Title: Foot shoe plate for continuous casting
Inventor: SHIRAISHI SHINJI
IPC: B22D11/128
Filed: 1980-07-22
Abstract: PURPOSE:To prevent blocking of injection holes and lengthen life of the plate by connecting plural recessed parts for cooling water injection on the surface of the plate with a vertical groove and thereby discharging flux in the recessed parts smoothly. CONSTITUTION:A cooling box 13 that supplies cooling water to injection holes 11 and cools the plate 4 itself is fitted on the back 4b of a foot shoe plate, and the plate is installed directly below the mold. It injects cooling water to the ingot from each injection hole 11 while moving vertically in a both with the mold and mold shower. At this time, molten flux on the surface of ingot is solidified and crushed to grains, and a part of them falls into recessed parts 10 of the plate 4. Since each recessed part 10 is connected with other recessed parts 10 below by a groove, the flux is washed down with water injected from injection holes 11, and discharged without staying in the recessed parts 10.

Title: Catalyst for dehydrogenation of cyclohexanol
Inventor: SAITO MASAHIRO
IPC: C07C45/29
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To enable a high catalytic activity to be maintained for a long time in the dehydrogenation of cyclohexanol by forming a catalyst for the dehydrogenation of cyclohexanol of copper oxide, zinc oxide and magnesium aluminate. SOLUTION: The catalyst for the dehydrogenation of cyclohexanol is composed of copper oxide, zinc oxide and magnesium aluminate. When the gross weight of the catalyst is given as 100 wt.%, the ratio of the copper oxide, zinc oxide and magnesium aluminate is set to be 20-60 wt.%, 30-70 wt.% and 0.1-10 wt.% respectively. When these components are set at the ratio other than described, the degree of the dehydrogenation activity of the cyclohexanol and the stability of the activity over time are insufficient. The catalyst is manufactured by producing a precursor sediment and cleaning/drying it and further baking it. Further, a water-soluble salt such as a nitrate or a sulfate can be used as a raw material for copper, zinc, magnesium or aluminum which are the components of the catalyst.

Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To facilitate the adjustment of action amount in the case of separating a toner removing member and a receiving member by separating them with each cleaning unit altogether. SOLUTION: In addition to a blade 2121, a seal 2122 for shielding space between the cleaning unit 212 and the surface of a transfer belt 207 so that toner scraped from the surface of the belt 207 by the blade 2121 may not be scattered to the outside of the unit is housed in the cleaning unit 212. The cleaning unit 212 is provided rotatably by a supporting shaft 2125, and supported by a pressing lever 2123. When a pressing cam 2126 is driven by a motor, etc., and rotated, it comes into contact with and separates from the lever 2123 so as to move an abutting part between the lever 2123 and the cleaning unit 212. Thus, the blade 2121 and the seal 2122 are separated from the belt 207 or abut on the surface of the belt 207 with the cleaning unit 212 altogether.

Title: Zoom lens of rear focus type
Inventor: ENDO HIROSHI
IPC: G02B15/22
Filed: 1987-04-24
Abstract: PURPOSE:To decrease the sensitivity difference at a wide angle end and telephoto end and to facilitate mechanical control of lens groups by increasing the respective spacings between the 1st and 2nd groups and between the 3rd and 4th groups at the time of varying powers from the wide angle end to the telephoto end with 5-groups constitution having positive, negative, positive, negative, and positive refracting power successively from an object side. CONSTITUTION:The 1st group is moved to the object side to decrease the overall length of the lens at the wide angle end and to increase the overall length at the telephoto end so that the increase in the diameter of the front lens is prevented and various aberrations are corrected by increasing the telephoto ratio on the telephoto side at the time of varying powers from the wide angle end to the telephoto end with the constitution of 1st-5th groups having the positive, negative, positive, negative, and positive refracting powers from the object side. The variable power action is partially born by the 3rd group by moving the 2nd group to the image plane side and the 3rd group to the object side and the various aberrations are corrected by moving the 4th group to the image plane side. the fluctuations of the various aberrations are negated with each other by reversing the refracting powers of the respective groups from each other and the focusing operation is executed by the 3rd group. The sensitivity difference at the wide angle end and the telephoto end is thereby decreased and the mechanical control of the respective lens groups is facilitated.

IPC: B66C1/34
Filed: 1994-04-15
Abstract: PURPOSE:To provide a hook device for cargo handling which is constituted to be light and excellent in workability and automatically release a cargo string. CONSTITUTION:A hook device 1 for cargo handling comprises a moving suspension tool 2 and a control tool 3, manufactured independently and making a pair, which are intercoupled through a traction wire 4. Since when a solenoid 15 is energized for excitation, a moving core 14 is moved backward to pull a traction wire 4 (4A), the tip part of a hook stopper 9 is rocked upward centering around a pin 8. As a result, since the lock protrusion body 9A of the hook stopper 9 engaged with the lock part 12B of a hook 12 is separated away from a hook, the hook port 12 is rotated around a support pin 11 to a state that a hook 12A is brought into an up state, a cargo string L is naturally released. By rotating the hook until the hook port 12A is brought into an up state, the hook stopper 9 is caused to rebound through the force of a rebound material 10 and the lock protrusion body 9A is engaged with the lock part 12B of the hook 12, whereby a cargo can be lifted. A control tool 3 is disposed in a position separated a way from the hook and the hook stopper 9 is remotely controlled.

Title: Method and system for measuring position on road and apparatus suitable for the same
Inventor: SEKINE CHOGO
IPC: G08G1/0969
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To always measure a correct position on a moving body. SOLUTION: A plurality of leaked cables 12 are arranged parallel along a road, and transmitters 10 adjacent to each other transmit pulse signals for measuring distance to the corresponding leaked cables 12 synchronizing each other and at timings different from each other. A measuring device 16 is carried on a moving object such as vehicle 14 running on the road and receives a leaked radiation of the pulse signal for the measurement from the leaked cables 12. Since the pulse signal for measuring the distance received by the measuring device 16 reflects the required transmission time for propagation on the leaked cables 12 and the difference therebetween in addition to a difference in transmission time between the transmitters 10, if the interval D between the transmitters 10 is known in advance, the relative position L of the vehicle 14 can be known.  Identification information of the transmitters 10 is transmitted through the leaked cables 12 from the transmitters 10, thereby enabling the absolute position thereof to be known as well.
