Title: Echo preventing loudspeaker telephone set
Inventor: TSUKUDAI AKIHIKO
IPC: H04B3/23
Filed: 1987-04-17
Abstract: PURPOSE:To remove an acoustic coupling signal detoured from a speaker to a handset and to prevent abnormal oscillation of the system by inserting a frequency converting circuit to an output section of an echo canceller so as to shift the frequency of the transmission signal sent to an opposite telephone set. CONSTITUTION:A signal coming from a speaker 2-2 by passing to a handset among signals inputted from a handset 2-1 is removed by an echo canceller 2-3 and shifted by several tens of Hz at a frequency converter 2-4 and the result is sent. The signal drives a speaker 2-8. The signal coming from the speaker 2-8 detoures the handset 2-7, but it is removed by an echo canceller 2-9. A frequency shift circuit is inserted to at least one side telephone set to shift the signal to a degree (several tens of Hz) not giving so much a sense of incompatibility by hearing so as to avoid the loop forming, thereby preventing abnormal oscillation.

Title: Electron gun
Inventor: IKEGAMI KAZUNORI
IPC: H01J29/50
Filed: 1985-04-30
Abstract: PURPOSE:To acquire a cathode-ray tube of superhigh resolution, by forming the center lens hole and the both side lens holes of an electrode which consists a main lens member, in different forms. CONSTITUTION:While the center lens hole 8b of a G3 electrode 4 is formed in a circle, the lens holes 8a and 8c of both sides are formed in an ellipse with the vertical size larger than the width. Since the width of the both side lens holes 8a and 8c of the G3 electrode 4 in the main lens member is made smaller than the diameter of the center lens hole 8b, the horizontal curvature in the same potential surface is larger in the side lenses than in the center lens. Therefore, the horizontal focus properties of the center lens and the side lenses can be unified by adjusting the focus property of the side lenses. In such a way, the spot form of both the center beams and the side beams can be adjusted to be in the same circular form.

IPC: B21K3/04
Filed: 1995-04-20
Abstract: PURPOSE: To straighten a blade automatically by providing a measuring head, a holding head, a pressing head, and an arithmetic control means connected to a Z-axis direction moving means. CONSTITUTION: An arithmetic controller (CPU) compares the previously inputted data of a blade 5 with the measured data measured by a measuring head 4 and computes the distortion quantity every specified Z-position. The holding head 2 is then moved into the specified position of the base end part of the blade 5, and the Z1 position of the blade 5 is clamped by the operation of the workpiece clamp cylinder of a pressing head 3.

Title: Expandable suspending tool and crane
Inventor: MAKINO KAZUHISA
IPC: B66C1/10
Filed: 1989-04-17
Abstract: PURPOSE:To obtain an expandable suspending tool having the simple constitution by installing a link means for making the interval between the suspending blocks substantially equal to the interval between the parts of an expandable means. CONSTITUTION:The both edges in the longitudinal direction of one suspending block 52 and the both edges in the longitudinal direction of the other suspending block are connected by the bendable link means 60 and 60. Since the distance between the connection parts of the suspending blocks 52 and 52 connecting one link means 60 and the distance between the connection parts of the suspending blocks 52 and 52 connecting the link means 60 can be made equal, the suspending blocks 52 and 52 shift in parallel, accompanied with the extension and contraction of the rod ol a motor-driven cylinder device 53. Since two beams of the conventional suspending beam and a guide installed onto a main frame can be operated only by the link means 60, simple constitution can be obtained at a low cost.

Title: Machine tool with vertical enclosing wall, usage of machine tool
Inventor: IKEDA KUNIHIRO
IPC: G05B19/418
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To keep a work in the closing state with a cover body until it is pushed out to a work placing table after machining as well as the course of machining to prevent contamination of the surroundings by closing the work placing table and a work passing opening of the vertical enclosing wall with the cover body. SOLUTION: The operation of a hydraulic cylinder device 23 is to oscillate a cover body 17 upward round fulcrum shafts 20, 20, whereby the cover 17 is put in the closing state of covering the upper space of a work placing table 13 and a work passing opening a1. At this time, as the driving force of the hydraulic cylinder device 23 is small, the cover 17 will not strongly press the hand or the like to prevent an operator from being injured. During machining, a cutting liquid is scattered in the surroundings due to the rotation of a spindle 5 or the like. At this time, cutting oil inhibited from being scattered outward by the vertical enclosing wall, the cover 17 and a lower enclosing wall 8 flows down on the upper surface of the machine table 2, and further recovered to a specified portion to be circulated and used.

Title: Video transmission method and its system
Inventor: KATSUTA NOBORU
IPC: H04N19/00
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To allow a system to select optimum image quality data and to reproduce the selected data in response to reproduction processing capability even when data of the same video image with different image quality are transmitted like in simultaneous broadcast. SOLUTION: A base image is given to a base coding section 1, and a high resolution signal is given to a reinforcement signal coding section 2 codes a difference of the base image. Each encoder section transfers a macro block number coded without skipping I frame each to a coding macro block number detection sections 5, 6, and a multiplexer section 3 applies TS-stream multiplex to base and reinforcement signal data and each coded macro block number and transmits the resulting data. An MPEG decode processing section 7 at a receiver side gives information of current arithmetic processing capability to a multiplexer/demultiplexer section 4, where the received data are demultiplexed into the base data and the reinforcement signal and selects the data depending on the macro block processing capability and gives the selected data to the MPEG decode processing section 7.

Title: Prediction decoding device
Inventor: HOSHI NOBUHIRO
IPC: H04N19/65
Filed: 1990-04-10
Abstract: PURPOSE:To obtain a decoded value as a value very close to a sampling value by replacing a decoded value corresponding to a coding code resulting from a code error which is disabled of correction during the decoding into other value and using the replaced decoding value to generate a prediction value. CONSTITUTION:A switch 128 is normally connected to the position A, a decoded value outputted from an adder 123 is outputted as an output decoded value and fed to a prediction device 125. A prediction device consists of a D flip-flop delaying a data by, e.g. one sample period and uses a decoding value of a just preceding period as a succeeding prediction value. An error correction circuit 117 upon the detection of a code error disabled of correction generates an error flag and the switch 128 is connected to the position B attended therewith. Thus, a prediction value is outputted from the switch 128. The prediction device 125 employing a D flip-flop delaying one sample period outputs a just preceding decoding value. Since the prediction value and the decoding value have a very strong correlation, an error caused therein is small.
