Title: Liquid level detecting photosensor
Inventor: FUKAYA NAOKI
IPC: G01F23/292
Filed: 1987-01-12
Abstract: PURPOSE:To obtain a long life and to accurately detect a liquid level by converting variation in liquid level into magnetic field variation and detecting the magnetic field variation optically by a magneto-optical element. CONSTITUTION:When the liquid level is low, a permanent magnet 11 and the magneto-optical element 9 are at a distance from each other. Consequently, the element 9 is not applied with a magnetic field from the magnet 11 and the plane of polarization does not rotate. In this state, light 2 from a light source is not detected by photodetector 7. When the liquid level rises, the magnet 11 rises by the buoyance of a float 12 and the magnet 11 and element 9 come close to each other. Consequently, the element 9 is affected by the magnetic field from the magnet 11 and the plane of polarization rotates. Then, the plane of polarization of light which is emitted by an optical fiber 8 and passes through the element 9 is turned to be detected by the photodetector 7.

Abstract: PURPOSE:To calculate the correct cylindrical degree of even a deformed cylindrical work by obtaining the central point by the minimum area method where the difference of the radii of a first and second circles becomes minimum when the optimum reference point is set at the true center. CONSTITUTION:Points P1, P2, P3... where the distance from a reference point O passing the rotary shaft to respective peripheries of the measuring cross section is maximum, and points V1, V2, V3... where the distance from the reference point O to the respective peripheries becomes minimum are obtained for all the degrees. Points of the maximum distance and minimum distance when the reference point O is moved are selected from the above obtained maximum points and minimum points. When two circles respectively centering at the selected points are drawn, a point C where the difference of the radii of the first and second circles becomes minimum is obtained according to the minimum area method. A first circle C7 having the radius of the maximum distance to the periphery of each cross section, and a second circle C8 having the radius of the minimum distance to the periphery of each cross section are drawn by using the point C as the center. The difference of the radii indicates the cylindrical degree.

Title: Inverter circuit
Inventor: OKAMOTO FUTOSHI
IPC: H02M7/5387
Filed: 1982-01-15
Abstract: PURPOSE:To reduce the power loss of a starting resistor in an inverter circuit by inserting a switch element which conducts by detecting the terminal voltage of a smoothing condenser between the smoothing condenser and a control circuit. CONSTITUTION:When the voltage of a smoothing condenser C3 rises to cause a switch element S to conduct, a control circuit A starts operating, an inverter Q also starts operating, and produces a high frequency voltage output, and power is supplied through a transformer T1 and a rectifier B. Since the starting resistor R1 having high resistance value can be used in this case, its power loss is small, with the result that it is not necessary to isolate the resistor R1 via the switch element as the conventional one and a complicated control circuit therefor can be accordingly eliminated.

Abstract: PURPOSE:To decrease the error occurrence rate of correction, etc., by voice input by completing the registration of one instruction word and registering only the voice of a specific speaker when the same voice signal is voiced twice continuously at the time of registering the voice signal. CONSTITUTION:A voice signal storage means 52 converts a voice signal inputted to a microphone into a digital signal and stores it in word areas of a register and a storage element, and outputs the address signal of the word area. A 1st register 28 stores the address of the word area where the voice signal is registered. A 2nd register 30 stores the registration address of the word area where the same signal as the input voice signal is registered. A coincidence detecting means 32 outputs a coincidence signal when the contents of the 1st register 28 and the 2nd register 30 become equal to each other. A registration address specifying means 34 outputs the address specification signal of the word area, and receives the coincidence signal from the means 32 to update the registration address of the word area. When the voice signal is registered, the registration of the instruction word is not completed unless the same voice signal is voiced twice successively, and only the voicing of the specific speaker is registered in the word area.

IPC: F02B75/02
Filed: 1982-01-20
Abstract: PURPOSE:To improve a primary compression ratio by a variation of volume resulting from reciprocating motion of a plunger, by providing the plunger on one side of a crankcase. CONSTITUTION:When a piston 7 rises, the volume of a crankcase 1 becomes larger than a normal volume of the crankcase 1 by risen volume of the piston 7. A cam 15 pushing up a plunger 12 is apt to apart gradually causing expansion of a plunger chamber 11. The pressure becomes more negative by an extent of the volume expansion of the plunger chamber 11 and gas is absorbed into the  crankcase excessively. When the piston 7 descends, the volume of the crankcase 1 becomes smaller by the descended volume of the piston 7 causing contraction  of the volume of the plunger chamber 11.

Filed: 1990-01-16
Abstract: PURPOSE:To improve the quality of characters by preparing a table for indicating the thickness of a horizontal/vertical line corresponding to the size of a character and setting up the optimum line width corresponding to the size of a character to be generated. CONSTITUTION:The character generator 1 is provided with the table for indicating the thickness of a horizontal/vertical line corresponding to the size of a specified character, and at the time of executing affine transformation of a horizontal or vertical line detected from outline coordinate data, the thickness of the detected line is transformed into the thickness corresponding to the table indicating the thickness. The table for indicating the thickness is stored in a character pattern memory 6. Namely, the coordinate value of one line out of lines constituting the detected horizontal/vertical line is directly transformed and the coordinate value of the other line is set up so that the thickness obtained from the coordinate-transformed coordinate value of one line coincides with the value indicated by the table for indicating the thickness. Consequently, the dispersion of thickness can be removed and the characters of high quality can be generated.
