Title: Optical disc
Inventor: KYODA TAKESHI
IPC: G11B17/043
Filed: 1995-06-28
Abstract: PURPOSE: To prevent the other face of a hub from tightly adhering to a cartridge, insert a clamp pin normally into the hub and eliminate chucking failures in an optical disc, by providing a projection of a specific roughness oat a face of the cartridge facing the other face of the hub outside the hub. CONSTITUTION: A cartridge 7 is integrally formed out of a polycarbonate resin. A circumferential projection 8 of a height of (x) and a radius of 12-14mm is formed on a face of the cartridge 7a outside the hub and confronting the other face 4b of the hub 4 among cartridges 7a and 7b. This height (x) (0.6mm) of the projection 8 is larger than the distance (y) between the other face 4b of the hub 4 and the face of a disc-like body 2. The surface roughness of a face E (having a radius of 11-16mm) confronting the projection 8 on the other face 4b of the disc-like body 2 is 5-35μm. If the roughness is 35μm or larger, static coefficient of friction is increased, thereby, chucking failures or friction dust are apt to be generated.

Title: Formation of filter layer in spinneret pack
Inventor: TOKIYAMA YASUHIRO
IPC: D01D1/10
Filed: 1978-12-26
Abstract: PURPOSE: To form filter layers of large, mixed, and small grain sizes in order from before the pack, and to filter the molten polymer uniformly with a high accuracy, by vibrating a mixture of two types of filter media having different grain sizes filled in the pack.  
     CONSTITUTION: A mixture of two types of filter media having different grain sizes are filled in a spinneret pack, and vibrated. Thus, grains of small size separate and migrate to the underlayer to form the middle layer of mixed grain sizes, on which the upper layer of only large size is formed with a high operating officiency. The media previously vibrated will not easily cause turbulence in the layers. Improved filtration and kneading accuracy, product quality, and yield are obtained.

Abstract: PURPOSE:To obtain a substrate having an InP epitaxial layer of high resistivity on the surface by epitaxially growing an undoped n-type InP layer on the surface of the substrate, then heat treating the substrate under a phosphorus vapor pressure. CONSTITUTION:The InP epitaxial layer is grown about 2 microns without adding an impurity by a chloride vapor growth method, etc., on the semi-insulating InP single crystal substrate which is doped with Fe to a specified quantity (0.2ppmw) or above by using a horizontal type vapor growth device of a hot wall type, etc. This substrate is set together with red phosphorus into a quartz ampoule and after the ampoule is evacuated to 1X10<16>Torr, an aperture is sealed by an oxyhydrogen burner. The quantity of the red phosphorus is so adjusted that the phosphorus vapor pressure as P4 in the ampoule attains >=6kg/cm<2> (absolute pressure) at this time. This ampoule is then installed into a horizontal type heating furnace and is heated and held for about 20 hours at about 900 deg.C heat treating temp. and thereafter, the ampoule is cooled. The semi-insulating InP grown layer having >=1X10<7>OMEGA.cm resistivity at 300K is thus obtd.

Filed: 1985-07-24
Abstract: PURPOSE:To recover an abnormal end to continue a program by producing a load module so as to execute again a module having the same function and stored in another library in case an instruction is received to give an abnormal end to the program. CONSTITUTION:A linker 3 detects a CALL-ABORT instruction out of a loaded library 1 and loads a module 201 having the same function as a module 502 including the CALL-ABORT instruction through another library 2. Then this instruction is replaced with a branch instruction to the entrance address of a module 503 loaded later. Thus a load module is produced so as to execute again the module having the same function and stored in another library in case an instruction is received to give an abnormal end to a program. Therefore a module can be executed again before revision when the program has an abnormal end state owing to the bug mixed by the revision in case the libraries 1 and 2 are defines as those set after and before revision of the program respectively.

Abstract: PURPOSE:To obtain a rice transplanter, capable or maintaining the control reference value in lifting and lowering control constant and performing the control with a high precision without regard to the regulation of planting depth. CONSTITUTION:A travel machine body is connected to a seedling planter with a hydraulic cylinder (CY) for lifting and lowering (actuator) so as to freely drive, lift and lower the seedling planter. The rear side of a land grading float 3 is pivoted on the tip of a supporting arm 43 so as to enable free vertical rocking relatively to a frame 7 of the seedling planter and the supporting arm 43 is constructed so as to make free vertical regulation and fixation of the position with an operating lever 39. Thereby, the planting depth can be changed. Furthermore, the actuator (CY) is driven and controlled based on sensed results of a potentiometer (PM) for sensing the vertical travel following the fluctuation in ground contact pressure on the front side of the land grading float 3 so as to maintain the ground posture of the seedling planter in a prescribed state. A sensing action part 52 of the potentiometer (PM) is supported through a parallel quadric link mechanism 46 relatively to the frame 7. As a result, the sensing action part 52 is constructed so as to vertically move interlocking with the vertical movement in a fulcral part of the land grading float 3 following the operation of the operating lever 39.
