Title: Cylindrical drain structure and method of weak-ground improving construction by cylindrical drain structure
Inventor: SUGIOKA TOSHIJI
IPC: E02D3/10
Filed: 1995-03-23
Abstract: PURPOSE: To improve drainage performance by fitting a beltlike drain body on the peripheral wall of a cylindrical coating body and preparing a pile while using industrial waste as fillers to a water-permeable cylindrical drain body mounted so as to be crossed with the beltlike drain body. CONSTITUTION: A plurality of thin beltlike drain bodies 2 in narrow width are installed in parallel on the outer circumferential wall surface of a cylindrical coating body 1 from an end to an end along a bus direction. The mounting ratio of the beltlike drain bodies 1 in narrow width to the outer circumferential surface of the cylindrical coating body 1 is changed in response to the extent of the water permeability of fillers charged into the cylindrical coating body 1. When water permeability can depend upon sand pile itself largely, moisture pressed in the ground is passed through the water-permeable cylindrical coating body 1 and collected by the fillers having water permeability on the inside and drained.  When the water permeability of the fillers charged into the cylindrical coating body 1 cannot be expected so much, the fillers conduct action, in which the weak ground is pressed in the horizontal direction and moisture in the ground is pressed and collected to the beltlike drain bodies 2.

Title: Automatic medium issuing system
Inventor: NAKADA MASATO
IPC: G06Q20/18
Filed: 1990-04-05
Abstract: PURPOSE:To construct a low-pricesed system to enable flexible correspondence by connecting plural terminals and a medium issuing machine by an interface different from a network. CONSTITUTION:Interfaces 30 and 31 are provided separately from a network 10. An automatic medium issuing machine 40 is connected through the interface 30 to one of plural terminals 1-(n) and for the plural terminals 1-(n), the adjacent terminals are connected in a row by the interface 31 or the like. In such a way, since the plural terminals 1-(n) and one medium issuing machine 40 are connected not through the network 10 to be connected to a host computer 13 but through the interfaces 30 and 31 separate from this network, issuing work from the plural terminals 1-(n) can be processed by one medium issuing machine 40 without directly depending on the specification of the existent network 10. Thus, the low-priced system can be constructed to make flexible correspondence to the request of a shop.

IPC: E21D11/38
Filed: 1993-03-24
Abstract: PURPOSE:To prevent the water leak of a joint part by a seal following the repeated deformation of a segment ring under construction and also capable of closing a large aperture. CONSTITUTION:A water expansion body storage area 6s is provided in an elastic body 6, and a water expansion body 9 such as water expansion rubber is disposed in the water expansion body storage area 6s to form a seal 5.

Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To eliminate positional shift by forming a protrusion, i.e., an island, matching the arranging pitch of a pressure generating chamber integrally with an elastically deformable polymer film of varnish-like polymer thereby composing an elastic plate. SOLUTION: When etching is performed after a photosensitive glass plate 1 is secured to a working substrate 2 and a window 3 matching the projected profile of an island is formed of photoresist 4 on the surface, a through hole 5 is made in a region corresponding to the island. The glass plate 1 is then coated uniformly with varnish-like polyimide 6 such that a thickness suitable for a diaphragm part is obtained after solvent is evaporated. When a polyimide film 7 is stripped off from the substrate 2 at a stage where the polyimide film 7 is formed after solvent is evaporated from polyimide 6, a protrusion 8 is formed in a region of polyimide film 7 for forming the island and an elastic plate is completed. Since the island, i.e., the protrusion 8, is secured to polyimide film without using any adhesive, positional shift does not take place.

Filed: 1991-03-28
Abstract: PURPOSE:To prevent the contamination of a film forming chamber by extending a shielding plate to a shielding frame to cover the surface of a target and forming a sputtering hole to expose the erosion region of the target on this shielding plate. CONSTITUTION:The sputtering hole 27 is formed in the part of the shielding plate 25 corresponding to the erosion region of the target 22. Particles are splashed from only the exposed part of the sputtering hole 27 and deposit on a work when a sputtering cathode 20 is used for film formation. The particles splashing from the other target 20 in a sputtering chamber stick to the entire surface of the sputtering cathode 20 but the particles sticking to the erosion region of the target 22 are utilized for a film formation treatment and the particles sticking to the shielding plate 25 are not easily peeled. The peeled matters of the sticked particles do not fly to the sputtering chamber and do not contaminate the chamber at the time of the film formation and, therefore, the yield of the film forming treatment is improved.

Abstract: PURPOSE: To heighten the accuracy of measurement by simple operation, by detecing the difference of heat conductivity before and after absorbing carbon dioxide by means of a carbon dioxide absorption tube.  
     CONSTITUTION: The differential signals of heat-conductivity cells 11, 12 are recorded as signals in an ideal fixed level (the mean value) in the case of pass because sample gas introduced to chambers A or B, which have the maximum volume as a uniform layer by the functioning of a piston drive mechanism 15 and the operation of an opening-and-closing valve, is induced to a measuring and discharge flow path 7 as a uniform layer by opening opening-and-closing valves 3, 5 or opening- and-closing valves 2, 6. The peak area can also be recorded easily to a recorder 13 by multiplying the height of levels by continuous time, and the continuous time becomes to a constant because pump stroke time is fixed. Thus, the concentration of the carbon dioxide of living bodies can immediately be read by the height of peak before and after record.

IPC: H02M3/28
Filed: 1980-07-01
Abstract: PURPOSE:To realize a protection of overcurrent through a simple constitution, by monitoring the feedback voltage and reducing the on-time of a switching element when the feedback voltage becomes less than a certain level. CONSTITUTION:In the normal state the output Ea of an error amplifier 5 is larger tnan the output Eb of an error amplifier 9, and the output voltage EO is controlled at the side of the amplifier 5. When the voltage EO becomes small with an overload, the feedback voltage Ef also becomes small. If Ef<(Es+El)/2 [El: limit value, El=(R5+R6)R8.Es/R6(R7+R8)], Ea<Eb is obtained. As a result, an operation is obtained at the side of the amplifier 9 to reduce the on-time of a transistor (TR)2, and accordingly the increase of the output current is stopped to ensure a protection of overcurrent. In this case, a capacitor C is provided at a feedback circuit of the amplifier 9 to avoid the fact that the TR2 does not generate heat with the on-off of several times in a period. Thus the time of response is controlled.
