Title: Hydrogenation treatment of heavy oil and device for hydrogenation treatment
Inventor: AZUMA HIDEHIRO
IPC: C10G45/06
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for hydrogenating a heavy oil, enabling to stably and efficiently hydrogenate the heavy oil over a long period without depositing cokes by hydrogenating the heavy oil in fixed bed type reaction towers and subsequently hydrogenating the prehydrogenated oil together with a new raw material oil in a suspension bed type reaction tower. SOLUTION: This method for hydrogenating a heavy oil comprises hydrogenating a heavy oil (e.g. vacuum gas oil, crude oil, atmospheric pressure or reduced pressure distillation residual oil) as a raw material oil in fixed bed type reaction towers 1, 2, 3 filled with hydrogenation treatment catalysts, and subsequently hydrogenating the prehydrogenated heavy oil (A) together with a new raw material oil (B) (preferably containing vanadium and nickel in a total content of <=50ppm) in a suspension bed type reaction tower 4 filled with a hydrogenation treatment catalyst in a suspension state. The component B is used in an amount of 0.5-50vol.% based on that of the component A in the reaction in the suspension bed type reaction tower.

Abstract: PURPOSE:To prevent swings of a position light column around a pair of electrodes in a bulb, reduce unevenness in the brightness, and stabilize the light output by locating the two ends in axial direction of an external electrode approx. identical to the inner ends of the electrodes. CONSTITUTION:A pair of cold cathodes 23a, 23b are airtightly mounted sealedly at the two ends in axial direction of a cylindrical bulb 22 made of glass in such an arrangement as facing together within the bulb 22. An external electrode 25 in the form of a band having a certain width is adhered axially in a specified place on the peripheral surface of the bulb 22, wherein the two ends in axial direction of the external electrode 25 shall be located approx. identical to the inner ends of the cold cathodes 23a, 23b. Thus the electrodes 23a, 23b themselves are free from affection of the drawing effect of the positive light column alphadue to the external electrode 25, and the place where positive light column alphais generated will be unchanged. This prevents swings of the positive light column alpha around the electrodes 23a, 23b to accomplish reduced unevenness in the brightness and stabilized output of light emission.

Title: Monitoring system for optical transmission line
Inventor: MIYAUCHI AKIRA
IPC: H04B10/07
Filed: 1981-07-10
Abstract: PURPOSE:To reduce the number of cables and to monitor surely troubles of transmission lines, by transmitting a main signal and a monitoring pilot signal through the same optical fiber in the optical wavelength-division multiplex system. CONSTITUTION:A terminal station 19 transmits a main signal lambda1 and a pilot signal lambda2 to a repeater 29 through an optical fiber 119 in the optical wavelength- division multiplex system and receives an optical signal, where a main signal lambda3 and a pilot signal lambda4 are multiplexed, from the repeater 29. Similarly, a terminal station 21 receives the main signal lambda1 and the pilot signal lambda2 from a repeater 30 and transmits the main signal lambda3 and the pilot signal lambda4. Since main signals and pilot signals are carried through one optical fiber 120 between repeaters 29 and 30, the number of cables is reduced considerably. If a trouble occurs on the optical transmission line for a main signal system, information indicating the break of pilot signals is always carried; and thus, troubles are monitored more surely than troubles in conventional systems.

Title: Heat exchanger
Inventor: KIDO OSAO
IPC: F28F1/32
Filed: 1984-05-28
Abstract: PURPOSE:To improve heat transfer coefficient by a method wherein the heat exchanger is constituted of a number of parallel small fin pieces and a heat medium pipe penetrating through the small fin pieces while at least one end of the inlet side or the outlet side of airflow of the small fin pieces are provided with a number of twisted pieces separately. CONSTITUTION:The small fin pieces 3, provided with the twisted pieces 4, are arranged on the heat medium pipe 2 in parallel with predetermined pitches. The number of twisted pieces 4, provided on the small fin pieces 3, are arranged separately on both ends of inlet and outlet sides of airflow so that the directions thereof coincide with the direction of the airflow A. The heat medium flows through the heat medium pipe 2 and heat exchange between the heat medium and air is effected utilizing the heat medium pipe 2 and the small fin pieces 3 as heat transfer surfaces since the air flows between the small fin pieces 3 on the outside of the pipe 2. In this case, eddy-like disturbance is generated in the airflow, flowing between the small fin pieces 3, and turbulent flow promoting effect may be obtained remarkably thereby improving the heat transfer coefficient.

IPC: G11B5/55
Filed: 1982-06-25
Abstract: PURPOSE:To have quick program searching, by shifting a magnetic head only in a ragne of a recorded track in a reproduction mode to prevent the shift of a magnetic head to the unrecorded track part and jsut by shifting the magnetic head only toward the inner circumference of a magnetic disk even in case a recording track is consecutively recorded. CONSTITUTION:A clutch is pushed down in an initial state, and terminals C and D are not conductive. At the same time, a detector 14 for utmost outer circumference track has a contact with a pawl 11c of a clutch 11 to make terminals A and B conduct. Thus it is impossible to shift a magnetic head 8 toward the outer circumference. Then the clutch 15 is pushed up to fit a counter 2 at an instant when a projected part 15a is coincident with a depressed part 2a after a motor 4 is turned consecutively. At the same time, the terminals C and D conduct to stop the motor 4, and the head 8 is fed up to the final recording track of a magnetic sheet 1a. When the reproduction is carried out in the initial state, the head 8 is not shifted toward the outer circumference of a disk but shifted toward the inner circumferenc since the terminals A and B conduct. Then the head 8 is stopped when the terminals C and D conduct and never shifted toward more inner circumference than the position of the corresponding track.

Filed: 1994-04-25
Abstract: PURPOSE:To eliminate the labor for assembling a hanger rack, and to fold a hunger rack for housing after using it by connecting three rectangular frame bodies in series so as to be freely turned. CONSTITUTION:A frame body A is formed of frames a1-a6, and the frame a1, the frame a5 or the frame a6 work as a supporting bar for locking a hanger bar, and the frames a5, a6 work as a reinforcement. Frame bodies A, B, C are connected by hinges h1, h2, h3, h4 freely to be turned. A framework for rack, which is formed by connecting the frame body A and the frame body C to the frame body B through the hinges h1-h4 freely to be turned, is used. When this framework for rack is not used, the frame body A and the frame body C are turned for folding around the frame body B so as to downsize the whole. Assembling of a rack can be quickly performed by one person by using a framework for rack. When the framework for rack is not used as a rack, since it can be easily housed in the flat condition, workability is improved and the housing space is reduced.
