Title: Time base correction device
Inventor: MASUI HIKARI
IPC: H04N9/89
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a time base correction device which extracts the synchronizing signal component from the digital video signals and secures the phase synchronization of the video signal via an arithmetic synthesis by using the horizontal synchronizing signal of the video signals to perform the signal write control and using a synchronizing signal generation circuit to perform the signal read control. SOLUTION: A comparator 112 compares the video signal data with the output data of a constant generation circuit 111 to simply separate a synchronizing signal. Based on this synchronizing signal, a timing generation circuit 113 generates an H pulse to control a 1st address generation circuit 115 which performs the address control of a memory 114, a blanking pulse to control a gate circuit 102 and a V pulse to control a synchronizing signal generation circuit 117 respectively. The initialization is secured by a vertical synchronizing signal (V pulse) which is separated from the video signal outputted from the circuit 113. Thus, the time discontinuity that is caused after the time base correction can be corrected in every vertical cycle.

IPC: G03G15/20
Filed: 1992-08-28
Abstract: PURPOSE:To hold the fixing temperature of a fixing roller when the input voltage of an electronic copying machine is dropped. CONSTITUTION:Plural (two in this embodiment) heating lamps 621 and 622 disposed inside the fixing roller 62 are set within the capacity (1.5kVA) of the copying machine.

Title: Liquid crystal shutter
Inventor: FUJIMURA HIROSHI
IPC: G02F1/1335
Filed: 1987-09-14
Abstract: PURPOSE:To reduce a light leak in an electric field nonapplication part and a shutter part which is turned off by orienting liquid crystal molecules so that they rise slantingly almost at right angles to the surface of a substrate. CONSTITUTION:When a low frequency electric field is applied between common electrodes 13a and 13b and a segment electrode 15, the liquid crystal molecules (a) which are oriented rising slantingly almost at right angles to the surfaces of substrates 11 and 12 further rise because the dielectric anisotropy of the liquid crystal molecules (a) is positive to enter a homeotropic orientation state, and shutter parts Sa and Sb are turned off so that light is not transmitted. When a high frequency electric field is applied, they fall to enter a homogeneous orientation state because the dielectric anisotropy of the liquid crystal molecules (a) is negative and then the liquid crystal molecules enter a bright state showing nearly flat spectral characteristics almost at a specific tilt angle, so an application time is so set as to cut off the application of the high frequency electric field at this time, thereby using the period as a shutter OFF state. Thus, the shutter parts Sa and Sb are turned on and off to control the transmission of light and the light leak in the electric field nonapplication part and the shutter part which is turned off is reduced.

Title: Picture shading method and picture processor
Inventor: SUZUKI KATSUNORI
IPC: G06T15/80
Filed: 1991-09-10
Abstract: PURPOSE:To prevent the excess shading processing. CONSTITUTION:The Gouraud shading processing is performed in the case the size on the triangle display screen for picture shading processing is smaller than Kp (22). In the case the size of the triangle is bigger than the Kp (22 to 25), the triangle is divided into sub triangles by the number of divisions according to the size, and the luminance of each summit of each sub triangle is obtained by the normal vector of each summit of each sub triangle obtaining the normal vector of each summit of the divided each triangle by the one- dimensional interpolation. With the obtained luminance of each summit of each sub-triangle, the shading processing is performed for each sub-triangle. Accordingly, the visually excess processing can be prevented by limiting the unit area of the Gouraud shading processing to the size which can be recognized on the display.

Filed: 1990-09-03
Abstract: PURPOSE:To generate a pulse of a prescribed period and a prescribed width by applying 1/2 frequency division to pulses of two kinds of periods generated by changeover of two kinds of different charge discharge time constants alternately. CONSTITUTION:The generator is provided with a pulse generating circuit 200 comparing a voltage change caused through charge/discharge of a capacitor 5 with a threshold level to generate a pulse and control circuits 13,14,20 selecting alternately two kinds of different charge/discharge time constants every time a pulse is generated from the circuit 200. Moreover, the generator is provided with a frequency divider circuit 20 applying 1/2 frequency division to a pulse generated from the circuit 200 to generate a pulse of a prescribed period. That is, since the two kinds of the charge/discharge time constants are respectively constant regardless of the dispersion in the threshold level at all times, a peak of an output pulse is generated by applying 1/2 frequency division to a 1st pulse and a bottom of the output pulse is generated by applying 1/2 frequency division to a 2nd pulse, then the pulse width and the period of the output pulse are always constant. Thus, the pulse generator whose pulse width and generating period are constant is realized.

Title: Digital interface circuit
Inventor: KANAIDA SHINJI
IPC: H04L7/02
Filed: 1989-09-06
Abstract: PURPOSE:To synchronize a data and a clock signal by deviating a phase of the clock signal when the coincidence between a transition period of the digital data and a pulse edge of the clock signal is detected. CONSTITUTION:When a clock signal is inputted to a clock signal input terminal 6, the clock signal is branched into two, the one is inverted for its level at an inverter 7a and the phase is changed by 180 deg.. Moreover, the other is delayed at a buffer 7b by a delay time of the inverter 7a and formed into a noninverting clock having a just 180 deg. of phase difference from that of the inverted clock outputted from the inverter 7a. Thus, the data fetch timing represented by the clock signal is deviated from the transition period of the digital data. Thus, the state capable of fetching the digital data in the timing in compliance with the clock signal, that is, the synchronization state is attained.
