Title: Thermal recording material
Inventor: OHASHI MIHO
IPC: B41M5/337
Filed: 1987-07-10
Abstract: PURPOSE:To ensure excellent oil resistance and plasticizer resistance of images and contrive higher reliability, by incorporating 3,4-dihydroxyphenyl-4'- methylphenylsulfone into an undercoat layer. CONSTITUTION:An undercoat layer and a thermal color forming layer comprising a leuco dye and a color developer as main constituents are provided on a base. The undercoat layer comprises 3,4-dihydroxyphenyl-4'- methylphenylsulfone. The compound is preferably used in an amount of 0.2-10g/m<2>. The amount of the compound is suitably 20-80% based on the undercoat layer. The thermal recording material is produced by applying a coating liquid for forming the thermal color forming layer comprising the constituents to an appropriate base such as a paper, a synthetic paper and a plastic film, followed by drying. The recording material is used in a variety of recording fields, particularly as a thermal recording material for high-speed recording for which high image stability is required. By utilizing the excellent stability of developed color images, the thermal recording material can be advantageously used as a thermal recording type label sheet or a thermal recording type magnetic ticket paper.

Title: Steering gear for crawler vehicle
Inventor: MINAMI TERUO
IPC: A01B69/00
Filed: 1987-07-10
Abstract: PURPOSE:To make the turning force conformed to the manipulated variable of a steering lever securable by detecting each rotational frequency at both driving and driven shaft sides of a friction coupling, and making the ratio of both sides during turning motion so as to become such a value that corresponds to the manipulated variable of the steering lever. CONSTITUTION:When a steering lever 25a is operated, a driving duty ratio D of the solenoid SOL1 conformed to the output value of a volume VR1 is read out of a read-only memory 32. When a clutch part alone operates at a steering gear, a duty ratio of the solenoid SOL1 is altered so as to cause a ratio Ra between speed sensors S1 and S3 to accord with a transfer ratio R being prestored in the ROM 32. When operating levers 25a and 25b are operated and each output of volumes VR1 and VR2 comes to the specified output, directional control valves 21a and 21b comes into a state of being situated in a position P2 or P4, thus a braking part operates.

Inventor: NISHINO TADASHI
IPC: B22D11/06
Filed: 1983-09-19
Abstract: PURPOSE:To obtain a light-gage hoop having excellent internal quality by press sticking the solidified shell formed on the surface of cooling rolls, detecting the loading load of the rolls arising therefrom and controlling the solidifying time within the spacing between the rolls so that the detected value attains a target value. CONSTITUTION:The rolling load P of a solidified slab 6 is detected by load detectors 9, 9' disposed on the rear surfaces of bearing boxed 8, 8' fixes by housings 12, 12' in the stage of forming a molten metal well between cooling rolls 3, 3' on the long side of a twin roll type continuous casting device and short side stationary plates 13, 13' consisting of refractories having small heat conductivity and press sticking the solidified shell 24 formed on the surface of the rolls 3, 3'. If the load P is large, the circumferential speed (v) of the rolls 3, 3' is increased and if the load P is small, the speed (v) is decreased to control the solidifying time in the spacing between the rolls and to control the press sticking length l to an intended value. The stable production of the light-gage hoop having excellent internal quality is thus made possible.

Title: Formation of thermal oxide film
Inventor: EBARA KOHEI
IPC: H01L21/304
Filed: 1992-06-08
Abstract: PURPOSE:To form a silicon thermal oxide film which ensures a longer life time and less amount of defects of silicon substrate by executing the final etching of the silicon substrate cleaning process with hydrofluoric acid and thereafter introducing the silicon substrate into an electronic furnace under the atmosphere where oxygen is reduced with nitrogen or inactive gas. CONSTITUTION:The wafer surface is changed to the hydrophobic state by processing a Si wafer after cleaning the surface thereof with ammonium, aqueous solution of hydrogen peroxide, water, hydrochloric acid, aqueous solution of hydrogen peroxide and water. The Si wafer of which surface is changed to hydrophobic state is then introduced into an electronic furnace under the atmosphere where oxygen is reduced by nitrogen or inactive gas. The Si thermal oxide film is formed by heating the Si wafer. In this case, it is prevented that air outside the quartz tube flows into the quartz tube by adjusting flow rate of gas in the quartz tube of the electric furnace, flow rate of gas in the quartz tube near the furnace and exhaust rate. Thereby, a purified thermal oxide film is formed on the silicon substrate and life time of the silicon substrate can be improved.

Title: Request acceptance processor
Inventor: OKETANI HARUHIRO
IPC: G06F9/46
Filed: 1990-07-02
Abstract: PURPOSE:To make it unnecessary for a process request source to repeat the redundant reissue of the request by suppressing the reregisteration of a control block corresponding to the process request source of a communication request received newly while the number of processes whose execution is not completed is beyond a prescribed monitored value. CONSTITUTION:A control block ECB 5 corresponding to each process request source 11 is registered in a synchronization controlling part 3 so that a request accepting part 10 of a processing part 2 can receive the request. When the process request source 11 issues the information request after designating the above mentioned ECB 5, the synchronization controlling part 3 transmits the information request to the request accepting part 10, and cancels the registration of the ECB 5. Then, the request accepting part 10 monitors the number of the processes whose execution is not completed, and stores the identification name of the process request source 11 in a waiting registering table 15 as the request source identification name while the number is beyond a prescribed monitored value 12. At that time, the reregistration of the ECB 5 is not operated. Thus, it is not necessary for the process request source 11 to repeat the redundant reissue of the request.

Title: Ion pump
Inventor: KAGEYAMA KATSUHIRO
IPC: H01J41/12
Filed: 1981-10-31
Abstract: PURPOSE:To enable enhancement of the exhaustion speed of an ion pump by distributing the kinetic energy of ion, which are incident upon cathodes, within an area of  a large sputtering ratio by controlling the electric potential of a discharge space by  means of a dischrge controlling electrode which extends from one of the cathodes to  the hollow space of an anode. CONSTITUTION:An electron group is developed in the hollow space 2 of an anode 1 by  the magnetic field of a magnet 13 and a cross electromagnetic field, which developes  due to the difference between the electric potentials of the anode 1 and cathodes 3.  Most of ions which are produced from gaseous molecules due to above electron group,  bump against the cathodes 3 without bumping against a discharge controlling electrode  15, and sputters a cathode-covering matter which consists of a getter member. The  anode 1 is earthed, the electrode 15 is given an electric potential, and the cathode 3 is given an electric potential lower than that of the electrode 15. Besides, the electric  potential of a discharge space formed in the hollow space 2 of the anode 1 is controlled  by the electrode 15. Therefore, the exhaustion speed of the ion pump can be increased  by increasing the sputtered amount of the getter member. In addition, by using collecting electrodes 4, a stable exhaustion speed can be realized even for a rare gas.
