Title: Method and mechanism of positioning paper sheet in optical reading device
Inventor: MATSUI NOBUYUKI
IPC: G06K9/20
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To make positioning without occurrence of misconveyance of a sheet of paper using a simple configuration. SOLUTION: The leading edge of a sheet of paper 3 fed by a feed roller 5 follows a sheet feeding path between paper guides 8 and 9 and runs against a nipping part between a drive roller 6 and a pressure roller 7. The feed roller 5 is driven farther even after this collision with the nipping part, and thus the middle part of the sheet 3 is deflected along an approximately L-form groove furnished in the paper guide 9. Thus the warp or curl at the leading edge of the paper 3 is corrected, and the paper 3 is given a higher stiffness to ensure better biting-in, thus leading to the prevention of a misconveyance, and also a skew is corrected.

Abstract: PURPOSE:To attain effective utilization in a relay line and in a transmission capacity of highway by adopting multi-frame constitution for the signal constitution sent to the highway and the relay line so as to decrease redundancy information such as ineffective information attended with the transfer of information. CONSTITUTION:A signal sent from a voice compressor (a) and a data transmitter (b) is mixed in time division with other information on the transmission highway (e) and the result is sent to a time switch group (d). The information of the compressor (a) and the transmitter (b) is replaced into another time slot and another frame by the time switch group (d) and appears on a reception highway (f). The information on the compressor (a) and the transmitter (b) appearing on the highway (f) is transferred to an opposite station time division multiplexer via a relay line (c). Since a multi-frame signal of the own station is sent to an opposite station and a multi-frame signal of an opposite station is sent to the own station between multiplexers, the information from the opposite station is transferred to the compressor (a) and the transmitter (b) via the relay line (c).

Title: Neutron flux measuring instrument
Inventor: FUJISHIMA YASUTAKA
IPC: G21C17/10
Filed: 1985-04-12
Abstract: PURPOSE:To make compact the titled instrument by supplying a bias voltage to plural pieces of neutron flux detectors with a piece of bias power source. CONSTITUTION:Electric current flows between an anode and cathode when neutrons are made incident to a fission ionization chamber 101 (101a-101n). The output current signal thereof is inputted via a signal transmission path 102 (102a-102n) to an amplifier 103 (103a-103n). The amplifier 103 converts the current signal from the chamber 101 to the voltage signal proportional thereto. The output voltage signal is the fluctuation signal of which the reference value is a high voltage. Since this signal cannot be inputted directly to the next stage of an arithmetic circuit 201, the signal is inputted thereto via an insulating circuit 104 (104a-104n). A variable resistor 105 (105a-105n) is used to adjust the gain according to the deterioration in the sensitivity of the chamber 101. On the other hand, one bias power source impresses the bias voltage to the respective chambers 101 via the amplifiers 103. The instrument is thus made compact.
