Abstract: PROBLEM TO BE SOLVED: To reduce starting torque and feed a viscous fluid rapidly to a heating chamber after starting by making the level of the viscous fluid in a storage chamber changeable regardless of the opened/closed state of a recovery passage and a feed passage. SOLUTION: A diaphragm 30 is provided to partition a storage chamber SR into a storage area on the side of a feed hole 2c and a recovery hole 2d, and a non-storage area on the side of an atmosphere hole 2e, and the diaphragm 30 is fixed to a laterally slidable spool 31. At the time of an engine stop, an electromagnetic coil 34 is excited. Then, the spool 31 enlarges the volume of the storage area against the energizing force of a press spring 32, and silicone oil SO in the storage area is fed only in small quantity to a heating chamber 6 with own small weight based on the low level (h) so as to reduce starting torque. After starting, the electromagnetic coil 34 is demagnetized.  The volume of the storage area is therefore reduced, and the level of the silicone oil SO rises and is fed in large quantity to the heating chamber 6 on the basis of the high level so as to attain rapid heating.

Title: Developer stirring method
Inventor: FUJI KAZUO
IPC: G03G15/08
Filed: 1990-09-14
Abstract: PURPOSE:To prevent toner concentration in developer from being erroneously detected by a magnetic permeability sensor by alternately providing a section where a feeding speed is high and a section where the feeding speed is low in the shaft direction of a spiral and stirring the developer in the section where the feeding speed is high in such a state that the developer exists only to the height of the shaft of the spiral. CONSTITUTION:The pitch of the 1st spiral 10a at a part positioned below a toner supply port 60 is made rougher than that at a part positioned above a toner concentration sensor 30. Therefore, the feeding speed of the developer 80 is higher at the part where the pitch is rough than at a part positioned above the sensor 30. At the part where the pitch is rough, the developer 80 is made to exist only to the height of the shaft 90 of the 1st spiral 10a. Meanwhile, the existing quantity of the developer becomes much at the part where the speed of feeding the developer in the shaft direction of the spiral is low. Then, by setting the magnetic permeability sensor at the part where the feeding speed is low, the developer is surely brought into contact with the sensor and the erroneous detection is prevented.

Title: Controller of jet soldering device
Inventor: NOMA KAZUHIRO
IPC: B23K3/06
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a jet soldering device to precisely adjust a wave height of a solder. SOLUTION: After a motor is drived by a prescribed value (S24) and a wave height of a solder is measured (S18), based on the measured solder wave height, the coefficient between a motor drive quantity and a solder wave height is calculated (S22). Further, from the difference between a measured solder wave height and a solder wave height set value, a solder wave height is controlled to a set value based on the calculated coefficient by controlling the motor (S24). Generally in a jet soldering device, by oxidation of solder, etc., the relation between a motor drive quantity and a solder wave height is always changed, because the coefficient between a motor drive quantity and a solder wave height is calculated and a solder wave height set value is set to a set value based on the calculated coefficient, a solder wave height is precisely and quickly adjusted.
