Title: Production of hydroxydiphenylamine compound
Inventor: HASHIMOTO KIYOYASU
IPC: C07C215/82
Filed: 1983-05-10
Abstract: PURPOSE:To obtain the titled compound useful as an intermediate of organic pigment, in high yield and purity, by diazotizing an aminodiphenylamine compound, and heating in a dilute acid. CONSTITUTION:The objective hydroxydiphenylamine compound can be prepared by diazotizing an aminodiphenylamine compound, and heating in a dilute acid. The diazotization is preferably carried out at <=15 deg.C, and the dilute acid is a 1-40% solution of an inorganic acid (e.g. sulfuric acid) excluding hydrogen halide. The substitution of the diazonium group with hydroxyl group can be achieved by heating the diazonium compound in a 1-30% dilute solution of the acid at 80-110 deg.C. Addition of a copper compound such as copper sulfate, copper acetate, etc., a salt such as sodium phosphate, or a water-insoluble solvent such as toluene, xylene, etc. to the reaction system is extremely effective to improve the selectivity and yield. The amount of the copper compound and the salt is 1-50wt%, and that of the water-insoluble solvent is 3-40wt% of the reaction solvent.

Title: Hydraulic shovel
Inventor: YAMAZAKI HIROAKI
IPC: E02F3/43
Filed: 1995-03-15
Abstract: PURPOSE: To prevent a shovel from getting in contact with a buried material ana making smooth a leveling worm,by restricting the retracting motion of the arm within the turning range of the vertical basic posture of the arm and also restricting the pushing motion of the arm in the backward turning range of the basic posture. CONSTITUTION: The working depth of a working part is operated on the basis of a detected value of a posture-detecting sensor and the operated working depth is compared with a limit depth preset in advance. In this time, the retracting actuation and the pushing actuation of the arm 6 are restricted in the turning range or the basic posture of the arm 6. That is, the working depth is limitted in the backward turning range in which the working depth varies to the deeper side, even during the pushing actuation of the arm 6. Accordingly, inconvenient of contact with buried materials during the pushing work of the arm 6 is eliminated and hence, an accurate pushing leveling work can be carried out by making use of the depth-restricting function. And further, the actuation is restricted against the motion varying to the deeper working side.  In this way, the control is simplified and the operating speed can be increased in the control part.

Filed: 1986-04-11
Abstract: PURPOSE:To eliminate the occurrence of foreign matters and abnormal sounds due to a wear without a friction loss by constituting the attraction and repulsion of a magnetic force as a pressurization means. CONSTITUTION:A magnet 10 is fixed to a carriage 3 together with a pair of magnetic plates 9, forms a frame 8 having a magnetism and a magnetic circuit and gives a pressurization in the direction of an arrow 12 to a pinion 4. Here, by driving a step motor 6, the pinion 4 and a rack 5 shift the carriage 3 in the direction of an arrow 11. At such a time, the magnet 10 and the magnetic plate 9 fixed to the carriage 3 are also shifted, since the frame 8 and the magnetic path are formed, the pressurization always works in the direction of the arrow 12, and for such a reason, the rack 5 and the pinion 4 are contacted under pressure, a play does not exist at the rotation of the step motor 6 and the mesh of the rack 5 and the rotation of the step motor 6 is correctly transmitted. By the strength of the magnetic force of the magnet 10, the strength of the pressure can be also changed.

Title: Label printer
Inventor: SUGIMOTO KAZUAKI
IPC: B65C9/18
Filed: 1990-03-30
Abstract: PURPOSE:To make trial hitting unnecessary by preventing positional slip of a support paper from happening when label issue is paused, and improve the handling easiness by a method wherein by pressing a separation roller to a platen roller by an elastic body to energize a separation frame, the separation roller is follow-turned by the platen roller through a support paper. CONSTITUTION:As a first torsion spring 68 energizes a separation roller 64 upward by the elastic force through a separation frame 62, a separation roller 64 is pressed to a platen roller 14 from the bottom, and is follow-turned by the platen roller 14 through a support paper C. When label issue is paused, the motion of a paper feeding device is stopped, however, as the separation roller 64 is follow-turned by the platen roller 14 while being pressed to the platen roller 14, the rotation of the separation roller 64 is stopped at the same time with stop of the platen roller 14. For this reason, the separation roller 64 does not continue its rotation, and the support paper C is not moved by the separation roller 64. Therefore, the support paper C is prevented from slipping from a specified stop position.
