Patent JP-S60178624-A (JP)
Title: Charged-particle beam drawing device
Inventor: SUZUKI TOMEO
IPC: G03F7/20
Filed: 1984-02-24
Abstract: PURPOSE:To compensate the positional error of a stage in a short time by holding a signal corresponding to a difference between the aimed position and actual position of the stage to a first register and setting a minute positional compensating signal to a second register at all times in response to minute variation. CONSTITUTION:The movement of a stage 6 is set to a counter 8, and compared with the value of a register 10, to which set movement is set from a controller 9, by a comparison circuit 11. A difference signal between both movement is transmitted over a first register 14 and a first arithmetic circuit 15. Said first arithmetic circuit 15 compares the difference signal and a signal held to said first register 14, and generates a difference signal between them. Said difference signal is held to a second register 16. A signal held to a register 17 and the signal held to said first register 14 are transmitted and added to a second arithmetic circuit 18, and the signals are compensated so as to reduce the effect of deflection distortion in response to the intensity of the signals. The signals are added to the signal held to the second register 16 in a third arithmetic circuit 19, and added to a deflector 4.

Title: Vacuum cleaner
Inventor: SAITO KAZUO
IPC: A47L9/00
Filed: 1991-02-28
Abstract: PURPOSE:To suppress the exhaust resistance at the time when exhaust passes through a filter, and to prevent the reduction in suction force of the cleaner by operating a shutter so that exhaust of the cleaner passes through a first opening part, in the case a function of the filter is unnecessary. CONSTITUTION:When the cleaner is operated in a state that a first opening part 9 is closed by operating a shutter 12, exhaust of the cleaner passes through a dust collecting chamber 3, a motor-driven air blower containing chamber 4 and a deodorizing filter 10 and eliminates a nasty smell of the exhaust, and is exhausted from an exhaust port 7. On the other hand, when the cleaner is operated in a state that a first opening part 9 is opened by operating the shutter 12, exhaust of the cleaner flows in the direction in which exhaust resistance is small, therefore, it passes through a dust collecting chamber 2, a motor- driven air blower containing chamber 5 and a first opening part 9 and is exhausted from the exhaust port 7. In the case a nasty smell of exhaust of the cleaner does not weigh on a user's mind, when exhaust of the cleaner is not allowed to pass through the deodorizing filter 10 but is allowed to pass through a first opening part 9, the exhaust resistance becomes small, and suction force of the cleaner does not deteriorate.

IPC: B23K11/06
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce welding time and to control welding speed arbitrarily by using an inverter type DC power source which supplies a DC current consisting of a pair of positive and negative pulses during the time for energizing a welding zone. SOLUTION: A weld zone of a package is welded by roller electrodes to which a current is supplied from an inverter type DC welding power source.

Then, this nugget 35 is cooled for 2ms. Accordingly, it is possible to reduce the welding speed to one tenth compared with that of a conventional single phase DC welding power source. As a result, the inverter type DC welding power source enables various welding conditions to be arbitrarily controlled such as pulse width, welding current and pulse spacing; it is also capable of feedback control.

Filed: 1990-02-15
Abstract: PURPOSE:To detect abnormalities for any combination of wire breaks by providing an amplitude-level detecting circuit, an abnormal-amplitude-decrease detecting circuit and an abnormal-amplitude-level-increase detecting circuit. CONSTITUTION:An amplitude-level detecting circuit 21 detects the amplitude of a phase modulation signal. An abnormal-amplitude-level decrease detecting circuit 22 generates a wire break signal when the detected amplitude of the circuit 21 is smaller than a specified reference value. The reference value is set at a value smaller than the amplitude of the phase modulation signal when there is no wire break in the connecting wire of a coil wound around a salient pole. An abnormal-amplitude-level-increase detecting circuit 3 generates a wire break signal when the detected amplitude of the circuit 21 is larger than the specified reference value. The reference value is set at a value larger than the amplitude of the phase modulation signal when there is no wire break in the connecting wire of a coil wound around the salient pole. The wire breaks in all combinations which are liable to occur in practical applications can be detected with both the circuit 3 which detects the abnormal increase in detected signal of the magnetic resolver and the circuit 22 which detects the abnormal decrease.

Title: Building having snow blowing-out effect
Inventor: NISHIKAWA KAORU
IPC: E04H9/16
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the accumulation of plowed snow under the eaves by installing the flat sliding surface of a roof in parallel with prevailing wind and providing a bent part in a position below the wind. SOLUTION: A flat sliding surface 1 is disposed in parallel with the direction of prevailing wind in a land for constructing a building A and this is composed of a curved surface. A bending curved surface 2 is formed in the lower end part of the slope of this flat sliding surface 1, that is, under the eaves in the wind side, so as to be bent by an angle of 23 degrees or lower with respect to a horizontal surface. By forming the bending curved surface in the eaves in the wind side, this bending curved surface 2 acts as a flow-rectifying fin, and wind flowing down along the flat sliding surface 1 is flow-rectified to be upward by a fixed angle in the bending curved surface 2. Thus, the snow of the roof is kicked upward in the bending curved surface 2 and the snow is blown out by a fixed distance without falling under the eaves of the roof.
