Title: Programmable controller
Inventor: DEKI JINTARO
IPC: G05B19/05
Filed: 1993-05-10
Abstract: PURPOSE:To facilitate the setting of a required and minimum communication parameter for setup of connection. CONSTITUTION:Upon the detection of application of power to a master station unit 2, a CPU 21 accesses an EEPROM 25 to read a communication parameter to discriminate whether or not the communication parameter is valid and sets up connection based on the communication parameter when the communication parameter is not in error. On the other hand, when the communication parameter read from the EEPROM 25 is in error or no communication parameter is stored because at first application of power after factory shipment, a default value communication parameter is transferred from a PROM 24 to the EEPROM 25 and the connection is set up based on the communication parameter.

Patent JP-H09293405-A (JP)
Title: Reflector, incandescent lamp and luminaire
Inventor: KAMATA HIROSHI
IPC: G02B5/28
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To secure excellent visible light reflectivity and infrared ray transmittance by forming a photocatalyst layer on a visible light reflection infrared ray transmitting film. SOLUTION: Out of light radiated from a tungsten halogen lamp 11 toward a rotary quadratic surface reflector 9 to be incident to a reflected face of the reflector 9, visible light is reflected on a visible light reflection infrared ray transmitting film 2. In contrast, most of the infrared ray is absorbed toward the reflector 9 (base member) through the film 2, and then, heat is radiated via the reflector base member 9. That is, the infrared ray is selectively transmitted and absorbed, so that the visible light, which does not include the infrared ray and is decreased in temperature, is reflected, thereby achieving light irradiation and illumination without any thermal effect.  Meanwhile, a photocatalyst layer 3, which never deteriorates the visible light reflecting and infrared ray transmitting effects, is formed on the film 2, so as to exhibit photocatalyst activity upon light radiation from the lamp 11. Consequently, it is possible to easily decompose and remove organic dusts or the like floating or being present in the surroundings and adhering the surface, thus preventing contamination.
Patent JP-S5631519-A (JP)
Title: Automatic tapping screw
Inventor: HARORUDO KEISU GAANEE
IPC: F16B25/00
Filed: 1980-08-08
Abstract: A drill screw for drilling through soft packing material such as timber into a steel purlin has a drill point (12), a threaded shank (11) and a head (13). The srew thread (14) is interrupted by longitudinally extending flutes (19) otherwise adapted to become at least partially filled by loose packing material generated by drilling so that the thread tends to ream out the packing material and prevent an effective threaded connection between packing material and drill srew. This allows the drill screw to advance at the normally required slow advance when the drill point engages the purlin.

Title: Current zero-point sensing device
Inventor: ISHIKAWA MASAYUKI
IPC: H01H9/56
Filed: 1988-05-06
Abstract: PURPOSE:To provide stable operation by allowing current to flow in a superconductor, and sensing the current zero point by the use of non-linearity transferring from the normal conductive to superconductive condition or vice versa according to current value. CONSTITUTION:In a system 12 the total current 7 or part thereof is sensed by a current transformer 13 and introduced to a superconductor 14. Because this superconductor 14 is in normal current condition with a large current value, the potential difference at the two ends is great. When the current value decreases to become below the critical value, the superconductive state is introduced, and the potential difference 23 nearly nullifies. This potential difference 23 is accordingly in the waveform close to rectangular waves, and passing it further through a differentiation circuit 17 and a rectifying element 18 generates current DC pulses. The current zero point sensing becomes possible through utilization of the non-linearity of this type superconductor 14. That is, the voltage effect of the superconductor 14 can be sensed and generation of current zero point be predicted from the potential difference 23, which accomplishes a current sensing device with stable operation.

Title: Production of thin film
Inventor: USHIKUBO TAKASHI
IPC: C23C14/54
Filed: 1983-06-20
Abstract: PURPOSE:To control freely the ZnO/SiO2 ratio of a sputtered film in the stage of forming the sputtered film consisting of ZnO and SiO2 on a base plate by regulating the negative biasing voltage to be impressed on the base plate. CONSTITUTION:A target 23 contg. ZnO and SiO2 and a base plate 24 are placed to face each other and Ar<+> plasma 22 is generated between both by a high frequency power source 21. ZnO and SiO2 are released from the target 23 by the sputtering effect generated when the plasma 22 collides against the target 23, by which a thin film mixed with ZnO and SiO2 is formed on the plate 34. The Ar<+> ion of the plasma 22 in this case is also made incident to the surface of the plate 24 by the negative biasing voltage impressed by a DC power source 26 to sputter again the thin film 25 on the surface of the plate 24. Since the value of ZnO/SiO2 of the film 25 can be freely adjusted by regulating the negative biasing voltage value to be impressed, the film 25 having different ZnO/SiO2 ratios is freely formed with one target.
