Title: Antenna system shared for different polarized wave
Inventor: TAGUCHI HARUO
IPC: H01P5/16
Filed: 1987-05-13
Abstract: PURPOSE:To attain the suppression of the interference between different polarized wave signals in its own station without giving any distortion to a substantial transmission signal by using a signal from a bypass so as to cancel the quantity of interference from a polarizer. CONSTITUTION:A synthesis circuit 9 and a branch circuit 10 are inserted respectively on the way of a couple of transmission lines 3, 4 for different polarized wave signals led out of a polarizer 2. The length of a bypass 11 is selected so as to have a difference by lambda/2 (lambda is the wavelength of the signal center frequency) with respect to the length of the transmission line comprising branch circuit 10  signal transmission line 4  polarizer 2  signal transmission line 3  synthesis circuit 9. Thus, the interference from the polarizer 2 is eliminated nearly completely thereby reducing the mutual interference quantity in its own station between different polarized waves.

Title: Decompression device for ultrahigh purity gas
Inventor: HORUSUTO BAUERU
IPC: G05D16/06
Filed: 1992-05-08
Abstract: PURPOSE: To eliminate the entering of foreign matters in a gas flow coming out of a housing main body and, at the same time, to precisely control the output of a decompression device by providing permanent magnets to a slider valve for adjustment. CONSTITUTION: A high-pressure gas flows in a centai axial hole housing a slider valve 3 for adjustment through connecting branches 23 and 37 and, after the gas flows in a low-pressure space housing a diaphragm 4 from the hole through the hole of a valve seat 2, further flows to a connecting branch 24. When the pressure of the gas becomes higher than a fixed value in the branch 24, the pressure in the space housing the diaphragm 3 also rises to such an extent that the diaphragm 4 is raised against the force of a compression spring 17. The slider valve 3 follows the movement of the stopper shoulder of the valve 3 until the stopper shoulder reaches the valve seat 2 and interrupts the succeeding gas supply due to the magnetic forces of permanent magnets 5 and 6 working on the valve 3.  Therefore, the gas pressure on the output side of a decompression device is prevented from rising from a fixed value.

Title: Partially fabricated ic chip package
Inventor: KANO MICHIO
IPC: H01L23/12
Filed: 1987-05-15
Abstract: PURPOSE:To realize a high-precision finish by a method wherein a punch and a die consisting respectively of top and bottom portions are subjected to vertical vibration for a relative displacement by a desired depth for the formation of a recess for softening by local heating. CONSTITUTION:A partially fabricated IC package material 11 that is flat in geometry is supported, at portions corresponding to an outer circumference 15, between a die upper and lower portions 5 and 6 provided with holes 5' and 6' to match recesses in an IC chip. The material 11 is subjected to clamping between punch upper and lower portions 7 and 8 housed in the holes 5' and 6' and provided with pressing faces 7' and 8' in contact with a recess inner circumference 14. The punches 7 and 8 are caused to go into a vertical vibration 15 by a servo cylinder or the like that is so intensive as to cause plastic deformation only on a circumferential portion 4' of the material 11, and the heat thus generated locally softens the circumferential portion 4'. The punches 7 and 8 are caused to move by a desired recess depth, vertical vibration is stopped, and the softened portion is allowed to cool and harden. In this way, irregular surface on the shorn portion is flattened, which ensures that a high-precision microstructural circuit pattern will be completed without damage on the partially fabricated IC chip package material 11.

Title: Recording device
Inventor: KIKUTA MASAYA
IPC: B41J5/30
Filed: 1994-05-30
Abstract: PURPOSE:To effectively utilize a memory means in which data is to be stored, by dividing a plurality of recording elements in accordance with contents of recording data and not assigning the memory means when there is no recording data for the obtained element group. CONSTITUTION:For example, in first through sixth columns of a record buffer control table, ID numbers of corresponding record buffers are set. As a succeeding line space having no recording data is for 12 dots, a flag IFF without record buffer is set in a seventh column, not assigning record buffer. In a next record buffer ID7, data is set because a blank area for 4 bits corresponds to a part of a character string at a second line for 4 bits. As the size of the character string has 48 dots in the longitudinal direction, data is set in succeeding five record buffers ID8-ID12. Recording data for the remaining 4 dots is set in a record buffer ID13. For the remaining 4 bits, data is not set corresponding to 4 dots as a part of the blank area which succeeds the second line of the character string.

Patent JP-H09306237-A (JP)
Title: Conductor paste
Inventor: NISHIJIMA HIDETAKA
IPC: H01B1/00
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To set the specific resistance of a tungsten conductor paste at 10μΩcm or less when it is baked. SOLUTION: Tungsten particles for use in a conductor paste are made spherical in shape to reduce the possibility that the corners of the particles lock to one another, thereby smoothing the movement of the particles for a better packing property. Further, adjustment of the average particle diameter of the tungsten particles to 0.6μm or less as measured by SEM observing method, combined with the almost spherical particle shape, makes the packing property much higher than before, decreasing voids among the particles. Therefore, the packing ratio of the tungsten after baking can be increased to 94% or higher, and specific resistance after baking can be set to 10μΩcm or less.

Filed: 1985-05-31
Abstract: PURPOSE:To generate a stable laser beam by generating the laser beam of a semiconductor laser in evading a mode hopping point in which the optical output changes stepwise. CONSTITUTION:The output of an amplifier A1 enters one side input of a differential amplifier A2. In other input of said differential amplifier A2, the output, in which a reference voltage Es generated from a Zener diode ZD is voltage- divided by the variable resistance, is inserted as a control voltage V0. Said differential amplifier A2 controls the electric current to flow at a semiconductor laser element LD so that the output (namely, light output of semiconductor laser element LD) of the amplifier A1 can come to be equal to the control voltage V0. A Tr in the figure is a transistor for boosting the electric current. Here, since the control voltage V0 is selected by evading the mode hopping point, then, the step-shaped optical output change will not be generated from the semiconductor laser element LD, the stable laser light can be obtained.
