Title: Production of base material for optical fiber
Inventor: ITO YOSHITAKA
IPC: C03B8/02
Filed: 1985-10-25
Abstract: PURPOSE:To inexpensively obtain a base material for an optical fiber having high accuracy with a simple device by putting a fluid raw material which can be solidified and liquid material which has the specific gravity larger than the specific gravity of the fluid raw material into a tubular rotating body and solidifying the fluid raw material while rotating said body. CONSTITUTION:The fluid raw material 7 which is a sol, etc. consisting of a metallic alkoxide and pulverized silica particles and can be solidified and the liquid material 6 which has the specific gravity larger than the specific gravity of the material 7 and does not dissolve with the material 7 or has the small solubility with each other are put into the tubular rotating body 5. The body 5 is then attached to a rotating device and while said body is rotated at the number of revolutions at which the centrifugal force by the rotation exerted to the material 7 attains >=1G (G is gravity acceleration), the material 7 is fixed. The base material for the optical fiber having specular surfaces on both the inside and outside surfaces and having high accuracy is thus obtd. A thermoplastic resin, dichloroethane, etc., are adequately used for the material 6.

Title: Vehicle communication system and method
Inventor: NISHIKAWA KUMIKO
IPC: B60W30/00
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent shortage of communication channels due to traffic snarls, etc., by estimating shortage of channels in a communication zone, where the vehicles pass and performing the control to form a running file of vehicles which are traveling towards the communication zone. SOLUTION: As estimation means 1 monitors the information sent from the roads or vehicles, to estimate the shortage of channels due to traffic snarls, etc., based on the monitored information and notifies a control means 2 of the estimated shortage of channels. Thus, the means 2 gives instructions to plural vehicles traveling towards a relevant communication zone for forming a running file. Therefore, it is regarded that the vehicles temporarily have the same destination, and a running file is formed. In this running file, the road-to-vehicle communication is switched to the vehicle-to-vehicle communication among these vehicles excluding the head vehicle. Then the number of channels are decreased for the control of vehicles. As a result, the shortage of channels can be prevented when the vehicles is caught in a traffic snarl.

Title: Substrate holder and aligner
Inventor: KAWAMURA HIDEJI
IPC: G03F7/22
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To hold a substrate of a large area almost horizontally by making up a correction section installed at a lower position than the horizontal plane where a substrate is held, in such a structure that it may correct the deformation of the substrate caused by the dead weight. SOLUTION: When a mask M is transferred onto a mask table 9, the mask M is chucked and held on the mask table 9 by chucking and holding sections 4, 5, 6 while correction sections 19 support the mask M on both sides of the chucking and holding section 6 to correct the deformation of the mask M caused by the dead weight. The correction sections 19 are disposed nearly opposite to the chucking and holding sections 4, 5 to correct the deformation of the mask M, so that the deformation may be uniform anywhere in the scanning direction to prevent the influence of the deformation caused by the dead weight in the cross-scanning direction on the exposure accuracy.  The upper faces of the correction sections 19 of a deformation correction mechanism 18 are located lower by a distance α than the chucking face of the chucking and holding section 6, and therefore it could influence the exposure accuracy. If such is the case, elevation sections 20, 20 are driven to raise the upper faces of the correction sections 19 a little bit.

Title: Gear finishing machine
Inventor: OURA MASAYUKI
IPC: B23F19/00
Filed: 1985-10-28
Abstract: PURPOSE:To reduce a time for rearrangements and to improve supporting rigidity of a table, by not turning the gear supporting table but changing a relative position for a tool through combination of each independent driving source when the work gear is moved toward the tool. CONSTITUTION:When a table 27 is moved parallelly with the front surface of a bed 21, a motor 25 is driven, and when the table is moved at a right angle with the front surface of the bed, a motor 41 is driven to move a cutter head 38 with a longitudinal feed bed 39, and the table 27 is moved at a right angle with the front surface of the bed 21 relatively to a shaving cutter 36. While when the table 27 is moved in a tilt direction with the front surface of the bed 21, the motors 25 and 41 are simultaneously driven at a speed corresponding to a tilt angle, and the table 27 is moved relatively in the tilt direction for the cutter 36 by simultaneously moving the table 27 and the head 39. Accordingly, the table 27, when its moving direction is changed, eliminates the necessity for rearrangements, and supporting rigidity of the table 27 is improved because the feed direction is in only one direction.

Title: Signal transmission system
Inventor: OI MASAKAZU
IPC: H04B17/00
Filed: 1990-09-10
Abstract: PURPOSE:To reduce the effect of near-end crosstalk and further to reduce radiation noise from a subscriber line by decreasing a signal transmission level to the subscriber line in a range at which an opposite equipment equalizes a loss in a transmission system in which a loss of a transmission line is subject to equalizing processing and the resulting signal is received. CONSTITUTION:A signal transmission means 11 of a transmitter 10 being a sender side at first sends a signal to a transmitter 20 at a prescribed level. An equalizing means 12 of the transmitter 20 being a receiver side compares a received signal level with a prescribed level to discriminate a loss of a transmission line and to equalize the reception signal to a prescribed level. A signal transmission means 13 of the transmitter 20 sends a signal at a level in matching with a maximum equalizing capability of the transmitter 10 based on the loss of the transmission line from the equalizing means 12. An information processing means 14 of the transmitter 20 uses the loss of the transmission line recognized by the equalizing means 12 as loss information and an extraction means 15 of the transmitter 10 extracts loss information of the transmission line from the signal received from the transmitter 20. Thus, the transmitter 10 sends a signal at a level in matching with the maximum equalizing capability of the opposite transmitter 20.

Title: Laminated type flyback transformer
Inventor: NOMURA TAKESHI
IPC: H01F19/04
Filed: 1985-10-25
Abstract: PURPOSE:To reduce the unnecessary radiation of a flyback transformer by induction by setting only the position of winding-start of a coil for a minimum potential layer in a secondary-side winding near the central sections of coils for other layers. CONSTITUTION:Only the position of winding-start of a coil for a minimum potential layer 1a in a secondary winding 1 is set at the central sections of windings for other layers while a winding for the minimum potential layer 1a is wound only on one side. That is, two kinds of positive pulse voltage and negative pulse voltage are generated in each layer for the secondary winding 1, and the crest value of positive pulse voltage is represented by 2/3 and the crest value of negative pulse voltage by 1/3 in this example when the crest value of the case only of the positive pulse voltage of a conventional flyback transformer is represented by 1 in the crest values of the pulse voltage. Accordingly, pulses generated on the secondary side are minimized, thus reducing the unnecessary radiation of a flyback transformer by induction.

Filed: 1992-09-09
Abstract: PURPOSE:To prevent a register output signal from being changed even when a signal for register set is changed by composing a feedback part of an AND gate and an OR gate for set and reset. CONSTITUTION:A signal A for register set is ANDed with a signal, which is logically inverted to an output signal D, by an AND gate 1 for register set. On the other hand, a signal B for register reset is ANDed with the signal D by an AND gate 2 for register reset. The output of the gate 1 is ORed with the output of the gate 2 by an OR gate 3 and inputted to a register 4. Thus, even when the signal A is changed, the output signal of the register 4 is prevented by the operation of the gate 2 from being changed.
