Abstract: A reflow device configured to perform reflow soldering on a substrate having a first component and a second component having a heat capacity larger than a heat capacity of the first component. The reflow device includes a plurality of heating sections applying gas to the substrate, a booth accommodating the heating sections, and a controller configured to perform, at least twice or more times, a heating control of controlling the heating sections to increase both of a temperature of the first component and a temperature of the second component, and then reduce the temperature of the first component while increasing the temperature of the second component.

Abstract: An information reception device is provided with: operation surface which is adjusted to produce a characteristic index vibration by an object contact; a storage device stores candidate information (candidate information is related with the index vibration) which serves as a candidate of input information; a microphone which acquires observation information according to observation of the actual vibration arising in the surrounding environment; and a CPU. The CPU (selecting part) judges whether or not the index vibration exists in the observation information acquired. When the CPU judges that the index vibration exists, the CPU selects the candidate information which is related with the index vibration as the input information.

Abstract: A soldering flux contains a base resin and an activating agent. The soldering flux contains, as the activating agent, an oxygen-containing heterocyclic compound having at least one carboxyl group in a molecule. A solder paste composition contains the abovementioned soldering flux and the solder alloy powder. These enable exhibition of excellent wettability to lead-free metals and plating, irrespective of the type of the metals.

Abstract: A soldering flux contains a base resin and an activating agent. The base resin contains a thermoplastic acrylic resin having a glass transition temperature of below ?50° C. This enables to sufficiently suppress the occurrence of cracks in the flux residue after soldering, under the severe environment where the temperature difference is extremely large. The soldering flux has high reliability and excellent solderability, and is conventional with respect to the load against manufacturing cost and environment.

Abstract: An input apparatus is capable of recognizing an order of selection of a plurality of options displayed in a display region. The input apparatus includes a display unit having the display region with a predetermined coordinate system set thereto, an operating unit including a select key assigned to a direction parallel to one reference axis set in the display region, and a display control unit. The display control unit first causes a predetermined number of options to be displayed in the display region in such an arrangement that predetermined reference points within the options do not have overlapping coordinates in the direction parallel to the reference axis, and that the options form a plurality of rows and a plurality of columns. Then, the display control unit selects one of the options. When the select key of the operating unit is operated by a user, the one option is changed according to the order of selection in response to the key operation.

Abstract: A pen shaped position pointing device used in a position detecting apparatus. A pen-tip segment has side pressure detectors to detect pressure from side directions. The side pressure detectors detect the pen pressure even when the pen is tilted with a large angle. If multiple side pressure detectors are provided, each detector can have a different function, for example, color.

Abstract: A position pointing mechanism for use with a position detecting apparatus, including a pen shaped position pointing device manipulable with one hand of a person operating the mechanism, a rotatable dial having an exposed periphery moveable along the axis of the position pointing device and located on the pen shaped position pointing device so as to be operable with a finger of the one hand in which the position pointing device is held. Provision is made for detecting rotation of the dial, and for detecting relative pressure between the position pointing device and the position detecting apparatus.

Abstract: A primary object is to provide a scanning method resulting in high speed and correct operation in a coordinate data detecting process. The scanning method for succeedingly selecting sensor coils arranged on a sensor plate in a coordinate data input device comprises an interval scanning operation in which a limited number of the whole sensor coils are selected at a predetermined interval space to detect coordinate data of a pointing device. In one preferable mode, the above described interval scanning operation is repeated until a signal representing the existence of the pointing device is detected, and this interval scanning operation is performed on the respective sensor coil arrays. Each interval space includes one to three sensor coils.

Abstract: A rearwardly bent camera has a holding portion adapted to be grasped by the right hand of a photographer. Preferably, the bending angle of the holding portion relative to the front surface of the camera body is in the range of 5 to 35 degrees.

Abstract: A single-lens reflex camera includes a protruding housing portion enclosing a pentagonal prism and an eyepiece optical system. The housing portion has at least two lateral faces connecting a front face and a rear face. The camera includes a flash unit having two arm members fixed thereto. The two arm members can rotate about axis passing through the protruding portion between the lateral faces. The two arm members can assume a first position where the flash unit is disabled and a second position where the flash unit is enabled.
