Title: Pseudo halftone processor
Inventor: SHIBAZAKI KATSUYA
IPC: H04N1/40
Filed: 1991-11-28
Abstract: PURPOSE:To prevent the deterioration of the character images by converting the density of the noted picture element of an input image signal before the images are emphasized by an error diffusing method in order to emphasize the black/white contrast in the facsimile, etc. CONSTITUTION:The conversion of density is applied to an image signal 7 through a density converter circuit 1 so that the black/white contrast is emphasized. The output of this conversion is inputted to an adder circuit 2 and added to the weighted sum of an error calculated by a weighted sum calculation circuit 6. The output of this addition is binarized by a binarizing circuit 3 based on the binarizing threshold value 9. The output of the circuit 2 is inputted to an error calculation circuit 4 together with the binarized signal and a binarizing error is calculated. This error is stored at a position corresponding to the noted picture element stored in an error memory 5. This processing is carried out for each picture element of an entire image. Thus it is possible to prevent the deterioration of picture quality against the character parts when the characters and the photos are mixed together.

IPC: B01J23/20
Filed: 1993-12-15
Abstract: PURPOSE:To obtain matter semipermanently protected from fungi by exposing a semiconductive photocatalyst capable of optically decomposing fungi to the surface of the matter. CONSTITUTION:A semiconductive photocatalyst capable of optically decomposing fungi is exposed to the surface of matter. The semiconductive pohotocatalyst is titanium oxide or multiple oxides containing titanium oxide.

Title: Line thermal printer
Inventor: SAITO MASAMITSU
IPC: B41J2/32
Filed: 1988-12-14
Abstract: PURPOSE:To obtain constantly uniform print quality across the entire width of paper by providing an energization device which rotates and energizes a positioning member in a direction where a platen approaches a thermal head. CONSTITUTION:If a cover 23 is closed, both ends of a shaft 26 for a platen 27 are allowed to engage with the engagement sections 33 of a positioning member 31 respectively. Then both ends of the shaft 26 for the platen 27 are pressed toward a thermal head 24 because the positioning member 31 is rotated and energized clockwise by a spring 36. In this case, if holes which support both ends of the shaft 26 for the platen 27 are offset vertically, for instance, both ends of the shaft 26 can be shifted in a direction where the both ends get closer to and become isolated from the thermal head 24, due to a long hole 28. Consequently, the entire length of the platen 27 is pressed against the thermal head 24. Consequently, if paper 51A drawn out of a paper roll 51 is printed by allowing the paper 51A to pass between the thermal head 24 and the platen 27, print quality can be made uniform across the entire width of the paper 31A.

Title: Image pickup device
Inventor: HASHIMOTO SEIJI
IPC: H04N5/205
Filed: 1990-11-22
Abstract: PURPOSE:To obtain a picture with high accuracy by eliminating a high amplitude component in excess of a prescribed value of an image pickup signal and synthesizing a signal with less exposure from the image pickup signals so as to compress the high amplitude component. CONSTITUTION:When a luminous quantity to a sensor 103 is strong, a signal level of a signal S1 is saturated at a prescribed value. Then a black reference portion of the signal S1 is clamped by a clamp circuit 221 and the saturated part is clipped by a white clip WC circuit 222 and a high amplitude portion is eliminated. Moreover, a signal S2 of the sensor 103 is synthesized with the output signal of the circuit 222 via a sample-and-hold switch 216 by using a signal with less exposure than the signal S1 and the result is compressed by a KNEE circuit 231. Since the high amplitude component in excess of a prescribed value of the image pickup signal with large exposure is eliminated, noise is eliminated and a picture with high picture quality is obtained.

Abstract: PURPOSE:To shorten a recording time of a signal without lowering the detection accuracy of a time information signal. CONSTITUTION:At the time of sound recording, an R/P changeover switch (SW) 8 is switched to an R contact, and a sound signal from a microphone 5 is amplified by a preamplifier 6 and a power amplifier 7, sent to a head 9 and recorded on a tape 10. When a CUE mark SW 1 is depressed, a control part 2 detects it, and outputs a CUE signal and a TI signal to a pulse generation circuit 3 successively, and a sinewave is mixed with the sound signal from the power amplifier 7 through a waveform shaping circuit 4 and transmitted to a head 9 through the switch 8. At the time of reproducing, the SW 8 is switched to a P contact side, and the recording content of a tape is detected by the head 9 and outputted by a speaker 13 as a reproducing sound through the SW 8, the preamplifier 11 and the power amplifier 12. A reproduced signal through the preamplifier 11 is supplied to a filter 14, extracted with the component of only the CUE signal and the TI signal, converted into 'H', 'L' groups by a detector 15 and inputted to a control part 2. By operating an FF/REW 17, a recorder is made a FF or REW reproducing state.

Title: Work holding device
Inventor: KASAHARA TSUKASA
IPC: B23B31/16
Filed: 1987-12-16
Abstract: PURPOSE:To permit the automatic catching of a work such as glass rod by comparing the turning angle detected up to the stop of a chuck turning rotary machine and a set value and detecting if a work is caught by a chuck independently of the work diameter. CONSTITUTION:A comparator 10 receives a work installation signal from a controller 13 and revolves a torque motor 3 from a perfect opened hook position and receives the pulse quantity up to the stop due to overload and performs integration calculation. At this time, the stop of the motor 3 is judged by detecting that no pulse is received from an encoder 4 for a certain time. Then, the integration pulse is compared with a set value on a setting device 11 accord ing to the size of a work, and if judged to be in accord, the power source for the motor 3 is cut off, assuming that a chuck 1 catches a work, and a signal for carrying out the next operation is transmitted. If the integration pulse is larger than the set pulse quantity, it is judged that the work is not correctly mounted onto the chuck 1, and an anomaly alarm device 12 generates an alarm, while if the detected pulse quantity is smaller than the set value, it is judged that the chuck 1 is restrained, or a foreign material is caught, and an alarm is generated.
