Title: Semiconductor device
Inventor: TANAKA YASUNORI
IPC: H03K19/00
Filed: 1985-09-30
Abstract: PURPOSE:To attain miniaturization in the chip size and cost-down by using a clock signal to as to bring a CMOS logical gate into the operating or non- operating state thereby decreasing number of transistors (TRs) constituting a clocked logical gate. CONSTITUTION:Power supply terminals of the CMOS logical gates G1-Gn controlled by the same clock signal phi among clocked logical gates are connected in common and a PMOSFET PO and an NMOSFET NO inserted between the common connected point and power supplies VDD, VSS respectively. When an inverted clock signal; the inverse of phi is at an H level, the PMOSFET PO is conducted because its gate reaches an L level and the NMOSFET NO is conductive because the gate reaches an H level. Thus, the power supplies VDD, VSS are fed to the CMOS logical gates G1-Gn, which are activated. When the inverted clock signal; the inverse of phi goes to an L level, the PMOSFET PO is cut off because its gate reaches an H level and the NMOSFET NO is cut off because its gate reaches an L level. Thus, the power supplies VDD, Vintegral S are not fed to the CMOS logical gates G1-Gn, which are inactivated.

Title: Horizontally pulling type breakwater facility
Inventor: SHINODA KUNIHIRO
IPC: E02B7/20
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a horizontally pulling type breakwater facility capable of being applied even at a place (a gate and a movable type breakwater) having severe operating conditions. SOLUTION: A water channel 3 is totally opened by entering a door body 7 into a housing dock 4 at the normal time. When the water channel 3 is interrupted, the door body 7 in the housing dock 4 is discharged (horizontally pulling and movement) towards an opposite bank 2, and the door body 7 is shifted in the direction of the interruption of the water channel. The front end of the door body 7 is inserted into the gate groove 5 of the opposite bank 2, and the horizontal movement of the door body 7 is stopped and the water channel 3 is totally closed. The door body 7 receives pressure such as wave pressure, but a section forming the gate groove 5 and the section of the entrance of the housing dock 4 resist the pressure as pressure fulcra to both ends of the door body 7 after the total closing.  Accordingly, operating conditions are not constrained and the water channel 3 is interrupted quickly, thus allowing easy application even at a place having severe operating conditions.

Title: Optical fiber observing method
Inventor: SATOU MAKOTO
IPC: G02B6/24
Filed: 1983-11-18
Abstract: PURPOSE:To observe clearly the state of an optical waveguide part of an optical fiber by using a plane light source as a light source of transmitted light illumination. CONSTITUTION:Rays 5 are projected from a plane light source 2 to an optical fiber 1 to observe the optical fiber 1 from the direction of an arrow 3. The state of an optical waveguide part 4 is observed with the light passing this part, especially, the peripheral part because a steep gradient of refractive index distrubution exists in this peripheral part. When the plane light source is used, rays pass the peripheral part of the optical waveguide part, and much rays which do not meet conditions of observation possibility exist. Only a part of parallel rays satisfies conditions, and consequently, the observed area in the optical fiber is limited.

Filed: 1990-08-21
Abstract: PURPOSE:To make a telephone communication terminal possible to carry out sending and receiving data with the user's visual aid by displaying data on the display section of the main body of the telephone communication terminal during the communication. CONSTITUTION:When no data is input in a telephone communication terminal, data input keys on the operating section 4 of a telephone communication terminal are pushed to input data represented with predetermined characters to a memory 5 in advance. Sending data is carried out when data is in store in the memory 5 in advance. A control section 6 sends out a control signal L to switch a communication section 2 to data communication, and also sends out sending data to a display section 3. When carrying out data communication, the communication section 2 is switched to data communication. Since the control section 6 sends out data received to both the display section 3 and memory section 5, the data received is stored in the memory section 5 and also displayed on the display section 3. With this, the performance and application of the telephone communication terminal can be enhanced.

Further, the current values of the current sensor of a right-hand side normal connection box 41 is also almost I/3. Further, the accident current I' which flows to the right from the accident point 60 is shunt by the ground line 40 in a 1st normal connection box 43 to almost I'/3 and measured by respective current sensors 56. Consequently, it is discriminated that the accident point is on the side of the bond wire of a current sensor which detects the large accident current.
