Title: Simple attachment/detachment suction cup mechanism
Inventor: NAGAOKA ETSUO
IPC: B63C11/52
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To iniaturize a simple attachment/detachment suction cup mechanism, and to facilitate the suction or separation effect of a device in water in the suction cup mechanism used in fixing an underwater wall surface inspection device or the like. SOLUTION: The pressurized water is continuously fed to an upper chamber A side from a feed nozzle 1-a of a hollow cylinder 1, and when the pressure exceeds the pressure in a lower chamber B, a hollow two-shaft piston is pressed toward a wall surface 20 side by the differential pressure to bottom a suction cup 3. The water in the suction cup 3 is sucked in the discharge flow direction toward an ejection nozzle 2-4 for generating the whirl which is eccentrically arranged upwardly from the center piercing a piston shaft 2-3 part on the upper chamber A side to suck the wall surface and the suction cup by each other.  In separating the suction cup, the feed of the pressurized water into the upper chamber A is stopped to release the suction effect, and the hollow two-shaft piston is returned by the differential pressure from the outside water pressure by the sealed gas in the lower chamber B, enabling the suction cup to be easily separated from the wall surface 20.

Title: Led display device
Inventor: SHIMIZU YOSHINORI
IPC: G09F9/30
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To lessen reduction in the luminous efficiency of a white light-emitting diode and a color shift of the color of emitted light at the high luminance of the above diode and even under the environment of the long-time use of the above diode, by a method wherein the white light-emitting diode is arranged to one picture element in addition to a light-emitting diode, which can emit red light, green light and blue light. SOLUTION: A white light-emitting diode is formed by combining a luminous layer with a gallium nitride compound semiconductor element having a high-energy band gap and a yttrium aluminium garnet fluorescent substance activated by cerium, which is a photoluminescence fluorescent substance. As a result, even in the case where high-energy light in the range of visible light emitted from a light-emitting element is radiated on the vicinity of the range at the high luminance of the diode for a long time, the white light-emitting diode can be formed into a light-emitting diode, which is very little in a color shift of the color of emitted light and reduction in a luminous luminance.  Specially, blue light emission of an InGaN diode, which is used as a nitride compound semiconductor diode and the absorption spectrum of the yttrium aluminium garnet fluorescent substance activated by the cerium coincide well with each other.

Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To enable practices even at general home by forming small holes uniformly in one or both of a bow and an edge constituting a cymbal and then absorbing percussion energy. SOLUTION: Small holes 15A in a large shape of, for example, 4 mmϕare bored in part of the edge 13 and bow 13 and outside a cup 11 and small holes 15B in a small shape of about 2.5 mmϕ are bored inside the bow 13 and cup 11. Preferably, an area (d) where no small hole 15A is present is formed to about 8 to 10 mm at the outer periphery of the edge 14. Further, the intervals of the small holes 15A are preferably increased on their concentric circles toward the outer periphery. Nodes J of projection parts are present between the cup 11 and bow 13. A sound of a clear timbre including a high-frequency component like 'whop' is obtained because of the presence of the nodes J by striking the cup 11. Consequently, percussion energy is absorbed by the parts of the respective small holes and the cymbal never resonates.

IPC: G01B11/24
Filed: 1993-12-30
Abstract: PURPOSE:To accurately measure a shape of a surface of a plunger by a simple structure by detecting an image signal of each line of a reflection light that is reflected on a circumferential surface of the plunger. CONSTITUTION:When a line fiber light source 2 emits a line type emission light L1 on a plunger 3 to be measured, only a reflection light L2 reflected by a circumferential portion where there is not an irregular shape of a surface of the plunger 3 is inputted to a one-dimensional CCD camera 5 in which image- pickup elements are arranged in a direction parallel to an axle of the plunger 3. The reflection light L2 is imaged via a lens 4 so that one line of image corresponding to the shape of the surface of the plunger 3 with high contrast is formed and an image signal S1 is A/D converted by an A/D convertor 7 in an image processing section 6. These operations are continued until the plunger 3 is rotated 360 degrees and data D1 of a plurality of lines corresponding to the shape of the whole surface of the plunger 3 is recorded in a memory 8. A CPU 11 reads data D1 of a plurality of lines to form a two-dimensional image, thereby measuring the shape of the surface of the plunger 3.

IPC: H01S3/07
Filed: 1992-12-17
Abstract: PURPOSE:To achieve excellent exciting efficiency and a module shape by forming the flat shape such as an ellipse for the cross-sectional shape of the core of a fiber- shaped light emitting element so that the size of the cross section of the core is larger than the cross section of luminous flux with respect to the excited light having the luminous flux of the cross section, which is approximate to the flat elliptical shape. CONSTITUTION:A light emitting region 9 of a semiconductor laser, which is to become an exciting light source, is arranged. The width in the parallel direction with a PN junction is made to be Wa, and the thickness is made to be hd. The very flat shape is obtained. Meanwhile, a fiber-shaped light emitting element is made to be an elliptical flat core 11, wherein the refractive index is n1 and a laser medium is added. The major axis of the core is made to be Wf, and minor axis is made to be df. A clad 12, which does not contain laser medium and has the refractive index lower than the core 11, is provided. Therefore when the core is manufactured so as to obtain Wf>=Wd and df>=hd and the direction of the PN junction of the exciting light source is made to agree with the major axis of the ellipse of the core, the exciting light can be combined with the fiber without using the light condensing system such as a lens. As a result, the exciting light can be cast into the core of the fiber efficiently.

Abstract: PROBLEM TO BE SOLVED: To improve an assembly work using an automatic assembler by forming an annular protrusion which comes into contact with the internal wall of a barrel for storing ink in a tightly sealed state against a liquid and ribs of a larger diameter than the annular protrusion, in the longitudinal direction, on the outer wall. SOLUTION: A tail plug body 7 with a formed annular protrusion 4 and an annular outer wall 6 with ring strips are arranged at different positions in the longitudinal direction and both tail plug body 7 and annular outer wall 6 are connected together with a plurality of protruding strips 5. Under this structure, a position for the annular outer wall 6 to be formed can be properly selected within the range for the protruding strips 5 to be formed. However, a broad space 8 is more preferably formed in the backward part from the tail plug body 7 from the viewpoint of securing a breathing path. In addition, the annular outer wall 6 serves as a gripping part to a machine during automatic assembling and in such a relationship that the wall 6 mutually supplements the strength of the space 8 with the protruding strips while securing the space 8.  Thus it is possible to obtain a best suited writing utensil for the assemby work by an automatic assembler using the tail plug of a simple structure.

IPC: F25B9/02
Filed: 1992-12-18
Abstract: PURPOSE:To raise an operating efficiency of a refrigerator and to perform a stable operation by limiting a flow rate of refrigerant flowing to a high pressure circuit of a Joule-Thomson refrigerating circuit at the time of high load of an apparatus required to be cryogenically cooled. CONSTITUTION:A flow rate of refrigerant flowing to a high pressure circuit of a Joule-Thomson circuit 10 is limited for a predetermined time when an apparatus required to be cryogenically cooled. When the apparatus is a superconducting coil, a load is largely increased at the time of exciting and degaussing. Then, the high pressure circuit of the circuit 10 is closed simultaneously upon exciting, and so controlled as to open the high pressure circuit for 30 to 1min and 30sec by using a timer and control means after the degaussing. Helium gas is merely sucked from the low pressure circuit from a liquid helium tank 1 during closing of the high pressure circuit. Thus, in the case of Joule-Thomson control, an internal pressure rise of the tank 1 can be suppressed as compared with the case of no such control.
