Title: Ink jet head
Inventor: HIGASHIMURA KOICHI
IPC: B41J2/055
Filed: 1988-04-30
Abstract: PURPOSE:To secure accurately the size of a gap between a pressure-generating member and a nozzle irrespectively of dispersions of warpage of member, by determining the position of the pressure-generating member through the contact thereof with a displacement-restricting member. CONSTITUTION:A nozzle-forming substrate 11 is provided with a plurality of nozzles 12. Pressure-generating members 15 each of which comprises a laminate of a piezoelectric element 13 and a metallic plate 14 are disposed opposite to the substrate 11, in press contact with one side of a displacement-restricting member 16, and are immersed in an ink 17. With a voltage 18 impressed on the piezoelectric element 13, the element 13 is contracted, and by a bimetallic effect of the combination of the element 13 and the plate 14, the pressure-generating member 15 is deformed toward the nozzle 12 until it make contact with the other side of the displacement-restricting member 16. As a result, the pressure of the ink in a gap between the member 15 and the nozzle 12 is raised, and an ink droplet is ejected from the nozzle. Because deformation ranges of the pressure-generating elements 15 are equalized with high accuracy by the displacement-restricting member 16, the sizes of the gaps between the members 15 and the nozzles are also equalized with high accuracy, and there is little dispersion of characteristics between the nozzles.

IPC: H04N1/41
Filed: 1995-05-02
Abstract: PURPOSE:To reduce the storage capacity of reference tables without reducing the decoding speed of a variable length code by making a code length reference table independent of a code value reference table. CONSTITUTION:An n-bit input stream is given to a code value reference table 3. The table 3 gives a value obtained by decoding the variable length code included in the n-bit input stream. n-j bits of the n-bit input stream are given to a code length reference table 2. The table 2 is used to determine the code length of the variable length code included in the n-bit input stream. When operation is performed, n-j most significant bits are given to the code length reference table 2. The code length reference table separated from the code value reference table is used to reduce the whole of the memory capacity required for decoding of the variable length code.

Title: Optical fiber sensor
Inventor: NOGUCHI MASANORI
IPC: G01P5/01
Filed: 1982-06-25
Abstract: PURPOSE:To heighten the detection sensitivity of mechanical vibration by utilizing that the speckle pattern formed on an image sensor varies by a slight force as applied to a multi-mode optical fiber. CONSTITUTION:In a sensor section SE for detecting a mechanical vibration, an eddy generating body 2 is given a mechanical force with von Karman's vortex street formed corresponding to flow velocity of a fluid to be measured to apply a force to a multi-mode optical fiber 3. An optical signal from a light source 1 is introduced to the multi-mode optical fiber 3 within the eddy generating body 2 through an optical fiber 31. Light from the eddy generating body 2 is irradiated on an image sensor 4 through an optical fiber 32 to form a speckle pattern SP. The speckle pattern SP does not vary in itself as long as there is no change in the force to be applied to the eddy generating body 2. But any change in the force causes a change in the force of the fiber 3 whereby the pattern SP itself varies and moves.
