Title: Structure of door for high-frequency heating apparatus
Inventor: SATOU TOSHIO
IPC: H05B6/76
Filed: 1984-05-23
Abstract: PURPOSE:To prevent an inner barrier from fogging, by preventing residual content of sealing component from evaporating, by using a sealing compound whose decreasing rate by heating is small. CONSTITUTION:A screen and a contacting piece are monolithically molded on the backside of a door board 2. A screen contacting piece 9 on which a number of holes 8 are punched so as to observe the inside of a cooking chamber, is tightly fixed to the door board 2 by welding, so as to cover the opening 1 of a door board 2. An inner barrier 11 is disposed in a channel 10 provided on the back side of a screen contacting piece 9, and the inner barrier 11 is closely fixed to the piece 9 by filling an adhesive sealing compound 12 between the inside of a recession 10 and the outer periphery of an inner barrier 11. An adhesive sealing compound 12 of which decreasing rate by heating is nearly below 4% is to be used when the parts are jointed. When this arrangement, the residual content in silicon is scarecely recognized to scatter around, and fogging will not occur on the inner barrier.

Abstract: PURPOSE:To attain the continuous call of a question and an answer without effecting a transportation means for the receiving of an answer signal by making a power transportation signal and the answer signal from a responder into a transmission means by a different physical event. CONSTITUTION:A question signal by a high frequency power signal to occur by a signal generator 1 is radiated in the air as an electromagnetic wave from an antenna 2 for transmission. A receiving antenna 2 to constitute a responder receives the supply of a high frequency power from the radiated electromagnetic wave as the question signal and a direct current output signal is generated as the output signal of a rectifying smoothing circuit 41. A question responding signal generator 42 generates the answer signal to the question as the signal on an amplitude axis or an signal on a time base with the output signal of the rectifying smoothing circuit 41 as a power source. The output signal of the sound wave signal generator generated electrically by the responder is converted to a sound and radiated in the air by an electric sound converter 5. Thus, with the signal generation of a frequency to meet the characteristic of the electric sound converter 5 as a purpose, for a sound wave generator 43, the sound radiated in the air is received by a sound electric converter 6 at the question side, converted to an electric answer signal and amplified with an amplifier 7. When the frequency generated by the sound wave generator 43 is a voice frequency, the output signal of the electric sound converter 5 can be heard with a voice.

Abstract: PURPOSE:To make it unnecessary to trouble a service man and a user at the time of starting the titled device as in the past, by providing lubricating action in its initial state, and scraping a residual developer by only the contact accuracy between the tip edge line part of a blade and a photosensitive drum, successively and automatically, whenever the device is used. CONSTITUTION:When the device is operated for the first time, and a photosensitive drum 20 executes rotation, a lubricant 66a slides and contacts the surface of the photosensitive drum 20, therefore, a frictional force against a blade is reduced, such a failure as turning-up, etc. does not occur. Also, since a sticking force between the lubricant 66a and the blade 66 is small, particles of the lubricant 66a are peeled off gradually at every one sliding contact, and when the photosensitive drum 20 executes a rotational operation several times, all the particles are eliminated from the blade 66. However, before this state, the blade 66 and the photosensitive drum 20 are conformed with each other, therefore, the photosensitive drum 20 contacts the edge line of the blade 66 with high accuracy in accordance with the initial fitting accuracy, and a copy image of good quality is obtained without causing rolling-up, filming, etc.

CONSTITUTION:A sphere 28 of which a surface is polished smoothly comes in contact with recording paper 25, and one end of a compression coil spring 29, i.e., one kind of an elastic component is engaged with the sphere 28. The other end of the compression coil spring 29 is engaged with a pressure sensor 27, and surface smoothness of the recording paper 25 to be detected with the sphere 28 is transmitted to the pressure sensor 27 via the spring 29. The recording medium 25 is carried by being pressed between a paper pressing roller 17 and a platen roller 1 and besides, quality of paper is detected by coming in contact with the paper sensor 27. When the recording paper is heat sensitive paper or transfer paper, since paper quality is thin and the surface of paper is smooth, pressure is detected to be low with a paper sensor 27, and when rough paper, the paper quality is thick and the surface is rough, the pressure is detected to be strong. Then, quality of rotation to be given a motor is determined from detected results of the paper sensor 27 and a ribbon sensor 22 to control pressing force of the head 1. Printing quality can be achieved to be improved thereby.
