Abstract: PURPOSE: To mass-produce the square shape at low cost through the continuous rolling line, by passing the material successively through the breakdown mill, the forming mill and the reforming mill, on purpose to carry out the reform rolling work so as to make the edges of two sides on the opening side to contact each other.  
     CONSTITUTION: After the flat slab as the material is heated and soaked to suitable temperatures, the slab is sent to the breakdown mill 10, by which the slab is roughly rolled through three passes into a rough shaped steel material 4 possessing the section of approximately W-character gently sloped with low height and wide breadth. Next, this steel material 4 is passed through the forming mill 11 like as the two-high caliber mill, etc., and the open-cup type open-top steel material 6 is formed. In this steel material 6, the corners of the sides 6b, 6c, are located on the center line L of the pass line. The steel material 6 is rolled by the reforming mill 12 like as the two-high caliber mill, etc., in the direction to make each couple of adjoining two sides 7b, 7c, and two sides 7a, 7d, on the opening side, both to mutually approach; and the edges of two sides 7a, 7d, are made to contact by the caliber 12c, to obtain the square steel material 7 with enclosed section; then, the seams are welded or forge-welded, and the final product is obtained through the straightening process.

Abstract: PURPOSE: To facilitate the attachment and detachment of a cleaner by mounting a base plate rotatably on the platform of a separate unit, which is equipped with a transfer material separating belt, and by mounting the cleaning member for the aforementioned member on the base plate.  
     CONSTITUTION: A cleaner base plate 31, which is made rotatable about a shaft 35 so as to normally bias a coil spring 33 in the clockwise direction, is attached to the platform 7 of a separate unit U which is equipped with a separating belt 13 through a drive roller 14 and pulleys 8 to 12. A cleaner pad 29 having a grip 36 is mounted in a cleaner holder 30 fixed to the base plate 31. In order to replace the cleaner pad 29, the unit U is turned to a preset position apart from the apparatus body. After that, the base plate 31 is truned counter-clockwise by means of a lever 32 against the force of the coil spring 33 to release the forced contact between the pad 29 and the separating belt 13. Then, the pad 29 is extracted from the holder 30 through the grip 36, and a new cleaner is mounted thereafter.

Title: Foamed resin block for temporary road and construction of temporary road
Inventor: OTAKI TSUNEO
IPC: E01C9/08
Filed: 1993-03-25
Abstract: PURPOSE:To eliminate deformation of blocks and reuse repeatedly blocks, by coating the edge of foamed resin with a metallic frame having discontinuous part to form blocks for a temporary road. CONSTITUTION:The edge of a foamed resin 2 is coated with a metallic frame so as not to suffer damage at the edge. And discontinuous parts 13 are formed at the side edges of the metallic frame coating the edge When a load has actuated on the block 1, the foamed resin absorbs the load by the elastic deformation thereof. On the other hand, when a load is removed, the block recovers the original form by the restoring force. A plurality of blocks 1 are laid down and connected to each other and then a covering slab or the like is palaced thereon to complete a temporary road. Accordingly, Since the edges are protected by a metallic frame and the metallic frame is protected from deforming by discontinuous parts 13, the blocks can be prevented from breaking.

Title: Ink-jet recording device
Inventor: KOIKE YASUSHI
IPC: B41J29/13
Filed: 1994-04-05
Abstract: PURPOSE:To prevent the lowering of recording quality level which is caused through damage of an expediter in the case of replacing a cartridge by releasing pressing force in the direction of the platen of a rotor in accordance with the opening/closing angle of a cover and furthermore releasing the contact state of the rotor. CONSTITUTION:When a cover 15 is opened in a time for replacing a cartridge, a spur holder 14 is rocked around a fulcrum 14a by action of a pressing spring 16 while an expediter 11 holds a pressing state for a platen 9. Therein, when the cover 15 is opened at a specific angle alpha, the spur holder 14 is rocked in the direction of the platen by action of the pressing spring 16 and stopped in the position of a specific angle beta by a stopper provided in the cover 15. Furthermore, when the cover 15 is opened, the spur holder 14 is turned together with the cover 15 while it is stopped and fixed in the position of the specific angle beta. Therefore, a head cartridge 1 does not interfere with the expediter 11. Thereby deterioration of recording quality level is prevented which is caused by damage of the expediter 11.

Title: Semiconductor circuit
Inventor: KUBO KAZUYA
IPC: G11C19/28
Filed: 1989-03-17
Abstract: PURPOSE:To decrease the effect of a noise even when a load indicates a capacitive impedance by connecting an impedance element to the section between an output terminal connected to a driving transistor (TR) and a direct current voltage source corresponding to an L level. CONSTITUTION:A voltage VG inputted through a terminal 5 to the gate of a TR M4 is set at a constant voltage which holds M4 in the intermediate state between the turned-on/off states, for this reason, the resistance of the section between the drain and source of M4 indicates the intermediate value between the minimum value at a turned-on time and the maximum value at a turned-off time. Consequently when an input data phiin is at the L level and a driving TR M1 is turned off, the L level is outputted to a first output terminal 3, since the resistance of the section between the drain and source of M4 connected to the section between the output terminal and a power source terminal 4 of the L level VS indicates a constant value, the output impedance can be suppressed to the extent around the resistance value of the section between the drain and source of M4. Thus even when the load indicates the capacitive impedance, the effect of the noise can be decreased.

Title: Apparatus for inspecting measuring leakage current
Inventor: WAKABAYASHI MASAHIRO
IPC: G01R31/02
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent an electric shock accident by outputting a detection signal at the time for a measuring AC output current value to exceed a specified current value, and cutting off the measuring current to an output terminal based on its detection signal. SOLUTION: When a voltage of about 6mV or more is inducted across a variable resistor 30 via an output shut-off unit 8, a voltage of an amplified signal differentially amplified by a differential amplifier 31 exceeds a reference voltage of a reference voltage source 32, and a comparator 33 outputs a detection signal. The detection signal operates a thyristor 37 to short-circuit a capacitor 35. Therefore, a load of a diode bridge becomes heavy, and sufficient operating current flows to coils 4C1, 4C2 of a circuit breaker 4. Thus, the breaker 4 is reset, movable contacts 4a1, 4a2 become non-contact state with fixed contacts 4b1, 4b2 to cut off an input to the apparatus of a commercial power source. In this manner, an electric shock accident can be effectively prevented.
