Title: Information device
Inventor: YOSHIMOTO KIYOUSUKE
IPC: G11B7/09
Filed: 1983-09-30
Abstract: PURPOSE:To improve the servocontrol performance with a simple and inexpensive circuit by obtaining an error signal from the difference among minimum values of plural data obtained from an approximately equal part of a recording medium where the intensity of signals at the area where an information signal is recorded than that of signals at the area where no information signal is recorded. CONSTITUTION:In a record mode a drive circuit 12 which modulates a light source 1 by an information signal works. Thus the energy density of a condenser spot rises repetitively over a level which changes the reflection factor of a recording medium in a groove of a guide track 6 and falls. In a reproduction mode the energy density is kept under the above-mentioned level. The track 6 is projected or depressed by 1/8 wavelength compared with the peripheral parts, and therefore the reflected beams of the inside and the outside produce an interference. The degree of interference differs between the inside and the outside when the condenser spot has a shift to the guide 6. Then a 2-split detector 11 has different outputs. Peak detecting circuits 14a and 14b detect the minimum value of the signal amplified by amplifiers 13a and 13b i.e., the signal value obtained when the output of the source 1 is set at a reproduction level and at the same time obtained at an area where the condenser spot does not exist in a recording bit. Then an arithmetic circuit 15 delivers an error signal from the minimum signal.

Title: Guiding method for unmanned carrier
Inventor: MIURA TOKUNORI
IPC: G05D1/02
Filed: 1985-08-19
Abstract: PURPOSE:To attain the drive control of an unmanned carrier in a wide range just with a single sensor by setting a sign body so that the boundary line between the sign matter and a non-sign body is set along the driving route of the carrier and detecting the position shift of the carrier by a sensor to control the steering amount with the output of said position shift detection. CONSTITUTION:A magnetic sign body 1 is set so that the edge side of the matter 1, i.e., the boundary line (l) with a non-sign body is set along the driving route of an unmanned carrier. A magnetic sensor 5 set on the carrier has the detecting characteristics to the driving route (l) as shown in the diagram. Thus the steering amount of the carrier is controlled to the right and the left when the detection output of the sensor 5 is positive and negative respectively. Then the carrier can travel automatically. Furthermore the maximum steering amount is secured for the carrier although the carrier has a big shift from the route (l) since the output of the sensor 5 keeps the positive or negative saturated output. Thus the position of the carrier can be finally corrected up to the route (l). In such a way, the drive of the unmanned carrier can be controlled in a wide range with a simple constitution.

Abstract: PROBLEM TO BE SOLVED: To attain the avoidance of a malicious telephone call or erroneous telephone call by sending a message requesting the input of a stored caller number through a control means when the caller number cannot be detected from an information signal, and reporting call incoming only when the caller number is detected within prescribed time and coincident with the registered number. SOLUTION: A control circuit 7 controls respective parts according to an operation program stored in a ROM 8 and a caller number detecting circuit 3 detects the presence/absence of the caller number in the information signal on a telephone line. When there is the caller number, the control circuit 7 sounds a bell 11 and performs call incoming processing but when there is no caller number, the message of 'Please input your telephone number' stored in a RAM 9 is sent to a caller. Only when the caller number is detected within the prescribed time by a DTMF detecting circuit 6 and coincident with the registered number, the control circuit 7 sounds the bell 11 and performs off-hook so that speaking is enabled. In the other case, the bell 11 is not sounded, on-hook is performed and speaking is not permitted so that the malicious telephone call or the like can be prevented.
