Title: Flame-retardant composite nonwoven fabric and its production
Inventor: NOGUCHI NOBUO
IPC: D04H5/03
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain a composite nonwoven fabric having both tenacity in the machine direction and flame retardance. SOLUTION: This composite nonwoven fabric is obtained by laminating a staple nonwoven fabric having flame retardance to at least one side of a filament nonwoven fabric composed of a polyester polymer containing >=500 ppm phosphorus atom. The filament nonwoven fabric has a great number of partial heat contact bonding regions and a constituent filament is substantially oriented in the length direction in a not partially heat contact bonding region. The staple nonwoven fabric retains a shape by mutual interlacing of a constituent staple. The filament and the staple are mutually interlaced and integrated as a whole on the laminated faces of the filament nonwoven fabric and the staple nonwoven fabric.

Title: Structural body of rotary head and vtr
Inventor: WASAI KIYOTAKA
IPC: G11B5/024
Filed: 1987-09-02
Abstract: PURPOSE:To improve the effective utilization rate of a magnetic tape area and to prolong the recording time of the tape by controlling a distributor by timing pulses to distribute and transmit erasing signals successively and properly to respective erasing heads so that recording patterns are erased successively discretely at equal intervals. CONSTITUTION:The magnetic recording patterns mounted with 4 pieces of the erasing heads 4 can be successively recorded at equal intervals by each of the respective recording heads at the time when the recording heads 2 magnetize the magnetic tape successively by the recording signals fed respectively independently via a rotary transformer 9. Respective playback heads 3 trace on the tracks magnetized by the heads 2 and take out reproduction signals which are sent via an amplifier 27 to the rotary transformer 9. The erasing head 4 travel on the tape patterns in precedence to the recording heads 2 and, therefore, the heads 4 travel while erasing the tracks of the previously recorded tape patterns and thereafter, the recording heads 2 make recording successively. The unrecorded parts are thereby diminished, by which the effective utilization rate of the magnetic tape area is improved and the recording time of the tape is prolonged.

IPC: H01L21/225
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To prevent crystal lattice defects from occurring due to epitaxial growth by growing an insulation film where a semiconductor substrate is exposed and setting the thickness of amorphous layer formed by ion implantation to a specific value or less of the thickness when there is no insulating film. SOLUTION: A mask 12 is formed on the impurity non-diffused region of a semiconductor substrate 11 via an insulating film 12. In the process for growing an insulation film, the insulation film 12 where the semiconductor substrate 11 is exposed is grown and the thickness of amorous layer 15 formed by ion implantation is set to 20% or less when there is not insulation film 12. Further, ions are implanted from the semiconductor substrate 11 and the amorphous layer 15 is formed on the surface of the impurity diffused region of the semiconductor substrate 11. Then, the semiconductor substrate 11 is subjected to heat treatment and the amorphous layer 15 is crystallized.  At this time, since no [111] face appears on the amorphous layer 15, only epitaxial growth occurs in [100] orientation and a high-concentration impurity diffused layer 16 without any crystal lattice defect is formed at an edge part.

Title: Formation of polarization inversion grating and optical waveguide
Inventor: MAKIO SATOSHI
IPC: G02F1/37
Filed: 1993-08-10
Abstract: PURPOSE:To generate SHG light with high efficiency by realizing the ideal polarization inversion grating of a rectangular shape. CONSTITUTION:A proton exchange region 16, the polarization inversion grating 12 extending outside this region and an optical waveguide 13 are simultaneously formed by a proton exchange treatment on an LiTaO3 substrate 11. A grating pattern mask is first formed on the front surface of this substrate and a metallic film over the entire rear surface thereof. The substrate is subjected to the proton exchange treatment at >=50 deg.C/min temp. gradient at the time of the treatment and >=50 deg.C/min temp. falling speed from the treatment temp. to form the proton exchange region 16 and the polarization inversion grating 12 extending outside this region. A substrate holder of this time is electrically grounded. The refractive index of the proton exchange region 16 is thereafter increased by the heat treatment. The optical waveguide 13 is thus easily realized by one time of photolithography and the SHG element having the high efficiency is realized.

Title: Motor drive circuit
Inventor: YOSHITOMI TETSUYA
IPC: H02P6/08
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To suppress vibration noise of a motor while preventing the drive efficiency from lowering. SOLUTION: A select circuit 42 selects either of voltages V2 or V4, depending on the ambient temperature variation. When the voltage V2 is higher than the voltage V4, the select circuit 42 selects and outputs the voltage V2. A comparator 17 thereby compares a sawtooth signal C with a reference voltage V2. When the ambient temperature rises and the voltage V2 drops below the voltage V4, the select circuit 42 selects and outputs the voltage V4. The comparator 17 thereby compares the sawtooth signal C with a reference voltage V4. The reference voltage V4 limits the contraction width of a first comparison signal D to an interval T3 and since the end and the start of drive currents IL1, IL2 can be prevented from overlapping, the drive efficiency of motor can be prevented from lowering.

Filed: 1986-09-17
Abstract: PURPOSE:To enable a master of one of two systems to give a direct access to a slave of the other system and to increase the processing speed, by providing a gateway mechanism between two pairs of systems consisting of master and slaves. CONSTITUTION:When a flip-flop 4 is set by a signal 'b' received from a master B, a gateway using request B signal is delivered. In this case, a flip-flop 3 is set by the output of an AND gate 8 as long as the flip-flop 3 is kept reset. Then a gateway using permission B signal is delivered and the master B can give an access to a slave A. Then a flip-flop 6 is reset in accordance with a resetting action of the flip-flop 4. Thus the gateway using permission B signal disappears. A master A gives an access to a slave B in the same way.

IPC: D04H3/16
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle die in which the nozzle hole plate has vertical grooves bored on both faces in a zigzag arrangement independently from one another. SOLUTION: A nozzle hole plate is set between a pair of nozzle blocks to form a group of nozzle holes, while pressurized air holes are formed between the nozzle block and the air block. The air sprayed from the pressurized air holes are allowed to collide to the thermally melted resin extruded out of individual nozzles in the nozzle hole group to stretch the line screen of the resin to fibers with the airsucking effect of the sprayed air. In this case, vertical grooves are formed on both surface of the nozzle hole plate independently from one other in a zigzag arrangement in the cross section view thereby constituting nozzle hole groups that are arranged in zigzag and independent from one another.  In the front view of the nozzle hole plate, the nozzle holes on the back face side are positioned between the nozzle holes on the front face side and the number of melt-extruded polymer lines is doubled and the interval between these polymer lines are narrowed almost half and dense fiber board can be obtained.
