IPC: B05C5/00
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a coating apparatus capable of reducing the use amt. of a coating soln. SOLUTION: The resist soln. supplied to the almost center of rotation of the glass substrate G held by a spin chuck 28 is spread toward the outer periphery of the glass substrate G by a spreading bar 76. That is, since centrifugal force is not used, the resist soln. can be applied to the entire surface of the glass substrate G rotated at a low speed without being rotated at a high speed. The spreading bar 76 is made of, for example, a plastic and extends in a curved state toward the outer periphery of the glass substrate while approaches the glass substrate G held by the spin chuck 28 so as to leave a predetermined interval, for example, of about 0.2-0.5 mm.

Title: Filter panel for range hood
Inventor: SHIMONO KIKUO
IPC: F24F7/06
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To enable an increase in the longitudinal size of a filter panel while preventing filtration capability from being lowered by coupling a separate filter panel with an upper edge of a filter panel and one of a lower end or both of the same through a coupling tool in a flat plate manner and matching them with the longitudinal size of a filter mounting hole in a range hood. SOLUTION: When a filter panel indicated at a right lower portion in the figure is mounted in a range hood 1, once an air fan 14 is driven, lower contaminated air is sucked into the range hood 1 through upper and lower panels B, A and is exhausted to the outside. An auxiliary panel B can be mounted on a lower frame 8 instead of its being mounted on an upper frame 4. There may be further mounted the auxiliary panel B on both of the upper frame 4 and the lower frame 8. When there are prepared as the auxiliary penels B several kinds of them having different longitudinal sizes L3, an application range is expanded. A coupling tool or an auxiliary piece 5 is mounted on one of the upper frame 4b and the lower frame 8 or on both of them to ensure fine adjustment of the longitudinal size. Hererby, a desired size filter panel is ensured.

Title: Nozzle unit for vacuum cleaner
Inventor: SASADA KIMIO
IPC: A47L9/02
Filed: 1993-10-28
Abstract: PURPOSE:To enhance the mobility of a nozzle unit body and to enhance the cleaning workability by forming suction ports in the lower part of the outer periphery of the nozzle unit body on opposite sides of the latter, by rotatably forming rotary members having several small holes in the outer peripheral part of the nozzle unit body on opposite sides of the latter. CONSTITUTION:Rotary members 8 are rotated, integrally with wheels 7 mounted at opposite ends of a nozzle unit body 1. Each of the rotary members 8 is net-like so as to have a high frictional resistance with respect to a surface to be cleaned. Since the wheels 7 and the rotary members 8 abut against the surface to be cleaned so that the wheels 7 and the rotary members 8 are rotated in association with the movement of the nozzle unit body 1, due to the friction with respect to the surface to be cleaned. Since the rotary members 8 get contact with ring-like ribs 6 formed on the nozzle unit body 1 so as to be rotated, the frictional resistance with respect to the nozzle unit body 1 is reduced so as to enhance the mobility of the nozzle unit body 1. Since the wheels 7 and the rotary members 8 are pivotally journalled at opposite sides of the nozzle unit body 1, independent from each other. Thus it is possible to easily change the moving direction. Further, the diameter of the wheels 7 is greater than that of the rotary members 8 so as to prevent the end parts the rotary members 8 from catching on the surface to be cleaned.

Filed: 1990-10-08
Abstract: PURPOSE:To prevent a sump pocket from occurring in the space between a ball valve spherical peripheral surface and a body inner surface by installing a seal, covering the whole spherical peripheral surface of a ball valve. in the body inner surface, and constituting this seal with fluororesin. CONSTITUTION:A seal 3 is interposed between an inner circumferential surface of a body 1 and an outer circumferential surface of a ball 2, and a link-form seal 5 is interposed between two parts 3a, 3b of the seal 3 which consists of fluororesin, and is fitted in and locked to a specified position of the inner circumferential surface of the body 1. Since an interval between the ball valve 2 and the body 1 is sealed by the seal 3 and two ring seals 4a, 4b, even in the case where the ball valve 2 is closed, a liquid collected in a through-hole 2b is prevented from entering the space between the spherical outer circumferential surface of the ball valve 2 and the inner circumferential surface of the body 1. In addition, since a friction factor of the seal 3 is small, the ball valve 2 is rotatable very smoothly.

Abstract: PURPOSE:To obtain a tripple-barrier resonating tunnel diode, characterized by a large peak current and an excellent peak to valley ratio, by making the energhy at the lower end of one conduction band of two quantum well layers less than an N-type layer at both ends of a barrier by a specified value. CONSTITUTION:On a semi-insulating GaAs substrate 59, the following layers are sequentially grown: an N<+>-GaAs contact layer 75; an N-GaAs layer 74; a GaAs spacer layer 71; an AlAs barrier layer 73; a GaAs quantum well layer 71'; an AlAs barrier layer 73, an InGaAs quantum well layer 72: an AlAs layer 73''; a GaAs spacer layer 71''; an N-GaAs layer 74'; and an N<+>-GaAs contact layer 75'. Then the growing layers other than a diode region are etched away. Finally ohmic electrodes 10 and 10' are formed. At this time, the energy at the lower end of the conduction band of the quantum well layer 72 at thermal equilibrium is made less than that at both ends of the barrier by E'. The bottom level E1 of the quantum well layer 71' and the bottom state E1' of the quantum well layer 72 are made to be at the equal energy by the application of a voltage. Thus an excellent resonance state is obtained.

Title: Coaxial waveguide converter for orthogonal two polarized waves
Inventor: HOZUMI ICHIRO
IPC: H01P1/161
Filed: 1986-11-14
Abstract: PURPOSE:To improve the isolation by arranging the mutual position of 1st and 2nd monopole antennas in a main waveguide so as to be T-shaped form subjected to equi-potential excitation electrically. CONSTITUTION:The 2nd monopole antenna 4 is arranged to a position of a length of nearly l/2 (l is the length of the 1st monopole antenna 3 projected in the main waveguide 2) so as to be orthogonal in T-shape without being in contact with the tip. Further, the 1st monopole antenna 3 is positioned to the main waveguide 1 so that the impedance toward both directions from a position of nearly l/2 long is made nearly equal to each other. Thus, even if the signal inputted from one monopole antenna is induced in the other monopole antenna, since the potential is the same in the level nearly in opposite direction, they are cancelled together and the isolation of both coaxial parts 5, 6 is improved.

Abstract: PROBLEM TO BE SOLVED: To obtain a noise filtering method in which a noise at a frequency band identical to that of ultrasonic waves can be filtered out surely by a method wherein peak values of respective waveforms by detecting and recording a specific signal a plurality of numbers of times are compared at a prescribed timing and a minimum value is extracted. SOLUTION: A specific signal S from which a noise is to be filtered out is detected a plurality of numbers of times, e.g. twice, and waveforms of respective detected signals S1, S2 are recorded. Then, peak values of the respective waveforms of the respective detected signals S1, S2 are compared at a prescribed timing, a minimum value is extracted, and a signal S4 is obtained. In the signal S4, a minimum peak value out of effective components e1, e2 which are generated in the respective detected signals S1, S2 at an identical timing, i.e., the effective component e2, is left. In addition, noise components a1, a2 in the respective detected signals S1, S2 are generated at different timings.  As a result, when the noise components a1, a2 are compared at an identical timing so as to extract the smaller noise component, a peak value 0 in which the noise components a1, a2 are not contained is extracted, and the noise components a1, a2 are filtered out.
