Title: Gate circuit
Inventor: NAKASHIMA MASAHIKO
IPC: H03M1/12
Filed: 1978-04-06
Abstract: PURPOSE:To reduce the power consumption by connecting the emitter follower to the inverse input, the noninverse input and the output of the differential amplifier each and using the emitter of the output emitter follower as the output terminal to feed back the inverse input. CONSTITUTION:Emitter followers EF of Tr9 and 10 are connected to the noninverse input and inverse input of the differential amplifier comprising transistor  Tr4, 5, 7 and 8, and EF (Tr13) is connected to the output of the differential  amplifier. The emitter of Tr13 is connected to output terminal 2, and the feedback  is given to Tr10 connected to the noninverse input terminal through terminal 2.  The input signal of terminal 1 is obtained in the form of the output signal of the  same phase as terminal 2. And with application of the gate signal to gate signal  terminal 3, the current flows to Tr14. Then Tr13 and 14 function as EF. When  the current of terminal 3 becomes 0, all Tr's are turned off with no current flowing  to terminal 2. And the gate circuit is turned off. As the output current flows in the  necessary amount via Tr13 and 14, the supply of a large amount of current is not  always required. Thus, the power consumption can be reduced.

Title: Ink jet recording device
Inventor: MIURA MASAYOSHI
IPC: B41J2/065
Filed: 1981-03-19
Abstract: PURPOSE:To simply form a multinozzle head with reduced cost by a device wherein an ink jetting port is shaped into the form of a slit, thereby to facilitate positioning between the ink jetting port and air jetting ports. CONSTITUTION:An ink jetting port is shaped into the form of a slit. Meniscus 19 of ink occurring at the boundary surface between an ink slit 17 and an air layer 12 has the concave surface, because ink is pressed toward an ink chamber 7 due to higher air pressure at points B1, B2 than that at points A1, A2, A3. By properly adjusting the balance between ink pressure and air pressure, it is possible to generate undulations at intervals of air jetting ports 13 on the meniscus 19 of ink opposite to the ink slit 17. Even with an ink jetting port being in common, ink droplets can be independently jetted from the respective air jetting ports 13 and stopped, if the air jetting ports 13 and electrodes 14 are formed in the independent states.

Abstract: PURPOSE:To inexpensively obtain a large sized picture surface having a picture quality as good as the picture quality of CRT by constituting a nonlinear resistance element to be used for switching of a two terminal element comprising a conductor/calcined film of metal alkoxides/conductor, wherein said calcined film is obtd. by calcining a mixture of plural metal alkoxides after coating the mixture. CONSTITUTION:A nonlinear resistance element to be used for switching is constituted of a two-terminal element consisting of a conductor/calcined film 2 of metal alkoxides, and a conductor, wherein said calcined film 2 of metal alkoxides is formed by calcining a mixture of plural kinds of alkoxide after coating it. Thus, the steepness of current/ voltage characteristic is eliminated, difference between polarity is also eliminated, and pinholes of only about several tens Angstrom  diameter are formed in the calcined film 2 of a mixture of metal alkoxides, so short-circuiting between a picture element electrode 1 and a scanning electrode 3 is inhibited, and a dielectric constant of the calcined film 2 of a metal alkoxides mixture is obtd. Thus, fast response speed is realized and driving under small electric power consumption has become possible. Moreover, the size of an active element can be enlarged. By this constitution, a picture image having picture quality as good as that of CRT is obtd. at low cost, and enlargement of picture size is also possible.

Filed: 1992-02-27
Abstract: PURPOSE:To obtain structure, in which an effective overlapping area between internal electrodes is difficult to be varied, by composing one of the internal electrodes of first and second isolation electrodes and the other of non- connection type internal electrodes. CONSTITUTION:First and second isolation electrodes 15, 16 extended from end faces 12a, 12b to the central side so as to be electrically connected to external electrodes 13, 14 are formed into a sintered body 12. A non-connection type internal electrode 17 is formed separated from the first and second isolation electrodes 15, 16 and ceramic layers 12c. The non-connection type internal electrode 17 is constituted in a rectangular shape, and arranged so as to be superposed to both the first and second isolation electrodes 15, 16. Accordingly, even when the positions of the formation of the first and second isolation electrodes and the non-connection type internal electrode are displaced slightly, the varying section of the overlapping areas of the internal electrode is offset mutually, and dispersion can be reduced extremely, thus inhibiting a resistance value at a small value.

Title: Liquid crystal element
Inventor: YAMAGUCHI MASAHIKO
IPC: G02F1/137
Filed: 1988-02-24
Abstract: PURPOSE:To execute a display having a high contrast, a wide visual angle, and also a more achromatic color by setting a retardation and a twist angle to a specific range. CONSTITUTION:A retardation is set to a range of >=1.4 and <=2.2. In this regard, the retardation is a value which has multiplied a refractive index anisotropy DELTAn at a room temperature of a liquid crystal and the maximum distance (cell gap) (d) between transparent electrode substrates, and when this retardation becomes under 1.4, the contrast and the visual angle dependency are not improved enough, and coloring of the display is not improved enough either. On the other hand, when the retardation exceeds 2.2, even if the liquid crystal of DELTAn=0.22 whose refractive index anisotropy is the largest among the liquid crystals which have been put to practical use is used, it is necessary to set the cell gap (d) to >=10mum, and such inconveniences as a temperature dependency of the liquid crystal element and a threshold voltage become high and the responsiveness is deteriorated are generated. Therefore, a twist angle of the liquid crystal can be set within a range of 60-150 deg. or so. In such a way, a high contrast is obtained, the visual angle dependency is improved, and an achromatic color is obtained.

Filed: 1989-02-23
Abstract: PURPOSE:To obtain a high quality audio output by controlling an adaptive filter in a direction where the adaptive filter attenuates a low frequency component when the level of the low frequency component is small and the level of a high frequency component is large. CONSTITUTION:An output of an FM demodulator 13 is fed to a low frequency detection circuit 17 and a high frequency detection circuit 18 and the low frequency detection output and the high frequency detection output are inputted to a control circuit 19. The control circuit 19 outputs a control signal Vc in response to the state of the level of the low and high frequency components and gives the signal to a characteristic control terminal of an adaptive filter 14. When the level of the low frequency component is small and the level of the high frequency component is large, the adaptive filter 14 controls the adaptive filter 14 in a direction attenuating the low frequency component. Thus, the low frequency component including a low frequency noise is automatically attenuated under the condition where the low frequency noise is outputted with amplification and a high quality audio output is obtained.

Moreover, it is desirable, from the durability improvement point of view, that the average particle diameter of Al2 O3 , as abrasives, to be 0.02 to 1 μm. As a matter of fact, it is most desirable to set the diameter within the range of 0.05 to 0.7 μm.

Abstract: PROBLEM TO BE SOLVED: To improve degradation detecting sensitivity by the measurement of partial discharge and enable degraded points to be specified by irradiating a portion of a measured object with a pulse-like X ray in the partial discharge measurement to judge the presence of the partial discharge from the synchro nism between the X-ray irradiation presence signal and the partial discharge signal.

Also, pulse-line X-rays are emitted from an X-ray source 8 and the number of X-ray pulses is then measured through the X-ray source 8 and a signal cable 9 by a pulse measuring device 61. Thus, a signal can be detected directly from the IJB 3 having high possibility of degradation and the measurement can be performed with a high frequency band having small noises, so that the detecting sensitivity is improved. Also, the X-ray irradiation part is near the measuring part so that X-ray irradiation presence signal is easily transmitted and received.
