Title: Production of magnetooptic recording medium
Inventor: TAKAYAMA SHINJI
IPC: G11B5/852
Filed: 1985-03-15
Abstract: PURPOSE:To prevent the deterioration in the characteristic by a heat treatment of a recording film and to improve the characteristics and life of the recording film by subjecting the amorphous film to a heat treatment while applying an external magnetic field thereto in the direction perpendicular to the film plane. CONSTITUTION:An SiO2 film, recording film and SiO2 film are deposited on a high-molecular substrate consisting of glass or epoxy polycarbonate, etc. having guide grooves to preparean optomagnetic disk.

Title: Speech recording medium
Inventor: SUGAWARA NAOTO
IPC: G11B3/68
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to output speech language recognized as various languages by tape-form or sheet-form speech recording medium, by utilizing stripping sound having different frequencies generated by mutual self- adhesiveness, thickness of stripped-off material, adhesive face area, etc., at a time of stripping off mutually adhered materials with a self-adhesive agent. SOLUTION: A sheet 11 and a cover 14 are adhered to each other with plural self-adhesive agents having mutually different viscorsities and areas. And, when the cover 14 is stripped off from the sheet 11, synthesized stripping-off sound peculiar to each self-adhesive agent is made as a speech language. Further, for a complex high frequency output forming a consonant, projecting and recessing part 15 is formed mosaically.  Further, a sound source of the speech language is mechanical vibration of the cover 14 generated when the sheet 11 and the cover are stripped off from each other, and since the cover 14 resonates itself to generate the stripping-off sound, if the cover 14 is provided with the projecting and recessing parts 16a-16d for adjusting a sound volume according to fortmant sound pressure, stripping-off sound similar to a speech language is generated and it becomes easy to recognize as a speech language.

Title: Method for sheeting perforated steel plate
Inventor: IDATE HIDENORI
IPC: B29C48/305
Filed: 1980-04-15
Abstract: PURPOSE:To prepare a resin coated perforated plate having a resin coating of which a surface is smooth by subjecting the perforated plate to the extrusion coating by using an extruder having a long die lip and a large volume resin sump for keeping a resin pressure to a definite level or less. CONSTITUTION:A length of the die lip L is set to a dimension sufficiently longer than a diameter of a hole 2 of the perforated plate 1 and the large volume resin sump 5 is formed to surfaces 3a, 4a of a metal mold and, in this condition, a molten resin 9 is sent into the resin sump 5 from the extruder through a manifold 6 and a restrictor 7 equalizing a resin stream. The resin is coated on a surface of the perforated plate 1 while a transfer speed of said perforated plate and an emitting amount of the resin are controlled so as to keep a resin pressure to a definite value or less. Becasue the die lip L is long, the resin filled in the hole 2 is solidified in an apparatus and prevented from being flowed downwardly. Because the resin is coated under a definite pressure or less, the resin in the hole 2 is not expanded after coating and a surface thereof is made smooth.

Title: Proximity fuse
Inventor: YAMANE HIDEO
IPC: G01S7/36
Filed: 1988-03-04
Abstract: PURPOSE:To prevent malfunction which is caused by an external disturbing wave and to optimize an initiating operation period by imposing frequency modulation on a signal to be sent, and passing a received signal through a matched filter suitable to the frequency modulation. CONSTITUTION:A reference signal generator 13 generates a reference signal with an intermediate frequency (IF) band. The matched filter 20 has characteristics adapted to the frequency modulation and performs the pulse width compression of the output signal of an amplifier 17. Then the pulse widths of signals detected by detectors 18 and 21 are prescribed pulse widths respectively and pulse width discriminators 19 and 20 output prescribed signals only when the amplitudes exceed a prescribed level. A gate circuit 23 passes the output signal of the discriminator 20 only when there is the output signal of the discriminator 19. A Doppler detector 24 inputs the output signals of the generator 13 and discriminator 20 to detect a Doppler signal corresponding to the relative speed between a guided airframe and a target plane. A counting circuit 25 counts the output signal of the circuit 23 and operates an initiation circuit when the counted value exceeds a threshold value which varies with the Doppler frequency outputted by the detector 24.

Title: Apparatus for adjusting elongation force of recording sheet
Inventor: MITSUISHI TSUTOMU
IPC: B41J15/16
Filed: 1988-03-04
Abstract: PURPOSE:To prevent the generation of wrinkles in a recording sheet and to make the recording sheet easy to feed, by a method wherein a tension roller on a supply side is rotated so that the centrifugal force of the protruding part of the tension roller on the supply side goes to the direction opposite to the feed direction of the recording sheet and a tension roller on a take-up side is rotated at a speed faster than that of a platen. CONSTITUTION:The centrifugal force of the protruding part 7a1 of the first tension roller 7a goes to the direction opposite to a feed direction by the rotation of said roller 7a. Back tension F is generated in the part of the ink sheet 3 brought into contact with the roller 7a so as to be turned to the end parts of said sheet 3 in the lateral direction thereof and component forces F1, F2 act to make it possible to also draw out the part on a supply side in the outside direction of the sheet. By this drawing-out, no undulation or bending is generated in the sheet 3 and wrinkles are not also generated in said sheet 3. Further, since the rotational speed of the second tension roller 7b is faster than that of the platen 1 and the component forces F1, F2 act on the ink sheet 3 by a front tension P, the back tension F can be kept almost constant.

Filed: 1990-03-02
Abstract: PURPOSE:To surely detect the state of eyes and the direction of faces of lots of unspecified drivers at a high speed by using a neural network receiving a face part picture information and outputting an input weight sum so as to detect the state of eyes and the direction of faces of automobile drivers. CONSTITUTION:The above monitor consists of a TV camera 10, a binarizing circuit 12, a segmentation circuit 14, a neural network 16, an ECU 18, an arithmetic unit 24 and a neural network 26.

Thus occurrence of inattentive drive or driving asleep is detected depending on the state of eyes and the direction of faces of the drivers and effective information for safe drive is obtained.
