Title: Unattended running vehicle system
Inventor: SAKAIRI NATSUHIKO
IPC: G05D1/02
Filed: 1990-03-30
Abstract: PURPOSE:To control the speed, the destination, or the like of a vehicle without a special communication equipment by mixing currents having plural frequencies to supply them to a guide path wire and discriminating them on the side of the unattended running vehicle. CONSTITUTION:A central processing unit 7 outputs a speed control signal indicat ing stop, high-speed running, high-speed running of an unattended running vehicle 5 and a stop position signal indicating the stop position as an instruction S, and an oscillating circuit 6 outputs a speed control signal V and a destination designating signal P in accordance with the instruction S. A guide signal oscillating circuit 4 oscillates an AC signal A for unattended running vehicle guide, and a frequency mixing circuit 3 superposes signals V and P on this AC signal to output a superposed signal CS. An unattended running vehicle 5 detects the superposed signal CS from a guide path wire 1 through pickup coils 101 and 102, and the AC signal A as the steering control signal, the speed control signal V, and the stop position designating signal P are separated by a frequency discriminating circuit. Thus, an unattended running vehicle system is obtained where the guide line 1 is more used to improve the convenience for use.

Title: Gamma correction circuit
Inventor: NAKAMURA HITOSHI
IPC: H04N5/202
Filed: 1992-04-06
Abstract: PURPOSE:To adjust the saturation without changing the gamma characteristic by applying an image pickup signal to a saturation adjustment circuit in which a low input level is subject to emphasis processing, applying the processed signal to a gamma correction section in which gamma correction is implemented to the image pickup signal. CONSTITUTION:An output level alpha or over is limited by a limiter 22 of the gamma correction circuit 10, a 1st limiter output (f) is obtained, an image pickup signal (e) is halved by an attenuator 24 and its signal (g) is limited for the output level alpha or over by a limiter 25 and a 2nd limiter output (h) is obtained. Both the outputs f, h are subtracted by a subtractor 26 and the gain of a correction signal (i) is adjusted by an amplifier 27 and the result is synthesized onto the current image pickup signal (e). A synthesis image pickup signal (j) includes a detection signal (i) for saturation adjustment and the signal is fed to a gamma correction section 30. Only a low input level of the gamma correction signal d' lower than a 1st inflexion point (x) is changed and unchanged entirely at a level higher than the level. The saturation is adjusted at the low input level. The amplitude of the correction signal is changed by controlling the gain of the amplifier 27 from an external control terminal 28 in the adjustment of the saturation to adjust the saturation.

Title: Production of aluminum nitride substrate
Inventor: KUBOTA MASA
IPC: C04B35/58
Filed: 1991-03-25
Abstract: PURPOSE:To offer the method for producing an aluminum nitride substrate having high insulation resistance, especially as high as >10<13>OMEGA.cm. CONSTITUTION:In the production process of an aluminum nitride substrate from aluminum nitride powder, alumina powder and carbon powder as the main source material, the carbon powder used has 1-10mum average particle diameter and the adding amt. of the carbon powder is specified to the range represented by an area A-B-C-D in figure 1. This method gives a significant effect to easily produce an aluminum nitride substrate having not only good thermal conductivity but >1013OMEGA.cm insulation resistance. As a result, this production method requires no inspection or selecting process and gives a higher yield compared to a conventional method which causes large variation in insulating resistance of products. Moreover, while a low oxygen-contg. AIN powder alone is used as the source material by the conventional method considering the thermal conductivity of the substrate, by this method, such a kind of problem can be eliminated.

Title: Ac 2-line system contactless switch
Inventor: WATANABE YASUYUKI
IPC: H03K17/94
Filed: 1981-06-03
Abstract: PURPOSE:To pretect an internal circuit from being damaged when excessive current flows by connecting a voltage detecting circuit to detect that a constant  current circuit consisting of transistors and resistances operates. CONSTITUTION:At normal operation, a transistor TR9 maintains off status during the period a detecting signal (b) is ''L'', and current flows from an AC zero point into a load 3. When the load 3 is shorted, the voltage applied to both the ends of a resistance 15 is quickly increased and the base current of a TR6 starts to flow through a TR7. Since impedance between the collector and emitter of the TR6 is increased at that time, the collector and emitter of the TR6 is increased at that time, the voltage of a point (a) rises, current flows through SSS12, the TR9 is turned on, and TRs 8, 6 are turned off. When excessive current is going to flow into the TR6, the TR6 is turned off at the time of constant current, protecting the TR6 from being damaged.

Filed: 1990-03-30
Abstract: PURPOSE:To obtain device threshold voltage based upon voltage on an output terminal between first and second FETs by operating the first FET in a saturated region and the second FET in a non-saturated region. CONSTITUTION:Two normally-on type FETs are used, the first FET 1 being short-circuitted between its gate and source and the second FET 2 being short- circuitted between tits drain and source which drain and source ar series connected to the source of the FET 1 and the FET 2 being further grounded at its source. Voltage VD is applied to the drain of the FET 1. The FET 1 operates in a saturated region because VD is sufficiently high, while the FET 2 operates in a nonlinear region because its drain and its source are the same potential. When threshold voltages of the FETs 1 and 2 are assumed to be both Vth, and K values are assumed to be and ak (a is a positive real number), VOUT =-Vth/[a+(a<2>+a)<0.5>] holds. Accordingly, knowledge of VOUT allows Vth to be estimated with ease.

Title: Beam irradiation device

IPC: G21K5/04
Filed: 1995-04-11
Abstract: PURPOSE: To reduce the space occupied by equipment and costs of it by forming a structure equipped with a particle beam generator and a sheet supplying means. CONSTITUTION: A sheet 7 is supplied to an irradiating zone at a constant speed by rollers 12a, 15a, 15b and 12b. As to the rollers 12a and 12b, one is irradiated with electron beams 6 from the front and the other from the rear. The beams 6 output from an electron beam generator 1 is long and narrow; as thick as or thicker than the interval between the rollers 12a and 12b and as wide as or wider than the width of the sheet 7. Most of the beams 6 penetrate the front and the rear of the sheet 7 and get to a reflector 16. The part of beams which have failed to get to the sheet 7 reach the reflector 16 directly. Then, they are reflected and get to the rear and the front of the sheet 7 again. Moreover, they become damping X rays, which get to the rear and the front of the sheet 7. The reflector 16 is cooled as necessity requires.  In this way, a single device 1 can continuously irradiate the front and the rear of the sheet 7 at a time and the irradiating efficiency improves significantly, so that the device can be downsized and the costs of its can be reduced.
