Abstract: PURPOSE:To shorten a write time of matrix drive by providing a delay period after a reset pulse, impressing a preset pulse, providing an interval period succeeding to the preset pulse and impressing a selection voltage. CONSTITUTION:A preamble auxiliary pulse (period T3) after the delay period T2 is fixed, and a selection pulse (period T5) delayed by a certain period T4 from the pulse (T3) is succeeded.

Title: Reduced speed sensor
Inventor: SUGIMOTO TOMIJI
IPC: G01P15/00
Filed: 1986-02-27
Abstract: PURPOSE:To enable an output signal continue for a sufficiently long period by providing a backup mass which has a larger diameter than a sensing mass behind the sensing mass. CONSTITUTION:A reduced speed sensor 1 is fitted to a vehicle body so that a cap 4 is in the front in the running direction of the vehicle; and the sensing mass 9 and backup mass 10 are held by a magnet 11 at the initial position on the rear end side of a guide path 6 during a normal run. If the vehicle body is reduced greatly in speed owing to a collision, etc., an internal force in the running direction operates on the masses 9 and 10, which move forth when the reduced speed value is larger than a specific value. At this time, the gap between the masses 9 and 10 and the inner peripheral surface 3a of the guide path 6 is small, so air flowing in the gaps receives large fluid resistance and is compressed in the space in front of the mass 9 and negative in pressure in the space behind the mass 10. Consequently, the forward motion of the masses 9 and 10 is attenuated. Further, the mass 10 is larger in diameter than the mass 9, so it receives a large attenuating force and the time when the mass 9 contacts 15 and 16 is held sufficiently long, so that the output of a sensor 1 continues sufficiently.

Title: Color television signal processor
Inventor: INOUE TSUYOSHI
IPC: H04N9/78
Filed: 1989-02-20
Abstract: PURPOSE:To reduce dot interference and to suppress degradation in the horizontal resolution of a luminance signal by detecting a horizontal edge area, in which there is no correlativity between lines, and switching the outputs of a comb line filter circuit and of a notch filter. CONSTITUTION:When a composite color television signal is inputted, a comb line filter circuit 2 supplies a separated luminance signal Y to a notch filter 4 and a Y-signal switch circuit 10. The filter 4 suppresses the signal amplitude of a color carrier frequency band in order to reduce the dot interference of the Y signal and outputs the Y signal to the switch circuit 10. According to a horizontal edge signal outputted from a horizontal edge detection circuit 9, the switch circuit 10 executes control so that the horizontal edge area can select the output of the filter 4 and an area excepting for the horizontal edge area can select the Y signal from the filter circuit 2. As a result, the output of the filter 4, for which the dot interference is reduced, can be outputted to the horizontal edge area, where the dot interference is easily generated, and the Y signal, for which the horizontal resolution is not degraded, can be outputted from the filter circuit 2 to the area excepting for the horizontal edge area.

Title: Fast buffer storage device
Inventor: KAWASAKI MASAO
IPC: G06F12/12
Filed: 1989-02-21
Abstract: PURPOSE:To improve the hit rate of a cache memory efficiently by paying attention to the locality of a program on a main storage and introducing a probability method. CONSTITUTION:In general, the probability that respective divided areas R1 - RN on the cache memory are used in a next instruction step is represented as an equation I. In replace algorithm, the transition matrix of the equation I is found in each instruction execution step. Further, the transition matrix is determined by simulation where cases are assumed previously. When the same area of the arithmetic result is usable, the same area is used and when an area (i) needs be replaced, the area is replaced and the transition matrix is updated. Consequently, more accurate transition than before can be predicted to improve the hit rate of the cache, i.e. realize the more efficient cache memory.
