Title: Pseudo synchronization prevention circuit
Inventor: TAKAHASHI KOICHI
IPC: H04L7/08
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To easily and surely detect and prevent a pseudo synchronization state by providing a forced hunting circuit controlling a 1st frame synchronization circuit to be in hunting. SOLUTION: In the case synchronization is taken in a 1st frame synchronization circuit 101 while no frame synchronization is taken in a 2nd frame synchronization circuit 104, it is discriminated that a pseudo synchronization state is caused in the 1st frame synchronization circuit 101. In the operation of a forced hunting control circuit 102 in this case, the circuit 102 detects at first the 1st frame synchronization circuit 101 is in a frame synchronization state and the 2nd frame synchronization circuit 104 is in a frame asynchronization state. Only when the 2nd frame synchronization circuit 104 is in a frame asynchronization state even after a prescribed time of τ1, forced hunting is applied to the 1st frame synchronization circuit 101 for a prescribed time τ2 to lock the frame of the 1st frame synchronization circuit 101 forcibly.

Filed: 1980-07-18
Abstract: PURPOSE:To realize an automatic loading system having a high success factor, by switching the rotational frequency of a file reel after detecting that the tip of a tape led from the file reel has reached the prescribed position of the tape path. CONSTITUTION:If a tip 5a of tape 5 led from a file reel 2 is not detected by a sensor 10a, a reference voltage switching circuit 17 is controlled via an AND circuit 16.

Abstract: PROBLEM TO BE SOLVED: To positively provide transmissive light and reflected light with fresh color tone by containing at least several types of powder with interference colors. SOLUTION: A semi-transmissive reflecting plate 42 contains titanium dioxide coated micas 14a, 14b. Micas 10a, 10b are formed in scale shape, which is coated with titanium dioxide 12a, 12b in a thin layer. For transmissive light or reflected light from the semi-transmissive reflecting plate 42 to be obtained with interference colors of desired tone, the layer thickness and abundance ratio of these titanium dioxide coated micas are considered. A light passage difference between the reflected lights 20a (20b), 22a (22b), or the layer thickness of the titanium dioxide 12a, 12b is changed to obtain various interference colors, red, violet, blue, green, etc.  In this way, the transmissive light 24a (24b) in additive complementary color relationship to the interference colors by the reflected lights 20a (20b) and 22a (22b) is obtained by the various interference colors, green, light yellow, yellow, red, etc.

Abstract: PURPOSE: To prevent a misoperation of the program due to the abnormal drop of a voltage of the power source, by providing a sensing means for detecting the abnormal voltage drop of the power source according to the starting operation of an engine and turning off the power source circuit for a control unit with an operation of its output.  
     CONSTITUTION: If a key switch 2 is turned on and a starter switch 3 is turned on, a large current instantaneously flows in a starter motor 4 from a bettery 1 to cause  an abnormal voltage drop in the battery 1. Then a turn-on operation of the starter switch 3 can be sensed and a relay 6 works to open a normally-closed contact 6a. This causes a connection state between the battery 1 and a control unit 8 to be disconnected, thus an automatic control can be prevented from misoperation when said starting operation is performed. After a completion of engine cranking, the contact 6a of the relay 6 is again turned on to be closed according to a turn-off operation of the starter switch 3, and the control unit 8 is connected to the battery 1.

Abstract: PURPOSE:To enable the detection of a phase difference DELTAtheta with good sensitivity by forming two sets of separated optical paths, detecting cos(DELTAtheta) and sin (DELTAtheta) in the respective separated optical paths, making the functions for the linear combination of both and utilizing the function of the best sensitivity. CONSTITUTION:The outputs of photodetectors 11, 12, 13, 14 are designated as D1, D2, D3, D4. Since there are pi/2 phase shifters in the separated optical paths, the output of the D1 is D1=2E0<2>(1+sinDELTAtheta). The output of the D2 is D=BE0<2> (1-sinDELTAtheta). From these equations, sin(DELTAtheta) is determined in the following way: sin(DELTAtheta)(D1-D2)/(D1+D2); similarly, cosDELTAtheta is determined by the following equation: cosDELTAtheta=(D3-D4)/(D3+D4). The n-pieces of following eigenfunctions are defined in the -pi/2<DELTAtheta<pi/2 range from sinDELTAtheta and cosDELTAtheta: Si=ai1sinDELTAtheta+ ai2cosDELTAtheta, (where i=1, 2,..., n) and DELTAtheta is determined from the value of the function Si.
