Title: Ethylene polymerization method and apparatus
Inventor: ADORIAN NITSUKO
IPC: C08F4/619
Filed: 1979-12-27
Abstract: A process and apparatus for widening the molecular distribution of ethylene polymers produced at high pressure and at high temperature by polymerizing ethylene at a pressure between 600 and 3,000 bars and at a temperature between 160 DEG  C. and 320 DEG  C., in two reactors operating in parallel. In the first reactor, the reaction takes place in the presence of less than 0.1% of hydrogen for the purpose of producing a polymer of high molecular weight. In the second reactor, the reaction takes place in the presence of 0.2 to 5% of hydrogen for the purpose of fabricating a polymer of low molecular weight. The effluents from these two reactors are expanded and then moved to a set of two separators interconnected so as to efficiently mix the polymers produced in the two reactors by recycling the least possible amount of hydrogen into the supply circuit of the first reactor in such manner that the proportion of hydrogen in the first reactor remains less than 0.1% in moles. Ethylene polymers are produced with a fluidity index between 0.1 and 2 and a polydispersity index larger than 8.

Title: Gas concentration sensor
Inventor: SASHITA TAKAO
IPC: G01N27/416
Filed: 1986-07-18
Abstract: PURPOSE:To detect an oxygen concn., etc. with simple constitution, by providing a pair of electrodes to one side of a solid electrolyte and oxygen diffusing means to one of the electrodes. CONSTITUTION:The electrodes 21, 22 are formed to one side of the solid electrolyte 1 and a holed cap 3 formed with a diffusion hole 30 is provided to the electrode 22. A heater 5 is energized to heat the electrolyte 1 and to improve the ion conductivity thereof and a voltage is impressed to the electrodes 22, 22 by a voltage source 6 to function the electrolyte 1 as an oxygen pump. The oxygen O2 is ionized to O<2-> by receiving electrons at the electrode 22. The ion O<2-> penetrates the electrolyte 1 and arrives at the electrode 21 where the ion is converted again to the oxygen O2. The oxygen is discharged to the external air. The external air contg. the oxygen O2 diffuses and flows into the cap 3 through the hole 30 to the extent of not exceeding the oxygen delivery power of the oxygen pump of the electrolyte 1 and the current corresponding to the oxygen partial pressure flows to the electrodes 21, 22. The oxygen concn. in the air is detected by measuring the current value with a current measuring means 7.

Title: Piezoelectric force sensor
Inventor: GERARUTO HOPUFU
IPC: G01L1/18
Filed: 1994-07-21
Abstract: PURPOSE: To surely detect the breakage of a plate by electrically contacting a piezoelectric force sensor with at least an electrode on one side via one or more conducting passages, which are provided on a piezoelectric plate, and breaking the conducting passage when the plate is broken. CONSTITUTION: The piezoelectric plate 1 consisting of two plate half parts 2, 3 is fixed to a carrying body 8 on its lower surface via a supporting body 7. An electrode 5 is installed in the entire surface of the lower surface of the plate 1, while a patterned electrode 4 is installed in the upper surface. The electrode 4 is brought electrically into contact with a connecting wire 6 fixed to a start area 12, while the area 12 is connected to the electrode 4 by means of a conducting passage 20. The electrode 5 is electrically connected with a conductive supporting body 7 by means of other conducting passage installed in the carrying body 8.  When the sensor is used as an acceleration sensor, since the acceleration in the direction perpendicular to the surface of the carrying body 8 is produced so that a moving area 11, which is not supported by the supporting body 7, moves, a mechanical load is applied to a bent wire 10. When the plate 1 is broken in an around the bent wire 10, the conducting passage 20 is broken. As a result, the capacity of the plate 1, which is measured via the conducting passage 20 varies. Thus, the breakage of the plate 1 can be detected.

Title: Semiconductor photodetector and its manufacture
Inventor: KUSAKABE ATSUHIKO
IPC: H01L31/0232
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a photodetector providing a high coupling efficiency, high internal quantum efficiency and high speed response. SOLUTION: A U-shaped waveguide structure formed on an InP substrate is composed of a first inclined absorption region A, waveguide type absorption region B and second inclined absorption region C. When a signal light enters a photodetecting face 12, it is first absorbed at the first region A, penetrating light is absorbed at the region B and still penetrating light enters and is absorbed at the second region C. It follows that the photoabsorption layer is made effectively thick as seen from the end face. This facilitates the coupling with optical films, etc., and provides a high quantum efficiency.
