Title: Square waveguide line having phase compensation slot
Inventor: ARIMURA KUNITAKA
IPC: H01Q21/06
Filed: 1987-10-08
Abstract: PURPOSE:To prevent the gain degradation due to phase difference by providing a power radiation slot concentrically onto a metallic plate forming a square waveguide space so as to radiate power of the same phase. CONSTITUTION:A couple of metallic plates 1, 2 provided oppositely apart from each other and a metal-made circumferential wall connecting the circumferential part of the metallic plates form a square waveguide space, and a feeder aperture 2a connected to a horn waveguide 3 as a feeder is provided on the metallic plate 2. Then a slot 1a is provided on the same phase line, that is, concentrically so as to apply phase compensation of a radio wave propagated from the horn waveguide 3, that is, a radio wave whose equi-phase face is distributed on the concentric circles around the feeding point. Thus, the disadvantage of production of a phase difference to a radiated power from the power radiation slot 1a resulting in decreasing the gain is avoided.

Inventor: KAWABATA SHIGEO
IPC: B21B23/00
Filed: 1984-12-05
Abstract: PURPOSE:To improve the yield of a product, etc. by detecting the wall-thickness of a steel pipe in a spiral form, Fourier-analizing the obtained data and obtaining the period of a thickness-deviation severity from the analyzed results to presume the generating cause of thickness deviation. CONSTITUTION:A wall-thickness detector 3 for detecting the wall-thickness of a steel pipe 2, a data processor 5 and an indicator 6 for indicating a period of thickness-deviation severity, are disposed. The detector 3 detects spirally the wall thickness of the moving pipe 2 while rotating plural sensors distributed in the longitudinal direction with respect to the moving pipe 2. These wall- thickness data are Fourier-analyzed by the processor 5 through a controller 4, to obtain a period of thickness-deviation severity in the longitudinal direction of pipe 2 from the analyzed data. Thus, the generating cause of wall-thickness deviation is surely seized based on the period of thickness-deviation severity. Accordingly,the quality and yield of a product are improved by taking a measure to prevent the wall-thickness deviation.

Title: Semiconductor device
Inventor: KAWAMOTO YOSHIFUMI
IPC: H01L27/08
Filed: 1984-12-06
Abstract: PURPOSE:To contrive prevention of a latch-up phenomenon caused by a parasitic bipolar transistor and a remarkable improvement in integration by introducing impurities of the same conductive type as the well on side-wall side as a channel stopper into the side wall of a groove. CONSTITUTION:A P-well 102 and N-well 103 are formed on an N type Si substrate 101 and a groove 104 of about 5mum deep and 1mum wide is formed on a boundary of the P-well and the N-well. An SiO2 film 105 of 20nm thick is formed on the surface of Si. A GiO2 film 116 and an Si3N4 film 121 except the grooves are removed to exposed the surface of the Si substrate of an active region. An SiO2 film 123 as a fate insulating film, gate electrodes 124, P type high-concentration impurity layers 125 and an N type high-concentration impurity layer 126 used as source and drain regions are formed. As a channel stopper layer 115 is formed on the side of P-well 102 on a side wall of the groove, the side wall does not reverse electrically and if a part of the element contacts with the side wall of the groove, a channel is not formed on the side wall and accordingly there is almost no leakage current which flows between the N-well 103 and the N type high-concentration impurity layer 126.

Title: Treatment of electron gun
Inventor: ITO HARUO
IPC: H01J9/14
Filed: 1986-10-28
Abstract: PURPOSE:To prevent potential fluctuation caused by current leakage by irradiating electron beams from a cathode of an electron gun to an electrostatic convergence electrode and the periphery thereof so as to eliminate the source of current leakage in the periphery of the electrostatic convergence electrode. CONSTITUTION:The irradiation of electron beams from a cathode of an electron gun 2 to the periphery of an electrostatic convergence electrode 3 causes electrons to collide with electrostatic convergence electrode plates 3c and 3d, resulting in decreased potential of the electrostatic convergence electrode plates 3c and 3d, and increased potential difference, i.e. convergence potential difference Econv, between the electrostatic convergence electrode plates 3c and 3d and high tension electrode plates 3a and 3b. The increased convergence potential difference Econv provides actual knocking effect, eliminating dusts and hurrs. At the same time, the irradiation of electron beams causes the electrostatic convergence electrode 3 and peripheral electrodes to generate heat and discharge the gas absorbed to the electrodes, and the electron collision, too, causes the gas absorbed to the electrodes to discharge, with the discharge gas absorbed to a getter.
