Title: Image reader
Inventor: NAKAMURA YUTAKA
IPC: G06T1/60
Filed: 1995-05-15
Abstract: PURPOSE: To provide an image reader in which preliminary scanning is conducted at a high speed and occurrence of scanning stop due to data processing wait of a host device is minimized. CONSTITUTION: An MPU 2a interleaves one dot as to 8-dots of output signals Ri, Gi, Bi of a shading correction section 2b-1 scanned by a CCD sensor 1a, that is, conducts 1/8 interleaving, the result is received by a line correction section 2b-2 to convert a resolution in the main scanning direction into 1/8 so as to reduce an area by one line of a memory A into 1/8 thereby extending line data storage areas as a whole. In the subscanning direction, one line is received for each of 8 lines corresponding to an arrangement interval of a spectral sensor to convert the resolution into 1/8 and a delay of an output of a green sensor G with respect to an output of a blue sensor B of a head sensor is set to one line and a delay of an output of a red sensor R is set to 2 lines.  Thus, in order to maintain the cross reference of data of the same line, areas by three lines for the blue sensor B, by two lines for the green sensor G and by one line for the red sensor R are enough. Scanning data are stored by using excess areas.

Abstract: PURPOSE:To prevent oil from diffusing and to facilitate removal of oil by providing an oil reservior at the lower end of a partition plate for partitioning a heating chamber and a cooking chamber, and applying a fluorine resin on the surface of the oil reservoir. CONSTITUTION:When a food (f) having much fats and water contents is heated and cooked, air within the oven case flows ss shown by arrows, that is, air is sucked up from a suction port (d) formed in a partitioning plate 4' and is exhausted through an exhaust port (e). Oil scattered from the food (f) is concentrated in the vicinity of the suction port (d) of the partitioning plate 4' and a large amount of oil adhere to the partitioning plate 4'. With the increase in the adhered oil, it drops onto an oil reservoir 11 and is collected. Further, a fluorine resin is applied to the surfaces of said partitioning plate 4' and the oil reservoir 11 or a steel plate applied with the fluorine resin beforehand is used whereby oil adhering to the partioning plate 4' is easy to drop onto the oil reservoir 11 and hence oil in the partitioning plate 4' and the oil reservoir 11 can be easily cleaned and removed.

Title: Expansion tank for water-cooled cooling device
Inventor: KAWAMOTO TSUKASA
IPC: F25D17/02
Filed: 1989-05-09
Abstract: PURPOSE:To absorb the fluctuation of water level in the casing so as to maintain the atmospheric pressure therein and prevent the intrusion of foreign substances as well as the dissolution of air into the water by installing a flexible membrane in the breather hole of the tank casing to hermetically separate the tank interior space from the atmosphere. CONSTITUTION:Under operating conditions, the pressure in the sealed space in the upper part of the casing 62 delimited by the surface of cooling water 8 and the membrane 63 is maintained at Po which is the atmospheric pressure. If the water level in the tank casing 62 should fluctuates due to the expansion or contraction of the cooling water caused by the water temperature change, the membrane 63 responds to expand or contract to absorb the expansion or contraction of the cooling water without causing a pressure change in the cooling water 8. Further, as the cooling water 8 is separated from the atmosphere by the membrane 63, the intrusion of external foreign substances and the dissolution of air into the cooling water in the casing can be positively prevented.

Title: Heat excharger
Inventor: NINAGAWA NORIO
IPC: F28F1/00
Filed: 1984-06-06
Abstract: PURPOSE:To effectively exchange heat between refrigerant and water by a structure wherein heat transfer medium is jetted from the inside of an internal jet pipe to the inner wall of an outside heat transfer pipe, which consists of double pipe structure together with the jet pipe. CONSTITUTION:Gaseous refrigerant 7 flows from the inlet 13 of a double pipe heat exchanger 4 not shown in the figure into a jet pipe 19, the tip of which is plugged and the inlet of which is expanded so as not to allow the refrigerant to flow directly into an outer pipe, so as to be blasted through jets 20 provided circumferentially and axially on the jet pipe 19 to the inner wall of a heat transfer pipe 16 at the positions for heat transfer medium to pass through easily in order to condense and liquefy, resulting in giving off heat of condensation, which is conducted to the water contacting with outside surface fins 17 in order to heat the water. At the start of heat collecting operation, gas condenses and liquefies in the jet pipe 19 by contacting with the inner wall of the jet pipe 19. However, as the temperature of the jet pipe 19 itself rises, the amount of condensate in the jet pipe 19 becomes less and the liquefaction occurs almost in the wall surface of the outside heat transfer pipe 16. Because high pressure gas jeted from the jets 20 scatters liquid refrigerant adhered onto the inner wall of the heat transfer pipe 16 and consequently contacts directly with the inner wall of the heat transfer pipe 15, resulting in realizing effective heat exchange.

IPC: G03G15/04
Filed: 1990-05-09
Abstract: PURPOSE:To vary the light output of a laser diode (LD) by providing an element which controls the by-pass quantity of a current which flows to the LD. CONSTITUTION:When an image signal VA is inputted to an ON/OFF control terminal 26 and a control transistor (TR1) 25 turns off, a LD 21 is emitted, a light signal which is monitored by a PD 22 is inverted by an inverting amplifier (AMP) 29 applied to the gate G of an FET 28. This FET 28 has characteristics at the N channel as shown by graphs, so when the light output of the LD 21 becomes strong as shown by the graphs F, E, and D, a current which flows to the FET 28 increases, but when the light output of the LD21 become weak, on the other hand, the current which flows to the FET 28 decreases, so that the light output of the LD 21 can be constant at all times irrelevantly to temperature, etc. Then the base current of a driving transistor (TR3) 24 can be adjusted with an input voltage VB. Consequently, the light output of the LD 21 can easily be varied.
