Title: Clutch-brake device for working machine
Inventor: NAGAI SHIGEO
IPC: A01D34/76
Filed: 1981-02-06
Abstract: PURPOSE:To surely prevent a trouble of engine stop in the above described device suitable for a power lawn mower, by decreasing a load applied to an engine when the engine is switched from its idling state to its clutch connected state. CONSTITUTION:In a state applied with a brake when a brake spring 29 is extended, a cam ball 28 is located in the deepest position of ball clamps 26, 27 to obtain a minimum distance between a cam plate cover 23 and cam plate 1. On the other hand, a lining plate 13 is pressed by a pusher plate 16 to contract a clutch spring 14, and a brake lining 15 is separated from a clutch disc 5. Ac- cordingly, an output shaft 4 and the disc 5 are raced even by driving an engine, and a rotary member 11 is not rotated, then a working blade (not shown) mounted to this rotary member stops standing still. On the contrary, if a control lever 24 is pulled to a direction A, the lining 15 is press attached to the disc 5 to rotate the working blade to a direction B.

Title: Transmission gear for mowing machine
Inventor: ISHIMARU TAKEYUKI
IPC: F16H7/12
Filed: 1990-01-26
Abstract: PURPOSE:To simplify and facilitate mounting and/or demounting work of a mowing device by providing the mowing machine side with a braking mechanism which is interlocked with the tensing/slackening mechanism of a transmission belt so that belt transmission is interrupted when the transmission belt is slackened. CONSTITUTION:A mowing device 5 is so actuated via a link mechanism 2 as to be lifted and/or lowered with respect to a running vehicle body. When a tensing/slackening mechanism is actuated to the tension side of a transmission belt 6, the brake of the transmission belt 6 by means of braking mechanism 8 is released, power is then transmission to the mowing device 5 from the side of a prime mover via a belt transmission mechanism 4. When the tensing/slackening mechanism 7 is actuated to the slackening side of the transmission belt 6, the transmission belt 6 is slackened, and the brake is concurrently applied to the transmission belt 6 by the braking mechanism 8 so that power transmission to the mowing device 5 is thereby interrupted. When the mowing device 5 is mounted on and/or demounted from the running vehicle body, no other actuation is required for mounting and/or demounting the braking mechanism 8 except actuation for mounting and/or demounting the link mechanism 2. Since the braking mechanism 8 is provided on the moving device 5 side, it is sufficient only to mount and/or demount the link mechanism 2, thereby making it possible to simplify actuation for mounting and/or demounting the mowing device 5 so as to facilitate the actions.

IPC: G03F7/06
Filed: 1982-02-03
Abstract: PURPOSE:To correct the image of a silver salt lithographic plate rapidly and exactly, and to obtain a correcting soln. superior in printing resistance of the corrected image, effective after oleophilicness giving treatment, and storable for a long term, by adding iodine or an inorg. iodine compd. CONSTITUTION:A viscosity raising agent, such as carboxymethyl cellulose, is added, when needed, to an aq. soln. of iodine or an inorg. iodine compd. such as KI, NaI, or ZnI2 in order to prevent spreading of a correcting soln. beyond a place necessary for correction. The correction soln. thus prepared may contain dye or pigment when needed, and in addition, glycerin, glycol, or a pH controller. As a result, correction effect does not depend on correction temps., an image can be corrected rapidly and exactly, and the correction soln. is retained effective for correction even after oleophilicness giving treatment. The corrected printing plate is good in printing resistance.

Thence, a protective film is formed by leaving scale lines by using a photographic printing method, after which scale lines are etched by a conventional method. A dissimilar color graduating treatment is applied on the etched parts by black chrome plating or the like, following to which the protective film is dissolved away. If necessary, the surface of the blank material is first immersed in an erosion resistant chemical such as ferric chloride and is roughened by this, after which the electrolyzing and succeeding treatments are executed.

Title: Screw compressor, and control method thereof
Inventor: MAEDA JUNJI
IPC: F04C28/08
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent reduction of discharge pressure even when used air quantity exceeds a rated value in the case where a discharge pressure set value is lowered by determining the number of the highest rotation of a motor in accordance with the discharge pressure set value in a compressor main body. SOLUTION: Compression air compressed to a specified pressure in a compressor main body 3 is discharged from discharge pipings 6. At this time, a pressure sensor 7 detects pressure of the compression air to be fed back to the number of rotation control device 8. The number of rotation control device 8 operates the operation number of rotation in accordance with used air quantity in a demanding apparatus, and an inverter 1 is controlled to control rotation of a motor 2. For a control range of the operation number of rotation in this case, the number of rotation number preliminarily set in the heighest number of rotation control device 9 based on a set pressure by a discharge pressure setting device 10 is taken as the upper limit.  In this constitution, in the case where it is set at a lower pressure than a rated pressure, air quantity exceeding rated air quantity can be obtained within a motor load capacity range. Discharge pressure can thus be prevented from lowering even when the rated air quantity is exceeded.

Filed: 1993-01-11
Abstract: PURPOSE: To produce nitrogen and ultra high purity oxygen with a simplified system without impeding a nitrogen producing efficiency by producing nitrogen and the ultra high purity oxygen through cryogenic rectification of supplied air and producing nitrogen in a single column system. CONSTITUTION: Supplied air 1 is initially separated to nitrogen enriched steam 30 and oxygen enriched liquid 2 by cryogenic rectification in a nitrogen purification column 100. The resultant steam 30 is condensed in a top condenser 150, and a portion of the liquid 2 is supplied to an upper portion of a first purification column 200 through the top condenser 150. While the liquid flows down through the column 200, light components of the liquid are separated therefrom by steam ascending from a bottom reboiler 250 to obtain oxygen concentrated liquid. The oxygen concentrated liquid is then vaporized in the reboiler 250 to produce oxygen concentrated steam which is passed to a second purification column 300 where heavy components of the steam is separated therefrom by a falling fluid to obtain ultra high purity oxygen steam.  The ultra high purity oxygen steam is condensed in a top condenser 350 to obtain ultra high purity oxygen liquid 35.
