Title: Pulse scan radar sensor device
Inventor: BOEHMKE SCOTT
IPC: E02F9/20
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To make a high speed three-dimensional scan radar sensor system give a range map in an operation environment where it is disturbed by dust, fog and rain. SOLUTION: The sensor system 20 radiates a sensor beam formed by high frequency energy pulses of a short duration time. The direction of the sensor beam is controlled by using a scan mechanism provided with a high speed revolution reflector. It includes a timing system 24 for determining elapsing time between a radiation signal and reception signal. The time difference indicates the distance to the target which reflected energy. The signal returned from an antenna is controlled and transmitted to a constant fraction discriminator(CFD) for surely detecting the time when the reflection signal is received. A high accuracy timer starts at a certain time for energy release and stops at a time the CFD detected a trigger. This timing system 24 produces an analog voltage which is proportional to the down range distance to the target.

Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To suppress the error of an output level owing to the temp. characteristic of a wave detector by attenuating the output signal of a power synthesizer by means of a temp. variable attenuator having a temp. characteristic for compensating the temp. characteristic of the wave detector. SOLUTION: The output signal of the power synthesizer 13 is attenuated by the temp. variable attenuator 15 having a temp. characteristic for compensating the temp. characteristic of the wave detector 16. A comparator 18 compares the wave detection signal of the wave detector 16 for detecting the output signal of the attenuator 15 with a reference signal which is outputted from a reference signal generator 17 and corresponds to the output frequency of a variable frequency generator 4 and a variable attenuator driver 19 outputs a control signal for eliminating the difference of the comparator 18 to the variable attenuator 2. Thus, the variable attenuator 2 attenuates the output level of a fixed frequency oscillator 1 to output the signal with the desired output level from an output terminal 14.  The power synthesizer 13 is constituted without using nonlinear parts so that the level of unwanted wave which becomes high by the use of nonlinear parts is suppressed to be equal to below a desired level.

Title: Drive controller for ultrasonic motor
Inventor: SUKAI NAOKI
IPC: H02N2/00
Filed: 1990-12-10
Abstract: PURPOSE:To control an ultrasonic motor stably at a constant speed with substantially constant speed variation rate by performing switching control of the frequency variation rate of an AC signal according to the temperature of the ultrasonic motor detected through a temperature sensor at the time of constant speed control. CONSTITUTION:Upon decision that the rotational speed is higher than a target speed, voltage data is subjected to subtractive update and the frequency of an AC signal increases. Upon decision that the rotational speed is lower than the target speed, the voltage data is subjected to additive update thus decreasing the frequency of the AC signal. A decision is made whether the frequency has varied and if the time has expired, a decision is made whether the temperature data has varied. When the temperature data has varied, switching is made to a coefficient corresponding to that temperature data and a timer is actuated again. Consequently, when the temperature rises during constant speed control to cause variation of the temperature data, frequency variation rate of the AC signal with respect to an ultrasonic motor increases and the ultrasonic motor is controlled stably at a constant speed with substantially constant variation rate regardless of temperature variation.

Filed: 1990-12-07
Abstract: PURPOSE:To obtain high sealing properties of a seal ring for a valve rod or the like by spirally winding a tape material of high strength to form each cord-shaped body, and pressing and joining each cord-shaped body to an expanded graphite body which is flatly deformed for preliminary molding. CONSTITUTION:A seal ring 1 comprises cord-shaped bodies 4,4 integrally pressed and joined to both end faces of an expanded graphite body 2 preliminarily molded into the shape of a ring, each of the cord-shaped bodies 4, 4 being made by a stainless tape material spirally wound. The seal ring 1 can thus be machined into such form and size as corresponding to those of a sealed portion and the machining is so easy that the seal ring is best suited for manufacturing small-diameter components, and also the amount by which the cord- shaped bodies 4 are combined together is small so lowering of sealing properties is small and it is possible to select material suitable for various purposes. The cord-shaped bodies 4 are deformed with changes in the form of the expanded graphite body 2 during clamping and the sealed portion is stuck to each of the cord-shaped bodies 4 on a plane, thus preventing the expanded graphite from sticking out and also obtaining stable sealing properties even with a single seal ring body.
