Title: Drain facility of nuclear reactor power plant
Inventor: SASAMURO TAKEMI
IPC: G21D1/00
Filed: 1989-11-17
Abstract: PURPOSE:To eliminate a thermal shock by providing a by-pass circuit which by-passes the check valve on the exit side of a drain pump, supplying condensed water from a drain injection point at the start of operation, and circulating it in the opposite direction from that of normal operation. CONSTITUTION:At the start of operation, a drain tank water level control valve 16 is slightly open and condensed water begins to flow back and is limited by a flow rate limiting device 21 to a necessary loose flow rate to flow in a drain pump 12, so that loose flow rate operation is started. Further, this condensed water passes through an entrance valve 13 and a by-pass drain valve 17 and is collected in a by-pass drain system 18. When a 1st pump 12 is started, the valve 16 is controlled automatically to an opening extent corresponding to the water level in the drain tank and the valve 17 is closed. In this state, fluid discharged from the actuated pumps 12 flows back to remaining drain pumps and is warmed up to circulate. Therefore, the temperature difference when the pumps 12 are actuated is up to about 40 deg.C and there is not the problem of a thermal shock.

Title: Ultrasonic diagnostic apparatus
Inventor: ANDO MOTOYOSHI
IPC: A61B8/00
Filed: 1987-11-27
Abstract: PURPOSE:To enhance operability, by mounting the undefined switch provided to an ultrasonic probe and a means for allotting the arbitrary switch on the keyboard of an ultrasonic diagnostic apparatus main body to the undefined switch to perform definition and substituting the switch to which the undefined switch is allotted. CONSTITUTION:When a definition is given by respectively allotting switches 6a, 6b to an undefined switch 8a, 8b by the operation of a definition switch 7, the operating signal of the undefined switch 8a starts the same control as that at the time of the operation of the switch 6b and the operating signal of the undefined switch 8b starts the same control as that at the time of the operation of the switch 6b. That is, an ultrasonic diagnostic apparatus performs B-mode operation on the basis of the former and performs M-mode operation on the basis of the latter. Therefore, when two undefined switches 8a, 8b are defined preliminarily, an operator pushes the undefined switch 8a or 8b while operating an ultrasonic probe 3 to make it possible to observe a B-mode or M-mode image on a CRT 4.

Filed: 1986-12-16
Abstract: PURPOSE:To improve the efficiency of a multiple output by supplying a microwave of an opposite phase to both ends of a microstrip line from a microwave monolithic oscillator using an astable multivibrator and extracting an output from a point selected on the strip line. CONSTITUTION:Outputs 0, pi difference phase by 180 deg. from the microwave monolithic oscillator 1 is fed to feeding terminals 3, 3' at both ends of the microstrip line 2. Each effective length between an output terminal 4 and the terminals 3, 3' on the strip line is equal and an integral number of multiple of the wavelength of a fundamental wave of the microwave from the oscillator, the microwaves of the phases 0 and pi are canceled together at the terminal 4, the harmonic components of the oscillator having frequencies being an even number of multiple of the fundamental wave give the same phase and the harmonic components at the even number order are outputted from the terminal 4. In this case, the terminal 4 is short-circuited equivalently at the fundamental frequency, the impedance is 0 and the microwave from the oscillator is reflected toward the oscillator at this point thereby increasing the nonlinearity of the oscillator and decreasing the loss at the multiple waves. Moreover, in selecting said effective length, the output of a required frequency is obtained.

IPC: H01S5/00
Filed: 1987-11-25
Abstract: PURPOSE:To obtain a high output laser ray in a fundamental mode from a wide active region by a method wherein an active region is made to be multistage, the width of a part of the active region is controlled to be certain value adaptable only to a fundamental mode, and the whole active region is structured so as to oscillate in a fundamental mode. CONSTITUTION:An active region 7 is composed of an AlGaAs active layer 9 provided with a wide active region, a second active layer 10 whose active region is controlled to be a certain value in width W' adaptable only to a fundamental mode, and an intermediate clad layer 11 of AlGaAs which has such a composition ratio of Al and a thickness that the above two active regions can be made to combine optically with each other. Two active regions are optically combined, wherefore a higher order mode that is zero in an electrical intensity at a horizontal center of the first active region is hardly excited due to the gain concerned when the first active region is optically combined with the second active region which is allowed only to oscillate in a fundamental mode that has an electrical intensity peak at a horizontal center of the second active region even if the first order mode is adaptable to the first active region because of its large width W, so that the active regions oscillate only in a fundamental mode.

Abstract: PURPOSE:To execute a high-speed switching action with a small-sized and, simultaneously, easy constitution by supplying a current through a first FET to the collector of a first output transistor when the first output transistor is in a low level condition, and clamping between the collector and base of the output transistor in a prescribed potential. CONSTITUTION:When an input signal is changed to the low level condition, the output terminal of an inverter circuit I3 is changed from the low level condition to a high level condition, and an output transistor Q6 and an MOS type FET (NMOS) N5 of N-channels are changed from a non-conductive condition to a conductive condition. NMOSs N3 and N4 are changed from the conductive condition to the non-conductive condition, the base charge of an output transistor Q7 is extracted by an NMOS N5, and the output transistor Q7 is made into the non-conductive condition. At such a time, since the output transistor Q7 is not made into a deep oversaturated condition, the output transistor Q7 can be changed from the conductive condition to the non-conductive condition at a high speed. Consequently, the switching action can be executed at a high speed.
