IPC: G03G15/08
Filed: 1994-10-26
Abstract: PURPOSE: To achieve the formation of a sharp toner image without soiling the surface of a photoconductor and its efficient transfer to a transfer material by means of electrical transfer by carrying out exposure from the back of the photoconductor, forming an electrostatic image by means of an electrode, which is opposite an exposing position, and developing the image by the use of insulated toner. CONSTITUTION: An electrostatic electrode is formed by a turnable photoconductive drum 1, an exposure means 9 for carrying out image exposure from the back of the photoconductive drum 1, and an electrode body (plate-like member) 8 having the electrode opposite the position where the photoconductive drum 1 is subjected to exposure by an the exposure means 9. This electrode body 8 is composed of a conductive member 81 related to the electrode, and a plate-like insulated member 82. In the position where the photoconductive drum 1 and the electrode body 8 abut on each other, an electric field is generated in advance, and the electrostatic latent image is formed on the part subjected to exposure from back by the use of the exposure means 9. A developing area is situated further downstream than the position where the electrode abuts on the image forming body.  In a developing area, development on a developing sleeve 2 is carried out with the insulated toner. Therefore, the toner image can be efficiently transferred to the transfer material by means of electrical transfer in the chargeless image forming device.

Abstract: PURPOSE:To obtain an inexpensive wafer scale semiconductor integrated circuit(WSI) of high density by adding or subtracting 1 to or from at least 1 bit of a 1st address signal for production of a 2nd address signal and outputting this 2nd address signal. CONSTITUTION:A 1st address signal is inputted to a 1st function block and 1 is added to or subtracted from at least 1 bit of the 1st address signal.

Title: Cvd apparatus
Inventor: KOBAYASHI HIDEO
IPC: H01L21/285
Filed: 1990-10-01
Abstract: PURPOSE:To enable the control of a distribution in heating temperature for a wafer on the top of a wafer stage by making the wafer stage from carbon graphite with an anisotropic crystal structure of orthogonality in a horizontal direction and parallelism in a vertical direction. CONSTITUTION:A wafer stage 7 is made from carbon graphite with an anisotropic crystal structure of orthogonality in a horizontal direction and parallelism in a vertical direction. That is, heat conductivity of crystal in a vertical direction is much smaller than that in a parallel direction: upon heating from below the wafer stage 7, most of penetrated heat thermally transfers in a vertical direction; therefore, a distributed state of heating the wafer stage 7 is reflected on a distributed state of temperature on the top of a after 8. This process uniformizes heat distribution of the wafer stage 7, thereby enabling uniform heating of the wafer 8.

Title: Carrier synchronization circuit
Inventor: SATO KAZUMASA
IPC: H04L27/38
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To prevent pseudo locking of recovered carrier in an orthogonal modulation demodulator. SOLUTION: A voltage controlled oscillator(VCO) 5 provides an output of a recovery carrier (g) whose frequency is controlled by a frequency control signal (f). A phase detector 1 applies synchronization detection to an orthogonal modulation wave (a) with the recovery carrier (g) to produce base band signals b1, b2. An identification device 2 identifies the base band signals b1, b2 to produce a demodulation main signal (c) and a digital signal (d) having phase difference information of the orthogonal modulation wave (a) and the recovery carrier (g). An APC signal detection circuit 3 generates an APC signal (e) corresponding to a phase difference between the orthogonal modulation wave (a) and the recovery carrier (g) based on the digital signal (d).  A DC level discrimination circuit 6 controls a switch circuit 4 with a DC level discrimination signal (h) and uses the APC(automatic phase control) signal (e) as a frequency control signal (f) when the APC signal (e) has a voltage within a prescribed voltage not causing pseudo locking to the recovery carrier (g) and uses a prescribed voltage V0 to be the frequency control signal (f) when the voltage of the APC signal (e) is at the outside of the prescribed voltage.
