Title: Height measuring method, height data processing method, and height measuring device
Inventor: OKABAYASHI MITSUMASA
IPC: G01B11/30
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a height measuring method significantly improve in processing cycle time (tact time), thus allowing precise height measurement. SOLUTION: The height of a cream solder part printed on a wiring board is measured by light-section method. A first line beam is projected to a flat part near the cream solder to take its image 112. A second line beam is successively projected to the cream solder part to take its images 113a, 113b. On the basis of the height of the flat part determined from the first line beam image 112, the height of the cream solder part 113a is determined. According to this structure, since the height data of the cream solder part 113a is determined on the basis of the height data of the flat part 112 different from the flat part 113b having the cream solder formed thereon, it is not required to find the height data of the flat part 113b prior to the printing of the cream solder, and the processing cycle time can be remarkably improved.

IPC: B29C45/02
Filed: 1994-03-15
Abstract: PURPOSE:To seal a semiconductor device with resin without requiring any molding die by masking a lead frame except the part to be sealed and spraying an atomized resin paint while applying high voltage thereby coating the part to be sealed with the resin. CONSTITUTION:A high voltage is applied to a spray gun 20 and a high field 26 is established between the spray gun 20 and a lead frame 24. The spray gun 20 sprays atomizing air 21 and a resin paint 22. The resin paint 22 is atomized by the atomizing air 21. The atomizing air 21 and the atomizes air 22 sprayed from the spray gun 20 migrate toward the lead frame 24. The microparticle in the resin paint 22 is charged negative by a negative ion and migrates through the high field 26 toward the unmasked resin sealing part of the lead frame 24 which is thereby coated with the sealing resin. This method allows resin sealing of a semiconductor device without requiring any molding die.

Title: Interference detection circuit
Inventor: KAWAMURA SHOICHIRO
IPC: G01S7/36
Filed: 1990-02-23
Abstract: PURPOSE:To detect the presence of an interference wave with high resolving power by detecting the amplitude difference between the phase difference signal of a transmission signal and the receiving signal being the reflected wave thereof and the delay signal thereof. CONSTITUTION:The receiving signal of a receiving circuit 1 and the self-transmission signal received by a receiving circuit 2 are inputted to a phase difference detection circuit 3 and a video signal having amplitude proportional to position difference is outputted. If the receiving signal is the reflected wave of a transmission radio wave emitted by self, the phase difference between both signals is constant and, therefore, the output amplitude thereof becomes constant. When the signal received by the circuit 1 is an emission signal other than self, since frequency is slightly different in usual, the phase difference is changed with the elapse of time and output amplitude changes. Therefore, the amplitude difference is compared with a delayed signal by a differential amplifying circuit 5 and, when the output is 0, an interference wave is judged to be absent by an interference judging circuit 6 and, when the output does not become 0, the interference wave is judged to be present. By this method, the restriction of resolving power due to the expanse of a frequency spectrum based on pulse modulation is not received.

Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To more efficiently perform the work of separating the surface layer material of a sheet-like multilayer base material by moving a separating claw toward the surface layer material of the multilayer base material in a state of the tip of the separating claw abutting on the end surface of the multilayer base material. SOLUTION: A working unit 22 is energized to the mounting side of a separating claw 1 by the elastic force of an elastic body 26, whereby the end surface of a multilayer base material 2 is pressed by the tip of the separating claw 1. At this time, the separating claw 1 is elastically deformed by its own spring elasticity. A pressure rising cylinder 17 is actuated in this state to raise the working unit 22. When it reaches above the multilayer base material 2, the separating claw 1 is released from the drag from the multilayer base material 2 and moved toward the tip side by the elastic force, and its elastic deformation is solved. According to this, the surface layer of the multilayer base material 2 is flicked by the tip of the separating claw 2, and the end part of the surface layer material is separated. In the after treatment, the whole surface layer material is separated.

IPC: H04N9/78
Filed: 1993-03-05
Abstract: PURPOSE:To reduce the storage capacity of a memory for obtaining a frame delay signal by storing a digital signal whose lower bit is eliminated. CONSTITUTION:A decoding television signal converted into the digital signal is supplied to a bit elimination circuit 32 and an adder 34 through an input terminal 31. The bit elimination circuit 32 eliminates the lowest bit of a signal quantized by eight quantization bits, for example, and outputs highest seven bits to a frame memory 33. The frame memory 33 delays the decoding television signal of seven bits by one frame period and outputs it to an adder 34. The adder 34 adds the signal of eight bits at present time, which is inputted from the input terminal 31, with the output of the frame memory 33 being the signal of highest seven bits, which is prior by one frame period, by corresponding bits, and outputs an obtained two-fold Y signal to a coefficient unit 35. The coefficient unit 35 decreases the Y signal inputted from the adder 34 by 1/2, and outputs it to a mixer through an output terminal 36 as a still picture Y signal.

Title: Control saturation thin-film magnetic write head
Inventor: DEEBUITSUDO YUUJIN HAIMU
IPC: G11B5/23
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To make a writing magnetic field constant even in a large-current range by forming a magnetic yoke layer so that its width can gradually increase toward a flare point from a zero-throat point. SOLUTION: A thin film magnetic head is provided with a first magnetic yoke layer 32 and second magnetic yoke layer 34. The layers 32 and 34 are separated from each other by insulating layers 35, 36, and 37 except a rear gap area 38 and, in the front end area 39 of an electrode, the layers 32 and 34 form a conversion gap 41, because the layers 32 and 34 are separated from each other by a thin layer 40 composed of a nonmagnetic material. Since the width of the front area 39 gradually increases toward a flare point 46 from a zero-throat point 45, the magnetic flux density becomes uniform over the whole section between the points 46 and 45 and the whole section is abruptly saturated with a single current.  Therefore, the magnetic filed in a gap on the surface of a pneumatic bearing slightly increases and, when the current becomes higher than the saturation value, the writing magnetic field of the magnetic head becomes constant.
