Title: Oxide semiconductor gas sensor
Inventor: SUGIE JUNJI
IPC: G01N27/12
Filed: 1990-02-21
Abstract: PURPOSE:To obtain the gas sensor which exhibits stable responsiveness by entangling whiskers with oxide particles and further depositing a noble metal thereon, thereby suppressing the grain growth of catalyst particles even at a high temp. CONSTITUTION:A small amt. of the SiC whiskers are added to titania paste and the paste is sufficiently mixed in such a manner that the whiskers mix uniformly with the titania particles at the time of preparing the titania paste. This paste is applied on an alumina substrate and is calcined. An aq. soln. of the salt of the noble metal (platinum) is added thereto and is thermally decomposed to produce the gas sensor. The SiC whiskers 3 exist to entangle with the titania particles 1 if the gas sensitive layer is formed in such a manner. Since the SiC whiskers 3 are bulky, the movement of the catalyst particles 2 is suppressed. The flocculation of the catalyst particles 2 by the heat during use is, therefore, substantially prevented.

Title: Speed controller for dc elevator
Inventor: ANDOU TAKEYOSHI
IPC: B66B1/30
Filed: 1978-04-05
Abstract: PURPOSE: To improve the speed control characteristics and reduce the size of a speed controller, by detecting the time of change in the acceleration or deceleration of an elevator and controlling an armature current.  
     CONSTITUTION: An acceleration differentiator 52, which differentiates the acceleration to generate an output, is coupled to the output of a speed generator 12. The output of the acceleration differentiator 52 is applied to a phase shifter 28 for an armature 8 so that the output is added to an instruction, which is applied by an armature current instructor 25. A part of the armature current is thus controlled as a function of the acceleration change rate. As a result, the armature current quickly responds to the acceleration change rate to improve the speed characteristics the armature current is increased to raise the torque and the delay in a field circuit is compensated to reduce the forcing factor of a field control power source 16. This makes it possible to reduce the capacity of a transformer 36 and the dielectric strength of a thyristor 17.

Filed: 1990-02-19
Abstract: PURPOSE:To exactly calculate a date by calculating the date while dividing the date into year and month or day and considering a leap year and long and short months. CONSTITUTION:For example, when calculating a period from January 8th 1989 to January 4th 1990, a control means divides the period into the year, month and day for the calculation and at first the days are calculated (4+31-8=27). Next, the months are calculated (12-1=11). Therefore, the period is exactly calculated to 11 months and 27 days. When the period of one month is added to February 1st 1990, the control means 17 calculates the year (1990+0=1990), calculates the months (2+1=3) and finally calculates the days (1+0=1). There fore, the date is exactly calculated to March 1st 1990. Namely, the leap year and the long and short months are considered, and an arithmetic processing is executed while dividing the first and second date and the period data showing the period into the year and month or day. Further, the calculated result is expressed while being divided into the year and month or day as well.

IPC: H04N19/176
Filed: 1991-02-08
Abstract: PURPOSE:To improve the picture quality and enable high-efficiency encoding by deciding the complexity of a pattern by areas of specific size of a video signal and controlling the step width of a means for quantization according to the decision result. CONSTITUTION:A block converting circuit divides a microblock MB into blocks BLK1-BLK4 and video data DV are supplied in the units of the blocks BLK 1-BLK4 by the A/D conversion 2 of a video signal SV. Then it is decided previously by feedforward in the units of blocks MB whether the signal SV has a complicate pattern or not, and for a complicate pattern block MB, a specific value is added to quantization step width. Then the quantization step width becomes large, so the amount of data generated in the block MB having the complicate pattern can be suppressed and much data are prevented from being generated protruding at the part of the complicate pattern. Consequently, an overflow is prevented, the picture quality is improved, and data quantized by a variable-length encoding circuit 6 can be converted into variable tone codes with high efficiency.

Filed: 1986-02-25
Abstract: PURPOSE:To estimate correctly the difference of phase between the symbol timing of the analog demodulation signal and a reference clock regardless of the value of the input phase difference, by eliminating the discontinuous points of the phase detection characteristics of a phase detector. CONSTITUTION:The detection outputs of plural times of a phase detector 1 are supplied to an absolute value circuit 2 for output of the absolute value of each detection output. Furthermore, the average of the absolute value of those detection outputs is calculated by an averaging circuit 3. While the positive and negative codes of the output the detector 1 are decided by a code deciding circuit 4 in parallel with those said actions. Then a majority circuit 5 decides the numbers of positive and negative codes contained in the output of the circuit 4. Then the circuit 5 outputs +1 in case the number of positive codes is larger then or equal to the number of negative codes and then -1 if the number of negative codes is larger than that of positive codes respectively. The detection output emerges only at the positive side (since the absolute value is secured) and therefore the discontinuous points are eliminated.
