Abstract: PURPOSE:To represent the delicate linear design and luster of original drawings by printing a pattern of line drawing tone on a colored or solid color printed paper or resin sheet with a metallic ink, and after that printing a desired pattern again on the once printed paper or the resin sheet. CONSTITUTION:A pattern of line drawing tone is printed on a colored or solid color printed paper, a resin film, or a film. This pattern of line drawing tone shall be of metallic printing and a gravure plate having line drawing patterns composed of stripes, herringbones, waves or combinations thereof, or pattern of wood texture, etc. is used. After that, a pattern of grain of wood, or a pattern of grain of stone, or a pattern of abstract design is printed. For printing this pattern, it is desirable that a transparent ink be used so that the pattern of line drawing tone previously printed with metallic ink can be effectively seen from outside.

Abstract: PROBLEM TO BE SOLVED: To prevent water leak preventive work from being complicated while suppressing cost increase by making a pipe through hole in the top face at a hollow raised part formed integrally on a bottom plate while projecting upward. SOLUTION: A raised part 1 having a hollow section 3 is formed integrally on the bottom plate E1a of a lower water tank Ea and a through hole L11a for passing a water supply pipe K11a is made in the top face 2 thereof. The lower water tank Ea is mounted on a frame F previously fixed with a water supply header K1a and the water supply pipe K11a and secured in place. Upper end of the pipe L11a penetrates the through hole L11a made in the top face 2 and projects while taking account of a coupling margin with a water supply manifold K111a. Since water pressure is not applied substantially, a positive leak preventive measure is not required at the through hole L11a thus enhancing the efficiency of water leak preventive work while reducing the cost.

Abstract: PURPOSE:To speed up character string conversion speed by retrieving a dictionary by individual fields and registering a character string concerned to a standard dictionary when there is no character string concerned in the standard dictionary. CONSTITUTION:A conversion means 2 retrieves the standard dictionary 4 with data inputted by an input means 1. When there is the character string concerned, the character string is transmitted to an output means 3. When there is no character string concerned in the standard dictionary 4, the character string is retrieved from the dictionary by individual fields 6 so as to convert it. Then, the character string converted in a special word registration means 5 is registered in the empty area of the standard dictionary 4. When the same character string is converted, conversion is realized only by retrieving the standard dictionary 4. When there is no character string concerned in the dictionary by individual fields 6, inputted data is outputted as it is.

Title: Power steering system
Inventor: MITANI SHIGEO
IPC: B62D5/04
Filed: 1986-02-06
Abstract: PURPOSE:To prevent a motor from self-propelling in a motor-driven type power steering system, by installing a circuit which performs constant torque control over the motor. CONSTITUTION:When a driver gets steering and rotates a steering shaft, the number of revolution in a motor 5 goes up via a gear, whereby a signal is inputted into a microcomputer 1 from a speed detecting circuit FG4, and when the speed reaches the specified value, a command turning the motor to ON is emitted out of the microcomputer 1. This command turns a control circuit 3 to ON, and rotates the motor 5 while controlling it with constant torque so as not to exceed the extent of steering torque. Thus, such a circuit that performs the constant torque control over the motor 5 is installed whereby the motor 5 is preventable from being self-propelled. Therefore, such a possibility that the motor in a motor-driven type power steering system might be self- propelled is thus preventable so that its practical effect is large enough.

Title: Work vessel for electric discharge machine
Inventor: YOKOMICHI SHIGEJI
IPC: B23H7/02
Filed: 1990-02-05
Abstract: PURPOSE:To minimize displacement of a lower arm to enhance work precision by providing a flexible seal plate for sealing the lower arm on a seal guide side plate arranged on a side surface of a work vessel and rotatable rollers on the seal guide side plate at the outside where hydraulic pressure is applied. CONSTITUTION:When a working fluid is filled in a work vessel 27, a flexible seal plate 45 bends outward due to the hydraulic pressure. When the work vessel 27 moves in the right/left direction under this condition, since one end of a lower arm 21 is fixed, the seal plate 45, being pushed by the lower arm 21, moves relatively to a seal guide side plate 41. Rollers 47 rotatably installed on the seal guide side plate 41 correct the bending of seal plate 45 and push the plate 45 into the seal guide side plate 41 to minimize the frictional resistance between the seal plate 45 and the seal guide side plate 41. Accordingly, the force acting on the lower arm 21 is reduced and the displacement of the lower arm 21 supporting a lower wire guide device 25 for guiding a wire is minimized.

Title: Bus control circuit
Inventor: KITAMURA TETSUYA
IPC: G06F13/42
Filed: 1989-02-02
Abstract: PURPOSE:To transfer data to an input/output circuit without degrading the performance of a microprocessor by using a data latch circuit, plural flip-flops, and gates to form a bus control circuit. CONSTITUTION:The AND gates 21 and 22 are added together with an OR gate 23, flip-flops 24 and 28, and a latch circuit 29. A microprocessor 11 activates a ready signal in the minimum data transfer cycle. The input/output write signal received from the microprocessor 11, the chip selection signal obtained by decoding an address, and data are held by the circuit 29 just for a latch enable period which is decided by the added flip-flops 24 - 28. Then a data writing operation is kept waiting to an input/output device until the processor 11 gives an access to a bus. Thus it is possible to transfer data to an input/output circuit 12 without degrading the performance of the microprocessor 11 as long as the data writing cycle set to the input/output device is larger than the least cycle of the microprocessor 11.

Title: Purification of phosphate-contg. water
Inventor: JIYOUKOU ISAO
IPC: C02F1/28
Filed: 1982-02-19
Abstract: PURPOSE:To remove residual chlorine, by bringing phosphate-contg. water into contact with calcium phosphate-contg. crystal seeds at pH above a specified value in the presence of Ca<2+> and a chlorine agent and then with a Ni or Co catalyst to lower pH and P content of the water to be purified. CONSTITUTION:Phosphate-contg. water is brought into contact with calcium phosphate-contg. crystal seeds such as hydroxyappatite, fluoroappatite or trilime phosphate at pH above 6 in the presence of Ca ion and a chlorine apart. As a result, calcium phosphate formed from phosphates in the water precipitates on the surfaces of the crystal seeds to remove phosphoric ion from the water. In this case, the chlorine agent decomposes organic substance adherent to the surfaces of the crystal seeds and inhibits the formation of slime, so that the surfaces of the crystal seeds are held clean and that the efficiency of removing phosphates by precipitation is improved. In succession, the water is brought into contact with a Ni and Co catalyst to lower pH of the water to be purified and to decompose residual chlorine and organic substance. Accordngly, still remaining calcium phosphate is removed too.
