Title: Multi-value identification circuit
Inventor: NAKAMURA YASUHISA
IPC: H04L25/49
Filed: 1985-02-22
Abstract: PURPOSE:To attain quick normal locking state even when a pseudo locking is obtained by using a part of a reproducing signal to form an error signal thereby applying the signal to a DC level control means when a decision circuit decides the pseudo locking state from the level of an input signal of an A/D converter. CONSTITUTION:When the state reaches the pseudo locking state, e.g., the level is positive, the level taken for the input signal to the A/D converter 4 is shifted positively to the 1st bit threshold value V1. Thus, the output voltage of a low pass filter 22 being a mean value of the input signal of the A/D converter 4 is shifted positively and exceeds a reference voltage V+ of the voltage comparator 23. Thus, a decision circuit 20 is as pseudo locking and outputs '0' as a decision signal 21. As a result, the 1st bit output B1 is selected by a switching circuit 19 and an output signal 8 is obtained, the output voltage of a low pass filter 11 averaging it has a larger positive value than the output voltage of the normal locking, the output voltage of the DC amplifier 2 is drawn largely toward the negative level by negative feedback control. As a result, a pseudo locking is released and normal locking is attained.

Title: Device for measuring stress acting on mechanical part and attaching method thereof
Inventor: JIERAARU JISANJIE
IPC: G01L1/00
Filed: 1994-02-08
Abstract: PURPOSE: To enable measurement of stress exerted on a mechanical part by connecting a plate on which strain gauges are attached to the mechanical part by a link coupling means and also outputting the measured result of stress acting on a gauge by means of electric signals. CONSTITUTION: For instance, at least one plate 2 and at least one strain gauge 3 are provided in a brake passage so as to generate an electric signal which is a function of measured strain. Furthermore, the gauge 3 is installed on the plate 2. A forming means 4 for an electric signal generated from the gauge 3 can be installed on the plate 2 causing its position to be close to the gauge 3. Accordingly, particularly even if any signal extremely low in its level can be prevented from being disturbed along a wire for a link. The strain gauge 3 is, for instance, a resistance body of Wheatstone bridge and subject to the minimum strain from the gauge 3, but owing to this gauge 3, the resistance and therefore, a signal for the bridge output are varied. The plate 2 and a machine part 1 are fixed so that stress may be entirely transmitted to the plate 2.

Title: Method and instrument for inspecting coil
Inventor: UORUFUGANGU TORAMUPERUTO
IPC: G01R31/72
Filed: 1990-02-14
Abstract: PURPOSE: To attain inspecting coils without adjustment process by man power and without phase discrimination type measuring device by performing measurement at a frequency where the voltage of the measuring coil for non-defected test piece becomes minimum. CONSTITUTION: A coil to be inspected (test piece) 1 is put in between an exciting coil 5 and a measuring coil 25. The magnetic field produced by the transmission coil connected to a single phase alternating current source 6 induces voltage in the test piece 1. At the same time, a stray magnetic field is generated from the transmission coil and generates voltage in the coil 25. When the exciting frequency is raised, a parasitic coil capacitance of the test piece 1 works more strongly. Therefore, a current flows also in a non-defected test piece 1, which generates magnetic field. At a frequency (500Hz to 100kHz), stray magnetic fields generated by the transmission coil and the test piece 1 cancel each other. At this frequency, the voltage in the coil 25 becomes minimum. If a turn short circuit exists in the test piece 1, the minimum voltage induced in the coil 25 is raised.  Thus, by evaluating this voltage, the existence of the turn short circuit can be judged.

Title: Control system for radio communication antenna
Inventor: TAKAHASHI HIDEHIRO
IPC: H04B7/02
Filed: 1978-03-27
Abstract: PURPOSE:To ensure an assured radio communication at the area where the field level falls down suddenly by the space standing wave by securing the sequential change of the radiation pattern of the antenna at the calling side and under transmission of the calling signals. CONSTITUTION:In case the calling signal is transmitted for calling slave unit 2 by master unit 1, wave guide element 3a and 3b of antenna 3 of unit 1 are turned mechanically to vary in sequence the radiation pattern of antenna 3, i.e., the directivity. A change shown in the figure, for example, is given to the field intensity at the position of unit 2 where the space standing wave can be generated via reflector 5 and 6. But the calling signal can be received from unit 1 regardless of the position of unit 2 by the change of the radiation pattern of the transmission antenna. Unit 2 gives the replay which is then detected by unit 1 to stop the change of the radiation pattern of the antenna. Thus, the steady communication is ensured thereafter.
