Title: Unidirectional converter for surface acoustic wave
Inventor: SHIMIZU YASUTAKA
IPC: H03H9/02
Filed: 1979-02-13
Abstract: PURPOSE:To enable to oscillate surface acoustic waves only unidirectionally, by using the speed change of surface acoustic waves by DC magnetic field. CONSTITUTION:The reed screen electrodes 2A, 2B are formed on the magnetic substance board 1, and the piezoelectric film 3 is formed on it. Further, to the desired propagation direction P on the board 1, DC magnetic field H is fed with a  slope. With this constitution, taking the frequency propagating on the board 1 as f,  wave length as lambda, and velocity as V, V=flambda is established. Since DC magnetic field  H is fed, the velocity of surface acoustic waves toward desired propagation P is  changed to V1, and the velocity of propagation direction Q is changed to V2 respectively and V1not equal to V2 is obtained. Thus, the frequency toward P is f1=v1/lambda, and the  frequency of propagation direction Q is as f2=V2/lambda, and consequently, excitation is  made with the resonant frequency f1 of desired propagation direction P, then surface acoustic waves are toward P to increase the energy conversion efficiency between electric and acoustic waves.

Title: Water level display method in pumping plant
Inventor: UMEZAWA SOHEI
IPC: G09G5/02
Filed: 1994-02-08
Abstract: PURPOSE:To accurately enable the visual confirmation of a water level fluctuation state at a glance by forming a frame of an internal water level and internal water level rising speed on a screen of display operation in a vertically stacked state and classifying the interior of the frame by color across the reference value of the internal water level rising speed. CONSTITUTION:The interior of a frame F is classified by color across zero being the reference value of internal water level rising speed V so that the region DZ on the plus side of the frame F is set to a red color and the region SZ on the minus side thereof is set to a green color. Since the present water level state is displayed by both of the area surrounded by the frame F and the classification by color, an operator can grasp the danger degree of the water level state at a glance. For example, when the frame F becomes large and the present water level H exceeds a start water level, the operator starts the operation of a pump. When the almost all regions in the frame F become the green region SZ even in this case, it is cleared that the inner water level rising speed is present on one side and, therefore, it is unnecessary to immediately increase drainage capacity and operation is performed so as to set the operation number of pumps to the necessary min.

Title: Large size low-speed two-cycle engine
Inventor: YOSHIHARA SADAO
IPC: F02P21/00
Filed: 1990-01-26
Abstract: PURPOSE:To keep off any drop in reliability due to low cycle fatigue by preheating such a member as forming a combustion chamber at time of an engine being on standby, and even at time of engine stoppage, keeping the same temperature level or the like as at time of engine driving, while relieving a stress fluctuation due to rapid load charging. CONSTITUTION:When such a standby command 9 that makes an engine possible for rapid load charging all the time is given, a preheated gas exhaust valve 3 is opened, while a valve 5 is opened as well by a controller 4. Then, fuel gas 6 is fed to a preheater 2 from this valve 5, whereby a preheated gas flame 2a is sprayed to the inside of a combustion chamber 7, heating a combustion chamber forming member Z. At this time, temperature in this combustion chamber 7 is measured by a temperature sensor 8. In consequence, when temperature goes up, opening of the valve 5 is reduced, throttling the preheated gas flame 2a, and when the temperature goes down, the opening of the valve 5 is enlarged, keeping the combustion chamber forming member Z into the same level as in an engine driving state and a temperature gradient. On the other hand, combustion gas 2b is exhaust out of the preheated gas exhaust valve 3.

Title: Image reading device
Inventor: TAKAGI KOSUKE
IPC: G06T1/00
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To restrain the missing of feed due to a separation mechanism so as to be able to stably read out an image by rotably mounting an elastic roller circumferentially contacting with a separation roller on a rotary shaft reversely rotating so as to return a document from the carrying direction. SOLUTION: When a document 3 is delivered in the carrying direction M by a paper feed roller 5 and approached to a separation mechanism, the extreme end part of the document 3 is contacted with an elastic roller 23 outside a retard roller 7 reversely rotating. The elastic roller 23 is rotatable against a rotary shaft 19, and it is rotated in the direction feeding the document 3 in the carrying direction M together with a separation roller 6, because it is pressure contacted with the separation roller 6. Hereby, force in the direction of feeding forward is applied to the extreme end part of the document 3. Further, even when paper powder is stuck to the separation roller 6 and the retard roller 7, and friction coefficients of both roller become the same level, the contact pressure of the separation roller 6 is larger by pressure due to deformation of the elastic roller 23, and hence the document 3 is stably sent out in the carrying direction M.

IPC: B65G51/02
Filed: 1978-02-15
Abstract: PURPOSE: To promote the efficiency of the transportation abandonment of snow, by remarkably shrinking the volume of snow by changing snow into columnar snow lump by compression modling snow, by charying the snow lump into a piping and by feeding the snow lump by pressure.  
     CONSTITUTION: Snow is charged into a box doby 5, and columnar snow lump 2 is formed by compressing the snow by means of a cylinder 8. An opening and closing valve V 1  is opened to shape a duct, and the snow lump is fed into a piping 3 by means of a cylinder 11 and mixed with an air current. The snow lump 2 advances by thrust by the air current, continuously travels by inertia after the snow lump passes through an opening portion of an intake pipe 17, passes through a valve V 2  beforehand opened and approaches to a valve V 3  beforehand closed. As soon as the snow lump passes through the opening and closing valve V 2  the valve V 2  is closed, and the third opening and closing valve V 3  is opened. Thus, the snow lump can economically be transported at high speed because the coefficient of friction between the snow lump 2 and the piping is small.
