Title: Feeding method of continuous multifilament yarn
Inventor: ANAHARA AKIJI
IPC: D01H1/00
Filed: 1980-09-01
Abstract: PURPOSE:To separate an opened filament group from a liquid efficiently and wind the filament group around a spindle stably, by means of a fluid-permeable body provided after the spindle. CONSTITUTION:A multifilament yarn 2 having substantially no twist is delivered positively at a higher speed than the surface speed of a spindle 7, jetted with a high-speed fluid 24 from a nozzle 20 and made to collide with a collision plate 27 consisting of a plane, curved surface or a combination thereof before the nozzle 20. The fluid 24 is then made to slide on a guide plate 28 while being diffused, and fed to a fluid-permeable body 29 provided after the spindle 7 to permeate only the fluid 24. The remaining continuous filament yarn 2 is wound around the spindle 7 efficiently and then withdrawn to give a yarn like a spun yarn.

Title: Functional telephone system
Inventor: AMAMIYA HISATOSHI
IPC: H04M1/274
Filed: 1987-05-19
Abstract: PURPOSE:To recover the state into the state just before power failure with very high reliability at the point of time of power failure restoration by storing novel control information in a dial memory of a dial IC subjected to battery backup in the low power consumption mode during power failure. CONSTITUTION:When control information is generated novelly, a control means brings the dial IC into the control mode and stores the control information in the dial memory of the dial IC. The control information stored in the dial memory is read properly based on the control signal from an external device such as s main CPU. A standby circuit 20 detects a voltage of a station power supply or AC 100V commercial source and the dial IC 16 is in the backup state by a battery 19 at a prescribed voltage or lower and brought into the low power consumption mode. Thus, the content of the dial memory is preserved.

Title: Polarization direction switching unit
Inventor: INOUE YASUYUKI
IPC: G02F1/035
Filed: 1992-05-14
Abstract: PURPOSE:To evaluate a polarization characteristic of a waveguide type optical part precisely over a wide range of light wave length by installing one fiber of two polarization maintaining optical fibers on the other fiber in a condition of being twisted by 90 degrees. CONSTITUTION:A polarization direction switching unit is composed of N (optional positive integer) X two optical space switches 3, a 2X2 polarization holding photocoupler 12 and two polarization maintaining optical fibers 1 to connect these to each other. One polarization maintaining optical fiber 1 is installed on the other polarization maintaining optical fiber 1 in a condition of being twisted by 90 degrees. Thereby, the polarization direction of light incident on the photocoupler 12 becomes different on condition that through which the light is propagated among the two polarization maintaining optical fibers 1. Thereby, the polarization direction of an output light of the 2X2 polarization maintaining photocoupler 12 can be rotated by 90 degrees by switching the N - two optical space switches 3 to/from each other. Since a twist of the polarization maintaining optical fibers 1 is used this polarization direction switching unit as a polarization rotating mechanism, the dependency on a wave length is not required.

Title: Production of quartz glass thin film
Inventor: ARAI KAZUO
IPC: C23C16/40
Filed: 1987-05-19
Abstract: PURPOSE:To obtain quartz glass thin film without residual -H and -OH in the film, by feeding a silane based gas and oxygen and further a fluorine-containing silane based gaseous compound and forming the quartz glass thin film on a substrate by photochemical vapor deposition (photoCVD) method. CONSTITUTION:A silane based gas and oxygen and further a fluorine-containing silane based gaseous compound are fed to form a quartz glass thin film on a substrate by a photochemical vapor deposition (photoCVD) method. A raw material, such as Si2H6 used for producing the quartz glass thin film using the photoCVD method can be used as the silane based gas. The quartz glass thin film is grown from a raw material, such as the silane and oxygen, on the substrate by rays irradiated from a light source, such as deuterium lamp by this method for production. The fluorine-containing silane based gaseous compound mixed in the raw material generates fluorine-related radicals by reaction with silane based radicals formed by photolysis and the radicals are capable of removing or substituting -H or -OH on the film surface during growth by etching effects.

Title: Printing mechanism
Inventor: ONISHI KAZUMASA
IPC: B41J2/32
Filed: 1992-05-14
Abstract: PURPOSE:To reduce frictional force between a print head or a platen and a printing paper so as to prolong the lifetime of the head and save labor by fixing to the print head a piezoelectric device for vibrating the head in a direction rectangular with respect to the face of the printing paper. CONSTITUTION:In operation of a printing mechanism, a piezoelectric device 24 is vibrated by alternating voltage applied by a power source device 30. The vibration is transmitted to a print head 12 to which the device 24 is fixed, so as to generate vibration at the head 12. The device 24 is fixed such that a vibration vertical with respect to its back face 22 to be fixed generates. Accordingly, the head 12 vibrates almost rectangularly with respect to the flat face of a printing paper 16. This vibration is ultrasonic vibration of 20KHz or more and does not become an adverse factor of noise. The amplitude of the ultrasonic vibration of the head 12 is 1mum or less. Therefore, no adverse effect due to lowering of heat conduction from the head 12 will be exerted on printing, so that print quality will not deteriorate. Further, pressing force against the paper 16 is restrained by the vibration of the head 12, so that frictional force to be generated between the two is reduced and the lifetime of the head 12 will be prolonged.

Abstract: PURPOSE:To confirm the telephone number of a transfer destination visually by generating identification image information including the telephone number of the transfer destination and transmitting the information to the destination when a command revising the transfer destination comes. CONSTITUTION:Suppose that a transfer destination set from a facsimile equipment A to a facsimile equipment B is revised into from the equipment A to the equipment C by the operator of the equipment B among the facsimile equipments A, B, C located at different points. When the operator uses the ten-key of the equipment B to command revision of the transfer destination to the equipment A and to input a telephone number of the transfer destination, a CPU 12 of the equipment A stores the telephone number of the transfer destination to a RAM 16 to revise the telephone number of the transfer destination stored in an EEPROM 18 to that of the equipment C. Then the transfer image information to be stored in the RAM 16 is started. When the operator requests a status list by prescribed key operation, the CPU 12 of the equipment A generates image information of the status list including the telephone number of the transfer destination and sends it to the equipment B. Thus, the telephone number of the transfer destination is confirmed and data are surely transferred.

Title: Carrier recovery circuit
Inventor: YAJIMA YASUO
IPC: H04L27/227
Filed: 1984-06-15
Abstract: PURPOSE:To prevent pseude synchronizing lock by detecting a level of an input carrier, retarding it for a prescribed time and controlling a switch placed in a circuit where are output of an automatic sweep oscillator is inputted to a voltage oscillator. CONSTITUTION:When an input carrier is fed to a level detector 12, this level is detected, the output is brought into 0 level from 1 level, a delay circuit 13 delays the level by a time 10ms sufficient for the synchronizing lock and the result is fed to a switch SW2. Thus, when the input is interrupted, it is applied again, the frequency of the voltage controlled oscillator VCO9 reaches 650MHz, the pseudo synchronizing locking is caused and an output of an NOT circuit 11 goes to 0 level, but since the output of the delay circuit 13 does not go to 0 level, the SW2 remains turned-on and the frequency of the VCO9 is fluctuated around the frequency 700MHz of the input signal by using the automatic sweep oscillator 10. When the output of the delay circuit 13 goes to 0 level after nearly 10ms and the frequency of the VCO9 goes to 700MHz, the SW2 is turned off and the VCO9 outputs a recovered carrier.
