Title: Volumetric flow meter incorporating vibration reducing mechanism
Inventor: KITANO AKITOSHI
IPC: G01F3/10
Filed: 1979-02-09
Abstract: PURPOSE: To secure maintenance of the high accuracy for a long period of time without receiving the effect of the vibration and the impact caused by the engine or the like, by bearing the inner barrel storing the rotor for measurement of the flow amount via the buffer component.  
     CONSTITUTION: Inner barrel 3 of the fuel cost meter attached to frame 4 of the car is connected via, for example, synthetic rubber tube 11 to the fuel pipe 10 which is born within outer case 5 via buffer component 7 and then connected to the inflow opening and outflow opening 9 of barrel 3 of the flow meter as well as the inlet and outlet of case 5 each. Then rotor 1 such as a pair of oval gears or the like which is used for measurement of the flow amount is mounted rotatably to barrel 3 via axle 2. As a result, the vibration and the impact caused at car frame 4 by the high-speed rotation of the engine or the like can be reduced via tube 11 and buffer component 7, and thus are not transmitted directly to barrel 3. Thus the instrumental error performance can be maintained constant for a long period of time and without impairing the measuring function.

Title: Voiced sound/semivoiced sound symbol processor for japanese word input device
Inventor: KIMURA MITSUHIDE
IPC: G06F3/02
Filed: 1989-01-23
Abstract: PURPOSE:To improve the operability of a Japanese word input device and to attain the highly efficient input of Japanese word sentences by adding a storage means, an erasion means which works in response to a prescribed input operation, and a change means into a control part. CONSTITUTION:A control part 2 consisting of a microcomputer includes a storage means 3, an erasion means 4, and a change means 5. The KANA (Japanese syllabary) character strings are inputted via a keyboard 1 and stored in the means 3. The means 4 excludes the voiced sound symbols or semivoiced sound symbols out of those KANA character strings stored in the means 3 when other voiced sound or semivoiced sound symbols of the same kinds are added to those stored in the means 3 for correction of the KANA character strings into the normal ones. The means 5 changes the KANA character strings into those that contains the voiced sound or semivoiced sound symbols of the different types when these symbols are added to the characters of the same type. For instance, a semivoiced sound symbol 'PA' of 'OPAASAN' into 'BA' and therefore 'OBAASAN' is displayed on a display device 6. As a result, just a single operation of a cancel/correction key suffices and the operability of correction is improved.

Filed: 1989-01-24
Abstract: PURPOSE:To obtain a DC voltage which a time till it reaches a normal state is short and which does not have a ripple by installing multiplying type DAC which introduces the output voltage V of an operational amplifier as a reference voltage, which introduces the count value N1 of a counter and which outputs a signal proportional to N1.V. CONSTITUTION:The multiplying type digital/analogue converter DAC 6 is inserted into the feedback circuit of the operational amplifier 5, and the output current Iout of multiplying type DAC 6 is added to the inversion input terminal of the operational amplifier 5. The output current Iout is set to flow into a reference voltage generator 4 via a resistance R1. Namely, the output current Iout of multiplying type DAC 6 is equal to Ir. Multiplying type DAC 6 introduces the output voltage V of the operational amplifier 5 as the reference voltage, introduces the digital signal N1 which is in inverse proportion to the frequency fx of a measured signal, the multiplication is executed and the signals are outputted. Thus, the DC voltage which is proportional to the frequency fx without the ripple can be obtained immediately after the count result of one period is obtained.

Filed: 1984-01-31
Abstract: PURPOSE:To provide a regenerable desiccant generating no dust and having a fast drying speed, obtained by hermetically sealing a cellulosic nonwoven fabric dehydrated by dry heat treatment in a bag made of a gas impervious film. CONSTITUTION:A nonwoven fabric comprising a cellulosic fiber is subjected to dry heat treatment to dehydrate adsorbed moisture while the dried one is hermetically sealed in a bag made of polyvinyl chloride to prepare a desiccant. In using the desiccant, one end of the bag is cut off or the cellulose nonwoven fabric is taken out of the bag and put in a container such as a gas impervious can along with an article to be dried. Because this desiccant does not become powdery during use, it can be used in a state directly contacted with the article to be dried and, therefore, shows a high drying speed. After use, if dry heat treatment is applied to said desiccant at 110 deg.C for about 2hr, the desiccant is regenerated through the dehydration of adsorbed moisture and can be used repeatedly.
