Title: Material clogging detector
Inventor: KUREI TETSUJI
IPC: B65G53/66
Filed: 1982-04-12
Abstract: PURPOSE:To detect whether the pulse interval of reset signals is long or short, monitor the condition of flow of the material, and detect clogging of the material in such a way that time limiting relays are actuated by means of a limit switch which is worked by the action of a balancing rod equipped with a material receptacle at one end. CONSTITUTION:Material 2 from a hopper 4 starts to collect in a material receptacle 8 and a balancing rod 9 taps a limit switch 12, when the equilibrium between the side of the receptacle 8 and the side of a weight 11 is broken down. When the balancing rod 9 is tilted, the material 2 gets spilt into a hopper 4, the rod 9 regains equilibrium, and when the material 2 is kept running without clogging the passage, the rod 9 repeats its horizontal and tilting posture. When the pulse interval between reset signals outputted from the limit switch 12 changes, showing that clogging is gradually initiated, on the basis of flow rate of the material 2, the pulse intervals grow longer, and the flow rate of the material 2 is monitored by means of cooperated action of time limiting relays TRY1 and TRY2 in a ditecting circuit 13.

Title: Frame synchronizing system
Inventor: YOSHIFUJI HIROTERU
IPC: H04J3/06
Filed: 1990-03-09
Abstract: PURPOSE:To prevent pseudo synchronization by taking frame synchronization depending on a synchronization pattern comprising a 1st synchronization pattern and a 2nd synchronization pattern whose location in a frame changes by means of a pointer sent out after a prescribed time from the 1st synchronization pattern. CONSTITUTION:Frame synchronization is taken by a synchronization pattern comprising a 1st synchronization pattern 8a sent at each frame synchronization in one frame and a 2nd frame synchronization pattern 8b whose location in a frame changes by means of a pointer sent out after a prescribed time from the 1st synchronization pattern. That is, the point of the pointer 11 changes irregularly for each frame, and the position of the 2nd synchronization pattern 8b is fluctuated irregularly for each frame. Thus, the probability of taking pseudo synchronization is made almost zero.

Title: Delay/racing check method of flip-flop
Inventor: KAWAMURA HACHIRO
IPC: G01R31/302
Filed: 1986-03-18
Abstract: PURPOSE:To make it possible to check delay/racing on the basis of the accurate shift of timing, by comparing the delay value of a signal reaching the data input of a receiving side FF through a transmitting side FF with that of the clock signal of the receiving side FF to perform checking. CONSTITUTION:With respect to a logical block divided into a plurality of ones, the delay values up to the clock pins (c), (d) of FFA and FFB are integrated as an average value. Next, the first branch point (b) is searched by the reverse tracking from the pins (c), (d). Subsequently, with due regard to the irregularity of respective delay elements in order to calculate the delay values from the point (b) to the pins on the basis of the timing at the point (b), the max. delay value and the min. delay value are integrated. Next, in order to calculate the delay value from the point (b) to the data input pin (e) of FFB through FFA, the max. and min. delay values are integrated. Then delay is checked, the min. value from the pin (b) to the pin (d) is compared with the max. value from the point (b) to the pin (e). When racing is checked, the max. value between the points (b), (d) is compared with the min. value between the points (b), (e).

Title: Focus position controller
Inventor: ONISHI HIROFUMI
IPC: G11B7/09
Filed: 1988-03-14
Abstract: PURPOSE:To automatically control the gain of a focus error signal by dividing the level of said signal by a level accordant with its gain and using this divided focus error signal to control the focused position of a beam. CONSTITUTION:The gains of the focus error signals a1, a2 and a3 received from a focus error signal detecting part 1 are changed by the change of characteristics due to the change of sensitivity, the secular change, the ambient temperature change, etc., of a semiconductor laser which radiates a beam and a receiving element for the reflected light. In the same way, the maximum values aMAX1, aMAX2 and aMAX3 of signals a1, a2 and a3 are also changed. These signals are divided by their maximum values respectively so that the gain differences of said signals are offset. As a result, these focus error signals are free from the characteristic errors due to the change of sensitivity, the secular change, the ambient temperature change, etc., of a semiconductor laser which radiates a beam or a receiving element for reflected light. In such a way, the gains of the focus error signals can be automatically controlled.

Filed: 1993-03-19
Abstract: PURPOSE:To allow a receiver side to separate plural pieces of additional information correctly when a sender side multiplexes the plural pieces of additional information to a TV signal and sends the resulting signal. CONSTITUTION:An identification signal generator 8 on a sender side generates an identification signal, a synthesizer 9 multiplexes plural additional information sets onto a TV signal by using the identification signal and the resulting signal is sent, and the identification signal is multiplexed to part of scanning lines at a changeover device 9 and the result is sent. Thus, when the sender side sends the multiplexed plural additional information sets while sending the identification signal, the receiver side extracts the received identification signal and separates correctly the plural additional information sets by using the extracted identification signal.

Abstract: PURPOSE:To lower the cost of the apparatus, by setting the excitation frequencies of first and second ultrasonic light frequency modulators to be so different that the frequency modulated wave will be detected with the low frequency equal to the differential frequency therebetween as carrier frequency. CONSTITUTION:The light beam emitted from a semiconductor laser 11 is made incident into a beam divider/surface elastic wave light frequency modulator 12 to be made a parallel flux with a geodesic lens (GL)12b, which is divided into a black reflected light modulated in the frequency and a 0 order transmission light not modulated in the frequency by a surface elastic wave of an ultrasonic wave of about 100MHz excited with an exciting electrode 12a.

Filed: 1984-03-30
Abstract: PURPOSE:To increase the use efficiency of a circuit by identifying whether a call starts in the beginning or ending of the same zone for securing a call time, and varying the number of block zones. CONSTITUTION:For example, when an up mobile station in an E zone among base station zones originates, A-G zones 102 are blocked. Namely, the number of blocked zones is so judged that when the mobile station is in the beginning of the presence zone, the presence zone and one front zone corresponds to the secured call time and when the station is close to the end of the presence zone, one rear zone and four front zones are included. A zone switching signal is received and a timer which detects zones is put in operation to measure the position of a train; when a hook signal for the start of a call arrives, a signal of blocking A is sent corresponding to the train position before the middle of the presence zone on the basis of the collation result of the timer circuit and a signal of blocking B is sent out corresponding to the train position behind the middle of the zone. Those signals are received by a base station and an antenna signal is stopped to perform the blocking.
