Patent JP-S6199403-A (JP)
Title: Amplitude limiter
Inventor: KAWAHARA TAKESHI
IPC: H03D3/24
Filed: 1984-10-19
Abstract: PURPOSE:To improve the S/N by providing an intermediate frequency amplifying part with an automatic gain control circuit in the preceding stage of a locking amplifier. CONSTITUTION:The first intermediate frequency signal has the frequency converted to, for example, 134.26MHz in a tuner for satellite broadcast reception. The second intermediate frequency signal is inputted to an intermediate frequency amplifier 2 with an AGC circuit to obtain the output having a certain output level. The output signal of this amplifier 2 is inputted to a locking amplifier 14. An intermediate frequency amplifier 10 and a high gain amplitude limiting circuit 12 raise the level of said second intermediate frequency signal to such value that the leading-in phenomenon occurs even for a high Q of la positive feedback circuit of the locking amplifier 14. The Q of the positive feedback circuit of the amplifier 14 is set to a high value so that the leading-in phenomenon occurs only within a maximum frequency transition range of the second intermediate frequency signal. Consequently, the leading-in phenomenon occurs in the amplifier 14 even if the Q of the positive feedback circuit is high, and the amplifier 14 is oscillated synchronously with the frequency of the second intermediate frequency signal.

Title: Convolver optimizing bias circuit
Inventor: OKAGAKI HIROYUKI
IPC: H03H9/72
Filed: 1988-09-02
Abstract: PURPOSE:To sharply reduce the worming-up time of an SAW convolver at the time of bias impression so as to improve the temperature characteristics by always monitoring the C-quantity of the gate electrode of the convolver and controlling a bias voltage so that the C quantity can become equal to the capacity Cop at the time of the optimum bias. CONSTITUTION:A convolver phase circuit 10 is constituted of a convolver 1 and LC-band filter composed of inductance L2 connected with a DC-cut capacitor C2 in series. Similarly, a reference phase circuit 11 is constituted of an impedance circuit which equivalently substitutes for convolver and LC-band filter composed of inductance L1 connected with a DC-cut capacitor C1 in series, with the impedance circuit and LC-band filter being connected in parallel with each other. The oscillation frequency of an oscillator(OSC) 12 is set so that the oscillation frequency can become the resonance frequency of each phase circuit and, at the same time, the oscillation circuit is set to a value other than the operating frequency of the convolver 1 by C0. Therefore, when the Cr and gr of the reference phase circuit are matched to the Cop and Gop of the convolver at the time of the optimum bias, phase outputs of each phase device coincide with each other when the bias of the convolver is optimized.

Title: Vibration type force transducing mechanism
Inventor: KOBAYASHI MASAAKI
IPC: G01L1/10
Filed: 1987-09-04
Abstract: PURPOSE:To perform high-accuracy force measurement by constituting a secondary vibration system which has a lower natural oscillation frequency than the basic frequency of an arcuate or tuning-fork vibrator by using a weight and a spring, and coupling it additionally with both sides or one side of the vibrator. CONSTITUTION:Vibration mechanisms 8 are formed integrally at both ends of the vibrator 4. The mechanism 8 is the secondary vibration system which has the longitudinal natural vibration frequency determined by the spring coefficient of the ring spring 9 and the mass of the weight 10 including bar 11. Then when static force F to be measured is applied to the mechanism 8, the spring 9 expands slightly, but the presence of the weight 10 is irrelevant to the transmission for the force F to be measured and a measurement result has no difference regardless of whether or not there is the mechanism 8. Further, the natural oscillation frequency of the mechanisms 8 can be set much smaller than the basic frequency of the of the vibrator 4 to the outside is reduce and the influence of external vibration is also small. Thus, the high-accuracy measurement is performed.

Title: Controlling method for reason
Inventor: YOSHIDA HIROYUKI
IPC: G06F17/30
Filed: 1986-09-19
Abstract: PURPOSE:To attain bidirectional rapid search by forming a link as a main body and forming network expression connecting a bidirectional pointer between a link corresponding to an intermediate result and a final conclusion and another link. CONSTITUTION:When a problem setting system body 1 detects the contradiction of a conclusion, the body 1 inquires the reason of an inference to a reason reference part 23 to be a submodule of a network control part 2 and the reference part 23 returns only leaves of the tree of the reason regarding a specified ink as its root by referring network expression 4 to the body 1 as a result. If the body 1 detects an error from the returned hypothesis or input data or when a user detects an error in the input data on the way of use and corrects the error, the body 1 commands an influence control part 25 to annual the inference. Then, the influence control part 25 deletes all the links up to the root along the tree of the reason regarding the specified links as leaves by referring the network expression 4 from a storage area. Thus, the tree of the reason can be rapidly and bidrectionally followed.

Title: Reference voltage generating circuit
Inventor: SUGINO HIROYUKI
IPC: G05F3/26
Filed: 1982-12-16
Abstract: PURPOSE:To decrease the temperature dependency of a current flowing to each transistor (TR) by making the gate shape (width/length) of the 1st TR larger than that of the 3rd TR. CONSTITUTION:In designing a P-MOS2 and a P-MOS5 so as to constitute a current mirror circuit, a current value flowing to an N-MOS1 and an N-MOS4 is made equal. Then, the gate shape (width W1/length L1) of the N-MOS1 is set as large as several times that (width W4/length L4) of the N-MOS4. The threshold voltage value of the N-MOS1 and the N-MOS4 is decided so as to form a current value flowing to each TR to be I0 at room temperature. Since the gate shape (W/L) of the N-MOS1 is made several times as large in the shape as the N-MOS4, when a resistance value R is increased at high temperatures and the current I0 starts decreasing, the drain-source voltage difference of the N- MOS1 and the N-MOS4 is increased, and the current is decreased only to IB. When the amount of change in the current is small, that of a reference voltage VOUT is decreased.

Title: Controller
Inventor: TOKUNAMI TAKAO
IPC: H02J7/00
Filed: 1991-09-03
Abstract: PURPOSE:To prevent the malfunctioning of a microcomputer built in a controller for device control, in the assembling process of a gas shut-off valve. CONSTITUTION:Current IM by a battery 32 for a power source flows into a microcomputer 31 through a short-circuiting lead 5c, provided in a connecting element 5b of a connector 5 having a couple of connecting elements 5a and 5b for connecting a controller 3 and a gas shut-off valve 1 electrically. When the connecting elements 5a and 5b are not linked before the assembly, the current IM does not flow. Accordingly, handling becomes easy as the microcomputer 31 does not malfunction by external noise such as static electricity, etc., before the assembly of the device. Besides, the assembly work can be rationalized by excluding reset work having possible malfunctioning from the assembling process. Incidentally, the addition of the short-circuiting lead does not increase the processes of the assembly work, as they are electrically connected automatically at the time of the linkage of the connector.
