Title: Vibration gyroscope
Inventor: NAKAMURA TAKESHI
IPC: G01C19/56
Filed: 1988-08-12
Abstract: PURPOSE:To increase an output voltage generated by arranging a vibrator to vibrate being bent orthogonally to a main surface of a piezo-electric element for driving while a piezo-electric element for detection is provided on a side thereof having a main surface orthogonal to a direction of vibration. CONSTITUTION:When a drive signal is applied between piezo-electric elements 18 and 20 for driving, a vibrator 12 vibrates being bent and support members 22 and 24 are formed at a node point thereof. Here, when a vibration gyroscope 10 rotates on the axis thereof, a Coriolis force works orthogonally to the vibrator 12 to cause a change in the direction of vibration thereof. At this point, the vibrator 12 has a side existing with a main surface thereof almost orthogonal to the direction of vibration. When piezo-electric elements 14 and 16 for detection are provided on the side, the element 16 makes a curvature movement nearly orthogonal to the main surface, and the element 14 nearly parallel therewith. Thus, a voltage generated between the elements 16 and 14 becomes larger than that when the gyroscope 10 does not rotate. Transverse surfaces of the vibrator 12 are polygonal and 3 or more than 4 in number.

Abstract: PURPOSE:To reduce strain and noise of higher order by >=3 magnetic poles  which precede and trail a magnetic recording medium. CONSTITUTION:The 2nd magnetic pole 44 has height greater than the width of a magnetic tape 1 to be erased as well as the 1st magnetic pole. The magnetic pole has the opposite polarity to the 1st magnetic pole and less magnetic pole intensity than the 1st magnetic pole, and also has a greater value than the coercive force of a tape to be erased. The final magnetic pole 45 where the tape 1 comes into contact finally is composed of plural magnetic pole elements in a tape widthwise direction. Magnetic poles 46-50 have intensity nearly equal to or less than that of the 2nd magnetic pole 44. The final magnetic pole 45 is so constituted by stacking previously magnetized magnet plates that magnetic poles N, S, N- appear on a tape sliding surface.

Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To use a memory for image data in an information processing part as a video memory for interpolating a video signal omission period by supplying a driving signal for reading out a signal from an image pickup part to an imaging device, and processing the signal output of that imaging device. SOLUTION: An element driving circuit 103 supplies the driving signal for reading out a signal to an imaging device 102 and when that imaging device 102 is operated for double exposure time in comparison with ordinary time, the video signal of the imaging device 102 is turned into intermittent signal for every frame. While a video signal 105 is outputted, a discriminate signal 106 from an image pickup part 101 outputs 'H' to a memory control circuit 111. On the basis of a vertical synchronizing signal 107, the memory control circuit 111 writes the video signal 105 from a signal processing circuit 104 into an image memory 109. When the discriminate signal 106 is 'L', on the other hand, the memory control circuit 111 repeatedly reads out video data written in the image memory 109 for the preceding frame.

Abstract: PURPOSE:To prevent hot air out of a main body of a refrigerator from entering the main body of the refrigerator through a water drain passage by a method wherein a defrosting water discharging passage disposed at the main body of the refrigerator is provided with porous water absorption material so as to close an interior part of the water drain passage. CONSTITUTION:Porous water absorption material 27 is inserted into a lower end 21a where a water drain pipe 21 is projected into a machine chamber 23 and disposed to close is. The porous water absorption material 27 is formed by an evaporator having hydrophilic synthetic fibers bundled, for example. As a defrosting heater 19 is electrically energized to perform a defrosting operation, frosts in a cooling device 13 is melted. The water i.e., the defrosted water is flowed down through a water drain passage 22. The defrosted water immerses in sequence into the porous water absorption material 27 as it is reached to the porous water absorption material 27. As its water inclusive amount reaches its saturation value, volume of water supplied to the porous water absorption material 27 is outputted from the porous water absorption material 27 and flowed down into an evaporating pan 24. Accordingly, water is always contained in the porous water absorption material 27 and the hot air out of the main body of the refrigerator does not flow into the main body 1 of the refrigerator through the water drain passage 22.
