Patent JP-S61255119-A (JP)
Title: Optical receiver
Inventor: TAMURA TOSHIJI
IPC: H04B10/556
Filed: 1985-05-07
Abstract: PURPOSE:To reduce remarkably pulse width distortion by providing a delay circuit retarding a threshold voltage for a prescribed time and a comparison circuit inputting a voltage from the delay circuit and a signal being electric conversion of an optical input and reproducing and outputting the signal. CONSTITUTION:The optical signal is converted into a current by a photodetector 1, converted into a voltage b an amplifier 2 and amplified into a waveform of a signal V4d1 required by a comparison circuit 9. An amplifier 7 generates a reference voltage when no optical signal exists. Since the output of a switching circuit 6 rises at the same time when the waveform of the signal V1 descends, the lower part from the center of the waveform of the signal V1 is sliced and then accurate waveform reproduction is not attained. Thus, a delay circuit 10 is provided after the switching circuit 6 and the entire thresh old voltage V2 is retarded from the waveform of the signal V1 so that a thresh old voltage V2' keeps the center position of the waveform of the signal V1 even if the waveform of the signal V1 descends, a pulse width distortion DELTATw' of an output voltage V3 outputted from the comparator circuit 9 is expressed as DELTATw'=t3-t2, and a signal with less distortion is obtained.

Title: Printer
Inventor: SUGIURA YOSHIO
IPC: B41J25/20
Filed: 1987-04-20
Abstract: PURPOSE:To enable an already printed character to be dressed later by providing a dressing key for instructing overstriking, and performing character dressing based upon the operation of said key, while providing a correction means for correcting the dressing data of a memory means. CONSTITUTION:When an operator moves a printing head M2 to a position where a character is already printed, and presses a dressing key M5, a correction means M6 performs a dressing on said character. The correction means M6 performs a correction on a dressing data of a character being contained in a character data relevant to a character in a memory means 1. By depressing the dressing key M5, a dressing data detection means M7 judges the presence of the character dressing data contained in the character data of the memory means 1 instructed by a pointer memory 4. When the judgement is 'YES', an overstriking means M8 does not perform overstriking for the dressing of said character, while when the judgement is 'NO', the means M8 performs overstriking only on the portion for dressing said character. By this operation, a character dressing can be performed even on a character already printed, thereby, a deviated overstriking can be avoided, and a well aligned character printing as compared with other printed characters can be obtained.

Title: Polyphase timing generator
Inventor: NISHIURA JIYUNJI
IPC: G01R31/319
Filed: 1982-06-07
Abstract: PURPOSE:To generate a timing of a desired phase with respect to many channels comparatively simply, by providing a mark memory in correspondence to each channel. CONSTITUTION:Mark memories M1-Mn of 1-2k having 1-bit storage capacity in each address are provided to each of channels CH1-CHn. A mark ''1'' is stored in the mark memories M1-Mn, and a counter 11 is advanced sequentially with a clock Tc when a reference timing Tp is given to a counter 11. This clock Tc is designated as a period of, e.g., 10nsec. When the timing to be generated on the channel CH1 is delayed to the reference timing Tp by 70nsec, the mark ''1'' is written in the 7th address 7 of the mark memory M1. Thus, the counter 11 is advanced and the count value reaches 7, then a mark is read out from the mark memory M1 and it is outputted to an output terminal 11as a generated timing. The timing of n phases is generated by two elements of the counter 11 and the mark memory 14 in this way. To change each generated timing, the stored address of the mark ''1'' in the mark memory of the corresponding channel has only to be changed and it is done simply.

Abstract: PURPOSE:To inexpensively obtain a color ink jet recorder simple in construction and small in size, by detecting the viscosity of one color ink, analogizing the viscosities of the other color inks, and pouring a diluting liquid into each ink tank. CONSTITUTION:Diluting liquid pumps 70 are driven through diluting liquid pump drivers 60 according to a detection signal from an ink viscosity sensor 50 provided between a pressurizing pump 20 and a nozzle 30 for a black ink (I), whereby a diluting liquid contained in a diluting liquid tank 80 is poured into each color ink tank 10 to control the viscosity of each color ink. For each of the color inks (II)-(IV), the quantity of the diluting liquid poured into the tank for the color ink is controlled in consideration of the difference in water evaporation rate between the color ink and the black ink (I). Namely, the pumps 70 are so driven that when the quantity of the diluting liquid poured into the tank for the black ink is assumed to be 1, those for the other color inks are set to be predetermined values of not more than 1. Accordingly, with the ink viscosity sensor 50 used for only one of the color inks, the viscosities of the other color inks can also be controlled, and the viscosities of the inks can be inexpensively detected.
