Abstract: Disclosed is a cell collection device with which switching and seeing microscope images with different magnifications can be attained in one-touch without rotating a revolver. The cell collection device includes an optical system to observe cells contained in a transparent vessel under magnification. The optical system includes a first optical system to observe the cells from upper side and a second optical system to observe the cells from lower side. The first optical system and the second optical system have different magnifications, and the optical axis of the first optical system and the optical axis of the second optical system are coincident.

Abstract: A sealable vessel for cell isolation, culture and proliferation comprising a cell separation unit, comprising a cell separation membrane having fine pores capable of isolating cells; a primary culture unit, having a culture surface on which cells having passed through the cell separation membrane can be cultured and a releasing structure through which cells and a liquid held inside the primary culture unit can be freely released toward a unit having a culture surface for a subsequent step; and a main vessel unit, having a culture surface for cell proliferation on which cells that have been released from a culture unit for a preceding step can be cultured, the main vessel unit having a structure in which the cell separation unit and all of the culture unit/units for preceding step/steps can be stored.

Abstract: 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.

Abstract: During adjustment of a white balance, images having different white balances are displayed respectively on a plurality of regions on the screen 201 of the display 200, based on the red video signal Rout, the green video signal Gout and the blue video signal Bout output from the gamma correction device 30. After that, an user selects any of the plurality of regions by comparing the plurality of images having the different white balances displayed on the regions A to I on the screen 201 of the display 200 and pressing a touch panel on the screen 201. The image on the selected region is displayed on the entire screen 201 of the display 200, based on the red video signal Rout, the green video signal Gout and the blue video signal Bout output from the gamma correction device 30.

Abstract: 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%.

Abstract: 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.
