Title: Electrophotographic printer
Inventor: OTOME YUKIO
IPC: G03G15/01
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To change a recording material conveying path for double-side printing or single-side multicolor printing according to a printing purpose by using rollers for reversing a paper sheet moving direction and a paper sheet face between two image forming devices. SOLUTION: In the case of applying bicolor printing to one face of paper, the number and layout of rollers arranged between image forming devices 20, 21 are changed to change a paper moving direction by 180 deg. and to reverse the paper face. At this time, the rollers are always in contact with the opposite face to the toner image transferred face. The rollers 30, 31 used for double-side printing are changed in layout and used for single-side printing to reduce device cost. For instance, black toner is used for the image forming device 20, and red toner is used for the image forming device 21, so that black printing can be applied to one face, and red printing can be applied to the opposite face at the time of double-side printing, while bicolor printing of black and red can be applied to one face at the time of single-side printing.  In order to change printing color, a developer and toner in a developing apparatus have only to be changed to a desired color.

Title: Electric field distribution measuring instrument utilizing electro-optic effect
Inventor: HASHIGUCHI SHOHEI
IPC: G01R19/00
Filed: 1992-06-23
Abstract: PURPOSE:To reduce the size of an electric field distribution measuring instrument utilizing an electro-optic effect. CONSTITUTION:Linearly polarized light emitted form a semiconductor laser light source 1 is led to an electro-optic probe 6 through a half mirror 3, 1/8 wave plate 4, and objective lens 5 after the light is transformed to parallel rays through a collimator lens 2. Reflected light from the probe 6 is led to a double-refraction diffraction grating 8 through the lens 5, plate 4, and mirror 3. The reflected light is separated into orthogonal polarized light components through the grating 8 and the light components are made to incident to prescribed light receiving surfaces 9a, 9b, and 99c of a photoreceptor element 9. Since the grating 8 is used for separating the polarized components from each other, the separating angle of the polarized light components can be increased even when the thickness of the element 9 is not increased. In addition, since the plate 4 is arranged on the forward and backward paths of the light, the inside space of this electric field distribution measuring instrument can be effectively utilized.

Title: Communication device and storage medium
Inventor: KATO ATSUNORI
IPC: H04N1/21
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction that is caused by the infiltration of disturbing external light by inhibiting a control operation by a 1st record controlling means when the disturbing external light is detected and making a recording means execute a series of records. SOLUTION: When disturbing external light is detected during recording receiving data, substitute receiving is switched at the next page, recording by a recording part 12 is not performed and the receiving data is stored as backup data in RAM 3. After receiving is over, the backup data is automatically recorded together with an ink empty mark in the RAM 3 by the part 12. In such cases, if ink empty marks of all of pages are normally detected, the backup data which is automatically recorded is erased from the RAM 3. If the disturbing external light infiltrates a mark sensor 15 at the time of an incoming call, receiving data is recorded together with the ink empty mark over all of the pages by the part 12 and stored as backup data in the RAM 3 at the same time.

Title: Thread fastening control method by self-diagnosis
Inventor: TANIGUCHI SATOSHI
IPC: B23P19/06
Filed: 1990-07-16
Abstract: PURPOSE:To perform reliable detection of seating of a screw by detecting an inflection point by means of a rise signal from a current detecting pat due to seating of a screw and utilizing the number of revolutions of a motor. CONSTITUTION:The number of revolutions of a motor during a time between application of a motor voltage V3 and seating of a screw is decided by a screw. Thus, when a screw is obliquely inserted in a screw hole or is screwed in not in a regular state, even when the infleciton point of the rise of a current I4 is detected by a current detecting pat 9 until the screw is seated, seating of the screw is detected through comparison of the number of revolutions of the motor until the screw is seated with that preset at each screw. When a time i which the scew is seated exceeds a preset given time, processing for defective thread fastening is effected to ouut an abnormal signal to an external device.

Filed: 1988-07-28
Abstract: PURPOSE:To increase the throughput by selectively exposing the periphery of a wafer to rays with an exposure part having two or more tangents to a circle of a radius equal to the length obtained by subtracting the depth of the part to be selectively exposed from the radius of the wafer. CONSTITUTION:For example, an exposure part is shaped into the form of a square of 5mm sides a side on the side of the center of a wafer is shaped into the form of the combined two tangents to a circle of 47mm radius by selectively exposing the wafer to rays to 3mm depth from the peripheral surface. Exposing the wafer to with the exposure part of the abovementioned shape remarkably reduces the difference between the quantity of effective UV rays applied to the center of the exposure part and that applied to the periphery on the side of the center of the wafer of the exposure part, which is unavoidable when a circular exposure part of the prior art is used, and makes the inclination of the cross section of the photoresist steep to shorten the inclined part.
