Title: Width variable mold device
Inventor: YOSHIDA TSUTOMU
IPC: B22D11/04
Filed: 1979-03-31
Abstract: PURPOSE:To make possible easy casting of the flat Al slabs of various width sizes by constituting the mold for continuous casting of Al slabs by mutually opposing long-side members and short-side members, moving the short-side members along the long-side members and curving the central parts of the long-side members to a broad width. CONSTITUTION:The long-side members 2a, 2b of the mold for continuous casting are movably mounted by means of the oblong holes 3 and bolts 4 provided to a water-cooled outer flask 1 to make possible the changing of the thickness of the slab to be cast. The short-side members 5a, 5b of the mold are so mounted as to permit changing of the width of the slab to various sizes by means of the plural bolt holes 8 pierced to the long-side members 2a, 2b and bolts 7. In addition, the inside surfaces 15a, 15b of the long-side members 2a, 2b are so curved as to widen the spacing in the central part. The use of this mold makes possible the casting of the slabs of Al or Al alloy of large shrinkage on cooling of various thicknesses and widths in the form that the both surfaces are parallel, with one set of the mold, thereby considerably improving productivity.

Title: Method for liquefying coal
Inventor: HAYAKAWA KEIICHI
IPC: C10G1/06
Filed: 1988-02-22
Abstract: PURPOSE:To contrive a lighter fraction and higher quality of products in relatively simple means and facilitate operation of a coal liquefaction process, by treating the total amount of liquefied oil other than light oils taken out in the liquefaction process in a solvent hydrogenation process. CONSTITUTION:A coal liquefaction product is distilled to carry out solid-liquid separation. Light oils are removed from the resultant distillate and the total residual amount is introduced into a solvent hydrogenation process to carry out hydrogenation while controlling hydrogenation depth. Light oils are then distilled from the above-mentioned hydrogenation product by atmospheric distillation and the total amount of the bottom liquid of a distillation column as a solvent is recycled to the coal liquefaction process. Furthermore, preferred conditions of the solvent hydrogenation are 300-400 deg.C reaction temperature and 0.5-2.0hr reaction time under 80-200atm. hydrogen pressure in the presence of an Ni-Mo/Al2O3 catalyst.

Filed: 1983-03-11
Abstract: PURPOSE:To prevent liquid toner from being leaked and to use a normal liquid feeding pump to reduce the cost by forming a leakage preventing space on the external peripheral surface of an opening of a mask on a liquid toner developing head. CONSTITUTION:A bending part 2d is formed close to the external end surface 2b of the opening part of the external peripheral surface of the mask 2. The angle alpha of a photosensitive material 3 on the external peripheral surface 2c is 90 deg. and the angle beta between the other part of the external peripheral surface 2c and the material 3 is about 5 deg.. Since the interval (e) is about 1mm., the leakage preventing space 8 is formed between the surface 2c and the material 3. Even if the liquid toner 5 fed by a pump 6a is leaked from the space between the surface 2b and the material 3, capillary phenomenon is not generated because the space 8 is wide, so that the leached toner 5 is not leaked moreover.

Title: Forced-circulation steam generator
Inventor: SHIDA TOUICHI
IPC: F22B35/08
Filed: 1978-04-05
Abstract: PURPOSE: To prevent pump cavitation by using a pressure detective device to make circulating flow run back at sudden pressure down, which is incorporated in a steam generator.  
     CONSTITUTION: A pressure detector 25 is used to detect pressur in the container 1 of a pile and puts the output signal into a fuction generator 26. The function generator 26 sends a signal of saturated temperature corresponding to the inputted pressure. A temperature detector 27 detects the temperature of circulating water on the suction side 10 of the circulation pump 9 and puts out a signal corresponding to the temperature. An adder 28 finds a difference between the output signal of the function generator 26 and that of the temperature detector 27 and puts out the  results to an alarm setter 29. When the difference, the signal from the adder 28, is  lower than a preset temperature difference, the alarm setter 29 puts out a signal C  to make circulation run back against potential cavitation.

IPC: H04N3/16
Filed: 1986-02-25
Abstract: PURPOSE:To set a fall equivalent to a flyback time at about zero by forming sawtooth waves by a digital circuit without using an analog circuit. CONSTITUTION:An n-bit counter circuit 11 defines the fall or rise of a vertical synchronizing signal separated from a synthetic video signal as a reset signal.

Abstract: PROBLEM TO BE SOLVED: To form an image of a puncture needle by performing MTI processing related to two echo signals having the packet length obtained by ultrasonic wave transmission/reception of two times per a single sound ray. SOLUTION: A transmission/reception frequency per a single sound ray in a Doppler mode is set to 2 so that a puncture needle 8 vibrating by actuating the driving part 22 is punctured by aiming at an interest region in a subject 4. When a needle member of the puncture needle 8 enters of a visual field to pick up an ultrasonic wave image, a Doppler signal of an echo from the needle member is generated, so that a CFM image and a power Doppler image of the needle member are generated by a Doppler processing part 12 on the basis of this Dopper signal. That is, MTI processing is performed on the basis of two echo received signals p1, p2 on the same sound ray obtained by ultrasonic wave transmission/reception of the first time and the second time.  Therefore, a position of the needle member can be always monitored by detecting a movement on the basis of a time phase difference between data, for example, data d1 and d2 in the same depth position in the echo received signals p1 and p2.
