Abstract: PURPOSE:To improve considerably the threshold value of an optical damage without decreasing efficiency by forming an optical waveguide layer by thermal diffusion of a metal and proton. CONSTITUTION:An optical deflector which is a thin film optical element is constituted of an LiNbO3 crystal substrate 1, an optical waveguide layer 2 consisting of titanium and proton, grating optical couplers 3, 4 and comb-shaped electrodes 5. HeNe laser light 6 having 6328lambda wavelength enters the inside of the layer 2 from the coupler 3, is diffracted by the surface acoustic wave 7 generated by adding RF power to the electrodes 5. The diffracted light is take out to the outside by the coupler 4. The thin film type optical element is prepared from an element having a thermally diffused layer 8 of Ti on the substrate 1. The layer 8 is implanted with proton to form a proton exchange layer 9 and is thermally diffused into the substrate in a heating furnace to form the optical waveguide layer 2.

Inventor: NAKATANI TOSHIO
IPC: B65H67/06
Filed: 1988-01-20
Abstract: PURPOSE:To reduce the manhours for adjustment by eliminating the spring-out of a bobbin and the entanglement of the united thread by arranging a bobbin for sewing machine which drops from a winder in a straight line into an inclined accommodating means through a guide body and accommodating said bobbin. CONSTITUTION:A bobbin 7 dropped from the thread winding mechanism of a winder contacts the bottom between the right and left sides 17 and 18 of a guide body 20, and immediately starts to revolve towards the short side 14 of a supporting body 16. A reaction due to the impact in drop is exceedingly small, and the bobbin 7 does not spring outside the guide body 20. The dropped bobbin 7 revolves in the reverse direction to the thread winding direction along the right and left pieces 17 and 18 of an accommodating means 11 and the bottom, and winds the thread wound onto a shaft. Therefore, the bobbin 7 which drops and revolves contacts the shorter piece 14 of the supporting body 16 successively and stops, and the spring outside the accommodating means 11 is suppressed. The both collars of the bobbin 7 are slightly exposed from the right and left pieces 17 and 18, and arranged in a straight line.

Title: Gps receiver, data demodulation method and inspection system therefor
Inventor: INADA TAKAO
IPC: G01S19/36
Filed: 1994-02-01
Abstract: PURPOSE:To constitute a reference frequency generator without requiring any TCXO(temperature compensated crystal oscillator) and to realize a stabilized data modulation. CONSTITUTION:The frequency deviation of a reference frequency generator 13 is measured by means of an inspection unit 20 at the time of shipment inspection, for example. The measured frequency deviation is stored in a nonvolatile memory 17 while being related with the temperature of a reference frequency generator 13 detected by a temperature sensor 14. When a GPS(Global Positioning System) receiver 10 is used, a CPU 16 reads out a frequency deviation corresponding to a temperature closest the current temperature detected by the temperature sensor 14 and sets an oscillation frequency, corresponding to the frequency deviation, in the NCO(numerically controlled oscillator) 151 of a signal processing ASIC 15. When the data is not demodulated suitably by the signal processing ASIC 15, the CPU 16 alters the oscillation frequency being set in the NCO 151. When the data is demodulated suitably, the frequency deviation associated therewith is stored in the nonvolatile memory 17 while being related with the output from the temperature sensor 14.

Abstract: PURPOSE:To record/reproduce a signal with high reliability by constituting a recording gate signal of a recording signal, and making each head edge of the recording signal coincident with that of the recording gate signal to compensate a tip pulse of a modulation output signal of a semiconductor laser surely. CONSTITUTION:A Q output of a D-FF12 rises at a high level by the head edge of the recording signal B supplied from a terminal 11 to form the head edge of a recording gate signal E.

Title: Stay supporting structure for overhead projector
Inventor: FUJISAWA SHUJI
IPC: G03B21/132
Filed: 1990-01-18
Abstract: PURPOSE:To surely eliminate the unsteadiness of a stay in a left and right direction with low machining accuracy by positioning the stay on each one side of two projection members with the aid of using moment acting on the stay. CONSTITUTION:Under a state that a head is loaded on the stay 3, the stay 3 is in a forward inclined posture and the head is loaded under a state that it is deviated on a side. As the result, the moment in a direction (B) and the moment in a direction (C) act on the stay 3. When the moment in the direction (B) acts on the stay 3, an upper positioning pin 44 abuts on the positioning surface 42a of a chamfer 42 and a lower positioning pin 45 abuts on the positioning surface 43a of a chamfer 43. Due to that, the inclination of the stay 3 is regulated and the stay 3 is kept to be in a vertical standing posture. Besides, when the moment in the direction (C) acts on the stay 3, a guide pin 40 abuts on the front surface of a chamfer for locking 41 and the inclination of the stay 3 in a forward direction is regulated. Thus, the stay 3 is kept to be in the standing posture by the low machining accuracy without being unstead ied in a back and forth direction and the left and right and right direction.
