Title: Base band signal compounding circuit
Inventor: MUROMOTO ATSUSHI
IPC: H04B7/02
Filed: 1979-02-22
Abstract: PURPOSE:To eliminate the control signal combined to the main circuit by having the subtraction between the composite signal of the main circuit and the composite control output of the auxiliary circuit via the differential circuit, thus improving the S/N ratio for the base band low band. CONSTITUTION:The diversity reception signal is demodulated at receivers 11 and 21 via antennas 10 and 20, and then changed into the base band signal to be applied to relative square attenuators 12 and 22. Control voltage generators 13 and 23 apply the control signals obtained from the AGC signals and others sent from receivers 11 and 21 to attenuators 12 and 22 via low band pass filters 14 and 24. The composite signal of the main circuit obtained through composition of the output of attenuators 12 and 22 plus the composite control output obtained through composition of the output of compounding auxiliary circuits 15 and 25 are connected to differential circuit 31. Circuit 31 delivers the reception signal with perfect elimination of the control signal contained in the composite signal of the main circuit to terminal 30.

Title: Function trimming device
Inventor: FUJIWARA YASUO
IPC: H01L27/01
Filed: 1988-01-29
Abstract: PURPOSE:To accelerate trimming by stopping the trimming when comparing and discriminating means detects the coincidence of the state of a signal to be trimmed with that designated by a reference signal during the trimming. CONSTITUTION:A resistor or the like of an element 1 to be trimmed is radiated with a laser beam L while comparing a voltage to be trimmed corresponding to a frequency generated from the element 1 to be trimmed with a reference voltage Vx by a voltage conversion comparator 9, thereby performing rough regulation trimming. The voltage to be trimmed gradually approaches the voltage Vx as the radiation of the beam L, and when both becomes equal, a comparison signal Vf applied from the comparator 9 to a CPU 11 arrives at a predetermined threshold value level, and the CPU 11 stops radiating of the beam L. Thus, since the CPU 11 is interrupted by the comparison signal Vf output when the voltage to be trimmed coincides with the voltage Vx, it can be trimmed while radiating the element 1 to be trimmed with the beam L, thereby shortening the time required for the trimming.

Filed: 1991-01-21
Abstract: PURPOSE:To prevent deformation of a weak part and also dislocation when taking-out is made with an external force by furnishing an air blowup path in a supporting table on which parts are placed. CONSTITUTION:The arm 32 of a transport mechanism 30 for taking-out of parts 12 is moved, and an attraction part 38 is positioned a little over an applicable piece of parts, and compressed air is fed from a compressor 26 to a blowup path 22. The compressed air blows off upward from the tip of this blowup path 22 which opens at the inner bottom of the parts placing part 14, and the piece of parts 12 is blown up by the fluid pressure. Because the distance between the piece of parts 12 and the attraction part 38 is small, the oversurface of the piece contacts the undersurface of the attraction part 38 at once. A vacuum generator 44 is actuated at the same time as feeding of the compressed air from the compressor 26 so as to put inside of the suction path 40 under a negative pressure. Thereby the piece blown up by the compressed air and having contacted the attraction part 38 is attracted to its undersurface.

Abstract: PURPOSE:To realize the rewriting under the control of a controller and to reduce the load of a main body device, by adding a function to the controller of a terminal device to count the number of bytes in case the data supplied from an external storage device is read. CONSTITUTION:The number of bytes which is read through the reading of the data given from an external storage device is counted at and after the head of the data block, and an overrun is detected. In such case, the count value of the byte number obtained when the overrun occurs is stored in a counter storage 13, and the address obtained when the overrun occurred is held at the memory address of a main body device side. Then no data is transferred when the data block having an overrun is read again until a coincidence is obtained between the byte number obtained by counting at and after the head of the block and the byte number stored in the storage 13. The reproduced data is transferred after a coincidence is obtained between both byte numbers. As a result, no overrun is substantially caused when viewed from the side of the main body device.

Abstract: PURPOSE:To adjust a micro notching quantity with high accuracy by controlling a driving circuit on the basis of the detecting signal for detecting the contact noise of a tool and a material to be cut with an AE sensor, and outputting the voltage corresponding to the predetermined notching quantity from the driving circuit. CONSTITUTION:When a tool 1 does not contact to a material 9 to be cut, an AE sensor does not output, and the tool 1 is fed to the cutting direction by a piezoelectric element 2, and the detecting signal S1 of the AE sensor 3 is generated at a point that the tool 1 starts to contact to the material 8 to be cut.

Abstract: PURPOSE:To easily obtain a long-sized ceramic body which is less deformed by hanging long-sized bodies of unsintered ceramic compacts in a sheath and subjecting these bodies to primary calcination, turning of the long-sized bodies upside down and subjecting the bodies to secondary calcination. CONSTITUTION:A sintering assistant, org. binder, water, etc., are added and mixed to and with ceramic powder and after the mixture is molded, the moldings are dried and calcined to form the long-sized calcined compacts 1 which are the unsintered ceramic compacts. Separately, two pieces of square columnar supporting rods 3 are spanned nearly in parallel at a prescribed spacing at the top end face of the blind cylindrical sheath 4. Needle-like hanging pins 2 are penetrated into the through-holes formed at the ends of the calcined compacts 1 and the calcined compacts 1 are subjected to primary calcination in the stage of hanging these compacts within the sheath 4. The sintered compacts obtd. in such a manner are in such a state being turned upside down, and are hung down and are subjected to secondary calcination. As a result, the large camber generated on the lower side of the sintered compacts obtd. by primary calcination is corrected by pulling the long-sized bodies 1 downward by their own weight in the secondary calcination.
