A signal generator for generating test mode signals when any voltage higher than a recommended input high voltage is applied to a predetermined input pin, and for switching from a normal mode to a test mode in response to the test mode signals. A high impedance circuit is coupled between the input pin and a first node. The high impedance circuit comprises a plurality of transistors, the plurality of transistors respectively being connected in series and respectively having a gate coupled with a source or a drain. A signal amplifier is coupled with the high impedance circuit through the first node. A resistor is coupled between the first node and a reference voltage. A transistor is coupled between the first node and a second node between predetermined transistors among the plurality of transistors. The transistor bypasses a current path from the second node to the first node and maintains a potential level of the first node, in response to an output condition of the signal amplifier.

There is provided means for identifying whether or not users of mobile information terminals (mobile information terminals) in a network service are the same as or different from one another. Location information 151, 152 is obtained by the mobile information terminals 121 each comprising a GPS function, and location information 151 representing a resident state at a home, a workplace or a school is obtained when the mobile information terminal users 123 carry their respective mobile information terminals 121. The location information 151 is specific to each user, and therefore, is used as identification information to differentiate the users to thereby allow identification of the users of the mobile information terminals by a management server 110.

A digital multi function peripheral includes a scanner for reading an image in a document read position; a document retaining cover for being able to change an opening and closing state between a state in which the scanner is closed and a state in which the scanner is opened, and conveying a document to the scanner when the scanner is closed; a registration sensor for detecting a leading end portion and a rear end portion of the document conveyed by the document retaining cover; and a controller for determining the opening and closing state of the document retaining cover based on a state of the leading end portion and the rear end portion of the document in the image read by an IR module at a time when a predetermined time frame elapses since a detection state of the registration sensor changes. Therefore, the opening and closing state of the conveyance unit for conveying the document can accurately be detected.

A method for manufacturing a thermally-assisted magnetic recording head is provided, in which joined are: a light source unit that includes a light source having a surface including a light-emission center on the joining surface side of a unit substrate; and a slider that includes an optical system having a light-receiving end surface reaching a back surface opposite to the opposed-to-medium surface. This method utilizes “semi-active alignment” that uses an alignment light, and comprises steps of: causing a light to enter the light source from a surface opposite to the light-emission center; detecting the light that has passed through the light source and is emitted from the light-emission center to align the light-emission center with the light-receiving end surface of the slider; and bonding the light source unit to the slider. This manufacturing method can achieve the alignment with a sufficiently high alignment accuracy in a short processing time.

[Problems to be Solved] To provide a method that is capable of suppressing absorption of lithium ions into the inner portion of a resin collector that is used in a bipolar lithium ion secondary battery.[Means for Solving the Problem] The collector for a bipolar lithium ion secondary battery of the invention has at least two conductive layers. One of the conductive layers that constitute the collector (a first conductive layer) is configured by adding a conductive filler into a base material that contains an imide group-containing resin. The other of the conductive layers that constitute the collector (a second conductive layer) is configured by adding a conductive filler into a base material that contains a polar resin containing no imide group. The collector for a bipolar lithium ion secondary battery is further characterized in that when a bipolar electrode is formed, the first conductive layer is arranged on the positive electrode side.

A thermally-assisted magnetic recording head is provided, in which the light-source output can be adjusted according to its variation by environmental influences and over time. The head comprises: a light source; a write head element provided in a element-integration surface; an optical system provided in the element-integration surface and configured to guide a light emitted from the light source to the vicinity of one end of the write head element; and a light detector for monitoring the light-source output, provided in the element-integration surface and comprising a light-receiving surface covering an area directly above at least a portion of the optical system. This light detector with such a light-receiving surface can detect a leakage light emitted from the optical system as a monitoring light. Therefore, feedback adjustment of the light-source output can be realized to stabilize the intensity of light for thermal-assist applied to a magnetic recording medium.
