Title: Optical information recording apparatus
Inventor: WATABE AKIYASU
IPC: G11B7/125
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain an optical information recording apparatus in which peak power, erase power and bottom power are controlled precisely even when a quantity-of-radiant-light detector with a limited detecting region is used in the recording apparatus for information with reference to a phase change-type medium and by which the information can be recorded in such a way that a recording mark is not lost. SOLUTION: On the basis of an applied current on which every erase level current changed over by a current driving device 9 for an erase level is superposed, a CPU 1 detects the luminous power of every laser beam when a semiconductor laser light source (LD) 2 emits light. Then, on the basis of the luminous power and on the basis of the applied current which generates the luminous power, the differential efficiency of the LD 2 is calculated, and a bottom-level current and a peak-level current in a recording operation are decided on the basis of the differential efficiency.

Filed: 1987-08-21
Abstract: PURPOSE:To accurately and easily judge the presence of a whistle, by comparing the timewise changing sound pressure level of a received acoustic signal with two preset high and low threshold value levels. CONSTITUTION:The acoustic signal of the frequency band of the whistle sound emitted from a ship is received by a filter means 5 consisting of highly directional microphones 1a-1d and a BPF and the timewise change of the sound pressure level of the acoustic signal received by a detection means 6 is led out and the led-out sound pressure level of the acoustic signal is compared with two preset high and low threshold value levels by a microcomputer (MC) 8 as a discrimination means. Then, the presence of whistle sound is identified during a period when the sound pressure level of the acoustic signal exceeds the high threshold value level and subsequently reaches the low threshold value level and the absence thereof is identified during a period when said sound pressure level falls below the low threshold value level and subsequently reaches the high threshold value level. The MC 8 leads out the pattern of the whistle sound from the discrimination result of the presence and absence of the whistle sound to discriminate the same.

Filed: 1988-08-23
Abstract: PURPOSE:To prevent ink from mixing when ink is replaced by providing an ink quantity regulating member separately from the bottom plate of an ink cover, and linearly moving it in parallel with its surface to open or close an ink passage. CONSTITUTION:A blade driving pneumatic cylinder 34 is attached to the rearward vertical face 13a of an ink fountain base 13. When a valve 35 is switched to its open state, a blade 26 pushes rearward a push rod 36 by the elastic force of a spring 27 to be stopped at a rear end position. When the blade 26 is moved to its open position, an ink passage 33 is opened to form a gap between an ink original roller 12 and the end of the blade 26. When the valve 35 is switched to a closed state so that the rod 36 is advanced to the front end position, the blade 26 is advanced to the front end position to close the passage 33. Accordingly, the blade 26 is moved linearly in a direction parallel to the surface to open or close the passage 33. Therefore, it can prevent previous ink from mixing with the ink when the ink is replaced without step.
