Title: Coordinate reading device of phase inversion detecting system
Inventor: MORITA YOSHIYUKI
IPC: G06F3/046
Filed: 1985-05-21
Abstract: PURPOSE:To eliminate necessity of leading a reference signal from the same signal source with an exciting signal and make it possible to make a coordinate indicator wireless by providing a reference signal generating device that generates a reference signal identical with an exciting signal in a signal processing circuit. CONSTITUTION:A calling-on signal (e) induced by an exciting signal is inputted successively to the phase detector 12 and a calling-on signal detector 15 of a signal processing circuit. The signal inputted to the detector 15 is detected as a receiving wave detection signal (k), and converted to a gate signal (g) by an FF 16. On the other hand, a signal of 2<n> times exciting signal is outputted from a reference signal oscillator 17, and inputted to a counter 19 through a gate 18 opened by the gate signal (g). The counter 19 frequency divides the signal into (n) parts and outputs to a phase detector 12 as a reference signal (s). Accordingly, the reference signal (s) has similar phase relation to the calling-on signal, and therefore, the calling-on signal (e) can be converted to the phase detection signal (g) by the signal (s).

Title: Semiconductor laser
Inventor: MORI MASAKAZU
IPC: H01S3/063
Filed: 1983-06-17
Abstract: PURPOSE:To inhibit Fabry-Perot mode oscillation even in the case of a large degree of amplification by a method wherein both end surfaces are connected in ring form by means of a dielectric wave guide or a laser medium, in a distributed feedback type laser and a distributed reflection type laser. CONSTITUTION:Both the end surfaces of an active layer 5 are connected in ring form by means of the dielectric wave guide 7, resulting in the inhibition of the Fabry-Perot mode oscillation, in the distribution feedback type laser. At this time, the length of the wave guide 7 is taken larger than a coherence length. Such a manner does not allow said oscillation even in the case of the increase of the degree of amplification of the active layer 5, since both the end surfaces of the active layer 5 are constructed in ring form by means of the wave guide 7. Light is taken out by means of an optical fiber 9 from the active layer 5 via the wave guide 7 and an output coupling wave guide 8, there-fore the length from the active layer 5 is long, and then the influence of the reflection on the coupling part with the optical fiber 9 can be alleviated.

Filed: 1978-09-05
Abstract: PURPOSE: To form correct beveling by providing a vertical torch and an inclined torch in the torch unit that is always subjected to pressing force in direction of approach to the working plate and thereby making them keep a specified distance from the working plate and follow the surface.  
     CONSTITUTION: Set up is made to move the vertical torch 6 just above the setting line for cutting. Then, adjustment of the height of the tip of vertical torch 6 against the copying roller 21, adjustment of height and inclination of the inclined torch 7 and adjustment of adjusting arm 20 are made to cut specified beveling. When, the guide rod 12 is moved along a fixed locus, the torch guide head 17 moves in a horizontal plane having a fixed height from the floor. However, the torch unit follows the unevenness of the upper and lower faces of the steel plate 11 by the action of the spring 31 and copying roller 21 and no change occurs in relative position of the vertical torch 6 and inclined torch, and the steel plate 11. Thus, beveling of correct size and shape can be formed at all times.

Filed: 1991-05-15
Abstract: PURPOSE:To stabilize the oscillation frequency of the nonlinear optical effect conversion laser by comparing the detection signal from a temperature sensor provided to a laser light source with a reference voltage by a comparator and finding their difference voltage. CONSTITUTION:A 2nd feedback circuit consists principally of a temperature sensor 41, an amplifier 31, the comparator 35, a driver stage 37, and a Peltier element 39. A low-frequency component L is extracted from a heterodyne spectroscopy signal by branching and filtering, and the component is amplified and outputted to the comparator 35. The reference voltage for temperature setting is added to the signal of the low frequency component L from the amplifier 31 and inputted to one input terminal of the comparator 35 and a detection signal from the temperature sensor 41 corresponding to the surface temperature of a laser diode 11 is inputted to the other input terminal. The comparator 35 obtains the difference between both the input voltages and outputs it from its output terminal. The oscillation frequency of the laser diode 1 is therefore prevented from shifting corresponding to a temperature drift and held constant.
