Title: Rubber roll
Inventor: NISHIYAMA TADAO
IPC: F16C13/00
Filed: 1993-06-07
Abstract: PURPOSE:To prevent separation of rubber layers from each other and to lengthen a life span of a rubber roll by constituting the rubber roll of a roll core made of iron or ceramic and a rubber roll surface layer and providing a space part between the roll core and the surface layer and supplying compressed air to this space. CONSTITUTION:A wide rubber ring 1 is set at least wider than the width of a coating treatment material such as a steel plate on the outer periphery of an iron core 6 so as to secure the width of a roll and fixed with an end plate 2. The fixing method of end parts of the rubber ring 1 is to insert packing between the end plate 2 of the roll and an iron core end surface 6, the rubber ring 1 is fixed with a bolt and air in a hollow part is sufficiently sealed. Air 7 is filled between the iron core 6 and the rubber ring 1 from a nozzle 5, and air pressure in correspondence with used line pressure is made. Consequently, heat build-up inside rubber while the roll is used is lessened and even when the roll rotates at high speed, trouble of rubber separation is eliminated.

IPC: G01S3/14
Filed: 1982-08-06
Abstract: PURPOSE:To elevate the measuring accuracy preventing the lowering of accuracy due to noise of a flat part in a square wave by sampling only information at only rising and falling parts of the square wave on which bearing information is concentrated. CONSTITUTION:Outputs of antennas 1 and 2 perpendicular in the directivity to each other are added to a ballance modulators 3 and 4, modulated by outputs of two square generators 5 with a phase difference of 90 deg. and synthesized with a synthesization circuit 7 to make a synthesized output of non-directivity. The output is added to a frequency discriminator 11 through an HF amplifier 8 and an IF amplifier 10. The output of the discriminator is sampled each time a square wave rises and falls and the values thus obtained are applied to memory devices 17-20, outputs of which are added with an addition circuit 25 at each 1/4 cycle of the square wave to form a staircase. This is passed through a filter 26 and a phase detector 27 to detect the phase of a sine wave component thereby indication of the incoming direction of a radio wave with a display 28. As a result, errors due to a voice signal or the like is prevented thereby enabling accurate detection of the incoming direction of the radio wave.

Filed: 1978-11-07
Abstract: PURPOSE:To improve the F/B characteristics over a wide band by using the reactance circuit and the phase shifting cable and then designing them to the proper value in order to compensate the phase shift variation caused by the mutual interference among the radiation elements. CONSTITUTION:The unidirectional antenna is constituted with a pair of radiation elements 1 and 2 featuring the same characteristics and distributed in opposition with space d, compounding unit 5 which compounds the signals given from elements 1 and 2, reactance circuit 8 inserted into the area between element 1 and unit 5, and phase shifting cable 4 inserted between element 2 and unit 5 each. Thus either one of the feeding phases to the radiation elements is inverted, and the output given from unit 5 is supplied to the picture reciever. In other words, circuit 8 is inserted to feeder to element 1 to secure the characteristics in that the length of cable 4 is increased relatively in the low channel. As a result, the phase variation caused by the mutual interference can be compensated, thus improving the F/B characteristics over a wide band.

IPC: G06F21/10
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To easily recognize the existence of memory protect and to easily copy data stored in a semiconductor memory. SOLUTION: An address change detection part 1 detects whether an inputted address signal has no change longer than a prescribed time or not and when a change in the address signal is detected, a signal A-SUM is outputted. Address storage circuits 2 and 3 store arbitrary addresses and when the inputted address signal is coincident with a stored address in the state of supplying the signal A-SUM, signals A and B are outputted. Based on the change timing of signals A and B, signal generating circuits 4, 5 and 6 output a signal OUT.

Title: Mc type pickup cartridge
Inventor: YASUDA SHINJI
IPC: H04R9/16
Filed: 1979-10-24
Abstract: PURPOSE:To make it possible to attain the excellent efficiency of electric power generation by constituting a cartridge so that magnetic flux from a magnet can be led to a yoke properly. CONSTITUTION:While cantilever 2 is stationary, no magnetic flux flows to center yoke pole 10L2 of yoke 10L and no voltage is induced across coil 11L. When lever 2 is turned in the direction L1, yoke 10L is displaced, and consequently magnetic flux phi from pole piece 13 enters the other pole piece 14 by way of front yoke pole 10L1 and yoke pole 10L2 of yoke 10L, so that a voltage of one polarity will be induced across coil 11L. When it is turned in the opposite direction to L1, yoke L is displaced in the opposite direction to L1, yoke L is displaced in the opposite direction and a voltage of the opposite polarity is induced across coil 11L. Thus, since the magnetic flux can be led from magnet 12 properly, the electric power generation efficiency is improved and owing to lightweighted armature 3, response is improved.
