Title: Leading-in detecting circuit of autofocus servo
Inventor: KONDO JUNICHI
IPC: G11B7/09
Filed: 1984-10-02
Abstract: PURPOSE:To lead in accurately the focus servo on the surface of a recording medium even in case of the input of an erroneous signal by outputting a detection output to close the servo loop when two pulses of a comparator appear in one cycle. CONSTITUTION:The difference of the output of a focus sensor 4, which detects whether the distance between a focus actuator 1 and a disc is proper or not, and the surface oscillation of the disc accompanied with rotation is inputted as an error signal A to a driver 2 and a control circuit 7. The signal A inputted to the circuit 7 is inputted to one input terminal of a comparator 12 of an incorporated leading-in detecting circuit and is compared with threshold voltages VTH and VTH' in the other input terminal. If two pulses appear in the output waveform while the actuator 1 is moved back and forth once, leading-in detection outputs E and G are outputted to a switch 6 through a counting circuit 13 to close the servo loop accurately.

Title: Liquid fuel combustion apparatus
Inventor: KUBOTA YUKO
IPC: F23D11/02
Filed: 1994-08-31
Abstract: PURPOSE: To prevent temperature of a nozzle from being raised by providing a secondary air port for supplying secondary air to a flame port for combusting mixed gas, and fixing the nozzle to a primary air passage, and leading an oiling pipe from the inside of the primary air passage to the outside of an air fan passage to couple the same to a pump. CONSTITUTION: A vaporizer 18 is kept at high temperature with an electric heater 19 such that a liquid fuel is heated and vaporized. A nozzle 16 of the vaporizer 18 is air-cooled owing to combustion air being fed during combustion while temperature of the nozzle is raised owing to the combustion air being not fed upon non-combustion. However, since the nozzle 16 is fixed to a primary air passage 22 and a mount part 27 is provided outside the primary air passage 22, heat from the nozzle 16 that becomes high temperature is dissipated to the primary air passage 22 and a secondary air passage 23 through heat conduction.  Further, since an oiling pipe 17 that couples the nozzles 16 and a pump 15 has a large outer diameter from the nozzle 16 to the air fan passage 21 and is thick-walled, the heat from the nozzle 16 is dissipated from the oiling pipe 17 to the outside of a combustion apparatus through heat conduction and hence the temperature of the nozzle 16 is prevented from being raised.

Title: Power source circuit
Inventor: NAGAO SHINICHI
IPC: H02M7/12
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce a power consumption by adding a switch between a main power source switch and a stand-by power source, and intermittently supplying a power to the stand-by power source by continuously opening and closing. SOLUTION: A main power source switch 1 is operated, and a subswitch 2 is operated. When the sub-switch 2 is opened, a voltage starts lowering, but a stand-by power source circuit 13 continues operating until an applied voltage is lowered to a stopping voltage. When the voltage is lowered slightly from a reference voltage, an output voltage of a comparator is simultaneously inverted to trigger a one-shot multivibrator to thereby set an output of the multivibrator to an 'H'. Then, the 'H' output of the multivibrator is applied to a relay switch to turn ON the relay switch, and its voltage is raised. When the output of the multivibrator is changed from the 'H' to an 'L', the relay switch is opened, and the voltage starts lowering. When the voltage is lowered from a reference voltage, an output of the comparator is inverted, and the relay switch is repeated ON and OFF.  Thus, its switching loss is reduced, thereby decreasing its power consumption.

Title: Deciding method for application time point of power supply in floor heating system
Inventor: ISHII JUN
IPC: G05D23/24
Filed: 1986-09-03
Abstract: PURPOSE:To attain a fully automatic floor heating system in response to the external movement like the open air temperature, etc., by using the data on the weather conditions and open air temperature measured before heating after comparing them with the open air temperatures measured before heating. CONSTITUTION:The open air temperatures are periodically detected by a open air temperature sensor 4 and measured by a temperature measuring circuit 5. These measured temperatures are stored in the temperature memories 31-3n via an A/D converter 7. The data stored in the memories 31-3n are integrated by an arithmetic circuit 9 with each addition of new data. This integrated value is sent to an open air temperature mode deciding part 10 and the part 10 decides the specific one of those open air temperature modes stored in an open air temperature memory 1 that corresponds to said integrated value. Then the decided temperature mode is sent to an application time point deciding circuit 11 and compared with the temperature increase characteristics stored in a temperature increase memory 2. The application of power supply is controlled so that the temperature reaches a desired level at a target time point.

Title: Magneto-optical disk
Inventor: TOBISAWA TAKESHI
IPC: G11B11/10
Filed: 1989-08-10
Abstract: PURPOSE:To easily change the optimum intensity of laser light for reproducing without changing the composition of a recording film by providing a sensitivity- controlling metal film essentially comprising Ti. CONSTITUTION:A sensitivity-controlling film 4 essentially comprising metal titanium is provided on the opposite side of laser incident side adjacent to the recording film 3 which essentially comprises rare earth-transition metal. The film 4 is made 100 - 1,000Angstrom thick. By this constitution, the heat produced in the recording film 3 due to laser light from the substrate 1 partly transmits to the sensitivity-controlling film 4, which limits temp. rising of the recording film 3. On recording in the recording film 3, higher intensity of laser light is needed compared to a medium without having a sensitivity-controlling film, and on reproducing, the recording film 3 is also heated. However, increase in temp. can be suppressed and reduction of Kerr rotation angle can be prevented. The effect of heat conduction can be controlled by changing the thickness of the sensitive-controlling film 4. Thereby, without changing the composition of rare earth-transition metal in the recording film 3, the optimum intensity of laser light for reproducing can be easily changed.

When the recognized character string is not present on the dictioonary part, character recognition is repeated until the character string for which the character recognition part 21 is recognized again by substituting it for the other character string whose contour is near with the character string in the dictionary part 3.

Title: Temperature control device for air conditioner
Inventor: HIGASA KIMIHIKO
IPC: F24F11/00
Filed: 1982-11-27
Abstract: PURPOSE:To perform delicate temperature and humidity controls by a method wherein a compressor stopping time is set on the base of a temperature gradient during the operation of the compressor immediately before stopping and when the room temperature reaches a thermo-ON point or a thermo-OFF point, the operation of the compressor is started or stopped. CONSTITUTION:An initial compressor operating time t1 is determined unconditionally by a microcomputer 9 on the base of the temperature gradient during a first compressor stopping time and a second compressor stopping time T2 is determined unconditionally on the base of the temperature gradient during the initial compressor operating time. When the room temperature reaches the thermo-ON point during a third compressor stopping time, an electromagnetic switch 8a is closed by the microcomputer 9 and the compressor begins to operate until the room temperature reaches the thermo-OFF point at which the temperature control by the microcomputer 9 based on the temperature gradient is initiated again. Therefore, it is possible to control the width of variation of the room temperature below the difference between the thermo-ON point and the thermo- OFF point if the compressor operating and stopping times are set favorably.
