Title: Squeegee rubber for screen printing
Inventor: ITO YOSHIO
IPC: B41F15/44
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To accomplish reinforcement and to perform stably good printing by laminating integrally the first and second equeegee rubber sheets respectively with a specified hardness with an adhesive with excellent solvent resistance. SOLUTION: A rigid squeegee rubber sheet 2 is inserted into the central part of a squeegee rubber so as to make the first flexible squeegee rubber sheets 1 with good followability to screen printing and a rubber hardness of 50-75 degrees on both faces of the second rigid squeegee rubber sheet 2 with a rubber hardness of 76-90 degrees to reinforce it to deformation and to make a sandwich structure wherein the both faces of a squeegee rubber sheet 5B are symmetrical. As it is the sandwich structure wherein both faces are symmetrical, warpage and twisting are less as the equeegee rubber 5B and the both faces can be effectively used. By using the squeegee rubber like this, precise pattern printing for width of a conductive body of less than 0.2mm and screen printing for fine letters of less than 1.0mm can be clearly and stably performed.

Inventor: IRIE YOUICHIROU
IPC: G03B27/34
Filed: 1982-07-23
Abstract: PURPOSE:To project accurately light on a photoreceptor, by operating an angle setting means which slants a final reflecting mirror to an optical axis in relation to the operation of a position setting means which moves the final reflecting mirror along the optical axis. CONSTITUTION:There is no problem in unmagnification copying. In variable power copying, however, a lens 14 and the 2nd reflecting mirror 16 are placed as shown by two-dot chain lines 14A and 16A and the lens 14 is slanted clockwise by an angle theta to the optical axis 20. In this state, when a transparent plate 2 is moved as shown by an arrow 18 at a speed 1/M (M; copying magnification) as fast as the moving speed of a photoreceptor 4, an image of an original O is projected on the photoreceptor 4 in the normal direction of a rotating drum 6 at an intersection P2 to the surface of the photoreceptor 4 to form an M-fold electrostatic lantent image corresponding to the image of the original O on photoreceptor 4.

Title: Method for recovering terephthalic acid and ethylene glycol from polyethylene terephthalate
Inventor: OKU AKIRA
IPC: C07C63/26
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To effectively use resources and reduce environmental pollution caused by waste by recovering raw materials, terephthalic acid and ethylene glycol, from a polyethylene terephthalate(PET) under a relatively mild condition and in a short time. SOLUTION: This method for recovering terephthalic acid and ethylene glycol from a polyethylene terephthalate is to contact granules, powder, small pieces, a mass of them or a mixture of two or more of them of the polyethylene terephthalate with sodium hydroxide in ethylene glycol and separate the produced sodium terephthalate as a solid. The reaction is carried out, when treating a material having a shape with a small surface area, at a high temperature or without raising the temperature by adding a promotor (e.g. THF) at a room temperature-195 deg.C. Sodium hydroxide is preferably used in 1-3.5 for carboxylic groups in the PET. In case of a plastic waste containing >=50% of the PET, a volume ratio of the PET for ethylene glycol is brought to be <=35%.

Title: Crystal oscillation circuit
Inventor: OIKAWA KOJI
IPC: H03B5/36
Filed: 1985-06-14
Abstract: PURPOSE:To improve improper start due to characteristic variation of a crystal oscillator and variation in circuits and also to eliminate the effect of a power voltage rising time by providing a circuit where a base bias voltage of a transistor (TR) rises rapidly slower than a collector voltage. CONSTITUTION:The phase of a signal outputted from a collector of a TRQ1 is changed by 180 deg. by a pi circuit comprising the crystal oscillator 1 and capacitors C1, C2, and only the same frequency component as a resonance frequency of the crystal is fed back to a base of the TRQ1, then the oscillator is oscillated at the resonance frequency of the oscillator 1. Even when the leading of a power voltage is slow, if the voltage does not rise over the Zener voltage of a Zener diode D1, a TRQ2 is not turned on and no base bias voltage is fed to the TRQ1, then the circuit is operated without being affected by the leading time of the power voltage. Since the base bias voltage of the TRQ1 is applied rapidly as soon as a current flows to the Zener diode D1, a large exciting energy is given to the crystal oscillator to improve the start performance of the oscillation circuit.

Title: Magnetic recording method and device for photographic film
Inventor: SASAKI WATARU
IPC: G03B17/24
Filed: 1995-05-26
Abstract: PURPOSE: To make it possible to exactly reproduce magnetically recorded first binary data or last binary data. CONSTITUTION: Recording current IH flows in a solid line arrow direction to a coil 12a when first, fourth ports P1, P4 are an L level and second, third ports P2, P3 are an H level. The recording current IH flows in a direction reverse from the solid line arrow to the coil 12a when the first, fourth ports P1, P4 are the H level and the second, third ports P2, P3 are the L level. An 'S magnetized region' is recorded when the port P1 is the H level and a port P2 is the L level. The binary data is a '1' when the phase at which the 'N magnetized region' inverts to the 'S magnetized region' is a first half of the one recording period TT. The binary data is a '0' when this phase in the second half.  The 'S magnetized region' is prerecorded just before recording of the 'N magnetized region' of the first binary data and the 'N magnetized region' is end recorded right after the 'S magnetized region' of the last binary data. A current control section 10b controls the recording current so as to gradually increase the recording current IH at the time of the prerecording and to gradually decrease the recording current IH at the time of the end recording.

Abstract: PROBLEM TO BE SOLVED: To improve the original read efficiency by detecting a movement quantity of an image read means in the horizontal and vertical directions on an image of an original thereby suppressing production of a triangular overlapped scanning area due to duplicate scanning of an image sensor. SOLUTION: This reader is provided with encoders 3a, 3b to detect a moving quantity in the horizontal (X axis) direction and an encoder 6 to detect a moving quantity in the vertical (Y axis) direction, and a Y axis direction moving wheel 5 is placed at a position no in contact with an original simultaneously with other wheels when X axis moving wheels 3a, 3b are both in contact with the original 1000.
