Patent JP-H1116775-A (JP)
Title: Capacitor array and its manufacture
Inventor: TANAKA KAZUYUKI
IPC: H01G4/38
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a capacitor array which can reduce the generation of crosstalks. SOLUTION: A sintering delay material is used in a manufacturing process, a sintering degree is made low in low-permittivity regions 21a between adjacent internal electrodes 22 in an identical internal electrode layer, fine air layers 21b are formed so as to be dotted between dielectrics, and permittivity is lowered due to the air layers 21b. In addition, in dielectric layers other than the low-permittivity regions 21a, their sintering degree is made higher than that of the low-permittivity regions 21a, no air layer exists between the dielectrics so as to become a compressed state, and high permittivity is obtained.  In a capacitor array 20 which is obtained in this manner, permittivity becomes low between the adjacent internal electrodes 22 in the identical internal electrode layer, permittivity becomes high between the adjacent internal electrodes 22 which are adjacent in a lamination direction, a desired capacitance can be obtained for every capacitor, stray capacitance between the adjacent internal electrodes 22 in the identical electrode layer is reduced, and it is possible to restrain crosstalks between different signals which are generated by the stray capacitance.

Title: Surface treatment of electric substrate
Inventor: SAWA YOSHIHIDE
IPC: B05C3/09
Filed: 1992-06-24
Abstract: PURPOSE:To simply and uniformly treat the surface of a substrate by immersing the substrate in a treatment solution and allowing the surface of the treatment solution to fall. CONSTITUTION:A substrate 3 is immersed in the treatment solution 2 of a treatment solution tank 1 for a required time and, thereafter, the treatment solution tank itself is allowed to fall at a required speed and the surface 20 of the treatment solution 2 falls with respect to the substrate 3 accompanied by the falling of the tank 1. Or, a discharge port is preliminarily provided to the bottom part of the treatment solution tank 1 and the substrate 3 is immersed in the treatment solution 2 and, thereafter, the treatment solution 2 is discharged from the discharge port to allow the surface 20 of the treatment solution to automatically fall. Since the surface 20 of the treatment solution 2 itself is allowed to fall, the non-uniformity of surface treatment can be excluded and the uniformity of characteristics due to treatment between lots and within lots is enhanced. Further, the increase of equipment for surface treatment is also suppressed.

Title: Standing wave preventing device for pipe
Inventor: ARAKAWA SATOSHI
IPC: F16L55/02
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To reduce or prevent the generation of a standing wave from a single or a plurality of pipe bodies without changing a pipe length. SOLUTION: This device is formed such that a sound absorbing layer part 2a is formed in the intermediate position of the pipe 1A of a standing wave preventing device 100a consisting of a pipe 1a where pipes 1A and 1B are juxtaposed. The sound absorbing layer part 2a is changed in a sound wave, passing through the pipe line 8 of the pipe 1B, and a wavelength form since the form of the wavelength of a sound wave passing through the pipe 1A is changed, and as a result, the resonance frequency of a wavelength does not coincide with that of a pipe length and a standing wave is not generated from a sound wave coming out from a pipe 1D. This constitution reduces the generation of noise without changing a pipe length.

Title: Pulley and fan and ball bearing of these
Inventor: SUZUKI YOSHIAKI
IPC: F16H55/36
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of abnormal sound when cold by arranging ball bearings in a single row, bringing a rolling body and outer ring of the ball bearing into contact at two points, providing an oil groove in the vicinity of a contact position with the rolling body on an outer ring track face, ensuring a function as a pulley, and taking durability into consideration. SOLUTION: When an outer ring 2a and a ball 2c of a ball bearing 2 are brought into contact each other at two points, behavior of the ball 2c, particularly its behavior in the axial direction, is suppressed, and the occurrence of abnormal sound when cold due to self-energizing vibration of the ball 2c is suppressed effectively. Moreover, even when load is concentrated at a contact point on one side due to vibration of a belt and a contact point on the other side causes heat due to slide friction, grease sputtered from an oil groove 5 on inside diameter side due to centrifugal force is replenished at the contact point to provide lubrication action so that running out of an oil film at the contact point is prevented and good lubrication condition is maintained.  Furthermore, since a certain amount of grease is held in the oil groove 5 even after operation is stopped, a uniform oil film is formed on an outer ring track face 3a at the time of restart.

IPC: H01P1/22
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To obtain attenuation with a small device by arranging an inserted element and a vertical direction groove at the same height as an elbow formed by a waveguide and increasing the waveguie which is surrounded by straight lines in proportion to the inserted element introduced to the inside of the waveguide. SOLUTION: A variable attenuation device for a rectangular waveguide is provided. It essentially contains a round form which is designed so as to be introduced vertically to the inside of a waveguide 3 by piercing through a planar inserted element 5 and a vertical groove 7 formed along the transmission shaft of the first intrasurface wave of the waveguide. The inserted element 5 turns around a shaft 6 deviated from the center and can move. Thus, the part of the inserted element which is introduced to the inside of the waveguide in this way is a function of the angular position of the inserted element. For increasing the part of the inserted element which is introduced to the inside of the waveguide, the inserted element 5 and the groove 7 in the vertical direction are arranged at the height of an elbow formed by the waveguide.

Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain the sensitivity of a horizontally polarized wave component of a circularly polarized wave at a low elevation angel by arranging plural planar radiating elements under the ground conductor plate of a microstrip planar antenna (MSA) and electrically connecting them to the ground conductor plate. SOLUTION: In an MSA1, a circular patch-shaped radiating element 1b is attached to a circular dielectric substrate 1c. A ground conductor plate 1d is supported by a dielectric cylinder 4, with almost the same diameter and four pieces of planar radiating elements 3, are attached to all around the cylinder 4 with intervals respectively. The plane where the elements 3 are distributed and arranged exists on the circumference with almost the same diameter as the MSA 1. The plate 1d and each element 3 are electrically connected with a wire 2. The plate 1d is a common ground conductor for the MSA 1 and the elements 3.  The sensitivity of a horizontally polarized wave component at the low elevation angle of the MSA 1 is improved by the operation of high frequency current which flows along the lateral direction of the elements 3 and the sensitivity of a vertically polarized wave component is improved by the operation of high frequency current flowing along the vertical direction.
