Title: Ophthalmologic photographing device
Inventor: OGAWA TETSUJI
IPC: A61F9/007
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To allow a diagnostician to quantitatively transfer an image judged as adequate for a diagnosis to a photographer even when the photographer and the diagnostician differ. SOLUTION: When a photographing switch 19 is pressed after this device is positioned, the signal is detected by a photographing operation controller 16, and a photographic light source 4 emits light via predetermined luminescence energy. The fundus image of an eye to be checked is formed on an image pickup means 11. The obtained image signal is converted into a digital signal by an A/D converting means 13 and is recorded in an image memory 14. A luminance information detection section 15 generates a histogram from the image information of the image memory 14. A reference value input section 21 receives and stores the setting of the reference value that the frequency of the minimum luminance section of the histogram is a prescribed value or below or the frequency of the maximum luminance section is a prescribed value or below.  A comparison section 20 compares the histogram with the reference value and instructs a warning generation section to issue a warning if the histogram does not satisfy the reference value.

Title: Nonvolatile semiconductor memory
Inventor: KIRISAWA RYOHEI
IPC: G11C17/00
Filed: 1989-02-22
Abstract: PURPOSE:To attain electric write with high reliability by keeping a source, a drain and a base to a low level at erasure and write and applying a reverse high voltage to a control gate at the erasure and write. CONSTITUTION:Data in memory cells M1-M8 are erased by applying a negative high voltage to all word lines WL and connecting all other terminals to ground, electrons are emitted to the base board from a floating gate in all the memory cells to decrease the threshold level. The data write ('0' write) is implemented to a memory cell whose threshold level is decreased by applying electron injection to the floating gate selectively from the remote bit line BL to move the threshold level to a positive polarity. Since the data write and erasure is implemented by giving a positive and negative high voltage to the word line, the base current is less, the deterioration in this gate insulation films 3, 5 is suppressed and the reliability of a nonvolatile memory is improved.
