Title: Liquid transporting drum with removable liner
Inventor: DOWAITO ERISU NIKORUSU
IPC: B65D25/16
Filed: 1991-09-25
Abstract: PURPOSE: To obtain a drum usable for liquid transport in bulk without cleaning before the use. CONSTITUTION: A drum is configured having a cavity enclosed by a base part 14, side wall 16 and upper wall 18 having a port. A liner is disposed within the cavity of an outer drum 12 and fixably secured to a first bung removably fixed on the port. The first bung has a central opening enabling access to the interior of the liner for filling and discharging purposes. When filled with a bulk liquid material, the liner conforms in shape to the shape of the enclosed cavity of the drum. Opening 20 of the first bung is sealed by the second bung engaged to the first bung. When the content is discharged and the drum is emptied and the liner collapses. Then, the first bung is removed from the port and the liner is removed in the state of being collapsed. Thus, a removable liner is provided which eliminates the necessity of cleaning the drum prior to reuse.

IPC: G11B21/16
Filed: 1992-09-16
Abstract: PURPOSE:To provide the method and device for caulking the magnetic head excellent in caulking efficiency, caulking strength and printing reliability. CONSTITUTION:A hollow pin 22 provided in a head assembly 10 is inserted into a fixed hole 7 on an arm part 3 to position them, then a steel ball 25 pushed by a caulking punch 65 is passed in this hollow pin and return-moved by a return punch 64.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject new variant enzyme having high activity and useful e.g. for the quality improvement in the treatment of meat and protein by substituting glycine at a specific position of subtilisin YaB produced by alkalophilic Bacillus YaB with other amino acid. SOLUTION: This new variant subtilisin YaB is produced by replacing the glycines at the 124, 151 and/or 159 sites of subtilisin YaB produced by alkalophilic Bacillus YaB with other amino acids. The enzyme has a substrate specificity different from that of wild-type subtilisin, exhibits improved relative elastin/casein hydrolysis activity and is useful e.g. for improving the quality of food such as the softening of meat, the quality of meat for feed and the quality of product in protein treating process. The variant can be produced by cloning ale gene from wild-type Bacillus subtilis YaB, inserting the gene into a vector, subjecting to site-specific mutagenesis to cause the mutation on the amino acid residues at prescribed sites of the gene product and expressing the gene.

Title: Thin film magnetic head and its production
Inventor: YAMAZAKI HIDEKI
IPC: G11B5/31
Filed: 1990-09-19
Abstract: PURPOSE:To remove a foundation film even in the case of a coil having >=5mum height by setting an interval S(mum) between upper sides of the coil to satisfy S 0.2H+0.5 where H is the coil height (mum). CONSTITUTION:S>=0.2H+0.5 is satisfied where S(mum) is the interval between upper sides of a multiturn copper plated coil of a thin film magnetic head and H(mum) is the coil height. Since the plated coil interval is prescribed in such a manner to form the coil, the frequency in arrival of Ar ions at a Cr/Cu plated foundation film is sufficiently secured at the time of removing the plated foundation film by Ar ion milling even in the case of the narrow coil interval, and the omission of milling is prevented. Therefore, a resistance defect due to inter-coil short-circuit or the like is prevend, and the plated foundation film is removed even in the case of a thin film magnetic head which has about 5mum high coil height and narrow coil intervals.
