Title: Data transmission system
Inventor: ITSUGAYA KINJI
IPC: H04Q9/00
Filed: 1988-05-19
Abstract: PURPOSE:To rapidly inform a data delivery request to a master station device by constituting the title system of a synchronous flag, a data transmission request flag, an address part, a control part, a data part, and a frame check sequence part. CONSTITUTION:Data transmission between the master station device M1 and a slave station device designated at the address part A is performed by the address part A, the control part C, and the data part D. For example, when the master station device M1 sends the frame of the address part A setting at '1' and that of the data transmission request flag DSRQ at '0' the slate station S1 responds to them. And assuming that the slave station SN issues a transmission request while the frame is returned again to the master station device M1, the slave station device S2 having no data transmission request relays the DSRQ, and the slave station device SN having the data transmission request sends the DSRQ as '1'. In such a way, the master station device M1 can detect the data transmission requests issued from one or more slave station devices when the DSRQ of a returned frame is set at '1'.

Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To easily estimate tristimulus values under an optional light source by measuring a printed color chip with a plurality of illumination lights and approximating the measured result to a color when an actual illumination light illuminates the color chip. SOLUTION: A plurality of color chips are printed out, and illuminated with a fluorescent lamp generating near ultraviolet rays to excite fluorescent substances. The excited component is measured. The excited component is measured with an illumination light including ultraviolet rays large and an illumination light including ultraviolet ryas little. Colorimetric values (spectral reflectances) 1 and 2 are inputted by a memory 10. The memory 10 stores a coloring data 11 essentially of a fluorescent component by the near ultraviolet rays and a coloring data 12 essentially of a pure reflectance and, outputting as spectral reflectances Rf (λ) and Rn (λ).  A weight mean operation part 20 to which the spectral reflectances are inputted has an input of an intensity L of a possible color light part of an observation light source from illumination light information, and obtains a spectral distribution by an approximation calculation from the inputted data. Tristrimulus values are calculated from the obtained spectral distribution. Tristimulus values under an actual light source can be simply estimated accordingly.

Title: Electrostatic recording device
Inventor: SHIMIZU HARUO
IPC: G03G15/04
Filed: 1981-08-04
Abstract: PURPOSE:To prevent the occurrence of jamming and to form an image of good quality by generating a signal for indicating the position of transfer paper to a recording body, and inhibiting an image signal according to the signal. CONSTITUTION:The transfer of image signals through signal lines SL1 and SL2 is started by a vertical synchronizing signal SL7. In this case, image writing signals A and B are generated and sent from an internal control circuit 9 through a signal line SL3. Once the signal A appears, the image signals are inhibited from passing through gate circuits 10 and 11 in a prescribed section, so that image signals are not generated on a photosensitive drum. The signal B, on the other hand, is generated in response to a transfer end signal to inhibit the recording of image signals between transfer paper and transfer paper and in a prescribed section of the front edge part of the next transfer paper. During the period of this signal B, laser on signals appear through signal lines SL5 and SL6, and consequently a light and a dark part potential are generated to control the surface potential of the photosensitive drum.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent the heat generation of a stabilized transistor by connecting a Zener diode between the input side and output side of the stabilized transistor connected to an overcurrent protective element on the input side. SOLUTION: The Zener diode D2 is connected between the collector and emitter of the stabilized transistor Q1 connected to an IC protector IC1 functioning as the overcurrent protective element on the input side. In this case, the output voltage of the IC protector IC1 is defined as V1, the emitter voltage of the stabilized transistor Q1 is defined as V2, and when a load L2 is short-circuited, since the both-terminal voltage of the Zener diode D2 becomes V1 and exceeds a Zener voltage, the Zener diode D2 is turned to a short-circuit state, the emitter side of the IC protector IC1 is interrupted and functioning is performed as a protective circuit. Thus, the heat generation of the stabilized transistor Q1 is prevented.
