Patent JP-S5873233-A (JP)
Title: Semiconductor integrated circuit
Inventor: UKAI JIYUNICHI
IPC: H03K17/04
Filed: 1981-10-28
Abstract: PURPOSE:To improve the switching speed, by connecting a differentiation circuit between a gate of an MIS type semiconductor load element and an output of an MIS type semiconductor driving element. CONSTITUTION:A switching circuit consists of two MIS type semiconductor load elements T1, T2 and an MIS type semiconductor driving element T3. A differentiation circuit consisting of CR is connected between a gate G of the T2 and an output of the T3. When a signal VIN is inputted to the T3, the output becomes an inverted signal VOUT. A signal VG differentiating the signal VOUT at the CR differentiation circuit is applied to the T2. Thus, since the T2 is conductive when the signal VG exceeds a threshold value, that is, only at the switching, heat generation is suppressed to a minimum value, and the switching speed can be improved.

Abstract: PURPOSE:To reduce the uneveness of developing density accompanied with the rotation of a magnet and to improve printing quality by disposing a magnetic field detection means in the vicinity of a magnetic roller and changing a developing bias voltage in synchronism with the alternation of magnetic field detected by the magnetic field detection means. CONSTITUTION:The conveyance of developer 8 and development are performed by the magnetic roller 9 including a magnet 12 which is magnetized to be in plural magnetic poles S and N. In such a case, the magnetic field detection means 16 is disposed adjacently to the magnetic roller 9 to detect the magnetic field by the magnet 12 of a developing gap part. The alternating voltage is superposed on a developing bias impressing means 10 by an alternating voltage superposing means 17 in accordance with the change of developing checking force by the magnetic field of the developing gap part and a difference between developing force by the electric field and the developing checking force by the magnetic field is kept constant so as to reduce the variation of the force which acts to the developer 8. Thus, the unevenness of the developing density accompanied with the rotation of the magnet is reduced and the printing quality is improved.

IPC: H03H11/26
Filed: 1982-10-02
Abstract: PURPOSE:To obtain a circuit forming the time delay of an analog signal by that of a digital signal unexpensively by using a selecting circuit, an adder, a counting circuit, and a storage circuit.

Title: Address coincidence circuit
Inventor: TAKADA MASAHIKO
IPC: G06F13/14
Filed: 1988-07-12
Abstract: PURPOSE:To change a set address in accordance with the size of the address space of a CPU by using the output of an FF, which is changed at the time of detecting '1' in upper bits of the output address of a master device, as a part of the condition for address coincidence detection. CONSTITUTION:After initialization, the output of an AND circuit 7A is certainly in the low level, and the output of an AND circuit 7B is in the high level when the output of a comparator 5B is in the high level. Consequently, the output of an OR circuit 8 goes to the high level and an address coincidence signal is sent to a control circuit 9. That is, the address coincidence signal is obtained independently of address lies A17-A14. When '1' is outputted to one of address lines A17-A14, the output of the circuit 7B certainly goes to the low level because outputs Q and Q of an FF 3 go to the high level and the low level respectively, and the output of the circuit 7A goes to the high level when outputs of comparators 5A and 5B are in the high level together. Then, the address coincidence signal is sent to the circuit 9. In this case, addresses including the address A17-A14 are taken as the comparison object, and the address coincidence signal is obtained.

Filed: 1989-07-07
Abstract: PURPOSE:To enable each host system to always secure the latest file directory by storing the change information on the file directory into a work memory and transmitting the change or no-change of the file directory to other host systems. CONSTITUTION:When one of host systems 7 (71 - 7n) sets up, deletes or changes a file directory, an information recording medium 2 changes the file directory with an instruction given from the system 7.
