Title: First-in first-out control circuit
Inventor: TAGUCHI MASAYUKI
IPC: G11C7/00
Filed: 1988-12-27
Abstract: PURPOSE:To realize sophisticated function and high circuit integration effectively by providing a readout address correction control circuit, and making a readout pointer of each FIFO circuit identical to each other. CONSTITUTION:First-in first-out control circuits FIFO 1 (6-1), FIFO 2 (6-2) are used in parallel. A write data is given to data input terminals 1-1 to 1-17 in the control circuit 6-1 and a data inputted from a terminal 9 is inputted to terminals of the control circuit 6-2. The data inputted in common to the circuits 6-1, 2 is used as a dissidence detection bit of an output data. When outputs 13, 14 to the same input of the control circuits 6-1, 2 are dissident in a dissidence detection circuit 5, a dissidence detection signal 15 is outputted and given to a readout address correction control circuit 40. The circuit 40 sets the value of readout address pointers 22, 32 of the control circuits 6-1, 2 to identical values. Then the difference in the output data of the control circuits 6-1, 2 is eliminated and proper sophisticated function and high circuit integration are attained.

Title: Ink housing tank
Inventor: NAKAMURA TAKESHI
IPC: B41J2/175
Filed: 1992-12-11
Abstract: PURPOSE:To prevent occurrences of evaporation of ink and mixture of foam which causes defective printer head by housing a hollow tube having a small in an ink tank case by bending it many times over on itself, and the hollow tube store the ink continuously. CONSTITUTION:A hollow tube T having a small diameter is bent many times over on itself and housed in an ink tank case 1. The hollow tube T is charged with ink continuously. As a result, a sectional area of an end connection with a printer head to which the hollow tube is to be connected can be very small. As its sealing will be easy, evaporation of the ink and mixture of foam which causes defective printer head can be prevented. Also, as the ink is held by capillary force of the hollow tube, attaching and detaching to and from the printer head will be possible even when it is in use.

IPC: H04M3/533
Filed: 1990-11-29
Abstract: PURPOSE:To prevent a caller from being kept waiting at a most frequent traffic time by sending selectively a disconnection message or an alert message with respect to a busy state incoming notice from a network based on execution information of busy state incoming notice for each prescribed time registered in advance in a storage section of an exchange. CONSTITUTION:When a private branch of exchange 1 receives a setup message 3 being a busy state incoming call sent from an ISDN network 2 while two B channels of the ISDN are busy, a central processing unit in the private branch of exchange 1 references the handling of an incoming call corresponding to the time at the arrival of a call of a busy state incoming call processing table. Then an enable or disable incoming call is discriminated in response to the call handling and either an alert message 4 or a disconnection message 5 is immediately sent to the ISDN network 2. The handling of the busy state incoming call is set to be allowed except for a most frequent time zone. Thus, only the busy state incoming call at the most frequent time zone is rejected and the caller is not kept waiting.
