Title: Clutch control method
Inventor: IMAZATO KAZUNARI
IPC: F16D48/02
Filed: 1987-02-28
Abstract: PURPOSE:To shorten speed change time, by returning a pressure plate to a position in the way of stroke, when speed change other than first speed is started, and engaging a clutch again upon finish of speed change through a speed change gear. CONSTITUTION:A pressure plate 1d is returned to the way of entire stroke when automatic speed change is carried out through a speed change gear 3 except the first speed, so as to return the shortened distance to re-engagement state of a clutch board 1b as soon as switching of the speed change gear 3 is finished. Consequently, entire speed change time can be shortened for every speed change. Since rotary inertia moment of gear system in speed change stage is confined within a small range, speed change impact scarcely occurs even if return of the pressure plate 1d is reduced. Consequently, the time interval when power is not transmitted from a drive shaft 1a to an output shaft 3a can be shortened, and automatic speed change feeling for a driver can be improved.
Patent JP-H03250674-A (JP)
Title: Light emitting device
Inventor: TAKENAKA HIROSHI
IPC: H01S5/00
Filed: 1990-02-28
Abstract: PURPOSE:To monitor intensity of a light signal to be coupled to an optical fiber and intensity of reflected light simultaneously and independently by detecting the intensity of the light signal to be coupled from a light emitting element to the optical fiber by a first light receiving element and detecting the intensity of the reflected light from a transmission path on the side of the optical fiber by a second light receiving element. CONSTITUTION:When there is reflected light which has been generated in the way of a transmission path on the optical fiber 14 side to be incident on a light emitting element 12, this reflected light enters one of light waveguide paths 16 in a light splitter 15 from the optical fiber 14 and a part of the light is coupled to the other light waveguide path 17. The reflected light coupled to the light waveguide path 17 is impinged on a light receiving element 19, from which current proportional to intensity of the reflected light is output. The reflected light is hardly incident on a light receiving element 18 due to a directionality of the light splitter 15. Therefore not only the intensity of a light signal output from the light emitting element 12 but also the intensity of the reflected light from the transmission path on the optical fiber 14 side can be monitored simultaneously. Thus a transmission state can be stabilized by using the information thereby permitting a device failure to be found in an early stage.

Abstract: PROBLEM TO BE SOLVED: To permit a system to have structure where a malfunction owing to a clock skew does not easily occur by constituting a thinning device with a small circuit scale in a recognizing device where a thinning processing is executed in spite of difference in the resolution of an input image because of varying and the resolution of the picture to be recognized is made to be equal. SOLUTION: A thinning part is provided with a rough thinning part 10 executing thinning once in two times or thrice in the four times when a varying rate is more than 151% and a minute thinning part 12 permitting 75%-150% of the picture to be 75% (resolution is 300dpi). The minute thinning part executes thinning only when a thinning present signal is outputted based on a thinning original signal which is outputted from a prescribed n-notation thinning counter selected by the varying rate and a thinning mask signal which adopts the thinning original signal as the invalid one. The both signals are generated in a thinning condition deciding part 14 and an actual thinning processing is executed in a thinning processing part 16. A condition deciding part is constituted of the counter so as to be a small scale and resistible to the clock skew.
