A method for assembling a metal honeycomb catalyzer carrier includes the steps of winding corrugated belt plate materials into a substantially cylindrical shape, forming a wound structure into a predetermined cylindrical shape with a die 101 and pushing out a wound honeycomb body 12 obtained through the forming from the die and inserting the wound honeycomb body 12 into the interior of a tubular member 13. An assembling apparatus 31 includes a winding unit 42 which includes, in turn, a rotational holding shaft 167 and a press roller unit 38, a die unit 39 for forming a wound structure wound round the rotational holding shaft 167 into a wound honeycomb body 12 of a predetermined cylindrical shape (of an outside diameter Dp), a tube support unit 132 for setting a tubular member 13 at an edge of a die surface 126, and a honeycomb push-out and insertion unit 34 for pushing out a formed structure from a die 101 and inserting the formed structure so pushed out into the tubular member 13.

In a wide range focusing camera, a cooperating engagement members are provided in moveable parts of a focusing mechanism and an aperture opening selecting mechanism so as to force the latter into selecting a smaller one of the aperture opening areas when the focusing mechanism is actuated into moving the lens to the position suitable for a close range shot. At the same time, a strobe light is enabled. Thus, the focal depth can be increased, and a clear picture of a close range object can be taken without regard to the condition under which the object is placed in relation with the surrounding objects. Also, a three-dimensional object having a depth can be photographed at close range with a satisfactory result. Because a number of settings required for such close-up shots are instantaneously set either manually by hand or automatically by an auto-focusing mechanism, it is possible even for an inexperienced photographer to take clear pictures of objects at close range.

An inspection device for detecting faulty prints on a printed matter running at a high speed. The prints on the printed matter are held as if they were stopped on account of the employment of an even-numbered polygonal prism which rotates in synchronism with the running speed of the printed matter and which allows an inspector's eye to catch successively the prints on an optical axis not only at their positions on said optical axis but also at their moving positions before and behind said optical axis.

A method of manufacturing a cylindrical body, comprising the step of forming the cylindrical body by bending a plate-like work having first projected finger to fourth projected finger at four corned parts and allowing the end faces thereof to abut on each other, wherein the main surface of the cylindrical body on the side where sags are present is formed in an outer peripheral wall surface and the rear surface thereof on the side where the burrs are present is formed in an inner peripheral wall surface, and a first projected part is formed of the first projected finger and the third projected finger and a second projected part is formed of the second projected finger and the fourth projected finger. After the cylindrical body is held by friction stir welding devices, the probe of a friction stir welding tool is buried from the direction of either of the first projected part and the second projected part, and scanned in the direction of the other of the second projected part and the first projected part. The probe is buried and scanned in the state of being displaced to an advancing side.

A method of manufacturing a wheel rim by bringing end faces of a workpiece into abutment against each other to form a hollow cylindrical body and forming a circumferential recess which is depressed from an outer circumferential wall of said hollow cylindrical body toward an inner circumferential wall thereof, including providing protrusions disposed near ends of a joined area of the hollow cylindrical body and extending in a joining direction, and then pressing the outer circumferential wall of the hollow cylindrical body to form the recess.

In order to prevent an electrode tip 8 from being burred during dressing process, thereby attaining high quality and stability of the electrode tip, a tip dresser features a screw-threaded circumference 5 formed around the rotatable cutter holder 1 for securing a one- or two-piece formed cutter element 2, for permitting the holder 1 to be rotated in one direction A manually or by a suitable driver. Frusto-conical recesses are symmetrically formed in both sides of the holder 1 for receiving the electrode tips, allowing the cutter element 2 to be mounted so as to slightly extend by a predetermined amount beyond the conically recessed surface. Another feature is in the form of apertures 6 and 7 provided through the holder 1 for discharging the cutting chips: one aperture 6 formed on the forward front side of the rotating direction of one machining edge 2a for the bevel surface of electrode tip 8, and another one 7 on the forward front side of rotating direction of another machining edge 2b for the end surface machining. The aperture 6 is formed along the edge 2a, and aperture 7 is formed so as to reach at least the boundary between the bottom and the conical side surface of each of the frusto-conical recesses.

In an electrode tip dressing apparatus, a relatively weak pressure is applied on an electrode tip at the electrode setting, then a strong pressure is applied at finishing, and finally a lowered pressure is applied after a predetermined time period. The blade holder is provided with a clearance over the entire length of the blade for discharging the chips produced during machining of the electrode tip, thereby preventing blinding of blades caused by cutting chips.

A terminal switching control apparatus, used for a combination of a voice terminal device and a non-voice terminal device, comprises a call signal recognition detector to detect an incoming signal and distinguish the detected signal between an voice signal and an non-voice terminal call signal, a device for transmitting a response message to urge the calling party to respond if no incoming voice signal is detected, an action request device for urging the called party to respond by the voice terminal device when an incoming voice signal is recognized after transmitting the response message, a control device for switching the line connection to the non-voice terminal device if neither the voice signal nor the non-voice signal is detected by the call recognition device, and a set of mode selector switches for selecting a presence mode and an absence mode according to the presence/absence status of the called party. The presence/absence mode can also be controlled automatically to conform to the presence/absence status of the called party.
