Title: Artificial snow falling device
Inventor: ISODA YUKIO
IPC: F25C3/04
Filed: 1990-11-30
Abstract: PURPOSE:To make a uniform distribution of blown snow concentration in a vertical direction at a nozzle blowing port by a method wherein an opening or closing deflector having a plurality of slit-like aeration ports formed in a direction crossing with such a direction as one in which one end of an auxiliary deflector is moved up or down and for making a variable width of each of the aeration ports is installed at a lower part of a snow scraping shooter. CONSTITUTION:As a gear motor 6 is rotated in a direction indicated by an arrow, each of wires 7 is moved in a direction indicated by an arrow. As a result, each of deflectors is moved in the same direction as that of the wire and a deflector 3 is operated in a direction to close. If the gear motor 6 is rotated in a reverse direction, the deflector 3 is moved to open. The auxiliary deflector 4 is operated such that a gear-rack 5 performs a vertical movement with the gear motor 6 and the deflector 3 performs the vertical movement in a slant direction. In this way, it is possible to set a degree of opening of the opening or closing deflector 3 to any optional position, so that even if an amount of blown snow or an air speed is varied, the most appropriate degree of opening is selected to enable a uniform distribution of concentration of blown snow.

Title: Steam generator
Inventor: KAMIMURA YUTAKA
IPC: F22B37/56
Filed: 1987-12-25
Abstract: PURPOSE:To prevent scale pieces from being deposited in a tank by delaying the stop of a heat source after a drain valve is opened. CONSTITUTION:When stop operation in the operation of a steam generator is performed, a drain valve 12 is opened and the water in a tank 2 is energized by steam pressure P1 to drain. After a delay means 42 of a control device 40 is actuated and the drain valve 12 is opened, gas feed is stopped within 3sec. When the tank 2 is rapidly cooled and contracted, adhering scales 22 are peeled off and fall on the lower part of the tank 2 by the difference in coefficient of thermal expansion. The fallen scale pieces 22' are eliminated outside together with the water 19 in the tank 2. Since pressure P1 in the tank is lowered a little with the opening of the drain valve 12 because of drain, but since extinguishment of the burner 1 is delayed, drain and scale piece elimi nating efficiency are good and scale pieces 22' are not deposited in the tank 2 because of draining effected as the pressure is held.

Title: Sounding body driving device
Inventor: ISHIHARA YUJI
IPC: G10K9/12
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a sounding body from becoming a noise source during nighttime drive by providing the sounding body connected to a logic circuit and a photoconducting element, and varying the resistance value of the photoconducting element according to variation in the quantity of peripheral light and varying the sound pressure of the sounding body. CONSTITUTION:The feeding circuit for the sounding body 2 which is controlled by the logic circuit 1 is provided with the photoconducting element 3 which varies in resistance value according to its circumferential brightness and a potential applied to the sounding body 2 varies with the circumferential brightness, so that the sound pressure varies. Therefore, when the circumference is bright, the resistance value of the photoconducting element 3 is small and almost all of the potential of the output signal of the logic circuit 1 is applied to the sounding body 2, which generates high sound pressure. When the circumference is dark, on the other hand, the resistance value of the photoconducting element 3 increases and the potential applied to the sounding body 2 drops, so that only low sound pressure is generated. Consequently, a clear sound is generated when the circumference is very noise in daytime and a noise is evaded when it is silent in nighttime.

Title: Signal transmission circuit
Inventor: NISHIO YOJI
IPC: G06F12/00
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To make the value of a reference voltage in an input circuit large and to use a fast differential input circuit with a configuration that receives an input signal with an NMOS transistor by making the value of a termination power supply voltage equal to or more than the value of a power supply voltage in an output circuit. SOLUTION: In a stub series terminated logic(SSTL) bus configuration, a power supply voltage VDDQ in an output circuit sets a termination power supply voltage VTT to VTT>=VDDQ in the range from 1.5 to 2.5 V. That is, the voltage VTT is set so as to be the voltage VDDQ value or more. In such a case, for preventing a current that flows through a PMOS transistor that constitutes a data output circuit 11 when a bus is in a high impedance state, attention is needed for the threshold voltage value of the PMOS transistor. Moreover, the PMOS transistor needs to be replaced with an NMOS transistor. Therefore, it is possible to make a reference voltage Vref in an input circuit 12 large.
