Title: Incinerating method and incinerating furnace
Inventor: MATSUMIYA KATSUTO
IPC: F23G5/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To positively burn material to be incinerated. SOLUTION: A hearth 120 having water permeability is formed of heat resistant member obtained by mixing gravel with sand in a combustion chamber 2 formed in a furnace body 100. An air supply tube 130 having a plurality of discharge ports 130a is embedded in the hearth 120. A water supply system is connected, in addition to an air supply system, to the tube 130. In the case of burning material to be incinerated of the chamber 2, water is previously supplied to the tube 130 via the water supply system, stored in the tube 130 and the hearth 120 is wetted therein. Thus, even when melted plastic is stored in the hearth 1 while the material is burned to the degree of about 1/4, it is cooled with the water of the hearth 120, and solidified so as not to be introduced into the tube 130.  When the material is burned to the degree of about 1/4, the air is supplied from the air supply system to the tube 130 to give the air to the material directly on the hearth 120 via the ports 130a and the heath 120 to completely burn the material.

Title: Image pickup device
Inventor: IIDA KIYOSHI
IPC: G02B26/12
Filed: 1988-08-29
Abstract: PURPOSE:To increase scanner efficiency and to pick up images of scenes in two different directions by one detector at the same time by picking up images in >=2 directions or different visual fields by using different surfaces of a rotary polygon mirror for the scanning of different pieces of luminous flux. CONSTITUTION:Plural, for example, two afocal lens systems 6 and 6' are combined with the six-surface polygon mirror 1 and arranged so as to use different polygon mirrors, e.g. 1st and 2nd surfaces. Light passed through the afocal lens 6 is reflected by the 1st surface to pass through an optical path 1 and enters the detector 3 through a relay lens 4 and a vibration mirror 2. The time when the signal is made incident on the detector 3 is outputted at the timing of the signal of the incident light passed through the optical path 1. Light passed through the afocal lens 6', on the other hand, enters the detector 3 through an optical path 2 and is outputted at timing different from the signal of the optical path 1. Thus, the scenes in two different directions are picked up by one detector 3 at the same time.

Title: Data communication system
Inventor: YONEZAWA MASAAKI
IPC: H04L12/28
Filed: 1988-08-29
Abstract: PURPOSE:To decrease the effect of an obstacle standing on the way of a communication path and to ensure data communication even with a low transmission output by sending a data signal of the 1st frequency signal toward an auxiliary station from plural communication stations when the 2nd frequency signal is not outputted from the auxiliary station. CONSTITUTION:When a transmission request takes place in a communication station N1 at a time T1 and other communication stations do not make communication in this state and a communication request is generated from a transmission request means 3 in a transmission request means 3 at the time T1 in the communication station N1, an f2 signal detection means 4 receives the request to detect whether or not the 2nd frequency f2 signal is detected from an auxiliary station NO at a time T2. When the 2nd frequency signal is not detected, it is discriminated that other communication station is not communicated, an f1 signal transmission means 5 sends a data toward the auxiliary station NO by the 1st frequency signal f1 at a timer T3 or thereafter. Thus, each communication concentrates the transmission energy toward the auxiliary station to attain accurate data communication without using a large transmission power.

Filed: 1993-08-30
Abstract: PURPOSE:To attain sure communication by automatically selecting a previously written frequency information by switching at the time of selecting a dead channel. CONSTITUTION:A selected channel is read out from plural channels CH1 to CH6 of a keyboard 40. Frequency information corresponding to the read channel is read out from a memory 30. In this state, a judging means judges whether the read frequency information indicates a dead channel or not. When the existence of a dead channel is judged, a switching means switches the channel to a channel whose channel number is smaller than the current channel only one and frequency information corresponding to the switched channel is read out. Namely channel numbers are successively descended until frequency information is detected. When a dead channel is selected, its frequency information is automatically switched to previously written frequency information.

Besides, the frequency characteristic of a high frequency band is determined by R2 to R4 and C2, but by selecting R2 to R4 properly, cut-off frequency FH can be shifted to lower frequency. Thus, the reduction of the parts and the simplification of control can be attained.

Abstract: PROBLEM TO BE SOLVED: To shorten throughput time and to improve the cleaning performance by cleaning away residual toner by means of an intermediate transfer roller which is positioned at downstream side from a transfer nip part where toner image is transferred. SOLUTION: A transfer bias is applied to the intermediate transfer roller 6 provided with a cleaning roller 21 so as to be freely away from and nearer to the roller 6.

Thus, the transfer and cleaning are carried out almost in parallel with each other. Also, by generating a potential difference between the intermediate transfer roller 6 and cleaning roller 21, the toner is removed from the transfer roller 6 to the cleaning roller 21 by the potential difference.
