Title: Image pickup signal processing circuit
Inventor: FUKUDA TOKUYA
IPC: H04N9/07
Filed: 1987-12-28
Abstract: PURPOSE:To reduce the disposed number of a signal delay means having a delay time corresponding to the one horizontal direction read line term of an image pickup signal by matrix-processing a signal obtained from an image pickup signal synchronization processing part and conducting a luminance signal and a chrominance signal. CONSTITUTION:The image pickup signal sequentially obtained from a solid-state image pickup element 11 is supplied to an image pickup signal vertical processing part 21' including 1H delay means 22 and 23 and composed as for three horizontal direction read lines being continuous in a vertical direction on the image pickup surface part of the element 11. Next, a signal obtained from the processing part 21' is supplied to the image pickup signal synchromization processing parts 16a and 16b having the signal delay means in the sampling extraction of the image pickup signal. Thus, the 1H delay means 22 and 23 are used both as the correction of signal defect mixed to the image pickup signal obtained from the element 11 caused by a defect picture element on the image pickup surface part and the correction of an aperture for the conducted luminance signal. As the result of that, the disposed number of the 1H delay means can be effectively reduced.

Title: Substrate processing device
Inventor: NAKAJIMA YASUNORI
IPC: H01L21/027
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a substrate processing device in which an operator's manipulation is omitted when changing a mixing ratio between chemicals and pure water. SOLUTION: Before processing on an objective substrate is started, an operator inputs processing information (a processing period, the mixing ratio and the like) for the substrate from a keyboard 52. The input processing information is stored by a CPU 11 into a storage disk 13. Then, the CPU 11 transmits the processing information to a bath controller 20 when the processing on the substrate is started. A CPU 21 of the bath controller 20 stores the processing information into a memory 22. The CPU 21 transmits data indicative of the mixing ratio to a mixing unit controller 40. The mixing unit controller 40 automatically mixes the chemicals with the water based on the mixing ratio and sends the mixture to a processing bath. Thereafter, the substrate is conveyed to the processing bath, and the substrate is immersed into the bath for the predetermined period of time.

Title: Optical head using optical scanner
Inventor: KIN HIDEO
IPC: G11B7/09
Filed: 1990-11-29
Abstract: PURPOSE: To substantially decrease access time by correcting focusing and tracking direction errors due to an eccentricity of an optical disk by driving only a corrective optical system. CONSTITUTION: A laser beam emitted from a laser diode 1 passes through a focusing correction part, a corrective optical system 5, 6, 7, in order, and reaches a prism 8. This prism 8 makes a scan by the beam which has a different diameter ratio of the scanning direction to the rotational direction of the disk, and the beam is deflected by a mirror 9 and a rotary mirror 10, an optical scanning device, being reflected by a thick mirror 12, and the focus in the scanning direction is converged on a expected track on the optical disk 11, while the focus orthogonal to the scanning direction is converged on the optical disk 11 through cylindrical objective lens 13. In this case, the focusing correction is performed by driving cylindrical lenses 6 and 7.  Thus, since the whole optical head does not move but the optical scanning device operates scanning to seek a track by the beam, the accessing is accelerated.

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device, which comprises a process of forming the contact part of a field-effect transistor, prevents an overetching of diffused layers and element isolation insulating films and obtains good characteristics of the device. SOLUTION: Element isolation insulating films 5, a gate electrode 1, source and drain regions 4 and 4 and insulating films 3 on the sidewalls of the electrode 1 are formed, and thereafter, nitrogen is implanted in the entire surface of a silicon substrate 6, and an SiON layer 7 is formed on the upper parts only of the films 5 and the films 3 on the sidewalls. Then, after interlayer insulating films 8 are formed, contact holes 9 are formed. Etching of the films 8 for forming the holes 9 can suppress a short-circuit between the electrode 1 and the region 4 or between the region 4 and wells in the substrate 1, due to overething of diffused layers and the films 5 because even if the alignment of a contact exposure is deviated from an object, the upper parts of the films 5 and the insulating films 3 on the sidewalls are covered with the SiON film.

Abstract: PURPOSE:To provide the subject false twist yarn having a structure where a polyurethane as the core and a fiber-forming thermoplastic resin as the sheath are concentrically arranged, twisted in the longitudinal direction, having many levees on the surface, excellent in elastic recovery and bulkiness and useful for a textile structure, etc. CONSTITUTION:A polyurethane is produced by reacting a polycaprolactone glycol having 2000 molecular weight with p,p'-diphenylmethane diisocyanate and subsequently using 1,4-butanediol as a chainextender. The resultant polyurethane is used as the core and a fiber-forming thermoplastic polymer such as 12 nylon is used as the sheath. Conjugate spinning of both the components is carried out by melting the sheath component polymer by another extruder and discharging both the components through a sheath-core conjugate spinning nozzle having a concentrical circular shape. The spun yarn is then stretched by a factor of 2.5 times in the cold and subsequently subjected to false twisting by using a spindle-type apparatus, thus producing the objective polyurethane-based false twist yarn of a conjugated elastic filament composed of concentrically arranged core and sheath components, having S- or Z-direction twists within a range of 10 to 1000 time/m in the longitudinal direction and many levees on the surface of the filament.

IPC: B66B9/06
Filed: 1990-11-30
Abstract: PURPOSE:To decrease the number of plates installed and reduce the mounting works compared with conventional method, while the original function of fissure plate is maintained, by furnishing a detaining mechanism which is detained with a movable fissure plate in the condition that an elevator cage is situated in the inter-floor space and which moves the plate in a single piece with the cage. CONSTITUTION:When an elevator cage 14 begins moving between elevator halls 15, 15, a roller 52 of a lever 47 makes transmission to a pressing member 53 as a cam surface immediately after the cage 14 has separated elevator hall 15, and thereby the lever 47 rotates a detent member 46 in the direction of protruding to the movable fissure plate 33 side. Thus the detent member 46 advances against the resilience of a spring 51 to be fitted in a receptacle hole 42 in the plate 33. Therefore, the plate 33 moves between the halls 15, 15 in association with movement of the cage 14. According to this arrangement in which one plate each 33 moves between halls 15, 15 together with the cage 14, the spacing to the wall 30 of the pit can be held, which should secure the safety of crew and passengers owing to the plate 33 even in the event of door 23 opening in the inter-floor space.
