IPC: F02D29/02
Filed: 1985-05-08
Abstract: PURPOSE:To make improvements in controllability and safety, by performing the follow-up control of a car only at a time when a switch is operated by a driver as he judges to be safe. CONSTITUTION:Those of car-to-car distance information and personal car speed information detected by a radar device 21 and a car speed sensor 23 are all fed to a signal processing circuit 25. A switch 31 being connected to this signal processing circuit 25 is being set to a state of being operatable when a stabilizing signal is inputted out of the signal processing circuit 25 at a driving safety state. Now, when this switch 31 is operated, the signal processing circuit 25 performs automatic follow-up control only at a time when this 'on' signal is detected. In consequence, when the stabilizing signal is not yet outputted, the switch 31 is no longer operated, whereby automatic follow-up speed adjusting control is made so as not to be done, and speed adjusting operation by judgment of a driver is made to have preference to others, thus safety is improvable.

IPC: G10D7/02
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To simply provide a high quality bamboo clarinet without very requiring skill and technique by reforming raw material of a prescribed size in a straight line, enclosing the lower part of the raw material, injecting mold material into it, inserting an unbalanced concaved surface type stem later and hollowing the inside out. SOLUTION: The raw material of the prescribed size is prepared to be reformed in a straight line, and the lower part of the raw material is enclosed, and first, the mold material is injected into it. Thereafter, the unbalanced concaved surface type stem is inserted softly into the mold material. After the mold material is hardened, when the stem is pulled out, the inside making of 99% of bamboo clarinet making work is ended, and thereafter, the work forming hand holes and the mouthpiece only remains. Particularly, when bamboo is the raw material, for making the most of the material quality of the bamboo material, the fact that the more the mold material is thin is good is above. Then, a central hole may be only the hole that the stem passes through.  Further, since the unbalanced concaved surface type stem is the same as the inside of so-called a famous bamboo clarinet, a high class bamboo clarinet, a tone, tone quality and the volume are remarkably excellent. Thus, difficult problems for making the bamboo clarinet are dissolved entirely to be mass produced.

Abstract: PURPOSE:To enable efficient and accurate focusing by making the position information obtained by position detection means and information analysis means set quantity of driving, by providing driving means of driving an object or a projection optical system along the optical axis and by setting optimum quantity of driving. CONSTITUTION:Nozzles 34-37 of four air microsensors attached to a reduced projection lens measure the distance to the surface of a wafer 4 and each measured value is calibrated to be made equal under the same conditions. At first, one of measured values of plural air sensors is taken in (S1) and the measured value is decided (S2) whether it is within a required tolerance or not, i.e., whether it is an abnormal value or not. I it is within the tolerance, the measured value is added in a memory and a counter for data acceptance is increased (S3). If it is out or the tolerance, the process of S3 is skipped. The same process is repeated (S4) for all the measured values of the air sensors in the same way. When the decisions of accepting all the measured values are finished, a mean value is obtained by dividing the total of added measured values with the number of acceptances and the mean value is made set quantity of driving (S5) and focusing is finished by the driving of a Z unit.
