Patent JP-H0468280-A (JP)
Title: Refrigerator
Inventor: YOKOGAWA SOICHIRO
IPC: F25D17/06
Filed: 1990-07-06
Abstract: PURPOSE:To diminish noise and avoid uneven distribution of coldness in freezing and refrigerating compartments and a reduction in refrigerating performance by a method wherein a fan is enclosed in a cooler cover and the periphery part of a hole in the cooler cover, which surrounds the fan, has a thickness larger than that of the adjacent part. CONSTITUTION:The cold air is generated by a cooler 4 and discharged by a fan 6 through a hole 19 in a cooler cover 18. The cold air is distributed to an air port 15 and air outlets 13 by a protruding rub 10 on the cooler cover 18 and respectively led to and circulated through refrigerating compartment and a freezing compartment where heat exchange takes place. After that, the wet air is induced by the fan 4 and turned to cold dry air by heat exchanging while it flows through the cooler 4 from bottom to top. The hole 19 is provided in the cooler cover 18 so as to surround the fan 6 and its periphery part has a flange-like shape and a thickness thicker than the adjacent part. Therefore, as the periphery part has a larger mass and is enhanced in rigidity, the periphery part of the hole 19 provided on the cooler cover 18 is prevented from vibrating and producing noise. Moreover, as a clearance is prevented from being created between the protruding rib 10 and a contact face 17 of a grille 12, problems such as uneven distribution of coldness in the freezing and refrigerating compartments and a reduction in the refrigerating performance do not occur.

Filed: 1994-07-08
Abstract: PURPOSE: To reduce noise at the time of reading by securing conversion gain larger than no load gain in a reading period and setting up the conversion gain to approximate zero at the other period. CONSTITUTION: A reading transistor(TR) T2 is provided with positive no load gain G0 . A TR T3 acts as an inverter. The TR T3 is functioned as a current source of which value can be controlled by voltage impressed to its gate. Thereby the dynamic characteristic of output voltage Vs can be controlled to an optimum state. The TR T3 arranged as an inverter has no load gain equal to -G1 . Voltage Vd is voltage at the contact of a diode D and voltage Vk appears on the output of an amplifier 4 of which gain is K. Thereby Vk = K.Vs and Vs = G0 Vd-G1 Vk are formed, so that Vs = G0 Vd/(1+G1 K) is formed. The gain K of the amplifier 4 is changed in accordance with the time interval of its amplification.

Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To provide both a marine moving unit capable of mooring within a prescribed range and further simply moving even into a prescribed sea area and a moving control system therefor. SOLUTION: The position of a moving buoy for a longline is detected (in a step S12). When the buoy for the longline is outside a prescribed sea area (in a step S20), a treatment for driving a propeller 26 is carried out so as to return the buoy to the prescribed sea area (in a step S22). Thereby, the longline connected to the moving buoy for the longline is moored in the original sea area expected to easily catch fishes. For example, the moving buoy for the longline automatically returns to the original sea area even when the moving buoy for the longline is drifted from a desirable position by an ocean current.

Abstract: PROBLEM TO BE SOLVED: To repeatedly use the development and erasure of a color in a good state by erasing the developed color recording formed in a reversible thermal recording medium at temp. equal to or less than the temp. of the center value within a color erasing temp. range. SOLUTION: In a reversible thermal recording medium having a recording layer containing an electron donating color forming compd. and an electron acceptive compd. and forming a developed color state by heating and melting and forming a recording erased state when heated to temp. lower than color forming recording temp., when developed color recording is erased, the crystal growth of a coupler can be suppressed when recording is erased at temp. lower than the temp. within a color erasing temp. range and, therefore, recording is erased at temp. lower than the temp. of the center value of the color erasing temp. range.  The developed color density after repeated use of the recording erasure of the image in the reversal thermal recording medium is lowered and the recording layer of the reversible thermal recording medium is held to heat melting temp. or higher to be developed in color over the entire surface thereof and subsequently erased to restore and reproduce developed color density.
