Title: Detector for tension arm position of tape reader
Inventor: MIZUNO YUTAKA
IPC: G06K7/01
Filed: 1983-08-05
Abstract: PURPOSE:To detect economically the absolute position of a tension arm by using an initial position setting means which cancels the clearing state of an up/down counter and a means which reads the contents of the up/down counter. CONSTITUTION:A microcomputer 31 clears the contents of up/down counters 29 and 30 if they are under initial resetting when a power supply is applied. Then a roll-out reel motor 2 and a take-up reel motor 19 are revolved in the negative and positive directions when it is decided that the 1-revolution signals of incremental rotary encoders 25 and 26 are turned off. Then the clear states of the counters 29 and 30 are cancelled. Thus the counters 29 and 30 perform the up/ down counts in response to the shifts of tension arms 5 and 16. These count values show the absolute positions of arms 5 and 16 respectively. Therefore the position of the tension arm is obtained by reading the count values of counters 29 and 30 by the computer 31.

Title: Avalanche photo diode
Inventor: ITOU MASANORI
IPC: H01L29/864
Filed: 1977-12-01
Abstract: PURPOSE:To make possible low noise operation of a wide wavelength region by selectively removing part of N layer to expose P layer and letting long wavelength light enter the N layer remained on the surface and short wavelength light the exposed P layer respectively. CONSTITUTION:The N layer of the portion of a region 5 is removed to expose P layer. The long wavelength light having entered the region which has the N layer on the surface arrives at the P layer while being hardly absorbed in the N layer and itturns out that injection of electrons is accomplished there. In this case, the hole injection in the N layer is small and therefore the production of noise is kept low. On the other hand, the short wavelength light is radiated to the region 5 and electrons are injected near the surface thereof to allow avalanche current to be produced and therefore no adverse influence is given by the hole injection.

IPC: B41J15/16
Filed: 1990-06-04
Abstract: PURPOSE:To hold the difference between the carrying force through a carrier means and the braking force through a braking means almost constant by detecting the winding diameter of a recording medium through a detecting means to change the carrying force of a carrying force-imparting means. CONSTITUTION:In the vicinity of a roll-shaped recording medium RP, a detector 18 for detecting the winding diameter of the medium is provided and the arm 18c of the detector 18 rotates clockwise as the diameter of the recording medium RP becomes smaller so that the diameter of a corresponding recording medium RP can be detected by the output of a potentiometer 18j. At the beginning where the roll diameter is large, a carrying force is maintained at L and when the output of the potentiometer 18j detects that the roll diameter reaches a predetermined diameter N, a cam 19g is rotated to turn a rocking arm 19e. Then, the nip force of an upper carrying roller 10b and an energizing roller 10c is strengthened to increase the carrying force to H. Even if the roll diameter becomes smaller and the braking force increases, the difference between the braking force and carrying force is maintained at a proper quantity to enable maintaining the stable carrier operation of the recording medium RP.
