Title: Ophthalmic digital ultrasonic measuring device
Inventor: DEIBUITSUDO UOREISU
IPC: A61B3/10
Filed: 1986-09-26
Abstract: Disclosed is a digital ultrasonic instrument for measuring the corneal thickness (often referred to as a pachymeter) and for measuring the axial length of the eye (often referred to as a biometric ruler). A number representing corneal thickness or axial length is displayed digitally on a liquid crystal display. The pachymeter incorporates a 20 MHz solid phase piezoelectric transducer, a microprocessor, a gate array, a hybrid analog receiver circuit, a liquid crystal display and four batteries. When axial length is measured, the instrument operates as a biometric ruler, a 10 MHz transducer is used and the software in the microprocessor is modified. Ultrasonic echoes generated by the transducer and various interfaces in the eye are sampled at the rate of 40 MHz which results in equal or greater sensitivity, resolution and accuracy as compared to other pachymeters and biometric rulers currently available. The 40 MHz sample rate is accomplished by use of a grey code counter and a binary counter, each of which is sampled twice after an ultrasonic echo is detected. The two grey code samples are compared to determine a valid sample period. A counter value obtained during a valid sample period is recorded in a shift register and compared to subsequent counter values corresponding to subsequent ultrasonic echoes. The apparatus for correlating ultrasonic echoes with particular counter values assures that the counter will be sampled at a point in time when the counter is stable as opposed to being in a state of transition. The apparatus allows for a counter accuracy of 25 ns.

IPC: H02P7/29
Filed: 1984-10-31
Abstract: PURPOSE:To always obtain a desired rotating speed by regulating the duty of a rotating direction designation signal in accordance with the detected output of the rotating speed of a motor. CONSTITUTION:A signal generator 221 generates a pulse signal having the period of (m) times of a ripple period of a motor torque. This pulse signal is pulse-width-modulated by a pulse width modulator 222, and applied as a rotating direction designation signal to a motor 21. The modulation factor of the modulator 222 is controlled in accordance with the detected output of a speed detector 26 for detecting the rotating speed of the motor 21. In other words, the pulse width of the input pulse signal and hence the duty of the input pulse signal is altered in accordance with the rotating speed error signal to follow the rotating speed of the motor 21 to the predetermined speed.

Title: Land mobile radiotelephone equipment
Inventor: HAGIMOTO NOBUO
IPC: H04W76/02
Filed: 1990-08-31
Abstract: PURPOSE:To eliminate a need to operate switches of a handset even at the time of telephone incoming or ringing-off by providing external switches for incoming and ringing-off in a place of a car room other than the handset. CONSTITUTION:When an external switch 1 for incoming is operated for the purpose of setting the hand free mode at the time of sounding of the ringing tone due to telephone incoming, a switch detector 3 detects this operation, and a switch function assigning circuit 4 outputs the incoming signal, which is generated from a handset at the time of the operation of the switch for incoming, to a transceiver unit 6 in response to the incoming detection signal. When a user will ring off in the speaking state, he operates an external switch 2 for ringing-off to output a ringing-off signal from the handset 5 to the transceiver unit 6 by the switch detector 3 and the switch function assigning circuit 4. Thus, it is sufficient if he operates only external switches to answer the telephone or ring off during driving, and it is unnecessary that he operates switches of the handset.

IPC: G05D21/00
Filed: 1993-09-14
Abstract: PURPOSE:To shorten a neutralization time while reducing the overshoot at a pH value regardless of the kind of a soln. CONSTITUTION:The concn. of a neutralizing agent contributing to neutralization is estimated and the absorption ration of the neutralizing agent, that is, the degree of electrolytic dissociation of a weak acid is calculated from the relation between the concn. of the neutralizing agent and the concn. of a hydrogen ion and, on the basis of the calculated value, the necessary feed amt. of the neutralizing agent is estimated to operate a neutralizing agent feed pump. Since the absorptivity of the neutralizing agent is renewed at every time, a neutralizing time becomes short. Since the time constant of stirring is considered, the overshoot of a pH value caused by the charging delay of the neutralizing agent is reduced.
