Title: Winding method for thin steel plate having irregular thickness widthwise
Inventor: TSUMORI KENJI
IPC: B21C47/02
Filed: 1981-04-28
Abstract: PURPOSE:To wind the titled steel plate of high quality by winding the thin steel plate which is annealed after cold rolling and has irregular thickness widthwise in tension states of optimum areas in the beginning of winding and thereafter. CONSTITUTION:A thin steel plate which is annealed after cold rolling and has irregular thickness widthwise is treated with normal 2-10kg/mm.<2> winding tension from the beginning 23 of winding up to a position 24 which corresponds to length about 1/10-1/15 as long as the overall length of the steel plate, thus allowing the steel plate itself to serve as a coil internal surface reinforcing material. In this case, the number of laminated layers is small, so the flatness of the wound steel plate is not spoiled. Then, the winding tension of the steel plate is decreased according to a gradually decreasing type A or stepwise type B up to winding tension 21 which is <=2kg/mm.<2>, and the remaining steel plate is wound entirely, thus winding the thin steel plate completely at a point 25.

Title: Power unit mounting device containing liquid
Inventor: TABATA TOSHIYUKI
IPC: F16F13/10
Filed: 1984-04-02
Abstract: PURPOSE:To effectively damp vibration due to shaking by an engine, by setting the ratio of lengths of a pair of orifices to a value from 2.5-9 so that a frequency at which the damping force is maximum is made to fall in a low frequency range in which the shaking of the engine occures. CONSTITUTION:Diaphragms 4, 5 and partition plates 6, 7 which are secured, respectively to a base plate 1 on the power unit side and a base plate 2 on a vehicle side, define a first subchamber 8 and a second subchamber. A pair of orifices 15, 14 having substantially equal crosssectional areas and having lengths which are set at a ratio from 2.5-9, are formed in the partition plates 6, 7. As a result the mass of fluid in one orifice 14 having a longer length resonates in a lower frequency range to give a large damping force while the mass of fluid in the other orifice 15 having a shorter length resonates in a higher frequency range to give a damping force having the same magnitude as that of the former damping force, thereby it is possible to effectively damp vibration due to shaking by an engine.

Title: Vacuum valve
Inventor: UENO TADAO
IPC: F16K51/02
Filed: 1983-04-11
Abstract: PURPOSE:To make the vacuum condition of the entire apparatus not to be affected by opening a vacuum circuit, by providing one end of a pipe with a blocking portion of air flow including an air hole and a pore and providing a movable member adapted operable to open and shut the hole by a differential pressure in the pipe. CONSTITUTION:If a vacuum pump is connected at the side of the blocking portion of the pipe, since the pressure in the interior 4 of the pipe and that in the air hole 5 are the same, the movable member 8 is pushed away as far as it is stopped by the stopper 9 by the action of the spring 7. If, then, the rear end 3 of the pipe is opened to the air, the pressure in the pipe bore 4 becomes the atmospheric pressure and the movable member 8 is thereby caused to move in the direction as indicated by the arrow against the action of the spring 7. Then, since there only exists a pressure drop along the pore 6 due to the air flowing therethrough, the vacuum pressure on the pump side is kept considerably high. When the rear end 3 of the pipe is shut, the movable member 8 is pushed back by the spring 7 and the entire apparatus again recovers the desired degree of vacuum.

Title: Zooming system
Inventor: OTAKE YOSHITOMO
IPC: G02B7/10
Filed: 1987-03-18
Abstract: PURPOSE:To eliminate the unnaturalness of image plane variation in zooming by controlling the moving speed of a movable lens in optical-axis directions so that a view angle determined by the position of the movable lens varies almost linearly to a zooming time. CONSTITUTION:The plane developed shape of a cam groove 8 is so formed that a curve obtained by a curve showing the relation between the rotational angle theta and distance (a) of a cylindrical cam 7 by R in a theta direction is nearly circle, where R is the radius of the cylindrical cam 7 and theta is its rotational angle. Then when the movable concave lens L2 is moved by using this cam groove 8, the view angle alpha of a zoom lens is nearly in direct proportion to the rotational angle theta of the cylindrical cam 7, and consequently the view angle alphavaries almost nearly. Therefore, the unnaturalness of the size of an image plane in zooming is eliminated by controlling the moving speed of the movable lens in the optical-axis directions so that the view angle of the zoom lens varies almost linearly to the zooming time.

