Filed: 1994-06-13
Abstract: PURPOSE:To avoid or lighten hot heat in summer season or the like for obtaining a comfortable riding environment by crowning a turned down dish-shaped cover body over the roof of a passenger car body with a space kept between them, and forming a ventilating opening part whose opening reduces or expands gradually before and behind in the travel direction of the passenger car using the above space. CONSTITUTION:A carrier 10 having a passenger car body 20 suspended on a rope grasping machine to grasp a rope through a suspension machine 12 is moved by the circulating movement of the rope, and a turned down dish-shaped cover body 30 is crowned over the roof 22 of the passenger car body 20. The cover body 30 is composed by sewing together two main plate member 31, 31 and a longitudinally curved member 32 through a connecting part 33, and a rectangular opening part 35 is provided near the center of the cover body. A gap 43 for circulating air is therefore formed by the cover body 30 between it and the roof 22.

Title: Fault monitoring counter control system
Inventor: SUGA KAZUKO
IPC: G06F11/30
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent such a case where a monitoring object device started in its operation after the recovery from a fault is wrong recognized as a fixed fault to be separated from a fault monitoring counter control system by clearing only a fault monitoring counter when a hot line connection/disconnection processing of the monitoring object device is over. SOLUTION: A hot line connection/disconnection end notification reception part 27 of a diagnostic controller 20 detects the hot line connection/disconnection end notification received from a hot line connection/disconnection end notification sending part 12 after the hot line connection/disconnection processing of an information processor 10, i.e., a monitoring object device. Then the drive notification is sent to a monitoring counter clearing processing part 26 together with the corresponding device number of the processor 10, and the count value of the processor 10 is cleared.  As a result, the monitoring object device where the recovered hot line connection/ disconnection processing is over is never recognized as a fixed fault unless a fault monitoring counter 23 is continuously counted up to its upper limit value before the next time limit of a monitoring timer 24 since the relevant area of the counter 23 includes no remaining count value. Thus, the relief factor to the fault of the monitoring object device is increased.

Title: Waveguide-microstrip line converter
Inventor: WATANABE HIROSHI
IPC: H01P5/107
Filed: 1981-09-29
Abstract: PURPOSE:To attain excellent coupling with both vertical and horizontal polarized waves, by providing a strip line antenna and a resonance window in a waveguide. CONSTITUTION:A polarized wave in parallel with a short axis of a resonance window can tramsmit a resonance window, but a polarized wave in parallel with a long axis cannot trasmit, and is reflected, because the resonance window shows a large reactance. The V wave is reflected at the 1st resonance window and absorbed by an antenna provided to a microstrip base 15. The H wave is  orthogonal to the antenna provided to the base 15 and has the polarized wave in the direction of the short axis of the 1st resonance window, then the wave transmits the 1st resonance window. After the H wave is absorbed by the antenna  provided to the 2nd microstrip base 16, the wave is also reflected at the 2nd  resonance window and absorbed by the antenna.

Title: Josephson logic circuit
Inventor: SUZUKI HIDEO
IPC: H01L39/16
Filed: 1990-06-13
Abstract: PURPOSE:To improve the fanout capability by increasing the output logic level of a 2nd Josephson circuit 31 including a Josephson junction made of a ceramics group superconducting material with the gap energy of the ceramic group material. CONSTITUTION:The logic level of a 2nd Josephson circuit 40 is larger than the output logic level of a 1st Josephson circuit 40 almost by one digit. This is because the circuit 30 includes a metallic group Josephson junction, while the circuit 40 includes a ceramic group Josephson junction. Thus, plural input side magnetic field coupling lines 53 connected serially are driven by the output of the 2nd Josephson circuit 40 without any hindrance and the fanout capability is improved without incurring the prolonging in the switching time.

Filed: 1988-06-24
Abstract: PURPOSE:To easily select a device provided or not provided with an optional function corresponding to a request of customers by a method wherein an optional circuit and an optional function selecting pad connected to a part of the optional circuit are previously formed in a semiconductor chip. CONSTITUTION:When an optional function selecting pad 2 is not connected with a VEE lead 3 through a bonding wire 4 in a wire bonding process, or when the optional function selecting pad 2 is in a free state, a power supply circuit 1 serves in such a manner that a potential of a point P becomes higher than VEE by a forward voltage of diodes D3 and D4. That is, at this point, the potential of the point P becomes equal to the saturation voltage of a transistor Tr. In result, the transistor Tr is turned ON. On the other hand, when the optional function selecting pad 2 is connected with the VEE lead 3 through the bonding wire 4, the potential of the point P becomes equal to VEE, and as the VEE is lower than the saturation voltage of the transistor Tr, the transistor Tr is made to be turned OFF.
