Title: Waveguide slot antenna
Inventor: TAKEGAWA TOSHIO
IPC: H01Q13/10
Filed: 1990-06-18
Abstract: PURPOSE:To improve omni directivity by improving perpendicular plane directivity by stacking two waveguide slot antennas in a perpendicular direction. CONSTITUTION:A waveguide slot antenna unit 1 and a waveguide slot antenna unit 2 are stacked by arranging their slot planes 11 and 12 in the same direction, and a feed probe with 3/4-wave is provided by piercing through the antenna units 1 and 2. Since the feed probe 3 is of 3/4-wave, current distribution on the feed probe 3 goes to the one nearly as shown in dotted line, and an excitation phase in each antenna unit shows a negative phase as shown in arrow head. The phases of electromagnetic waves radiated from all the slots can easily be arranged equally by setting the inclining directions of slots (for example, slots 12a and 22a, or slots 11n and 22n) located at the same distance from the feed probe 3 reversely.

Title: Thin film magnetic head
Inventor: OSHIMA ISAO
IPC: G11B5/31
Filed: 1986-07-09
Abstract: PURPOSE:To control inductance of a coil conductor by providing >=3 bonding parts for external connection to the coil wiring formed at the coil conductor. CONSTITUTION:When the characteristics of head cores 3 and 4 have variation or fluctuation, the head inductances are affected and the number of turns of a main coil 5 must be changed. In such a case, the actually working number of coils are decreased as long as the transfer of signals is carried out between a bonding pad 82 led out of a middle part of the coil 5 and one of two bonding pads 80 and 81 of the coil 5. Thus the head inductance can be controlled by providing a large width part (bonding pad) 80 that can be bonded at a middle part of the coil 5.

Title: Rotary damper
Inventor: ISHII TERUTO
IPC: F16F7/04
Filed: 1987-06-29
Abstract: PURPOSE:To enable mounting of a rotary damper to an arbitrary intermediate rotation part, by a method wherein different liquid pressures classified by the direction of forward or reverse rotation of a rotor shaft are exerted on a moving vane to automatically open and close a seal part, and a seal pressure is automatically regulated. CONSTITUTION:A moving vane 7 of synthetic resin, having excellent sealing ability, is retractably disposed in a recessed part 61, and its tip part 71 is slid over the inner surface of a casing 2 to partition a liquid chamber 5. Since, with the rotor shaft 4 rotated in the direction of an arrow mark (m), liquid in a chamber 5a is compressed by a partition surface 72 and a stationary wall 9, high resistance is exerted on the vane 7, and high brake torque on the rotor shaft 4 is generated. During the damping, a part of the liquid in the chamber 5a is moved through an orifice 91 to the chamber 5b side, and enters the recessed part 61 through a bypass hole 62 to push up the vane 7, and therefore a seal force is also changed according to a change in a liquid pressure.

IPC: H01P11/00
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To suppress variation in resonance frequency by making it difficult to draw lines of electric force in by forming a recessed part at the periphery of a projection part of an internal dielectric. SOLUTION: This dielectric resonator 11 is constituted of a dielectric resonator main body 18 consisting of a frame body 13, which has a conductive layer 12 over the entire surface of its outer periphery and an internal dielectric 14 fixed integrally to the internal wall surface in the frame body 13. Here, a conductive layer may be formed on the end surface of the opening surface of the frame body 13. Further, a projection part 15 may be formed on the surface of the internal dielectric 14. A recessed part 16 is formed at the periphery of the projection part 15. The projection part 15 is formed by the remaining of a dielectric ceramic at the injection hole part of a metal mold at the time of injection molding. The dielectric resonator 11 having this structure makes the lines of electric force flow into the internal dielectric 14 hard to be drawn in by the projection part 15.  Consequently, the effect that the projection part 15 makes on the resonance frequency of the dielectric resonator 11 is relaxed.

Abstract: PROBLEM TO BE SOLVED: To form an interlayer insulating film having planar or smooth surface on a plane having protrusions and recesses by photochemical vapor phase reaction employing UV light source excitation or photochemical vapor phase reaction and plasma CVD using employing liquid reactive gas. SOLUTION: A silicon oxide coating 10 is formed by about 5000 Åon a substrate 12 having protrusions and recesses by photo assisted CVD.

Abstract: PURPOSE: To effectively remove nitrogen from waste water in simplfied operation, by removing nitrogen of nitrogen compounds, in the waste water outside the system by repetition of oxidation by aeration and reduction by maintaining the waste water under an anaerobic condition after introduction of crude waste water, in a gaseous state outside the system.  
     CONSTITUTION: In treatment of organic waste water containing nitrogen compounds which are irregularily discharged by small amount at high concentration in general, the waste water is aerated in the presence of active sludge until nitrogen in the nitrogen compounds is converted into a nitric or nitrous state. A next-day's part of crude waste water is added to at least a day's part of the nitrogen compound-cintng. organic waste water without inflow of oxygen, and the mixture being kept under an anaerobic condition is agitated. Thus, organic substances i the influent of the crude waste water are utilized as a hydrogen- donating source to reduce the nitric or nitrous nitrogen exsisting in the water. The reduced nitrogen is discharged in a gaseous state outside the system. After the reduction is continued for a certain period, the mixture is reaerated in the same way as aforementioned and let alone as such for a while. A part of supernatant is extracted. The same operation is repeated in succession.
