摘要： PURPOSE:To improve the sharpness of a grindstone and to reduce the wear thereof, by covering a CBN grain or diamond grain with the resin of higher wear resistance compared with that of a resin bond. CONSTITUTION:A CBN grain or diamond grain 10 is taken as a resin bonded grindstone by dispersing it in a resin bond 12. In this case the CBN grain or diamond grain 10 is covered by the resin 20 of higher wear resistance compared with that of the resin bond 12. Now, the resin 20 of high wear resistance means the resin of the same material as the conventional resin bond or different material of high hardness and high wear resistance, for example of a phenol resin, an epoxy resin, a polyimide resin, etc., and moreover it means that which adds a hard particle to either of these.

摘要： PURPOSE:To constrain the fall of the abrasive grain of CBN grains or diamond grain and to reduce the wear of a grindstone by coating a metal coating layer by the resin of higher wear resistance compared to a resin bond. CONSTITUTION:CBN grain or diamond grain 10 having a metal coating layer 11 on the external surface is taken as the resin bond grindstone dispersing it in a resin bond 12. In that case, a metal coating layer 11 is covered by the resin 20 of higher wear resistance compared to the resin bond 12. As a result, the fall of the abrasive grain of CBN grain or diamond grain 10 can be restrained.

摘要： PROBLEM TO BE SOLVED: To easily and accurately adjust a stroke by providing a cylinder main body and a movable cylinder end wall threadedly engaged with the piston sliding directional end part of the cylinder body and capable of adjusting a sliding stroke of a piston by adjusting a threadedly engaging position. SOLUTION: A noncircular hole 38 of a movable cylinder end wall 34 is contained in the area of a noncircular hole 48 of a lock nut 46. Thus, since a tool can be applied to the noncircular hole 38 through the noncircular hole 48, there is no need to remove the lock nut 46 when threadedly engaging/ positioning the movable cylinder end wall 34, and since a required process is only to loosen the lock nut in a range required for an adjustment, workability is improved. A positional adjustment of the movable cylinder end wall 34, that is, a stroke adjustment of a piston 12 can be precisely, simply and easily made by a male screw 36 of the outer peripheral surface of the cylinder end wall 34, a pitch of a female screw 32 of the opening 30 inner peripheral surface of a cylinder body 16 threadedly engaging with this and a turning angle of the cylinder end wall 34.

摘要： PROBLEM TO BE SOLVED: To certainly prevent the malfunction of a speed change gear without deteriorating operational characteristics, by canceling a positioning signal as a wrong signal even when the positioning signal is outputted even to the other position over a neutral position. SOLUTION: Even when a change lever 61 is swung to reverse position sides by the reaction of the energization force of a spring 116 and there is a DOWN or UP input after a change lever 61 is temporarily operated on an UP position side or a DOWN position side, an input signal by these reaction can be satisfactorily canceled. Therefore, wrong execution of speed change control can be favorably prevented and the malfunction of the transmission may not occur at all without deteriorating the operational characteristics of the change lever 61 due to strengthening of the energization force of a detent spring 106 and/or the engaging force of a recess 112.

摘要： PROBLEM TO BE SOLVED: To certainly grasp for a driver whether a clutch is disconnected or connected at the present time by providing notifying means which notifies the driver of a vehicle that the clutch is disconnected when automatically disconnected by disconnection control means. SOLUTION: In the case that once control to stop is executed, automatic clutch disconnection is discriminated whether or not it is switched on at the present time (S40), and if it is No, it is discriminated whether or not a clutch pedal is stepped on (S42). In the case that the result of this discrimination is Yes, it is withdrawn from a stopping control routine without doing anything, and it No, a select range is discriminated whether or not it is in an N range (S44). If the result of this discrimination is Yes, it is withdrawn from the stopping control routine without doing anything, and if No, the automatic clutch disconnection is switched ON, and a clutch device is automatically disconnected (S46). Hereat, voice is spoken from a buzzer, and also a numeral display part on a gear stage display disc is flickered (S48).

摘要： PROBLEM TO BE SOLVED: To discriminate a disengaged state when a clutch is disengaged by a method wherein when it is detected that a vehicle is stopped and it is detected that a vehicle is not in a running state or a driver effects no drive operation, it is announced to a driver that a clutch mechanism is in a disengagement state. SOLUTION: In a semiautomatic T/M control unit 11, when it is detected from signals from a vehicle stop state detecting means and an operation state detecting means that a vehicle is in a stop state, a clutch mechanism 2 is automatically switched to a disengagement state by a clutch control means. When a clutch mechanism 2 is set to the disengagement state, it is detected that a driver is not in a driving state, an alarm is sounded by an alarm buzzer 14. Further, after the lapse of a given time starting from shift of the clutch mechanism 2 to a disengagement state, an alarm is sounded and after a gear position at a gear shift mechanism 3A is shifted to a neutral position, a clutch is engaged and it is prevented from occurring that a vehicle is started when a driver is not in a drive state.

摘要： PROBLEM TO BE SOLVED: To inform the driver the completion of gear shift by causing accelerator pedal stepping reaction to be changed by means of a stepping reaction adjusting means when it is detected by a speed shifting position detecting means that an operation for shifting speed is being carried out. SOLUTION: A piston member 9A-2 is driven by pressurized air inside an air tank 31 being fed to the air supply chamber 9A-3 of an air cylinder 9A and reaction with respect to an accelerator pedal 7 is increased. When it is detected by a speed shifting position detecting means 8 that speed change to the starting speed of the transmission is completed, a control signal for driving a magnet valve 9B is cut off and energized by the energizing force of a return spring 9B-1. An accelerator pedal reaction variation mechanism 9 is provided and a driver is informed of the completion of the gear shift by the change of the reaction of the accelerator pedal 7 in accordance with the situation of the gear shift.

摘要： PROBLEM TO BE SOLVED: To automatically disconnect a clutch when an engine is stopped at a low cost in a clutch control device suitable for a semi-automatic transmission device provided with the manual shift mode and the automatic shift mode by the remote control. SOLUTION: An engine 1, a clutch mechanism 2, an actuator 2A for clutch, a clutch output number of revolution detecting means 22, a brake detecting means 70 to detect the operation of a brake device, a vehicle speed detecting means 21, a stop judging means 50 to judge the stop of a vehicle, and a control means 11 are provided. The stop detecting means 50 judges the stop of the vehicle based on the information from the clutch output number of revolution detecting means 22, the brake detecting means 70, and the vehicle speed detecting means 21. When a judgment is made by the stop judging means 50 that the vehicle is stopped, operation of the actuator 2A for clutch is controlled so as to disconnect the clutch mechanism 2 based on the control signal from the control means 11.

摘要： PROBLEM TO BE SOLVED: To accelerate a vehicle with good responsiveness by stopping the control by a second fuel control means and switching it to the control by a first fuel control means when a clutch pedal is operated at a point of time when the shift is ended during the operation of a clutch control means. SOLUTION: When a clutch pedal is still in operation even at a point of time when the present number of speeds is displayed on a shift stage display board after the shift is ended, the output of a pseudo accelerator opening signal VAC is immediately stopped, and the accelerator opening signal is set to the present accelerator opening signal VA according to the operating quantity of an accelerator pedal. Thus, when a driver confirms that the number of speeds is switched and operates the accelerator pedal, rack position Rw, or fuel injection quantity becomes a value according to the present accelerator opening VA. Therefore, the time lug up to the eruption of an engine is eliminated, and the vehicle can be accelerated with good responsiveness according to the driver's intention.
