9 through the character formation of five rows and seven lines. When the pins 9 pass in front of the striking section 24, the pins 9 right advance through the spacing of the carriage 2. Accordingly, printing is enabled at high speed while disturbance is not generated in the arrangement of the dots.

Filed: 1980-08-19
Abstract: PURPOSE: To reduce the weight of a rotary ring and improve its load carrying capacity etc., by  fitting a split inner orbital race and outer orbital races on the peripheral surface of an inner race  and the inside surfaces of outer races and providing rolling elements among the inner and the  outer orbital races so that each rolling element is in four-point contact with the orbital races.   
     CONSTITUTION: A split inner orbital race 7 and an upper and a lower outer orbital races 8, 9,  which are made of quench-hardened bearing steel, are fitted on the peripheral surface of an inner  race 4 and the inside surfaces of outer races 5, 6. The races 4, 5, 6 are made of nonferrous metal  or the like. Rolling elements 10 are arranged among the orbital races 7, 8, 9 in contact with their  orbital surfaces 28a, 28b, 30, 32 to provide a constrution similar to that of what is called four- point-contact angular ball bearing. A rotary ring 1 consisting of a main body 2 and a bearing  section 3 has low weight because the inner and outer races 5, 6 of the main body 2 which shares  most of the entire weight of the rotary ring 1 are made of a light material. The orbital race 7 etc.,  which are fitted on the inner an outer races etc., are machined with high accuracy as well as an  ordinary bearing to avoid distortion and deformation to accurately assemble the main body 2 and  the bearing section 3 with each other. This results in providing the rotary ring 1 with high load  carrying capacity and good dimensional accuracy.

Title: Soil improvement method and tools used for the same
Inventor: ENDO TOKUHIRO
IPC: E02D3/12
Filed: 1994-04-28
Abstract: PURPOSE:To enhance the penetration effect by inserting a bar space reducing the sectional area of a steel pipe buried in the ground and injecting a solid- improving liquid to the depth at a high speed and high pressure. CONSTITUTION:When a valve 20 is opened and a soil improving slurry is injected from an injection device, the soil improving slurry is fed to the depth of a hole 2 through the clearance between the inside face of a steel pipe 3 and the outer peripheral face of a spacer pipe 10. Next, the soil improving agent is delivered from the opening 3b at the depth of the steel pipe 3 and a number of pierced holes 5 on the way to penetrate into the ground. In this case, since the pipe 10 is inserted, the inside section of the steel pipe is reduced and hence the soil improving agent is injected at a high speed and high pressure and effectively delivered into the ground 1 to penetrate in the ground. When it is necessary, partitioning bags are wound on the spacer pipe with a specified distance, to inject the soil improvement material into respective partitioned parts for even injection to penetrate the soil in a vicinity of the hole bottom of the ground equally. In this way, the penetration effect can be enhanced and after operation, the residual soil improvement agent left in the pipes can be reduced.

Abstract: PURPOSE:To widen a processable region by disposing aspherical lenses which make uniform the sectional intensity of the laser beam emitted from a laser transmitter and plural rows of condenser lenses on the plane in the optical path of the laser beam made uniform by the above-mentioned lenses. CONSTITUTION:The sectional intensity distribution of the laser beam 2a having a gauss distribution is made uniform by using the aspherical lenses 3, 4. The uniformized laser beam 2b is projected to a condensing optical device 8 constituted of several pieces of the condenser lenses 11.

The uniform processing of even the central part and peripheral part of the processing region is possible in this way and further, the effective utilization of the greater part of the energy of the laser beam for processing is possible and, therefore, the processable region is widened.
