A process for producing colloidal crystals immobilized with a polymer, comprising the steps of:

Process for producing colloidal crystals immobilized with a polymer and colloidal crystals immobilized with a polymer

A molecular assembly comprising a host metal complex with a space formed therein, and compounds having substituents enclosed in the metal complex within the space and molecular chains bonded to the substituents and extending to the exterior of the metal complex, wherein two or more substituents are enclosed in the same space of the metal complex.

The infrared reflective device includes infrared reflective members which reflect infrared rays. The infrared reflective members include colloidal particles arranged at regular spacing, and a filler material intervening in the spaces between the colloidal particles. The difference between the refractive index of the colloidal particles and the refractive index of the filler material is set so as to be 0.05 or less in the visible light region and 0.1 or above in the infrared region, whereby visible light is transmitted while infrared rays are reflected.

Infrared reflective member, and infrared reflective device and method of making same

A picture display device includes display elements reflecting specific wavelengths of visible light; and shape deformation portions for inducing elastic deformation of the display elements. The individual display elements have colloidal particles arrayed at regular spacing, and an elastically deformable filler material intervening between the colloidal particles. The shape deformation portion includes a shape retention component formed of a material capable of reversible plastic deformation by external force.

A tool and workpiece change system adapted to a machining center with a tool magazine and a pallet pool having a pallet change station and a pallet loading and unloading station and associated with a pallet change apparatus for replacing a pallet on a worktable in the machining center with another pallet successively positioned at the pallet change station. The system comprises a replaceable hand support arranged adjacent the loading and unloading station to detachably support a first replaceable hand for grasping a workpiece and a second replaceable hand for grasping a cutting tool, a workpiece support arranged adjacent the hand support, a tool support arranged adjacent the workpiece support to detachably support a plurality of spare cutting tools, and a robot arranged to be movable between first and second spaced positions. The robot is equipped with the first replaceable hand in the first position for replacing a finished workpiece on a pallet unloaded to the loading and unloading station with a fresh workpiece on the workpiece support and is further equipped with the second replaceable hand in the first position and moved to the second position for replacing a defective or damaged cutting tool in the tool magazine with a spare cutting tool of the same type on the tool support.

Tool and workpiece change system

An industrial robot having a first arm pivotable about an axis and a second arm carried on one end of the first arm for pivot movement about an axis which is parallel to the pivot axis of the first arm. The second arm is composed of an arm body, which carries a rotary member rotatable about an axis normal to the pivot axis of the second arm. A twist body secured to one axial end of the rotary member carries a bend body rotatable about an oblique axis which is slanted with respect to the rotational axis of the rotary member, and the bend body carries a swivel body rotatable about an axis which is slanted with respect to the oblique axis. The twist body is formed at a portion radially offset from the rotational axis of the rotary member with an eccentric cylindrical portion, in which a first pair of shafts for transmitting rotational power respectively to the bend and swivel bodies are rotatably carried in approximately coaxial alignment with each other. Further, a second pair of shafts for respectively rotating the first pair of shafts are rotatably carried in the rotary member, with one of them being in coaxial relation with the rotational axis of the rotary member, but with the other of them being in coaxial relation with one of said first pair of shafts.

Industrial robot

To mount rotatably supporting members such as a rotary shaft to an arm body of an industrial robot arm, the former and the latter are solidly secured to each other by fastening members such as rivets after a bonding agent is applied to spaces formed between the arm body and the rotatably supporting members, whereby necessity for the stage of assembling work by the welding is eliminated, shearing forces are supported by the bonding agent and tensile forces are supported by the fastening members, so that the robot arm being high in precision and mechanical strength can be obtained.

Method of producing an industrial robot arm

A pressure transducer includes a semiconductor diaphragm of a predetermined conductivity having a strain sensitive region capable of being elastically deformed by means of the external pressure applied thereto, a fixing region having a high degree of rigidity, central and peripheral strain sensitive elements disposed along the crystallographic directions thereof and exhibiting high sensitivity and which are respectively insulatingly disposed within the vicinity of the central and peripheral portions of the strain sensitive region of the diaphragm, lead portions insulatingly disposed upon the diaphragm and extending from the strain sensitive region to one side of an end portion in the fixing region for transmitting electrical signals from the sensitive elements, the leads being connected to the central and peripheral strain sensitive elements at one end thereof in order to collectively form a bridge circuit, and electrodes respectively provided upon the other end portions of the lead portions and within the end portion of the fixing region. A supporting member includes a supporting portion for supporting the semiconductor diaphragm through means of the fixing region of the diaphragm, and a leading portion for conducting the electrical signals therethrough, lead wires being connected to the electrodes of the lead portions and being passed through the leading portion of the supporting member. The pressure transducer transmits the electrical signals detected by means of the strain sensitive elements to the electrodes by means of the lead portions and in turn conducts the electrical signals through the lead wires to the processing apparatus. As the pressure transducer does not require internal space for connecting the lead wires to the strain sensitive elements, the pressure transducer is extremely thin and compact and is suitable for mass-production.
