Title: Tone detection circuit
Inventor: AKAGI YOZO
IPC: H04M11/00
Filed: 1990-04-19
Abstract: PURPOSE:To prevent malfunction due to a harmonic component of a 400Hz tone signal by stopping the transmission of a detection signal of a 2100Hz component signal when a detection output level of a 400Hz signal component is higher than a detection output level of the 2100Hz signal component. CONSTITUTION:A tone signal is inputted respectively to 2100 and 400Hz band pass filters 12, 13, from which 2100 and 400Hz signal components are respectively extracted and each of the extracted signal components are detected respectively by detection circuits 14,15. A level comparator circuit 20 receives and compares the detection outputs from the detection circuits 14, 15 respectively, compares them at when the detection output level of the 400Hz signal component is higher than the other detection output level, a control signal is generated and it is sent to a level detection circuit 16. Upon the receipt of the control signal from the level comparator circuit 20, the level detection circuit 16 stops the detection and does not send a 2100Hz detection signal. Thus, even when the attenuation characteristic of the band pass filters is insufficient, malfunction is prevented.

Title: Lithographic original plate forming method
Inventor: YASHIKI YUUICHI
IPC: G03F7/075
Filed: 1979-08-16
Abstract: PURPOSE:To easily obtain a lithographic original plate requiring no dampening water by coating a support with a photosetting resin having ink repellency, imagewise exposing the resin layer, and washing the unexposed portion with solvent. CONSTITUTION:Support 1 such as paper, a plastic film or metal foil is coated with a photosetting resin based on epoxy acrylate resin, polyisocyanate and alcohol- modified silicone oil to form resin layer 2. Layer 2 is imagewise exposed and washed with solvent. Since exposed portion 2A is solidified by polymn. and converted into a solvent resistant coat, it remains after the washing, and unexposed portion 2B is washed away. Thus, a lithographic original plate is formed. The set resin coat is ink repellent, so printing ink sticks to a portion corresponding to the unexposed portion alone, and a positive image can be printed.

IPC: H01L27/10
Filed: 1986-05-09
Abstract: PURPOSE:To realize a high-speed, reversible data storing memory device by a method wherein a lamination constituting a data storage is illuminated with electromagnetic waves for the accomplishment of memorizing, reading, and deleting. CONSTITUTION:A data storage of this design is constituted of carrier generating layers 1 and 2, charge storing layer 3 sandwiched between the carrier generating layers 1 and 2, and electrodes 4 and 5. Memorizing electromagnetic waves 7 are projected from the electrode 4 with the electrode 4 set positive against the electrode 5, which causes hoes 8 and electrons 9 to be generated by excitation in the carrier generating layer 1. The electrons 9 flow out of the electrode 4 but the holes 8 remain trapped in the charge storing layer 3. For reading, connection is switched from a battery 6 to an ammeter 10, for the projection of reading electromagnetic waves 11. Holes 12 and electrons 13 are generated by excitation in the carrier generating layer 2. Owing to the internal electric field, the holes 12 flow toward the electrode 5 and electrons 13 flow into the charge storing layer 3 for combination with the holes 8 trapped therein. In this process, a current flows in an external circuit, which drives the ammeter 10 to indicate that data was within.

Abstract: PURPOSE:To prevent a white part from becoming dark and to form an easily seeable copied image in the case of densely copying an original having light density by reducing the variation of a voltage impressed on an exposure means as to a part having darker density with reference to the variation of a set density. CONSTITUTION:As to the relation between a density setting scale installed in a density setting means 2 and the voltage of a halogen lamp, the variation of the voltage of the halogen lamp is made gradually small as compared with the variation of the scale on the side having scales smaller than the scale of the center part (the side where the copying density is made dense). In the case of copying the original having light density, the copying density is set dense by a density setting means 2. A control signal is outputted to an AVR circuit 5 by a CPU circuit 4. The voltage corresponding to the density setting scale is impressed on the exposure means (halogen lamp) 1 by the AVR circuit 5. Thus, the white part (base color) does not become very dark and the image density on the character part is made dense, so that the easily seeable copied image is obtained.
