Patent JP-H03211516-A (JP)
Title: Automatic focusing device
Inventor: AKASHI AKIRA
IPC: G03B13/36
Filed: 1990-01-16
Abstract: PURPOSE:To suppress the defective operation of lens driving by previously storing the past focus detectability and non-detectability in each of plural subject regions and forcibly handling the detectability as the non-detectability even if the region becomes detachable again after the region is once non-detectable. CONSTITUTION:If the subject region is once detectable in focus in the past, the operation is shifted to the next and the failure in detection after this region is once detectable is stored. Whether the region is nondetectable or not while the focus thereof is once detectable is decided. The operation is shifted to the next if the result is yes. The region 1 which is detectable this time is handled as the focus non-detectability. The past focus detectability and non-detectability are kept stored in such a manner and the region is handled forcibly as the non-detectability even if the region becomes focus detectable again in case the region is non-detectable after the region is once detectable. The defective operation of the photographic lens driving by the repetition of the focus detectability and non-detectability is thus suppressed.

Title: Miniature drill
Inventor: YAMAZAKI SHINSUKE
IPC: B23B51/00
Filed: 1988-01-18
Abstract: PURPOSE:To eliminate resin-pluck at the starting time of a process so as to aim at improvement of manufacturing yield by forming at least the cutting edge at an outer circumference by a honing edge in cutting edges formed at the top end portion of a drill body and the outer circumference. CONSTITUTION:The top end of a drill body 1 is formed like a column the outer diameter of which is about several hundreds mum - several mm of predetermined diameter. Cutting edges 4, 5 are treated by a honing process at respective top end portion to become honing edges. Accordingly, since the honing process is treated at the tops of cutting edges 4, 5, at an early stage for starting the process like a conventional one, resin plucks are not generated at the inner wall of the hole by a sharp cutting edge not to cause the change for the worse of face roughness so that superior face-roughness accuracy can be obtain from the beginning of the process.

IPC: H04R25/02
Filed: 1992-01-21
Abstract: PURPOSE:To provide a hearing aid which enables a user to satisfactorily hear a voice without paying his attention to the adjustment by changing the signal processing characteristic of the hearing aid in accordance with the acoustic signal inputted to the hearing aid. CONSTITUTION:In this hearing aid, the inputted audio signal is divided into four channels, and the frequency band of each channel is divided into bands having meanings respectively. For example, vowels and consonants mainly pass in the band which passes through a band-pass filter 24. Plosive consonants and vowels mainly pass in the band which passes through a band-pass filter 25. Fricative consonants are emphasized in the band which passes through a band-pass filter 26. A band-pass filter 27 allows sounds other than voice to pass through. Thus, the acoustic signal of high articulation is given to a person, who is hard of hearing, by emphasis of consonant sounds or the like.
