Title: Automatic tracking device
Inventor: IWASAKI YASUO
IPC: G11B5/588
Filed: 1985-02-08
Abstract: PURPOSE:To make possible optimum scanning by executing the control by which the levels of the RF signals at at least >=2 sampling points in one field of the same head are maximized. CONSTITUTION:The envelope is subjected to sample holding at 3 points (in order of sample holding circuits 3, 10, 15) in one field period of the same head. Control circuits 6, 13, 18 operate respectively independently and repeatedly to change the impressed voltage in the same direction until the envelope decreases as compared to the previous frame by changing the impressed voltage of a head driving element 27, for example, increasing the same and comparing the voltage with the envelope at the same point of the next frame. The circuits 6, 13, 18 invert respectively independently the change direction of the voltage impressed to the element 27 if the envelope of the succeeding frame is smaller then the envelope at the same point of the previous frame. The impressed voltage which is so time divided as to maximize the respective envelope outputs at each point of the one field of the same head changes to attain the stable point in the above-mentioned manner.

When the sensor output level lowers and the time of cutting the threshold value V+h delays by DELTAt, write starting delays and a printed image is disturbed. Therefore, the sensor output is memorized and negative feedback is added to an amplifier to keep the sensor level constant.

Title: Decoder circuit
Inventor: TAGUCHI SHIGEMITSU
IPC: G11C11/413
Filed: 1983-02-15
Abstract: PURPOSE:To attain ease of processing of plural signals by constituting a group of gate circuits with a switch switched by the 1st signal and leading the 2nd signal to its output and a switch switched by the 1st signal and leading a prescribed value of ''0'' or ''1'' level to the same output. CONSTITUTION:When control signals R, S are logical ''0'', ''1'' respectively, Q2 and Q4 are nonconductive, and the circuit acts like a transfer gate where Q1, Q3 are conductive and nonconductive respectively with ''1'', ''0'' level of a gate signal X and the signals A and C are transmitted mutually at the conduction. When both the signals R, S are logical ''1'' and a signal V is logical ''0'', an X+ S is logical ''1'' and the Q4 is nonconductive. When the X is logical ''0'' and the Q1, Q3 are nonconductive, the Q2 is conductive to bring the output C to the ''0'' level the same as the level of the signal V. When the X is logical ''1'', the Q2 is nonconductive, and since the circuit plays a role of the said transfer gate, the output C is A.X as a whole. In replacing the signals X, X', the output C becomes A.(X').

Abstract: PURPOSE:To surely catch a self-station line while preventing the generation of asynchronous interference due to a bust signal from another station at the time of allocating a channel at a base station by executing time division multiple access among one base station and plural mobile stations. CONSTITUTION:A time slot allocation control part 5 stores the trailing edges of respective other-station burst signal slots measured by a counter 4 over a 1/2 frame period and counter values at the trailing edges in a RAM 50 and finds out a difference between plural values to detect the longenst silent section. When the detected longest silent section is longer than the time length of one time slot, the control part 5 commands a timing pulse generating circuit 6 to generate a transmitting/receiving slot timing pulse so as to obtain timing matched with the center position of a time slot to be allocated to the center position of the longest silent section after checking the possibility of no generation of synchronous interference. When there is no received signal or the longest silent section is short, the control part 5 sends a line switching request signal to a control part 7.

Abstract: PURPOSE:To prevent remained washing and damage to an airframe due to unusual approach to a washing unit by correcting the dislocated parking position of an aircraft introduced in a washing field by means of a coordinate converting means for converting a reference coordinate system into a parking coordinate system and by correcting the deflection deformation of the rear fuselage of the airframe and the deflection deformation of a main wing by means of a quadratic curve converting means. CONSTITUTION:The teaching point Tp' [X', Y', Z'] on a base data expresses the point of a parking coordinate. Each P car is operated by a reference coordinate system. Thus, in playback, the teaching point Tp [X, Y, Z] on the reference coordinate system is obtained. Data correction calculation is done for each axis so that the brush tip may be Tp. Deflection DELTAZ at any position y of the rear fuselage at a reference position of Y is expressed in the quadratic expression. Deflection DELTAZi at a position on a main wing at a reference position of X is expressed in the quadratic expression. The washing data of the rear fuselage, upper surface of main wing, lower surface of main wing units are corrected, using these expressions.

Abstract: PURPOSE:To obtain a light chopper useful in characteristic measurement for optical communication system, photo-devices and others by an arrangement wherein the lens is disposed in such a way that incident light is focused on the light chopping means arranged between two lenses. CONSTITUTION:Light introduced from a connector 15 connecting with optical fibers is image-transformed by a lens 11 so as to be focused on a shutter 14 opened or closed at the natural frequency of a tuning fork vibrator 13. The interrupted light enters into a lens 16 and then focuses so as to enter into optical fibers connecting with a connector 16. In this arrangement, when resonant frequency of the tuning fork vibrator is set at 280Hz, vibration of 400mum is produced with the application of 20Vpp, and the rod lenses are disposed to make the image transformation of 1:1 therebetween, the diameter of the focused light becomes 60mum upon connecting to optical fibers with the core diameter of 60mum. Rising and falling times of thus arranged light chopper become about 50mus and thus light pulse very near to a square wave is obtained. By so doing, it becomes possible to provide the light chopper useful in characteristic measurement for optical communication system, photo- device and others.
