Inventor: TANAKA KUNIO
IPC: H05B3/10
Filed: 1990-11-26
Abstract: PURPOSE:To secure flexibility, uniformity of heating and a set watt density for a cylindrical heating element by using flexible heating thread which contains discontinuous fiber of stainless steel at one portion of thread to be supplied to a bobbin and making adjustment of the watt density within the range of 0.01-2.0w/cm<2>. CONSTITUTION:A cylindrical heating element is braided by use of a flexible heating thread 23 in a part of a thread 21 supplied to a right-turning bobbin and in a part of a thread 22 supplied to a left turning bobbin. Moreover, the cylindrical heating element is provided as one whose watt density is 0.01-2.0w/cm<2>. It is therefore unnecessary to wind a resistance wire around a pipe when it is heated and kept warm, and the cylindrical heating element is operative when a watt density is within the range of 0.01-2.0w/cm<2>, so that it is possible to generate heat within the range from 25 to 300 deg.C under the atmosphere of ordinary temperature. It is thereby possible to secure flexibility and keep heating and warmness at a fixed watt density and at such a temperature as desired.

Filed: 1992-11-27
Abstract: PURPOSE:To allow highly accurate motor control through a simple constitution at a low cost by calculating the difference between a position command value of a recording pen calculated depending on an input signal and an actually detected position of the recording pen. CONSTITUTION:A single chip CPU 1 performs nonlinear PID operation based on the difference between a pen position command data received from a main CPU and a pen position data. When the absolute value of the difference is larger than a predetermined value, forward/reverse ON/OFF control is performed in order to rotate a DC brushless motor 4 at a constant speed. In a region where the absolute value of the difference is smaller than the predetermined value, analog proportional control + integration control + dead band control is performed in order to control the DC brushless motor 4 delicately. Since inertia of the DC brushless motor 4 and the load thereof must be taken into account, brake is applied using differentiation control when the difference is decreased to an appropriate value.

Abstract: PURPOSE:To simplify a jack-up work by applying the constitution wherein it is judged that a vehicle is in a jack-up state when height is not reduced, even if a control valve for height reduction is open at the time of a vehicle stop, the height is saved and height adjustment is interrupted, and the height adjustment re-starts when the height begins to be reduced. CONSTITUTION:A control part 48 reads detected height from each of height sensors 50-1 to 50-4, and a detected vehicle speed from a vehicle speed sensor, and judges whether a vehicle is in a stop condition on the basis of the detected vehicle speed. Also, when height does not come down, regardless of height reduction control valves 46-1 top 46-4 open in one of suspension devices 4-1 to 4-4, the control part 48 judges that a vehicle is in a jack-up state, interrupts height adjustment and saves the height at the level. When the height begins to drop to or below the saved level, a jack-up process is judged to be complete and the height adjustment re-starts. According to the aforesaid construction, a jack-up work becomes easy.

IPC: G01F23/28
Filed: 1990-11-21
Abstract: PURPOSE:To make it possible to detect the interface level of a medium to be detected in a container and to detect the presence or absence of the level by detecting the change in input signal of a transmitted wave in a wave receiver based on the leakage of an ultrasonic wave into the medium to be detected from the wall surface of an ultrasonic-wave propagating member in contact with the medium to be measured. CONSTITUTION:When a liquid surface is high as shown by a solid line (a), leaking liquid (transmitted wave) l1 is substantially close to almost 0, and l2 and l3 are largely leaking. The transmitted wave from a wave transmitter 11 is weakened and inputted into a wave receiver 12. On the contrary, when the liquid surface is low as shown by a broken line (b), the substantial leaking liquid is only l3. The signal to the wave receiver 12 becomes strong. Therefore, the level of the liquid surface can be measured based on the strength of the signal.

Title: Manufacture of thick film thermal head
Inventor: SAKO TERUHISA
IPC: B41J2/335
Filed: 1990-11-22
Abstract: PURPOSE:To prevent the generation of electrochemical corrosion by baking a glass coating layer at temp. lower than the softening point of glass at the time of baking. CONSTITUTION:An overcoat glass layer 6 is formed using glass whose softening point is higher than baking temp. to cover electrode pattern conductors 3,4 and a resistor layer 5 and baked. That is, since the baking temp. is set so as to be lower than the softening point of glass, air bubbles in glass do not grow at the time of baking. As a result, no cavity is formed in the overcoat glass layer 6 and, therefore, no moisture or chlorine reaches the electrode pattern conductors 3, 4 from the outside. By this method, electrochemical corrosion can be prevented.
