Title: Jam error detecting method
Inventor: MOMOSE MASANORI
IPC: B65H7/06
Filed: 1985-11-30
Abstract: PURPOSE:To detect the erroneous feed of a document, by a method wherein the length of a document passing a document reading position sensor is compared with the size of the document. CONSTITUTION:During reading motion of a document reading position sensor 8, a counter is subtracted each time one pulse driving of a driving pulse motor 7 is effected. Since the counter is set to a document length + alpha, wherein alphais a factor considering unevenness in a sheet, a document feed error and the like, when counter is subtracted each time one pulse driving of the driving pulse motor 7 is effected, when passage of the terminal end of a document 1 in a document reading position sensor 8 for the set document is confirmed, the counter is reduced to zero. Thus, when the counter is reduced to zero before confirmation of passage of the document 1 through the reading position sensor 8, the size of the document 1 under passage is longer than that of the specified document set on a document stand 2 by a document size sensor 15. In this case, it is decided by the sensor that a jam error occurs.

Title: Ant-controlling sheet material
Inventor: WADA TAKAO
IPC: E04B1/72
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To provide an ant-controlling sheet material enabling the easy safe performance of an ant-controlling treatment without accompanying a work such as coating or spraying an ant-controlling agent by coating a synthetic wax or a natural wax which is compounded with an ant-controlling agent on one side or both sides of nonwoven fabric made of nylon, etc. SOLUTION: A coating material is prepared by adding an agent having an ant-controlling activity to one or more than one selected from paraffin wax, beeswax and Japan tallow and fusing the mixture, and it is coated on at least one side of nonwoven fabric 2 made of a synthetic resin to form ant-controlling agent layers 3, 3'. In the ant-controlling layers 3, 3' of the ant-controlling sheet material, the ant-controlling agent exists as fine particle whose periphery is coated with a membrane of a wax, and the agent evaporates slowly. This allows the activity of the agent to last for many years. By cooling, the ant-controlling agent layer 3, 3' becomes a solid state having surfaces consisting of scaly crystallines, and the layer is imparted with air permeability and moisture permeability.  Since the nonwoven fabric layer 2 has same kind of properties, the obtained ant-controlling sheet is excellent in air permeability and moisture permeability.

Title: Photoacoustic cell
Inventor: OYA AKIRA
IPC: G01N29/00
Filed: 1990-10-05
Abstract: PURPOSE:To obtain a photoacoustic cell setting off external vibration effect, reduced in output noise and enhanced in an S/N ratio by arranging two condenser microphones in opposed relationship and providing an adder circuit adding the output signals of both microphones. CONSTITUTION:A sample 15 is irradiated with light interrupted and throttled at fre quency (f) through an optical window 11. A part of the light is reflected from the surface of the sample 15 and the remainder is absorbed in the sample 15 to be converted to heat to diffuse throughout the sample 15 and, since a part of the heat allows the air on the surface of the sample 15 to expand, the pressure in a sample chamber 14 is raised to generate a photoacoustic wave. At this time, the vibration membranes of condenser microphones 12a, 12b are displaced in the same phase and the outputs of preamplifiers 13a, 13b become the same phase to be added by an adder circuit 16 to become an output signal. When external vibration is applied to an photoacoustic cell, the displacement becomes an inverse phase and the outputs of the preamplifiers 13a, 13b are added and set off by the adder circuit 16 and the output signal of the circuit 16 becomes zero and does not change against external vibration. By this method, the output noise due to the external vibration is reduced and an S/N ratio can be increased.

Title: Image display device
Inventor: SEKIGUCHI TOMOHIRO
IPC: H01J31/12
Filed: 1988-10-26
Abstract: PURPOSE:To enable an image of high quality to be obtained by meshing conductive plates in a sinking comb shape with each other via space, which are projected to the direction normal to the figure from two reinforcing bars in a sinking comb shape of a horizontal deflection electrode, and thereby concurrently forming the end surfaces of the reinforcing bars in a sinking comb shape into a saw-tooth shape. CONSTITUTION:A horizontal deflection electrode 32 is composed of two reinforcing bars 40 and 41 which are meshed with each other in a same plane to the direction horizontal to the figure via space. In addition, conductive plates 42 and 43 which are projected to the direction normal to the figure from two each of the reinforcing bars 40 and 41 in a sinking comb shape, are meshed with each other via space, and the extended end surface of the conductive plates 42 and 43 of the reinforcing bars 40 and 41 in a sinking comb shape are formed into a saw-tooth shape. Which, therefore, enables the distance between the reinforcing bars 40 and 41 in a sinking comb to be made wide so that the vertical deflection effect of a horizontal deflection electrode 32 can be make small. As a result, which situation can prevent driving voltage wave form at each place 33A through 33B of vertical deflection electrodes from being complicated in order to correct the vertical deflection effect of the horizontal deflection electrode 32. By this constitution, an image of high quality can thereby be obtained.

Abstract: PURPOSE:To stably print even a large-sized paper continued on a small-sized paper with high image quality by controlling the adjustment of the emitting light quantity of a destaticization means so that it becomes more than normal irradiating light quantity on the circumferential surfaces of both sides of an image carrier except the circumferential surface corresponding to the width of a paper for detection. CONSTITUTION:When the small-sized paper Ps is detected by a paper width detection means 20 (optical type sensors S1-S3), an adjustment signal CNT based on the detection signal S is outputted by a control means for adjusting the increase and decrease of emitting light quantity 30 and all the destaticization lamps L1-L15 of the destaticization means 17 are turned on. Therefore, the circumferential surface corresponding to the width dimension of the paper Ps of the image carrier 11 is irradiated with the normal light quantity from the lamps L7-L9 disposed by double pitches and destaticized. However, the circumferential surfaces of both sides except the circumferential surface corresponding to the width dimension are irradiated with the light emitted from the lamps L1-L6 and L10-L15 disposed by the small fixed pitch. That means, the circumferential surfaces of both side are irradiated with much light quantity. Therefore, the circumferential surfaces of both sides directly transferred and electrostatically charged by a transfer device 15 are also uniformly destaticized to a prescribed level by much light quantity.

Filed: 1984-12-21
Abstract: PURPOSE:To make the output potential of a differential amplifier circuit and the amplification factor constant independently of a power supply voltage, a change in a resistance due to temperature and the absolute accuracy of resistors by flowing a current flowing to an emitter follower constituting a current mirror circuit deciding a current value flowing to the differential amplifier circuit to a resistor and applying feedback so as to make the voltage generated across the said resistor equal to a reference voltage thereby deciding the current. CONSTITUTION:A current flowing to a transistor (TR) Q1 depends on a base potential of the TR Q1 and a resistance of a resistor R2. Further, a current flowing to the TR Q1 flows the resistor R1, across which a voltage is generated. The 2nd differential amplifier circuit 12 compares a voltage generated across the resistor R1 with a reference voltage (Vref) from a reference voltage generating circuit 11 so as to adjust the base potential of the TR Q1 to be equal to each other. Since the same potential as that of the TR Q1 is given to a base of a TR Q4 having the similar characteristic to that of the TR Q1. Thus, a voltage V6 generated across resistors R2, R4 with Vin<+>=Vin<-> is expressed in equation I. When the resistance ratio of R2/R7 and R3/R1 is constant, the voltage V0 is kept always constant.
