IPC: G02F1/133
Filed: 1986-03-12
Abstract: PURPOSE:To improve the quality of a gradation display by setting a data voltage of every gate line to a voltage waveform of a positive/negative symmetry. CONSTITUTION:At the time TA for addressing one gate line, a data voltage VD of a voltage waveform of a positive/negative symmetry is generated, and in a positive frame, a gate voltage Va is generated against a positive voltage waveform, and in a negative frame, the gate voltage Va is generated against a negative voltage waveform, and they turn on the gate, respectively. The gate voltage generation time Ta becomes half of TA. In such a way, in the positive and negative frames, positive and negative variation portions of a liquid crystal cell voltage VLC negate each other, its effective value goes to constant, and its value is determined by only a data voltage VD1 and VD2 being symmetrical to each other, and not influenced by the peripheral display pattern, therefore, the display quality is improved.

Title: Signal processing circuit of electronic endoscope
Inventor: HIGUCHI MITSURU
IPC: G02B23/24
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To compensate the shortage of quantity of light due to the response delay of a light shielding mechanism in an electronic endoscope which provides still pictures of high quality and moving pictures that faithfully reproduce movement. SOLUTION: For moving pictures, pixel-mixture signals are output from a CCD 12 in order to faithfully reproduce movement. For still pictures, signals of all pixels obtained with the CCD 12 through one exposure are read as a light-shielding period set by a light shielding plate 36 is utilized. These outputs of the CCD 12 are amplified by an amplifier 21 at a gain which is (1+α) times that for the moving pictures, whereby the shortage of quantity of light due to the response delay of the light shielding plate 36 is compensated. This amplification signal is output via memories 23-25 to a mixing circuit 26, where the pixel-mixture signals are formed. Hence high-quality still pictures of optimum brightness are obtainable.

Title: Swirl-and-jet bed furnace
Inventor: UEMURA TOSHIO
IPC: F23G5/30
Filed: 1978-05-15
Abstract: PURPOSE:To improve fluidity of a fluidizing medium and even the temperature inside a furnace by increasing the diffusion angle of a perforated plate with increasing furnace diameter and directing upward the angle of small holes formed in the  plate. CONSTITUTION:When the diameter of a funnel-like perforated plate 2 is as small as about 30 cm, a diffusion angle alpha of about 90 deg. ensures good movement of a fluidizing medium. But, when the diameter of the plate 2 is increased, if the angle alpha is kept at 90 deg. the fluidized bed head pressure applies to the lower bed portion in the medium so as to adversely affect the fluidized condition. Therefore, the angle alpha is increased to reduce the difference of pressure head. Increase in furnace diameter reduces the swirling property of jet from small holes 3 formed in the plate 2. Therefore, the angle beta of the holes 3 is directed upward to prevent the reducting of the swirling property. These arramgements even the fluidized condition, stabilize the combustion, and even the temperature inside the furnace 1.

Inventor: NAGATA MASAYA
IPC: B41J2/06
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent the jetting direction of an electrically charged ink and its dropping spot on a recording medium from being disturbed by providing a static eliminating means for removing an electric charge off the print face of a recording medium between the transport means of the recording medium and a printing head. SOLUTION: A static eliminator 24 is arranged in such a manner that the static eliminator 24 comes into c tact with the print face of a recording medium, between a transport device 22 and a printing head 1. The width, i.e., the length in the X axial direction, of the static eliminator 24 is almost the same as the width of the recording medium 12. The device 24 is formed of an electroconductive member, and is grounded. Consequently, the recording medium 12 is transported by the transport device 22 and comes into contact with the static eliminator 24 before reaching the printing head 1. In this case, the device 24 is grounded, so that an electric charge on the recording medium 12 passes through the device 24 and a grounding wire and is removed, if the recording medium 12 is electrically charged.  As a result, the recording medium 12 is electrically neutralized and the jetting of an electrically charged ink is not disturbed when the recording medium 12 is transported to the surface of the printing head 1.
