Title: Controller of oil hydraulic system
Inventor: YAMAGUCHI TAKESHI
IPC: E02F9/22
Filed: 1980-12-27
Abstract: PURPOSE: To rapidly operate motor stopping means, by communicating a pipe line, linking an oil hydraulic pressure source to the motor stopping means, to the inside of a servo valve only when an oil hydraulic servo mechanism and oil hydraulic servo mechanism input means are both in a neutral position.  
     CONSTITUTION: In case of returning a control lever 30 of a servo valve 10 to a neutral position, though a selector valve 13, interlocking to the servo valve, is also returned to a neutral position, suction side pressure of an oil hydraulic pump 1 rapidly rises to operate a control valve 11, then the servo valve 10 can not be reset immediately to its neutral state and remain in a state of selecting position. When the servo valve 10 is in a neutral position, that is, when the oil hydraulic pump 1 is in a neutral state and an oil hydraulic motor 2 is in a substantially stopping state, the selector valve 13 is also in a neutral position, then pipe lines C 1 , C 2  are communicated through a casing 27, seleeve 28, spool 29 of the servo valve 10 to release working pressure of a brake device 20 to a tank, thus the brake device 20 can be operated.

Title: Ferrite laminate
Inventor: NONAMI TOORU
IPC: C04B37/00
Filed: 1989-07-19
Abstract: PURPOSE:To improve the stability of the interface between joined soft ferrite sintered bodies and the bonding strength without deteriorating the magnetic characteristics by joining the soft ferrite sintered bodies by superplastic working. CONSTITUTION:Soft ferrite sintered bodies are laminated and pressjoined by a superplastic working. The working temp. is usually regulated to about 600-1,200 deg.C and press joining is carried out at about 0.01-50mm/min rate of compression under about 1-100MPa compressive stress so that the deformation brings about 0.01-1.5 true strain. The-joining time is regulated to about 1-20min. The pref. average grain size of each of the ferrites in the resulting laminate is about <=30mum. The ferrites used may be the same ferrite or ferrites different from each other in Curie point, etc. Since the interface between the sintered bodies cause a solid phase or a diffusion joining by the press joining, the stability of the interface is improved.

Title: Optical recording and reproducing device
Inventor: MAZAKI YUTAKA
IPC: G11B21/08
Filed: 1988-07-26
Abstract: PURPOSE:To prevent burning due to the heating of a coil from being generated and to accelerate access by varying the level of a driving signal or that of reference speed corresponding to the temperature change of a movable coil in an objective lens driving device. CONSTITUTION:The change of a voltage division value between a thermistor 110 and a resistor 216 due to the temperature change of the movable coil 10 is A/D-converted at an A/D converter 206, and is inputted to a control circuit 210. The control circuit 210 varies a digital value outputted from a D/A converter 213 corresponding to the inputted temperature of the movable coil 10, and supplies a large magnitude of driving current when the temperature of the movable coil 10 is less than a prescribed reference temperature and a small magnitude of driving current when the former exceeds the latter to tracking coils 12A and 12B, respectively. In such a way, the speed of a light spot when a large level of driving current flows is increased more than that when a small level of driving current flows, thereby, the access can be accelerated.

IPC: H04N5/335
Filed: 1982-10-25
Abstract: PURPOSE:To perform optical AGC operation with a sufficient function by providing every photosensitive picture element with a circuit which detects the amount of charge of every photosensitive picture element and generates a voltage corresponding to the amount of charge, and connecting its circuit output to an MOS transistor (TR) for every picture element. CONSTITUTION:When photosensitive picture elements 2a-2n are irradiated with light, signal charges are generated corresponding to the intensity of the light and the amounts of charge are detected by potential detection parts 21a-21n to generate corresponding voltages. Those voltages are applied to MOS TRs 22a-22n at source electrodes and an external reference voltage VREF is aplied to gate electrodes to generte a potential barrier thereunder; when the amount of charge of some photosensitive picture element increases until the voltage detected by the potential detection part becomes below the potential barrier, a current flows to the drain of the MOS TR. A transfer gate 3 is opened by the driving pulse to move signal charges generated by the photosensitive picture elements 2a-2n to a CCD register 4, thus achives the optical AGC function.

Title: Production of ink-jet printer head
Inventor: KONO ICHIRO
IPC: B41J2/135
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a production method of an ink-jet head, capable of forming a large number of ink ejecting nozzles with a correct shape in an orifice plate collectively and homogeneously in a short time. SOLUTION: After a sticking a film for the communication prevention to the rear surface of a substrate, it is placed on a water fixing stage 62 of a helicon wave etching device. While circulating an anti-freezing liquid from a supporting base 63 into the wafer-fixing stage 62 by a low temperature circulator 65, a coolant gas 66 for promoting the heat conduction is sent into a minute gap (h) generated between the wafer fixing stage 62 and the substrate by a coolant sending pump 67. By the constitution, temperature rise of the substrate is restrained effectively at the time of helicon wave dry etching.  Since the film for the communication prevention to the substrate rear surface prevents upward blowout of the coolant gas 66 from an ink ejection nozzle 44 when the ink ejection nozzle 44 is formed so as to maintain the cooling state of the substrate, overetching operation can be continued in this state to finish the formed hole into a desired correct shape.

Filed: 1989-07-20
Abstract: PURPOSE:To enable accurate correction of the current position of a moving object even when the moving object runs off a road on a map by searching a road within a range in the perimeter of the current position on a road map to extract a data thereof. CONSTITUTION:A map accessed properly is projected on a screen of a display device 7 while the current position on X-Y coordinates is determined every second by a computation with a signal processor 3 according to a running of a moving object. The results of the computation are sent to the device 7 sequentially while being fed to a moving locus memory 4 to be stored and held. The contents of the memory are always read to be sent to the device 7 continuously. Here, a deviation between a data value of a position involved in a road of the map in which digital information is stored and a data value of a running locus of the moving object is judged with a device 3 under a fixed reference. When the deviation grows larger than a fixed reference, the current position of the moving body displayed on the map and a running locus thus given are corrected automatically to be always on the map according to a data value of the road.

Filed: 1983-10-04
Abstract: PURPOSE:To obtain an electrode for a fuel cell which has a good gas permeability and therefore causes a small reduction of electrode characteristics at a high current density by using an electrode base material prepared by fluorinating a perforated porous carbon material. CONSTITUTION:A conductive gas-permeable electrode base material 1 is prepared by performing water repellent treatment on a perforated porous carbon material such as carbon paper by heating it either in an atmosphere of a mixture gas composed of fluorine gas and an inactive gas such as CF4, He, Ar or N2. Next, a paste containing both PTFE used as a binder and a catalyst consisting of carbon powder particles containing fine platinum particles in their surfaces, is applied to the above electrode base material 1 to form a catalyst layer 2. After that, the thus obtained body is subjected to thermal treatment in an atmosphere of an inactive gas such as N2 at a temperature of 300-350 deg.C, thereby making an electrode for a fuel cell. Since the electrode base material 1 is prepared by making carbon paper itself water repellent by fluorinating it, there is no possibility that the fine holes are blocked with the water repellent agent and a high gas permeability is maintained.
