Title: Waveguide slot array antenna
Inventor: YAMAGUCHI YOSHITSUGU
IPC: H01Q13/22
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To relax the periodicity of an array of slots along the axis of a waveguide and to reduce a side lobe by arranging subarrays shifted along the axis of the waveguide, so that the subarrays in the axial direction of the waveguide and the wall of the waveguide between the subarrays do not lie on the same line. SOLUTION: Subarrays are arranged, while shifted along the axis of the waveguide so that the subarrays in the axial direction of the waveguide and the wall of the waveguide between the subarrays are not on the same line. This antenna inputs an electromagnetic waves from a rectangular waveguide 4 for feeding and radiates the electromagnetic waves from a radiation slot 1. Subarrays 5a to 5d of this antenna are arranged while shifted by an integral multiple of, for example, 1/2 in-tube waveform along the axis of the waveguide, and then the periodicity of the array of slots in the axial direction of a rectangular waveguide for radiation is relaxed. Since this array constitution eliminates the need for shifting the positions of a feed slot and the rectangular waveguide for feeding, a supply circuit is easily designed.

Abstract: PURPOSE: To increase an initial adhering amount of cells to the surface of a base and to multiply the cells efficiently, by bringing cells suspended in a medium having no blood serum into contact with a cultivation base, followed by adding blood serum to the medium.  
     CONSTITUTION: Cells are suspended in a medium, e.g., an Eagle's medium having no blood serum, etc. to give a cell suspension, which is brought into contact with a base in a carbon dioxide incubator maintained at about 37°C for about 0.02W10 hours, preferably about 0.1W5 hours so that the cells are fully made to adhere to the surface of the base. Blood serum(preferably that of a calf or a fetus of cattle) is added to the medium to make the concentration about 5W10wt%., or the medium is replaced by that having about 5W10wt% of blood serum and the cultivation is continued. The cells are thus efficiently multiplied and the method can be applied to a method using a plastic laboratory dish or a cultivation bottle, or a method using a semipermeable membrane.

Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a developing device which suppresses concentration decrease with time, further, suppresses density decreases at both ends part on an image, and obtains a high quality image. SOLUTION: By setting the lower end of a partition window 25 and the rotation center 22C of a stirring device 22 to the range of 0 deg.-+25 deg. to the rotation center 18C of a developer carrier 18, developer T is restricted at the lower end of the partition window 25 and, at the same time, the developer T can be carried from a stirring chamber 20 to the developer carrier 18 satisfactorily in balance. Thus, a concentration decrease with time can be suppressed, and a concentration decrease after it is left in a high temperature and humidity environment can be prevented.  Also, by setting 1.5×B>=A>B, wherein A is the width of each of the axial end parts of a resin film 36 and B is the width of the axial middle part, an amount in the carrying of the developer T is made larger at both the axial end parts than the axial middle part, and an insufficiency of the developer T near both the axial ends of the developer carrier 18 is prevented, therefore the density decreases at both the ends of the image can be prevented.

Title: High-strength, high-oil content, sintered oil-containing bearing
Inventor: OBARA KUNIO
IPC: F16C33/06
Filed: 1978-04-04
Abstract: PURPOSE: A bronze base sintered oil-containing bearing incorporates P to provide an enhanced oil content and strength.  
     CONSTITUTION: P is added in an amount of 0.2 to 1.7% by weight to a bronze base sintered oil-containing bearing containing 8 to 11 % by weight of Sn, and as required one or more of lubricant components such as molybdenum disulfide, graphite, Pb, Pb alloy, etc. Such P-containing bronze powder sintering is effective in that first, Sn and P alloying into Cu matrix is accelerated, and second, Sn solution into Cu is effectively reduced by P which is soluted together with Sn into Cu matrix. Thus, the process provides a highly tough Cu-Sn-P alloy, while increasing a relative ratio of liquid phase quantity so as to swell Cu matrix, resulting in coarse Sn flow pores and enhanced porocity (or oil content). The resultant sintered oil- containing bearing is provided with such a high oil content and strength that withstand severe operation, contributing to a long service life.
