Title: Circuit for processing magnetic recording and reproducing signal and recording and reproducing device using the same
Inventor: SATO NAOKI
IPC: G11B20/10
Filed: 1992-06-09
Abstract: PURPOSE:To provide a small-sized and high performance magnetic recording and reproducing device without applying an AGC circuit by directly degitize a regenerative signal from a magnetic head through a simple LPE with an A/D converter. CONSTITUTION:The magnetic head 2 is selected and arrived at an objective magnetic disk 1. The regenerative signal from the head 2 passes through a preamplifier 3 and an LPF 5 and converted to a digital signal at the A/D converter 7. A digital equalizer 8 executes waveform-equalization including the characteristics of a waveform processing and identifies and reproduces information recorded in a Viterbi decoder 9 of a poststage. At this time, an equalization error calculation circuit 11 subtracts identified result from an equalized output value and outputs the equalization error (e). The reference electric potential V is controlled to be fed back negatively so that the equalization output value is a proper value for identification at the time of degitizing an analog signal X by a gain control signal generator circuit 14 operating with the equalization error 9 (e) and the output Z of an identifying equipment 9. A VOC 13 outputs a CLK so that the equalization error (e) is reduced by a VOC control circuit 12 operated by the signal (e) and the result Z.

IPC: G04G99/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide an electronic-controlled mechanical clock capable of reducing the metering fluctuation. SOLUTION: An electronic-controlled mechanical clock is provided with a generator 2 to convert the mechanical energy to be transmitted through a train wheel from a main spring to the electric energy, and a rotation controlling means 10 to control the period of rotation of the generator 2. The rotation controlling means 10 effects the first brake control to apply a brake to the generator by the pre-set time at a specified timing when the value of an up- down counter 60 in which the rotation detection signal FG1 corresponding to the period of rotation of the generator 2 and the reference signal fs from a time standard source are inputted reaches the first set value, and the period of rotation of the generator 2 is faster than the reference signal period. Thus, the increase of the operational speed of the generator 2 can be suppressed, and the metering fluctuation can be reduced.

Filed: 1995-05-24
Abstract: PURPOSE: To easily secure the directivity approximate to the logical calculated value and also to facilitate the production of a composite vibrator by arraying plural vibrators with their radiation surfaces set approximately at the same level and with spaces secured among them and then joining together the vibrators by means of an elastic adhesive. CONSTITUTION: A composite vibrator 1 consists of plural small vibrators 3 which are made of a PZT (piezoelectric) material, etc., in round shapes and arrayed with their radiation surfaces set approximately at the same level and with prescribed spaces e1 secured among them. These spaces of vibrators 3 are filled with an elastic rubber adhesive 5, so that the vibrators 3 are joined together in a single body. The adhesive 5 also forms a coat layer that covers the outer circumference side of the vibrator 1 in thickness e2 . As the adhesive 5 flexibly deforms, the vibrators 3 can vibrate freely and almost independently of each other with no mutual influences of their distortions. Thus the directivity that is approximate to the logical calculated value can be secured.

Title: Picture reading device
Inventor: KIMURA FUJINORI
IPC: H04N1/04
Filed: 1983-08-17
Abstract: PURPOSE:To read light intensity on a straight line perpendicular to the direction of scanning moving a carrier continuously and to enable high speed reading by slanting the direction of arrangement of photodetectors to a straight line perpendicular to the direction of movement of the carrier. CONSTITUTION:Light intensity of areas divided finely in the direction perpendicular to the direction of scanning is read by photodetectors (a)-(p) in the process of moving the carrier continuously from left to right. The carrier moves dis tance (l) while signals from the photodetectors (a)-(p) are processed. As the direction of arrangement of the photodetectors (a)-(p) is slanted to a straight line 4 at an angle of theta, when the signal of the first photodetector (a) is being processed, the last photodetector (p) is delayed for 1 dot of the size (l) to the direction of scanning. However, when the signal of the photodetector (p) is processed, the carrier advances and a signal that read the light intensity at a position where the delay for 1 dot is regained is outputted.
