Title: Surface acoustic wave filter device
Inventor: HORIO YASUBUMI
IPC: H03H9/64
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To improve GDT(group delay time) of a surface acoustic wave filter device and also improve the symmetry of its amplitude characteristics. SOLUTION: A λ/4 difference exists between the distance which a T.T.E(triple transit echo) generated by a 1st filter stage 11 is propagated before outputted from a signal output terminal 6 and the distance which a T.T.E generated by a 2nd filter stage 12 is propagated before being outputted from the signal output terminal 6 and then those T.T.E's can shifted a half wave from each other. Consequently, when a signal is outputted from the signal output terminal 6, its T.T.E's cancel each other, and consequently the GDT characteristics and the symmetry of the amplitude characteristics are both improved.

Title: Internal combustion engine starter
Inventor: YUMIYAMA SHIGERU
IPC: F02N15/02
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide, at low cost, an internal combustion engine starter that is free from abrupt stop of function although a roller bearing is frequently loaded with a radial load. SOLUTION: A retainer 54 is formed of engineering plastic such as nylon. When a bearing 50 is loaded with an excessive radial load, indentations and scaling are produced on raceway surfaces of inner and outer rings. As a result, the roller bearing loses its original performance, but it can retain bearing function. Thereafter, when the starter is operated, the retainer 54 made of plastic, which is more elastic and softer compared with a retainer made of metal, may be deformed but hardly broken instantaneously. Accordingly, broken pieces of the retainer hardly enter between the raceway surfaces and a rolling element 53. Even if some broken pieces enter between the raceway surfaces and the rolling element 53, the soft plastic pieces are easily worn between the steel raceway surfaces and the steel rolling element, thus preventing a bearing 50 from being locked.

Abstract: PURPOSE:To control to change the duty ratio of an output waveform to an ambient temperature change by matching to the temperature change of-the pinchoff of an FET and changing a bias voltage by a temperature compensating circuit. CONSTITUTION:A voltage converting part 2 is connected to the source side electrode S side of an FET 1, a voltage converting part 2 is connected, and on the other hand, a load circuit 4 such as a laser diode is connected to a drain electrode D side. The converting part 2 includes a temperature detecting part 3, a stabilized source voltage VS, in which the value is changed in accordance with the temperature detected by the detector 3, is supplied to a source electrode S of an FFT1. The voltage VS become lower at the time of the low temperature, the width of a voltage Vgs between gate sources is made narrow, on the other hand, the voltage becomes higher at the time of the high temperature, the width of the voltage Vgs is made wider and as such, the change is executed for the temperature. The temperature variation of the voltage VS is adjusted so as to be coincident to the variation of a pinchoff voltage Vp of the FET1. Thus, for the temperature change, the voltage VS is changed for the temperature change following the voltage Vp, and thus, the slice level of the input waveform is made always constant to the temperature.
