Title: Ultra-sonic invasion detector
Inventor: KONDOU MIKIO
IPC: G08B13/08
Filed: 1977-11-10
Abstract: PURPOSE: To prevent malfunction without damaging the detection performance for a moving body by dividing receiving signals into an upper-side band and a lower- side band in respect to a radiated ultra-sonic frequency and generating the detection output when a distribution state becomes unequal.  
     CONSTITUTION: This detector is constituted by oscillator circuit 1, frequency divider 2, 90° phase difference generation frequency divider circuit 3, amplifier circuit 4, wave transmitting element 5, wave receiving element 6, amplifier circuit 7, the first and the second right angle phase detector circuits 8 and 9, the first and the second low-pass filters 10 and 11, the first and the second phase difference detector circuits 14 and 15, and D/A converter circuit 20. Here, though circuits 8 and 9 have the phase difference of 90° to make the signal taking-out possible when the input is single side-band signals, they have the in-phass output when the input is the CSB wave having both side-bands. Since circuits 14 and 15 generate the output only when one of amplification shaping circuits 12 and 13 has the H-level output, opposite phase separation is possible, and in-phase components are also removed by the resistance coupling of circuit 20.

Title: Thin film transistor circuit
Inventor: TAKAHATA MASARU
IPC: H03K19/0185
Filed: 1988-06-03
Abstract: PURPOSE:To prevent the thermal destruction of a thin film transistor(TFT) and to attain high speed operation by connecting the outputs of second step and third step inverters respectively to the gates of the two TFTs in the inverter of a fourth step and fetching an output signal from the output of this inverter. CONSTITUTION:The three inverters are parallelly arranged between a power source voltage VDD and a ground and the outputs of the inverters in the second and third steps are respectively connected to the gates of TFTs Q7 and Q8 in the inverter which is connected between power source voltages VH and VL. Then, an output signal Vout is fetched from the output of this inverter. Thus, for the inverter excepting for the inverter in the first step, since either a driver TFT or a load TFT certainly goes to a turning-off condition, a direct current does not flow between the power source voltage and ground and the thermal destruction is not generated for the transistor. Then, since an input signal Vin is transferred by a ratio-less type inverter, whose current driving ability is large, the high speed operation of a circuit can be executed.

Title: Data communicating system
Inventor: UMEDA TOSHIHIKO
Filed: 1986-06-11
Abstract: PURPOSE:To improve the through-put of transmitting data and to use efficiently a line by controlling a transmission in accordance with a propagation delaying time on a line obtained from the arrival condition of a transmitted signal at the time of sharing the line between plural terminal stations. CONSTITUTION:From a transmitting part T of plural nodes 41-43 to share a line 1, the frame of a prescribed format is transmitted and received by a receiving part R of the node of an address. Between minimum terminal stations A and B of a line, the attenuating quantity when the frame is transmitted is obtained beforehand. At the receiving part R of the receiving side, the receiving level when the frame is received is investigated and the propagation delaying time on the line 1 between terminal stations is obtained. By the obtained delaying time, the mixing condition of the line is decided and transmission is controlled. Thus, the through-put performance of the transmitting data is improved and the using efficieny of the line as a whole can be improved.

Title: Cyclic transmission system
Inventor: SUMITA YUJI
IPC: H04L69/40
Filed: 1993-06-07
Abstract: PURPOSE:To prevent fault discrimination due to transmission of a default period in advance by setting default information in to a transmission frame sent from a terminal equipment to a LAN transmission line to allow a terminal equipment at a receiver side to revise a monitor time based on the information. CONSTITUTION:When a terminal equipment 12 is not aware of a transmission period set in advance in the transmission system and requires cyclic transmission, the terminal equipment 12 sets default information representing the transmission of a transmission frame for the default period into the transmission frame and sends the resulting frame. On the other hand, when other terminal equipment 12 receiving the transmission frame detects the default information set in the transmission frame, the terminal equipment 12 revises the transmission monitor time set in itself into a default monitor time. Since the default monitor time is set longer than the usual monitor time set in advance in the system, even when the default period is longer than the usual setting period, it is not discriminated to be an error.
