Abstract: In an electronic control unit, a case has a peripheral side portion formed with a concave groove in which a connector is fitted with a clearance portion between the concave groove and the connector. The connector has first inclined portions connecting its lateral surface (one of its base surfaces) and its longitudinal surface (the other of its base surfaces). Each first inclined portion is inclined with respect to the lateral surface at a first angle. The concave groove comprises a base surface opposite to a lateral surface of the connector and second inclined portions opposite to first inclined portions of the connector, respectively. Each second inclined portion is inclined with respect to the base surface at a second angle. The second angle is larger than the first angle. A seal member is disposed in the clearance portion between the connector and the concave groove of the case so that the seal member seals the clearance portion therebetween.

Abstract: Upon executing private print processing, an image forming apparatus acquires a list of spoolers from an IC card which registers information of spoolers which save a print job of a private print mode, and simultaneously requests the acquired spoolers to send a list of print jobs of the user of interest. The image forming apparatus presents, to the user, the list of print jobs acquired from the spoolers in response to the request. When a user selects a desired print job from the presented print jobs, the image forming apparatus downloads the selected print job and executes print processing.

Abstract: An image forming apparatus stores user signature data signed by using a user's second private key, signature object data, public-key certificate data and log data, and creates and stores log signature data by giving a signature to the total of these data by using a first private key. The apparatus calculates hash values for all stored log signature data, adds up the hash values and signs the total hash value by using the first private key, and stores the signed data.

Abstract: An image forming apparatus judges whether the number of pages to print exceeds the number as a reference to judge whether to print many pages based on the setting of a confidential document print job, when receiving the print job. When the number of pages to print exceeds the reference number, the image forming apparatus ejects printed paper sheets to a housing box having a key unit to lock not to be taken out from the main body together with printed confidential documents. When the number of pages to print does not exceed the reference number, the apparatus performs a private print which starts printing and ejecting printed paper sheets to the paper eject unit after receiving an instruction from a user.

Abstract: An image forming apparatus judges whether an identical part is included in the key and the printing contents, based on the result of comparing a previously stored key with the printing contents of a received print job. When the apparatus judges that an identical part is included, the apparatus stores the received print job in a private print job queue for private printing. When the apparatus judges that an identical part is not included, the apparatus stores the received print job in an ordinary print job queue for ordinary printing.

Abstract: A method and apparatus of printing a document in a secure manner, includes receiving, by a printer, print data that has been encrypted using a printer public key. The printer-public-key-encrypted print data is decrypted by the printer using a printer secret key, to obtain decrypted print data as well as user identification information provided with the print data. Print pre-processing is performed by the printer on the decrypted print data, to thereby obtain pre-processed print data. The pre-processed print data is encrypted by the printer using a user secret key to obtain user-public-key-encrypted print data, and the user-public-key-encrypted print data is stored. The user-public-key-encrypted print data is decrypted and printed by the printer upon receipt of a user secret key, prior to printing the print data.

Abstract: There are provided a method and an apparatus in which data created by scanning bits of information such as characters and figures depicted on the depiction board of an electronic blackboard are stored and managed as image data (documents). According to the apparatus and method, when the image data is preserved into a memory device, power-providing processing to permit only a specified user(s) to access the image data is carried out, the specified user(s) being qualified in advance by a power to perform the access. Thus, a limitation is given to access to minute data (i.e., image data) created by holding a meeting with the use of an electronic blackboard or others, whereby security for the data is enhanced.

Abstract: An image forming apparatus includes a camera which photographs an operator, an authentication unit to authenticate whether or not facial data indicating an operator's face photographed by the camera indicates a registered person based on a result of searching for the facial data registered in a facial data storage unit in which the facial data indicating the operator's face is registered beforehand, and a control unit to control an only predetermined function executable by a person other than the registered person in a case where that it is judged that the operator is not the registered person by an authentication result of the authentication unit.

Abstract: The electronic apparatus includes a circuit board on which electronic component is mounted and a chassis housing the circuit board. The chassis is provided with a biasing force applying member applying a biasing force to at least one of top and bottom surfaces of the circuit board to hold the circuit board in position such that the circuit board is allowed to be displaced in a direction parallel to a plane of the circuit board.

Abstract: The present invention provides a novel IP3 receptor-binding protein that is used as an indicator effective for detecting and quantifying IP3, and a method for detecting and/or quantifying IP3 using the same. Determined is an IP3 receptor-binding protein, particularly a novel IP3 receptor-binding protein, IRBIT, which interacts with an IP3 receptor, and whose interaction is regulated by IP3. IRBIT has the characteristic that it can be dissociated from the IP3 receptor by IP3 at a physiological concentration. Because of this characteristic, IRBIT can be useful as an indicator for detecting IP3 by the FRET method or the like.
