Title: Safety device of burner
Inventor: KAWASE TOMOYUKI
IPC: F23N5/24
Filed: 1983-12-19
Abstract: PURPOSE:To improve the safety by so constituting the titled device that the same does not perform combustion action when a predetermined procedure is not followed, by providing a device deciding whether a user has operated the titled burner according to the predetermined procedure or not. CONSTITUTION:When a switch 11 had been opened at the time when power supply from a power source circuit 2 was started, as it is an instant to generate voltage on both ends of a resistor 12, a base current is not applied to a transistor 16 even if a swtich 11 is turned ON, base voltage of a transistor 23 is kept constant, constant voltage is applied to a combustion control circuit, and a burner is burnt when a solenoid valve is opened and an ignitor is made to open. When the switch 11 had been closed at the time when the power supply was started, voltage is generated on both ends of the resistor 12 in an instant untill charge to a capacitor is completed, the base current is applied to the transistor 16 through the voltage and a SCR18 keeps a conductive state. Then the base current is not applied to a transistor 23 and the transistor 23 is in an OFF state. Then a power is not applied to a combustion control circuit 1, the solenoid valve is kept closed and the burner does not burn.

A head heating resistor 4 is serially connected to a driver 5 to be connected between the 24V power source of the switching regulator 2 and a GND. The 24V power source voltage is applied to a three-terminal regulator 6 to be converted to 5V, thereafter being applied to the Vcc terminal of the conduction control IC 3 through a diode D2. In this manner, the power source of the conduction control circuit is made to rise immediately at the time of power ON and fall slowly at the time of power OFF.

Title: Rectifying column
Inventor: SEKI KAZUO
IPC: F25J3/02
Filed: 1987-09-24
Abstract: PURPOSE: To increase the flow speed of an ascending gas and reduce the diameter of a rectifying tower by providing a demister for capturing the mist of a liquid that ascends along with a gas to the upper portion of a rectifying plate in the rectifying tower such as an air liquefying separator. CONSTITUTION: A reflux liquid L that flows down from an upstream part goes over a weir 4 at the edge and center parts of an upper rectifying plate 2, flows onto a lower rectifying plate 2b from a drop port 5, and successively flows down to lower stages from a central drop port 6. On the other hand, a rising gas G rises from a number of ventilation holes 7 of each rectifying plate 2 and passes, as air bubbles, through the reflux liquid L that stagnates at the height of the weir 4 on the rectifying plate 2. However, the mist of the reflux liquid L that rises along with the air bubble at this time is captured by a demister 8 being provided between the upper and lower rectifying plates 2a and 2b.  The demister 8 is fixed with a wire 9 by laminating a plurality of wire netting with a proper mesh, and allows the captured mist to grow and drop onto the lower rectifying plate 2 as a liquid particle, thus increasing the flow rate of the rising gas and reducing the diameter of a rectifying tower.

Title: Three-dimensional graphic transmission/reception method, recording medium and three-dimensional graphic transmission/reception system
Inventor: KITAZAWA HITOSHI
IPC: G06F13/00
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To attain reduction of a waiting time until a three-dimensional graphics is received by a client where its display and operation becomes possible by preparing data members different in capacity respectively in accordance with their utility conditions regarding a single three-dimensional graphic. SOLUTION: When a client 26 demands three-dimensional graphic data of a server 21, the data are transmitted to the client 26 from the server 21 in the order of demand. In doing so, the data in the server 21 are segmentally held as data members 22 to 24 so that they are adapted to a utility condition of the client 26 and, if one of them reaches, display/operation of the data becomes possible with the client 26. For example, regarding data A, at the point of time when an A1 of the data member reaches, the display/operation is enabled. Since the data member A1 is smaller in comparison with the data A, a time 27 that the client 26 has to wait for until the reception completed is apparently shorter than the time of an existing method.

IPC: B60B33/00
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a carrying truck capable of suppressing even a shock and oscillation given to a load to a minimum when objects are carried and also when it crosses a level difference such as projections and grooves in order to prevent an extra shock from being given to a load on a transportation carriage because the load may be moved largely in longitudinal or lateral direction when the carrying truck on which an impact absorbing mechanism is installed crosses the level difference such as projections or grooves. SOLUTION: A carrying truck comprises a platform 2 loaded with articles, an operating handle 3 operated to press or pull the transportation carriage 1 for movement, and casters 4 used for movement. Also six casters 4 are installed on the carriage, and a suspension mechanism such as coiled spring 5 is installed on the caster 4. The casters 4 opposed to each other in lateral direction are shifted from each other in longitudinal direction of the truck. Thus a balance of the carring truck during crossing a level difference can be kept, and a shock or oscillation can be suppressed from occurring to a minimum.

Title: Washing method by siphon type water closet
Inventor: SHIBATA SHINJI
IPC: E03D11/02
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To save water by discharging an air mass in a trap waterway as it is to the outlet of a drain waterway. SOLUTION: A washing water storage section 4 is provided at the front of a drain trap 2, and a jet discharge opening 6 of a throat 61 is opened at the front wall portion of a recessed portion 1b. When a high pressure washing water is flowed at a high speed from a discharge nozzle 5 to the throat 61, then water in the storage section 4 is pulled in quantities to the inside of the throat 61 through a side surface hole of the throat 61 and is discharged in a form of a jet flow from the discharge hole 6 to a trap inlet 2a, and water inside the storage section 4 flows out from a gap portion between the tip portion of the throat 61 and the storage section 4. Because of this, a large amount of washing water flows into the trap 2 at a time and sewage is forcefully pushed into the trap 2. Moreover, an upper portion of the inner wall above an apex portion 2g is formed to a shape which permits the outflow of the washing water without gap, so that air is discharged as it is in the form of an air mass. By doing this, air is not entrained in the washing water so that energy loss can be considerably reduced and water can be saved significantly.
