Title: Cooling system for natural heat radiation type containment
Inventor: TAKAHASHI HIDEAKI
IPC: G21C15/18
Filed: 1989-03-28
Abstract: PURPOSE:To cool a nuclear reactor containment for a long time by leading condensed steam from a dry well to a steam injector installed on the outside of the nuclear reactor containment and transmitting the heat to water flowing from a heat exchanger to the steam injector to condense the steam. CONSTITUTION:Water whose temperature is raised by the energy of condensed steam is discharged at an exit pipe 11c of a steam injector 8. The temperature of water is raised until a stable discharge pressure is obtained after the start of the operation of the steam injector 8, and the water flows into a suppression pool 4 by a by-pass pipe 11e, and water whose temperature is raised is flowed to a heat exchanger 9 again through a return pipe 11d after the discharge pressure is stabilized. The water flowing to the heat exchanger 9 transmits the heat to sea water in a cooling pool 10 and is cooled. Since the quantity of water in the pipe connecting the steam injector 8 and the heat exchanger 9 is increased according as condensation advances, water is flowed to the suppression pool 4 by an overflow pipe 11f connecting the heat exchanger 9 and the suppression pool 4. The operation is repeated to always stably remove the heat regardless of the reduction of the pressure of steam.

Abstract: PURPOSE:To prevent printing disturbance due to dust and other causes by providing an integral assembly of an ink cartridge and an ink mist absorber and replacing the ink mist absorber at the same time as the ink cartridge is replaced. CONSTITUTION:A carriage cover 10 and an ink mist absorber 11 are constituted in an integral assembly, and a claw 17 provided on an ink cartridge 16 is fitted to a window 13 installed on the carriage cover 10.

Abstract: PURPOSE: To arbitrarily select heat utilizing system pressure from atmospheric pressure to atomic reactor side pressure under the condition that the atomic reactor side pressure is higher than several ten order barometric pressure by communicating molten salt as a refrigerant through a cooling loop via two heat exchangers with a high temperature gas furnace and a low pressure heat utilizing system.  
     CONSTITUTION: An atomic reactor heat exchanger consists of a primary cooling loop 2 for flowing primary coolant (helium) of a high temperature gas furnace core 1, an intermediate heat exchanger 3, a secondary cooling loop 5 for flowing secondary coolant, and a heat exchanger 8 for transferring heat from the loop 5 to a heat utilizing system 11. The secondary coolant is molten salt. The loop 5 installs a pressurizer 6 and a liquid separator 7 to maintain its pessure at atmospheric pressure to 10 barometric pressures or the like. The pressure in the heat exchanger 8 is substantially equal to that at the secondary side in the system 11 with almost no difference therebetween. Thus, the atomic reactor side coolant pressure can be selected to sufficiently high value, and the heat utilizing system pressure can be arbitrarily selected from the atmospheric pressure to the atomic reactor side pressure.

Title: Inter-multistation communication system
Inventor: INOUE TATSURO
IPC: H04L12/42
Filed: 1989-03-27
Abstract: PURPOSE:To attain normal detection of collision even when there is a difference from transmission power of each communication station by providing a transmission control means and a transmission reception means bringing a signal relay means capable of switching into the open state when its own station sends a signal. CONSTITUTION:When a communication station T1 makes transmission, the transmission is started for a period when no signal is received by a reception unit R. In this case, the station T1 uses a transmission control section CONT to throw a switch SW to the position of a contact (b). Then the transmission of the signal is started and before the signal and from the station T1 reaches a communication station T3, when the station T3 sends the signal, both switches SWs of the stations T1, T3 are thrown to the position of a contact (b). Thus, the transmission of the transmission signal of the station T1 is blocked by the station T3 and the transmission of the transmission signal of the station T3 is blocked by the station T1. Then the presence of collision between the stations T1, T3 and other communication station is detected. Even when there is a difference between transmission power of each communication station, the collision is detected normally.

Title: Film thickness measuring instrument
Inventor: NAKAJIMA TOSHIRO
IPC: G01B11/06
Filed: 1991-04-08
Abstract: PURPOSE:To enable the title instrument to highly accurately measure the thickness of a film without receiving any influence from line vibrations by simultaneously utilizing the light absorbing characteristic of the film in a visible light region and an intra-film multi-reflection phenomenon in an infrared region and simultaneously measuring the thickness of the film at the same point, and then, taking the product of both measurements. CONSTITUTION:The light of a light source 1 is partially branched by a half mirror 2 and only the component of the light having a specific wavelength intensity set by a wavelength filter 3 is monitored with a detector 4. The light transmitted through the filter 3 passes through a sample 5 and is again branched by a half mirror 6. The component of the light having the same wavelength as that the filter 3 has is made incident to a photoreceptor element 8 by means of a wavelength filter 7. The light transmitted through the mirror 6 is scattered by means of a diffraction grating 11 and forms images on a line sensor 12 in the order of the wavelength. The outputs from the detector 4 and element 8 enter a divider 15 after they are amplified by means of amplifiers 13 and 14 and are fed to a computing element 19 which calculates the film thickness of the sample 5 through a log amplifier 16. The output of the sensor 12 is compared with the data of an inter-peak wavelength-film thickness look-up table by means of a computing element 22 and the film thickness is identified. A multiplier 23 finds the product of both film thickness values and a computing element 24 outputs the real film thickness value by finding the square root of the product.
