Abstract: PURPOSE:To make an electrode operate also as a heating body, and thereby to simplify the construction and to lower the cost, by a method wherein the electrode to serve as the heating body is formed of a conductive material in a required pattern on a substrate and a semiconductor whose conductivity is varied with the adsorption of gas is applied on said electrode. CONSTITUTION:A current is made to flow through lead wires 24 so that the whole of a gas detecting element is maintained at a temperature of 300 deg.C-500 deg.C. The electroconductivity of a gas detecting layer 23 is increased with the molecules of gas adsorbed on the surface thereof. The resistance value Rh of an electrode 22 and the specific resistance value of the gas detecting layer 23 are selected to be in an appropriate ratio between them. A current path is a composite of a path running through the part of the electrode 22 and a path running through the gas detecting layer 23 which is distributed in parallel in spaces formed by the electrode 22. While the resistance value Rh of the part of the electrode 22 is not varied virtually by the contact thereof with gas, the distributed resistance R's of the part of the gas detecting layer 23 is varied to a large extent by the contact with the gas, and is integrated into an apparent parallel resistance Rs. Thus, the device can be employed as a stable gas-detecting element.

Title: Stepping motor controller
Inventor: FURUKAWA AKITERU
IPC: H02P8/00
Filed: 1988-03-07
Abstract: PURPOSE:To drive a motor with a suitable torque even when the speed of the motor is varied by determining the current value on the basis of the rotating speed. CONSTITUTION:A value responsive to the pulse internal of the driving pulse of a motor is held in a latch circuit 14, and input to a D/A converter 15. The converter 15 outputs a preset voltage in response to the input value. When the driving pulse is short, i.e., when the speed of the motor is fast, it outputs a high reference voltage, and when the pulse is long, i.e., when the speed of the motor is slow, it outputs a low reference voltage. This output is used as the reference voltage of a comparator 9. That is, when the motor is desired to be accelerated, the reference voltage of the comparator 9 is raised, i.e., and the winding voltage is increased, while when the motor is desired to be decelerated, the reference voltage is reduced, and the winding current is decreased.

Title: Method for developing image having three-dimensional feeling
Inventor: KATAMOTO TSUTOMU
IPC: C01G49/06
Filed: 1989-03-03
Abstract: PURPOSE:To develop an image having a three-dimensional feeling by a method wherein a coating material formed by compounding a planar hematite particle of specific average diameter, thickness, and planar ratio in a coating material forming base is applied on the surface of a molded article, and a magnetic field is applied to the coating material in an undried state. CONSTITUTION:A coating material formed by compounding a planar hematite particle of 0.5-5.0mum average diameter, 50-500Angstrom thickness, and 50:1-500:1 planar ratio in a coating material forming base is applied on the surface of a molded article. When a magnetic field is applied to the coating material in an undried state, an image formed by controlling the strength and direction of a magnetic flux can be developed on the surface of the molded article, and the image developed part is seen as if it is recessed. The large color difference between a magnetic field applied part and the other part results in a remarkably good three-dimensional feeling. Because the planar hematite particle of 0.5-5.0mum average diameter, 50-500Angstrom  thickness, and 50:1-500:1 planar ratio is golden, it becomes a golden coating material having a metallic luster by being compounded in the coating material forming base. Therefore, a high-quality feeling and a massive feeling are further improved in addition to the forming of an image with a three-dimensional feeling.
