Title: Straightening roll and its manufacture
Inventor: MORIGUCHI YOSHIHIKO
IPC: B21D3/02
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of cracks in the boundary part between a high-hard built-up layer which is formed on the surface of a straightening roll and a base metal. SOLUTION: This roll is a roll on which a groove 3 for forming a wear- resisting built-up layer 2 is formed into a concave shape in the direction of the rotation of rolls, especially into a circular-arc shape and the distance between the middle part where shearing stress is most apt to generate and the surface of the roll is made large and the boundary surface between the wear- resisting built-up layer 2 and the base metal 1 is enlarged. In this way, internal shearing stress which is generated on the boundary is reduced and, even when high specific pressure load is applied, the occurrence of cracks on the boundary surface is decreased.

On the other hand, inputted video signals are supplied to a horizontal synchronizing separator circuit 3, and horizontal synchronizing signals are seaparated there. Horizontal synchoronizing signals are delayed in a variable delay circuit 11 of the next stage by the same quantity of delay generated in a Y.C separating circuit 2 and applied to a PAL control signal generating circuit 10. Consequently, various kinds of control signals made in the PAL control signal generating circuit 10 can be corrected to become correct positional relation with luminance signals Y and carrier chrominance signals C.

Title: Maximum injection amount controller of diesel engine
Inventor: KIZAKI KANJI
IPC: F02D23/02
Filed: 1991-06-06
Abstract: PURPOSE:To obtain adequate maximum injection amount and good acceleration performance when change from atmospheric pressure to suction air pressure is done and detected. CONSTITUTION:The use of a suction air communicating passage 65 which is communicated to a suction port 53 and an atmospheric communicating passage 67 is changed over by VSV66 selectively, and suction air pressure and atmospheric pressure are detected by one pressure sensor 74 selectively. The maximum injection amount of a diesel engine 2 is controlled in accordance with the detected value. During the predetermined period of time after the detection with the pressure sensor 74 is changed over from atmospheric pressure to suction air pressure by the change-over of VSV66, estimated suction air pressure is calculated based on the number of revolutions of engine, opening degree of accelerator, and the newest result of detection of atmospheric pressure by the pressure sensor 74. The maximum injection amount is compensated and calculated based on the estimated suction air pressure. Thus, improper detected output of the pressure sensor 74 is complemented by the estimated suction air pressure when change from atmospheric pressure to suction air pressure is done and detected. It is used in the calculation of the maximum injection amount.

Title: Atm communication network
Inventor: HASEGAWA HARUHISA
IPC: H04Q3/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To generate input load rate information as a control information of output rate without requiring any complicated calculation for an exchange to be observed by operating an input load rate through the exchange to be observed, reporting it to an exchange for controlling an output rate, and reporting the larger value to the upstream side when there is input load rate information from the other exchange. SOLUTION: Exchanges 1-1, 1-2, 2-1 and 202 respectively find the input load rates on relevant VP links from input rate/VP link capacitances. Then, the exchange 2-2 reports the input load rate of VP link 3-4 to the exchange 2-1. Further, the exchange 2-1 reports any larger one of input load rates at a VP link 3-3 and from the exchange 2-2 to the exchanges 1-1 and 1-2. Then, the exchange 1-1 defines any larger one of the input load rate at the VP link 3-1 and the input load rate reported from the exchange 2-1 as the total input load rate of VC route 4-1 and holds its value.

Title: Under mirror device for vehicle
Inventor: YAMAUCHI NOBUHIRO
IPC: B60R1/06
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To move a mirror structure between the use condition and the non-use condition by having a first engaging unit, which is formed between an arm and a driving roller and which engages the arm and the driving roller in the direction nearly crossing the rotating direction of the driving roller. SOLUTION: When a motor 7 is operated, a rotary shaft 6 is rotated through an engagement of a warm gear 72 and a warm wheel gear 61. A driving roller is rotated in relation to an arm 4 by the rotation of the rotary shaft 6, and the torque of the driving roller is transmitted to the arm 4 by the friction slide- contact of a cam surface of the arm 4 with the driving roller, and the arm 4 is moved in the longitudinal direction in relation to the driving roller. At this stage, the movement of the arm 4 in the longitudinal direction is guided by a driven roller 9 and an auxiliary roller. With this structure, a movable member 31 is moved in the three-dimensional direction because of the shape of the arm 4, and non-use condition A and use-condition B are switched.
