Title: Anomaly detector of pressure sensor
Inventor: ISHIDA TAKASHI
IPC: F02D45/00
Filed: 1984-04-09
Abstract: PURPOSE:To certainly judge the anomaly of a transmission passage leading to a pressure sensor from a pressure sensor and a suction pipe by transmitting the pressure in the suction pipe of an internal-combustion engine to the pressure sensor through a connection pipe and judging anomaly if the detected output of the pressure sensor does not vary when the engine load varies. CONSTITUTION:A connection pipe 4 is opened onto the wall of a suction pipe on the downstream side of a throttle valve 3 and is made of rubber for introducing the pressure to a pressure sensor 5. In a controller 7, the pressure Pm in the suction pipe is detected, and anomaly is judged, and the fuel feeding amount to an engine and ignition timing are calculated. In the sensor anomaly judging processing, judgement of anomaly is performed in the following cases: the case where the engine is in cranking operation, not in the normal operation, and the output of the sensor does not vary over a prescribed value, and the case where the engine is in normal operation and the engine load is constant, or the pressure does not vary.

Title: Channel selection device of tuner
Inventor: AKUTSU EISAKU
IPC: H03J7/18
Filed: 1978-06-15
Abstract: PURPOSE: To secure a circulating channel selection for all other channels within a short time by supplying the clocks of the same number as the channel number to be selected to the channel selection device in sequence with the fixed time interval via the start signals.  
     CONSTITUTION: Sequential channel selection device 1 of the tuner contains the channel selection buttons to perform selection for 12 channels and capable of switching of the sequential channels via the forward signals sent from control circuit 2. When switch 5 is pressed to carry out the circulating channel selection, the clock signals are applied to circuit 2 from clock generator 4. Circuit 2 supplies these clock signals to duo-decimal counter 3 and device 1. As a result, device 1 selects the next channel in sequence. When counter 3 counts 12 units of the clock signal, circuit 2 stops the supply of the clocks to device 1 and also reset counter 3.

Abstract: PURPOSE:To measure the displacement of the pipe to be forced into ground and its circumferential friction by detecting strain produced in the plurality of resilient members arranged around the pipe in parallel to the axis of the pipe. CONSTITUTION:Two resilient members 5 are arranged around each of the pipes 2 which are forced into ground successively, almost all over the length of the pipe and in parallel and symmetrically with respect to the axis of the pipe. Each resilient member 5 is secured at one end to a fixture 7 fixed to the pipe 2 and at the other end to a displacement meter 6 fixed thereto.
