Title: Trunk line dial-in receiver
Inventor: TAKEDA YOSHINORI
IPC: H04Q3/58
Filed: 1986-09-19
Abstract: PURPOSE:To easily add dial-in function to a private branch exchange having no dial-in function by converting a number information transmitted from the trunk line to such a number information corresponding to the number of an extension telephone set of the private branch exchange, and providing a means to call by direct calling. CONSTITUTION:If an incoming call arrives at a trunk line dial-in receiver EQU from the trunk line, a trunk line incoming call circuit ICDECT in the trunk line dial-in receiver EQU transmits a detection signal to a trunk line dial-in receiver control part EQUCPU. The trunk line dial-in receiver control part EQUCPU collates the number information transmitted from the trunk line with the number plan of the private branch exchange stored in a trunk line dial-in receiver main memory part EQUMEN, when they agree with each other, transmits the number information to a pulse sender SND. The trunk TRK, after receiving a dial pulse, transmits the number information to a central processing unit CPU, and the CPU executes a well known connection to call an extension telephone set EXT-A.

Abstract: PURPOSE:To allow the precise focusing to a subject moving at a high speed by previously measuring the distances to the plural positions in the predicted moving route of the dynamic subject and the relative angle of a camera with these positions based on the signal from a signal source and previously storing the data. CONSTITUTION:The distances up to the respective plural prescribed positions A to D in the moving route L predicted with respect to the subject P moving in the specific route are previously measured by the camera 11.

The information thereon is previously stored in the camera. The reception pulses for distance measurement from the signal source 13 are received in the sensors 12a, 12b at the time of actual photographing. The relative angle of the camera 11 and the signal source 13 is indexed and the distance up to an arbitrary pass route is calculated by a control circuit from the previously stored distances and angles and the focusing lens is automatically moved at a high speed to the focal position. The focusing to the dynamic subject is precisely executed in this way.

Abstract: PROBLEM TO BE SOLVED: To enhance printing quality without increasing the light emitting number of times of LED elements per one pixel. SOLUTION: In an image forming apparatus wherein a large number of LED elements arranged on a line are divided into a plurality of blocks and a time is shifted at every block to control the lighting of the LED elements according to image data to emit light a plurality of times per one pixel, the electrostatic latent image formed on a photosensitive member is shifted in a sub-scanning direction at every block of the LED elements by the relative movement of the photosensitive member and the LED elements while the shift quantity (y) thereof is reduced by emitting light from the LED elements a plurality of times. A plurality of light emitting times per one pixel of the LED elements are also set to two kinds of different times and, for example, the first and final light emitting times of the LED elements per one pixel are made shorter than other light emitting times.  By this constitution, the shift quantity (y) of the electrostatic latent image in the sub-scanning direction is sharply reduced without increasing the light emitting number of times from the LED elements per one pixel.

Title: Liquid crystal driving circuit
Inventor: MOTOHASHI TOSHIHARU
IPC: H04N5/66
Filed: 1991-09-03
Abstract: PURPOSE:To prevent the DC offset of a driving signal to a liquid crystal panel from being generated. CONSTITUTION:The liquid crystal driving circuit consists of a brightness adjusting circuit 14 for an input video signal (a), a multiplex driver 18 which generates the inverted signal of the brightness-adjusted video signal (b) and puts this inverted signal and uninverted signal together to generate a symmetrical driving signal, and the liquid crystal panel 22. The DC level of the video signal (a) inputted to a DC clip means and a variable slice circuit provided to the brightness adjusting circuit 14 is adjusted to adjust the brightness level of the input video signal (a). Consequently, the inverted signal and uninverted signal have peaks symmetrically about the intermediate potential of a voltage for liquid crystal driving, so the waveform of the uninverted signal is not distorted as a result of the black level adjustment of the liquid crystal panel. Therefore, the DC offset is never generated as a result of the black level adjustment.
