Title: Radio transmission and reception system
Inventor: YOKOTA TAKAHIRO
IPC: H04B7/00
Filed: 1988-08-25
Abstract: PURPOSE:To improve efficiency, to intermittently operate a transmitter-receiver so as to reduce consumption power and to wholly reduce the consumption power, to miniaturize and lighten a portable radio equipment by time-compressing a transmission signal, widening a band width, and increasing an output. CONSTITUTION:The signal from a transmitter 1 comes to a time-compressed intermittent signal as a result that a speed converter 2 operates in synchronizing with a high speed clock from a synchronous control part 5. It is time-compressed to one tenth of the original signal, for example. The time-compressed signal is transmitted to a transmitter 3, modulated and intermittently transmitted from a transmission antenna 4. The time-compressed signal is intermittently inputted to a reception antenna 6, and the reception signal is received in a receiver 7 and demodulated and then transmitted to the speed converter 8. Since the speed converter 8 operates in synchronizing with a low speed clock from the synchronous control part 5, the time of the signal is expanded. The time expansion is a ten fold original demodulation signal, and accordingly the signal changes into a continuous sound signal and is transmitted to a receiver 9. The transmitter 3 and the receiver 7 are applied with power synchronized with transmission and reception signals from the synchronous control part 5.

Filed: 1985-09-26
Abstract: PURPOSE:To prevent a sample dissolving part and its peripheral part from being oxidized by atmospheric air which flows in by flowing carrier gas backward, passing it from a sample dissolving furnace side to a sample introducing means side, and discharging the gas from a flow passage when the sample is changed. CONSTITUTION:A sample 6 on a receiver 17 is fallen down and dissolved at the sample dissolving part 20 and its produced gas is flowed through a carrier gas circulation flow passage, so that the amount of oxygen in the sample is measured by an oxygen sample 9. When the sample is changed, changeover valves are operated to discharge the carrier gas from an intake 11 to the outside by the pump 15 through the changeover valves 2, 4, and 3, a sample introducing means 7, and the changeover valve 4. Atmospheric air flowing in when a lid 16 is opened is discharged together with the carrier gas. The gas is flowed backward a while even after the lid 16 is closed to discharge the atmospheric air completely. Thus, the sample dissolving part 20 and its periphery are prevented from being oxidized by the atmospheric air which flows in when the sample is changed.

Title: Structure member
Inventor: SATO TATSUSHI
IPC: E04C3/292
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a structural member which is made lighter as the prevention of wrinkle and rigidity are maintained. SOLUTION: A structural member 10 is continuously seam-welded between a pipe 18 and a joint 14 severally arranged at both the ends of the pipe 18 and sealed up. The pipe 18 is a nonwater-permeable and nongas-permeable pipe, and wood is inserted into its inside, and the joint 14 is stuck to the end face of the wood with an adhesive agent. Since the wood in the pipe 18 is shut off from the outside world and not supplied with water and oxygen, its rot due to wood rotting germ or a termite can be prevented. Thus the structural member 10 can be made lighter as the prevention of wrinkle and rigidity are maintained. Therefore the structural member 10 is improved in durability and can be used for a long period.

Title: Combustion device for coal-water slurry
Inventor: KOBAYASHI AKINOBU
IPC: F23K1/02
Filed: 1986-09-10
Abstract: PURPOSE:To obtain a spray droplet of a desired particle size, by controlling the feeding rate of fluidity modifier so that a slurry fuel may show a fluidity except dilatant fluidity, at least, or it may show the fluidity which decreases the dilatant fluidity. CONSTITUTION:A coal-water slurry (CWS) is stored in a CWS tank 1. It is fed out of the CWS tank and is fed into a mixer 9 by a pump 5 after the flow rate of CWS is measured by a flow meter 7. When the CWS stored in the CWS tank 1 has a dilatant fluidity, the feeding rate of a fluidity modifier is controlled so that a signal from a fluidity detector 10 comes to show non- dilatant fluidity at least, or the fluidity modifier can weaken the dilatant fluidity of CWS stored in the CWS tank 1. The feeding rate of a spray medium is controlled in accordance with the fluidity 4 determined by a signal from the fluidity detector 10. If a signal from the fluidity detector 10 shows a dilatant fluidity, for example, the particle size of spray droplet is prevented from increasing by increasing the flow rate of a spray medium.

Title: Semiconductor light emitting device
Inventor: OSAKA SHIGEO
IPC: H01S5/00
Filed: 1984-10-09
Abstract: PURPOSE:To prevent genereation of noise at the time of modulation by a method wherein an optical absorption layer, which has band-gap not larger than band- gap of light emitting region in the middle of the light emitting region in a semiconductor compound laser device where plural parallel light emitting region are formed. CONSTITUTION:When conductive type is changed under the condition that carri er density of an n type active layer 13 is designated as 3X10<18>cm<-3> and carrier density of a p type diffusion layer 17, 18 is designated as more than the above- stated density, band-gap Eg1 of a light obsorption layer 22 in the diffusion layer 17 is about 70meV smaller than the band-gap Eg0 of light emitting region 19 in a diffusion layer 18. As the result, lateral mode-guided laser oscillation can be performed by reason that the light emitting region 19 generates difference of flection ratio as light emitting stripe. The light absorption layer 22 works only as a light absorber because electric current is not sent, and prevents optical interaction between mutual light emitting region 19 caused by shielding lateral irradiated light (EL). So independent operation can be done even at the state of laser array formed closely.

Title: Distribution board box
Inventor: HIRAI YUJI
IPC: H05K5/00
Filed: 1987-08-26
Abstract: PURPOSE:To improve an external appearance and laying operability and to improve coating quality by bending the end of a peripheral side plate of a drain hole in coincidence with the bending shape of a bent piece. CONSTITUTION:The end 13 of a peripheral side plate 2 is bent in coincidence with the bending shape of a bent piece 2b at both sides of a drain hole 7. Accordingly, the end 13 does not protrude at its edge as a conventional one, but is the same as the bending shape of the piece 2b. The end 13 is bent by first punching it with a die and then bending the end 13 of the plate 2 by pressing. Further, the piece 2b is bent to form the plate 1. Thus, since the end of the plate 12 coincides with the bending shape of the piece 2b, if a direction of an arrow is set to a draining direction, coating drop 14 does not fall toward the hole 7 to eliminate the protrusion of the drop 14 outside the plate 2. Thus, its external appearance is improved, and the coating is scarcely exfoliated in a practical work.
