Title: Status value sampling circuit
Inventor: ISHIKAWA TOSHIO
IPC: G06F11/30
Filed: 1989-05-18
Abstract: PURPOSE:To completely sample status values at the time of detecting a fault by updating and storing the contents of plural flip flops or registers in plural reading registers synchronously with a clock signal and reading out the stored contents at the time of detecting the fault. CONSTITUTION:During the normal operation of an information processing system, the status values of many flip flops 1 or registers 2 are stored in their corresponding registers 3-1 to 3-i synchronously with a clock signal. When the information processing system detects a fault, an error flip flop 6 set up by an error signal outputs a holding signal to the reading registers 3-1 to 3-i and the status values of the flip flops 1 or registers 2 stored in the registers 3-1 to 3-i are held at that time. When a shift mode signal 300 is set up to sample the status values, the registers 3-1 to 3-i execute shift operation and the status values of many flip flops 1 or registers 2 are outputted by a shift clock signal. Thus, the status values can be completely sampled at the time of generating the fault.

Filed: 1990-05-15
Abstract: PURPOSE:To prevent the formation of an unnecessary black image on a developer sheet by exposing the limited area (an unexposure part) of a photosensitive recording medium by the use of an auxiliary exposure device. CONSTITUTION:When a lamp 42 exposes the photosensitive recording medium 50 for scanning exposure, a sensor bar 35 prevents the trail end of the exposure area X of the photosensitive recording medium 50 from being exposure, so that the trail end becomes an unexposed part. However, the trail end has been already exposed by the auxiliary exposure device 92. That is, the trail end Ya of the unexposure part Y has been already exposed by the auxiliary exposure device 20 disposed in the vicinity of the unexposure part Y situated sequential feeding one previous to exposure part X. At this time, an auxiliary exposure lamp 93 exposes the trail end Ya of the unexposure part Y; however, since the enclosure main body seals tightly the side where trail end Ya is situated, the light of the auxiliary exposure lamp 93 does not leak from the enclosure main body.

Title: Method and device for analyzing japanese morpheme
Inventor: KAMEDA MASAYUKI
IPC: G06F17/22
Filed: 1992-04-20
Abstract: PURPOSE:To make it possible to analyze a morpheme without using a dictionary of a large size by segmenting a morpheme character string from a 'KANAJI' (Chinese character)/'KANA' (Japanese syllabary)-mixed Japanese sentence based upon a morpheme dictionary, allocating a morpheme speech part candidate to the morpheme character string and inspecting parts of speech of adjacent morphemes based upon an adjacent morpheme speech part connection table. CONSTITUTION:Objective character strings S are extracted, the morpheme of the longest coinident character string segmented based upon an extended dictionary and the speech part candidates of the morpheme are set up (steps 1, 2). When the segmentation is failed, whether the leading character string of the sentences S is 'HIRAGANA's (cursive 'KANA' characters) or non 'HIRAGANA's is judged. When the character stirng is 'HIRAGANA's, the morpheme of the longest coincident 'HIRAGANA' character string is segmented based upon a 'HIRAGANA' adjacent dictionary and a 'HIRAGANA' independent word dictionary and the speech part candidates of the morpheme is set up (step 5). In the case of the non-'HIRAGANA' character string, the segmentation of the same character sort character string is executed and the morpheme speech part candidate of each character sort is set up (steps 6, 7). The speech part candidate is deleted based upon the inspection of connection with the morpheme speech part candidate of the preceding morpheme (step 8).
