Title: Focal point detecting device for single-lens reflex camera
Inventor: SEKIDA MAKOTO
IPC: G02B7/38
Filed: 1987-12-29
Abstract: PURPOSE:To detect a focal point without scaling up a device by extracting a high frequency component from a photographing luminous flux and detecting the focal point from the high frequency component. CONSTITUTION:The photographing luminous flux from an object passes by a photographing lens 1, comes to a movable mirror 2, passes through a semi-transmitting plane 3 provided on the movable mirror 2, makes incident on an auxiliary mirror 4, is reflected therein, and is subjected to primary image formation on a primary image formation equivalent plane 5'. An image reforming lens 7 is provided behind the primary image formation plane 5', and reforms an image of the photographing luminous flux on a photoelectric conversion element 8 by the power of image reforming lens 7. The image reforming lens 7 receives a certain vibration by a vibrating device 6 made of piezoelectric elements, and slightly moves the image forming plane back and forth. The photographing luminous flux incident on the photoelectric conversion element 8 is outputted as an image signal, from which specific high frequency components are extracted. The signal intensities of said components are compared with each other by a circuit arranged in a subsequent stage, and a focused state is detected. Thus, a focal point can be detected without scaling up the device.

Title: Optical disk apparatus
Inventor: MASHITA TSUGUAKI
IPC: G11B7/005
Filed: 1990-11-30
Abstract: PURPOSE:To change regenerating conditions and to enhance the probability for reproducing data by regenerating the data of an optical disk based on reflected light of a light beam which is projected on the optical disk, and performing reproduction again when the regeneration fails. CONSTITUTION:An optical beam LB which is emitted from an optical head 1 accesses the recording region of a track from which data are to be regenerated. The reflected light from the recording region is received with the optical head 1. An output signal SO associated with the amount of the received light is inputted into an attenuated-amount changing circuit 5. An output signal SA of the circuit 5 is inputted into an address-signal detecting circuit 6, and the signal SA associated with the address is detected. When an output signal SAO from an address-signal-discontinuity detecting circuit 9 is not inputted into a control part 8, the data of an optical disk 2 are reproduced based on the regenerating signal SR which is outputted form the attenuation-amount changing circuit 5 in correspondence with the detected address signal SA. When the regeneration fails, reproduction of the data whose reproduction fails is retried based on the command from a host computer. Thus, the probability of success in data regeneration can be enhanced.

Title: Printing control system for laser printer
Inventor: SETO FUMIAKI
IPC: G06K15/12
Filed: 1989-12-26
Abstract: PURPOSE:To continue printing even when the cycle of a start pulse is made abnormal by instantaneous interruption by turning OFF the beam-on signal of a beam-on circuit and inhibiting the read of a read circuit when a start pulse check circuit detects the abnormality of the cycle. CONSTITUTION:Since the beam-on signal of a beam-on circuit 4 is turned OFF when a start pulse check circuit 5 detects the abnormality in the cycle of the start pulse, one line is not drawn to an object to be scanned and a blank line for one scan is generated. However, the blank line can be ignored with the increase of resolution. The read of a read circuit 6 is inhibited and a video signal is not outputted by the scan. Therefore, although the blank line for one scan is generated, there is no trouble even when printing is continued, and printing can be prevented from being stopped. Thus, even when a laser light source 1 is temporarily instantaneously interrupted, printing can be continued and printing speed and printing efficiency can be improved.

A discharge volume of the first ink drop can be smaller than that of the second-fourth ink drops, and therefore a pixel by the first ink drop is made smaller than a pixel, for example, solely by the second ink drop. Even the largest fourth pixel can be formed to be approximately equal in size to that obtained when the signal of (B) is used. A graininess at a highlighted part is suppressed and an image of a high density is obtained at a high density part.
