Title: Measuring method for precision of inner surface of through hole and manufacture of base using it
Inventor: KONDO YOSHIMASA
IPC: G06T7/00
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a precision measuring method for the inner surfaces of through holes which evaluates the precision of the inner surface of a through hole of a structure having a through hole such as an extruded base, with a high precision and quantitatively. SOLUTION: Scattered lights are emitted to a structure 1 having a through hole using a scattering board 2, and a picture image is obtained by light having passed through the inside of a through hole of a structure 1 using a telecentric optical system 3. And the picture image is analyzed by picture processing technique. Consequently, the precision of the inner surface of the through hole is measured. It is favorable that the structure 1 having a through hole may be a molding base to be used on the occasion of extruding a honeycomb substance, and that the precision of the inner surface of the through hole may be the surface roughness of the inner surface.

Title: Traveling carriage guide rail
Inventor: OIDE KOSUKE
IPC: E01B11/06
Filed: 1994-12-05
Abstract: PURPOSE: To facilitate the offset adjustment at a jointed part of a guide rail by joining both ends of a section steel guide which is adjacent with a section steel with a splice plate and cutting by a specified length from both ends of the shape steel guide so as to form a notched groove. CONSTITUTION: The length of a notched groove 27 is set within a range where no deflection of an upper flange 21 matters. An error of an adjacent shape steel guide is corrected with a splice plate 24 based on the action of the notched groove 27. An offset portion produced by the bending of a guide end at a jointed part is reduced to substantially zero. The length of the notched groove 27 is set to a specified value and the deflection of the upper flange produced by a vertical load of the upper flange 21 is adapted to be reduced to such a slight value that it may be ignored, thereby preventing the occurrence of a vertical offset on the top of the upper flange 21 with supports wheels 11.  Furthermore, even after the splice plate 24 produces a bending on a guide end face, an adjacent shape steel guide 22 is maintained on the top and the bottom of the shape steel and a guide roller 12 is installed on the guide 22 to be guided so that no error may be produced between both ends of the jointed part in the traveling direction on both sides.

Title: Adaptive array antenna
Inventor: YOSHIDA MAMORU
IPC: H01Q3/26
Filed: 1994-12-07
Abstract: PURPOSE: To attain a stable electronic tracking even when a very weak radio wave is received. CONSTITUTION: A signal received by an antenna unit 7 and frequency-converted by a 1st frequency converter 8 is given to a mixer 9-1, in which the signal is converted with a 2nd local oscillation signal generated from a high precision PLL oscillator 9-2 being a 2nd local oscillator into a 2nd intermediate frequency signal. The 2nd reference intermediate frequency signal is distributed into two by a distributer 10 via a BPF 9-3 and fed to mixers 3-3, 6-3, where phases are compared. Thus, the frequency and the phase of the 2nd intermediate frequency signal outputted from the mixers 3-1, 6-1 and those of the reference 2nd intermediate frequency signal are made coincident with each other. Thus, the signals are synthesized in phase at a synthesizer 1 to attain stable electronic tracking.

Title: Reduced-pressure coating apparatus with divided lid
Inventor: MORIOKA MASAYUKI
IPC: B05C3/10
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a reduced-pressure coating apparatus which can uniformly coat an object to be coated without causing uneven coating at the front and rear ends of the object by installing a divided lid which opens when the front end of the object contacts an outlet opening having an inclination crossing with the direction of advancement of the object and closes when the rear end passes through the opening.

Title: Chips resistor
Inventor: IWAO HIDEMI
IPC: H01C7/00
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To enhance high frequency characteristics by reducing generation of a magnetic flux effectively regardless of the number of turns at a spiral section. SOLUTION: A generated flux ≃ is passed positively through a short ring part SC formed on a resistive conductor 2 by exposing the opposite end faces 1a of an insulated chip 1 to the outside thus generating a circulation current for offsetting the flux at the short ring part SC. Consequently, generation of the flux can be reduced. Furthermore, since terminal electrodes 3, 4 having lower resistivity than the resistive conductor 2 are employed as the short ring parts SC, circulation current can be generated efficiently as compared with a case where the short ring part SC is formed on the resistive conductor 2 itself. According to the structure, the flux ≃ can be offset effectively by the circulation current.
