Title: Method and apparatus for making dot patterned plate
Inventor: BUINRITSUHI GARU
IPC: H04N1/405
Filed: 1984-11-14
Abstract: In a method and apparatus for producing half-tone printing forms with screens having arbitrary screen angles and screen width, screen dots are exposed on a recording medium by means of a recording element whose exposure beam is switched on and off by a control signal. The recording medium is sub-divided into a plurality of areal elements which are exposed or not exposed by the exposure beam as a function of the control signal. All areal elements exposed in a screen mesh of the rotated screen to be recorded form a respective screen dot. At least two matrices in the form of matrix memories are provided, the individual matrix elements thereof having screen threshold values allocated to them. The screen threshold values forming a screen hill represent the periodic basic structure of a screen mesh and are different for at least one tonal range in the individual matrices. During recording, those matrix elements in the individual matrices whose positions within the respective matrices correspond to the positions of the swept areal elements within a screen mesh are identified. The screen threshold values of the identified matrix elements are called in. Controlled by a random generator, one of the called screen threshold values is randomly selected and compared to an image signal value acquired by means of scanning an original. The control signal for the exposure beam is derived from the comparison, whereby a decision is made on the basis of the signal comparison as to whether the corresponding areal element is to be exposed or not as part of a screen dot.

Title: Test method for semiconductor memory
Inventor: SAITO MASATAKA
IPC: G11C29/00
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the word line leak test requires a very long time because a semiconductor device must be left as it is for a predetermined time during a single test cycle. SOLUTION: When inputting a specified row address, an RAS signal is rendered active and a word line is driven to Vpp level. A power supply line is then disconnected from the word line 22 at the timing for rendering a CAS signal active thus floating the word line 22. Two specific bits in a column address are neglected and a Y select line 23 is decoded using the address except two specific bits. Consequently, four Y select signal lines 23 are rendered active simultaneously. This state is sustained for a predetermined time T and then delay write operation is effected before checking accurate storage of data in a memory cell 24. Since the data is written simultaneously, word line leak check test is carried out at high rate.

Filed: 1990-09-10
Abstract: PURPOSE:To prevent the occurrence of a discharge near the end of an anode by fixing an insulating film positively electrified by the DC electric field in vacuum in a fixed region from the place with the highest potential of the static electric field on the inner wall face of a vacuum container while a cathode serves as a reference. CONSTITUTION:A positive electrification film 8 with the width W1 is fixed over the surface of a neck glass 3 in the fixed region A from a graphite film 4A at the end section of a conducting film 4. The film 8 is made of an insulating thin film with the characteristic to be positively electrified when primary electrons are fed to this film in vacuum. When electrons reach the region A where the film 8 is formed, positive electrification occurs, and the potential of the region A becomes higher than the potential of the static electric field. The field intensity near the graphite end of the conducting film 4 can be sharply lowered, the field emission of electrons is suppressed, and the dielectric breakdown due to a discharge can be prevented.
