IPC: G01N33/543
Filed: 1987-02-05
Abstract: PURPOSE:To achieve a higher analysis accuracy in a reaction of a sow speed and a multi-stage reaction, by inserting a non-liquid permeable film detachably between a reagent layer and a development layer. CONSTITUTION:Reagent layers 1 and 2, a non-liquid permeable film 4 and a development layer 3 are laminated sequentially to produce a multi-layer analysis element. The film 4 is provided with a removing handle 40. For example, the reagent layer 1 is a regenerative cellulose film which contains glucose, glucose oxidase, 4-antiaminopyrine and 1,7-dihydroxy naphtharene, the reagent layer 2 a microfilter with modified human IgG immobilized and the development layer 3 a regenerative cellulose film. A mixed solution of an anti-human IgG labelled by peroxidase and a human serum (sample) are spotted on the multi- layer analysis element to react for 30min. Thereafter, the non-liquid permeable film 4 is removed to measure absorbance of reflected light on the side of the reagent layer 1.

Abstract: PROBLEM TO BE SOLVED: To provide a vacuum valve provided with a contact capable of simultaneously improving the contact resistance characteristic and the restriking characteristic. SOLUTION: In a vacuum valve to shut off/conduct the current by opening/ closing a contact in the vacuum, a  W-CuxSb-balance Cu} alloy is adopted as the contact, 65-85% W or WMo which is 0.4-9 μm in grain size is adopted as an arc resistant component in this alloy, and 0.09-1.4% CuxSb which is 0.02-20 μm in grain size is adopted as the auxiliary component, in which x=1.9 to 5.5, and its means grain spacing is 0.2 to 300 μm. In addition, Cu and CuSb solid solution is adopted as a conductive component, and the quantity of Sb present in the CuSb solid solution in a solid-solution state is set to be <=0.5%.  As a result, when the arc is received, vaporized CuxSb is less scattered, generation of harmful and remarkable cracks is suppressed in generating the restriking, scattering and detachment of W particles are also reduced, the melting and scattering damage on the contact surface are reduced, and the suppression of the restriking and the contact resistance characteristic are also improved.

Title: Display driving circuit
Inventor: SHOJI KAZUO
IPC: G09G3/30
Filed: 1988-02-04
Abstract: PURPOSE:To prevent damage due to the overloaded state of a circuit at the time of powdering on by not giving a write potential to scanning electrodes in the period when the display operation cannot be stably performed after powering on. CONSTITUTION:In a scanning-side driver IC of a thin film EL display device, the output of a reset circuit 17 is kept in a low level for a period T after powering-on until data store in a shift register 8 can secure the stable display operation. Consequently, the shift register 8 receives a reset signal in the low level and is reset in the period T, and its contents are set to the low level and a write voltage is not given from an output stage 12 to all scanning electrodes. Thus, the state that a write pulse and modulating pulse generating circuit, a DC-DC converter circuit, or the like is overloaded because of simultaneous application of the write potential to many scanning electrodes at the time of power-on or circuits are damaged by this overload is avoided.

Title: Winding parts and their winding method
Inventor: MOTOTANI KUNIJI
IPC: H01F41/06
Filed: 1995-02-14
Abstract: PURPOSE: To prevent disconnection accidents due to stress by slackening a lead wire for a coil. CONSTITUTION: In a winding part where a lead wire 2 is wound around a bobbin 1, a supporter 8 that can be broken by bending is provided projectingly in a wire leading part 5 of the bobbin 1 in such a way that a lead wire 4 for a coil can be hooked thereon. In addition, the supporter 8 is provided to protrode on the recessed part 7 formed in the part 5. Thus, after the lead wire is hooked on the support 8 and is connected with a terminal part, it is bent and removed, thereby slakening the lead wire. Therefore the lead wire can be prevented from reduction of diameter or disconnection, resulting in higher reliability of the winding parts. Further, even if a remaining base of the supporter 8 exists after bending and cutting, the lead wire is hardly hooked thereon because it is under the base surface of the wire leading part, thereby slakening the lead wire securely.

