Title: Non-volatile semiconductor memory device
Inventor: OBATA HIROYUKI
IPC: G11C16/10
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To avoid writing error even when writing is performed with F-N tunnel mechanism using a very low level write current to assure stable program operation by setting the write voltage as the power supply voltage of a write circuit and then connecting an output of the write circuit to the bit line or Y selector via a transfer gate. SOLUTION: An address is selected in the data read period and the corresponding data is impressed to a data input line 14 to turn on the N-channel MOS transistor N05 and an output of a first inverter 12 is pulled clown to GND. Or, the N-channel MOS transistor N04 turns on and an output of the second inverter 13 is pulled down to GND to set the desired data to each latch. When the write signal PRO becomes high, a transfer gate N06 turns on to connect an output of latch and the bit line BL in order to set each bit line to the desired potential. Thereby, initialization of bit line is no longer required.

Filed: 1989-05-25
Abstract: PURPOSE:To realize the effective self-learning of play practice by storing play information for specifying play operated keys and displaying a correct play rate based upon the result of comparison between the read play information and play information generated as keys are operated. CONSTITUTION:For example, the play information specifying play operated keys is read out of, for example, a score 12 and written and set in a storage device 11. The stored play information is read out by a read circuit 14 in play order and latched and stored in a data latch circuit 16 in order. The play information generated as keys on a keyboard 17 are operated is sounded by a speaker 20 through a musical sound generating circuit 18 and also supplied to a correct keying judging circuit 21. The correct keying judging circuit 21 sends out a correct keying signal to a marking circuit 22 when judging that a key corresponding to the play information latched in the latch circuit 16 is operated. The marking circuit 22 is supplied with the number of events from a modulus counter 23 and the calculated correct operation rate is displayed on a display circuit 24 at any time. Thus, the self-learning of play practice is carried out effectively.

Title: Thermal transfer printer
Inventor: KURITA KAZUSANE
IPC: B41J2/32
Filed: 1989-05-24
Abstract: PURPOSE:To prevent the vertical shift of an ink ribbon at the time of an ink ribbon feeding by specifying a ratio of a height (h) of a hood from the top edge of a platen on the nearer side to a thermal head and a extending distance lof said hood from the surface of a platen. CONSTITUTION:A hook 9 is provided above a platen 5 so as to obtain a large delivery angle theta of printed transfer paper from the platen. In this case, the effect varies depending on a distance (h) from the top of the platen 5 to the rear of the hood 9 and an extending distance l of the hood 9 from the surface of the flat platen 5. In the case of the distance l of l<=0, a large paper delivery angle cannot be obtained even if any value is applied for the distance (h). A ratio of (h) to l, i.e. h/l, should meet the requirement of 0<h/l<=1.0 to obtain a relatively large delivery angle theta. In this construction, when transfer paper 2 presses an ink ribbon 6 on a thermal head 4, in a pressure distribution of the thermal head 4 applied to the ink ribbon 6, a vertical pressure difference in the width direction of the ink ribbon is eliminated, and the ink ribbon 6 during feeding can be prevented from being shifted upward or downward.
