Title: Closed compressor
Inventor: SAWAI SATOSHI
IPC: F04B27/047
Filed: 1979-04-16
Abstract: PURPOSE: To promote the result coefficient of a closed compressor by filling the interior of the closed casing with an atmosphere of exhaust gas of a high pressure for preventing suction gas from overheating.  
     CONSTITUTION: When an electric motor 7 is driven to rotate a revolution shaft 8, an annular groove 10 of a body of rotation 9 is eccentrically rotated in accordance with the rotation of the revolution shaft, and consequently, each piston 12 in each cylinder 5 is successively reciprocated at a fixed phase difference. Among cylinders 5, into each in a suction stroke, suction gas g 1  from a suction gas inlet 20 is sucked through a suction gas passage 21 and an annular passage 22, while from each in a compression stroke, exhaust gas g 2  is exhausted to an annular space 23 through an exhaust port 27. The exhaust gas g 2 , after filling a casing 1, is conducted into an electric motor chamber 6 via a passage hole 24, and after cooling the electric motor 7, brought out through an exhaust gas outlet 25. Since the suction gas g 1  is sucked into each cylinder via the suction gas passage 21 and the annular passage 22, the suction gas g 1  is prevented from overheating.

IPC: G03G15/20
Filed: 1997-02-15
Abstract: PROBLEM TO BE SOLVED: To provide an endless belt driving device which an surely prevent a belt from laterally shifting in a simple and inexpensive constitution. SOLUTION: This endless belt driving device is provided with a moving body 5, which can be rotated and slid freely, a tapered member 8, on which the moving body 5, when it is slid, rides, and a moving body shaft 9, which supports the moving body 5 so that it is inclined according to the riding quantity when the moving body 5 rides on the (taper section 8a of) the tapered member 8. When the endless belt 1 is about to shift, the end section of the moving body 5 is inclined while riding on the tapered member 8 due to the friction force between the endless belt 1 and the moving body 5. The endless belt 1 is forced to return in the direction to reduce the quantity of shift. As a result, the endless belt 1 is stabilized and circularly run at a position where the shifting force of the endless belt 1 in the initial state and the returning force due to the inclination of the moving body 5 are balanced.

IPC: G05B19/4061
Filed: 1984-03-15
Abstract: PURPOSE:To reduce the cost of the titled detector with reduction of number of cables by using two relays to detect the minus and plus sides respectively of the working limit of each axis of a robot. CONSTITUTION:Each axis of a multi-joint robot contains a cam 12 fixed at an active part and limit switches 13 and 14 provided at a fixed side to detect the limits of the minus and plus sides. The cam 12 detects each limit. Limit switches LS1A-LS5A and LS1B-LS5B are connected in series at both sides of each axis. Then relays CRA and CRB are connected to those limit switches. Thus the operation is impossible with push-buttons of even numbers of an operation box when the relay CRA works, and only push-buttons of odd numbers are operable. These operations of push-buttons are reversed when the relay CRB is active, and the movement of a motion axis is stopped.

Abstract: PURPOSE:To make possible the control of the sectional shape of the rolled material without frequently interchanging the roll, by giving the horizontal bend to the intermediate rolls of the rolling mill so as to make narrow the gap of intermediate rolls at the middle part, on purpose to adjust the deflection of the work roll. CONSTITUTION:A couple of upper and lower work rolls 2, 3, a couple of upper and lower backup rolls 10, 11, on outside of work rolls 2, 3, and at least a couple of horizontal intermediate rolls 6, 7, between work rolls 2, 3, and backup rolls 10, 11, are arranged. The rolling load impressed on the backup rolls 10, 11, is transmitted to the work rolls 2, 3, through the intermediate rolls 6, 7, and compresses the rolled material 14. Hereupon, by actuating the cylinder-piston mechanisms 16, 17, 18, 19, the intermeidate rolls 6, 7, cause the horizontal elastic deformation, and displace from the solid lined position to the dotted lined position; hereby, the roll gap of the intermediate rolls 6, 7, is made narrower at the middle part than that on both sides. As a result, the roll 2 is deflected into a downward projecting arc shape, and the rolled material 14 receives the compression strongly at its middle part.

Abstract: PURPOSE:To prepare the title compsn. excellent in the light resistance and low-temp. solubility by compounding a lithium salt of C.I. Acid Red 37, a water- sol. org. solvent, and water, and keeping the inorg. salt content in the resulting compsn. at a specified low level. CONSTITUTION:A lithium salt of C.I. Acid Red 37 (obtd. by washing a commercially available C.I. Acid Red 37 dye in an aq. HCl soln. and neutralizing it with LiOH soln.), a water-sol. org. solvent (e.g. ethylene glycol or methyl carbitol), and water are compounded in such a manner that the inorg. salt content in the resulting compsn. is kept under 0.5wt.%, giving a red ink compsn. The commercially available C.I. Acid Red 37 dye, though light-resistant, has a poor solubility, which is improved by converting the dye into a lithium salt. In addition, keeping the inorg. salts contents, one reason for dye precipitation, under 0.5wt.% contributes to give a red ink compsn. excellent in the low-temp. solubility.
