Title: Cleaning method of fine drilled hole
Inventor: INOUE KATSUMI
IPC: B23Q11/00
Filed: 1982-02-01
Abstract: PURPOSE:To remove foreign substances inside a drilled hole together with a filler, by filling up resin in a fine drilled blind hole, while solidifying the resin in a state of wrapping up these foreign substances including burrs, chips and the like altogether inside the hole and then removing the solidified resin out of that hole. CONSTITUTION:Resin 10 is filled up in a tapped hole 6 and solidified later. Foreign substances including a burr 8, a barb 9 and the like are wrapped up into the resin and solidified later whereby they come into a unific state together with the resin 10. A slot 11 is made atop the resin 10, in which a screw driver is fitted and rotated in an unscrewed direction so that those of burrs, barbs, other chips and the like are all taken out of the hole in a state of what they are wrapped up within the resin as one body; thus a blind hole without any extraneous substances inside can be secured.

Title: Method for automatically sampling page number
Inventor: HATSUTORI TAKAHARU
IPC: G06F17/21
Filed: 1993-02-01
Abstract: PURPOSE:To make it unnecessary to reallocate page numbers allocated once by adding a branch number to the final page when the number of pages is increased at the time of allocating page numbers and adding a deleted page number to the final page to print out it. CONSTITUTION:Page numbers are allocated in the order of content items and the initial and final page numbers are added and stored. When the number of pages is increased from the initial one at the time of updating and printing out an optional module, a page number is added to the increased page part by adding a branch number, and when the number of pages is reduced in a module, the page reduction is printed out on the final page. In the case of printing out a module preceding a deleted page, reduction in the number of pages is similarly printed out in the final page. Consequently it is unnecessary to realocate page numbers allocated once.

Title: Amplifier circuit
Inventor: ASAI KATSUO
IPC: H03F3/30
Filed: 1983-01-31
Abstract: PURPOSE:To reduce power consumption by generating a constant current output according to the driving condition of an output transistor (TR). CONSTITUTION:When an input signal S is in a negative half cycle, a TR40 for electric power is off and a TR42 for electric power is on. A base current is supplied from a constant power source 46 to the base of the TR42 through a TT44. The collector current of the TR44 determines the collector current of a TR56 to determine the current flowing through a diode 54. A constant current IS corresponding to the current flowing through the TR54 flows through a TR60. This current is added to the current IO of the constant current source 46 and the sum signal is supplied to the base of the TR42. When there is no signal, only the current IO flows, and when the input signal arrives, the current IO+IS flows. Consequently, sufficient driving force is obtained even when the current IO is made small to reduce the power consumption in idling operation.

Title: Detector for microwave object position
Inventor: HIROYA HIKARI
IPC: G01S7/02
Filed: 1978-02-13
Abstract: PURPOSE:To establish the micro wave object position detector, eliminating mis- detection due to unnecessary reflected microwaves, by utilizing circular polarized waves. CONSTITUTION:The straight line polarized waves from the microwave oscillator OS is converted into circular polarized wave with the circular polarized wave generators CG and radiated from the transmission antenna AN1. At the reception side, the straight line polarized generator DG converting the circular polarized wave into the straight line polarized wave is inserted between the reception antenna AN2 and the detector DE. The waves directly propagated from the transmission antenna AN1 to the reception antenna AN2 have the direction of revolution which is radiated from the transmission antenna AN1, but the reflected waves from the object 1 have opposite direction. Since the direction of polarization is different for the direct and reflected waves for the straight line converted, the coupling between DG and DE is constituted so that only the staright line polarized waves can pass through, then allowing to give the microwave energy of direct waves to DE.

Abstract: PURPOSE:To align papers by a simple construction for an automatic paper aligner used for a recorder by changing a paper holding force produced by drive and driven rollers to cause a slip between the papers. CONSTITUTION:A drive roller 5 is mounted on a drive roller shaft 12. The shaft 12 is connected with a paper feed motor and feeds a paper 8. A driven roller shaft 13 is connected to a drive member 14 connected at one end thereof to a motor 16.

In normal paper feed, the paper 8 is fed as sandwiched between the drive and driven rollers 5 and 6, respectively. In paper alignment, the drive roller 5 is rotated in a given direction and in a given speed. At this time, slip is caused between the papers 8 by decreasing the force for holding the paper 8.
