Inventor: HAYASHIDA KATSUHIKO
IPC: F25B41/04
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of an under-mentioned trouble since the volume of a valve body is increased and it is a factor by which the increase of the number of processing processes is caused because of a space for an exclusive use for a subvalve to effect opening and closing drive of a main valve in an on - off valve and a communication port being needed by the valve body. SOLUTION: This on - off valve for a refrigerating cycle device is worked to open and close the hole 1g of a valve seat 19 through drive of a main valve 4 by a pressure difference between a pressure P1 at the inflow part 2a of a valve body 1 and a pressure P2 in a space 1c formed closer to a first communicating port. Especially, a subvalve chamber 9d and a first communication port 9a are formed in a cover body 9 mounted on the external opening part 21 of the main valve chamber 1a, and a second communication port 17 comprises a body port 1d formed in the valve body 1; and a cover body port 9b formed in the cover body 9 and communicated to the body port 1d.

Title: Manufacture of semiconductor integrated circuit
Inventor: FUJITA TSUTOMU
IPC: H01L21/3205
Filed: 1986-11-06
Abstract: PURPOSE:To form a metal wiring part and an interlayer insulating film, without a void, and to make them flat by selectively growing a metal only at a recessed groove formed at the insulating film. CONSTITUTION:The interval between adjacent recessed grooves 2 for a metal wiring part is of the submicron order. Polycrystalline silicon 3 is deposited on the whole surface by a CVD method. The whole surface of this assembly is coated with a resist film 4; by means of an etching-back method the resist 4 remains only at the grooves 2. The polycrystalline silicon 3 is etched by making use of the resist 4 as a mask so that the polycrystalline silicon 3 remains only on the bottom and the side of the grooves 2. The polycrystalline silicon film 3 is made to react with a gas which has been formed by diluting WF6 with Ar. By making use of a silicon reducing-reaction, tungsten (W) 5 is grown selectively only on the side and the bottom of the recessed grooves 2. Because hydrogen tends to be adsorbed to the surface of a metal and to be ionized during this process, the grooves 2 are buried with the tungsten (W) 5 completely. Because this hydrogen reducing-reaction is completely a surface reaction, the growth is isotropic and no void is grown. As a result, the close adhesiveness of the tungsten (W) 5 at the polycrystalline silicon 3 is enhanced, and the tungsten (W) 5 is never exfoliated.

Title: Thin film magnetic head
Inventor: SASAKI TOYONARI
IPC: G11B5/31
Filed: 1985-11-27
Abstract: PURPOSE:To prevent the deterioration of characteristics of a thin film magnetic head due to the effect of an external magnetic flux, by forming an upper or lower magnetic layer into such a form where the magnetic resistance of the magnetic gap side is lower than that of the connection side between the upper and lower magnetic layers. CONSTITUTION:The thickness of a lower magnetic layer 11 is increased at the position closer to a magnetic gap 6 for formation of a thick part 11a. While a thick part 3a is also formed to an upper magnetic layer 3 at the position toward the gap 6. The areas for both parts 3a and 11a are limited in a range closer to the gap 6 from the center part of a coil conductor 2. Thus the magnetic fluxes C are produced and pour on within both layers 3 and 11 as shown by arrow heads. Then the magnetic resistance is reduced at the parts 3a and 11a and the magnetic fluxes flowing to these parts are increased. As a result, a null plane A moves toward a contact part 4. Thus only the magnetic fluxes jumped to the part 4 from the plane A link the conductor 2 in a reproduction mode. This attains reduction of crosstalks.

Title: Smoke monitoring system
Inventor: YOSHIKAWA YOSHIRO
IPC: G08B17/10
Filed: 1989-10-12
Abstract: PURPOSE:To prevent a warning from being generated by smoke due to smoking and further to speedily detect the abnormal increase of smoke density due to fire, etc., by judging whether the smoke density is abnormal or not while changing a threshold value corresponding to a smoking state or the ventilating state of a room. CONSTITUTION:A smoke density detecting means 3 detects the smoke density in the room as a monitoring object and outputs a smoke density signal and a smoking person number output means 4 outputs a smoking person number signal expressing the number of smoking persons in the room. Then, a ventilat ing state output means 6 outputs a ventilating state signal expressing the venti lating state of the room to a control means 5. At first, the control means 5 determines the threshold value based on the smoking person signal and the ventilating state signal. Next, the determined threshold value is compared with the smoke density expressed by the smoke density signal from the smoke density detecting means 3. When the smoke density is more than the threshold value, an abnormal signal is outputted to a warning means, etc., for example. Thus, the abnormality of the smoke density can be monitored while considering the smoking state or the ventilating state, as well.
