Title: Psk modulating circuit
Inventor: WAKABAYASHI NAOYUKI
IPC: H04L27/20
Filed: 1993-10-15
Abstract: PURPOSE:To prevent the amplitude change of the modulation output by stopping the resonance operation of a resonance circuit in the period of the phase change of modulation by a switch circuit and outputting the preserved energy after this change to eliminate damped oscillation and forcible oscillation of the amplitude at the phase change point. CONSTITUTION:When a switch circuit 22 is operated by a transmission code Data to switch the phase, the signal having a prescribed phase change waveform is outputted from an output amplifier 23. When the resonance operation of a resonance circuit 24 is stopped in the period of 180 phase change by a switch circuit 25 synchronously with this phase change, the electric energy in this period is preserved in a coil L. After the period of 180 deg. phase change in the circuit 25, the preserved electric energy is outputted, and a prescribed current flows to the coil L. Thus, damped oscillation or forcible oscillation is not, brought about in the amplitude at the phase change point, and the amplitude of the modulation output is not changed, and the output is outputted with the complete waveform (amplitude).

Abstract: PROBLEM TO BE SOLVED: To early detect and identify the occurrence of the abnormalites of parts around a timing belt by identifying the occurrence of such abnormalities when a temperature level detected with a temperature detection means exceeds a temperature level on a judgement line for temperature abnormalities in a timing belt case. SOLUTION: When an engine is operating, ECU 15 takes in the data of engine cooling water temperature, engine lubricating oil temperature, timing belt case internal temperature TB and the like, and first makes judgement as to whether or not the timing belt case internal temperature TB is acceptable, thereby making judgement as to whether or not the temperature is within an acceptable zone. When the judgement is affirmative, a calculation is made about temperature X corresponding either the engine cooling water temperature or the engine lubricating oil temperature. Then, judgement is made as to whether or not the timing belt case internal temperature TB is above the temperature X and when the temperature TB is above the temperature X, abnormalites are judged to be present.  Also, judgement is made as to whether or not the integrated number of revolutions after the rise of the temperature TB over the temperature X is equal to or below the preset number A. When the number exceeds the value of A, notice is given of necessity for checking or replacing parts around a timing belt.

Title: Brake pad and disc brake
Inventor: HARA YUKIO
IPC: F16D69/00
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a disc brake having a brake pad suitable for a draft type rotor. SOLUTION: A radially extending groove 76 having width increased toward the inner peripheral side of a rotor is formed in the central part in a peripheral direction of the friction material 72 of a brake pad and first and second friction members 78 and 80 are arranged on both sides of the groove 76. Further, the edges 82 and 84 on both sides, spaced away from each other in the peripheral direction of a rotor, of the friction material 72 are inclined in the radial direction of a disc rotor 30 and brought into a state to be in parallel to each other. Thus, the side edges 82 and 84 and the groove 76 of the friction material 72 are not brought into a state not to be parallel to the fin 48 of the disc rotor 30, and the generation of squeal during brake is suppressed.  Further, the rotor inner peripheral side edges 94 and 96 of the first and second friction materials 78 and 80 are further decreased in length than rotor outer peripheral side edges 90 and 92. Since the friction material 72 is formed such that an area on the side making contact with the outer peripheral part of the disc rotor 30 is increased to a value higher than a area on the side making contact with the inner peripheral part thereof, the occurrence of deviated wear of the friction material 72 is reduced.
