Title: Grid bias circuit
Inventor: KONAKA MIKIO
IPC: G03G15/00
Filed: 1991-03-01
Abstract: PURPOSE:To maintain the best drum current at all times even if circumference conditions of temperature, etc., are changed so that a drum current can be held at a specific value, to secure the excellent picture quality performance of a copy, and to improve environmental resistance. CONSTITUTION:When the drum current Id increases above a specific value, the potential of a photosensitive drum 30 which is detected by the potential sensor of a voltage control means 22 becomes high. An external control voltage Vc applied with a detection signal corresponding to the potential of the photosensitive drum from the potential sensor 24 becomes high as the potential of the photosensitive drum 30 increases and is applied to a variable constant voltage circuit 12. Then a grid current Ig increases and the drum current Id decreases because of a relation Id=Ih-Ig and returns to its original specific value. When the drum current Id decreases below the specific value, on the other hand, reverse operation is performed and the grid current Ig decreases, so the drum current Id increases and returns to its original specific value.

IPC: H04L1/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To improve the transmission efficiency for the entire radio communication system while conducting proper error check and correction corresponding to a reception state. SOLUTION: A quality discrimination section 3 discriminates quality of received data Sr and a selection signal Sc1 corresponding to the discrimination result is generated and sent to an opposite communication equipment. The communication equipment receiving the selection signal Sc1 uses a switch 9 to separate the selection signal Sc1 from the received data Sr and selects whether a high capability code generating section 11 is used for accurate and sure communication or a low capability code generating section 121 is used for communication with a high transmission rate based on the selection signal Sc1 . Thus, proper error check correction capability is selected depending on the communication quality and the transmission efficiency is improved.

Title: Phase modulator
Inventor: ARAI MEGUMI
IPC: H04L27/20
Filed: 1980-03-24
Abstract: PURPOSE:To reduce a transmission power loss with relatively simple constitution by providing a phase shifter in a path which includes a phase modulator. CONSTITUTION:For the operation of a two-phase modulator, main switch SW is closed to apply the output signal of switching signal source PSS to phase shifter PS and change-over switch TSW, and the phase shift angle of phase shifter PS is set to 90 deg. to equalize digital signals supplied to two modulators MOD1 and MOD2. Therefore, since output signals of both the modulators are in phase with each other in this case, signals of paths PTH1 and PTH2 are superposed mutually when mixed by the 2nd hybrid circuit HB2 to reach output terminal OUT. Consequently, the power loss is only 3dB in the 1st hybrid circuit HB1 and 3dB less than that of a four-phase modulator.
