Title: Image tube device
Inventor: KINOSHITA KATSUYUKI
IPC: H01J31/50
Filed: 1989-10-20
Abstract: PURPOSE:To have observation of only a desired photo-electron image, in an image tube device having a means to convert the incident beam into electrons and an electron accelerating means to accelerate the emitted photo-electrons in the same direction as the incident direction, by bending the advancing direction of the accelerated photo- electrons, and leading the incident beam having penetrated the converting means to outside the transit region. CONSTITUTION:An incident X-ray is allowed to pass through an incident window 2a made of Be and focus on a photoelectric conversion surface 2 to be converted into electrons, and photo-electrons in an amount corresponding to the incident amount of light are released to the opposite side to the incidence. The released photo-electrons are accelerated approx. in the same direction as the X-ray incident direction by an accelerating electrode 5 and focused enlargedly by an electromagnetic convergence coil 6 on the input surface of a micro-channel plate 4 which makes electron multiplication. Thereafter the multiplied electrons are put incident onto a fluorescent surface 3 and converted into visible light. This permits the X-ray having penetrated the conversion surface 2 to run straight and collide with the inner wall surface at the bend part of a tubing 1, not reaching directly the input surface of the plate 4, and thus this X-ray does not influence the output of the fluorescent surface 3.

Filed: 1987-10-29
Abstract: PURPOSE:To prevent data which are already written from being destroyed in case of mistracking by stopping data from being written on the optical memory card when tracking error information exceeds a 2nd reference range wider than a 1st reference range. CONSTITUTION:This device is provided with a 1st comparing means 2 which decides whether or not the tracking error information is within the 1st reference range and generates a direction signal indicating the direction of correction and a 2nd comparing means 3 which decides whether or not the tracking error information is within the 2nd reference range wider than the 1st reference range. Further, when the decision result of the 2nd comparing means 3 is negative, a writing stopping means 1 stops the writing of the optical memory. Thus, when a deviation in tracking exceeds the 2nd reference range determined wider than the 1st reference range, mistracking is decided and the writing of data is stopped. Consequently, the data which are already written are prevented from being destroyed.

IPC: G11C11/401
Filed: 1994-10-14
Abstract: PURPOSE: To save power and to reduce noise by reducing the number of times of access to a row address and reducing the transients of an address terminal. CONSTITUTION: When the row addresses corresponding to two timewisely sequential inversion RAS signals match, the two inversion RAS signals are connected at a low level and unrequired row access is prevented from being executed. Also, allocation to column addresses is performed in an order from a bit whose frequency of inversion is high, the remainder is allocated to the row addresses and the frequency that the two sequential row addresses match is raised. Further, when the row access is unnecessitated, the row address is prevented from being outputted to the address terminal. Also, the bit of the column address to be accessed first is turned to be the same value as the bit of the row address supplied to the same terminal. Also, in the case of using the prescribed number of the bits among the address lines of a memory and continuously performing the access, an address value is set so as to reduce the number of times of the inversion of the respective bits.
