Title: Phase angle detection unit
Inventor: YOSHIHARA TAKAO
IPC: G01R23/20
Filed: 1978-07-19
Abstract: PURPOSE: To measure easily the phase angle of a higher harmonic included in transmission and distribution lines by taking out the fundamental wave and the n- degree higher harmonic of an inputted ditorted wave and subjecting them to logical operation.  
     CONSTITUTION: The fundamental wave flowing on transmission and distribution lines passes through band-pass filter 2 and is applied to PLL circuit 4. PLL circuit 4 gives an n-degree higher harmonic, which agrees with the phase of the fundamental wave, to waveform shaping circuit 6 through band-pass filter 11. Meanwhile, the n-degree higher harmonic flowing on transmission and distsibution lines passes through band-pass filter 3 and is applied to waveform shaping circuit 7. As the output of AND circuit 9 which obtains AND between outputs of waveform  shaping circuits 6 and 7, a square wave having a pulse width proportional to phase difference can be obtained.

Title: Combustion control unit
Inventor: YOKOAJIRO YOSHIYUKI
IPC: F23N5/02
Filed: 1984-05-02
Abstract: PURPOSE:To suppress the change in the temperature of hot water at a transient time to shorten a setting time by setting to zero by a timer an output from a feedback operational unit for a predetermined period of time from the abrupt change of a necessary quantity of heat. CONSTITUTION:When the quantity of supply water abruptly changes at a time t1, heat of combustion is throttled to a point (l) by a heat quantity operational circuit 10 after a delay (tau) of a water quantity detector 3. Upon this occasion, when a heat quantity change detecting circuit 14 differentiates an output signal of a circuit 10 and detects any change which is more than the predetermined change, the circuit 14 produces an output pulse (h), and a timer 15 produces an output (i) for a period of time tau1 after the output pulse (h) is inputted. Since the output from the feedback operational circuit 12 becomes zero while the output signal from the timer 15 is being produced, the quantity of combustion keeps the value of (l) determined only by the output from the circuit 10. The time tau1 of the timer is set slightly longer than the time obtained by totaling the time constant of a heat exchanger and a delay due to the length of a pipeline up to a feed hot water detector 5. From the time t2 onward, the output of a circuit 12 becomes effective and quantity of combustion is corrected by an integration element, and reaches a stability at a time t3. Thus, it is possible to shorten the setting time up to reaching the stability.

IPC: H04M3/00
Filed: 1985-04-26
Abstract: PURPOSE:To simplify the maintenance of the regenerating system of station data condition by keeping a station data condition regenerating program independent from the address in the primary table of a station data. CONSTITUTION:A station data address list table 2 is prepared at a station data area (a station data part) in a switching on-line program other than several kinds of station data 1-n. It is assumed that the station data address list table 2 is a table which has a content of addresses of the primary table of each station and is the one that is not referred from the switching on-line program. The station data condition regenerating program recognizes memory addresses on the exchange of each station data by reading the table. When a document is regenerated from the station data that is the data of the switching on-line program, for the first, the station data address list table is read and from this, the address in the primary table of the station data is taken out. Based upon a taken out address, the document is regenerated following the station data from a master (the primary table) to a slave (a lower grade table).

Title: Optical system
Inventor: KATAOKA KEIJI
IPC: G11B7/125
Filed: 1983-05-23
Abstract: PURPOSE:To form a minute circular spot on a disk, by using a light source, i.e., a semiconductor laser having an output light distribution of an oval beam pattern and having more number of longitudinal light distribution patterns than the lateral light distribution patterns. CONSTITUTION:An output angle u2 of the semiconductor laser given from a light source 1 is set at a value which can secure the half value width of a lateral far viewfield image of the semiconductor laser. As a result, the output light distribution of the semiconductor laser is formed approximately into a circle within the angle u2 and both in the longitudinal and lateral directions. Therefore, the light distribution which is made incident to a lens 3 is also circular, and furthermore, a stopped-down spot 4 is circular, too. Thus it is possible to have a circular stopped-down light spot by using a semiconductor laser light source having different longitudinal-lateral ratios of light emitting regions which can obtain a comparatively large optical output. The good reproduced signals are obtained from a disk.

Title: Error correction device
Inventor: KIMURA TOMOHIRO
IPC: H03M13/00
Filed: 1987-04-10
Abstract: PURPOSE:To decrease the capacity of a ROM by using only one residual code of two dividers for a residue code given as an address of the ROM in case of using the ROM for a code converter and using a coincidence detector so as to compare the residue code outputted from the other with the output of the code converter so as to generate a correction signal. CONSTITUTION:A signal is given from a terminal 8 to dividers 1, 2 via a delay device 6 and a selector 5. The divider 1 uses a 1st irreducible polynomial being the primitive polynomial to apply division at a point of time of the input of one code and the divider 2 uses a 2nd irreducible polynomial to output residue codes R1, R2 respectively. The value R1 is converted by a code converter 3. The conversion code is compared with the R1 by a coincidence detector 4. When the R1, R2 are dissident, no error correction code is outputted and a 1st bit signal outputted from the delay device 6 is outputted as it is from a terminal 9 via a bit inverter 7. Succeedingly, the delay device 6 and the dividers 1, 2 are operated for one clock and a 2nd and succeeding bit signals are processed similarly. Through the constitution above, the error bit in the code is corrected and the residual code for address input of the ROM is unified to decrease the capacity of ROM.
