Title: Water tank filtering system
Inventor: NAKAMURA NAOTAKA
IPC: A01K63/04
Filed: 1997-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a filtering system in which a filtered water reservation part space can be cleaned without needing any complicated work for taking out fishes, filter, bottom spread net and filter holding panel or the like by providing a water pouring port on a filter holding part (such as bored panel) in the filtering system or filtering tub of water tank. SOLUTION: For example, a water tank 14 has a reserved water space 18 for cleaning with a filter holding panel 6 as a boundary and has a water pouring pipe 1 for cleaning the reserved water space 18. When cleaning the space 18, a filter 12 is moved away a little, a cap 19 for ordinary use is detached and a joint 2 is connected and linked to a water pouring hose 5. Next, when axial turns 3 are applied while pouring water, the water pouring pipe 1 cleans the whole filtered water reservation part space 18 beautifully by applying impulse force to water corresponding to the combination of surrounding obstacle conditions and axial turns 4. Muddy water can be completely discharged like an arrow 10.

Title: Field effect transistor equipped with vertical gate side wall and manufacture thereof
Inventor: BOYD DIANE C
IPC: H01L21/3065
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To enable a field effect transistor to be accurately specified in channel length, lessened in source and drain resistance, and minimized in overlap capacitance, by a method wherein a gate hole is demarcated on a dielectric stack, an attached side wall layer is removed from a horizontal plane, and the gate hole is filled up with a gate conductor. SOLUTION: An etching window which is nearly equal in lateral dimension to a gate pillar that is specified in dimensions by a resist mask is provided to a dielectric stack which comprises nitride layers 31 and 38. An RIE process for forming a gate hole is used for transferring the etching window to the dielectric stack. Then, the gate hole is demarcated-by an RIE method, a side wall layer is attached and then removed from a horizontal plane. By this setup, the gate hole is lessened in length by a residual side wall spacer 61. Then, polysilicon is deposited inside the gate hole and on a dielectric stack uppermost layer 38, and the dielectric stack uppermost layer 38 is exposed by flattening the deposited polysilicon.

Filed: 1991-01-31
Abstract: PURPOSE:To improve the characteristic by decreasing an interference between two coils of a quadrature coil by placing two each independent coils in which one and the other are formed in a loop type and an 8-shaped type, respectively, in such a positional relation as the magnetic field directions generated thereby are orthogonal. CONSTITUTION:When a current is allowed to flow to a horizontal magnetic field generation coil 6, an induced current is generated in a vertical magnetic field generation coil 5, and becomes the direction for negating each other as the whole loop of the coil 5. Also, when a current is allowed to flow to the coil 5, the current is induced to the coil 6, and becomes the direction for negating mutually at the time of viewing as the whole of the 8-shaped type coil 6. Therefore, at the time of generation of both vertical and horizontal magnetic fields, the current induced to one coil is negated mutually as the whole coil thereof and does not become that which executes one turn. Accordingly, an interference between two coils 5, 6 is eliminated, the independence is enhanced each other and the characteristic is improved.

In the lens microcomputer 10, a driver 4 is controlled based on these difference values, a diaphgram actuator 3 is driven, and thereby carrying out control. Here, each N system is different in field frequency, and the integrating cycles of an integrator 15 are 60Hz in NTSC, 50Hz in PAL and SECAM, whereby the time lags of AE control systems are changed and parameters in the control system are also changed. Thus, even as for cameras mutually different in the television systems, the signal systems can be discriminated, and lens control conforming to each system can be realized.
