Abstract: An air conditioning and ventilating system including: an air conditioning device including a heat exchanger configured to generate conditioned air by heat exchange with a refrigerant; a ventilation device communicatively connected to the air conditioning device and including a supply air fan and/or an exhaust fan; an airflow volume detection unit configured to detect an airflow volume equivalent value of the ventilation device; and a control unit. On determination that the airflow volume equivalent value acquired from the airflow volume detection unit is equal to or less than a first predetermined value, the control unit sets an operation of the air conditioning device to a stop state.

Abstract: A contact terminal (26ai) comprises: a pair of movable side contact pieces (26M) and (26F) which pinch or release a ball-like electrode portion (DVa) of a semiconductor device (DV); a fixed side terminal (26T) having on one end a contact point (26te) coming into contact with an electrode group (PBE) of a printed wiring board (PB); and a fixing portion (26C) which connects proximal end portions of the pair of elastic movable side contact pieces (26M) and (26F) to the other end of the fixed side terminal (26T). The fixed side terminal (26T) formed into a curved shape is elastic and has the one end thereof joined to the fixing portion (26C). The fixed side terminal (26T) is formed of a plurality of curved portions (26ta, 26tb, 26tc, and 26td) and the contact point (26te) provided continuous with one another.

Abstract: An optical fiber loop has a gain medium having a gain at an oscillation wavelength and optical circulators 13 and 14. Collimate lenses 22 and 24 enlarge light bean taken from the optical circulators 13 and 14. A polygon mirror 25 is provided on the light axis, and is rotated. A diffraction grating 27 is provided at the receiving position of the light reflected by the polygon mirror 25, and is of a Littrow configuration which reflects the light in the same direction as the incident light. A selected wavelength changes according to an incident angle to the diffraction grating 27, resulting in increase of selectivity owing to twice incident, thereby permitting to change an oscillation wavelength with narrow band even when changing the selected wavelength by rotating the polygon mirror 25 at high speed.

Abstract: When the size of a printing paper is smaller than a half of the whole area used for expanding the printing data, a method and apparatus for controlling high speed printing in a printer device, having a bit-map memory, a data transfer circuit for transferring video data on the bit-map memory to a printer, and a copying unit for copying the dot-data within a rectangular region on the bit-map memory, include copying the dot-data expanded in a first area on the bit-map memory into a second area that does not overlap with the first area; and sending the dot-data to the printer, and simultaneously expanding the printing data of the next page in the first area. When the size of a printing paper is smaller than the whole area, the method and apparatus include copying the dot-data expanded in a first area on the bit-map memory into a second area that overlaps with the first area in one part; sending the dot-data to the printer; and expanding the printing data of the next page in the first area partially in parallel.

Abstract: In a nameplate apparatus incorporating a communication unit therein, the communication unit is formed in a thin film shape and transmits a coded code specific to the nameplate apparatus. On a front surface of this thin-film shaped communication unit, a display plate is mounted so as to display information such as a name, whereas on a rear surface of the communication unit, a holding member is provided so as to detachably secure the communication unit to a user's clothing or the like. In a data processing apparatus, after the coded code transmitted from the communication unit is determined to be coincident with a predetermined identification code, the data processing apparatus is brought into an operable condition.
