IPC: G11C11/34
Filed: 1987-08-05
Abstract: PURPOSE:To stabilize a data bus for readout without generating the deviation of timing by adding a few number of elements, by connecting the data bus for readout to potential stabilized by a transmission gate which sets the inversion signal of a readout signal as a control signal. CONSTITUTION:When readout is performed on a RAM circuit, the readout signal R goes to a level 'H', and a transmission gate 14 is closed, and the content of a selected RAM cell 1 is read out. When the readout signal R goes to a level 'L', the transmission gate 14 is opened, and the data bus RBUS for readout goes to a power source level 'H', and the inverse of RBUS goes to the level 'L', then, a sense amplifier 16 is stabilized. Thus, it is possible to stabilize the data bus for readout by adding the number of elements fewer than that in a conventional technique, and furthermore, to obtain an effect making consideration for a timing problem unnecessary.

IPC: A63B37/12
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To improve distance performance, a hitting feeling and spin performance by setting the ratio of compression values of a golf ball to the core, and the cover hardness to specified values, respectively. SOLUTION: The ratio of the compression value of a golf ball and to a compression value of the core is set to 1.2 or more and less than 1.5. If the ratio is less than the above value, repulsiveness becomes low, and if above, the ball is too hard so that a feeling of hitting a ball is deteriorated. Further, the hardness of the cover is set to Shore hardness of 62 or less. If it exceeds the value, spin performance is deteriorated. The cover is formed by a composition in which 10-50 parts by weight of diene rubber is dispersed in 50-90 parts by weight of ionomer resin with a particle diameter of 5 μm or less. Thus, hitting feeling, repulsiveness and spin performance can be improved.
