Title: Production of ferrite carrier
Inventor: SAITO MASANORI
IPC: H01F41/02
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To easily obtain ferrite carrier cores having fine surface raggedness while keeping almost uniform apparent density and having a specific surface area which does not adversely affect coatability by mixing powders obtd. by firing starting materials for ferrite at two kinds of different temporary firing temps. and then carrying out concluding firing. SOLUTION: Starting materials for ferrite such as Fe2 O3 , MgO, ZnO, CuO and MnO2 are mixed, granulated and fired S4, S14 at two kinds of different temporary firing temps. The resultant powders are mixed and successively subjected to wet pulverization S6, granulation S7, concluding firing S8, crushing S9, size conditioning S10, classification S11, sieving S12 and magnetic separation S13 to obtain the objective ferrite carrier cores S14. The temporary firing temps. are within the range of 800-1,400 deg.C and are different from each other by >=100 deg.C. The desired apparent density and coatability are ensured by regulating the temps., e.g. to 800 deg.C for S4 and 1,400 deg.C for S14. The amt. of the powder fired at the higher temporary firing temp. is preferably 5-30mol% of the total amt. of the powders.

Title: Hydraulic pilot valve
Inventor: HORI HIDEJI
IPC: F15B13/042
Filed: 1990-02-27
Abstract: PURPOSE:To reduce a shock at the time of starting a device by providing a middle diameter part either on the side of a tank port or of an entrance port of a small diameter part that communicates and cuts off the entrance port and a tank port on a spool, and by reducing the gap between the middle diameter part and a spool inserting hole. CONSTITUTION:A middle diameter part 20 is formed on the side of a tank port 9 in a small diameter port 4a of a spool 4, in an integrated manner, and a gap S1 for regulating return flow is formed between a spool inserting hole 21 of a valve 1 and the middle diameter part 20. When the spool 4 is in a neutral position, an entrance port 2 and an oil route 8 are cut off with each other, and pressure oil flows out of the gap S1 to the tank port 9. When the spool 4 is pushed down, until it is in a pressure oil supply position, the pressure oil of the entrance port 2 flows out of a gap S2 to the oil route 8, and runs from the oil route 8 to an exit port 3. Since the pressure oil which is narrowed when it flows in the gap S1 runs slowly, a shock can be reduced thereby.

IPC: B42D15/10
Filed: 1993-02-09
Abstract: PURPOSE:To provide the uncopiable document which is high in visibility and has an uncopiable area with high copying preventing performance. CONSTITUTION:The uncopiable area 2 is formed by printing a group of mesh points or lines as a background part, which is colored in a kind of purple, sepia, deep blue, etc., low in reflectivity in a wavelength range of 500-600nm and shaded in dotted pattern, slantingly to a read reference direction at an angle where moire is generated when the area is copied by a digital copying machine with the density closed to the resolution of it. Then image information is printed on a print layer 4. Consequently, when the document is copied, the uncopiable area 2 becomes blackish and the dotted pattern 3 is superposed on the image information to camouflage the information and generate the moire, and then the image information can not be read to keep secrecy sufficiently.

Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To determine the order of retrieval results and to improve the retrieval results of key word retrieval and retrieval using a feature vector by performing both the retrieving processes at the same time and combining the results. SOLUTION: When a retrieval request sentence is inputted from an input means 11, a word extracting means 16 extracts a word from the request sentence by referring to a word dictionary 14. A vector generating means 17 reads the word vector corresponding to the extracted word out of the word dictionary 14 and converts the request sentence into a request vector. A vector retrieving means 18 calculates the distances between the request sentence vector and data vectors corresponding to respective data in a data base 15 to find meaning similarity. A key word retrieving means 19 searches the data base 15 for data including the extracted word. Then an extended retrieving means 20 scores respective data according to the results of the retrieving means 18 and 19.  Then the extended retrieving means 20 adds the scores of the both by the data and outputs them to an output means 12 sequentially from the data having the largest total scores.
