Title: Reactor container
Inventor: KURIYAMA SHUICHI
IPC: G21C9/004
Filed: 1988-09-08
Abstract: PURPOSE:To lower the water level accumulating in a lower dry well and to prevent submergence of an electrical conduit, etc., by providing a return line which is opened at one end and is communicated with the other end into the pool water in a wet well to the dry well. CONSTITUTION:The water in a suppression pool 2 at the time of sloshing rises in the return line 20 and lifts a ball 21. The lifted ball 21 closes a hole 22 of an upper plate 23 attached with the taper toward the hole to prevent the water from flowing into the lower dry well 5. The ball closes the hole 22 of the upper plate 23 to prevent the water from flowing into the lower dry well. The pipe of the return line 20 is projected upward from the upper plate 23, by which the water passing the hole before the closure of the hole 22 by the ball 31 is prevented from flowing into the lower dry well and is dropped by gravity so as to return into the suppression pool 2. The installation of the return line 20 at the level lower than the sloshing level is enabled by such check structure. The submergence of the electrical conduit, etc., is thus prevented.

Abstract: PURPOSE:To reduce pinholes and microcracks, and improve a moisture and contamination resistance, and further, make a semiconductor device hard to be affected from the outside, by depositing a vapor growth oxide film on the wiring made of aluminum alloy directly, and by forming a nitride film thereon after performing an etchback. CONSTITUTION:On the principal surface of a single crystal silicon substrate 11, phosphorus glass film 12 is deposited, and thereon, a wiring layer 13 made of aluminum allay is formed. Thereafter, an interlayer insulation film 14 is formed by a CVD method. Then, by an anisotropic plasma etching method, the interlayer insulation film 14 is removed halfway, and thereon, by a plasma CVD method, a nitride film 15 is formed as a surface protection film. Further, when the film 14 having grooves, which are deep and have a tendency to overhang near their opening parts, is subjected to an etchback, its protruding parts are etched rapidly. As a result, the deep grooves and overhang parts are eliminated. Thereby, an irregular shape caused by a multilayer wiring structure is changed into a smooth surface shape, and there is no extremely thin part in the nitride film 15. Therefore, pinholes and microcracks are prevented from generating, and a moisture and contamination resistance can be improved.

Title: Speed change gear transmission device
Inventor: ONISHI HIDEAKI
IPC: F16H3/08
Filed: 1987-09-07
Abstract: PURPOSE:To decrease the length of a speed change key, to form a transmission case in a lateral symmetrical shape, and to reduce limitation on a layout, by providing speed change keys which are controlled and moved from both sides toward a speed change gear. CONSTITUTION:Speed change keys 5, controlled and moved from both end sides toward a central part side along a speed change shaft 4, are mounted to a speed change gear 3 disposed on a speed change shaft 4. Compared with a conventional type in which the speed change key is controlled and moved from the one side of the speed change shaft 4, in the case of the same number of gear shifting steps, the length of the speed change key 5 can be distributed to both sides, resulting in decrease of the length of the speed change key 5. Thus, twist of the speed change key 5 when transmission on the speed change shaft 4 through the speed change key 5 engaged with the speed change gear 3 is prevented from occurring, and the number of gear shifting steps can be increased on the whole. The speed change key is not widely protruded toward a transmission case incorporating an input shaft 1 and the speed change shaft 4, and in case the speed change gear transmission device is mounted, limitation on a layout is reduced.

Title: Local radio telephone system for disaster prevention
Inventor: AIZAWA MOTOYA
IPC: H04B1/02
Filed: 1990-08-28
Abstract: PURPOSE:To cut the output of a data tone reporting the end of transmission from a speaker by delaying a reception signal by a certain time and closing a gate means at a prescribed timing at the time of detecting a data signal. CONSTITUTION:The signal received by a transmission/reception part 1 is inputted to a signal delay part 2 and a data detecting part 3. The delay part 2 delays the input signal by a certain time and outputs it to a gate circuit 4. Normally, the circuit 4 is opened, and the radio signal outputted from the delay part 2 is outputted from the speaker through the circuit 4. When transmission of the other-party station is terminated thereafter, the data signal reporting the end of transmission is received and is outputted to the delay part 2 and the detecting part 3. The detecting part 3 detects reception of this data to close the circuit 4 through a control part 6 at the end timing of output of the sound signal. Consequently, the data signal outputted from the delay part 2 following the sound signal is stopped by the circuit 4 and is not outputted from the speaker 5.

Title: Control circuit for linear motor
Inventor: MARUYAMA SHIGEHISA
IPC: H02P25/06
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To obtain a control circuit by which the position detection and the position control of a linear-motor moving part are performed stably without using a position detecting sensor by detecting an induced voltage which is generated in a driving coil when an induced-voltage detection means moves the linear- motor moving part. SOLUTION: On the basis of a change in an induced voltage generated in a driving coil Rd, an induced-voltage detection means 110 outputs an output voltage which is proportional to the speed of a moving part 3. A speed servo loop 160 processes the output voltage by using a filter amplifier 120 so as to create a processing voltage. In addition, an integrator 135 integrates the output voltage so as to be converted into a position signal which expresses the position of the moving part 3. In addition, a position servo voltage is created on the basis of the comparison of the position signal with a target signal.  Then, when a driving amplifier 145 supplies a voltage signal to the driving coil Rd and to a resistance R3 on the basis of the position servo voltage, a linear motor M moves a moving lens 12 up to a target position which is given by a target- position signal, and it positions the lens. Thereby, a position detecting sensor is not required.

Title: Improver for ground, structure, or the like and method for improvement using the same
Inventor: DANIERU GUBUANO
IPC: C09K103/00
Filed: 1986-09-22
Abstract: PURPOSE:To obtain the title improver of one-pack liq. type exhibiting long gel time and capable of providing a high strength, by adding a monovalent alkali metal and calcium carbonate to an alkali silicate. CONSTITUTION:An improver prepd. by adding a monovalent alkali metal hydroxide and calcium carbonate having a particle size of 20mum or less to M2O.nSiO2 (wherein M is a monovalent alkali metal). Although Na, K, Li or the like can be used as the alkali metal to be added, Na is most suitable. The added alkali metal ionizes the silicate to give an activated alkali silicate (or a salt of silicic acid). The SiO2 to Na2O molar ratio of the silicate is pref. 0.7-2.0, particularly pref. 0.7-1.5. When the molecular ratio exceeds 2.0, the reaction of the silicate with calcium carbonate is insufficient, which makes it difficult to prepare excellent crystals. When consideration is given to the dispersibility of calcium carbonate and the preparation of an improver capable of providing a higher strength than that provided by conventional improvers, the molar ratio is pref. lower than 1.5.
