Title: Synchronizer
Inventor: MIYA KAZUYUKI
IPC: H04J13/00
Filed: 1994-05-16
Abstract: PURPOSE:To obtain the synchronizer in which symbol synchronization is acquired with simple configuration in the spread spectrum multiple address communication using a spread code of a polyphase orthogonal series. CONSTITUTION:The synchronizer where correlation of transmission data subject to spread spectrum by a polyphase orthogonal series spread code is detected and symbol synchronization of transmission data is acquired based on a correlation detection output is provided with a low pass filter 2 receiving a correlation output of transmission data repeating the inversion and providing an output of envelope data, a zero cross point detection means 3 detecting a zero cross point of envelope data and a symbol timing generating means 4 outputting a symbol clock at a time elapsed by a time of a half of a symbol period from a time of the detected zero cross point. When a polyphase orthogonal series spread code is in use and the transmission data are inverted from +1 to -1, the sign of the envelope of the correlation output is inverted just in the middle of one symbol period. A point of time elapsed by a 1/2 symbol period from the zero cross point of the envelope is a symbol timing for symbol conversion.

CONSTITUTION:A conical rolling element 3, a small transmission wheel 6, a large transmission wheel 8, a bearing 13, and a pressure contact force generating device 11 to force the conical rolling element 3 into pressure contact with an output ring 4 are intercoupled through a sleeve 10, spline-engaged with an input shaft 1, to form a transmission assembly. a variation of the effective radius of the conical rolling element 3, i.e. a rolling contact position between a conical surface 5 and the output ring 4, and gear shifting are effected by movement of the transmission assembly over the axis of the input shaft 1 by means of a transmission control device 15 without being accompanied with movement of the output ring 4 coupled to an output shaft 2. This constitution relatively reduces control resistance produced when the transmission assembly is axially moved, and enables rationalization of manufacture of an R-type transmission through assembling.

Abstract: PURPOSE:To provide a system being possible to make a precise detection of the rate potential by means of resetting of a feedback circuit in a differential filter when the amplitude of the high frequency signal, corresponding to the last zone of QRS group or ST pattern which is indicative of the abnormality of heart, becomes larger than a prescribed value.

Title: High water repellent coated body
Inventor: KITAMURA MAKOTO
IPC: C23C14/12
Filed: 1993-05-27
Abstract: PURPOSE:To easily obtain the coated body having high water repellency without selecting the kind of a base material by applying fluororesin on the base material in a specified film thickness by vapor phase deposition method and allowing to present the graphite fluorine expressed by (CF)n in the film in specified condition. CONSTITUTION:In the coated body, a fluororesin layer is applied on the base material in >=500Angstrom  film thickness by the vapor phase deposition method. In the fluororesin layer, the powder of graphite fluoride expressed by (CF)n is allowed to contact with the material and at least some of the powders are exposed to the surface of the fluororesin layer. When the film thickness of the fluororesin layer is small, the fixing of the graphite fluoride powder is insufficient, so the film thickness is made to >=500Angstrom . In the production of the coated body, for example, the graphite fluoride powder is laminated on the base material, and the fluororesin is applied thereon by the vapor phase deposition method. In the method, since high temp. is unnecessary, even the base material low in heat resistance can be used.

Title: Gear
Inventor: BAN KOSHIN
IPC: F16H55/16
Filed: 1989-05-19
Abstract: PURPOSE:To enable the elimination of backlash at all times, and ensure the improvement of precision and the reduction of a vibration and a noise by forming the teeth of a gear with an elastic material, and a groove on each tooth from a both tip to at least a common pitch area including a radial plane equally dividing tooth thickness. CONSTITUTION:Gears 1 and 11 have each of teeth 1A, 1B and so forth, and 11A, 11B and so forth respectively made of a elastic material. In addition, the teeth have grooves 2 and 12. The teeth, therefore, is somewhat deformed when subjected to a load. Also, when the gears 1 and 11 are engaged with each other, backlash is not formed between the tooth surfaces of a pair of the engaged teeth 1A and 11A. Or rather, a slight load is applied between the tooth surfaces and the teeth 1A and 11A are so engaged with each other as to be slightly deformed. According to the aforesaid engagement, the teeth 1A, 1B and so forth, and 11A, 11B and so forth are elastically deformed, even if an error in the tooth shape and pitch of the gears 1 and 11, and the deflection or the like of teeth, shafts and bearings due to thermal expansion and load during operation take place. Consequently, the backlash can always be maintained at zero. According to the aforesaid construction, the precision of equipment can be improved and the vibration and noise levels thereof can be lowered.

Title: Semiconductor device

IPC: H01L29/78
Filed: 1985-06-12
Abstract: PURPOSE:To improve the density of mounting, by independently isolating the second region, in which an integrated circuit is formed, from the second region, in which a substrate and a vertical MOS transistor are formed. CONSTITUTION:An isolation part 6 comprises a p-type isolation region 49, which constitutes an isolating region formed in an N-type epitaxial layer on a p-type epitaxial layer 24. When the region 49 is grounded, the n-type epitaxial layer 7 in a vertical MOS transistor part 3 is electrically isolated from the epitaxial layer 7 in a CMOS circuit part 5. Therefore, the thickness of the n-type epitaxial layer, where the CMOS circuit part 5 is to be formed, can be made thick. The p-type epitaxial layer 24 and the isolation region 49 are formed so as to isolate a substrate 1, the vertical MOS transistor part 3 and the CMOS circuit part 5 independently. Therefore, the CMOS circuit can be formed in the n-type epitaxial layer having low impurity concentration. Thus,the impurity concentrations in regions 25, 27, 31, 33 and 35, which are formed in the layer 7 can be suppressed tot he low values. The threshold voltage can be also suppressed to the low value. Therefore, the characteristics such as the withstanding voltage and the threshold voltage can be freely determined.
