Title: Cassette interface
Inventor: KADOSAWA TSUNEAKI
IPC: H03M5/12
Filed: 1980-04-11
Abstract: PURPOSE:To increase the transfer speed of data by converting the waveform inputted from a cassette tape recorder to the waveform on the basis of the midpoint of said waveform and frequency-modulating the same through a demodulating circuit. CONSTITUTION:The reproduced output of a cassette tape recorder 1 is applied with peak holding by a peak holding circuit 3 and the midpoint of the reproduced waveform is obtained by a midpoint detecting circuit 4 by using these peak values. A comparator compares the magnitude between this midpoint and the reproduced output continuously, outputs the results thereof and inputs the same to a demodulator  2. Hence, the frequency-modulated data are accurately demodulated by the demodulator 2. This makes it possible to increase the modulating frequency or decrease the frequencies of the waveform constituting one bit. With such constitution, the transfer speed of the data is increased.

Inventor: SAITO NAGAO
IPC: B23H1/10
Filed: 1990-02-28
Abstract: PURPOSE:To keep the distance between electrodes constant irrespective of the shapes and kinds and to improve the working accuracy by measuring the distance between electrodes properly under working, and controlling one or plural fluctuation factors between electrodes according to the difference in the distance between electrodes and a target distance between electrodes. CONSTITUTION:The body 2 to be worked is worked by interposing the work liquid 4 in which powders are mixed between the electrodes of an electrode 1 and the body 2 to be worked. In this case, the distance between electrodes is measured at proper time under working and one of plural fluctuation factors between electrodes are controlled according to the difference in the distance between electrodes and a target distance between electrodes. For example in the case of the distance between electrodes being small, an NC device 13 makes a target servovoltage value larger. Consequently, the distance between electrodes is held constant irrespective of the fluctuation factors between electrodes of a powder state of the powder grain size, density of the powder mixed work liquid, etc., the powder shape, the powder kind, etc., and the working accuracy is improved.

Title: Pressure detector
Inventor: FUKUI AKITO
IPC: G01L23/10
Filed: 1986-03-05
Abstract: PURPOSE:To detect variation on static pressure accurately and to obtain a relatively small-sized pressure detector for high pressure by providing two electrostrictive elements for pressure detection and temperature compensation in a housing. CONSTITUTION:An electrostrictive element 1 is arranged in the housing 11 whose inside is formed in a bag shape and an electrostrictive element 2, on the other hand, is arranged opposite the top surface side of the element 1 while made of the same material with the element 1 and having the same temperature coefficient. A diaphragm 9 seals the entrance part of the housing 1 and a rod 10 as a pressure medium is arranged between the diaphragm 9 and element 1. Consequently, pressure applied to the diaphragm 9 is transmitted to the element 1 through the rod 10 and the element 1 varies in electrostatic capacity C with the pressure because of reverse electostriction effect. The element 2 also varies equally in capacity C with temperature and the both cancel each other, so that the variation in the capacity C is compensated. Further, while the pressure is applied, the value of the capacity C corresponding to it is maintained because of the properties of the electrostrictive elements and static pressure variation is detected.

Said paper is exposed and cured selectively according to the reflected light beams respectively selectively passed through three kinds of filters 5. The photosensitive pressure-sensitive paper is carried to fixing rollers 10 after the exposing, by which the unexposed capsules are crushed and the materials included therein penetrate the paper to form colors. The excess color forming agents such as ink are sucked away by the capillarity of the fine pores 10a of the rollers 10 and are further absorbed by the ink absorbent 10b. The always clean image is thereby formed on the recording medium.

Filed: 1989-02-28
Abstract: PURPOSE:To obtain accurate sway data by correcting a decrease in output due to phase delay behind the swaying period of the detection signal of an inclination measuring sensor which is found previously according to the correlation between the detection signal and the swaying period. CONSTITUTION:Correction coefficients as correction data for the decrease in the output amplitude of an inclinometer 14 are written previously in a correction table 36 corresponding to the swaying period. Then the detection signal of the inclinometer 14 corresponding to the inclination degree of sway is converted by an A/D converter 26 into a digital value under the command of a controller 34 and the digital signal is stored in a memory 28. Then a Fourier transformation part 30 reads data out of the memory 28 and performs Fourier transformation and a spectrum analytic part 32 finds a spectrum indicating the relation between the frequency and intensity and sends it to a spectrum correction part 38. Then the correction part 38 reads a correction coefficient out of the table 36 and multiplies the spectrum, found by the analytic part 32, by the correction coefficient to calculate a correction spectrum, and a sway data arithmetic part 40 calculates the mean period, maximum inclination degree, etc., which are displayed on a display device 16.

Then, the value of the pressure in the suction pipe at the future time point when the jetted fuel reaches a combustion chamber, i.e. at the future time point is estimated by using the estimation value and the transmission characteristic. Then, the fuel injection quantity is calculated by using the estimation value.
