Patent JP-H01212879-A (JP)
Title: Ice machine
Inventor: TAKEDA YOSHIAKI
IPC: F25C1/04
Filed: 1988-02-22
Abstract: PURPOSE:To reduce an ice making cost and to improve the quality of ice cube, by a method wherein a rotary type injection nozzle is positioned in a manner that a water injection position is asymmetrical and is diffused in a fan-shape, and that a part of a water flow is caused to cross an ice making surface. CONSTITUTION:A hollow arm is supported on a longitudinal shaft 15 rotatably in a horizontal plane and is connected to an ice-making water feed line to form a rotary type injection nozzle 1, which is disposed below an ice maker 13. Nozzles 14 are formed in a slitform manner such that water is diffused in a fan-shape in the longitudinal direction of the arm in positions on both sides situated asymmetrically about the rotary center of the hollow arm and a part of diffused water can cross an ice-making surface. The injection nozzle 1 is rotated at the given number of revolutions, preferably in a range of 20-120 per min. Ice-making water is uniformly injected against all cubic lattices. Since the two nozzles 14 and 14 are different in a position to each ice-making cubic lattice and difference in an injection angle of water, a dead angle region where no water is collided is completely absent, and as a result, ice having the same thickness is formed in each cubic lattice.

Title: Supervising circuit of button telephone set
Inventor: TAKANO JIYUICHI
IPC: H04Q3/58
Filed: 1979-04-02
Abstract: PURPOSE:To secure supervisory effect by connecting a sound collector and loudspeaker to the extension of a button telephone set and by collecting ambient sound from the sound collector and then transferring it to the remote loudspeaker when the extension is free. CONSTITUTION:While button telephone sets 2 and 3 are busy via extension speech lines 5 and 6, information of busy discriminating circuit 19 of sound collector 17 turns OFF microphone amplifier 20 due to voltage drops across resistances 9 and 10 of main unit 1 by a calling current, so that a sound current from microphone 21 will never flow. Since a potential difference between speech lines 5 and 6 is great with extensions free, the information of circuit 19 puts amplifier 20 into operation to send the sound current from microphone 21 to speech lines 5 and 6, so that txtension calling circuit 22 will be in a standby state. Closing switch 23 of loudspeaker 18 puts speaker amplifier 25 into operation by the information of busy discriminating circuit 24, and the sound from the sound collector is emitted from loudspeaker 26. Consequently, a remote supervision can be secured with a relatively- light load.

IPC: G03B27/16
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent an accident associated with the break of a glass or the production of gas being apt to be caused when a flash lamp fires by surrounding airtightly the glass part of the flash lamp with a flexible transparent material and by forming a space at least between them. SOLUTION: This irradiation unit 1 is constituted of the flash lamp 35, a flexible reflection mirror 2 arranged with the lamp 35 as a reflection center, an irradiation window 3 obtained by hermetically sealing the aperture end of the mirror 2 by using a transparent resin film and an insulating material 4 perfectly covering base electrodes 38 and 39. In this case, even when the gas in the lamp 35 flows out because the temperature of the lamp 35 becomes high and the plastic coat thereof is broken, the gas is not diffused on the inside of a thermosensitive plate making unit and the inside is not polluted by the gas because an aperture part is hermetically sealed by the window of the mirror 2. Besides, the broken pieces of the glass of the damaged lamp 35 also remain in the unit 1.  Since the unit 1 is constituted so that the electrodes 38 and 39 of the lamp 35 are perfectly covered with the insulating material 4 and the lamp 35 is prevented form being directly touched by a hand, the possibility of an accidental discharge by static electricity is eliminated.

Abstract: PURPOSE:To execute blast furnace operation under stable furnace condition even in case of increasing using quantity of raw material containing iron and having small grain size without necessary of briquetting treatment, by operating under alternately forming coke layer composing of only coke and ore layer composing ferro coke having low strength and ore. CONSTITUTION:Raw material and fuel charged from upper part of the blast furnace 14 are classified into the ore layer 16, in which the coke 2 and the ferro coke 12 are mixed, and the coke layer 18, in which the ferro coke 12 is not mixed, and charged so as to alternately form them. And, by combustion gas 22 blown from a tuyere 20 and by gravity of the raw material and fuel, in fusing zone 24 in the blast furnace 14, the ore 2 is made to semi-melting state and the ferro coke 12 is made to fine grain.
