Title: Broad band amplifier circuit
Inventor: ANAI KIMIO
IPC: H03F1/30
Filed: 1987-03-30
Abstract: PURPOSE:To suppress the deterioration of the frequency characteristic comprising a resistor and the parasitic capacitance of a transistor (TR) by forming a feedback loop across the resistor in the inside of a DC level shift circuit. CONSTITUTION:The DC level shift circuit 30 consists of TRs 3a-3e, a resistor 10, a TR 11, resistors 12, 3f, and a bias section 13. That is, in the DC level shift circuit 30, a loop decreasing the deterioration in the frequency characteristic due to the parasitic capacitance is formed by a path of a 2nd TR 3c, a shift circuit, and a base and a collector of a 3rd TR 3b so as to improve the frequency characteristic of the base of the TR 3a. Thus, even when a resistor is used for the DC level shift circuit, the frequency characteristic is not deteriorated.

Abstract: PURPOSE:To measure temps. with high accuracy without receiving any electromagnetical influence from the outside by detecting the interference of the rays past a temp. detecting optical fiber and a by-passing optical fiber on account of the thermal expansion or shrinkage of the temp. detecting part. CONSTITUTION:The light from a variable wavelength light source 1 is fed through an optical fiber 2 to a temp. detector 3, and the light fed to the detector 3 advances dividedly and separately through a temp. detecting optical fiber 4 and a by-passing optical fiber 5, after which these are joined, and the joined light is fed through the fiber 2 to a photodetector 8. The temp. detecting part 4a of the fiber 4 expands or contracts when it is heated or cooled to the same temp. as the temp. to be measured and therefore a difference in optical path lengths is produced between the same and the fiber 5. In accordance with this difference in the optical path lengths, the joined light interferes on account of a phase difference and therefore the photodetector 8 feeds the signal corresponding to the quantity of the interference light to a controlling circuit 9. The circuit 9 determines the coefft. of expansion of the fiber 4 from the signals of the photodetector 8 and the light source 1 and displays the same as a temp. measured value in a display device 10.

Abstract: PURPOSE:To effectively start and smoothly raise the rotating speed of a motor by increasing a control voltage upon lapsing of a time and varying an increasing gradient in a plurality of stages. CONSTITUTION:When a power source switch is closed, a relay coil X is energized.

IPC: C08F2/18
Filed: 1979-06-15
Abstract: PURPOSE: To prepare a vinyl polymer, in a desired form, having a narrow range of particle size distribution, by starting polymerization after the application of a high speed shearing force to a polymerization system, which contains a portion of a vinyl monomer, and by adding the balance of the monomer when a specified degree of polymerization is attained.  
     CONSTITUTION: Water, containing a dispersing agent, a 5C or higher oil-soluble polymerization initiator and 40W90%, based on the total amount to be charged, of a vinyl monomer, are poured into a preliminary agitation vessel, in which they are preliminarily dispersed by mild agitation, and the vinyl monomer is dispersed into a minute droplet of 0.5W70μ, by the application of a high-speed shearing force of the order of 10 5 W10 6 min -1 . Then polymerization is started at 5W80°C, after the dispersion is transferred into a polymerizer, and when the perliminarily charged monomer is polymerized to an extent of polymerization degree 30W50%, the balance of the monomer is added, continuously, separately in a plurality of times, or at once, to accomplish polymerization. Thus a spherical vinyl polymer, having uniform particle size of 2W70μ, is obtained.

Title: Multi-way valve
Inventor: GIYUNTAA HIRUMAA
IPC: F15B13/042
Filed: 1990-03-24
Abstract: PURPOSE: To simplify the structure and reduce the risk of failure by introducing such a configuration that a valve rod in a first control chamber is given a section area greater than that of a piston confronting and that the force of motion toward the piston is greater than the force acting from a third control chamber to the piston. CONSTITUTION: Pilot valves 34 and 38 are formed as decompression valve of stepless operation type, and control chambers 17 and 19 receive alternately different control pressures according to the selection. A pressure is applied to a working space 5 for reducing the load, and also to a working space 6 for raising the load, when the control pressure is smaller than the max. control pressure by a pump 35 while the effective area of a piston 12 is greater than that of a confronting piston 30. When the load of the space 5 lowers, the valve 34 is actuated, and the operating pressure of a lever 40 which the control chamber 17 receives remains only a partial pressure of the max. control pressure.  Because the force applied to a control chamber 46 and a compression spring 48 for the piston 30 is greater than the pressure applied from the piston 12 to the one 30, it serves as a receptacle table for a spring holder 24.
