Abstract: Apparatus for rapidly transferring data between a central processing unit (CPU) of microcomputer apparatus and floppy disc drives, includes a floppy disc controller for interfacing the floppy disc drives with the CPU and generating an interrupt request status signal indicating whether a command has been executed and a data request status signal indicating whether data is to transferred between the floppy disc controller and the CPU, the CPU generating command signals in response to these status signals; a data bus connecting the CPU to data access lines of the floppy disc controller; a bidirectional buffer interposed between the data bus and the data access lines for gating the data between the floppy disc controller and the CPU through the data bus and for gating the interrupt request status signal and data request status signal through the data bus to the CPU in response to gating signals; first and second gate circuits for gating the status signals to the buffer in response to the gating signals; a NOR gate for supplying gating signals to enable the buffer in response to the command signals; and an OR gate for supplying gating signals to enable the first and second gate circuits in response to the command signals, whereby rapid data transfer is achieved without using a direct memory access controller.

Abstract: Radio receiving apparatus for receiving signals in plural frequency bands. Plural signal processing channels are provided, each channel being associated with a respective frequency band and each being tunable to different frequencies within its associated band to derive information signals when tuned to broadcast frequencies. Depending upon which of the signal processing channels is tuned to a broadcast frequency, a controllable switch connects that channel to an output circuit so as to supply the derived information signals thereto. A pulse generator generates intermittent pulse signals when the tuning condition of at least one of the signal processing channels is changed. These pulse signals are used to sample the tuning condition of that signal processing channel to determine if that channel is tuned to a broadcast frequency. A switch control circuit controls the switch to connect to the output circuit the particular signal processing channel which is tuned to a broadcast frequency.

Abstract: PROBLEM TO BE SOLVED: To achieve stable focus servo control in an optical recording system using a pulse laser beam as a laser beam for recording.SOLUTION: A pulse laser beam for recording is irradiated, and separately from this, a first CW laser whose optical axis is inclined is irradiated for focus servo control. Since the optical axis of the first CW laser beam is inclined with respect to the pulse laser beam at this time, only reflected light of the first CW laser beam can selectively be received. This can effectively suppress influence given by the pulse laser beam during focus servo control, and consequently, focus servo control during recording can be performed in a stabler manner in an optical recording system using a pulse laser beam for a recording laser beam.

解决方案：照射用于记录的脉冲激光束，并且与此分开地照射光轴倾斜的第一CW激光用于聚焦伺服控制。 由于此时第一CW激光束的光轴相对于脉冲激光束倾斜，所以只能选择性地接收第一CW激光束的反射光。 这可以有效地抑制在聚焦伺服控制期间由脉冲激光束产生的影响，因此，可以在使用用于记录激光束的脉冲激光束的光学记录系统中以更稳定的方式执行记录期间的聚焦伺服控制。 版权所有（C）2013，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a biometrics authentication system having a small and simple configuration and implementing both of biometrics authentication and position detection. SOLUTION: The biometrics authentication system 1 includes a near-infrared light source 10, a cover glass 11, a microlens array 12, a light-receiving element 13, an image processing section 14, an authentication section 15, a position detection section 16, a light source driving section 181, a light-receiving element driving section 182 and a control section 19. When a living body 2 on the upper part of the cover glass is irradiated with light from the near-infrared light source 10, the light with which the living body 2 is irradiated is condensed by the microlens array 12, and then is sensed by the light-receiving element 13. Consequently, light-sensing data of the living body 2 is obtained. The image processing section 14 generates disparity image data, on the basis of the light-sensing data. The authentication section 15 performs biometrics authentication, on the basis of the disparity image data. The position detection section 16 performs position detection. The biometrics authentication and the position detection are performed by the same light source and detection optical system. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an imaging apparatus for increasing the number of image receiving areas of an imaged pixel.
SOLUTION: The imaging apparatus includes: an imaging lens section 11 having an aperture diaphragm 10; a microlens array 12 composed of a plurality of microlenses two-dimensionally arranged; an image sensor 13 producing imaging data, based on received light; and an image processing section 14 for applying predetermined image processing to the imaging data obtained from the image sensor 13.

Abstract: PROBLEM TO BE SOLVED: To provide an image pickup device capable of switching image pickup modes.
SOLUTION: A relative distance between a micro lens array 12 and an imaging device 13 is changed depending on whether heat is supplied from heat supply parts 19A and 19B to bi-metallic strips 18A and 18B. When the heat is supplied, the micro lens array 12 is displaced to the opposite side with respect to the imaging device 13 along an optical axial direction, so that an incident light from an image pickup lens 11 is refracted in the micro lens array 12 and is converged on the imaging device 13. When the heat is not supplied, the micro lens array 12 and the imaging device 13 stay approximate to each other, so that the incident light is not refracted but reaches the imaging device 13 as it is. Image pickup modes can be switched between an image pickup mode for applying prescribed image processing to image pickup data obtained by converging the light on the imaging device 13 and an image pickup mode for obtaining the image pickup data by having the incident light reach the imaging device 13 as it is.
