Title: Heterodyne system frequency conversion circuit
Inventor: FUJIWARA MASAHIRO
IPC: H04B1/16
Filed: 1989-05-23
Abstract: PURPOSE:To apply heterodyne system frequency conversion with high stability of an output signal by using an output of a local oscillator added with part of a reference signal as a local input of a double balanced mixer. CONSTITUTION:Even when a local oscillating frequency fL is fluctuated by obtaining a sum frequency component f3=f2+fL resulting from the output signal fL of a local oscillator 8 and an intermediate frequency f2 from the frequency- dividing the 3rd output through mixing, the frequency f3 follows to the fluctuation of the frequency fL. Moreover, a difference frequency f1=f-fL between part of a reference signal (f) whose frequency is (f) supplied from a terminal 1b and an output fL of the local oscillator 8 is extracted from a double balanced mixer DBM 7 to obtain a sum signal f4 whose frequency is f3 at a DBM 16. Thus, even when the frequency (f) of the reference signal and the measured signal is fluctuated, since the frequency f4 follows to the fluctuation, the output signal having always high frequency stability is extracted.

IPC: F16H63/40
Filed: 1989-05-25
Abstract: PURPOSE:To reduce the tractive force at the time of departure of a vehicle to a value lower than the cohesion between a wheel and a rail and prevent racing of the wheel by forming 2nd-speed engagement at the time of shift driving. CONSTITUTION:When a vehicle is departed, an engine 34 is first brought into idling state to fit either a positive rotating clutch 59 or a reversing clutch 61 to the forward direction of the vehicle, then a change gear clutch 38 is fitted, and also the output of the engine 34 is increased.

Title: Multiplex transmitter
Inventor: KOBAYASHI KENJI
IPC: H04L12/40
Filed: 1990-05-21
Abstract: PURPOSE:To receive information quickly by providing a transmission interval revision means sending an information signal repetitively to a transmission means at a prescribed time interval to the system. CONSTITUTION:Transmission information representing the transmission of an information message signal is outputted from a data transmission processing section 8 to a counter 7 being a transmission interval revision means to count number of times of sent information message transmission. When the number of times of transmission reaches a prescribed number of times or a reset signal is outputted from an input data analysis section 15, an operating interval revision signal is outputted to the data transmission processing section 8. Thus, the counter 7 allows the transmission processing section 8 to send the information signal for a prescribed period at a 1st prescribed time interval corresponding to the change state detection of the information signal and allows the transmission processing section 8 to repetitively send the information signal for a prescribed period at a 2nd prescribed time interval longer than the 1st prescribed time interval when the lapse of the prescribed period is discriminated. Thus, even when a station receiving the information signal is failed to transmit/receive the first information signal, the succeeding information signal is received immediately.
