Title: Soldering method for printed-circuit board and jet solder tank
Inventor: ZEN MITSUO
IPC: H05K3/34
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To obtain a soldering method in which solder in a large amount is stuck to a part, to be soldered, at a printed-circuit board and which prevents metal fatigue from being generated in a soldered part by a method wherein a step is formed in molten solder which flows out to the withdrawl side of a jet nozzle and the printed-circuit board is removed from the part of the step. SOLUTION: A part of molten solder which is jetted from a jet nozzle 2 flows along an entry-side former 6, and a part flows along an exit-side former 7. In the molten solder which flows along the exit-side former 7, a step is formed by an up-and-down plate 12 at a step formation device 11 installed at a jet solder tank 1. The flow velocity of the molten solder is slow at the upper part of the step, and the flow velocity in the part of the step is faster than that in the upper part. Then, the flow velocity in the lower part of the step is slower than that in the step but faster than that in the upper part. The flow velocity in the step is adjusted by changing the angle of the exit-side former 7 (as shown by an arrow V). The adjustment can be performed fine even by using a clam plate 10.

Abstract: PURPOSE:To enhance the dimensional accuracy and the reproducibility by a method wherein the titled device is formed in self-alignment by using only a method which can control the thickness of an oxide film or the diffusion length with high accuracy. CONSTITUTION:An oxide film 2 is formed on an N type Si substrate 1, an Si nitride film 3, a polycrystalline Si layer 4 doped with high concentration boron, and an Si nitride film 5 are formed thereon. Next, the nitride film 5 and the Si layer 4 are selectively etched by photoetching, thus forming an emitter-forming region 6. Then, an oxide film 7 is formed by oxidizing the side part of the crystal Si film 4. This oxidation is carried out in oxygen containing steam, resulting in the formation of the oxide film 7. The whole surface is coated with polycrystalline Si doped with no particular impurity, and a polycrystalline Si layer 8 is formed so as to cover the emitter region by removing the unnecessary part by photo etching. The nitride film 5 is etched in the exposed part, and the part under the polycrystalline Si film 8 is removed by overetching.

Title: Developing device and electrophotographic printing device
Inventor: ELLIOT A EKLUND
IPC: G03G15/08
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To prevent the toner contamination of an electrode caused by the dielectric breakdown of the air, and to prevent generation of image defect, by installing a power source controller communicated with a power source, and adjusting an electric bias of an electrode member. SOLUTION: The AC voltage applied between a wire 90 and a donor roller 42 by an AC power source 104, forms the toner cloud 112 in a developing zone 300. A power source controller 200 is operated in three modes, to prevent the dielectric breakdown of the air causing the wire contamination. In the first mode, the power source controller 200 cuts off the AC voltage to the wire 90 during the tone removement and in the initial retone. In the second mode, the power source controller 200 limits the electric current between the wire 90 and the donor roller 32 by the predetermined maximum transmittable electric current of less than the electric current threshold value of the wire contamination. In the third mode, the power source controller 200 adjusts the peak AC voltage, for continuously keeping the constant electric current between the wire 90 and the donor roller 42.

Filed: 1980-08-21
Abstract: PURPOSE:To preform an abnormal amorphous electromagnetic material inferior in the magnetic properties into the substance having specified magnetic properties, by grinding the amorphous metal sheet manufactured by single-roll cooling in the atmospheric air. CONSTITUTION:For instance, in case where the molten amorphous alloy of Fe-B- Si is made into a sheet of amorphous electromagnetic material chilled and solidified after jetted from a nozzle on the surface of a cooling roll rotating with high speed in the atmospheric air, sheets with low magnetic permeability and inferior in the magnetization properties are sometimes produced among those with high magnetic permeability and low iron loss owing to some fluctuation in the manufacturing conditions.

Title: Monitoring apparatus for abnormality of stationary leakage oil
Inventor: FUKUDA HIROHARU
IPC: G06T7/00
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a monitoring apparatus by which a stationary leakage oil can be detected at an early stage by a method wherein a camera is changed over in a monitoring exclusion state when two continuous images are changed, a monitoring area is reset when the monitoring exclusion state is returned between a previous monitoring operation and a current monitoring operation and a warning is displayed when an abnormality is generated in the stationary leakage oil. SOLUTION: An image changeover part 2 controls a plurality of image signals imaged by a plurality of cameras 1 so as to be changed over sequentially. A CPU 5 judges whether a change exists between two continuous images. When the change exists, a normal monitoring state or a monitoring exclusion state is judged on the basis of the operation of a human-body detecting sensor 24 in a monitoring area. In the normal monitoring state, a change state between the two images is monitored. In the monitoring exclusion state, the image signals are changed over to an image signal by a next camera 1. Whether a return operation to the normal monitoring state from the monitoring exclusion state exists between a previous monitoring operation and a current monitoring operation exists is judged.  When the return operation exists, the monitoring area is reset, and whether the abnormality of a stationary leakage oil inside the monitoring area exists or not is judged by an image processing board 5a. When the abnormality exists, an abnormality warning is displayed on a CRT 3. Thus, whether the abnormality of the leakage coil exists or not can be monitored at high frequency.

Abstract: PROBLEM TO BE SOLVED: To use a communication section until the set time by installing a battery residual capacity detecting means, power consumption setting means for the communication means and an additional function means, and a timesetting means for setting the time for the communication means to be kept in a usable condition. SOLUTION: In this system, a time-setting section 107 sets the duration the system uses for a communication section 102 and transmits the set time to a CPU 101. Then, the CPU 101 calculates the power necessary to use the communication section 102, until the set time based on a power consumption value per unit time set in a communication section power consumption setting section 108, a power consumption value set in an additional function section power consumption setting section 109, and the time counted by a time-counting section 110. Furthermore, the CPU 101 compares the calculation result with a battery residual capacity obtained, based on the calculation result and judges whether the communication section 102 can be driven until the set time.  In the case that the battery residual capacity is smaller than the calculation result, the CPU 101 calculates the longest possible time to use the communication section 102, based on the present battery residual capacity and notifies it. By this method, the communication section can be used until the set time.
