Title: Information recording medium
Inventor: TAKEHARA HIDEAKI
IPC: G11B7/243
Filed: 1985-02-13
Abstract: PURPOSE:To enable erasing of recorded information signals with a special erasing operation but not with an ordinary erasing operation by constituting an information layer to consist of a first phase of erasing, a second phase of reversible recording and a third phase of retention of recording. CONSTITUTION:A recording layer of an information recording medium is consisting of the following three phases; (a) a first phase which is realized by applying energy to the layer constituting material and subsequently by slowly cooling to a room temperature to be brought to a condition A. (b) a second phase in which a condition B is realized by energy application and heating, then a quick cooling. (c) a third phase in which a condition C is realized by application to the recording layer of energy larger than the ones applied when the first and the second phases were obtained, and then afterwards, by rapidly cooling the layer. The information signals on the third phase will not be erased due to the existence of the first phase, but erasing of already recorded information is carried out by giving energy which would pass through an energy barrier Ec, and by cooling slowly.

Title: Semiconductor integrated circuit device
Inventor: TAKUWA MIKIO
IPC: H03K19/177
Filed: 1988-02-04
Abstract: PURPOSE:To reduce the number of elements required to constitute a delay circuit by a method wherein a power supply voltage which is lower than that of a logic circuit part is applied to the delay circuit part and the delay time of a signal in individual logic gates is delayed. CONSTITUTION:Because a delay circuit part 2 is driven by a power supply voltage Vcc' (e.g., 2.5V) which is lower than a power supply voltage Vcc (e.g., 5V) of logic circuit parts 1, 4, the delay time of a signal to be input from the logic circuit part 1 to the logic circuit part 4 through individual inverters 2a of five stages is also longer than the delay time of a signal in the logic circuit parts 1, 4. Accordingly, the same delay time can be realized by the small number of inverters 2a as compared with a case driven by the power supply voltage Vcc; the number of FETs required to obtain the desired delay time can be made small; more FETs can be used in the logic circuit parts 1, 4 and the like.
