Title: Color difference signal double speed conversion circuit
Inventor: SAKASHITA HIROHIKO
IPC: H04N9/64
Filed: 1990-03-28
Abstract: PURPOSE:To prevent color slurring by reading a 4-bit time division color difference signal twice at a readout speed twice a write speed for one horizontal period, inputting the result to a delay circuit, detecting a timing pulse included in a vertical synchronization portion of the color difference signal, generating a control signal and inserting it to the vertical synchronization portion. CONSTITUTION:A 4-bit time division color difference signal is stored in a memory 2 for one horizontal period, read twice at a readout speed twice the write speed for one horizontal period, inputted to 1st and 2nd delay circuits 3, 4, in which the signal is delayed by one clock. Then the output of a double speed conversion circuit 1 and the output of the 2nd delay circuit 4 are inputted to a multiplexer 5, 1st H and 4th H of a control signal select the output of the double speed conversion circuit 1 and 2nd H and 3rd H of the control signal select the output of the 2nd delay circuit 4. Moreover, the 4-bit time division color difference signal is inputted to a timing generator 6 to detect a timing pulse included in the vertical synchronization portion and to generate a control signal controlling the multiplexer 5 and it is inserted to the vertical synchronization portion.

Title: Optical mode mixer
Inventor: SANO KOUICHI
IPC: G02B6/28
Filed: 1980-06-12
Abstract: PURPOSE:To mix optical modes efficiently with simple and samll-sized construction by using a glass bar having random refractive index fluctuations internally. CONSTITUTION:The light which is made incident to a glass bar 5 having random refractive index fluctuations internally from an incident optical fiber 3 is bent randomly by Snell's law and emits at the angle differing from the incident angle at the output part of the glass bar. Since the angle of propagation in general corresponds to the numbers of the modes of the light propagating in a fiber, the change in this angle signifies mode conversion and this turns out that the light has received mode conversion in the glass bar. Further, the pass of beams of light takes random loci and therefore the optical path length varies with each incident mode and the phasss thereof are random as well. This glass bar is made by applying thermal strains to multicomponent type glass.

Abstract: PURPOSE:To contrive drastic reduction of NOx by keeping stabilized thin combustion on, by a method wherein while a jet making a part of an air-fuel mixture blow off into a combustion chamber through the inside of a flame holding core is being formed, an air hole supplying air from the outside of a mixing chamber further to a flow of the other air-fuel mixture running along the external circumference of the flame holding core is provided. CONSTITUTION:Fuel F is sprayed from a fuel injection valve 17 to air A flowing in a mixing chamber 16 from an upper air hole 18 of a mixing pipe 15 and comparatively thick air-fuel mixture is produced. It becomes that a part (assistant air-fuel mixture M') of the air-fuel mixture passes through the inside 23 of a flame holding core 20 and blown off into a combustion chamber 13 from a jet 24 of a bottom wall 21. On the one hand, although the remaining air- fuel mixture (main air-fuel mixture M) flows in the combustion chamber 13 through a turning blade 19 along the external circumference of a cylindrical part 22 of the flame holding core 20, air B is supplied further to the flow from an air hole 25 of a circumferential wall of the mixing pipe 15 and flows in the combustion chamber 13 while it is being diluted. With this construction, along with formation of a large scale circulation region on a rear flow of the flame holding core 20, the comparatively thick air-fuel mixture M' can be supplied within the circulation region and favorable combustion reaction can be kept within the circulation region by the air-fuel mixture M'.

Title: Swash plate type piston pump and motor with variable capacity
Inventor: HIROOKA YASUO
IPC: F04B1/07
Filed: 1989-03-29
Abstract: PURPOSE:To construct an axial piston and motor in small size and light in weights and provide it with good maneuverability by locating the axis of swash plate tilting nearer the swash plate than the plane in which the spherical center of the piston tip lies, inclining the piston axis relative to the axis of a drive shaft, and allowing the mean acting line of the piston resultant force to pass the intersection of the axis of drive shaft with the axis of tilting or in the neighborhood thereof when the swash plate is tilted to its maximum. CONSTITUTION:The swash plate tilt axis 14 is located nearer the swash plate 3 than the plane 17 in which the spherical center 16 at the tip of a piston 4 of a cylinder block 2 lies. Accordingly the part of fixing the swash plate tilting shaft protrudes a little from the piston guide surface, or does not protrude at all, so that the width of the swash plate drive shaft 11 in the axial direction is lessened to allow the swash plate 3 to be constructed in small size and light in weight. Further the mean acting line (n) of the piston resultant force when the swash plate tilts to its maximum, is so arranged as to pass the intersection of the drive shaft axis 11 with the swash plate tilt axis 14 or in the neighborhood thereof, so that no moment will be generated which might interfere with the swash plate motion, that will enhance the maneuverability for the swash plate 3.
