Title: Test of thermal head
Inventor: KUROKI KENJI
IPC: H01C17/00
Filed: 1985-05-27
Abstract: PURPOSE:To obtain a resistance change curve with information much in a short time, by holding the number of pulse of an electric signal to be applied to a heat generating resistor at each power step and the power step to increase the power within a specified range. CONSTITUTION:An electrical signal for increasing the power at a fixed power step is applied to a heat generating resistor 25 intermittently in sequence at each power step and changes in the resistance of the heat generating resistor 25 from the initial resistance value thereof are measured at each step to perform a step stress test for a thermal head 24. Then, the number of pulse of the electrical signal applied at each power step is held within 1 - about 100 while the power step for increasing the power is held within the range of 1/100-1/10 of the printing power for each power step. The setting of such a test condition enables a resistance changes curve providing the rate of change in the resistance with respect to variations in the power in a short time while the resistance changes curve containing much necessary information can be obtained.

IPC: H01C10/36
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a rheostat which can increase voltage change width. SOLUTION: First to fourth resistors 61-64 and first to sixth conductors 65-70 are printed on a PC board 2 of a rheostat. The first to fourth resistors 61-64, the second to fourth conductors 66-68, a bend part 65b of the first conductor 65 and a bend part 69b of the fifth conductor 69 are printed on the same circle. A ring part 72 of the sixth conductor 70 is annular. A first sliding part of a sliding member slides along the ring part 72, and a second sliding part slides along a virtual circle formed by the first to fourth resistors 61-64. In each of the ranges in which an operation angle is 0-θ1, θ2-θ3, θ4-θ5, θ6-θ7 and θ8-θ9, a voltage ratio is constant. In each of the ranges, in which the operation angle is θ1-θ2, θ3-θ4, θ5-θ6 and θ7-θ8, the voltage ratio changes. Since the ranges where the voltage ratio becomes constant are arranged, the voltage change width can be increased in the ranges (especially in θ5-θ6), except for the ranges of a constant voltage ratio.

IPC: H02K7/116
Filed: 1984-06-04
Abstract: PURPOSE:To effectively shorten the direction of an output shaft by providing a disc-shaped electric coil and a field magnet. CONSTITUTION:When a current is flowed from a power source to an armature coil 10, a magnet 14 is rotatably driven at a main shaft 11 as a center in a servo motor, and its rotary force is transmitted through a gear 141 to the first to the third planetary gears 21 to 23.

Title: Power transmission on-off mechanism
Inventor: MURATA KIYOHITO
IPC: B60K17/35
Filed: 1988-05-11
Abstract: PURPOSE:To improve the torque transmission performance by mounting a means which operates in connection with the relative revolution of both propeller shaft members to generate the viscous resistance force, a means which operates on the thrust force to generate the frictional engaging force by which both members are joined with each other to transmit power, and a means which converts the viscous resistance force to the thrust force. CONSTITUTION:When relative revolution is generated between both propeller shafts 25 and 26, differential revolution is generated among an outer case 11, an inner case 12 and an operating plate 13 so that a viscous friction torque T is generated between the plate 13 and a primary cam member 14. The resistance force F at each ball 18 is T1R (the R standing for the radius of the orbital circle of the balls 18). The resistance force F is converted by a thrust converting means 10c to a thrust used to operate a frictional engagement generating means 10b. A cam member 14 pushes a cam member 17 by this thrust force to make frictional engagement of a clutch plate 15 with a clutch disk 16. As a result, both cases 11 and 12 are connected to enable torque transmission so that the power of the shaft 25 may be transmitted to the shaft 26.

Title: Manufacture of ultrasonic transducer
Inventor: IZUMI MAMORU
IPC: G01N29/28
Filed: 1981-07-23
Abstract: PURPOSE:To adjust the thickness of a matching layer by instantaneously measuring the thickness from the end thereof to the surface of a piezo-electric vibrator utilizing an eddy current type displacement meter. CONSTITUTION:As shown by A, in this ultrasonic transducer, a reference value is obtained, a) when an electrode of a piezo-electric vibrator 2 directly contacts a displacement sonsor 5 before the setting of a matching layer or b) when the layer is set at a fixed space with a supporting base 6. Then, as shown by B, after the formation of the matching layer, a measurement is made a) when the matching layer 1 directly contacts the displacement sensor 5 or b) when the layer is set at a space with the supporting base 6. The comparison of the measured value with the reference value enables an accurate measurement of the thickness of the matching layer. Thus, the use of an eddy current type displacement meter permits the measurement of the thickness of the matching layer simply by bringing the ultrasonic transducer with the matching layer thereby simplifying the measuring operation for the adjustment of the thickness of a lambda/4 matching layer.

Title: Active low pass filter
Inventor: HATA TOSHIO
IPC: H03H11/12
Filed: 1989-05-08
Abstract: PURPOSE:To reduce the deviation of a cut-off frequency from a design value and to reduce the number of parts by using the collector capacity itself of a transistor TR as a capacity constituting a filter circuit tc determine the cut-off frequency. CONSTITUTION:Since a collector capacity 5 is equivalently placed between the base of a TR 1 and the ground, the collector capacity 5 itself is used to determine the value of a resistance 2 so that a desired cut-off frequency is obtained. Thus, it is unnecessary to insert another capacitor between the base of the TR 1 and the ground, and the deviation of the cut-off frequency from the design value is reduced and the number of parts is reduced.
