Title: Frequency hopping transmission method
Inventor: SAWAHASHI MAMORU
IPC: H04B1/713
Filed: 1995-01-06
Abstract: PURPOSE: To realize demodulation capable of absolute synchronous detection in a high-speed frequency hopping transmission method which switches the carrier frequency of information over a wide band. CONSTITUTION: The transmission side generates and transmits the frame constitution where a pilot signal having a known pattern is periodically inserted into the information data signal at intervals of several symbols. The reception side converts the input signal to a signal having center frequency 0 in accordance with the hopping pattern by frequency conversion (105, 104, and 103). Phases of respective chips are obtained and averaged in a continuous pilot section to obtain the error (106). In an information symbol section, amplitudes and phases at chips in the same carrier frequency in each symbol are compensated in accordance with the information symbol section position by interpolation based on the obtained error (108). Phase compensated signals of respective chips in one symbol are synthesized in the same phase (109), and the synthesized signal is discriminated and judged (110).

Patent JP-H08190136-A (JP)
Title: Camera system
Inventor: TSUKAMOTO TAKEYA
IPC: G02B7/28
Filed: 1995-01-09
Abstract: PURPOSE: To prevent work for confirming a shadow state made in a subject by normal light emission before photographing from being interrupted even when operation for designating the setting of a subject image state is performed in the midst of test light emission by constituting a camera system so that action for setting the subject image state can be controlled. CONSTITUTION: In the case autofocusing operation is performed in the midst of the test light emission, a microcomputer 1B controls the autofocusing action of a focus driving part 3 so that the action being the cause of changing a focusing state is restricted so as not to change the focusing state in the midst of the test light emission by limiting pitch in order to reduce the detection region of a focusing area and inhibiting a low contrast scanning action. Therefore, even when the condition of autofocusing action is changed between at the time of autofocusing operation and at the time of starting the test light emission, a user confirms the same focusing state as that at the time of starting the test light emission through a finder FR.

Patent MX-158541-A (MX)
Inventor: PHELAN JAMES JOSEPH
IPC: G01S15/60
Filed: 1985-11-14
Abstract: A transmitter (22) emtis a signal at the frequency of an oscillator (32). A reference phase-locked loop (34) provides a corresponding reference velocity voltage (Vt). The reflected signal is received by a receiver (24) and processed by a second phase-locked loop (48) which provides a Doppler velocity votlage (Vr) which is corrected by subtracting (58) the reference voltage (Vt). In order to avoid spurious response by the second PLL (48) a drop-out detector (46) provides a drop-out signal (D/O) when the amplitude of the received signal (fr) is below a threshold (Vth). The drop-out signal causes a low-pass filter (52) in the second PLL (48) to hold its output unchanged for the duration of the drop-out. A digitally implemented embodiment is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE          A 3-hemisulphate sodium salt of a 17.alpha.-hydroxy steroid which is estrogenically effective, and having the general formula   is produced by treating a 3-hydroxy-17-acyloxy steroid of the general formula   with sulphur trioxide or a sulphur trioxide-containing agent in an organic nitrogen compound, preferably pyridine, and converting the resulting product into the corresponding sodium salt by treat-ment with an alkali, preferably sodium alcoholate or sodium hydrox-ide in a lower alcohol, with simultaneous saponification.  In the above formulae R1 represents hydrogen, methyl or ethyl and R2 represents an acyl radical containing up to 15 carbon atoms, and the rings B and C can contain additional double bonds.  For example, 17.alpha.-acetoxy-1,3,5(10)-estratrien-3-ol is treated with sulphur trioxide in the presence of pyridine, and the resulting product is treated with sodium methylate/methanol to produce 17.alpha.-estradiol-3-hemisulphate sodium.
