Title: Fault judging method for throttle position sensor
Inventor: OMORI SHOGO
IPC: F02D45/00
Filed: 1987-02-19
Abstract: PURPOSE:To make an accurate judgement by judging that a throttle valve full-close position detection sensor is defective if a full-close signal is outputted from the throttle valve full-close position sensor and detected value of volumetric intake quantity being fed to an engine is higher than a predetermined value. CONSTITUTION:An air cleaner 13 is fixed to an intake tube 12 coupled to an engine 10, and a Karman voltex type air flow sensor 14 for detecting Karman vortex generation frequency corresponding to volumetric intake quantity being sucked to engine is arranged. A throttle valve 15 is arranged in the intake tube 12, and a throttle valve full-close position detecting sensor 30 is coupled to the throttle valve 15. Respective sensors 14, 30 are connected to a control unit 20. Consequently, when a full-close signal is outputted from the throttle valve full-close position detection sensor 30 and the detected volumetric air flow is higher than a predetermined value, it is judged that the throttle valve full-close position detection sensor 30 is defective.

Title: Piezoelectric crystal film of zinc oxide
Inventor: YOSHINO YUKIO
IPC: C01G9/02
Filed: 1983-03-02
Abstract: PURPOSE:To prevent the generation of internal stress in a piezoelectric film and to prevent the generation of cracks, crazings, warpage, etc. of substrate, by using Mg as a component of a zinc oxide piezoelectric crystal film formed on a substrate. CONSTITUTION:A substrate made of glass, ceramic, etc. is placed on the anode of a high-frequency sputtering apparatus, and a zinc oxide ceramic target containing 0.05-5 atomic % of Mg is placed on the cathode. The vacuum chamber is evacuated, a gas composed of oxygen and argon is introduced into the vacuum chamber, and high-frquency potential is applied to the electrodes to form a piezoelectric crystal film containing 0.05-5 atomic % of Mg on the substrate. Since the added Mg reacts with excess oxygen atoms in the obtained piezoelectric crystal film to prevent the intrusion of oxygen in the lattice defect or between lattices of the zinc oxide, there is no generation of internal stress, and accordingly, the cracking, etc. of the substrate can be prevented.

Title: Magnetic ink recording apparatus
Inventor: YAMAZAKI FUMIO
IPC: B41J2/06
Filed: 1983-03-02
Abstract: PURPOSE:To prevent the generation of the noise flight of magnetic ink by reducing the projection thereof, by a method wherein the diameter of the leading end surface of a recording needle in the direction at right angles to the recording needle arranging direction is made larger than that in the arranging direction and brought to 60% or more on the basis of the diameter of the recording needle. CONSTITUTION:A recording electrode 10 to which voltage corresponding to an image signal is applied between the gap with an opposed electrode 15 from a voltage control means 16 is formed in such relation that D2>D1 and D2>=0.6D0 are formed when the diameter of the leading end thereof from which an urethane coating is peeled off is set to D0, the diameter thereof in a recording needle arranging direction to D1 and the diameter thereof in the direction at right angles to the arranging direction to D2. Therefore, the magnetic ink 10 supplied to a protruded magnet 12 forms a projection part on the recording electrode 10 but the leading end radius R2 thereof becomes small as compared with a coventional one and the flight selectivity is enhanced to reduce noise flight. In addition, the ink adhering thickness at the leading end is doubled and discharge is hardly generated in the same flight voltage.

Abstract: PURPOSE: To eliminate the catalyst removal step and to produe a flame-retarding cyclic acetal polymer excellent in heat stability, by polymerizing or copolymerizing a cyclic acetal in the presence of a halogen-containing cyclic trivalent phosphorus compound.  
     CONSTITUTION: A cyclic acetal such as trioxane or tetraoxane is polymerized or copolymerized in the presence of a catalyst which is a halogen-containing cyclic trivalent phosphorus compound. Then, the polymerization porceeds mildly and the catalyst is introduced into the polymer chains. Accordingly, the catalyst removal step after the reaction can be eliminated. Moreover, phosphorus is introduced into the polymer chains, so that the resulting polymer shows excellent heat stability and flame retardency. Furthermore, it becomes possible to modify the polymer with a halogen. As the above copolymerizable components, there are used, for example, cyclic ethers such as ethylene oxide, popylene oxide and 1,3- dioxolane.

Abstract: PURPOSE:To release the difference in a temperature between the inside of this device and the surface of a drum and to keep a surface temperature constant by providing a heater and a sensor controlling the heater inside an image carrier and always setting the heater at an arbitrary temperature. CONSTITUTION:The heater 18 passes through the inside of an image carrier drum 1 and further, the temperature of the heater 18 is controlled by the sensor 19, so that the difference between the temperature inside the device and the surface temperature of the image carrier drum 1 does not occur. Then, the sensor 19 is attached to a sensor supporting frame body 20, and the heater 18 is formed so as to pass through a drum supporting shaft 7 as the center of the drum supporting frame body 17. Thus, the occurrence of the dew condensation of the surface of the image carrier drum, which can be observed just after the device is operated at the time of a low-temperature, can be suppressed. The performance of an OPC drum used as the image carrier at present is influenced by temperature characteristics, but the surface temperature of the OPC drum can be kept constant, so that, characteristics at a constant level are guaranteed.
