Title: Document processor
Inventor: JIYOUDAI AKIYOSHI
IPC: B65H83/02
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To make a document on a document tray so as not to travel even in the case where a document conveyor system comes to a state of being tilted to process a paper jam or the like by preventing such a document as turning to the high position side of the document tray when an upper body is opened, from being shifted to the low position side. SOLUTION: When a sensor installed in a lower body detects such an abnormal status that a device body has to open an upper body due to a paper jam and suchlike, slightly opened or the like, a discharge motor of a discharge roller is rotated in reverse. Then, a slider 245 rotates, and thereby a torsion spring is distoted as far as a rotational difference lying between this slider 245 and a document pressing laver 246, and a pressing force is given to this document pressing lever 246, therefore the sensor detects an off edge of a detecting plate 255, stopping a reverse rotation of the discharge roller.  Thus, since the discharge document on a document tray 60 is forcibly pressed by the document pressing lever 246, this discharge document at the high position side is prevented from being shifted to the lower position side even if the upper body of a copying machine body is opened and the document tray 60 comes to a state of being tilted.

Title: Heat treatment process of high molecular material
Inventor: ISHIHARA HIDEAKI
IPC: B29B13/02
Filed: 1984-02-27
Abstract: PURPOSE:To contrive to improve heating speed by providing the preheating process where gasified and specified heating medium is caused to be in contact with high molecular material and is condensed thereon, and the heating process where high molecular material having the (epsilonrtandelta) value raised by preheating is directly heated by microwave irradiation. CONSTITUTION:The gaseous heating medium 9 which is pressure transferred from a pressure transferring device 11 is brown in the same direction as the running direction of high molecular material 2 through a blowing nozzle 10. When the gaseous heating medium 9a is caused to be in contact with the high molecular material 2, it is condensed and becomes heating medium 9b. Said heating medium adhers to the high molecular material 2 and raises its temperature, giving its condensation heat to said high molecular material. Though the heating medium is heated by absorbing microwave, the value (epsilonrtandelta) of said medium 9 is selected more large than that of high molecular material at low temperature, whereby said medium absorbs the microwave effectively therein and is heated quickly. When the high molecular material 2 is preheated and the value (epsilonrtandelta) thereof is fully heightened, it absorbs directly microwave and is heated to the temperature of heat treating operation at high speed, and further simultaneously, the condensed heating medium 9 is removed by evaporation. Thus, the heating process is finished.

Filed: 1994-03-07
Abstract: PURPOSE:To reduce the reception error by multiplexing a signal transmitted by the SS transmission method and an OFDM digital signal in a broad band including a channel for the transmission of the digital signal. CONSTITUTION:Information with high importance is sent by using the SS(spread spectrum) transmission method and other information is sent by using the OFDM (orthogonal frequency division multiplex) transmission method through a channel of the same frequency band. That is, the transmission information is classified by an information classification circuit 8 depending on the importance of information and the important information is sent by using the SS transmission methods 2, 5 and the other information is sent by using the OFDM transmission methods 3, 7. For example, as to video information coded by the MPEG II, the information classification circuit 8 classifies the information into G.O.P header information with high importance and other information. Then the G.O.P header information with high importance is sent by the SS transmission methods 2, 5 and the other information is sent by using the OFDM transmission methods 3, 7. An adder 4 multiplexes signals modulated by modulators 2, 3 on a same channel.

Title: Monochrometer
Inventor: HARADA TATSUO
IPC: G02B5/18
Filed: 1989-02-17
Abstract: PURPOSE:To enable removal and lowering of coma abberation, spherical abberation and the like of a spectral image by making a lattice groove array of a diffraction grating unequal in interval. CONSTITUTION:An angle of incidence of a light beam 21 which is emitted at the center of an incident slit 1 and reflected on a spherical surface 2 to be incident at a point P at a distance W from the center on a lattice surface of a diffraction grating 3 gives an angle deltaw different from an incident angle delta0 at a diffraction grating 0 for an abberation of spherical mirror 2. It is also necessary to make an angle of diffraction betaw different from an angle beta0 at the center because of an abberation of a spherical surface 4 in order that light diffracted at the point P should be reflected on the spherical mirror 4 to pass the center of an outgoing slit 5. In this manner, the diffraction grating 3 herein used has different grating groove intervals corresponding to positions on the surface of the diffraction grating. This allows the converging of a n-order diffraction light with a wavelength emitted at the center of the slit 1on the center of the slit 5 within a plane containing centers of the spherical mirrors 2 and 4 and the diffraction grating 3.

Abstract: PURPOSE:To effect an advance of long distance by a single process by forcing a propulsion body provided in an underground pipe and an expanded head for housing a forward end of the underground pipe provided in a leading body of said propulsion body into earth and detaching the underground pipe from said propulsion body to push said pipe. CONSTITUTION:A propulsion body 7 and an underground pipe 8 are forced into earth by means of a propulsion machine 4, while sliding agent is fed into a storage chamber 16 through a feed pipe 20. A leading body 12 and an expanded head 15 are forced into the ground by compaction method and an inner cylinder 5 is rotated, when required, to adjust the direction of a direction correcting head 10, whereby they are pushed while their directions are being corrected. The sliding agent having overflowed from the chamber 16 is passed through the gap between the pipe 8 and a protection cylinder 14, so that the agent is supplied to the entire outer surface of the pipe 8, reducing thereby the circumferential resistance of the pipe 8 and hence damage of underground pipe 5 is avoided. As a result, an advance of long distance is achieved precisely and construction efficiency can be greatly improved.
