Title: Method for storage of information
Inventor: JIN MIZUGUCHI
IPC: G11B7/244
Filed: 1993-03-09
Abstract: PURPOSE: To stabilize writing and reading out of information by a laser beam of the same wavelength by forming a recording layer of pigments consisting of dithioketopyrrolopyrole or dithioquinacridone and org. hydrazine on a base material. CONSTITUTION: A uniform mixture composed of the pigments selected from a group of the dithioketopyrrolopyrole, dithioquinacridone or phthalocyanine and the org. hydrazone which is a solid org. compd. is formed. The recording layer is formed by depositing this mixture by evaporation under high vacuum on a polycarbonate base material. The vapor deposition is executed in the state of crystal transformation having an absorption band in a near IR NIR region. When this base material is irradiated with the laser beam of the NIR region, the absorption of the NIR is increased by the phase transition of the absorption band and information is recorded in the form of bit. The absorption of the NIR is lessened by the phase transition after the irradiation.  The writing and reading of the information by the laser beam of the same wavelength are made possible and the storage of the information is stabilized by changing the NIR absorption of the recording layer in such a manner.

Abstract: PROBLEM TO BE SOLVED: To reduce call losses and also to suppress load on a network by generating information about the duration of a call in addition to the information about a band capacity on a network such as the reservation band capacity of a call for requesting line capacity and resources reservation and transmitting them in the network. SOLUTION: While resources reservation is performed and a band is secured between a node (a) and a node (b) in a network, the state where a resource reservation request occurs from a node (e) to a node (d) is observed this time. In this case, the node (e) already receives the duration information of a call by which a resources reservation is made between the nodes (a) and (e) from the node (a). The node (e) stores this information and information of this time, i.e. together with the duration information of the call by which a resources reservation is made between the nodes (e) and (d) in an area in a packet and transfers them to the node (d). Thus, respective nodes communicate the duration information of a call in which a resources reservation is made in a network.

Title: Memory circuit
Inventor: SUYAMA KATSUHIKO
IPC: G11C11/34
Filed: 1985-03-12
Abstract: PURPOSE:To obtain a stable required voltage by arranging so that a circuit pulling up a pair of bit lines to an electric source formed by a MES FET having the source and the gate shorted and a diode having the anode connected with the gate side between the ground and the gate of the MES FET. CONSTITUTION:The depletion type MES FET Q7, Q8 with the gate and the source short-circuited has its gate connected to the ground by diodes D1, D2. The potential of bit lines B1, B2 is limited to the forward voltage (0.6-0.7V) and is not raised above this value. A word line W goes H so that transistors Q5, Q6 are turned on. When a memory cell MC is selected, assuming that the transistor Q1 is on and transistor Q2 is off for this memory cell, the bit line B1 is lowered to ground potential through Q5, Q1 while the bit line falls to 0V by the voltage drop at the transistor Q7. Since there is no pull down by Q6, Q2 in the bit line B2, it is maintained at the non-select level of 0.6-0.7V. In such a manner, gate burning or memory data destruction may be prevented under excess bit line potential.
