Title: Shroud tank and injection tube for boiling water type nuclear reactor
Inventor: DAGURASU MAABIN GURANZU
IPC: G21C15/18
Filed: 1989-02-08
Abstract: PURPOSE: To protect the core against damage by disposing a shroud tank above the core and disposing means for injecting a low temperature coolant into the tank and means for discharging the low temperature coolant from the tank upon missing the coolant in the tank. CONSTITUTION: This shroud tank 60 having open top end and closed bottom end surrounds a tubular column 37 and a plurality of drainage holes 62 are made around the bottom. During normal operation, peripheral water level in a reactor 30 is higher than the top part of tank 60 which is thereby fed with low temperature coolant at low flow rate through an injection tube 66. Pressure level is substantially equal on the inside and outside of the tank 60. In case of loss-of-coolant accident, the majority of water on the outside of tank 60 is evaporated and the water level in reactor 30 drops below the open top part of tank 60.  Since the hydrostatic pressure on the inside of tank 60 increases over a corresponding hydrostatic pressure on the outside, cooling water injected into the tank 60 flows at an increased flow rate into the lower region 28 of reactor vessel 38 through a discharge hole 62. Consequently, the core 36 is covered with the coolant.

Title: Combustion device for liquid fuel
Inventor: MIFUNE HIDEO
IPC: F23Q2/44
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To quickly eliminate a difference between internal and external pressures of a fuel tank by providing an air path at a portion except for a fuel path through a wick to make a communication between the inside of the fuel tank and the outside air at least during the combustion period. SOLUTION: When combustion is started with an ignition caused at the tip of a combustion wick 6 by an ignition member 10, a liquid fuel is supplied to a combustion section 61 from a suction part 62 by a fuel path through a combustion wick 6 corresponding to a fuel consumption at the combustion section 61 associated with the combustion. Then, the liquid fuel in a fuel tank 2 is gradually sucked up and the reduced capacity of the liquid fuel within the fuel tank 2 causes an internal pressure to lower, which tends to block the suction of the fuel. But an air path 20 is opened to let air outside flows in through the air path 20 according to a pressure difference. The elimination of the pressure difference allows quick supply of the fuel to the combustion section 21 without being blocked.  This stabilizes the length of a combustion flame being balanced early from the initial start of the combustion.

Title: Line-of-sight detecting device
Inventor: OTSUKA YASUNOBU
IPC: G03B13/36
Filed: 1993-02-17
Abstract: PURPOSE:To provide a line of sight detecting device which is inexpensive and whose constitution is simple. CONSTITUTION:When a photographer looks at a mask 5 through an ocular 4, the hole of the mask 5 becomes an aim. The hole of the mask 5 is irradiated with light having specified wavelength by an LED 1, the optical image of the shape of the hole of the mask 5 is formed on the retina by a lens being the eye of the photographer. Furthermore, reflected light from the retina by the optical image of the shape of the hole is formed into an image by the reflected light again at the hole of the mask by the lens being the eye of the photographer. Then, the light is relayed by a condenser lens 3 again, separated by a half mirror 2 and then conducted to a photodiode 7. The reflected light from the retina reaches the photodiode 7. Since reflection corresponding to the hole of the mask at the position of a fovea centralis becomes much, the direction of the line of sight is detected by comparing output from each photodiode 7.

Title: Network test system
Inventor: MURAYAMA MASAMI
IPC: H04M3/26
Filed: 1981-02-27
Abstract: PURPOSE:To achieve test of networks only with the change in an internal time slot, by using a pseudo terminal device in which the phase difference can be changed. CONSTITUTION:A data on an external slot converted at a demultiplexer DMPX is transmitted to a multiplexer MPX via a shift register SR1 of a pseudo terminal device PTU. In folding transfer through an opened gate G1, the internal time slot number of the DMPX and that converted at the MPX are the same, and in folding transfer with an opened gate G2, they are different. A flip-flop FF latches a data of the internal slot from a selector SEL2 with a folding instruction given via a signal reception distributor SRD from a central control unit CC and folds it via SELs 3 and 1. Thus, the test for network can be made by using the difference between the internal time slots from folding with the PTU and with the FF.

Abstract: PURPOSE:To steadily keep a constant pressure wave, by applying the positive or negative pulse having a specific width with respect to the primary resonance wavelength of a common ink chamber to a pressure generating means at a cycle 1/integer-times of the primary resonance. CONSTITUTION:By a drive system pressurizing at first and attenuating after the elapse of a definite time, a positive pulse having a width 1/4 the primary resonance wavelength of a common ink chamber 4 is continuously applied at a cycle 1/integer-times the primary resonance. In this case, a pressure wave A having the same mode as the primary resonance frequency of the common ink chamber 4 is generated in the common ink chamber 4. As mentioned above, since the applied pulse becomes the mode coinciding with the pressure response of a head itself, pressure amplitude can be made max. By a drive system attenuating at first and pressurizing after the elapse of a definite time, a negative pulse having a width 1/2 the primary resonance wavelength of the common chamber 4 is continuously applied at a cycle 1/integer-times the primary resonance. B is the pressure wave generated in the common ink chamber 4. In this case, pressure amplitude can also be made the max.

Abstract: PURPOSE:To eliminate the need for reply holding switch and to guarantee the safety drive by detecting a ripple frequency at automobile driving, outputting a driving signal and sending a reply holding signal by the driving signal at the arrival of call to the mobile machine. CONSTITUTION:In the setting of detecting value of a ripple frequency by a ripple frequency detection section 1 to a value corresponding to that at driving, the ripple frequency is increased during driving and when it reaches a setting value or above the ripple frequency detection section 1 detects the presence of the ripple frequency over a setting value and outputs a driving signal 1a to the reply holding signal transmission section 2. The reply holding signal transmission section 2 ANDs the driving signal 1a and the incoming signal 4 and sends the reply holding signal 2a when the driving signal 1a and the incoming signal 4 are received. Thus, in case of the arrival of a call during the drive of the automobile, the reply holding signal is sent automatically.

Abstract: PURPOSE:To make the tone scale of a bell tone variable by providing a bell tone signal sending means, a time constant circuit, a variable impedance means, and a sounding body connected between the bell tone signal sending means and the variable impedance means. CONSTITUTION:When a bell signal arrives to telephone circuits L1, L2, a bell tone signal is output,ed from an output terminal of a ringer IC1. Part of the bell tone signal is changed gradually in a capacitor C1 via a resistor R1, the potential at a connecting point between the capacitor C1 and the resistor R1 rises gradually. Thus, the base potential of a transistor(TR) Q1 is increased gradually via a resistor R2 and a diode D1 and the internal resistance is increased. Then the internal resistance of the TR Q2 is gradually smaller in opposition to that of the TR Q1, then most of the bell tone signal from the output terminal of a ringer IC1 is given to the TR Q2 via a matching transformer 8. Thus, the bell tone from a speaker 7 is increased gradually.
