摘要:
An ID head is formed after a MR head is formed. An upper shield far from a substrate is a first magnetic pole. A nonmagnetic insulator existing through a magnetic gap on the first magnetic pole determines zero throat height, thereby specifying a recording track width of less than 2 .mu.m. The ID head comprises a front end portion of a second magnetic pole, which is exposed to ABS and partly rides over the nonmagnetic insulator, a nonmagnetic insulator for burying a step by the front end portion, a coil which is formed on the nonmagnetic insulator and covered with a nonmagnetic insulator, and a main body portion of the second magnetic pole formed so as to ride over the coil and front end portion. As a result, it is possible to solved various problems of the ID head in which the front end portion of the second magnetic pole is formed first to realize a narrow track width.

A thin film magnetic head includes a recording pole layer that is divided into a tip portion, a wide rear portion, a flare portion, and a yoke portion as viewed from the air bearing surface (ABS). The tip portion and the wide rear portion directly contact a write gap layer. Part of the wide rear portion has a greater width that the tip portion. The wide rear portion is provided between the tip portion and the flare portion to reduce magnetic reluctance. Accordingly, it is possible to improve the pattern accuracy of the tip portion width by providing the flare portion, which reflects a large quantity of light, far from the ABS, while preventing an increase of the magnetic reluctance.

A method for measuring the concentration of creatinine includes the steps of: (A) mixing a sample containing creatinine with a creatinine quantitative reagent including 1-methoxy-5-methylphenazinium in the absence of picric acid and any enzyme responsive to creatinine, to cause the creatinine to reduce the 1-methoxy-5-methylphenazinium; (B) electrochemically or optically measuring the amount of the 1-methoxy-5-methylphenazinium reduced in the step (A); and (C) determining the concentration of the creatinine contained in the sample from the amount of the reduced 1-methoxy-5-methylphenazinium measured in the step (B).
摘要:
A video signal input-output circuit and a recording-reproduction apparatus in which a digitally compressed video signal input in packet form can be recorded and reproduced efficiently and in stable fashion. In this apparatus, a clock reference is detected from a packet signal containing the clock reference and a digitally compressed video signal, a time stamp for a packet is generated using a clock signal in phase with the clock reference and added to the particular packet, and the packet signals with the time stamp added thereto are recorded closely to each other in a data storage element such as a magnetic recording medium. At playback, the packet interval is output by being restored to the original length on the basis of the time stamp added to the packet in store.

In a method for manufacturing a semiconductor device, either a nickel layer or a nickel-based metal layer is formed on a semiconductor substrate by using a plating process. Then, either the nickel layer or the nickel-based metal layer is washed with one of an aqueous hydrochloric acid solution and an aqueous sulfuric acid solution.

A manufacturing method of a semiconductor device which includes wiring dense part and wiring isolated part enables occurrence of ‘Erosion’ to be prevented, as well as it is capable of being prevented occurrence of ‘micro-scratch’ on surface of oxide layer. The manufacturing method sets a plurality of trench-parts on insulation layer, before forming metal plating layer consisting of copper so as to embed trench-parts. Manufacturing process implements annealing in such a way that grain-size of the metal plating layer in the wiring dense part becomes smaller than the grain-size in the wiring isolated part. The annealing, for instance, is implemented with substrate temperature of 70 to 200° C. Subsequently, the manufacturing step perfects the semiconductor device while polishing the metal plating layer to cause the surface of the substrate to be flat.

An object of the present invention is to provide an image-taking device capable of preventing “howling.”When a television set 5 as an external device is connected to an external output terminal of a video camera 1, a controller 17 generates image information to be output via the external output terminal in accordance with the type of external output terminal and outputs the image information to the television set 5; when the operation mode set by a mode setting unit 16 is play-mode, the controller 17 generates sound information to be output via the external output terminal in accordance with the type of external output terminal and outputs the image information to the television 5; and when the operation mode is camera-mode or record-mode, the controller 17 stops the output of sound information performed via external output terminals.

The present invention provides a hybrid video camera that can be downsized while restraining heat generation during operation. The hybrid video camera comprises: a camera block which shoots a subject and generates image data; a hard disk drive which records and reproduces the image data in relation to the hard disk; an optical disc drive which records and reproduces the image data in relation to an optical disc; and a control module which controls operations of these modules. The control module instructs only the hard disk drive to record shot image data from the camera block in the shooting mode, and selects the sleep mode in which the camera block stands ready with the minimum power consumption in the reproduction or editing mode using the optical disc drive.
