Title: Semiconductor image-position detecting element
Inventor: IDESAWA MASANORI
IPC: G01B11/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor image-position detecting element which can reduce an image-position detecting error generated due to the influence of a noise light such as background light or the like by installing a resistance by which a photocurrent in a prescribed current density distribution over the whole region of a detecting section is subtracted from a photocurrent generated in a photoelectric layer. SOLUTION: When light is radiated from the surface side of a resistance layer RP, a photocurrent which is generated in a photoelectric layer in the incident position of the light flows into the resistance layer RP. The photocurrent which flows into the resistance layer RP is distributed according to a resistance value between a position in which the photocurrent flows into the resistance layer RP and a signal-current output terminal A and a signal-current output terminal B, and it is output as output signal currents IA, IB. Then, resistances rd by which a photocurrent in a prescribed current density distribution over the whole region of a detecting dection is subtracted from the photocurrent generated according to the incident light in every part of the photoelectric layer are connected.  Consequently, by the resistances rd, it is reduced remarkably that a photocurrent according to that generated due to noise light such as background light or the like flows into the resistance layer RP as a dividing resistance for image-position computing.

Title: Thermal recording material
Inventor: IKEDA HARUHIKO
IPC: B41M5/337
Filed: 1986-12-25
Abstract: PURPOSE:To obtain a thermal recording material having excellent heat response characteristics and high sensitivity, by incorporating a sepecified compound as a sensitizer in a thermal recording material comprising a normally colorless or light colored dye precursor and a color developer. CONSTITUTION:A compound of general formula (1), wherein each of Ar<1> and Ar<2> is an aryl, and X is O, S or an alkylene, is incorporated as a sensitizer in a thermal recording material. The compound of general formula (1) may be, for example, 2,5-diphenylfuran, 2,4-diphenylfuran, 3,4-diphenylfuran, 2,5- diphenylfuran, 2,4-diphenylthiophene, 3,4-diphenylthiophene, 2-phenyl-5-(4- chlorophenyl)furan or 1,3-diphenylcyclopentadiene. The sensitizer is ordinarily added in an amount of at least 5 wt.% based on the color developer, preferably, 10-400 wt.%, particularly, 20-300 wt.%. If the amount of less than 5 wt.%, a sensitivity-enhancing effect is insufficient, whereas an addition of more than 400 wt.% of the sensitizer may be inadvantageous on an economical basis, and due to the large amount of a heat-fusible substance, produces a diluting effect, so that a sufficient developed color density can not be obtained.

Title: Abnormal voltage protection device for ink jet printer
Inventor: OMORI HIDEYUKI
IPC: B41J2/12
Filed: 1987-12-10
Abstract: PURPOSE:To prevent ignition or electrical shock from being generated to abnormality in an electrifying signal voltage applied to an electrifying electrode, by providing a means for cutting off the electrifying signal voltage when a value in a timer means reaches a predetermined value and for informing of the condition. CONSTITUTION:When a clear input signal CLR is brought to a low level upon generation of an abnormal condition, a counter 34 becomes capable of operating. Since f/n-p clock signals are inputted as timer clock signals CLK of the counter 34, the counter 34 is increased each time the f/n-p clock signal is inputted. When the count on the counter 34 reaches n, an output signal Qn comes to a high level, an output signal NG-N from an inverter 35 is brought to a low level, and simultaneously, an output signal RY-N from an inverter 36 is brought to a high level. Thus, the abnormal condition is recognized. When the output signal RY-N is brought to the high level, a relay coil 20 is energized to turn OFF a relay contact 21, whereby supply of power to an electrifying amplifier 5 is cut off, thereby stopping generation of an electrifying signal voltage.

Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To obtain heat sensitive stencil printing original paper which is excellent in printing resistance by a method wherein water absorption of the original paper is made a specific % or under. SOLUTION: Heat sensitive stencil printing original paper is provided wherein in the heat sensitive stencil printing original paper composed of a thermoplastic resin film and a porous backing, water absorption of the original paper is 3% or under, preferably 2% or under, and further preferably 1.5% under. Since neither strength nor elastic modulus is lowered by moisture in the air and ink thereby, the original paper is neither deformed nor broken even though a great number of copies are printed. Therefore, strain or the like is not generated also in a printed image, and the original paper which is excellent in printing resistance can be obtained. Further, when the water absorption exceeds 3%, a drop of the strength and elastic modulus of the original paper is increased, and the printing resistance is deteriorated.

Title: Inserting method for electronic part based on guide pin recognition
Inventor: MIYAKE MASAFUMI
IPC: H05K13/08
Filed: 1993-12-13
Abstract: PURPOSE:To prevent erroneous insertion and achieve a high working ratio in the production of printed boards using electronic part inserters. CONSTITUTION:A visual recognition equipment judges whether guide pins for supporting the lead wires of an electronic part are properly projected through the electronic part insertion holes in a printed board (Step #5). Another visual recognition equipment judges whether the lead wires of the electronic part are properly supported by the guide pins (Step #6). If the above judgments reveals that the guide pins are not properly projected through a printed board or that the lead wires of an electronic part are not supported by the guide pins, then the lead wires are not clinched and the electronic part is discarded by a chuck tool (Steps #8, #9). If the guide pins are not projected through the electronic part insertion holes in a printed board, the insertion holes are detected again in the insertion position. Then the amount of deviation from the correct insertion position is detected to reduce variations in recognition accuracy of the recognition equipment (Step #10).
