Title: Reactor for hydrogen storage alloy
Inventor: KUBOTA HITOSHI
IPC: F17C11/00
Filed: 1988-03-18
Abstract: PURPOSE:To provide the title reaction tank so designated that plural trays are installed within a reaction tank and a hydrogen-occlusive alloy is put to each tray, thereby improving the penetrability of H2 gas into the alloy layer and preventing the reaction tank from breaking failure due to the expansive force of the alloy. CONSTITUTION:The objective reaction tank 1 with its section roughly cylindrical, is comprised of the lower and upper tanks 1a and 1b, the tank 1a being fitted with a ring 9, on which a tray 3d made of e.g. aluminum alloy is mounted. The interior of the tray 3d is provided with a coil pie for cold heating 4 to pass a coolant from a tank 12 via the tank 1a, the upper end of said pipe 4 is connected with a second pipe 4 in a tray 4c. Similarly, the tank 1b is also provided with trays 3a-3c and pipes 4, and a hydrogen-occlusive alloy 7 is put into each tray 3. When H2 is introduced from a line 11 into the tank 1 said gas enters, as the arrow B along with the arrow A, the respective trays 3 and penetrates through the surfaces of the alloy layers 6 in the respective trays 3 into their interiors. Thus, the penetrability of the H2 gas into the layers 6 is improved, thereby protecting the wall of the tank 1 from damage due to the expansion of said alloy.

Title: Controlling method for rotor
Inventor: NAGAHATA MASASHI
IPC: B64C11/00
Filed: 1990-03-16
Abstract: PURPOSE:To enhance foul/flutter characteristic without increasing the weight of an engine nacelle structure by lowering rigidity in such a manner as further lowering one with low characteristic frequency of frequencies of the coupled modes of pitching and yawing series as to foul/flutter characteristic. CONSTITUTION:Stability analysis of foul/flutter is carried out by closed-loop control law in which the aerodynamic force of a propeller calculated by an external program 21 is feedback to an engine nacelle structure 22 by detection of the displacement and the angular velocity of a propeller hub. When the foul/flutter characteristic of the nacelle structure is bad at the initial stage of designing, only rigidity related to one with small frequency of coupled modes (pitch and yawing) is lowered so as to increase frequency. By this constitution the foul/flutter characteristic is enhanced while the weight of the structure is reduced.

Title: Applicator
Inventor: NARUSE YASUTO
IPC: B05C5/02
Filed: 1983-04-14
Abstract: PURPOSE:To inhibit the formation of stripes, troubles, etc. even when a liquid having a low liquid contact angle or low viscosity is used as a coating liquid, by applying water-repelling resin onto the top end of a hopper-type applicator. CONSTITUTION:Water-repellint resin 9, e.g. fluororesin polyacetal resin, is applied onto the top end of an applicator head 3 at the lower end of a slide surface. Hence, the falling-in of a coating liquid at the lower end of the slide can be inhibited by the effect of water repellancy, even when a degree of vacuum in an evacuated chamber is enhanced during high-speed thin film application. The turning of said liquid to the outside of a web can also be inhibited at the same time.

IPC: H04Q3/545
Filed: 1989-03-20
Abstract: PURPOSE:To improve the reliability of test and diagnosis by applying judgement whether or not interrupt as a response in a test.diagnosis command is a correct interrupt. CONSTITUTION:A coincidence detection means 21 is started when a channel controller 12 detects the production of an interrupt request REQ as a response with respect to a test.diagnostic command CM from a central controller 11. Then an address 10A specific and assigned in advance to an input and output controller 13 being an object to the test.diagnostic command CM is fetched by a channel bus 14 and the address specific and used to other interrupt is fetched from an internal bus 16 side and when the coincidence of both the specific addresses is detected, the result is informed to a central controller 11 as a correct interrupt signal INT. Thus, the production of erroneous test.diagnostic result is avoided.

Abstract: PROBLEM TO BE SOLVED: To detect the end point of vapor phase chemical etching with high accuracy by deciding the finishing time for patterning, based on a divided signal which is obtained by dividing the luminous intensity of a prescribed wavelength by the luminous intensity of a wavelength having a prescribed width. SOLUTION: An optical sensor 181 outputs a voltages VL1 and VL2 respectively, corresponding to a total luminous intensity L1 of a wavelength between 300 nm and 800 nm and a specific luminous intensity L2 of a wavelength between 650 nm and 660 nm. The dividing section 196 of a control section 191 generates a divided voltage VL2/VL1, by dividing the voltage VL2 by the other voltage VL1, detects the slope of the divided voltage VL2/VL1, and generates a differential signal S. The deciding section 197 of the control section 191 decides the end point of a vapor phase chemical etching, based on the differentiation signal S and terminates the etching and ashing by stopping the outputs from high-frequency sources 121 and 161. Therefore, a semiconductor device having good elemental characteristics over a large area can be manufactured, by accurately detecting the end point of the etching.  In addition, the end point of the etching on various kinds of materials can be detected accurately.

Filed: 1988-03-18
Abstract: PURPOSE:To attain the transmission while the transmission power for each carrier is adjusted to a prescribed automatically by allowing a reference value change circuit to revise the reference value of a power amplifier circuit based on the on/off information if the on/off state of the transmission unit is changed. CONSTITUTION:An ON/OFF command signal raised from the control circuit 2 is sent to a conversion table circuit 11. Then the circuit 11 gives a reference data Pm' corresponding to the ON/OFF state based on the reference list of a ROM to a reference value generating circuit 9. A comparator 8 compares a reference value Pm inputted from the reference generating circuit 9 with the detection output inputted from a detector 7 to control the attenuation of the variable attenuator 4 so that they are made coincident thereby, applying automatic level control of the transmission power. Thus, even if the on/off state of channel units 11-1n is changed, the transmission power per each carrier is always kept constant.
