Title: Gas concentration sensor
Inventor: ISHIKAWA HIDEKI
IPC: G01N29/02
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain a gas concentration sensor which can stably and highly accurately measure a gas concentration of a specific gas even when a gas to be measured has a high flow velocity. SOLUTION: A diameter of an outflow path 38 is made smaller than a diameter of an inflow path 37, and a bypass path 39 is set between the inflow path 37 and outflow path 38. As a result, not only a flow resistance of a gas flow is increased at the outflow path 38, but a gas flow inclined to flow to a measurement chamber 34 is branched to the bypass path 39. In other words, according to a gas concentration sensor 25, even when a flow velocity of a suction air in a piping where the gas concentration sensor 25 is arranged is high, an increase in flow velocity of the suction air in the measurement chamber 34 can be restricted sufficiently, whereby a modulation point of ultrasonic waves can be correctly detected. That is, a propagation time of ultrasonic waves can be correctly measured and therefore, a gas concentration can be highly accurately measured.

Title: Heating roll for fixing device
Inventor: UEHARA YASUHIRO
IPC: G03G15/20
Filed: 1981-03-20
Abstract: PURPOSE:To distribute a release agent uniformly over the entire surface of a heating roll and to prevent the generation of offset by forming the heat-resistant coating layer of the surface of said roll porous. CONSTITUTION:When the surface tension of the heat resistant coating layer (tetrafluoroethylene resin layer) 4 of a heating roll 1 is smaller slightly than the surface tension of a release agent (silicone oil) 7, the wetting of the oil to the roll surface is not sufficient and this produces the areas where no oil films exist partially, which can lead to offset. If the layer 4 is formed porous, the apparent surface area of the heating roll increases and the wetting to the release agent is improved. In addition, the release agent percolates into the pores and as a result, the release agent distributes uniformly over the entire surface of the heating roll thereby generating virtually no offset on the surface of the heating roll.

Abstract: PURPOSE:To prevent a separated brightness signal from being deteriorated by changing the band of a BPF to which the output of a comb filter is inputted in accordance with the state of the input signal and separating the brigtness signal based upon the output of the BPF. CONSTITUTION:A synthetic color TV signal inputted to a terminal 1 is inputted to an one line comb filter consisting of a one-horizontal scanning delay circuit 3 and an adder 4. A color signal is outputted from the adder 4 and supplied to plural parallel band variable BPFs. Although a narrow band BPF 7 is normally selected by a switch 8, a medium band BPF 6 and a wide band BPF 5 are successively selected in accordance with the increment of the color signal level. When a color signal component level in the output of the BPF 7 is small, dot interference is low and the output is mixed with the output of a uniform pressure circuit 2, so that oblique resolution is not deteriorated. Since the BPFs 6, 7 are successively selected in accordance with the increment of the output level of the BPF 7, the generation of dot interference can be prevented.
