IPC: G03G15/04
Filed: 1983-06-24
Abstract: PURPOSE:To perform image formation with high reliability by providing a means which detects an original size and a means which detects the scanning position of an original exposure scanning system, and making an exposure scan on an original on the basis of detected signals from those means.

Title: Handy printer
Inventor: CHIBA NORIYOSHI
IPC: B41J2/485
Filed: 1987-05-11
Abstract: PURPOSE:To make an image printable without elongation and to make the distortion of the image attributed to a reverse sub-scanning preventable, by counting a line address in a frame memory in synchronism with an encoder. CONSTITUTION:If a pulse signal 109 from an encoder 102 is detected before a line thermal head thermal head 101 completes one-line printing, 1 line address 111 is counted from (n+1) to (n+3) by a line counter 105. Therefore, the data in a frame memory 103 is skipped. If a sub-scanning direction position on a plain paper is detected by the encoder 102, the data in a line address (n-1) is printed on a position (n). If the pulse signal 109 of the encoder 102 is skipped by a gate 301, a blank is generated on the plain paper. However, because the data on the frame memory 103 is also skipped corresponding to the blank, the elongation of an image can be prevented. furthermore, a distortion of an image can be prevented also in a reverse sub-scanning by a method wherein a decrement of a line address is allowed by making the encoder capable of detection also in a rotating direction.

IPC: H01L21/302
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To produce an electrode plate for plasma etching low in generation of fine particles and made of a glassy carbon by forming from the glassy carbon in which a surface roughness of a breaking surface structure has a structural property within a specified range. SOLUTION: In an electrode plate for plasma etching, the surface roughness Rms of a breaking surface is used as a measure indicating the fine structural structure of a glassy carbon and this value is set within the range of 5-30 nm. The range of 5-30 nm of the surface roughness Rms of the breaking surface is characterized in that an amorphous carbon crystal structure being a material characteristic of the glassy carbon has a structural property within a fixed range. When the value of the surface roughness of the breaking surface is lower than 5 nm. resistance to the plasma is lowered and a consumption speed at the time of etching is increased since a developing degree of the fine structural structure is low and an intercrystaline structure is small, on the other and, when the value exceeds 30 nm, a structural unit of the fine structure becomes large and the development of the particles accompanying the consumption is increased.

Title: Vacuum plating device
Inventor: OONISHI YOUICHI
IPC: C23C14/24
Filed: 1981-07-22
Abstract: PURPOSE:To stabilize the evaporating surface of a crucible and to form a vacuum plating layer uniformly on the surface of a material to be plated by providing a cover consisting of a foamed metallic plate on the evaporating material side of an auxiliary facility for protecting the material to be plated against the heat of the evaporating material. CONSTITUTION:In a vacuum vessel 1, the vapor of the molten metal in a crucible 5 is vapor deposited by an ion plating method, etc. on a material 2 to be plated. Since a cover 6 is of a foamed material, the heat conduction in the contact part with the surface of a cooled auxiiliary facility 3 is small and therefore the surface temp. thereof rises sharply after the start of the vacuum plating. Then strong adhesive force is generated at the interface between the surface of the cover 6 and the vapor deposition layer accumulated thereof. As a result, the dropping of the materials accumulated on the surface of the cover 6 on the evaporating surface 5a of the crucible 5 is difficult to occur, and the metallic vapor distribution on the evaporation surface 5a can be stabilized for a long time. The deformation over the entire part of the cover 6 is small, and the vacuum plating operation is carried out continuously and stably for a long time.

CONSTITUTION:The voltage V1 of a high voltage circuit 10 is put on an electrostatic charger 3 and the potential E1 formed on the surface of a rotating photosensitive drum 1 is detected by a surface potential sensor 6. Next, the surface potential E2 at the time of varying the voltage of the electrostatic charger to V2 is measured and at the same time the photosensitive drum 1 is stopped. The voltages V1 and V2 and the potentials E1 and E2 are stored in a CPU. The rotation of the drum 1 is stopped for DELTAt seconds in such a state. The length of DELTAt seconds is a time necessary for the rotation of the surface part of the drum 1 from a position facing to the sensor 6 to the developing part 5' of a developing device 5. The potential E3 at such a time is measured by the sensor 6. The CPU calculates the ratio B of the difference between V2 and V1 to the difference between E2 and E1 and dark attenuation amount obtained for DELTAt seconds A=E2-E1. Therefore, the optimum electrostatic charging voltage to obtain a desired potential in the developing part 5 can be obtained.
