Title: Signal switch
Inventor: KOYAMA KAORU
IPC: H04B1/74
Filed: 1977-10-28
Abstract: PURPOSE: To make smooth adjustments possible with the wide variation width of an operation switching transfer time, by connecting a low-impedance driving current varying method to a least one winding of a plural number of relays.  
     CONSTITUTION: As substitutes for conventional resistances, the control relay circuit of a signal switch of a switching-time adjustment type employs transistors TR 1  and TR 2  in an emitter-follower form, and variable resistances VR 3  and VR 4  vary the base voltages in order to control current flowinf to realy windings RL 1  to RL 4 . In this case, driving impedance values of TR 1  and TR 2  are much less than resistances of relay windings RL 1  to RL 4 , so that even if VR 3  and VR 4  are adjusted, the variation for the resistance of a circuit connecting relay windings can be ignored. Characterstics indicating the vauration of operation start time (t) of a realy against winding current I of the relay are shown by curve line (a), which makes it possible to widen the variation width of the operation time in comparison with the conventional example [curve line (b)].

Title: Focus detection system
Inventor: OOSHIMA KEN
IPC: G02B7/32
Filed: 1980-09-17
Abstract: PURPOSE:To simplify an optical system and a level detecting circuit by detecting an in-focus state by using the intensity distribution of reflected luminous flux with which an array of photodetecting elements is irradiated in the focus detection system of an optical information reader. CONSTITUTION:Reflected light from a disk 6 is diverged, parallel or converged according to the (too close), (in-focus) or (too far) state of an optical condensation system. Therefore, light-intensity distribution on a photodetector array 10 set at right angles to the optical axis is gentle at a closer side based upon an in-focus state and steep at a farther side. For this purpose, an output near the optical axis is held 12 and halved by a divider 13 to obtain a threshold level, and a comparator 14 finds the number of elements generating outputs exceeding the threshold level. Namely, a half-value width is found and compared 15 with a reference width signal 16 to determine the output of a lens driving mechanism 17. Since the need for an optical image forming system for reflected luminous flux is eliminated, the size of a head is reduced.

Filed: 1990-05-22
Abstract: PURPOSE:To transmit a sound or a data service signal having the completely same capacity as a satellite broadcasting by a CATV or the like by limiting the band of a video signal and converting a sound signal to a signal caused by a carrier away from the main carrier frequency of the video signal. CONSTITUTION:Satellite broadcasting receivers 301 and 302 output an inputted satellite broadcasting signal 300 after converting it to digital signals 303 and 305 and on the other hand, video signals 304 and 306 having about 4.5MHz band width are demodulated and outputted. Digital signal conversion circuits 307 and 308 convert the digital signals 303 and 305 to 16 QAM signals 312 and 314 in the respective channels of the CATV and output them. Picture processing parts 309 and 310 output the video signals 304 and 306 after limiting the band to 4.18MHz for the normal ground system video signal. VSBAM modulators 316 and 317 execute VSBAM modulation to the band-limited video signals outputted from the picture processing parts 309 and 310 with the respective channels of the CATV as the carriers and output those signals. Thus, without enlarging the band width, the video signal and the digital signal similar to the same channel satellite broadcasting signal can be transmitted in the transmission system of the CATV or the like.

Title: Production of optical fiber
Inventor: MITA AKIRA
IPC: G02B6/00
Filed: 1977-10-31
Abstract: PURPOSE:To produce an optical fiber, which has no variation in refractive index in the form of  an annular ring, by introducing gases of glass material into a longitudinal hot portion of a quartz pipe, when it is intended to produce a communication glass fiber, which has a refractive index distribution of graded type, by the CVD method. CONSTITUTION:Glass material gases are injected into the opening 25 of a quartz pipe 21, while transversely moving the pipe 21, so that all the components of the material gases are simultaneously sedimented and separated in the portion (corresponding to that shown at 23), where the temperature takes the maximum by the heating process of a ring burner 22. After one sedimented layer has been formed, the composition of the material gases is changed, and the formation of the next separated layer is made. These steps are repeated. And, the residual gases, which have failed to react during the blowing step of the material gases, and the reaction products are always sucked and discharged during operation through a discharge duct 27. As a result, even at such a low temperature portion as can effect the reactions of germanium and boron which can react at a slightly lower temperature near the highest temperature range, these elements can be prevented from reacting and being sedimented.
