Title: Focus controller
Inventor: YAMAGUCHI HIROYUKI
IPC: G11B7/095
Filed: 1983-06-14
Abstract: PURPOSE:To increase the gain of a focus control system to the low band component of a DC disturbance which is due to a shift of a disk produced by its attachment, the warp of the disk, etc. and applied to the focus control system, by incorporating an integrator to the focus control system. CONSTITUTION:The light beam of a light source 1 is focused and irradiated to a disk 7 which is capable of optical record and reproduction. The focusing state of the light beam on the disk 7 is detected by the output of a differential amplifier 11, and a driving circuit 14 is driven so that the light beam has a fixed focusing state on the disk 7 in response to the detection output of the amplifier 11. The output of the amplifier 11 is supplied to an integration circuit 25 after passing through a phase compensating circuit 12. The circuit 25 is provided with an operational amplifier 26 having sufficiently large input impedance and gain, resistances 27 and 28, and a capacitor 29. Thus the low band gain of a focus control system is increased with reduction of a focus control error.

Filed: 1994-05-20
Abstract: PURPOSE:To surely prevent improper use of a used cartridge by taking up a transfer material by rotating a paper winding shaft at taking up the transfer material when a detecting means detects a terminal end of the transfer material and taking the entire material from an extension shaft so as to house it into the cartridge. CONSTITUTION:In forming images, a paper P is conveyed along a conveying passage 1 and stopped at a position opposite to a thermal printer head 2 on a platen roller 9. At every transfer by an ink ribbon 3 on the paper P, the ribbon is taken up by a paper winding shaft 4 by predetermined quantities. In this case, when the ink ribbon 3 at an extension shaft 5 comes to an end, the rotational speed of the extension shaft 5 rises and an interval of waveforms to be outputted from an encoder becomes shorter. Then, an output signal of the encoder and a reference signal are compared at a CPU. When an end is determined, the extension shaft 5 is rotated so as to take up the ink ribbon 3 entirely by the paper winding shaft 4, and the ink ribbon 3 is entirely housed in a cartridge.

Abstract: PURPOSE:To detect the knocking accurately by extracting a specified frequency component from an electric signal corresponding to the vibration of an internal combustion engine, judging the knocking by the ratio of two consecutive sampled values at every specified time interval, thereby facilitating the determination of a threshold value. CONSTITUTION:The vibration of the internal combustion engine is converted into the electric signal by an electric signal converter part 1. The specified frequency component, whose variation becomes large at the knocking part within said electric signal, is extracted in a specified frequency extracting part 2. Sampling is performed in a sampling part 3 at every specified time interval. The ratio computation of the two consecutive sampled values from the sampling part 3 is performed in a ratio value computing part 4. The knocking is judged by a knocking detecting part 5 based on whether this ratio exceeds the thrshold value or not. In this constitution, the threshold value in the detecting part 5 is determined readily and positively regardless of the effect such as the signal level variation due to the causes other than the knocking. Therefore the accurate knocking detection can be performed.
