Title: Electrophotographic printing device
Inventor: SUGAYA HIROSHI
IPC: B41J2/44
Filed: 1989-05-31
Abstract: PURPOSE:To improve vibration-proof property by adopting a honey-comb structure for a panel mounting an optical part. CONSTITUTION:A gas laser oscillator 2 in which He and Ne are sealed continuously oscillates, and an emitted laser beam 12 passes through prisms 3 and 3', is adjusted to a proper beam diameter by a series of lens groups 5. It passes through an SV lens 7, enters a polygon mirror 8, and then focuses on an image plane via an ftheta lens 10. This optical system has to be composed with extremely high precision. If the vibration caused by a mechanism part (not shown here) is given to an optical system panel 1 where the optical part is mounted, the path of the laser beam 2 is turbulent and a precise image is not obtained. Therefore, the optical system panel 1 is made of a honey-comb material, so that the influence of the vibration caused by the mechanism part is reduced by making use of its vibration damping effect.

Abstract: PURPOSE:To obtain the high-quality electrolytic copper foil uniform in thickness in the cross and longitudinal directions, by forming a part of an electrode as the plural split foil thickness uniformizing anodes and separately controlling the quantity of electricity to be supplied to each anode. CONSTITUTION:A cathode drum 1 as a rotary cylinder is partially dipped in an electrolyte and confronted with at least one circular insoluble anode 3.

Filed: 1986-06-18
Abstract: PURPOSE:To attain the stop of intermittent reception by a succeeding signal by detecting a signal at the intermittent reception while counting a change point signal of a received data signal at the inside and outside of a window signal synchronously with a synchronizing clock signal and comparing the quantity. CONSTITUTION:A decoder 30 outputs an intermittent reception control signal such as a synchronizing clock signal and a window signal based on a clock signal of a clock generating circuit 40. Then a radio reception section 20 receives a modulated radio signal from an antenna 10 and outputs a demodulated digital signal to the decoder 30. The decoder 30 decides whether or not the signal is a standby signal through the detection of the signal representing the intermittent reception. In deciding the signal as the standby signal, the intermittent reception is stopped to await the succeeding synchronizing signal. In detecting the synchronizing signal, the word synchronization of a signal string is established, then the address signal of the said signal string and one's own identification signal set in a number setting section 50 are comapred and collated at a prescribed timing. When they are coincident, a ring tone signal is outputted and a ring tone is outputted from a speaker 70.
