Title: Developer for positive type photoresist
Inventor: KANAZAWA MASAO
IPC: G03F7/30
Filed: 1980-05-20
Abstract: PURPOSE:To eliminate conventional dummy development repeated several times in the early stage in case of a fresh developer and to easily realize a continuously developing system by dissolving a small amount of resin as the base material of a positive type photoresist in a developer for the photoresist. CONSTITUTION:When a positive type photoresist prepared by dissolving o-naphthoquinone diazide as a photosensitive substance in novolak type phenolic resin as a base material is developed with N(CH3)4OH as a developer to dissolve and remove the exposed part, 0.1-0.2g/l novolak type resin is dissolved in the developer. Conventionally, such a photoresist is developed at low speed several times in the early stage, and product wafers are lost by the dummy development. Using the resulting developer said defect is eliminated, a dropping type continuously developing system is easily realized, and development can be repeated about 100 times.

Filed: 1978-06-02
Abstract: PURPOSE:To produce an element, which has a low loss which can be easily produced, by combining lenses such that the light for bidirectionally transmitting through an optical fiber can be partially extracted. CONSTITUTION:A lens 15 is arranged such that its center axis 15c lies on the extension of the polished joint sides of lenses 16 and 17 of square refractive index distribution type. The light emanating from an optical fiber 11 is substantially collimated by the lens 15 and divided into halves, which are then introduced into the lenses 16 and 17, respectively. The light having entered the lens 17 is focused as an image having the same size as the core of the fiber 11 upon the center axis of the emanaging side. On the other hand, the light having entered the lens 16 is reflected with respect to the center axis 16c so that an image having the same size as that of the core of the fiber 11 upon the center axis 18c of the emanating side of a lens 18 and is transmitted to an optical fiber 12. The light from the fiber 12 is also divided into halves which are transmitted to fibers 11 and 14.

Title: Hydraulic controller for v-belt type continuously variable transmission for vehicle
Inventor: MIKI NOBUAKI
IPC: B60W10/101
Filed: 1987-03-24
Abstract: PURPOSE:To stabilize line pressure during stoppage by providing a means for lowering the line pressure for a first hydraulic servo when a throttle opening is smaller than a predetermined level and the torque ratio between input and output shafts of pulley is higher than a predetermined level. CONSTITUTION:When a torque ratio is higher than a predetermined level, an oil path 9 is discharged through a drain port 666, but a port 663 is opened to communicate between oil paths 1, 6. Consequently, when the throttle opening is within a low range and a spool 641 of a detent valve 64 is at the left side, the oil path 6 is closed and the oil path 7 is discharged through an oil path 5 from a manual valve 62. When the throttle opening is within a high range, the spool 641 moves to produce detent pressure in the oil path 7. Consequently, the line pressure changes in step in a range where the throttle opening is low. Since the line pressure for a high range torque ratio is lowered within a low throttle opening range, the line pressure is stabilized during stoppage or faint motion.

Further, at the end of a call, if a forced-cut due to absence of coin takes place, a signal outside of band is transmitted from a terminal telephone set, and when this signal is received and detected at a receiver 3h, a relay LOT3i is operated and the contact 3j is connected to a +BB power supply to activate an MP relay. Through the operation of the MP relay, the addition to the call meter by +1 at the end of call is not made by cut-off.

Title: Core tube for drawing optical fiber
Inventor: FUJIMAKI MUNEHISA
IPC: C03B37/029
Filed: 1993-03-26
Abstract: PURPOSE:To provide the subject core tube designed to cut electric power consumption by matching the direction of higher thermal conductivity for anisotropic carbon with the radial direction of the core tube. CONSTITUTION:Using anisotropic carbon as the material for a core tube 6, the direction of higher thermal conductivity for the anisotropic carbon is matched with the radial direction of the core tube 6, and the direction of lower thermal conductivity with the longer direction of the core tube. Thereby, the propagation of radiation heat from a heater 2 is reduced in the direction of the core tube 6, maintaining the temperature of the core tube 6 near the molten portion 4a of an optical fiber matrix 4 where the heater 2 is placed at an elevated level; thus the matrix 4 melts effectively along with reducing both the range and quantity of particles produced, affording the aimed optical fiber 5 of high mechanical strength.

Abstract: PURPOSE:To extend a crosswise solid phase epitaxial growth distance and then form an SOI film having a large area by forming a single crystal silicon film on a seed part which is formed by a selective epitaxial growth process and forming a polycrystal silicon film on an amorphous insulating film. CONSTITUTION:After forming an amorphous insulating film 10 on a single crystal silicon substrate 9, exposed faces 11 are formed on the substrate by removing parts of the insulating film 10 and seed parts 12 of single crystal silicon are formed by a selective epitaxial growth process on the exposed faces 11. Then single silicon films 14 as well as a polycrystal silicon film 15 are formed respectively on the seed parts 12 and insulating film 10. Ion implantation of silicon into surfaces of these films makes surface layer parts of the single silicon films 14 and the whole part of the polycrystal silicon film 15 amorphous and then an amorphous silicon layer 16 is formed. After injecting phosphorus into the amorphous silicon layer 16, its single crystallization is obtained by a solid phase epitaxial growth process. A crosswise solid phase epitaxial growth distance is thus extended and an SOI film having a large area is obtained.

Abstract: PURPOSE:To enhance the vibration-suppressing function of a truss by a method in which the bar part of truss is cut off to form an aperture between the cut ends, a visco-elastic layer is formed on the periphery of at least one end, and a restrainer consisting of a pair of halved tubes is set between both ends and fixed from the circumferential direction.

A uniform layer 7 of a visco-elastic material 6 is formed on the periphery of at least one end, and restrainers 8 and 9 consisting of a pair of halved tubes are provided to both ends facing each other to pressingly fix them from the circumferential direction. Since the uniformity of bonding between the part 2 and the material 6 and between the material 6 and the restrainers 8 and 9 can be secured, the vibration energy of the truss 1 can thus be exactly converted into heat energy by the shearing deformation of the material 6 to obtain high vibration-suppressing function.
