Title: Method for ensuring emergency call communication for personal handy phone system
Inventor: FUJII MORIHIRO
IPC: H04W4/90
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain a method for ensuring PHS emergency call communication capable of making an emergency call speech by means of a CS even is there is no idle channel among general speech channels when a PHS terminal makes an emergency call to a police station or a fire station. SOLUTION: Upon the receipt of a call from a PHS terminal 10, a CS 20 detects whether or not there is an idle channel in general speech channels 31, and when there is any idle channel, the CS 20 makes call connection processing to the idle channel, and when no idle channel is available, the CS 20 detects whether or not a call destination number is a preset emergency number. The CS 20 rejects the call when the call destination is other than emergency numbers on the basis of the result of detection of the call destination number, and when the call destination number is an emergency number, the CS 20 detects whether or not there is an idle channel in maintenance channels 32. The CS 20 rejects the call when there is no idle channel in the maintenance channels 32 and makes call connection between the PHS terminal 10 and the caller through the maintenance channel 32 when there is any idle channel in the maintenance channels 32.

Abstract: PURPOSE:To enhance the deposition yield on a target by atomizing liq. starting materials by ultrasonic vibration after which the atomized particles are mixed with gas contg. oxygen and hydrogen, burned, and hit on the target. CONSTITUTION:The atomization of liq. starting materials for a glass composition is controlled by changing the quantity of electric energy to increase the amount of the materials atomized without raising gas pressure. For example, liq. starting materials fed to front edge 13 of vibration magnifying horn 2 from feeder 5 through feed pipe 6 are converted into fine particles by vibration with ultrasonic vibrator 1, and the particles are spouted from nozzle 7' with H2 gas of arrow 10. The H2 gas is ignited in nozzle 7' and burned to generate flame 16 contg. glass soot forward together with inert gas and oxidizing gas from triple-tubed nozzles 8', 9'. By spraying flame 16 upon target 18 rotating in the arrow 20 direction and moving in the arrow 19 direction, glass soot 17 is deposited on target 18.

In the layered steel plate 4b, an inner and outer periphery jointing part 17 is formed as a reinforcing means which joints a magnetic pole part 6 and a yoke part 8 with each other in the magnet inserting hole. In the number of the overall layers consisting of the layered steel plates 4a, 4b, at least two of them are the layered steel plates 4b, and the optimum number of the layered steel plates 4b is selected by considering motor efficiency degradation due to leakage flux from the inner and outer periphery jointing part 17.

Title: Burning apparatus
Inventor: IMAJIMA MITSUHIRO
IPC: F23D11/10
Filed: 1989-04-11
Abstract: PURPOSE:To reduce the cost and noise without causing yellow flame to be generated by disposing an air supply tube and a nozzle to penetrate the mixing tube tangentially, and disposing a barrier in the mixing tube in the upstream side of the mixture flow relative to the location where the air supply pipe and the nozzle are opened. CONSTITUTION:The fuel supplied from the nozzle 17 is evaporated in the mixing tube 11 which is heated hot by a heater 12 and is mixed with the air from the air supply pipe 15 to become a mixed gas. As the air supply pipe 15 and the nozzle 17 penetrate the mixing tube 11 tangentially, the mixed gas is made a spiral flow to enhance the mixing of air and evaporated fuel, and collides a barrier 20 disposed in the mixing tube 11 to be deflected to the center of the mixing tube 11, facilitating its smooth flow to the throttled opening 14 in the burner head 13. The mixed gas ejected into the burner head 13 is ejected from the flame holes in its circumferential ball. Because the air and fuel is well mixed in this manner, yellow flame is seldom generated, and the capacity requirement for the blower fan becomes small, allowing a reduction in noise and cost down.
