Patent JP-S6399406-A (JP)
Title: Kerosene combustion apparatus
Inventor: NITTA SATORU
IPC: F23D3/18
Filed: 1986-10-16
Abstract: PURPOSE:To heighten the cost performance of a kerosene combustion apparatus, by increasing the combustion capacity at high intensity combustion, as well as to alleviate bad odor at the time of shutdown of combustion, by rotating a fan in the reverse direction from that at the time of descending of a wick when the wick is raised to its maximum height, provided that a fan for alleviating bad odor at the shutdown time rotates forwardly or reversely. CONSTITUTION:When a combustion takes place on a wick 15 at its maximum height, a switch 26 is turned ON, a transistor 33 is turned ON, transistors 34, 35 and 36, 37 are turned ON, and a motor 24 for an air suction means 18 is actuated to drive a fan 23. At this time a voltage inverse to that at the time when a switch 25 is changed over to a normally-opened contact point 25a is applied to the terminal of a motor, so that the fan 23 is rotated reversely, and combustion air outside is sucked into an oil tank 11 through a passage 22, a fan case 20 and a suction port 19. The air sucked into the oil tank 11 is pushed up to a gap 14 within the wick and is fed into a flame cylinder 17. The evaporating rate of fuel on the wick 15 and the rate of combustion air are increased, as a result combustion capacity on the wick at high intensity combustion can be increased.

Title: Control method for inverter apparatus
Inventor: SATO SHINJI
IPC: H02M7/48
Filed: 1988-09-30
Abstract: PURPOSE:To control an apparatus with good accuracy and at high speed and further to improve the utilization factor of DC voltage of an inverter by controlling both DC/DC converter and inverter for keeping output voltage constant. CONSTITUTION:The output voltage value Vdc of a DC/DC converter 11 is detected by a voltage sensor 13. The ratio of the output voltage value Vdc to a voltage reference Vdc* obtained from a voltage reference generator 5 is obtained by a divider 14 and its output is added to a PWM waveform generator 12. Also, a phase reference theta* obtained from a phase reference generator 6 is added as an address to the PWM pattern generator 12. Then, the output voltage value Vdc is controlled so as to coincide with the voltage reference value Vdc*, but the output voltage value Vdc sometimes does not coincide with the reference value Vdc* transiently, e.g., when a command value is changed suddenly. Therefore it is required to select such PWM pattern as to change the ratio of the voltage reference Vdc* obtained by the divider 14 and the detected value Vdc of DC voltage. Thus, the output voltage can be made to quickly follow a desired value.

Title: Automatic original carrying device
Inventor: YAMADA YASUSHI
IPC: B65H7/06
Filed: 1989-09-20
Abstract: PURPOSE:To save the time required for processing of a jam by a method where in a feed time between the generation of a start signal for an original and detection of passage is detected, and when the feed time exceeds a reference time limit, through decision of the occurrence of the defective feed of a subse quent original, a jam signal is outputted. CONSTITUTION:A reference feed time in which an original is fed from a start position SO to a temporary stop position S1 is preset and stored in a control part. When the forward end part of an original D13 passes an original passage detecting sensor PS3 and/or an original passage synchronous sensor PS5, by detecting a spent time elapsing to completion of the passage, a necessary time for the feed of a sheet in which the forward end of the original D13 is carried to the temporary stop position S1 and stops thereat is estimated. When the necessary time in which a sheet is fed is longer than the reference feed time, it is decided that the feed of the subsequent original D13 is defective, and a jam signal is outputted to stop an original carriage operation. This constitution saves a time required for processing of a jam, and improves copying producibility.

Title: Image reader
Inventor: TOMARU NAOSHI
IPC: H04N1/04
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of defects, such as skipping of the top end part of an image, smear, color deviation by setting the pulse of a frequency higher than the starting profile of reference and the number of inputting pulses at a starting initial stage. SOLUTION: This reader is controlled by using the start-up profile of a stepping motor, setting the input of the frequency higher than the starting profile of reference and the number of the pulses at the starting initial stage. In the motor startup profile of reference, plural pulses higher than a pulse frequency used by calculation shown by dotted lines B and D are inputted only at the time of the start up of the motor. Namely, at the time of starting the motor, after starting at a speed sufficiently slower than a targeted speed, in a period longer than a pulse-switching time and a fixed speed, the rotation of the motor is accelerated to the targeted speed, while switching the input pulse similarly to the conventional manner. Decelerating tendency near the star-up is suppressed to sharply reduce the speed fluctuations in a fixed speed area.

Title: Clothing hanger
Inventor: KANO NAOTOSHI
IPC: A47G25/30
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent a pair of trousers or a skirt hung on a hanging frame from being slipped down by fitting the hanging frame equipped with a slip stopper to two supporters drooped from both the shoulders of the main body of a hanger so as to be freely revolved and preventing the hanging frame from being revolved by a revolution preventing mechanism. SOLUTION: When hanging a pair of trousers on a hanging frame 3, first of all, a strap-shaped manipulator 8 bridged between the main body of the hanger and the hanging frame 3 is manually held up to the side of the main body of the hanger, at such a time, a lock 6 is unlocked from a gear 5 of the hanging frame 3, and the revolution of the hanging frame 3 is turned into free state. Then, the hems of trousers are fitted onto the hanging frame 3 and pulled down until the trousers are almost folded in half while revolving the hanging frame 3. When the hand is separated from the manipulator 8 and the manipulator 8 is returned to be original, the lock 6 is engaged with the gear 5 of the hanging frame 3, and the revolution of the hanging frame 3 are stopped.  Therefore, in the state of stopping the revolution of the hanging frame 3, the trousers can be hung on the hanging frame 3 in stable state by the frictional force of a slip stopper 3b attached onto the hanging frame 3.

Filed: 1994-09-14
Abstract: PURPOSE: To obtain a positioning system by which a plurality of moving bodies are recognized without lowering the resolving power for distance in a repeater system out of positioning systems using a spectrum diffusion system. CONSTITUTION: Moving stations 31-1 to 31-4 are provided with respectively inherent codes PNI, PN2, PN3, PN4, and they send out response signals of own stations only when PN codes which are inherent in the own stations agree with receives signals by matched filters and switching circuits with which the stations are provided respectively. A fixed station 32 sends the codes PN1 to PN4 in a time-series manner so as to be put on carriers. The moving station 31-1 is provided with a discrimination code PN1, the code is matched to the code PN1 which is transmitted at a time T1, and a signal is returned to the fixed station. At this time, the other mobile stations 31-2 to 31-4 do not send out a signal because an output from the matched filter does not exist (the code PN does not agree). Then, the fixed station sends a signal PN2 to all the moving stations at a time T2, but only the moving station 31-2 returns the signal at this time. Consequently, the fixed station can search the moving stations which respond to a code sent by the own station.
