A binder for a document capable of providing excellent usability and workability by improving so that only the advantages of a conventional lever arch type ring binding implement can be utilized to increase the opening of a ring. The binding implement comprises a base part, the ring mounted on the base part and changeable between a closed attitude for binding the document and an open attitude in which the closed ring is partially opened to bind the document, and a switching mechanism mounted on the base part and switching the ring between the closed attitude and the open attitude. The ring comprises a first ring member and a second ring member brought into the open attitude and the closed attitude by the contact of the end parts thereof with each other or the separation of the end parts thereof from each other. The switching mechanism comprises a select lever swingably fitted to the base part. When the ring is in the open attitude, the select lever is so set that it can pass the opened portion of the ring and that the opening/closing speeds of the first ring member and the second ring member of the ring are different from each other.

An object of the invention is to realize high-accuracy analysis of a flue gas in terms of a trace amount of ammonia so as to control the level of ammonia gas to be added to a flue gas NOx removal apparatus. Since the ammonia gas to be determined is a highly adsorbable, the gas component is considerably adsorbed on a surface of the flue gas sampling tube during sampling of flue gas. When a conventional sampling method including heating a gas sampling tube is employed, the amount of sampled gas is reduced through adsorption during gas sampling, failing to obtain concentration values at high accuracy. Thus, a high-accuracy gas sampling method replacing a conventional, heating-based method includes completely washing out, with an absorption liquid therefor serving as a washing liquid, a target ammonia gas deposited on the inner wall of a flue gas sampling tube (2), whereby the gas component is thoroughly collected. Through analysis of the thus-obtained washing liquid, high-accuracy analysis can be attained.

A printed wiring board has a first wiring layer formed at least on one surface of an insulative substrate, an insulating layer formed as covering the first wiring layer, and a second wiring layer formed on the insulating layer. The insulating layer is formed of a cured insulative sheet made of a high-stiff sheet-type reinforcing material containing resin. The first and second wiring layers are electrically connected to each other through at least one hole having a bottom. The second wiring layer is united with the insulating layer at an interface thereof with a conductive material of the second wiring layer injected into concave sections provided on the interface. Another printed wiring board has an insulative substrate having a first surface and a second surface, a first insulating layer and a second insulating layer formed on the first surface and the second surface, respectively, and a first wiring layer formed on the first insulating layer and a second wiring layer formed on the second insulating layer. The first and second wiring layers are electrically connected to each other via at least one through hole. The first wiring layer is united with the first insulating layer at an interface thereof with a conductive material of the first wiring layer injected into concave sections provided on the interface. The second wiring layer is united with the second insulating layer at an interface thereof with a conductive material of the first wiring layer injected into concave sections provided on the interface.

A mid-mount mower having a front frame unit including a pair of right and left front longitudinal frames, a first cross frame interconnecting the front longitudinal frames in forward positions thereof longitudinally of the vehicle body, and a second cross frame interconnecting the front longitudinal frames in rearward positions thereof longitudinally of the vehicle body, the front frame unit supporting the front wheel unit and also supporting a lift mechanism for vertically movably suspending the mower unit; a rear frame unit including a pair of right and left rear longitudinal frames, the rear frame unit being connected to the front frame unit; and a rear wheel drive unit interconnecting the rear longitudinal frames. The second cross frame has a downwardly opening recess disposed adjacent a middle position thereof, the recess allowing entry thereto of an upwardly protruding portion of the mower unit without interference when the mower unit is raised by the lift mechanism. The second cross frame includes a first profile member (13a) having a gate-shape portion (13aa) defining a recess (28) and horizontal plate portions (13ab) connected respectively to lower ends of the gate-shape portion, and a vertical plate member (13b) connected to a rear end surface of the first profile member.

A tractor having a mid-mount type mower includes a pair of frames extending in a fore and aft direction, and a transmission case extending and supported between the pair of frames. The transmission case houses a power takeoff clutch disposed above a rear wheel differential. A change speed gearing mechanism is disposed between a front surface of the transmission case and the rear wheel differential. With such an arrangement of the components, the transmission case has a reduced length in the fore and aft direction.

A library apparatus in which a plurality of cell drums are divided into two groups respectively placed on the left and right side of a recording/reproducing unit placed in a central part thereof. In this library apparatus, rails are placed in a direction along which the cell drums and the recording/reproducing unit are arranged. The conveying of media, which are contained in the cell drums placed on the left side of the recording/reproducing unit, is assigned to an accessor placed on the left side thereof. Simultaneously, the conveying of media, which are contained in the cell drums placed on the right side of the recording/reproducing unit, is assigned to an accessor placed on the right side thereof. A robot hand of each of the accessors is opened and closed by a turn of a motor. At that time, a power supply is turned off. Moreover, the robot hand is prevented by a locking mechanism from popping out of the accessor. Furthermore, ordinary cartridges are discriminated from cleaning cartridges.
摘要:
When a second switching element Q.sub.2 is changed over from ON state to OFF state for each switching cycle while a first switching element Q.sub.1 remains ON in a unit weld period T.sub.a for example, a primary current I.sub.1 does not come to a stop at once under the influence of inductance of a welding transformer 16 but it flows as a transient current i through a primary circuit until it is off. The transient current i makes a closed circuit through which it flows from a primary coil of the welding transformer 16 via a third diode D.sub.3 and then a first switching element Q.sub.1 again into the primary coil of the welding transformer 16. More specifically, due to the first switching element Q.sub.1 being kept ON, the transient current i which has passed through the third diode D.sub.3 flows through the first switching element Q.sub.1, without passing through a capacitor 12, and comes back into the primary coil of the welding transformer. Little or substantially no current flows through the capacitor 12.
