Title: Digital image forming device
Inventor: NOGUCHI KOICHI
IPC: G03G15/08
Filed: 1991-02-18
Abstract: PURPOSE:To achieve long service life by reducing the driving time of a two- component developing means by controlling the drive of the two-component developing means according to the output signal of an image presence/absence means. CONSTITUTION:An electrostatic latent image is formed by writing image data on a photosensitive body. The electrostatic latent image is developed by the two-component developing means. Here, the presence/absence of an image to be developed by the two-component developing means is detected by the image presence/absence detecting means 1, and a drive control means 2 controls the drive of the two-component developing means according to the output signal of the image presence/absence detecting means 1. Subsequently, for example, the control means generates a toner replenishment signal, and a toner replenishment part driving means drives a toner replenishment part based on the toner replenishment signal. Then, a driving means is started in response to the toner replenishment signal to drive the two-component developing means; it drives the two-component developing means until the prescribed length of time elapses after the stop of toner replenishment.

Title: Surface emitting type light-emitting diode
Inventor: YAMAUCHI NORIKATSU
IPC: H01L33/10
Filed: 1991-02-19
Abstract: PURPOSE:To enhance an element lifetime by reducing lattice defects within an active layer in a surface emitting light-emitting diode having a light reflection layer of a multi-layer structure and make it possible to emit the light at comparatively small operation voltage. CONSTITUTION:A composition of an interface portion of each layer of a light reflection layer formed with a multi-layer structure is continuously made to change as shown in a solid line of Fig.2. Since a lattice mismatching within the light reflection layer is mitigated to restrain a generation of crytical defects, the crytical defects within an active layer formed on the light reflection layer are also reduced and a dark line deterioration due to a dislocation growth at operating is restrained to lengthen an element lifetime. Further, since discontinuity of bands within the light reflection layer is mitigated, an electric resistance is lowered, whereby this embodiment can be operated at a small operation voltage.

Title: Video amplifying circuit
Inventor: TACHIBANA KENICHI
IPC: H04N5/20
Filed: 1981-03-31
Abstract: PURPOSE:To obtain a picture having the optimum black and white gradations, by controlling the fall or the rise of the DC level that decides the luminance level of a luminance signal according to the presence or absence of a black signal and at the same time controlling the amplitude of the luminance signal. CONSTITUTION:The luminance signal supplied through a terminal 1 is fed to a DC reproducing circuit 3 via an amplifying circuit 2, and the DC component is reproduced to fix the black level. Furthermore the signal near the black level is detected by a black level detecting circui 4 and in the form of a black signal. This output of detection sets up and down the DC level of the luminance signal of the circuit 3 via a black level control circuit 5 and performs an automatic compensation for the fixed black level. At the same time, the black level is fed back to the circuit 2 via a luminance amplitude control circuit 11 that increases and decreases the amplitude of the luminance signal when the black level is detected by the circuit 4. Thus the white peak level is controlled to an optimum value by adding a feedback circuit to a conventional black level compensating circuit and in accodance with the change of the black level. As a result, a white or black picture is obtained with the good balance of gradation.

Title: Method for driving liquid crystal display device
Inventor: OKAZAKI NETSUO
IPC: G02F1/133
Filed: 1990-02-26
Abstract: PURPOSE:To make the contrast on a display screen constant by applying a voltage and scanning a scanning electrode group sequentially while a scanning starting electrode in the scanning electrode group is shifted by a specific number of scanning electrodes at every prescribed frame. CONSTITUTION:A scanning starting signal is generated at the outputs of 5-1, 5-2,..., 5-n, at every frame. Then pulses are outputted sequentially from a flip- flop for which the scanning start signal is inputted. Further, a selection period in each frame shift in position is moved at every frame in its position. Assuming that X is a voltage applied to a signal electrode, Y1-X and Yn-X are voltages applied to liquid crystal layers on a 1st scanning line and an (n)th scanning line and both terminals of an MIM element. At this time, the voltage waveforms of the Y1-X and Yn-X are different in phase and polarity, but conform with each other in (n)-frame units. Consequently, the contrast on the whole screen becomes constant.
