Title: Starting and stopping device of siphon pipe for backwashing in gravity type filtering equipment
Inventor: MIYAMAE YASUHIKO
IPC: B01D24/46
Filed: 1981-03-31
Abstract: PURPOSE: To easily start and stop the operation of a siphon pipe, by connecting said siphon pipe for backwashing to a water tank and actuating the siphon by the water head difference obtained by discharging water from the tank, and further, sucking the water into the tank by the negative pressure of the siphon.  
     CONSTITUTION: Raw water is fed into a water tank 19 to the water levek A from a manual valve V 6  by closing a manual valve V 5  and opening automatic valves V 2  and V 3 . Next, automatic valves V 4  and V 5  are closed and, automatic valves V 1  and V 2  and the valve V 3  are opened. Consequently, an air pressure in the upper part of an outer pipe 29 is lowered by the flow-out of compressed air in the pipe 29 from a pipe 28, and the water in a tank 19 is discharged rapidly from a sucking and discharging path 23 through a flow-through port 30, and then the air in a siphon 5 is sucked into the tank 19 that causes an actuating of the siphon 5. The valve V 5  is closed when water discharging in the tank 19 begins, and then the air in the tank 19 is sucked by the negative pressure in the upper part of the siphon 5 and waste water after backwashing is sucked up into the tank 19 through the pipe 23 by keeping the valves V 1  and V 2  open, and thereafter, the valve V 2  is closed automatically when the sucked water in the tank 19 reaches the water level A. Further, the stop of the siphon 5 is performed by the valve V 3 .

Filed: 1991-03-12
Abstract: PURPOSE:To offer an image forming device which starts an image forming action at fixed timing regardless of the emitted light quantity of a fluorescent lamp being a light source and which can quickly form an excellent image even at a first copying time. CONSTITUTION:By a control part 22, the fluorescent lamp 13 is made to emit light based on the detection signal of a transfer paper detection switch 23 through an emitted light quantity control circuit 24 and a developing bias control circuit 25 and the bias of a reference level V1 is impressed on a developing roller 43 at the same time. Besides, when the emitted light quantity of the lamp 13 just before the start of the image forming action detected by a light quantity detection sensor 6 does not arrive at a prescribed first reference level C1, it is changed to a second reference level C2 by the control part 22. Simultaneously, the bias value of the roller 43 is changed to the prescribed bias level V2 changed as much as the quantity corresponding to difference between the first reference level C1 and the detected emitted light quantity with respect to the reference level V1.

IPC: B23K35/365
Filed: 1985-03-09
Abstract: PURPOSE:To eliminate the defective formation of a protective cylinder by rod burn and to execute satisfactory arc welding by forming a specific thickness layer of metallic carbonate ore bound by colloidal silica to the outside of the coating layer on a stainless steel coated electrode so that high-temp. drying is made possible. CONSTITUTION:The coating layer 3 consisting of the metallic carbonate ore bound by the colloidal silica is formed to 200-1,000mum thickness on the outside of the coating layer 2 cladding a stainless steel core wire 1. The coating layer 3 protects the layer 2. Drying at about 400 deg.C higher than conventional practice is executed without cracking and exfoliation, by which the moisture content is decreased. The generation of gaseous hydrogen and the drop-out of a flux are prevented in the stage of welding. The collapsion of the flux by the rod burn during heating up of the arbor in the stage of conducting electricity to the rod is prevented, by which the formation of the protective cylinder 4 is improved and the satisfactory welding is executed in a satisfactory gaseous atmosphere. The reason for limiting the thickness of the layer 3 lies in the purpose of forming the protective cylinder to the satisfactory length to eliminate trouble according to welding current conditions.

Title: Oscillating circuit
Inventor: ARAI TAMOTSU
IPC: H03B5/32
Filed: 1982-03-26
Abstract: PURPOSE:To supply an oscillation output signal from an oscillating circuit to an objective system, when the unstable time just after the start of oscillation is elapsed, by using a delay circuit including a capacitor which is charged up with an output signal of the oscillating circuit, stores electric charges gradually and is discharged when the charges reach a prescribed amount.

The output signal of the circuit 6 is inputted to a set terminal of an R.S flip- flop 8. An output Q of the R.S flip-flop 8 is applied to one input terminal of an AND gate 9. An output signal of an inverter 3, i.e. the oscillating output signal of the oscillation circuit main body is applied to the other input terminal of the AND gate 9. When the output Q of the R.S flip-flop 8 goes to a high level, the AND gate 9 is opened and the oscillation output signal of about 4MHz is applied as a clock signal.

Title: Pulse burner
Inventor: SAITO KAZUO
IPC: F23C15/00
Filed: 1989-02-28
Abstract: PURPOSE:To realize the low noise level in the device and at the same time attempt an increase in the heat transfer area with an attempt of miniaturization of the device as a whole by providing in a tail pipe an inner cylinder in which its upstream side in closed and its downstream side is open and its length in the axial direction is set to the wave length of the pulse oscillation and a specific signal. CONSTITUTION:With this pulse burner the combustion gas that flows through the inside of a tail pipe 7a makes reciprocating flow at a high speed in the annular gap that is formed between the inner circumferential face of the tail pipe 7a and the outer circumferential face of an inner cylinder 11. In an exhaust gas decoupler 8 a large noise is liable to be generated because the high speed pulsating flow in the tail pipe 7a is converted into pressure variation. But since an inner cylinder 11 of the length of about 1/4 of the pulse oscillation wave length which has an open end on the side of the exhaust gas is inserted, a pressure variation wave with the phase opposite to the pulse wave phase develops in the exhaust gas decoupler 8 and this pressure variation cancels out the original pressure variation. The amplitude of the pressure variation wave transmitted to the outside from the exhaust gas decoupler 8, namely the noise is thereby much reduced. With this arrangement the volume of a silencer 9a that is provided in the downstream of the exhaust gas decoupler 8 can be of a small volume and it is possible to miniaturize the entire device.

Abstract: PROBLEM TO BE SOLVED: To obtain necessary large driving force by preventing the congestion control to decrease the engine output of a vehicle from being performed when the vehicle performs the course changes such as a right turn or a left turn, etc., and when the vehicle accelerates after passing an intersection point and a toll gate, when the vehicle runs in a low speed state. SOLUTION: When a vehicle judges that the course changes such as a right turn and a left turn are performed for the future based on the road information on the running expected course of the vehicle which is obtained from a navigation system when the vehicle runs in its low speed state, the vehicle judges that the state is not a congestion state and performs the vehicle control of a normal mode without performing the congestion control. When the vehicle judges the course changes are performed for the future, the vehicle judges that the state is the congestion state and performs the congestion control of the vehicle.
