Abstract: PURPOSE:To obviate the tardy acceleration and secure the comfortable acceleration feeling by keeping aimed value at a constant value within a prescribed time when the degree of speed-change demand is large. CONSTITUTION:When the absolute value of the difference Ns-No' between the aimed engine revolution speed Ns in startionary case and the aimed engine revolution speed No' at present which correspond to the suction throttle opening- degree at present exceeds a prescribed value DELTANa, it is judged that the sharp speed change demand is present, and transition time control is carried-out up to the time t4 when the absolute value of the difference between the aimed engine revolution speed Ns in stationary case and the aimed engine revolution speed No after renewal becomes DELTANb. During the period other than the above-described, stationary time control is carried-out. As for transition time control, during the time ranging from the time t1 to the time t3 after the lapse of the first time Ta, No is held at the aimed engine revolution speed Ns1 corresponding to the suction throttle opening-degree theta1 at the time t1. In this case, Ta is the function of the differentiation value of theta.

Abstract: PROBLEM TO BE SOLVED: To eliminate streaks and improve inscription quality by controlling that an inscription position of the permiated laser beam at the time of scanning a given block overlaps the one at the time of scanning the block adjacent to the given block. SOLUTION: On the liquid crystal mask, a block with an inscription pattern divided in a longitudinal direction is displayed in sequence and then each block is so inscribed on the work as to overlap. Thereby, a lower density part of the laser density distribution overlaps 34, and forms a profile 32 in a depth direction of the work, and at an intermediate part 33 between each blocks, the inscription is made approximately the same depth as to the other part. In the result, streaks between each blocks is eliminated. In the case that the inscription pattern is divided in a horizontal direction, the situation is the same and the shallow engraving part between each block is eliminated by inscribing each block so as to overlap on the work.

Abstract: PURPOSE: To maintain airtightness between the corner seal and apex seal of rotary piston engine at the time when temperature of engine is raised, by plating the outer surface of corner seal with steel material and making the inside of corner seal with sintered alloy of a special composition having a high coefficient of thermal expansion.  
     CONSTITUTION: Although inner hole diameter of corner seal groove 4 is increased due to thermal expansion of rotor 3 at the time when temperature of engine is raised, airtightness between rotor 3 and corner seal groove 4 can be maintained since outer steel material 6 of corner seal 5 is also expanded correspondingly. At the same time, sintered alloy 7 filling the inside of said outer steel material 6 is expanded in a direction closing gap 7a for receiving the apex seal 2, that is, expansion of the clearance between apex seal 2 and the gap 7a is prevented, so that airtightness between them can be maintained. Here, sintered alloy on the inside of corner seal 5 is composed of 8W25wt% of Ni, 3.5W10wt% of Cu, 2.0wt% of C and remaining wt% of Fe, and coefficient of thermal expansion of the alloy is selected to be larger than that of rotor 3.

Title: Method for detecting abnormality of braking device
Inventor: MATSUDA KATSUSHI
IPC: B60T8/96
Filed: 1995-06-01
Abstract: PURPOSE: To correctly judge the abnormality of a braking device by making a judgment that the braking device is in an abnormal condition when the amplitude of the waveform component included in the braking torque to be outputted from a torque sensor is remarkably large compared with the normal value. CONSTITUTION: In a braking system to give the braking torque to wheel from a drum braking device 8, the braking torque is detected by a torque sensor 23 such as a strain gage, and the detected braking torque is inputted in an ECU 24 to make a judgment whether or not the drum braking device 8 is in an abnormal condition from the characteristics of the detected braking torque. That means, when the pressure of the air system or the stepping force by a pedal brake is stable, the mean value of the braking torque to be detected by the torque sensor and the amplitude of the waveform component included in the braking torque are calculated per rotation of the wheel.  The mean value of the braking torque is compared with the amplitude of the detected braking torque, and a judgment is made that the drum braking device 8 is in an abnormal condition when the amplitude of the braking torque is relatively large.
