IPC: H04N9/07
Filed: 1981-05-06
Abstract: PURPOSE:To provid an image pickup device with a negative-positive inverting function by providing a changeover switch for inverting the phase of an alternating signal supplied between electrodes. CONSTITUTION:Index electrodes provided on the photoelectric conversion surface of a ''Trinicon '' camera 1' are supplied with an alternating signal, which synchronizes with a scanning period, from a 1/2 counter 24. By this alternating signal, a composite signal of color sequence signals changing in phase alternately appears at the input side of a preamplifier 2. On this composite signal, an index signal is superposed and the phase of the index signal is inverted by 180 deg. to perform synchronous detection, so that the phase of a color signal is inverted by 180 deg.. The phase inversion of the index signal is performed by changing the phases of an fH/2 alternating signal applied to the index electrodes by providing a changeover switch 18 to the primary coil side of a transformer T.

IPC: H04N5/232
Filed: 1995-03-27
Abstract: PURPOSE: To detect a focus with high precision regardless of a play of a lens drive mechanism. CONSTITUTION: A level of a high frequency component of an image signal picked up by an image pickup means 2 through a lens 1 is extracted by an AF evaluation detection means 3 and a control means 4 controls a lens drive means 5 to reciprocatingly move the lens 1 by a prescribed moving amount each so as to maximize the level as the AF evaluation value and the lens 1 is subjected to mount-climb control up to the focal point. When an inversion detection means 6 detects inversion of the lens 1, a revision means 7 adds an additional moving value to the prescribed moving amount. Furthermore, a focal distance detection means 8 detects a focal distance of the lens 1 and an inhibit means 9 inhibits revision of the moving amount when the focus is not biased toward the wide range end.

Title: Sports shoes
Inventor: BARUKUHOFU KURAUSU
IPC: A43B5/04
Filed: 1985-03-30
Abstract: A saddle-shaped retention member is arranged within a ski boot and can be brought into contact with the middle region of the foot or with a portion of a padded inner shoe covering this middle foot region. Two cable strands engage this retention member, each of which extends on one side of a shell member of the ski boot. Each of these cable strands extends through a bore penetrating a pivot pin. A rear upper portion of the ski boot is pivotably fastened to the shell member by this pivot pin. These penetrating bores are arranged above the pivot axis of the rear upper portion in spaced relationship thereto. The cable strands are fastened to a tensioning lever which is pivotably mounted on the rear upper portion. Since the cable strands extend above the pivot axis of the rear upper portion, the retention member can move forwardly away from the heel region of the ski boot when the upper portion of the ski boot moves forward and entrains the rear upper portion with it toward the toe of the ski boot. This forward motion of the retention member creates space for the middle foot region, which lifts during such a forward motion.
