Title: Thermal engine
Inventor: WAKAO NORIAKI
IPC: F01L33/00
Filed: 1986-05-10
Abstract: PURPOSE:To reduce the number of valve and to simplify a mechanism for opening/closing the valve, in a pressure-mechanical converter for converting the pressure of working fluid into mechanical motion, by coupling a plurality of valve mechanisms through respective conduit sections to flow-in and flow-out ports of cylinder. CONSTITUTION:When respective conduit members 5, 5' are opened, working fluid heated by means of a boiler is fed through a flow path hole 2 of a valve mechanism 7 and the conduit member 5 into a cylinder 8. Consequently, the pressure is increased above a piston 9 so as to push down the piston 9. When the piston 9 lowers to a predetermined position, respective conduit members 6, 6' are opened and the working fluid is fed through the flow path hole 2 of the valve mechanism 7 and the conduit member 6 to the lower section of the cylinder 8 so as to increase the pressure below the piston 9. Consequently, the working fluid above the piston 9 is discharged from the cylinder 8 so as to push up the piston 9 and reciprocate in the cylinder 8.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To form an image showing superiority in terms of water resistance, light-fastness, glossiness, color development properties and the like by using an ink composition containing a colorant and a cationic water-soluble polymer expressed by a specific formula and further, using a recording medium containing a monovalent metallic salt near the surface of the ink composition. SOLUTION: An ink composition containing at least water, an alkali soluble colorant and a cationic water-soluble polymer (R1, R2 are each a 1-5C alkyl group; R3 is a hydrogen atom or a 1-5C alkyl group; and n is 0, 1 or 2) containing a repeating unit (a) and a repeating unit (b) represented by the formula, is used. Besides, a recording medium containing a univalent metallic salt near the surface of the ink composition is used to perform ink jet recording. The presence content of the colorant can be properly decided but the addition of 0.5-20 wt.% for the total weight of the ink composition is preferable. Thus a print image of sufficient optical density can be formed within the range of 0.5-20 wt.%.

Filed: 1988-04-28
Abstract: PURPOSE:To compress picture data at a high compressing ratio without deteriorating the picture quality by calculating and coding the mean value of orthogonally transforming data at every block of a low-frequency area and performing run-length coding on a high-frequency area after disintegrating the area into bit planes. CONSTITUTION:Picture data are orthogonally transformed into a spatial frequency system of 16X16 and DCT coefficients are found. Then the hatched area of the area pattern having the largest sum total value is selected as a low-frequency area and the rest is selected as a high-frequency area. Then a bit distribution calculation circuit 16 calculates the number of bits to be assigned to each block based on the mean value of the DCT coefficients thus found at every block. The quantization and coding of the high-frequency component are performed in such a way that the high-frequency component is quantized at a 2<m> level and one bit is used for code the DCT coefficients, with the (m-1) bits being assigned to the DCT coefficients. The information of the low- and high-frequency components thus found is stored in a recording and reproducing device 19.

IPC: G01D5/34
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent a light from scattering and stabilize an encoder signal, by filling the space between a pedestal and a pedestal for an optical fiber with liquid, and eliminating air bubbles in the liquid by using an air bubble extracting means. SOLUTION: Air bubbles mixed in liquid by liquid injection concentrate in an air bubble extracting means 10 by leaving the liquid for a specified period after filling. Until the liquid is discharged from the air bubble extracting means 10, the liquid is continuously supplied. In this process, the concentrated air- bubbles are eliminated to the outside. When specified filling operation is ended, the air bubbles in the liquid are completely eliminated, and air bubbles do not exist in the liquid between an optical fiber 11 and a rotary code plate 4. Thereby a light outputted from the optical fiber 11 is reflected by the rotary code plate 4 through the liquid, and sent to a control equipment or the like, as an encoder signal.

Title: Optical waveguide type long wavelength light cut-off filter and optical wavelength demultiplexing circuit
Inventor: SUZUKI YASUHIRO
IPC: G02B6/12
Filed: 1995-04-28
Abstract: PURPOSE: To make it possible to enhance working accuracy and further to control the change in characteristics by vibration and heat from outside by forming a curved optical waveguide on a substrate. CONSTITUTION: Straight waveguide parts 12 and the bent waveguide 13 of the curved state having a radius R of curvature are formed on a waveguide substrate 11. The waveguide 13 is connected to optical fibers 15 via filter junctures 14. The characteristics of the filter have substantially no loss by curving with light of wavelengths of a 1.3μm band but the loss increases as the wavelength is longer. The loss of >=20dβ is resulted with the light of the 1.5μm band. Such characteristics are indicative of the fact that the parts function sufficiently as a long wavelength light cut-off filter. Since the filter is extremely simple in structure, the number and size of the parts are reduced. Since the filter is formed on the substrate, the filter is adequate for enhancement of the performance, is excellent in mass productivity and is economical.

Abstract: PURPOSE:To obtain a high quality and high reliability image display device without fluctuation of brightness by providing comb type dampers at the position being parallel and opposed to the line cathode in the vicinity of support base of line cathode under the condition of providing a certain clearance to the line cathode. CONSTITUTION:When a pulse voltage is applied to a line cathode 11 to emit the hot electrons, a current flows for a very short period. The line cathode 11 expands thermally and resonates when the natural frequency of line cathode 11 changes and becomes almost equal to the period of pulse. A pair of metal of ceramic comb type dampers 13 are provided at the position being parallel and opposed to the line cathode in the vicinity of support base under the condition of providing a certain alearance to the line cathode. Thereby, vibration energy of line cathode 11 can be converted to friction energy. As a result, vibration amplitude of line cathode which has been + or -20-200mum in maximum under the resonant condition can be reduced to + or -20mum or less even in maximum. Accordingly, a high quality picture without fluctuation of brightness can be obtained.

IPC: E02D15/06
Filed: 1991-05-13
Abstract: PURPOSE:To obtain an executing method for cast-in-place concrete pile applied to a bearing pile or the like for the foundation of a building. CONSTITUTION:A reinforcement cage is inserted into a pile hole excavated in the ground, and concrete is deposited there. The feeding of the concrete is once stopped at a stage where an unit quantity of the concrete 3 has been deposited through a concrete depositing tremie pipe 22, and compressive force is given to the top of the deposited concrete 3 by a pressurizing device 8 set at the tip of the tremie pipe 22 to pressedly tighten the concrete. After that, the feeding of the concrete is resumed to deposit the unit quantity of the concrete, and these processes are then alternately repeated to complete the construction of the pile body. Thus pressure tightening effect is sufficiently displayed at the every depositing of the unit quantity of the concrete to improve the quality of the pile body concrete 3 and to increase its strength. The concrete 3 is well spreaded into every corner even when an impermeable film having grown on the wall surface of the excavated hole exists. thus adhesion between the ground 1 and the concrete 3 can be improved, and frictional resistance on the periphery of the pile thereby grows stronger to wholly strengthen pile bearing force.
