IPC: G01N21/3559
Filed: 1988-04-28
Abstract: PURPOSE:To measure the characteristics such as moisture content of a sheet material even on site of high-temp. use environment by cooling upper and lower heads for IR irradiation which form the traveling space of the sheet material by heat sinks of a rectangular parallelepiped shape having release fans of required constitution. CONSTITUTION:The sheet material travels in the spacing formed of the upper and lower heads which are disposed to face each other and irradiate IR rays. The moisture content, etc., of the material are thus measured. The upper and lower heads are respectively well cooled by the heat sinks 11a, 11b of the approximately parallelepiped shape which have the release fans 12a, 12b and are cooled by the water flowing in copper pipes 10a, 10b.

Title: Printing device and plot processing method therefor
Inventor: TODA MASANARI
IPC: G06T11/60
Filed: 1994-05-20
Abstract: PURPOSE:To produce high-resolution output in printing image information which contains a large multivalued color image data directed by a page descriptive language. CONSTITUTION:When a CPU 9 analyzes a color page descriptive language to be inputted and determines a multivalued color image data, an index color converting hardware 41 converts a multivalued color image source data based on the page descriptive language into an intermediate language to be directed by a multivalued color index data which is previously registered in a memory means. In generating a plotting data, the converted intermediate language is restored to an output data approximate to the multivalued color image source data by referring to the multivalued color index data at the CPU 9. In accordance with the restored output data, a hard renderer 42 plots and expands the plotting data in a RAM 5. The expanded plotting data is printed by a printer engine 10.

Title: Duplex computer system
Inventor: SAGARA TATSUO
IPC: G06F15/16
Filed: 1985-05-20
Abstract: PURPOSE:To fetch completely the input information obtained from each computer system by supplying continuously the input information distributed to each computer system through a distributor for a period longer than the input processing cycle of each computer system. CONSTITUTION:A distributor 1B secures the self-support of an input amplifying relay RYA which receives the input information and releases said self-support by means of a timer TA. The set time T2 of the time TA is longer than the input processing cycle time T1 of A and B computer systems. As a result, both computer systems can read the input information completely even with the pulse width smaller than the time T1. Therefore the discordance between output signals is completely eliminated.

Title: Developing method of two-color electrophotographic device
Inventor: KOBAYASHI SHIYOUICHI
IPC: G03G13/01
Filed: 1984-05-29
Abstract: PURPOSE:To enable a sharp 2-color electrophotograph to be obtained by selecting a carrier to be used for the first developing device for developing the second color image signal having a high resistivity higher than the ordinary carrier by about 20 times. CONSTITUTION:A carrier high in resistivity is used for the carrier 12 of the first developing device 7, the electrostatic charge on the surface of a photosensitive body 1 is prevented from leaking through the carrier 12, and the curve (c) does not decend so much toward the side of the curve (f). Then, the photosensitive body 1 undergoes whole uniform exposure from a uniform exposure device 8. The area not exposed to the first color image signal is converted into a potential, as shown by the curve (e), and only the area exposed to said image signal becomes a negative side potential, as shown by the curve (f). Therefore, the potential difference between the latent part of the first color and the background can be enlarged, as shown by the curves (f), (c), and (e), and the first color toner positively charged with the second developing device 9 is attached only to the negative potential part of the photosensitive body 1, thus permitting a sharp 2-color image to be formed.

A microprocessor 610 exchanges data between a RAM 608 and the UART 606. An HDLC controller 616 adds DLCI based on information outputted from an LID controller 614 to form an HDLC frame to be sent to an FRYPAM. On the receiving side, information on an input line is physically converted into data consisting of a signal CLK and the HDLC to interface with a specific data terminal in the system.

Title: Automatic gain control circuit
Inventor: NAKAMA SEIJI
IPC: H03G3/20
Filed: 1982-06-23
Abstract: PURPOSE:To obtain a circuit which operates stably regardless of temperature fluctuations and variance of elements without adjustment by using a variable impedance element or circuit which varies in impedance with the output voltage of a smoothing circuit. CONSTITUTION:A signal inputted to an input terminal 1 is amplified by an amplifier 3 and outputted to an output terminal 2. A part of this output is inputted to the plus terminal of a comparator 12. A reference voltage is applied to the minus terminal of the comparator 12, whose output is applied to the base of a transistor (TR) 10 through the smoothing circuit 5, but the resistance of the TR10 decreases as its base voltage rises. Thus, the resistance of the TR10 decreases and the input level attenuates at the ratio to a resistance 11 to decrease the output of the amplifier 3. At the time, the output of the comparator 12 turns into a minus voltage once the output level of the amplifier 3 drops below the reference voltage to return the initial state again. The output of the amplifier 3 is applied to and monitored by the comparator 12, so a stable output is obtained regardless of temperature fluctuations and variance of elements.
