Title: Preventing stress corrosion crack in boiling light-water reactor
Inventor: SHIYOUJI SABUROU
IPC: G21D5/06
Filed: 1977-11-04
Abstract: PURPOSE: To prevent stress, corrosion and crack of the reactor, by adding Li 7 OH to the primary cooling water, with lithium (Li 7 ) type ion exchange resin applied to a desalter of reactor clean system, to keep the primary cooling water in alkaline state of pH8 to 10.  
     CONSTITUTION: For a pH tempering compound of primary cooling water in the boiling light-water reactor, for instance, LiOH, NaOH, KOH, etc. will be used. The cooling water is always exposed to a strong radiation. As a material, with addition agent not secondaryly activated, not seized by a desalting device in the core clean system to purify a slight amount of impurities with the core made partially bypassing, and relatively easy to be procurable, the most suitable is Li 7 OH. Li 7 , with a secondary activity not charged, by using lithium type (Li 7 ) ion exchange resin to the core clean system desalting device, because of no consumption of Li 7 OH in the cooling water, will be suitable for pH tempering alkaline compound.

Title: Method for finding and tracking positions of direct access memory device, disk drive and track
Inventor: KEBUIN JIYATSUKU ERITSUKUSON
IPC: G11B21/08
Filed: 1993-06-02
Abstract: PURPOSE: To obtain an excellent track follow-up error correction signal without a need for a long burst by identifying a servo burst with a maximal amplitude in amplitude information from an amplitude demodulation circuit, and also identifying a servo burst nearest to a center line of a reading data sensor from a phase of a maximal amplitude burst from a phase demodulation circuit. CONSTITUTION: This device is used for a purpose that amplitude information from an amplitude demodulation circuit 52 identifies a servo burst with a maximal amplitude. And, this method is used for identifying which servo burst is the nearest to a center line of a reading data sensor, from the phase of the maximum amplitude servo burst from a phase modulation circuit 50. At the same time, the circuit 52 provides fine position information which is only a track follow-up error, by comparing relative servo burst amplitudes. Thus, same amplitude information as that in a typical amplitude burst system is obtained from the circuit 52 during track follow up, and an excellent correction signal is obtained for track follow-up error.

Title: Prescribed position stop control system considered with operating time
Inventor: YASUNAMI MASAHIRO
IPC: B60L15/40
Filed: 1980-09-24
Abstract: PURPOSE: To effectively regulate the delay or advance of a train by selecting the deceleration of the stopping pattern for controlling the stoppage at the prescribed position in response to the degree of the delay or advance of the operating time of the train.  
     CONSTITUTION: A data discriminator 3 identifies the delay or advance of the information transmitted from the ground with respect to a schedule. A position receiver 6 detects a ground element installed in the vicinity of a station. A prescribed position stop control stop pattern generator 4 outputs a stop pattern selected by the output signals of the data discriminator 3, the position receiver 6 and a tachometer generator 7. A proportional controller 9 outputs the deviation between the stop pattern and the speed signal. This output is converted to the output of a relay or the like in the output unit 10 and is thus outputted, thereby stopping the train automatically to a station while following up the stop pattern for controlling the stop of the train at the prescribed position.

Title: Paste for surface conductor of low temperature baked-up multilayer substrate
Inventor: TANIGUCHI YOSHIAKI
IPC: H05K3/46
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a paste which can be baked up simultaneously and generates no peeling-off and no lifting-up by using a specific conductive metallic powder and TiO2 powder in a specific volume ratio. CONSTITUTION:A conductive metal is selected from Ag, an Ag/Pd alloy, Au, Cu, and an alloy mainly of Cu. The particle diameter of the metallic powder is selected at about 2 mum, while the particle diameter of the TiO2 is selected at 1/8 to 1/20 of that of the metallic powder. As the TiO2 powder, the rutile structure is preferable. By setting the volume ratio of the metallic powder and the TiO2 between 9/1 and 6.5/3.5, and making the TiO2 to occupy 10 to 35 % of the main component powder, the sintering time of the metallic particles is delayed approaching to the sintering time of the substrate, and consequently, peeling-off and lifting-up of the paste is eliminated. The TiO2 is made into a cubic mesh structure finding each other, the strength of the sintered membrane is improved, and its close adhesion to the substrate owing to the intrusion to the substrate is also improved.

Title: Fuel combustion device
Inventor: MIYAHARA KINGO
IPC: F23D14/66
Filed: 1988-05-30
Abstract: PURPOSE:To enable a smooth starting of combustion and a stable gasified combustion to be continued for a long period of time by a method wherein each of a fuel pipe having a fuel discharging part therein and an air blowing pipe for supplying a heating air into a mixture gas generating pipe is connected in a branch form to a base end of the mixture gas generating pipe through a merging part. CONSTITUTION:An air blowing and heating heater 107 is energized. As an air is blown into an air blowing member 106, the air passes through a merging part 103 and is circulated within a mixture gas generating pipe 101, thereafter the air is sent into a lower combustion pipe 108 than a communication passage 113. The air is forcedly injected from several flame injection holes 111 toward the upper part mixture gas generating pipe 101. Since each of a fuel pipe 104 having a fuel discharging part 105 for injecting fuel installed therein and an air blowing pipe 106 for use in blowing hot air is arranged in a branch form through an interface of the merging part 103, the fuel discharging part 105 may not be directly exposed to hot air, resulting in that an intermittent discharging phenomenon or expanded deformation may not be generated and a predetermined amount of fuel can be injected continuously to the merging part 103. In addition, the heated air does not heat the fuel discharging part 105 and the heated air is not decreased at its temperature and so a stable gasified combustion can always be continued.

IPC: B60T7/06
Filed: 1977-11-04
Abstract: PURPOSE:To provide an apparatus which checks the retraction at the starting on the slope while preventing the parking brake from being locked when it is operated while running by allowing the locking of the parking brake when the engine revolutions exceeds a given value. CONSTITUTION:When a step is given to a pedal section of a lock arm 33 together with a brake pedal 28 for parking a golf car or the like, a retaining pawl of a lock arm 33 is engaged with a locking hook 37 thereby checking the return of the pedal 28. This allows the brake device as not illustrated to be maintained in a state of braking. Under such a condition, as revolutions of the engine increase gradually with the acceleration pedal depressed for starting, a centrifugal force works to move a centrifugal weight 45 in a revolutions detection mechanism 41 to be driven in synchronization with the engine 6 to the position as shown by the chain line, pushing a sliding shaft 47 outward. Thereupon, the lock arm 33 is turned forward through a lever 51, a wire 40 and a lever 38 causing the locking to be released.