Abstract: PURPOSE:To improve production yield of a casting slab by determining a cutting length of the casting slab bottom based on measured values of a molten steel temp. and strong deoxidizing element, obtd. in the range of the molten steel from a tundish to a mold at the time till reaching to a steady casting state of the first heat. CONSTITUTION:The molten steel S is supplied into the tundish 3 from a ladle 1 through a long nozzle 2. At the time of opening a pouring hole 4, the temp. measurement of the molten steel is executed by a temp. measuring instrument 7 arranged at the tundish 3. Further, the molten steel sample is extracted by a sampler 8 for analysis. The casting slab bottom part, corresponding to the molten steel having <=20 deg.C over-heating degree of the molten steel and >=0.003% unsoluble A by the result of analysis is cut off. In this way, degrading ratio of the products is remarkably reduced and also the casting yield is improved.

Abstract: PURPOSE:To provide an effective differential pressure seal which obviates the generation of product quality deterioration and sheet crack by providing a sealing attachment along a guide roll provided to the boundary of a space region having a pressure difference and providing a port communicating with a suction means to the attachment. CONSTITUTION:A long-sized thin strip 1 is passed continuously through differential pressure chambers 4-6 in which the degrees of vacuum are successively increased from atm. P0 to P3.

The sealing attachment 3 which encloses the outside circumference of the guide roll 2 across nearly half the circumference is provided. The respective sealing surfaces S1, S2 each having a recessed arc shape are communicated via a piping P to a suction means to form apertures 3a, 3b to suck the air flowing in through the clearances formed between the sealing surfaces and the guide roll 2.

Title: Pulse output circuit
Inventor: IWASHIMA MAKOTO
IPC: H03K17/66
Filed: 1986-03-20
Abstract: PURPOSE:To stabilize the operation of an output side transistor (TR) by constituting a diode connected between bases of an input side TR and an output side TR by a TR of diode connection. CONSTITUTION:In case a pulse signal sent to an input terminal 1 is at high level, TRs Q1, Q2 and Q5 are conductive. If the TR Q2 is conductive, a TR Q3 of diode connection is conducted. Since a collector-base voltage of the TR Q3 is larger than a base voltage of the TR Q2, the base voltage of the TR Q4 is far lower than the base voltage of the TR Q2. Thus, the TR Q4 is surely nonconductive. On the other hand, in case a low level pulse is fed to the input terminal, the TRs Q1-Q3, Q5 are turned off and the TR Q4 is turned on. Thus, a large current pulse being the inversion of the input pulse is outputted at an output terminal 2.

Filed: 1978-05-31
Abstract: PURPOSE: To expand the range of detectable outside magnetic fields by disposing two thin-film magentic wires having uniaxial anisotropy of different asteroid magnetic fields in parallel and proximity and combining the outputs of these detecting elements.  
     CONSTITUTION: First and second magnetic detecting elements each composed of a core conductor 1 and a magnetic thin film 2 having a magnetization-difficulty axis in the axial direction and a magnetization easy axis in the circumferential direction is disposed parallel in priximity and exciting current 5 is applied in parallel with these. A coil 3 is commonly wound and output is drawn out from this. This makes  the magnitudes of the asteroid magnetic fields of the two magnetic detecting elements mutually different and since this causes the ranges RA, RB of the detectable  outside magnetic fields of both detecting elements to be combined to a range RC at  the time of detecting the existence of the outside magnetic field, the operation range  may be expanded and the field of application expanded.
