Title: Resin laminated material in continuous form and manufacture thereof
Inventor: MABUCHI YUKIO
IPC: B32B27/06
Filed: 1989-06-19
Abstract: PURPOSE:To obtain a multipurpose sheet by a method wherein three-dimensional resin layer, which are printed on both sides of base material made of air-permeable sheet-like material in continuous form leaving space between patterns and arranged at the same position with respect to the base material, are provided. CONSTITUTION:Resin fluid is forced out of a rotary screen 104 so as to form resin fluid layer with the predetermined pattern on the top surface of the upper running band 103 of an endless belt 101. The resin fluid layer is passed through a heating section 110 by means of the running of the upper running band 103 so as to be half-molten. Next, the resin layer under half-molten state is adhered onto the under surface of non-woven fabric 107, which is continuously fed from a roll 106 onto the endless belt 101. Further, resin fluid is formed from a rotary screen 105 onto the top surface of the non-woven fabric 107 so as to adhere resin layer under half-molten state onto the under surface of the non-woven fabric 107. Furthermore, resin fluid is forced out of a rotary screen 104 onto the top surface of the non-woven fabric 107 so as to form resin fluid layer with the pattern, which is same as the pattern of the rotary screen 104, on the top surface of the non-woven fabric 107. The resin fluid layer is dried and solidified by being with a heating section 111 so as to be formed on the top surface of the non-woven fabric 107 as the resin layer with the predetermined pattern. Thus, resin layer can be printed continuously on both the sides of a sheet-like base material.

Title: Instrument for measuring mixing ratio of ice, snow, and water
Inventor: INOUE WAHEI
IPC: F24F5/00
Filed: 1992-05-25
Abstract: PURPOSE:To highly accurately measure the proportion of ice and snow in cooling water by measuring the conductivity of the cooling water transported through a force- transporting pipe by making an AC current to flow to a main measuring pipe connected in the middle of the pipe. CONSTITUTION:When the proportion of ice and snow in cooling water is measured by, for example, non-contacting electrodeless induction, a main annular insulating measuring pipe 4 connected to a force-transporting pipe 3 of the cooling water is surrounded with an annular excitation iron core 6 wound with an exciting winding 8 and annular current detecting iron core 7 wound with a current detecting winding 9. Accordingly, the cooling water flowing through the tube 4 flows through an annular closed pipe against the cores 6 and 7 and forms a kind of single winding just as an induced current passage. When an AC frequency power source 10 excites the winding 8, an AC current flows through the pipe 4 and an induced voltage is generated across the winding 9. Based on this voltage, a conductivity measuring means 12 indicate the detected current corresponding to the AC current flowing through the cooling water. Since the indicated current value corresponds to the amounts of the ice and snow contained in the cooling water flowing through the pipe 4, the proportion of ice and snow in the cooling water can be found.

Title: Displacement measuring apparatus
Inventor: INAGAKI TATSUHIKO
IPC: G01B11/14
Filed: 1990-06-13
Abstract: PURPOSE:To measure a fine displacement regardless of material of an object to be measured by arranging a photoelectric conversion means to measure intensity of a reflected light after a measuring light is reflected on a measuring surface and an arithmetic means to calculate a displacement value based on an output signal of the photoelectric conversion means. CONSTITUTION:An object 1 to be measured (film 5 for measurement) is set to be separate sufficiently from a measuring surface 11a, that is, a condition that a distance (x) is large sufficiently as compared with a wavelength lambda to cause a total reflection. Under such a condition, based on output signals Ea0 and Er0 of photoelectric conversion units 15a and 15r, Ea0/Er0 is calculated by an arithmetic means 30 and the results are stored into a device 30 as maximum relative quantity Imax of light. Then, the distance (x) is reduced so that the total reflection breaks, namely, a condition that the signal Ea is attenuated remarkable as compared with the signal Ea0 and a relative quantity of light I=Ea/Er is calculated from outputs Ea and Er at an optional moment and the results are divided by the quantity of light Imax to determine a reflection factor R of the measuring surface 11a. Then, the reflection factor R is substituted into a formula of a characteristic curve in the device 30 to calculate the distance (x) between the measuring surface 11a and the film 5. Thus, a displacement of the object 11 to be measured is determined from a change in the distance to be displayed.

Title: Synchronous motor
Inventor: NASHIKI MASAYUKI
IPC: H02K19/10
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce torque ripples by a simple construction by making the pole center angles formed in a rotor unequal, and providing center angles corrected in the peripheral direction for the uniform pole center angle of the stator. SOLUTION: The magnetically insulating parts 4 of a motor are so arranged that a real d-axis 21 may be shifted from an imaginary d-axis 6' being the original pole center by a shift angle θs 22, and this shift angle θs 22 is an angle for correcting the equal central angle θt of poles formed on the stator and has been confirmed experimentally. And when the number of poles P equals four, and the number of slots of the stator Ns equals twelve, and m=2, a fundamental central angle θt becomes 90 degrees, and a correction angle θs becomes 15 degrees, and the pole central angles θr become 105 and 75 degrees. This is a correction angle for aiming the reduction of a ripple component called a slot ripple mainly by the teeth of the stator 1.  As the result, torque ripples are canceled by each rotor pole pair mutually and reduced, and a synchronous motor having good controllability is obtained.

Filed: 1993-06-28
Abstract: PURPOSE:To suppress the waveform distortion of a signal by absorbing fluctuation caused by the number of attaching/detaching circuits to be mounted or difference in the combination of mounting positions in the characteristic impedance of a transmission line at the transmission line where a lot of attachable/ detachable circuits are connected. CONSTITUTION:A signal inputted from a terminal 1 is inputted to attachable/ detachable circuits 501-50n and on the other hand, that signal is passed through an analog switch 301 and terminated at any one of terminating resistors R1-R3. Since the characteristic impedance of the transmission line is fluctuated by the difference in the number of mounted attachable/detachable circuits 501-50n or the combination of mounting positions, the waveform distortion is generated and malfunction occurs inside the attachable/detachable circuits when matching with the terminating resistors can not be provided. At such a time, difference is generated in the counted results of high-speed counters 101 and 102 counting the number of pulses of the signal, the terminating resistors are chanted by controlling the analog switch 301 based on the compared result, and the optimum terminating resistor can be selected.
