Title: Manufacture of whisker preform for composite material
Inventor: YASUNAKA TOMIYA
IPC: B22D19/14
Filed: 1984-12-21
Abstract: PURPOSE:To obtain the titled preform provided with homogeneous, honeycomb, and porous structure by emulsifying whiskers with water, a hydrophobic org. solvent, and an emulsifier, filtering the obtained emulsion, and drying the formed whisker cake. CONSTITUTION:The raw material of whiskers is charged into water, agitated, and uniformly dispersed by using a mixer such as a spiral flow agitating vessel. A hydrophobic org. solvent is added along with an emulsifier into the water wherein whiskers are dispersed, and the mixture is rapidly agitated to form an emulsion. In the emulsion thus formed, the outer surfaces of the innumerable floating spherical colloidal particles of the hydrophobic solvent are covered with groups of whiskers having good affinity for water and present in the water. The emulsion is charged into a filter, and filtered. The wet whisker cake formed by the filtration or the cake after being impressed is regulated to obtain a specified volume density and then the cake is dried to obtain a whisker preform.

IPC: F16F1/10
Filed: 1992-10-07
Abstract: PURPOSE:To provide a spring without the dispersion of a spring constant by cutting the spring spirally out of a plate, cut out at two faces parallel to the specific crystal face of monocrystal material, using an exposure means and an electron beam image describing means. CONSTITUTION:Monocrystal silicon is cut into the fixed thickness, to the specific crystal orientation to obtain a silicon wafer 10. Photo-resist 11 is applied to the surface of the silicon wafer 10, and a photomask 12 of spiral spring pattern is applied to the surface. The photo-resist 11 is sensitized being exposed to light, X-rays, or the like, and the photo-resist 11 at the sensitized part is developed and removed. The silicon at the part rid of the photo-resist 11 is then removed by etching, and a spiral spring is cut out of the silicon wafer 10. The remaining photo-resist 11 is separated and removed. The atomic arrangement structure of the material is constant, and a constant Young's modulus can be obtained, so that the spiral spring can be manufactured precisely. Constant braking torque can be also obtained so as to enable the realization of an electric indicating instrument of high accuracy.

Filed: 1986-11-13
Abstract: PURPOSE:To display a usable time with high precision even if the thickness of a transfer sheet is changed and to improve controllability, by providing a means, computing a remaining continuous usable time from various data, and a display part for the computing means. CONSTITUTION:When a tray 35 is raised through drive of a feed motor 36, a filter 46 mounted to the under surface of the tray passes a lower limit sensor 47. From that point of time, pulses from a remaining amount sensor 39 are started to count, a transfer sheet 34 pushes up a feed roller 48, and the number of pulses accumulated until it is detected by means of an upper limit sensor 49 is counted. Since a moving distance of the tray 35 is changed according to an amount of the transfer sheets 34, the number of pulses is also changed to detect a remaining amount of the transfer sheet. After the edge of a pulse from the remaining amount sensor 39 is detected, the number of the fed transfer sheets 34 is started to count, and the counting is continued until the edge of a subsequent pulse. When the resultant value exceeds a given value, it is decided that the thickness of the sheet is changed, an average of values on and after the change is set to a transfer sheet per one pulse, and a usable time is calculated.

The end face 10a on the right side of the waveguide element 10 where the pitch conversion is not required is connected directly with the fiber array 11. The waveguide pitch widened on the right side of the pitch conversion part of the waveguide element 12 is made coincident with the core intervals on the connecting side of the fiber array 13.  On the other hand, the right side waveguide pitch of the waveguide element 10 where only the optical circuits alone are integrated suffices with the intervals of the extent that the light propagating in the waveguides adjacent to each other do not interfere.

Title: Ion planting apparatus
Inventor: KINDAICHI YOUZOU
IPC: C23C14/32
Filed: 1991-10-17
Abstract: PURPOSE:To provide an ion plating apparatus capable of accelerating an evaporated and ionized material toward a substrate and allowing the material to collide against the substrate even in the case of an insulating substrate or even in the case where an insulating material is allowed to adhere to a substrate. CONSTITUTION:A material 2 in a crucible 3 is irradiated with the electron beam from an electron gun 4, by which the material is heated and evaporated. The evaporated material is ionized by means of electric discharge due to the RF electric field caused by the high frequency waves impressed to an RF discharge electrode 5. Positive voltage and negative voltage are alternately impressed to a substrate 8 by the impression of high frequency waves. When the positive voltage is impressed on the substrate, electrons are attracted by the substrate 8. In the case where the substrate 8 is composed of insulating material, the surface of the substrate is negatively electrostatically charged by the electron collision. Further, when a negative voltage is impressed on the substrate 8, the potential of the surface of the substrate 8 is kept negative by the impression of the negative voltage combined with the above negative electrostatic charge due to electron collision. As a result, the evaporated and ionized material is accelerated toward the substrate 8, by which the material having high energy can be allowed to adhere to the substrate.

Title: Front control device for swing type hydraulic shovel
Inventor: NASU KATSUYOSHI
IPC: E02F9/22
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To again return the working front to the initial direction by a simple operation even if the direction of the working front is changed by providing a control means for the working front to be stopped in a designated direction when the start of directional control is designated by a first switch means. SOLUTION: The direction of a working front is aligned with the excavating direction, and a setting switch 24 is pressed. Whereupon, the direction of the working front is set, and the working front is operated to excavate a ditch. In the case of releasing the excavated soil in a bucket to a truck which is on standby at the side of a hydraulic shovel, swing operation and front operation are performed to release the soil. When a control switch 26 is pressed after releasing the soil, even if the working front is off the set direction, the set direction is kept so that swing is automatically performed, and the direction of the working front is returned to the set direction so that the working front is returned to the excavating position before the start of releasing soil. Accordingly, grooving work with release of soil can be performed efficiently.

For example, the first electrode 4 is formed as a + electrode and the second electrode 5 as a - electrode and the DC voltage is impressed between both the electrodes 4 and 5. The stains of the - potential sticking to the clothing 1 to be washed are then migrated to the first electrode 4 side of the + electrode and the stains of the + potential to the second electrode 5 side of the -electrode.  The migrated stains are captured by the first and second porous bodies 2, 3 existing around the respective electrodes 4, 5, by which the washing is executed.

Title: Picture input device in picture data recording system
Inventor: YAMASHITA HITOSHI
IPC: H04N5/372
Filed: 1993-10-28
Abstract: PURPOSE:To output data whose processing time is reduced from the picture input device when a picture is read at a high speed and high picture element density and the data are processed. CONSTITUTION:Picture element data A-D from plural image pickup elements arranged to an optical section 10 whose apertures are adjacent to each other are sequentially stored to line buffers 314-320 from amplifiers 300-306 via switches 310, 312 and fed quickly to a subtractor via a line selector 324. The data are equivalent to picture element data with high resolution comprising 2048X3072 picture elements read from a negative film of 35mm size, for example. A pseudo data generating section 400 generates sequentially pseudo data B'-D' based on the picture element data A from the amplifier 300 for that time and gives the data to the subtractor 500. Thus, the subtractor 500 takes a difference between the original picture element data and the pseudo data from the pseudo data generating section 400 and gives the result to a data processing unit of a work station or the like.
