Patent JP-H0311635-A (JP)
Title: Manufacture of compound semiconductor device
Inventor: TANAKA YASUHIRO
IPC: H01L21/314
Filed: 1989-06-08
Abstract: PURPOSE:To form a MIS type element or the like whose electric characteristic is good and whose change with the elapse of time is not caused by a method wherein, after a first insulating film has been formed on the surface of a substrate at a specific substrate temperature, a heat treatment is executed at a temperature higher than that temperature and a second insulating film whose composition is the same as that of the first insulating film is formed. CONSTITUTION:A compound semiconductor substrate 1 is cleaned; after that, a first insulating film 2 is formed at a low temperature of less than 100 deg.C by using a microwave plasma CVD method or the like without disturbing a very thin spontaneous oxide film on the surface of the substrate 1. Then, a defect which is unavoidable even by forming the first oxide film 2 at the low temperature of less than 100 deg.C and which is caused at the spontaneous oxide film is restored by a heat treatment at a temperature of 100 deg.C or higher. Then, a third insulating film 3 whose composition is the same as that of the first insulating film 2 is formed to be dense by raising a temperature at a film formation operation to 100 deg.C or higher. An influence from the outside on a semiconductor interface is prevented by this second dense insulating film 3. Thereby, it is possible to form a MIS(metal insulator semiconductor) type element or the like whose electric characteristic is good, whose change with the elaps of time is not caused and which is stable.

Title: Pattern generation circuit
Inventor: KAWARASAKI FUTOSHI
IPC: G11C29/10
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a pattern generation circuit that can properly convert data where an address does not agree in a phase to physical data. SOLUTION: A sequence control part 1 outputs address and data pattern generation instructions according to a program. An address pattern generation part 2 generates an address pattern based on the address pattern generation instruction, and a data pattern generation part 3 generates a data pattern based on the data pattern generation instruction. An address storage part 4 stores an address to be outputted form the address pattern generation part 2, and at the same time successively outputs the address corresponding to data to be outputted from the data pattern generation part 3. A data scramble part 5 converts the data being outputted from the data pattern generation part 3 to physical data based on the address outputted from the address storage part 4. A phase adjustment part 6 adjusts the phase of the address for the physical data for outputting.

Title: Manufacture of air spring sleeve
Inventor: OONISHI OSAMU
IPC: B29B15/00
Filed: 1981-09-12
Abstract: PURPOSE:To obtain an air spring sleeve having excellent long durability by longitudinally inserting a green molding die formed of a seamless rubber tube into a mold having no split surface, followed by vulcanizing and molding it. CONSTITUTION:A seamless rubber tube 13 extruded in advance in a cylindrical shape with a length twice of the prescribed length is inserted into a core die 11, and a layer of a rubber-coated tire-fabric cord reinforced layer 14 is wounded on the die. Then, a bead 15 is wound fixedly at a position corresponding to a groove 12 formed at the center of the die 11 on the layer 14. Subsequently, when an ultrafine amount of air is blown from an air diffuser 16 provided in advance at the die 11 and is moved to the left half side while expanding the part of the right half side 11a from the bead 15, it is inverted at the bead 15 as the boundary. One half of the tube 13 becomes a coated rubber by this inversion, and the reinforced layer becomes two layers. Since the part, to which the bead 15 is inserted, becomes unnecessary after this inversion, it is cut peripherally on the die 11, thereby pulling out the green molding die having the prescribed length from the die 11.

IPC: B41F31/08
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To eliminate a flow of ink from an ink supply unit to upstream side of an ink conveying roller at the time of non-printing. SOLUTION: An ink supply pine 26 for supplying an ink is disposed near a surface of an ink conveying roller 18 in a plate cylinder 10. The pipe 26 dams up the ink by suitably selecting a gap L2 between the roller 18 and the pipe 26. That is, if the gap L2 is set narrowly, the ink is prevented from being flowed upstream of the conveying direction by viscosity of the ink itself.

Title: Light-emitting element and its manufacture
Inventor: SASAKI HIRONORI
IPC: G02B5/18
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting diode the extracted luminous energy of which can be increased, without reducing the minimum line widths of computer holograms. SOLUTION: A light-emitting diode 20 has such a distinctive feature that its light-emitting center is positioned in a substrate and a plurality of computer holograms CGH21, CGH22, and CGH23 are formed on the light-extracting surface of the substrate. When the diode 20 is constituted in such a way, the control of lens layers is facilitated, because the minimum line width of each lens layer can be increased as compared with the case where collimation is made by using one computer hologram by gradually deflecting light by successively passing the light through the computer holograms CGH21, CGH22, and CGH23. Therefore, the light quantity luminous energy extraction efficiency of the diode 20 can be improved.

Title: Prevention and control of vibration
Inventor: NAKAMURA YUJI
IPC: H02P29/00
Filed: 1986-06-19
Abstract: PURPOSE:To suppress an influence to the load of a detrimental torque ripple generated in a reduction gear by adding a correction signal for cancelling a vibrating force generated from the gear to a command value. CONSTITUTION:A band pass filter 9 obtains the vibration component of a speed or an acceleration with the frequency band of a torque ripple generated in a harmonic driver as a passing band. A calculator 10 calculates a correction signal for suppressing the vibration of a load due to a vibrating force generated in a reduction gear on the basis of the vibration component theta3 and the speed command value omegar of a motor. This correction signal is added to the torque command value taur. Accordingly, the influence of a detrimental torque ripple generated in the gear to the load is largely suppressed, thereby providing high accuracy and high acceleration of a motor-driven machine having the reduction gear.

Abstract: PURPOSE:To provide automatically an optional quantity of spaces to recording paper easily by providing a space control circuit shifting the start timing of an optical unit base start signal and a head start support start signal. CONSTITUTION:When a left page start switch 100 is set and a copy start switch 91 is depressed, an output Q of a FF 102, i.e., a high level is fed to a control terminal 111 of a changeover switch 106. In this case, a polarity inversion circuit 98 connects an output of a delay circuit 93 to an output terminal 109 via an input terminal 107 and connects a reference signal to an output terminal 110 via an input terminal 108. Since the terminal 109 is used for an optical base unit base start signal and the terminal 110 is used for a head support start signal, the head support is started earlier than the optical unit base in this case and a space is caused at the left end of the recording paper. The operation is reversed when a right page start switch 101 is depressed.
