Title: Undulator device
Inventor: YOKOYAMA MINORU
IPC: H01S3/30
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To generate output electromagnetic waves of high quality by preventing the size of an electron beam from growing larger in an undulator. SOLUTION: Plasma areas 9 are formed in an electron beam track in a vacuum chamber 3, disposed between magnet rows and the size of an electron beam passing therethrough is reduced by the use of a converging action of the electron beam revealed by ions remaining in the plasma areas, whereby the quality of the electron beam is kept sufficiently high even at the ends of a long undulator. Accordingly, it is made possible to generate a light beam of better quality by increasing the frequency of a magnetic field.

Title: High-efficiency power amplifier
Inventor: YOKOI ATSUYA
IPC: H03F3/20
Filed: 1988-04-15
Abstract: PURPOSE:To reduce the size and weight of a power amplifier by adding a lambda/8-wavelength open stub and lambda/8-wavelength short stub to the output terminal of a lambda/4-wavelength distributed constant line. CONSTITUTION:The synthesized impedance Zp of a lambda/8-wavelength open stub 3 and lambda/8-wavelength short stub 4 is expressed by an equation. When the (n) of the equation is an even number, the numerator of the equation becomes zero and the impedance Zp becomes zero. When the (n) is an odd number, on the other hand, the denominator becomes zero and the impedance Zp becomes infinity. In other words, when the lambda/8-wavelength open stub 3 and lambda/8-wavelength short stub 4 are connected with each other, the output terminal of a lambda/4-wavelength distributed constant line 2 is set in a short-circuited state against even-order higher harmonics and in an opened state against odd-order higher harmonics. Therefore, the power loss inside the amplifier element can be reduced to a half and the operating efficiency of the amplification factor can be improved. As a result, this power amplifier can be reduced in size and weight.

CONSTITUTION:This lens consists of three elements in three groups, i.e. the 1st group lens 10 which is a positive meniscus lens having its convex surface on an object side, a 2nd group lens 12 which is a biconcave lens having a surface large in radius of curvature on the object side, and the 3rd group lens 14 which is a biconvex lens using the rotary aspherical surface as its image-side surface (right), and a stop 13 is arranged between the 2nd group and 3rd group. The 1st group 10 and 3rd group 14 are made of high-refractive index glass and the cone constant of the rotary aspherical surface of the 3rd group 14 is determined on condition that 0.0<k<3.0. When the upper limit of this condition is exceeded, the spherical aberration and astigmatism decrease, but the comatic aberration increases correspondingly. Further, when the lower limit is exceeded, on the other hand, the spherical aberration and astigmatism increase, comatic flare becomes large, and MTF decreases.

IPC: B41J2/50
Filed: 1989-04-14
Abstract: PURPOSE: To satisfactorily display all characters by dividing an element on the center column of a matrix into two parts. CONSTITUTION: A matrix display for displaying symbols such as alphabetical characters and numerals consists of picture elements forming a 5×3 matrix, and one element Pi on the center column of the matrix is divided into two parts P5a, P5b.

Filed: 1983-05-28
Abstract: PURPOSE:To prevent generation of a defective joint zone and to obtain high joint strength by forming slits having open ports opening to the side end edge of a metallic body on at least one of the joint surfaces of the metallic body to be joined. CONSTITUTION:Slits 3 are formed on a joint surface 2 in the case of joining metallic bodies 1 by a joint. The slits 3 are such linear hollow grooves having open ports 5 opening to the side edge end 4 of the bodies 1, for example to the side face A corresponding to the cut end surface in the case of, for example, a disc material at >=1 point. The joint surfaces of the metallic bodies formed with the slits 3 on at least one of the joint surfaces are placed to face each other with a solder material in-between and are joined by brazing in accordance with the conventional method. The gas between the joint surfaces is thus thoroughly expelled to the outside in the stage of brazing and is no more confined therein and therefore the joint part joined firmly to a wide joint area is obtd.

Title: Hydraulic circuit for pile driving machine
Inventor: IKUTA MASAHARU
IPC: E02D7/22
Filed: 1995-03-28
Abstract: PURPOSE: To allow a pilee to penetrate with no risk of disturbing the surrounding wall surface by connecting pipelines with the inlet and outlet for a working oil of a hydraulic motor which elevates and sinks a rotational driving device, and installing a shortcircuit valve to put the lines in communication and shut-off with each other. CONSTITUTION: To insert a steel pipe pile into a ground of an ordinary earth, a shortcircuit valve 24 is switched from the shutoff position (a) to the communication position (b) so that the inlet and outlet for a working oil of a hydraulic motor 10 are shortcircuited. The steel pipe pile is rotated through the action of a rotational driving device, and penetration is performed in the condition that the deadweights of the pile and driving device are applied to the pile, i.e., the condition the thrust force with the drive of the hydraulic motor 10 refrains from application on the pile. In case the pile is to be inserted into a soft ground, the shortcircuit valve 24 is switched from the communication position (b) to the shutoff position (a), and the rate of flow of the working oil is adjusted to a smaller side by a velocity adjusting valve 17 so that the sinking speed is suppressed.  This allows burying of the pile through utilization of its empty weight, so that penetration can be performed with no risk of disturbing the wall surface surrounding.
