Filed: 1993-02-10
Abstract: PURPOSE:To prevent the restart of a pump in the reverse revolution state due to the couterflow of liquefied gas due to the stop of the pump by installing a reverse revolution preventing mechanism, as for the submersible pump consisting of a pump part consisting of an impeller and a casing for accommodating the rotary shaft of the impeller and a driving part which is directly connected with the rotary shaft and revolves the impeller. CONSTITUTION:An impeller 1 and a rotary shaft 2 and an outer race 4 and a cam 5 are revolved by a plurality of motors 7a and 7b, respectively. While, an inner race 6 is fixed on a head cover 8. Since, the moment acting around the contact point between the cam 5 with the outer race 4 increases, when the constitution parts 1-4 are not in revolution, the cam 5 contacts the inner race 6. Further, since the contact point with the inner race 6 does not exist when the constitution parts 1-4 and the cam 5 revolve in the normal direction and at least a prescribed number of revolution is obtained, the cam 5 is not worn out. Further, since the cam 5 meshes with the inner race 6 and the outer race 4 and the reverse revolution is prevented, when the constitution parts 1-4 reversely revolve, the rotary body is not applied with an unreasonable force, and even in an electric supply fault, a pump is restarted simultaneously with the switching of an emergent electric power source, and the stable production of gas is enabled.

Abstract: PURPOSE:To prevent the disconnection from a word line by only etching the periphery of a recessed part a little by a method wherein a gate electrode is formed on sidewalls of the recessed part and in the periphery at an opening part of the recessed part. CONSTITUTION:A gate insulating film 28 is formed on the surface of a recessed part 24 and on the surface of a semiconductor substrate 21 surrounded by a LOCOS film 22. A gate electrode 29 is formed, via the gate insulating film 28, on sidewalls of the recessed part 24, in the periphery of the bottom adjacent to the sidewalls and in the periphery of an opening part of the recessed part 24. The gate electrode 29 is formed of a polysilicon film, and phosphorus is diffused to it. About the half of an element region 23 surrounded by the LOCOS film 22 is covered with the gate electrode 29; the electrode is extended in the upward and downward directions and forms a structure united to a word line. As a method to form the gate electrode 29, the recessed part 24 is first filled completely with polysilicon, and an etching-back operation is executed. In succession, the polysilicon is laminated again in the horizontal direction. After that, the outside of a region to be used as a guard is removed by an etching operation; then, the recessed part in the center is formed by an etching operation. Consequently, the electrode can be formed without a fear that it is disconnected from the word line.

Title: Cathode jig for electroplating
Inventor: TAKAGI MASAMI
IPC: C25D17/22
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To simplify assembly work by inserting plural pieces of cathode pieces erected on the surface of a cathode base plate into an insulating layer in the state of exposing the front ends of these cathode pieces on the surface. SOLUTION: Plural cathode pieces 2 each of which is arranged longitudinally and transversely are erected on the surface of the cathode base plate 1 by this jig. The cathode pieces 2 are embedded into the insulating layer 3 in the state of exposing the front ends of the respective cathode pieces 2. As a result, the respective cathode pieces 2 are integrated via the base plane 1 and there is no more need for connecting lead wires by soldering and, therefore, the assembly work is simplified. If the front ends of the cathode pieces 2 are cured nearly parallel with the surface of the insulating layer 3, the exposing of the front ends of the cathode pieces 2 at the large area on the surface of the insulating layer 3 is made possible. As a result, the contact time of the material to be plated with the cathode pieces 2 is prolonged and the plating efficiency is enhanced.

Title: Revolving and holding device for flat plate type recording carrier
Inventor: SHIOZUKA KAZUMASA
IPC: G11B17/028
Filed: 1984-02-13
Abstract: PURPOSE:To obtain the excellent revolving/holding capacity by putting a projected bar connected to an elastic member into a holding tool which holds with pressure a flat plate type information recording carrier fitted into a rotary shaft body and then fixing the holding tool to said shaft body with frictional force by means of said projected bar in a fit mode. CONSTITUTION:Two holes 11, for example, are formed inside a holding tool 1 and toward th center of the tool 1, and a ball-shaped projection matter 13 containing an elastic matter 12 like a spring, etc. is put into those holes 11 respectively. These matters 13 are semifixed by screw 14, etc. The pressing force of the matter 13 can be varied by changing the position of the screws 14 and therefore by the expansion/contraction of the spring. Such a tool 1 is set with pressure into a rotary shaft body 2 containing a disk D. Thus it is possible to obtain the holding power that can withstand the revolution by the force of the matter 13 which presses the circumferential surface of the body 2. Thus the center hole of the disk D in never injured since the body 2 has no projection. In addition, the body 2 can be easily processed with simple attaching/detaching of the body 2.

Filed: 1991-02-18
Abstract: PURPOSE:To measure volume and weight in the same atmosphere without a larger sample chamber by a method wherein a mechanism is provided to transmit the weight of a sample to a weight measuring device provided outside a sample chamber and a sealing mechanism free to detach is provided to make a partition therebetween. CONSTITUTION:A sample W of powder and grains to be measured is placed into a sample container 9 and a lid 11 is removed to put the container on a sample base 5. Then, the lid 11 is closed securely with an O ring 7 so as to keep the lid 11 airtight with a sample chamber block 10. Upon the end of this setting, a helium gas purging is performed in the sample chamber. Here, the sample base 5 is lifted up. If so, as a hole 10a exists on the bottom of the sample chamber 1, an ambient atmosphere of the sample W is replaced with a helium gas. Under such a condition, a weighed value of an electronic balance 3 is read out and a tare is subtracted from the results to obtain the weight of the sample W. Then, a tiny lid 6 is opened and a knob 40a is turned to push up the sample base 5 and the sample base is kept airtight with the block 10 by a ring 4. Thereafter, the lid 6 is closed to seal the sample chamber 1 and a volume is measured in a piping system 2 based on a gas capacity method.

Title: Optical guide tube
Inventor: SAKAGUCHI SHIGEKI
IPC: C03C25/42
Filed: 1979-03-02
Abstract: PURPOSE: To improve the fracture strength of the optical guide tube and maintain the safety of long-term strength by sealing cylindrical metal or metal wires in the glass of the circumferential portion of the optical guide tube.  
     CONSTITUTION: The circumference of core glass 1 is coated with the clad glass 2 having a refractive index smaller than the refractive index of the core glass 1 and cylindrical metal is sealed into this clad glass 2. It is also possible to seal fibrous metal wires therein place of the cylindrical metal. In this way, the optical guide tube may be made difficult to break. When the metal of the coefficient of thermal expansion slightly larger than the coefficient of thermal expansion of the sealed glass is used, compressive stress remains in the glass through cooling from the sealing temperature down to ordinary temperature, and this makes the optical guide difficult to break. In some instances, the flaw existing in the glass surface of the outer side grows owing to moisture and causes the glass to crack, but the growth of the flow to the inner glass is prevented by the cylindrical metal. In this way, the intensity of the optical guide is improved.
