Title: Active noise canceler
Inventor: SAEKI TAKAFUMI
IPC: H04R1/10
Filed: 1989-02-25
Abstract: PURPOSE:To prevent production of howling in an audible range and to improve the noise eliminating performance by arranging a monitor microphone to a position of a side face of a noise eliminating speaker and a position where a cancel tone radiating from a positive pressing face of the noise eliminating speaker and a cancel tone radiating from a negative pressing face are canceled together. CONSTITUTION:A monitor microphone 2 is placed to a position close to the side face of the noise eliminating speaker 1 and a position where a cancel tone radiating from a diaphragm surface 1e (positive pressing face) of the noise eliminating speaker 1 and the cancel tone radiating from a housing surface 1f (negative pressing face is canceled with each other. When the active noise canceler is used in a place such as a cockpit of an aircraft having external noise, the external noise is inputted by the monitor microphone 2, a noise cancel circuit 3 generates a cancel tone generating signal of the opposite phase to the input signal, the cancel tone radiates toward the ear shell E of the user from the noise eliminating speaker 1 based on the signal and the external noise listened to by the user is eliminated through the canceling action of the opposite phase by the cancel tone.

Title: Controlling method for sheet feeding of printer
Inventor: DOBASHI KOICHI
IPC: B41J29/48
Filed: 1990-02-26
Abstract: PURPOSE:To check whether or not a transported sheet is qualitatively satisfactory and make possible appropriate sheet feed by manually selecting a sheet attached to each tractor wheel and displaying an error when a selected sheet and a sheet transported to a printing position are different. CONSTITUTION:Sheets 5a, 5b attached to tractor wheels 6, 7 can be transported to the same printing position between a platen 2 and a printing head 3 by driving selectively a motor for the first tractor wheel 10 and a motor for the second tractor wheel 11 and thereby driving a drive shaft 8 to rotate and driving tractor pins of the second tractor wheels 6, 7. In addition, selection is made between tractor wheels 6, 7 and sheet feeders 12 by operating a selector lever from the near side. Further, a selector lever sensor detects which sheet 5 is selected in a control part provided on a printer. Next, the manually selected sheet 5 and the sheet 5 transported to a printing position are compared. If the sheets are of the same type, data continues to be printed on them. On the other hand, if the sheets are different from each other, printing is not performed and an error indication is made.

IPC: H01L29/78
Filed: 1983-03-15
Abstract: PURPOSE:To prevent a portion between a drain region and a substrate from generation of an inversion region, and to prevent the portion from generation of conduction at an MOS semiconductor device by a method wherein a shielding conductor is interposed at a portion on a well between the drain region and the substrate to be crossed with a drain output signal line. CONSTITUTION:A shielding electrode 12 is formed on the surface of a field oxide film 6 on an n<-> type well 2 between a drain region 4 and a p<-> type semiconductor substrate 1 crossed on with a drain output signal line 10, and arbitrarily fixed electric potential between electric potential of the p<-> type substrate and electric potential of a source electric power source is applied to the shielding electrode 12 thereof. Accordingly, action as an MOST is the same as usual. When a negatively high voltage is applied to the drain output signal line 10, an electric field generated according thereto is shielded by the shielding electrode 12 not to reach a portion between the drain region 4 and the p<-> type semiconductor substrate 1, accordingly because the portion thereof is not inverted to a p type, conduction is not generated between the drain region 4 and the p<-> type semiconductor substrate 1.

Title: Dc arc welding and welding machine
Inventor: HAGIWARA SEIGO
IPC: B23K9/06
Filed: 1982-03-19
Abstract: PURPOSE:To lessen shortcircuit current and prevent generation of spatter, by gradually decreasing output current for a specified time after generation of an arc between a wire fed at nearly constant speed and a base metal, and gradually increasing output current after short-circuiting until generation of an arc. CONSTITUTION:A transistor 3 is made off by output of the first rectifier circuit 1 a specified time after generation of an arc in a welding load 5 connected in series to this through a transistor 3 and a reactor 4, and made on further after a specified time. Output current decreases gradually after generation of an arc and after the transistor 3 is made off, further decreases slowly from the value of output voltage of the first rectifier circuit 1 to voltage of the second rectifier circuit 2 connected in parallel with small output voltage. When the transistor 3 is on, voltage rises slowly to output voltage of the first rectifier circuit 1, and output current also increases gradually. By this way, heat inputting is made as far as possible after generation of an arc until next shortcircuit to facilitate regeneration of arc and suppress generation of spatter.
