Title: Memory device
Inventor: TAIRA KENICHI
IPC: H01L27/10
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a memory device capable of operating on a low voltage and holding multi-valued information. SOLUTION: A first barrier layer 21, a quantum dot 22b, a second barrier layer 23, a quantum dot 24b, and a third barrier layer 25 are successively laminated adjacent to a conduction layer 13. The quantum level of the quantum dot 22b is higher than that of the quantum dot 24b. Distances between the quantum dots 22b and 24b and the conduction layer 13 are set to enable electrons to tunnel through. A voltage is applied in pulses to a gate electrode 15. Voltage pulses are selectively determined on width and height, whereby electrons are selectively stored in the quantum dots 22b and 24b to vary a threshold voltage. Multi-valued information are held, making the difference between the quantum dots 22b and 24b, where electrons are accumulated serve as a data difference.  Since the electrons are transited through resonant tunneling, a memory device having this constitution is capable of operating on a low voltage.

Title: Hanging gate
Inventor: FUMIMOTO EI
IPC: E06B11/00
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent buckling of braces. SOLUTION: A connecting shaft 20 connecting braces 7, 7 together is provided with a pulley 21 at the reference engaging part 8 of a travel rod 4 with the brace 7, and a peripheral groove 24 is engaged with a flange 15 to enable the reference engaging part 8 to move along the travel rod 4. Bolts 26 are provided above and below the reference engaging part 8 in such a way as to be freely inserted and removed, to limit the range of movement of the pulley 21. Even if the travel rod 4 moves up and down as a hanging part is adjusted, the reference engaging part 8 moves relative to the travel rod 4, preventing buckling of the brace 7. Also, since the range of movement of the pulley 21 is limited, the oscillation of the brace 7 does not become unstable.

IPC: H04M7/00
Filed: 1990-08-09
Abstract: PURPOSE:To avoid waste by allowing a center exchange to access an external information source periodically and allowing plural floor exchanges to acquire information from the center exchange without direct access to the external information source. CONSTITUTION:An external dialing section 21 accesses an external information source IS able to be connected through a trunk line 19 at a prescribed time interval via a center exchange 12. Moreover, an external reception section 22 receives the information sent from the external information source IS with the access from the external dialing section 21 via the center exchange 12. Then an internal transmission reception section 23 stores the information transferred from the external reception section 22 via the center exchange 12, replies a special number sent from a subscriber 13 to a line wire 16 and applies information to the subscriber. Thus, the service offered by the external dialing section 21, the external reception section 22 and the internal transmission reception section 23 is received by a subscriber 13 of each floor exchange 11 under the same condition in common. Thus, the system is economical more than that in the case of accessing a public network.

IPC: B41J33/16
Filed: 1991-08-21
Abstract: PURPOSE:To provide a reel enabling bidirectional printing in a printer using an ink ribbon. CONSTITUTION:When the reel serves as a drive reel, at first, the driving force of a motor is transmitted to a gear 16. Since the gear 16 is brought into contact with a base 15 under pressure by the spring force of a spring 22, the driving force transmitted to the gear 16 is transmitted to felt 17, the base 15 and a reel cap 14 in this order to take up an ink ribbon. When the reel serves as a follower reel, friction force is generated between a spring arranging stand 21 and a fixing member 19 by the spring force of a spring 23 because the fixing member 19 is fixed to a carriage when the reel cap 14 is ready to rotate to apply back tension.

CONSTITUTION: The time recorder with days of the week is provided with a means for tabulating days of the week in the firstdays of specific years and intercalary years, a means for tabulating relative changes of days of the week in the first days of respective months and a means for determining days of the week by using relative changes of days of the week in the first days of specific years and days of the week in intercalary years and the first days of respective months from a date starting calculation.  Namely a table obtained by numerizing days of the week in the first days of twenty years by values of one digit, giving '1' to the 2nd digit of a value expressing an intercalary year and giving '0' to the 2nd digit of a value expressing a normal year to discriminate the intercalary year and a table expressing days of the week in the first days of respective months of an year by values of one digit as relative differences of days from the first day of the year are stored in a read-only memory 50. Since days of the week in dates after the date starting the calculation can be calculated only by inputting the calculation starting date, storage capacity and a processing means can be suppressed to the minimum.

In the groove 5, the winding-part conductor 2 is buried and an insulating layer 4 is buried on the conductor 2. The surface of the insulating layer 4 substantially agrees with the surface of the substrate 1. Therefore, a step part is not yielded on the taking-out conductor 3, which is formed on the layer 4, and wire breakdown and the increase in resistance are avoided. When the groove 5 is made shallow and the insulating layer 4 is made thick, the stray capacitance between the winding-part conductor 2 and the taking-out part conductor can be reduced with flatness being maintained.
