Patent JP-H07183923-A (JP)
Title: Modulator
Inventor: PIITAA EDOWAADO CHIYADOUITSUKU
IPC: H04B1/44
Filed: 1994-09-20
Abstract: PURPOSE: To suppress the deviation of output frequency (signal) to a minimum when restarting the signal on a private communication network. CONSTITUTION: A digital modulator is applied to a modulating means 1 and generates a modulated output signal from a voltage controlled oscillator 2 through a PLL system during the transmission of random modulated input signal. The input voltage component of coupling capacitor 18 corresponds to the half of total voltage swing of voltages in two data logic states. When transmission is finished and a continuous data logic state '1' or '0' is applied, however, the state of input voltage component at the coupling capacitor 18 is changed, and extremely remarkable frequency swing occurs when restarting the transmission.  Such a state can be prevented by a bias circuit having resistors 19 and 20 to perform transmission through a tristate buffer 12 for holding the input terminal of coupling capacitor at the intermediate value of total voltage swing for voltages in the data logic states '1' and '0' when performing no modulation.

Abstract: PURPOSE:To condensate light to the desired level of a quantity of luminiscence as it is stable and correct it in a short time by storing data on the quantity of luminiscence for correction prepared based on data on the quantity of luminiscence of the first storage device in the second storage device, and comparing a measured quantity of luminiscence with a desired quantity of luminiscence. CONSTITUTION:LBP consists of CPU1, D/A converters 2, 3, constant voltage circuits 4, 6, a current switching circuit 7, a laser 8, an AND circuit 9 and a D-type flipflop 10. Data on the quantity of luminiscence for correction prepared based on the data on the quantity of luminiscence of the first storage device is stored in the second storage device, and the quantity of luminiscence is again measured with the data on the quantity of luminiscence for correction while an area other than a recording medium is scanned by light. This measured quantity of luminiscence is compared with a desired quantity of luminiscence, and this data on the quantity of luminiscence for correction determines whether the data on the quantity of luminiscence of the second storage device is updated. Thus it is possible to prevent the quantity of luminiscence from being corrected improperly and also correct it finely.

Title: Method for driving liquid crystal display device with wide viewing angle
Inventor: NAKAJIMA YASUSHI
IPC: G02F1/133
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a wide viewing angle without changing the structure of a liquid crystal display device by displaying an image with synthesized viewing angle characteristics of the display having the viewing angle characteristics at a first driving voltage and the display with viewing angle characteristics at a second voltage. SOLUTION: By alternately switching a first driving voltage V1 and a second driving voltage V2 for every field, the display changes between the alignment state to give the transmittance according to the image data and the alignment state to give different viewing angle characteristics from the viewing angle characteristics by the first driving voltage V1. Therefore, the image can be displayed with synthesized viewing angle characteristics of the display having the viewing angle characteristics by the first driving voltage V1 and the display having the viewing angle characteristics by the second voltage. By this method for driving, the apparent viewing angle of the liquid crystal display device is increased by the synthesis of the viewing angle at the first driving voltage V1 applied and the viewing angle at the second driving voltage V2 applied.

Title: Plate-type cathode-ray tube
Inventor: KAWACHI YOSHIKAZU
IPC: H01J31/12
Filed: 1983-12-26
Abstract: PURPOSE:To equalize the beam transmittance for each scanning line which is influenced by the crosspiece of the slit so as to prevent any luminance nonuniformity of the image by causing an electron beam to bump against the crosspiece of only one of slit-like electrodes installed facing each other. CONSTITUTION:The pitch of the crosspieces of a slit-like electrode 31a, that of a slit-like electrode 32a and that of a slit-like electrode 33a are 4 (the number of electrodes +1)X width of the field scanning line. The shift between crosspieces 31b and 32b, that between crosspieces 32b and 33b and that between crosspieces 33b and 31c equal the width of the field scanning line. An electron beam 30a becoming incident upon the first electrode 31a at an angle of theta passes through the electrode 31a without bumping against the crosspiece of the slit before bumping against the crosspiece 32b of the second electrode 32a, and does not bump against the crosspiece of the third electrode 33a. Owing to the above constitution in which none of the crosspieces of the electrodes 31a, 32a and 33a face each other and which is characterized by an electron beam bumping against the crosspiece of only one electrode during passing through the electrode group, a homogeneous beam transmittance is achieved and any luminance nonuniformity can be prevented.

Title: Method for supplying illuminating light in electronic endoscope device
Inventor: CHIKAMA TOSHIO
IPC: H04N7/18
Filed: 1985-11-11
Abstract: PURPOSE:To make images distinct, to prevent flicker on a screen and to improve the image quality and the color reproducibility by supplying an illuminating light pulse interruptedly to control driving of a motor so that the phase difference is equal to a set phase difference. CONSTITUTION:A chopper 26 is rotated once at each one frame scanning time, and the illuminating light is not supplied into a somatic cavity when a shielding part 26b of the chopper 26 intercepts a luminous flux A of the illuminating light, and the illuminating light is supplied there only when a window 26a is in the position of the luminous flux A, and a still image is made distict by supplying the illuminating light interruptedly. A comparator 43 compares a set speed signal Ssd and a detected speed signal Ss with each other and outputs the difference signal to a motor driving circuit 44. The motor driving circuit 44 increases or reduced the power supplied to a motor 25 based on the difference signal to control the rotative speed of the shopper 26. Since the set phase difference is so determined that the time when the center part of the window part 26a passes the center part of the luminous flux A coincides with the transfer time of a picture signal to be used for odd field scanning, the middle of the supply time of the illuminating light pulse coincides with the transfer time of the picture signal.

The leakage of the rotor cooling air R is partly diverted after some of the labyrinth seals in the exhaust gas casing 14 and is used as shielding air. Ambient air is introduced as cooling air K into a bearing space 16 wherein it is uniformly distributed about via the gland bushing 18.
