Title: Differential amplifier circuit
Inventor: KONDO KENJI
IPC: H03F3/345
Filed: 1987-09-02
Abstract: PURPOSE:To constitute a circuit with less signal delay by using PMOS transistor(TR) and NMOS TR as equi-potential TRs so as to form CMOS and turning on each TR simultaneously to make equi-potential configuration. CONSTITUTION:The PMOSTR P3, NMOSTR N4 are used as equi-potential MOS TRs to form a CMOS and control signals VA, VA' of inverted phase are given simultaneously to gates of each MOS TR. Complementary data VIN1, VIN2 from memory cells 1, 2 are given sequentially in opposite phase to gates of the MOS TRs N2, N3 of a differential pair via a line 4. When a selection signal VC goes to a high level and a differential amplification state is attained, in the absence of process fluctuation, the common potential after equi-potential processing is an intermediate potential between the signals VIN1, VIN2 and gate- source voltages VGSP, VGSN of the MOS TRs P3, N4 are made equal and the current capability is made identical. Thus, outputs VOUT1, VOUT2 are outputted without delay in following to the inversion of the input signals VIN1, VIN2.

Title: Control system
Inventor: MATSUBARA YUUSAKU
IPC: G05B19/05
Filed: 1982-12-15
Abstract: PURPOSE:To simplify constitution and to decrease the number of connection lines by delaying and supplying a switch selection signal for selecting data from a signal source to a switch means through a processor. CONSTITUTION:The processor 1 supplies a control signal to a decoder 16 and an address setting circuit 17 through a bus 15. When the address in the control signal coincides with the address set in the address setting circuit 17, the circuit 17 outputs an H-level signal to activate the decoder 16. The decoder 16 drives the driving circuit 19 corresponding to the address to change the switching mode of a latching relay 20. In this case, the processor 1 outputs a control signal having duration necessary for the operation of the relay 20. A switch selection signal 21 from the decoder 16 is delayed 22 and supplied to a switch selecting circuit 24, which selects data from the signal source 23 and sends it to the processor 1 through the bus 15. In this case, the signal is made to have duration shorter than the time necessary for the operation of the relay 20 so that the relay 20 does not operate.

Filed: 1982-12-16
Abstract: PURPOSE:To prevent a defective contact on the mounting of a pellet positively by sufficiently taking the thickness of glass attached to a mesa groove on the lower side in order to effectively obviate a glass swelling resulting from field concentration in a mesa shoulder section, and to form structure capable of sufficiently resisting stress by attaching glass so that the mesa shoulder section of the mesa groove on the lower side is coated with an oxide film at the step of the electrodeposition of glass. CONSTITUTION:Mesa grooves 2, 3 are formed to the surface and back of the pellet 1. Both surfaces of the pellet 1 are oxidized uniformly. Consequently, oxide films are formed in the whole region of the exposed surfaces of the mesa grooves 2, 3. The oxide films in the mesa grooves 2, 3 are removed selectively. The oxide films in the grooves are removed while the mesa shoulder sections of the mesa grooves 3 on the lower side are left as they are coated with the oxide film 4. Glass is electrodeposited on the mesa grooves 2, 3 at the step when processes mentioned above are completed. Field concentration in the mesa shoulder sections 3a of the mesa grooves 3 on the lower side is relaxed more than the mesa shoulder sections 3a are not coated with the oxide film on the electrodeposition of glass because the mesa shoulder sections 3a are coated with the oxide films 4.

IPC: H01L39/22
Filed: 1988-09-05
Abstract: PURPOSE:To obtain a high-performance Josephson device by a simple process by establishing a junction layer made of a metal oxide which has a different structure from that of a metal oxide superconductor between a pair of electrodes made of a metal oxide superconductor. CONSTITUTION:Metal oxide superconductive thin films 13 and 14 are formed on the surface 12 of a substrate 11 by, for example, the sputtering method. Also, a junction layer 15 is formed between the superconductive thin films 13 and 14. The layer 15 is formed by irradiating an inative gas ion such as argon on the surface of the metal oxide superconductive thin film 13. By irradiation of the inative gas ion, the crystal structure of the metal oxide superconductive thin film is destroyed in a very shallow area near the surface and superconductive properties are taken away. Therefore, a tunnel-type or weak-connected type Josephson junction is realized which is structured by the superconductive thin films 13 and 14 and the junction layer 15 which is formed between the superconductive thin films 13 and 14 and which has no superconductive properties.
