Title: Synthesizer and reference signal generation circuit
Inventor: HONGO HIRONOBU
IPC: H03L7/16
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To make a band for frequency setting wider and to reduce frequency setting errors by inputting the output signal of a reference oscillator to a first phase synchronous oscillator, inputting the output to a second phase synchronous oscillator provided with a first variable frequency dividing means in a feedback loop and further inputting the output to a third phase synchronous oscillator outputting the signal of a desired frequency through a second variable frequency dividing means. SOLUTION: The output signal of a phase synchronous oscillator 21 which receives a signal from a reference oscillator 1 is inputted to a phase synchronous oscillator 23 as a local signal and is also inputted to a frequency divider 15. A signal obtained by dividing a frequency is inputted to a phase synchronous oscillator 22. A signal which is phase-synchronized with the reference oscillator 1 is outputted from the phase synchronous oscillator 22 containing a variable frequency divider 20 which finely adjusts the number of frequencies in an integer unit. The output signal is inputted to a variable frequency divider 2 which can roughly adjust the frequency, is frequency-divided and is inputted to the phase synchronous oscillator 23 as a reference signal. The frequency of the variable frequency divider 2 is changed and the output frequency of a synthesizer is toughly adjusted.

Title: Photographic silver halide emulsion
Inventor: OKAZAKI MASAKI
IPC: G03C1/08
Filed: 1986-03-15
Abstract: PURPOSE:To obtain a photographic silver halide emulsion having high sensitivity to color sensitization by dissolving a spectral sensitizing dye in water in the presence of an ether deriv. of cyclodextrin which makes the practically water- insoluble dye soluble in water so as to improve the stability of the dye. CONSTITUTION:An ether deriv. of cyclodextrin used is prepd. by etherifying a compound represented by the formula (where n is an integer of >=5) by the alkylation of hydroxyl groups in the compound. The hydroxyl groups at the 2- and 6-positions are preferably alkylated. For example, heptakis-2,6-dimethyl-beta- cyclodextrin has remarkably high solubility in water, so various advantages are expected. A spectral sensitizing dye used is preferably of nonion, betaine or cation type. The ether deriv. of cyclodextrin is used by an amount required to dissolve the spectral sensitizing dye and the preferred amount of the deriv. is 10-100 times the amount of the dye.

Abstract: PURPOSE:To obtain a brushless motor driving circuit which can shorten the starting time safely by controlling the relative position of a driving coil and a magnet rotor at the time of stoppage and conducting a specific driving coil according to the relative position at the time of starting. CONSTITUTION:A communication signal generating circuit 11 obtains a conducting timing of each driving coil based on counter electromotive forces induced in three-phase driving coils LU, LV, LW and delivers a switching signal for turning transistors Q1, Q2, Q3 ON/OFF. When a brushless motor stops from rotating state or starts from standstill state, switching signals are fed from a starting circuit 14 to the bases of the transistors Q1, Q2, Q3. Relative position of the driving coil and a magnet can be determined by conducting a specific driving coil when the brushless motor approaches from rotating state to standstill state and a driving coil is selected based on thus determined relative position at the time of restarting.

Title: Piezoelectric resonator
Inventor: TAKAHASHI HIROYUKI
IPC: H03H9/17
Filed: 1988-03-11
Abstract: PURPOSE:To omit a damping resistance which is used as an individual parts by setting the distance between a vibrating electrode part and an external connecting part at the value less than four times as much as the thickness of a piezoelectric substrate. CONSTITUTION:A vibrating electrode part A is formed at the center part of a strip-shaped piezoelectric substrate 1 with the short side part defined as an external connecting part B. The distance between both parts A and B is set at the comparatively small value less than four times as much as the thickness of the substrate 1. That is, the distance between the parts A and B is set at L together with the thickness of the substrate 1 set at (t) respectively. Thus in case of L<4t, the part B functions as a damping resistance with reduction of L and the effect of the dimpling resistance increases in terms of an exponential function. As a result, the part B, i.e., an end part of the substrate 1 functions as an equivalent damping resistance. Then the control of the phase characteristics, etc., is possible to the frequency of a piezoelectric resonator. Thus it is not required to add a special individual parts to the outside.

Abstract: PURPOSE:To draw a trace consisting of circles and straight lines at a high speed by calculating a pulse train previously on the basis of data on the trace to be drawn on the XY table and storing it previously, and reading the pulses at a specific speed and outputting them a pulse motor. CONSTITUTION:An input device 8 inputs data generated while the movement trace on the XY table 1 is decomposed into circles and straight lines and movement speed data on the XY table 1.

A pulse output device 11 outputs the stored pulse train from the storage device 10 to driving power sources 3X and 3Y at a speed specified by the input device 8. Consequently, the trace formed of the circles and straight lines is drawn on the XY table.
