  • Patent number: 7751946
    Abstract: In a remote control system, the remote control of a vehicle function is executed. The remote control system includes a control terminal and a cancellation device. The control terminal transmits a request for the remote control of the vehicle function to a vehicle. The cancellation device cancels the remote control of the vehicle function if the local control of the vehicle function is requested before the remote control of the vehicle function is executed according to the request for the remote control.

  • Patent number: 7534547
    Abstract: A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A-[(J)m-(X-Pro)]n??(1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

  • Publication number: 20080135808
    Abstract: The immersion oil has refractive index which is 1.70 or more, and is low autofluorescence. Preferably, the main ingredient is iodine compounds (diiodomethane), and a solid having a high refractive index such as sulfur and the like is dissolved or dispersed into the immersion oil. The production method of the immersion oil has a purification process, in which impurities are removed preferably by adsorbent, distillation or recrystallized. In the method of preservation of the immersion oil, it is always contacted with the adsorbent. The preservation container of the immersion oil contains an adsorbent which is always contacted with the immersion oil.

  • Patent number: 6510136
    Abstract: A signaling virtual channel (SVC) is established only when it is necessary so that a bandwidth reserved for a signaling channel for transmitting signaling information is usable for transmitting communication information. The SVC is established between a subscriber terminal and an asynchronous transfer mode (ATM) exchange system by selecting the virtual path identifier (VPI) and the virtual channel identifier (VCI) for signaling only when a request for a call connection is made by the subscriber terminal or only when a notification of reception of a call is sent to the subscriber terminal. A communication path between the subscriber terminal and the ATM exchange system is established for transmitting communication information by transmitting communication call setting information through the SVC. The SVC is released after an establishing operation of the communication path is completed.
