Title: Foundation pile
Inventor: KUSANO KENJI
IPC: E04H17/22
Filed: 1995-01-24
Abstract: PURPOSE: To provide a foundation pile driven in the ground and excellent in corrosion prevention efficiency when gate door, fence, etc., are constructed. CONSTITUTION: A foundation pile 4 is constituted of a core layer 1 of metal and a corrosion proofing layer 2 preventing the corrosion of the metal covering the outside surface of the core layer 1, and the corrosion proofing layer 2 is formed of a corrosion proofing material 3b containing ceramic particles 3a. Since the ceramic particles 3a have a sufficient hardness against friction or impact generating when the foundation pile 4 is driven into the ground, it can be prevented that the corrosion proofing layer 2 is damaged, and the metal of the core layer 1 is exposed. The foundation pile 4 is excellent in corrosion proofing efficiency even if it is buried into the ground for a long period of time because corrosion proofing function of the corrosion proofing material 3b covering the core layer 1 is not damaged.

Title: Rotary stopper device for shaft lock
Inventor: TANIO KOJI
IPC: G06F1/16
Filed: 1991-01-29
Abstract: PURPOSE:To highly precisely control rotary motion to prevent the failure of a case and the peeling of paint by providing a shaft for a shaft lock with a rotary plate, and moreover a fixing bracket for the shaft lock with a stopper with which the rotary plate engages. CONSTITUTION:A neck part 9 of a case 6 to enclose the display 14 of a lap top type personal computer or the like is provided with a hole, and the shaft 11 of a shaft lock 1 is inserted in the hole to fix the case 6 with an apparatus body 7. The shaft lock 1 is fixed to a boss 12 with a screw. When the opening and closing motion of the display 14 causes the rotation of the bracket 4 of the shaft lock 1, the rotation is stopped at a position where the notched part 8 of a rotary plate 3 comes into contact with a stopper 5. Thus since the stopper 5 has unitedly formed with the shaft lock 1, the attaching and detaching of the stopper 5 can be easily done, and moreover the range of shaft rotation can be optionally controlled by exchanging the rotary plate 3.

Title: Ink jet recorder
Inventor: MARUYAMA MITSUAKI
IPC: B41J2/165
Filed: 1984-01-20
Abstract: PURPOSE:To completely recover ink (prevent ink from splashing) and to improve cap and pump efficiency by reliably removing air bubbles at ink charging (recharging) time. CONSTITUTION:A suction pump is mounted obliquely, and a unidirectional valve 147 is disposed above a pressure chamber. Thus, the air in the pressure chamber of initial suction is rapidly removed. Since an air intake valve 122 for intaking air is employed in the cap of a head 141, the remaining ink in the cap 141 is reliably taken-in after sucking operation, and the ink is prevented from splashing or leaking from the nozzle surface upon opening of the cap. Not only the contamination of the nozzle face but the small rise of viscosity at the end of the nozzle can be prevented by mounting a housing 113 which receives ink jet from a nozzle cleaner 111 and a nozzle 142, and the ink jet can be accordingly always stably performed.

Abstract: PURPOSE: To eliminate the change in toner defining amount and achieve the stabilization of development by so fixing the toner amount defining member for defining the amount of the magnetic toner being conveyed on a sleeve that its end defining part goes toward the center of a magnet roll.  
     CONSTITUTION: The support members 10 provided on both sides of the revolving shaft 3 of a magnet roll 1 support the revolving shaft 3 oscillatably about the support shaft 11 fixed to a developing tank 5. A toner defining member 9 is so provided that its end defining part goes toward the center of the magnet roll 1 and the end of the defining member 9 is so fixed to the support shaft 11 that it rides on the line nearly the same as the straight line connecting the fulcrum 11a and the center of the revolving shaft 3. Even if with such constitution the photosensitive drum deviates and the magnet roll 1 deviates along with this, the change in the spacing between the end defining part of the defining member 9 and the surface of the magnet roll 1 is extremely small, hence the change in the toner defining amount is small as well, thus the stable development may be obtained.

Title: Apparatus for the measurement of gravitational fields
Inventor: VERYASKIN ALEXEY VLADIMIROVICH
IPC: G01V7/02
Filed: 1995-10-04
Abstract: Apparatus for measuring gravitational fields comprising a superconducting string (1) fixed at both ends and forming part of a closed superconduction loop inductively coupled to two driving solenoids (Ld1, Ld2). Displacement of the string in response to a gravitational field is sensed by two magnetic flux transformers each comprising a signal coil and two pick-up coils (Lp1, Lp2). Pairs of pick-up coils lie in two perpendicular planes providing two independent channels of measurements. The two arms of each flux transformer are balanced to convert only the amplitudes of the string's antisymmetric natural modes into an output voltage. The output voltage of each channel is used to produce a feed-back current distribution (Iy1, Iy2) proximate and parallel to the string. By adjusting the feed-back current, the effective relaxation time and resonant frequency of the first antisymmetric mode of the string can be adjusted, while leaving the symmetric modes unchanged, thus increasing the apparatus sensitivity to gravity gradients.
