IPC: B26D7/08
Filed: 1989-03-28
Abstract: PURPOSE:To prevent a powder dropping phenomenon by directly bringing a magnetic tape contact with a cooling body to cool it to a prescribed temperature and, thereafter, cutting the tape. CONSTITUTION:A pair of rolls 6 are provided in positions just before a magnetic tape 1 goes into cutter blades 4 and 5, the rolls are made hallow, a fluid 7 for cooling such as a nitrogen gas gasified from a liquid nitrogen or a carbon dioxide gas gasified from a dry ice, etc., is made to pass inside, respectively, and by adjusting the flow rates, the surface temperatures of the rolls for cooling are adjusted, and the tape is cooled down to the prescribed temperature. Consequently, the elastic rate of the tape is increased, and the tape shows a hard and fragil character. For such a reason, the stretch at the time of cutting the tape is eliminated, and the cutting can be executed so that the edge is made ideally right-angled to the tape surface. Thus, the power drop to a friction sheet can be reduced.

Title: Method for calcining ceramics honeycomb structural body
Inventor: YASUDA KEIJI
IPC: B01D53/86
Filed: 1989-03-29
Abstract: PURPOSE:To obtain a sintered article of a required size by specifying calcination conditions at the time of calcining the honeycomb structural body obtd. by extrusion molding of the compd. of ceramics raw materials forming cordierite. CONSTITUTION:The chemical compsn. of the essential components consists, by weight, of 42 to 56% SiO2, 30 to 45% Al2O3, and 12 to 16% MgO. Talc, kaolin, and other cordierite forming raw materials are so mixed that the essential components of the crystal phase consist of the cordierite. These materials are mixed and kneaded and a molding assistant and/or molding agent is added to the mixture prepd. in such a manner. The mixture is then plasticized extrudably and is extrusion-molded to the honeycomb structural body. The resulting honeycomb structural body is calcined by controlling the heating up temp. at the time of calcination to <=60 deg.C/hr in the temp. region where the body shrinks thermally or by stopping the heating up for a prescribed period of time or by combining both. The phenomenon in which the shrinkage ratio is varied by a difference in temp. in the respective parts of the honeycomb structural body is relieved or decreased by this method.

Title: Automatic zero-point adjusting method
Inventor: HAJI SETSUO
IPC: G01G23/37
Filed: 1983-04-27
Abstract: PURPOSE:To automatically effect zero-point adjustment, by outputting an initial zero- point correction value in the form of a digital value in a non-load state, converting the digital value into an analog value, and changing the digital value in accordance with the difference between a set value and a difference between the analog value and a tare weight value from a weighing machine. CONSTITUTION:A processor 107a outputs a zero-point correction value Wzi in response to the control effected according to a zero-point adjustment processing program stored in an ROM107b and stores the zero-point correction value Wzi in a memory area MEMi in an RAM107c corresponding to a weighing machine 101-i. The initial zero-point correction value Wc is converted into an analog value as at 108, voltage-divided as at 109 and applied to one of the input terminals of a subtractor 104. Since a weight value Wi measured when the weighing machine 101-i is in a non-load state is being inputted to the other input terminal of the subtractor 104, it carries out subtraction of Wi-Wc  Ws and outputs the difference Ws. A comparator 106 makes a comparison as to magnitude between the difference Ws and a set value Wr. In accordance with the obtained difference therebetween, the digital value is changed such that the difference Ws is equal or substantially equal to the set value Wr. Thus, zero-point adjustment can be automatically effected.

Title: Receiving buffer device
Inventor: NAKAI SHOICHIRO
IPC: H04L13/08
Filed: 1985-04-09
Abstract: PURPOSE:To efficiently utilize a receiving buffer area, by securing the vacant area of a receiving buffer by immediately abandoning a packet causing a buffer overflow as invalid data. CONSTITUTION:A write controlling section 10 successively stores packets inputted in an input terminal 1 in the vacant area of a data memory 5 and causes a latch 16 to hold the leading address of the vacant area of the data memory 5 indicated by an address counter 11 at every time when the reception of each packet is completed by means of its output 10-2. While an address counter 21 which designates the read of the received data of the data memory 5 indicates the leading address of the 1st received packet, an overflow detecting section 15 detects an overflow when the address counter 11 advances beyond the end address of the data memory 5 and coincides with the address counter 21 and the write controlling section 10 stops the reception of this packet and causes the address counter 11 to stored the holding value of the latch 16, and then, resets the value before starting the packet reception.

Title: Manufacture of positive electrode active material for alkaline storage battery
Inventor: TANAKA TAKAAKI
IPC: H01M4/52
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a battery high in positive electrode availability and good in cycle characteristic, by mixing cobalt salt to nickel hydroxide by a same mixing stirrer, transferring it to cobalt hydroxide with alkaline aqueous solution, heating it and simultaneously adding the alkaline aqueous solution to it, and coating the surface of the nickel hydroxide with higher-order cobalt oxide. SOLUTION: When inorganic salt such as cobalt sulfate or cobalt nitrate, and organic salt such as cobalt acetate or cobalt oxalate are sprayed, extremely thin layer on a nickel hydroxide surface is dissolved, simultaneously added alkaline aqueous solution forms a cobalt hydroxide layer, and therefore, uniform and strong coating is formed. Because surface-modification nickel hydroxide is produced by one device capable of stirring and mixing, a process management can be reduced. Because the nickel hydroxide coated with the cobalt hydroxide is stirred in an oxidation atmosphere leaning by-product and is heated with alkaline, higher-order cobalt oxide having a more turbulent crystal structure is produced, and molecular orientation is more multi-directional to improve availability.
