Title: Structure for fitting surface roughness measuring sensor
Inventor: KIMURA NORIAKI
IPC: G01B15/00
Filed: 1991-11-28
Abstract: PURPOSE:To protect a surface roughness measuring sensor from a hostile external environment by housing the sensor in a wheel, with the sensor fitted to the rotating shaft of the wheel, and, at the same time, to enable the sensor to make accurate quantitative measurement by constantly maintaining the distance between the sensor and a surface section on which the wheel runs. CONSTITUTION:An inner wheel 22 forms an internal space 24 on the central outer periphery of the rotating shaft 14 of an idler wheel 12 together with a bearing plate 16. A sensor main body 10 is fitted to the lower surface of a fitting plate 48 fixed to the internal surface of the plate 16 below the shaft 14 in the space 24 and positioned immediately below the center of the shaft 14 so that its transmitting/receiving surface can be faced to the ground-contacting section of the wheel 12. The main body 10 having a built-in antenna detects a phase difference and measures the roughness of a surface 28 with which a tire 26 comes into contact by transmitting electromagnetic waves against the surface 28 and receiving reflected waves. The space 24 is isolated from the outside and protects the main body 10 from a hostile external environment. In addition, the sensor can make highly accurate quantitative measurement, since the wheel 12 moves upward and downward following the unevenness of the surface 28 while it maintains the height of the main body 10 constantly even when the surface 28 undulates.

Title: Gas shut-off method for gas pipe
Inventor: TANAKA HIDESATO
IPC: F16L55/12
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To safely conduct the connection construction work by inserting at least three balloons at positions where gas is shut off and introducing inactive gas into a plurality of partition chambers formed among each balloon to exhaust gas in a second partition chamber when balloons are inserted into a pipe and gas in a gas pipe is shut off. SOLUTION: When a pipe passage position at which work is done is shut off from a direction of gas flow 2, three balloons 4 are inserted in gas shut-off positions, and partition chambers 12, 13 are formed among each balloon 4. Next, inactive gas is introduced into the partition chamber 13 adjacent to a shut-off zone, 14 through an inactive gas pouring pipe 7, and gas in the adjacent partition chamber 12 is exhausted from a gas exhaust pipe 8. At this time, pressures of a gas pipe on upstream side 11, each partition chamber 12, 13, a shut-off zone 14, and a gas pipe on downstream side 17 are measured by pressure gauges 21 to 23 to keep a pressure in the partition chamber from which gas is exhausted at a lower pressure than other pressures.  Consequently, gas on the upstream side is extracted from the partition chamber 12 to eliminate a gas leakage into the shut-off zone 14 so that the work in the shut-off zone 14 can be done safely.

IPC: F02D13/02
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To improve knock performance without lowering output performance during heavy load operation in a variable valve system engine. SOLUTION: The target air quantity is computed (S1). At the time of low/ medium load, supercharging is stopped (S3), and intake valve closing timing IVC is computed from the target air quantity to control (S4). At the time of heavy load, the intake valve closing timing IVC is set to basic set timing set after BDC (S7) and thereafter delayed stepwise (S12). Supercharger output pressure is boosted to equalize the cylinder internal air quantity by a combination of each intake valve closing timing IVC to make an adjustment (S8, S13). With every combination, cylinder internal temperature after compression is estimated from intercooler output temperature and cylinder internal volume at the intake valve closing timing (S9, S14).  The combination wherein the estimated cylinder internal temperature after compression is lowest, is selected to determine the intake valve closing timing IVC at the time of heavy load (S15, S21).
