Title: Roll
Inventor: ONO SHINICHI
IPC: B21B13/14
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To effectively relax a stress concentration to the barrel/shoulder part regardless of the grinding quantity of a roll surface by forming a groove for relaxing the stress at least on a roll side face part on the one side along the peripheral direction, and arranging a spacer for reinforcement in the groove. SOLUTION: The groove 6 is formed over the whole periphery of the roll side face part 1b. The ring shape spacer 7 for reinforcement is arranged and fixed by shrink fit in the groove 6. When rolling by using an intermediate roll 1 like this, the stress caused by rolling down is concentratively applied to a roll barrel/shoulder part 1a. This load is transmitted to the inside of the roll, and the outer periphery side of the groove 6 is elastically deformed. At that time, since the elastic deformation of the roll 1 is held back by the tip part side of the spacer 7 for reinforcement, the tip part of the spacer 7 for reinforcement becomes a fulcrum, and the outer periphery side wall part of the groove 6 is bent and deformed. This deformation is allowed until the outer periphery side wall face of the groove 6 is bent and comes into contact with the spacer 7 for reinforcement without a gap.  By this bending deformation, the stress to be applied to the barrel shoulder part 1a of the roll 1 is relaxed without a concentration.

Title: Vibro-isolating structure for internal pump
Inventor: MIYANO HIROSHI
IPC: F04D29/66
Filed: 1983-06-02
Abstract: PURPOSE:To aim at improvements in vibration resistance and earthquake-proofness during operation, by installing a contact part, having such a size as making its outer diameter contacting an inner circumference of the large diametral part of a nozzle so as to be equalized to the nozzle's large diametral part inner diameter in time of operating a nuclear power reactor, projectingly on the outer circumference of a sleeve part. CONSTITUTION:An upper end of a sleeve part 8a is joined to a nozzle 6 via a weld part 9, while a ring contact part 12 projectingly installed on a lower end part outer circumference of the sleeve part 8a contacts an inner circumferential surface of the lower end part of the nozzle 6. And, as for relations between the contact part 12 of the sleeve 8a and the nozzle 6, supposing an inner diameter of the nozzle 6 in time of indoor temperature is set down as D1, since the nozzle 6 in time of operating a nuclear power reactor is heated to a temperature of about 180 deg., the inner diameter, as shown in a broken line, extends wide to D2. Therefore, even in such a case, the outer diameter of the contact part 12 is produced to make it equal to D2 so as to cause an internal pump (not shown herein) to be supported with two points of the weld part 9 and the contact part 12. With this constitution, vibration resistance and earthquake-proofness during operation of the reactor are well improved.

Title: Electrifying mechanism for electrophotographic printer
Inventor: WATANABE AKIO
IPC: G03G15/02
Filed: 1987-04-21
Abstract: PURPOSE:To prevent a variance of the surface potential of a photosensitive drum by varying a current flowing through a grid of an electrifier, in the first rotation and the second rotation and thereafter, based on an output of a rotation detecting sensor of the photosensitive drum. CONSTITUTION:By a printing signal 1, a constant-current driving circuit 2 allows a current to flow from a discharge electrode 3a, and a rotation control part 4 rotates an OPC drum (photosensitive drum) 5 and starts a timer 6. The timer 6 outputs a 'High' level only when the OPC drum 5 makes one rotation, by which a high voltage transistor 8 becomes OFF through an inverter 7. Therefore, no current flows to a grid 3c, and a current flowing to the OPC drum 5 increases. When an output of the timer 6 becomes a 'Low' level, the high voltage transistor 8 becomes ON, a varistor current flows by a varistor 10 and a resistance 11, a current flows to the grid 3c, and the current flowing to the OPC drum 5 decreases. In such a way, the OPC drum 5 is electrified a great deal in first rotation, and electrified a little in the second rotation and thereafter, by which a variance of the surface potential of the OPC drum is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a side-ditch block and a method of manufacturing the side-ditch block preventing an intersection from being flooded when it rains heavily by increasing drainage capacity at each corner part of the intersection. SOLUTION: A plastic bellows pipe 13a is built in a block forming form 30 with a bend part 11 formed on one end side. A linear inner frame 34 is further built in continuously with the bellows pipe 13a, and a drain hole frame 30d is further built in downward between the inner frame 34 and the block forming form 30. In this state, ready-mixed concrete 35 is poured in the form 30 and fixed by a top frame 30f. After solidification, the top frame 30f is removed, and a side frame 30a, a frame 30b with a hole, the inner frame 34 are disintegrated, while the bellows pipe 13a is left as it is. In this way, a water passage 12 with the bend part 11 inside, and a drain hole 16 between the water passage 12 and the upper face of a block body 10 are formed.  As a result, when this block is installed butting the corner part of an intersection, water is drained into the side-ditch block also at the corner (four corner) parts of the intersection, so that drainage is never insufficient even when it rains heavily.
