Title: Vibration eliminator for digital disk deck
Inventor: KURITA NAOSABUROU
IPC: G11B33/08
Filed: 1983-12-20
Abstract: PURPOSE:To eliminate a read error by applying the internal force to the gaps existing at the hook part, the coupling part and the rubbing part among component parts to eliminate those gaps. CONSTITUTION:A part A serving as a bearing part 23 of a feed motor 10 contains a spring 26 which has a contact with a roll 23b to give force to the roll 23 obliquely in the upper left direction. While a part of a bearing B has an angular bearing 27, and the component force of the spring 26 pushes the bearing 27. A roll 28 is energized toward a head 5 by a spring 29. A working point Pg has a vector of the force in the direction where the shaft of a gear system 13 increases the distance to the shaft of a gear system 14. While a working point Pe also has a vector of the force in the direction where the distance is increased between the system 13 and a rack 6. Then three guide rings 25 are provided to control the head surface, and a spring 30 and a roll 31 are used to energize the head 5 toward a disk 4. At a bearing rubbing part between the rotary shaft of a disk drive motor 2 and a turntable 3, rolls 20 and 21 energized by a spring 22 are pressed to a taper surface 19. In such constitution, the relative motions are never produced among component parts despite the application of impact or vibrations.

IPC: G02B26/12
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To eliminate the contamination of optical parts and a rotary polyhedral mirror by mounting a reflection mirror so as to seal the aperture of an optical box and providing the inside of the optical box with the glass surface of an incident light side in such a manner that the glass surface on an exit light side is exposed from the optical box. SOLUTION: Both ends in the longitudinal direction of the rear surface reflection mirror 71 are pressurized in the direction where these ends are butted against reflection mirror receiving parts 101, 102 on the optical box, by which the reflection mirror is held on the optical box. The surfaces exclusive of both ends are sealed by ribbed dustproof shapes 103, 104 formed at the optical box. Particularly the dustproof shape 103 is so disposed as to come into contact with the glass surface in the middle between the luminous flux incident part and exit part on the front side of the rear surface reflection mirror. The luminous flux deflected and reflected by the deflecting reflection surface 4a is made incident on the glass surface 71b on the front surface of the rear surface reflection mirror.  The light is thereafter reflected by the reflection film 71a of the rear surface reflection mirror and is emitted from the glass surface on the front surface of the position apart from the incident point. A photosensitive body is irradiated with the emitted light passing through the aperture of the optical box. The aperture on the scanning optical device is sealed by a cap 9 and the exit aperture to a photoreceptor by the rear surface reflection mirror 71.

Title: Device for compressing/extending time base of waveform signal
Inventor: KIKUMOTO TADAO
IPC: G10L21/043
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To control increase in waveform signal processing quantity accompanying increase in the number of dividing band and to build an inexpensive system by dividing a waveform signal to be compressed/extended on the time base into the main frequency band and independently compressing/extending the divided waveform signal of each frequency band. SOLUTION: The input signal x(n) being a waveform signal to be inputted, is inputted in the multi-rate pre-processor of a multi-rate analyzer. In the multi- rate pre-processor, a difference after subtracting the component of a low-order band in the input signal x(n) by a low-pass filter is made the component of the band O. Then, the main band is divided into four sub-bands, and the amplitude and the instantaneous frequency are analyzed. The waveform data of each sub-band so analyzed, being limited in the frequency band, greatly thins out the sampling period, compressing information quantity, and storing it in a storage part. As a result, it can control increase in the waveform signal processing quantity accompanying increase in the number of dividing band.

IPC: G03G15/02
Filed: 1987-09-25
Abstract: PURPOSE:To speedily detect the abnormality occurrence of the device by an easy method by providing a means which detects locking within a 1st time or nonlocking a 2nd time later from the last locking of a cleaning brush. CONSTITUTION:The brush 24 moves reciprocally between abutting plates 30 and 31 with a driving signal and a forward/backward rotation signal from a CPU to clean electrification electrodes 22 and 23. Here, the maximum value of the time required by the brush 24 to run between the abutting plates 30 and 31 is denoted as TMAX and the minimum value is denoted as TMIN. Then when a motor 29 is not locked, the elapsed time from the last locking is measured and when the time T is larger than TMAX, abnormality is judged to display the abnormality and stop the machine. When the motor is locked, on the other hand, abnormality is judged when the time T is smaller than TMIN, but when larger, the motor is reversed or the cleaning is finished. Consequently, the abnormality is detected easily and speedily.

Title: Method of sealing ic substrate
Inventor: HINO HIROHISA
IPC: H01L23/28
Filed: 1984-11-15
Abstract: PURPOSE:To prevent a rear-face electrode of an IC substrate from being covered with resin entering into through holes in the substrate, by closing up the entrances of the through holes on the surface of the substrate during the process of sealing the substrate with the resin. CONSTITUTION:A jig 9 is provided such that an IC substrate 1 having through holes 5 can be fixed thereon. Pins 10 having an approximately same diameter as the through holes 5 and the same height with the depth of the through holes 5 are mounted vertically on the jig 9 in the positions corresponding to the through holes in the substrate 1. The pins 10 are inserted into the through holes 5 so that resin is prevented from entering into the holes even if the viscosity of the resin is changed during the sealing with the resin 11. The holes 5 are thus closed up with the pins 10 until the resin is hardened. According to this method, the rear-face electrode of the substrate 1 is not covered with the resin and therefore no defect in continuity is produced.

Abstract: PROBLEM TO BE SOLVED: To secure light weight, favorable stepping feel, and reasonable cushioning performance by specifying a rate of gaps between inner fibers in the whole volume, and laminating a surface layer of resin composition with the surface of a thick cloth of a constant thickness. SOLUTION: Fibers 18, 20, 22, 23, 26 of a thick cloth in which a volume ratio of gaps between the fibers is 30% or more are used as the main material, and a surface layer 14 of resin composition is laminated on the surface of a thickness of 2 mm or more. In this case, mineral grains of 0.3-2 mm are dispersed in the liquid resin composition, and it is applied on the thick cloth or a resin-coated base cloth. A thickness of a double warp fabric 27 from an upper cloth 21 to a lower cloth 25 is 2-5 mm, and the base warp yarn 18, 22, 23, insertion yarn 20, and connection yarn 26 are monofilament yarns of 30 denier or more. Thinness and light weight can be achieved compared to conventional devices, and the fibers of a fiber web are pressed and bent in a thickness direction by needle punching to be continuous from the surface side to the back side to be difficult to be removed.  Floating and sinking of the surface by foot pressure given by walking can thus be reduced, thereby fatigue feel of a walker can be prevented.
