Title: Overvoltage-input protective circuit for input of resistance thermometer element
Inventor: SAITO HITOSHI
IPC: G01K7/20
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain an overvoltage-input protective circuit which prevents an internal circuit from being damaged when an overvoltage is applied such as when a power supply or the like is connected mistakenly to an input terminal by a method wherein a bipolar transistor is inserted across the gate and the source of a MOS transistor and the base is connected, via a resistor, to a ground or to a stable potential part inside the internal circuit. SOLUTION: In an ordinary operation, the measured current of a resistance thermometer element (RTD) 1 is turned on/off by a MOS transistor Q1 through a resistor R1 so as to flow to the RTD 1. A current value can be known by measuring a voltage across both ends of the resistor R1, and the resistance value of the RTD 1 can be found on the basis of it. A part across the emitter and the base of a bipolar transistor Q2 is reverse-biased, the transistor Q2 is turned off, and the operation of the protective circuit is not affected. When a positive overvoltage is applied to an input, the parasitic diode of the transistor Q1 is set to continuity, and an input voltage is shouldered mostly by the resistor R1. A positive overvoltage is applied to the emitter of the transistor Q2, and a part across the emitter and the base of the transistor Q2 is reverse-biased.

Title: Film laminate
Inventor: NOSE KATSUHIKO
IPC: B32B27/30
Filed: 1989-11-15
Abstract: PURPOSE:To obtain a laminated film having both surfaces excellent in durability without damaging the physical properties of a base film by a method wherein the surfaces of the A- and C-layers of a thermoplastic resin laminated film composed of at least A-, B- and C-layers or A-, B- and A-layers are subjected to discharge treatment in the presence of fluorine gas and satisfy a specific condition. CONSTITUTION:For example, a resin wherein the polarity force component in the total surface energy is 10erg/cm<2> or less is laminated to both surfaces of a polyester film and the surfaces of A- and C-layers are subjected to discharge treatment in the presence of fluorine gas. At this time, by allowing the surfaces of the A- and C-layers to satisfy a condition represented by formula I, the total surface energy of the surface of each of both layers is lowered to 20erg/cm<2> or less. By this method, a laminated film consisting of the fluorinated A- and C-layers having high hydrophobicity and a B-layer composed of polyester having good adhesiveness is obtained. As mentioned above, by providing specific surface layers to the surface of a thermoplastic resin film and subsequently applying discharge treatment thereto in the presence of fluorine gas, a resin film having highly fluorinated surfaces can be obtained within an extremely short time.

Title: Vapor growth system
Inventor: ITO HIROMI
IPC: H01L21/205
Filed: 1986-12-12
Abstract: PURPOSE:To achieve the contamination-free good epitaxial growth by a method wherein a blade is installed at a rotating part of a susceptor and the rotating part is turned by a gas sprayed on the blade with a view to preventing that a fine particle is produced due to wear and tear. CONSTITUTION:A rotating part 2R of a susceptor is placed on a support base 2B; the rotating part 2R is turned by supplying an ordinary carrier gas from gas-supply pipes 5 and a gas-guide hole 6. The turning direction and the number of revolutions can be controlled easily by selecting the amount of flowing gas from the two gas-supply pipes 5. In addition, a bouyant force acts on the rotating part 2R of the susceptor by the flowing gas and the rotating part 2R floats up slightly from the support base 2B; the contact between both parts is almost lost. By this method, the production of a fine particle due to wear and tear is prevented, and the contamination-free good epitaxial growth is achieved.

Abstract: PROBLEM TO BE SOLVED: To change a strobe light irradiation angle over a wide range including a telescopic side without any increase in a size of a device and prevent illumination unevenness around a photographed image plane. SOLUTION: A strobe light emitting unit 10 is constructed of a strobe discharge tube 20, a reflector 21, and a Fresnel lens 22 and a guest-host type liquid crystal plate 23 which are installed in the rear and front parts of a spacer box 24 apart from each other at the predetermined interval. On the basis of the position of a variator 7b, impression voltage to the liquid crystal plate 23 is controlled, and a light diffusion ratio of the liquid crystal plate 23 is regulated to the value complying with a focal length of a zoom lens 7. The strobe light beams emitted from the strobe discharge tube 20 are condensed in the Fresnel lens 22 and turned into the substantially parallel beams so as to be incident on the liquid crystal plate 23 vertically.  The emission angles of the strobe light in the central part and in the circumferential part of the liquid crystal plate 23 are equalized to each other substantially, so that illumination unevenness is hardly generated in the periphery of a photographed image. On the telescope side of the zoom lens 7, a light diffusion ratio of the liquid crystal plate 23 is reduced and light condensing effect by means of the Fresnel lens 22 is increased relatively, so that a reaching distance of strobe light can be increased by means of a small size strobe device 9.

IPC: C04B35/628
Filed: 1987-11-26
Abstract: PURPOSE:To prevent the generation of a depressed ball and to excellently granulate ceramic powder by spray-drying the raw ceramic powder with the use of the nonaqueous solvent slurry contg. a binder and polyethylene glycol monooleate. CONSTITUTION:The raw ceramic powder is spray-dried with the use of a nonaqueous solvent, and granulated. In this method, the powder is spray-dried with the use of the nonaqueous solvent slurry contg. a nonaqueous solvent, a binder, and polyethylene glycol monooleate. The amt. of the polyethylene glycol monooleate is preferably controlled to 0.3-5pts.wt., based on 100pts.wt. raw ceramic powder. At <0.3pts.wt., the effect is lost, and a further effect cannot be expected at >5pts.wt. The HLB of the polyethylene glycol monooleate is most preferably controlled to <=13. At >13 HLB, the hydrophilicity is increased, and the effect when added to the nonaqueous solvent is reduced.

IPC: G08G1/042
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To accurately sense a vehicle regardless of the inductance and sensitivity of a loop coil. SOLUTION: A self-excited oscillation circuit 102 oscillates frequency with an inductance L which changes with the approach of a vehicle, and a programmable counter 105 divides the frequency to obtain a gate signal. The output voltage of the self-excited oscillation circuit 102 is digitized by an A/D converter 103. A reference clock counter 107 counts a reference clock with a constant period and stops counting by the gate signal. A control part 110 judges the detection of a loop coil from detection judgment information read from a judgment table and the count value of the reference clock according to the peak value of the output of the A/D converter 110 when the counting stops due to the gate signal and outputs 'sensing' when the 'sense' continues for more than specified.  Also, a preset value is calculated from the count value of the reference clock and is written to the programmable counter 105 at a certain period. Then, sensing state, count value, and failure state are communicated.
