Title: Amplifier circuit
Inventor: ERUNSUTO RINKUSHIYUTETSUTO
IPC: H03K5/02
Filed: 1988-11-07
Abstract: PURPOSE: To reduce current consumption and to increase an input impedance by controlling a current of a current sink with an output signal of an amplifier or conversely allowing the current sink to supply a constant current and controlling the current of a current source with an output signal of the amplifier. CONSTITUTION: A current from a constant current source I1 and a current whose direction is reverse to that of the constant current are fed to an input E of an amplifier V. The absolute value of the current other than the constant current fed to the input side of the amplifier V is smaller or larger in comparison with a constant current from the constant current source I2 . The current supplied to the input E of the amplifier V comes from the current source I2 and the current is controlled by transistors(TRs) T1 , T2 . A TR T3 is controlled by an output signal of the amplifier V to be conductive or nonconductive. Thus, the current consumption is decreased and the input impedance is increased.

Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent a liquid metal from being leaked through a clearance by sealing the clearance between a plug and a small hole with a reaction film generated by a reaction with the liquid metal. SOLUTION: A lid body 2 has a small hole 6 for filling a liquid metal 4 formed in the part opposed to the end surface of a shaft 3, and this small hole 6 is blocked by a plug 7.

Title: Welding groove position detecting method
Inventor: HONDA KAZUHIKO
IPC: B23K9/127
Filed: 1991-10-25
Abstract: PURPOSE:To correct the proceeding direction and to carry out sure profile control by automatically changing a window to detect the deviation when a drag angle of a torch is changed and profiling is deviated in performing welding work to profile a weld line by a robot. CONSTITUTION:The shape A of arc light is picked up on an image from above a welded joint line and a welding reference line R is detected by a projection (a) from the picture. When an angle (drag angle) formed between the reference angle R and the torch T becomes larger, a projection (b) is generated on the shape A. When it is determined that the positional deviation exists from the locus data, the window W is automatically changed to W' to carry out scanning. Consequently, (a) and (b) are discriminated from each other and the reference line R is accurately detected.

IPC: H04L12/40
Filed: 1987-11-05
Abstract: PURPOSE:To improve the efficiency of information gathering due to simultaneous multi-address communication by providing commands which require responses and commands, which do not require responds if reported, as commands by which a terminal gathers the state of the attribute or the like of another terminal. CONSTITUTION:When a controller 31 connected to a transmission line 30 transmits the text of an attribute register request command 11 onto a transmission line 30 by simultaneous multi-address communication, terminals b33-n35 transmit back an attribute register response command 13 to the controller 31 to gather attributes of terminals. A newly provided attribute register request supplement command 12 is periodically transmitted. Terminals b33-n35 which already receive the attribute register request command 11 and already transmit back the attribute register response command 13 to this command 11 do not respond to the attribute register supplement command, and a terminal a32 which cannot receive the preceding attribute register request command 11 by some cause transmits back the attribute register response command 13.