Title: Production of low-soda alumina
Inventor: SAKAI JUN
IPC: C01F7/46
Filed: 1989-02-06
Abstract: PURPOSE:To efficiently obtain low-soda alumina suitable as sparking plug insulators, etc., by mixing a raw material, containing Al(OH)3 and Al2O3 and prepared by the Bayer process, with a fluoride-containing soda removing agent and water, preparing compacts having a recessed groove, etc., stacking the compacts through thin sheets made of silica and calcining the stacked compacts. CONSTITUTION:A mixed raw material, composed of 20-70wt.% aluminum hydroxide and 80-30wt.% alumina and prepared by the Bayer process is prepared. A soda removing agent (e.g. a mixture of H3BO3 with AlCl3, AlF3 and CaF3) regulated to 40-80wt.% fluoride content in an amount of 0.8-2wt.% and water in an amount of 15-25wt.% are added and kneaded with the above-mentioned mixed raw material. The resultant kneaded mixture is subsequently formed to produce block compacts 1 having a recessed groove 2 or through-hole communicating with at least two surfaces. The compacts are then stacked through thin sheets 10 made of a siliceous substance so that the thin sheets 10 may face the recessed groove 2 or through-hole of each compact 1. The stacked compacts 1 are then calcined to afford the objective low-soda alumina.

Title: Common line signal control system
Inventor: KAMIJO AKINORI
IPC: H04L69/40
Filed: 1986-02-10
Abstract: PURPOSE:To prevent the quantity of retension transaction from being increased by providing a holding queue to a subprocessor system being a source of signal generation as well as a subprocessor system accommodating signal lines so as to decentralize a waiting signal thereby avoiding the concentration of a specific processor. CONSTITUTION:A signal link state control section 42 discriminates the presence of the necessity of temporary holding of a signal for line switching through the reception of a CSE event and a signal link control signal. When it is discriminated to require holding, its state is stored in a main memory device 33 of its own subprocessor system and the state is informed to a signal link state control section of other subprocessor subsystem via a CCA control section 3. The subprocessor subsystem receiving the notice stores its state in its own main memory device. When a signal routing section 1, in the state, receives a transmission request of a relay signal and a user signal, and when the signal is a signal addressed to a signal line requiring the temporary holding, each processor makes holding.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain constant operation performance at all times even when a load change of a mechanism part increases due to a different service temperature environment or individual variations. SOLUTION: An optical pickup 1 for recording or reproducing information on a disk A is driven by a traverse motor 2 via a power transmission mechanism 3. The motor is controlled by a controller 7.

Abstract: PURPOSE: To detect the thickness of a material stuck to the inside of a tube, comparing the estimated value of the temperature at the outlet of a furnace which is calculated from the temperature at the inlet of the furnace and the flow rate of a reactive  fluid plus the temperature of the atmospheric gas within the furnace with the actual  measurements.  
     CONSTITUTION: The temperature TC 1  at the inlet of a furnace and the flow rate W of  a reactive fluid are detected by a temperature detector 4 and a flow detector 5 respectively. At the same time, the temperature TC 2  at the outlet of the furnace and the temperature TH of the atmospheric gas within the furnace are detected by a temperature  detector 6 and a gas temperature detector 7 respectively. The detected value of each  of the detectors 4W6 is supplied to an estimate arithmetic device 8, and an estimated  temperature T'C 2  at the outlet of the furnace is supplied to a comparison operator 9.  On the other hand, the measured value of temperature of the detector 6 is supplied to  the operator 9, and the temperature T'C 2  is compared with the measured temperature  TC 2 . In case when the value TC 2  is lower than the value T'C 2 , the thickness of a matter  stuck to a tube 2 is decided larger than the reference level. Thus an alarm signal is delivered. In such way, the thickness is detected accurately for the matter stuck to inside  of a tube.
