Abstract: PURPOSE:To decrease the quantity of information of a threshold level of a required matrix and to use a memory with a small capacity by switching an output of a threshold level storage means so that an output picture of the matrix is binarized alternately by 1st and 2nd dither matrixes. CONSTITUTION:A threshold level storage means is provided, which stores a signal of the 1st dither matrix having the distribution of a threshold level with a tendency going to a black level from the middle part and its vicinity and a signal of the 2nd dither matrix having a distribution of a threshold level hardly going to a black level than the threshold level of the 1st dither matrix with a tendency going to a black level from the surrounding part. Then an address generating means 2 reading the threshold level of the two dither matrixes stored in the threshold level storage means 1, a switching means 3 for the output of the threshold level storage means in which the output pictures of the matrixes adjacent vertically and horizontally are binarized alternately by the 1st and 2nd matrixes, and a comparator 4 comparing the multi-value picture data and the threshold level and binarizing the result, are provided on the device. Thus, the quantity of information of the required threshold level of the dither matrix is halved in comparison with the quantity having been required in a conventional device and the capacity of the memory is reduced.

Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To add a new block to conventional blacks in a disk storage space by preparing a new file in the conventional storage space of conventional blacks and applying an attribute. SOLUTION: A conventional file is prepared for logical operation (step 20) and a storage place for the conventional file is allocated (step 21). This file is initialized into the filing space requested for the new block (step 22). Afterwards, this file is marked with an unworked file (step 24). The nuworked file is initialized so as to have the attribute of block. Further, the storage area allocation of unworked file is mapped (step 26). This unworked file allocation map is compressed (step 28) and recorded the compressed map is recorded in a system memory (step 30). At such a time, any peculiar identification is applied to the unworked file allocation map so as to separate it from the original file identification of initialized file.

Title: Column backing steel with stopper
Inventor: NAKAMURA TADASHI
IPC: B23K9/00
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To manufacture the backing steel for manufacturing a column and the like with a simple process by cutting a flat board to a given size and bending it according to the shape of the column. The flat board is manufactured by being rolled to make a protruded part at the center. SOLUTION: The flat board 2 with the protruded part 1 manufactured by the rolling is bent at the bending part 3 to obtain the backing steel 4 for a column. What kind of shape the board is bent to, is various, but it is finally to be engaged with an approximate square of the column end part. It is temporarily tucked at the column end part to be welded. Thus, the various shaped column backing metal with the stopper is formed by only bending the flat board 2. The backing metal is set at the precise position of the column by the stopper so that a welding can be performed without caring the positioning. In other words the protruded length of the backing metal from the end face of the column is always held constant by only pushing the end face to the column, and not only the high accuracy of the size is obtained but also the workability is improved.

Filed: 1994-08-31
Abstract: PURPOSE: To provide a method for dyeing or printing a hydrophobic fiber material or its mixture with a natural fiber material in navy blue with an excellent fastness and very high build-up and dyeing properties by using a mixture of two specific insol. disperse dyes.

Title: Sliding member having superior damping capacity
Inventor: HATTORI TOSHIHIKO
IPC: C23C22/18
Filed: 1986-09-27
Abstract: PURPOSE:To control vibration and noise during sliding by forming a phosphate film on the sliding surface of the body of a sliding member and a heat and wear resistant resin layer on the phosphate film so as to prevent the easy stripping of the resin layer. CONSTITUTION:The surfaces of the teeth of the body T (T1, T2, T3) of a gear are subjected to 'Lubrite(R)' treatment with a phosphate soln. contg. manganese phosphate as an essential component to form a phosphate film 4. Finely powdered fluororesin is stuck to the film 4 and melt-bonded by baking the body T to form a heat and wear resistant fluororesin layer 6. The easy stripping of the resin layer 6 is prevented because the adhesion to the body T is improved and vibration during sliding and noise generated by the vibration are effectively controlled.

IPC: E02F3/92
Filed: 1982-12-27
Abstract: PURPOSE:To raise the efficiency of dredging work by providing a fixed wheel fixed to the fixing shaft at the tip of a ladder, having a sludge discharge hole, side plates to insert the fixed wheel, plural blades fixed between the side plates at a fixed pitch, and a rotary drive means. CONSTITUTION:The ladder 2 of a dredger (not illustrated), a fixing shaft 17, and a fixed wheel 16 are mutually fixed, and an oil-pressure motor shaft 18, side plates 12, and blades 13 are fixed rotatably by an oil-pressure motor 14. When the side plates 12 are turned in the direction of arrow, soil and sand are excavated by the lower blade 13 in contact with the soil of the seabed and continuously scooped up to the space formed by the side plates 12 and the wheel 16. Since the left-handed lower part of the wheel 16 is connected to the sludge discharge port 15, soil and sand are mixed with the sea water and discharged through a sludge discharge tube 3. Since the bucket wheel has no corners to be adhered with soil and sand and the direction of discharging soil is matched with the flow of the sea water, even cohesive soil can easily be transported with the flow of the sea water.

Abstract: PURPOSE:To set conditions of printing of a photograph printing device automatically and make fixed control possible at all times by providing a color separation filter, a logarithmic conversion circuit and an exposure determining circuit etc., and thereby forming a reference picture image without using a standard negative. CONSTITUTION:A reference image is formed through a dimmer filter 2, a cut filter 5 etc., and actual printing density of a printed photographic paper 8A processed by a processing section 10 is measured in the later stage of processing.

Abstract: PURPOSE:To shorten the calculation time of a pointer by displacing an input address in the direction in which an address increases, while holding it in a position relation in which a relative address increases by '1' each from the head address of each data buffer. CONSTITUTION:At a timing 2, a value of a pointer (p) is added by '1' and an output address of a data buffer of each fundamental filter advances by '1' from an address at a timing 1, and a relative address becomes an address of '1'. Also, an input address, as well advances by '1' from the address at the timing 1, and in a data buffer of a fundamental filter of a stage 1, the relative address becomes an address of 2. In the same way, in data buffers of fundamental filters of stages 2-4, relative addresses become addresses of 3, '0' (head address), and '1', respectively. Subsequently, at a timing 5, the value of the pointer (p) becomes 4, and becomes the same as a state that the value of the pointer (p) is '0', and thereafter, the state from the timing 1 to 4 is repeated, and the time required for a pointer calculation is shortened remarkably.
