Inventor: ITO HIROSHI
IPC: C09D11/38
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To obtain an aqueous ink composition which is excellent in both setting stability and storage stability by dispersing, in an aqueous medium, a surface-modified pigment which is prepared by the surface treatment by sulfonation and is dispersible and/or dissolvable in water in the absence of a dispersant and by adjusting the concentration of a free monovalent anion in the ink to a specified value or lower. SOLUTION: The concentration of the free monovalent anion in the ink is adjusted to 1,000 ppm or lower, Halogen, nitrate, low-mol.-wt. carboxylate ions, etc., are listed as the monovalent anoin. Preferable pigments to be surface- modified are carbon black and organic pigments. Preferably, the surface modification is conducted by grafting sulfo groups to the surface of a pigment with a sulfonating agent (e.g. amidosulfuric acid, chlorosulfuric acid, fuming sulfuric acid, or a sulfonated pyridine salt). The concentration of the free monovalent anion in the ink is decreased preferably by purifying a dispersion containing the surface-modified pigment sulfonated and dispersed therein by reverse osmosis, ultrafiltration, electrodialysis, or the like.

Title: Car body suspension
Inventor: TAKAHASHI NORIYUKI
IPC: B60G17/00
Filed: 1979-12-17
Abstract: PURPOSE:To prevent oil from leakage and enable a wide range of car height adjustment with a small change of hydraulic pressure by providing a piston cylinder for the car height adjustment which is suspended on a car body by an elastic body at the upper end of the piston rod in a hydraulic buffer and which adjoins to the car height adjusting oil room. CONSTITUTION:When oil is sent to an oil room 14 and hydraulic pressure increases slightly, a piston 6 for car height adjustment 6 decreases in a cylindrical body 7, an elastic body 11 is deformed, and the oil room 14 is expanded. Therefore, the car height can be increased. On the contrary, when the oil in the oil room 14 is removed and hydraulic pressure decreases slightly, the elastic body 11 is restored, the oil room 14 is reduced, and the car height is decreased. As described above, by fitting the piston 6 for the car height adjustment in the cylindrical body 7, a wide range of car height is enabled with a slight hydraulic change and hydraulic pressure can be reduced. As a result, oil leakage can be prevented.

Title: Device an method for detecting character string
Inventor: TERAI HIROYUKI
IPC: G06K9/80
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To stably detect character string even when there is nonuniformity of gradation in character image when detecting the position of a character string out of image pickup range before reading character. SOLUTION: A original image (b) of character string fetched by an image input circuit 1 is stored in a gradation image memory 2. An edge section enlarged image (d) is detected near the edge section of the character by an edge detection circuit 3 and an edge section enlarging circuit 4, and based on a background image (e) for which the edge section enlarged image (d) is removed from the source image (b), a gradation nonuniform image (f) is prepared in an image embedding circuit 6. Concerning a differential image (g) detected by a differential image detection circuit 7 between the gradation nonuniform image (f) and the source image (b), an average gradation value in the character string direction is calculated by a projection detection circuit 8, and the character position is decided.  Since the nonuniformity in gradation on the image is first independently detected from the original image and the position of the character string is detected by using the image from which that nonuniformity is removed, even when there is nonuniformity in gradation on the original image, the character position can be stably detected.

Title: Fault detection system
Inventor: NAKANO TAKESHI
Filed: 1986-07-10
Abstract: PURPOSE:To surely detect a faulty location of a node disturbing token control earlier by means of the supervisory system by token control and by system control by using two kinds of node supervisory control systems from a center equipment to apply supervision. CONSTITUTION:The center equipment 10 edits the state by a CPU 13 and a memory 14 based on the state collected from each node 20 by two kinds of supervisory systems, displays the result on a display section 17 via a display controller 16 and applies proper processing to the system. When the token control is not normally operated, forces supervisory information from the center equipment 10 is sent to each node 20. A system control section 15 sends system control information from the center equipment 10 to each node 20 and the center equipment 10 supervises a response and a status. Thus, a node 20 disturbing the token control is detected by reading it from the status till which nodes 20 the supervisory information by the token control is received and from which node 20 the information is not received.
