Title: Rarticle sensor
Inventor: BURAIAN JII MATSUKUGII
IPC: G01N15/06
Filed: 1992-05-20
Abstract: PURPOSE: To effectively detect metal particles in fluid by sensing an electric resistance between contact electrodes and generating a signal indicating the presence of the conductive particle in response to the resistance. CONSTITUTION: A magnet 208 has second poles 210, 212. A first electrode 214 has a first contact surface 218, and is disposed adjacent to the pole 210. A second electrode 216 has a second contact surface 220, and is disposed adjacent to the pole 212. A ferrous electrode becomes a magnet by itself by the influence of a permanent magnet 208. Ferrous particles are attached to the electrodes 214, 216. The particles are captured to the bottom of a recess, and allowance for larger particles is retained at a vertex. The gap between the electrodes 214 and 216 becomes small at the bottom. Smaller particles are attracted toward the bottom, and the change of the resistance value immediately occurs. Sensing means 224 senses the electric resistance between the electrodes 214 and 216, and generates a signal indicating the presence of the conductive particles in response to the resistance.

Title: Method and apparatus for forming thin membrane
Inventor: ONO RIICHI
IPC: B05C1/02
Filed: 1986-06-02
Abstract: PURPOSE:To make mass productivity excellent and to obtain a highly accurate pattern, by forming a uniform film of a membrane forming solution on an ink roll of which the surface is ground smoothly and transferring the same to a substrate in a desired pattern through a rubber letterpress having a predetermined pattern. CONSTITUTION:Because a membrane forming solution 3 is directly transferred to a substrate 15 from an ink roll 16 through a rubber or resin letterpress 2, a conventional coating device such as a surface plate, a form surface plate or a roll coater is not required. Further, a uniform membrane is obtained only by adjusting the gap between a doctor roll 10 and the ink roll 16, the stepping pressure of the rubber or resin letterpress to the ink roll and the printing pressure to the above-mentioned letterpress. Furthermore, by supplying the membrane forming solution at a difinite interval and always rotating the doctor roll and the ink roll, the new film of the membrane forming solution is always formed on the ink roll and the membrane can be formed with high repeated accuracy.

Title: Supercharging pressure control device for engine equipped with supercharger
Inventor: TADOKORO ASAO
IPC: F02B37/12
Filed: 1980-09-17
Abstract: PURPOSE: To achieve sufficient effciency and to prevent heat deterioration of parts such as a catalyzer in an exhaust system by providing a control device which reduces supercharged pressure in response to the output of an exhaust gas temperature sensor. When the exhaust gas temperature is higher than the predetermined value.  
     CONSTITUTION: A controller 14 is provided, together with a comparator 14a, a set voltage generator 14b and an electromagnetic valve driving circuit 14c, which make response to the output of exhaust gas temperature sensor 12 to reduce the supercharged pressure when the exhaust gas temperature is higher than the predetermined temperature. The output from a temperature sensor 12 is led to the comparator circuit 14a in form of a voltage signal A in proportion to the exhaust gas temperature. Hereupon, since the set voltage takes the form of a constant voltage B, the comparator 14a compairs the voltage A with the voltage B and the output voltage C is generated when the signal A is higher than the signal B. Then, this output is fed into the circuit 14c, where the electromagnetic valve driving voltage D is generated, an electromagnetic valve 11 is opened, then a part of exhaust is led to by-pass 10. Consequently, the supercharged pressure is lowered from the condition represented by a straight line E to that by F, because the driving power of a supercharger 8 is lowered.

IPC: H01F7/20
Filed: 1983-07-14
Abstract: PURPOSE:To minimize magnetic field components unnecessary for correcting an unequal magnetic field by mounting another linear current path in parallel with a linear current path of a saddle-shaped coil constituting a correcting coil and flowing currents so that magnetic fields generated from both current paths cancel each other out. CONSTITUTION:A ZX shim coil 6 is constituted by each one pair of first and second saddle-shaped coils 7a, 7b arranged on straight lines while holding a high uniform magnetic field region 3, and each one pair of saddle-shaped coils 7a, 7b are disposed symmetrically to ZX surfaces. The ampere-turns of four saddle-shaped coils as the first and second saddle-shaped coils 7a, 7b are mutual equal. The directions of currents are determined so that the direction of the currents of the ZX shim coil and the directions of arcuate section currents on the sides near to the high uniform magnetic field region 3 of the saddle-shaped coils 7a, 7b are equalized. Arcuate sections on the sides near to the high uniform magnetic field region 3 of the saddle-shaped coils 7a, 7b may be arranged at the same position as the arcuate section of the ZX shim coil. It is preferable that the linear sections of the saddle-shaped coils 7a, 7b may be lengthened as much as possible, but short linear sections are sufficient enough when magnetic field correction outputs may be of small value.

Title: Corrugated horn
Inventor: MIYATANI SATOSHI
IPC: H01Q13/02
Filed: 1988-05-26
Abstract: PURPOSE:To remove deterioration in VSWR characteristics which are excellent over a wide frequency range by loading annular projections on conductor fins in different directions. CONSTITUTION:The axis of a circular waveguide is regarded as a Z axis and the direction from the circular waveguide 1 to the opening part of the corrugate horn 2 is defined as a plus direction. The depth of corrugate grooves 4 is almost lambda/2 (lambda: free wavelength) where they contact the circular waveguide, and varies slowly from lambda/2 to lambda/4 in the +Z direction and reaches the opening part. Starting three fins 3a-3c when the opening part is viewed from the circular waveguide have annular projections 5 loaded in the -Z direction, but a next fin 3d is inverted to the +Z direction, and a 6th fin 3f is inverted again to the -Z direction. Thus, the loading directions of the annular projections 5 are selected properly to maintain the VSWR characteristics excellently over the wide frequency range, thereby removing the deterioration in the VSWR characteristics due to reflection in some frequency band.
