Title: Non-contact drying method
Inventor: OZAKI KOJI
IPC: G03C1/74
Filed: 1992-05-11
Abstract: PURPOSE:To stably feed a web while preventing the curling thereof by injecting air from a blowoff port to support the continuously running web and coating the end parts of the rear of the web whose single surface is coated. CONSTITUTION:In a non-contact feed device supporting a continuously running web by injecting air from a blowoff port, when a coating solution is applied to the opposite surface of the web whose single surface is coated with the coating solution, the coating solution is not applied to the web over the entire width thereof in general in order to prevent the transfer of the coating solution to the rear of the web and slight uncoated parts are usually left on both ends of the web. In this case, the coated part and uncoated part of the web are extremely different in the penetration degree of the coating solution and a curl is generated in the web. In order to prevent the curling of the web, in the case of the coating of the single surface of the web, both end coating is applied to the surface opposite to the coated surface of the web, that is, the parts where curling is especially strongly generated on both sides of the web to form curling-preventing coating layers 3.

IPC: H04L7/033
Filed: 1989-05-10
Abstract: PURPOSE:To prevent the frequency of an output clock from varying by connecting two diodes to the feedback path between the input and output of an amplifying circuit in parallel so that the polarities are opposite. CONSTITUTION:The output signal of a phase comparing circuit(PC) 3 which inputs an external clock inputted from a terminal 1 and an output clock from a terminal 2 is supplied to the input terminal of an inverting amplifier 4, a resistance 7, the anode of a diode 8, and the cathode of a diode 9. Further, the output signal of the inverting amplifier 4 is inputted to a voltage-controlled oscillation circuit (VCO) 5 and supplied to the resistance 7, the cathode of the diode 8, and the anode of the diode 9, and the output signal of the voltage- controlled oscillation circuit 5 is outputted from the terminal 2. Thus, the diodes 8 and 9 are connected to the feedback path of the amplifying circuit in parallel in the opposite polarity state and the output amplitude of the amplifying circuit is suppressed to the voltage drop across the diodes to suppress the variation in the frequency of the output clock of the voltage-controlled oscillation circuit.

Title: Optical displacement detector
Inventor: TOSHIKAGE HIDEKI
IPC: G11B7/09
Filed: 1984-06-08
Abstract: PURPOSE:To obtain an optical detector which can be easily assembled by detecting no change of the incident angle by the optical detector and detecting the intensity itself of the focused light sent from a hologram to detect the displacement and its direction of an object to be detected in the direction of the optical axis. CONSTITUTION:It is first decided whether the outputs of the light detecting parts 7a and 7b are maximum or not when the focus control is performed in an action mode of an optical disk 5. When these outputs are not maximum, the shift direction of a lens 4 is decided according to the levels of outputs of light detecting parts 7c and 7d compared with the reference value. In this example the change of the incident angle of the light 2 is not detected directly by an optical detector 7. Instead the detector 7 detects the intensity itself of the focused light sent from a hologram set on a recording medium 6. Therefore it is not needed to set the detector 7 with extremely high accuracy. This facilitate an easy assembly of a light detector with a small position shift due to a secular change.

Title: Compression method for picture information
Inventor: MATSUI NOBUHIKO
IPC: G06T5/00
Filed: 1990-05-08
Abstract: PURPOSE:To compress a multi-color digital picture to a picture with the small number of quantization bits through a stage compressing a picture element of (m) bits to (n) bits, a stage diffusing quantization error, a correlation-degree calculation stage with an ambient picture element, and an error distribution stage. CONSTITUTION:8 bit elements composing of a digital picture 10 of a color space A are inputted to a comparator 12, and stored in a memory 14 by compressing into 3 bits data 0-7 by comparing them with seven threshold values. At the time of the conversion by compression, the quantization error is calculated by a subtracter 16 to store it into the address corresponding to an ambient picture element 10b of an attention picture element 10a of an error diffusion memory 18. This quantization error is added through an adder 20 at the time of compressing the picture element 10b. In a correlation-degree calculator 22, the correlation of attention elements 10a and 11a of the color space A and B and the ambient picture elements is determined, and a multiplicator 24 multiplies the input correlation-degree as weighting by the output of the subtracter 16 to output the quantization error corresponding to the correlation-degree of the color spaces A and B to the other color spaces. Thus, high- quality picture with good color slurring can be obtained while recognizing the change of color.
