Title: Television telephone terminal equipment
Inventor: INOUE SHUJI
IPC: H04N7/14
Filed: 1987-12-29
Abstract: PURPOSE:To naturally match a sight line without being conscious of a camera by a user by providing a camera at the back of a half mirror and a display device at the lower side. CONSTITUTION:A video at an opponent side projected at a display device 12 can be partially reflected to a half mirror 13 and watched. The own video partially transmits the half mirror 13 and the light is photographed by a camera 11. Thus, since the picture from here is inputted through the half mirror 13 to the camera 11 and even the picture of the opponent watches the video projected at the half mirror 13, the camera is naturally watched and the sight line can be matched with the opponent without being conscious that the video is directed toward the camera.

Title: Detector for line
Inventor: OTA MICHIHIKO
IPC: G06T7/00
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To accurately detect a line without checking an end point every time voting is performed and without increasing the division number of a parameter space. SOLUTION: A feature point coordinate (x, y) is inputted to a decision circuit 10 and the feature point coordinate is transformed to a pole coordinate (ρ, θ) by Hangh transformation. Whether or not a curve indicated by the transformed pole coordinate (ρ, θ) passes through respective candidates 1-n is judged, and in the case that the curve passes through the candidates, the feature point coordinate is inputted to a weight decision device 16, weight to be added to a vote to be voted is decided, a counter for counting the votes of the passing candidates is specified and the decided weight is inputted to the counter as the vote. Simultaneously with voting, the feature point coordinate is stored in a feature point memory corresponding to the counter to which voting is performed.  At the point of time of ending voting for the entire feature points, an arithmetic circuit 18 reads the feature point coordinate stored in the feature point memory corresponding to the counter for which the number of the votes is equal to or more than a threshold and obtains a line segment by the method of least squares or the like from the read feature point coordinate.

Title: Cmos output buffer circuit
Inventor: NISHIMAKI HIDEKATSU
IPC: G11C11/417
Filed: 1990-11-28
Abstract: PURPOSE:To reduce a power consumption at the operating time by applying the output signals of the prebuffer to the gates of the transistors on the output stage through the transistor gates and controlling the transmission gates with the input signals and output signals of the prebuffers. CONSTITUTION:The signals outputted from the prebuffers (a), (b) are transmitted to each gate of PMOS, NMOS transistors Q5, Q6 on the output stage through the transmission gates Q1-Q4, and the gates Q1-Q4 are controlled by an input I and the signals outputted from the buffers (a),(b). At the output 4, the Q6 is transferred to the ON state after the Q5 is transferred to the OFF state, when the level is changed to the L-level from H-level. Also, when the level is changed to the H-level from L-level at the output 4, the Q5, is transferred to the ON state after the Q6 is previously transferred to the OFF state. As the result, the time when the Q5, Q6 become the ON state is shortened and a feed-through current is reduced, then the power consumption at the operating time can be reduced.

Title: Disk array device
Inventor: KOIKE HIROHIKO
IPC: G06F12/00
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent the performance characteristic of a disk array device from being changed even if the disk part different in performance is subsequently added and corrected by providing a response time correction means correcting a termination report outputted to a host device in accordance with a correction value calculated by means of a correction value generation means. SOLUTION: The correction value generation means 7 compares performance for respective disk parts, which are measured in a performance measuring means 8, with a standard performance which is previously decided and generates the difference of respective performance as a correction value. The response time correction means 5 corrects the termination report outputted to the host device 1 when access is given from the host device 1 in accordance with the correction value calculated by the correction value generation means 7. The response time correction means 5 delays the termination report on the new disk part 10 of good performance to time decided by the correction value even if data transfer terminates. Thus, performance with respect to the host device is made to be leveled even if the new disk part 10 is added to the disk array device 2.
