20090176333 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - To prevent semiconductor chips from adhering to the trays during transport, a method is employed which transports semiconductor chips in the following state. When trays provided with a plurality of accommodating portions having a recessed cross section for accommodating semiconductor chips on a main surface thereof are stacked in a plurality of stages, the semiconductor chips are accommodated in spaces defined by the accommodating portions formed over the main surface of the lower-stage tray and corresponding accommodating portions formed over the back surface of the upper-stage tray. Here, on bottom surfaces of the accommodating portions formed over the back surface of the upper-stage tray, isolated projections having a height which prevents the projections from coming into contact with the semiconductor chips are arranged in a scattered manner. In this way, it is possible to prevent the semiconductor chips from adhering to the back surface of the upper-stage tray. | 07-09-2009 |

20090015179 | BACKLIGHT CONTROL DEVICE AND DISPLAY APPARATUS - A PWM generation circuit is set so as to generate a PWM pulse signal having a frequency that is an odd number times a vertical synchronization frequency. A frequency division circuit frequency-divides the PWM pulse signal generated by the PWM generation circuit. An AND gate calculates the logical product of the PWM pulse signal generated by the PWM generation circuit and a frequency-division pulse signal outputted from the frequency division circuit. An OR gate calculates the logical sum of the PWM pulse signal generated by the PWM generation circuit and the frequency-division pulse signal outputted from the frequency division circuit. A selector outputs an output signal of the OR gate as a dimming pulse signal in a case where the set duty ratio is not less than 50%, while outputting an output signal of the AND gate as a dimming pulse signal in a case where the set duty ratio is less than 50%. Consequently, the frequency of the dimming pulse signal is five-second the frequency of a vertical synchronizing signal. | 01-15-2009 |
20090243994 | BACKLIGHT CONTROL DEVICE AND DISPLAY APPARATUS - A PWM generation circuit generates a PWM pulse signal having a variable duty ratio in order to control the luminance of a backlight. An edge detection circuit outputs a leading edge signal in response to the rise of the PWM pulse signal generated by the PWM generation circuit. A set value pulse generation circuit generates a set width pulse signal in response to the rise of the leading edge signal. The pulse width of the set width pulse signal is set so as to be larger than the minimum PWM pulse width. An OR gate calculates the logical sum of the set width pulse signal and the PWM pulse signal. An inverter circuit feeds a driving signal to a backlight on the basis of an output signal of the OR gate. | 10-01-2009 |
20100171776 | PICTURE DISPLAY DEVICE - A picture display device including a picture display section for projecting an input picture signal; a light source for visualizing a picture in the picture display section; a moving picture detecting section for outputting a scanning line movement determination signal for every scanning line based on a movement amount of a picture signal for every scanning line; a PWM pulse generating section for controlling flashing of the light source; and a PWM control section for outputting a moving image specifying signal that specifies a moving image area included in a frame based on the scanning line movement determination signal to control the PWM pulse generating section. The PWM control section controls the PWM pulse generating section in a blinking mode by turning off the light source in a period for scanning the moving image area including a scanning line having a largest movement amount. | 07-08-2010 |
