Title: Limiter amplifier
Inventor: SHIMADA SHUSAKU
IPC: H03G11/02
Filed: 1986-02-18
Abstract: PURPOSE:To obtain a limiter amplifier which drives a parallel A/D converter suitably without using any unity stable operational amplifier by providing a feedback means which controls the swing of an operational amplifier to the positive and negative sides and a feedback means which feeds back the limit level of the operational amplifier. CONSTITUTION:A resistance R2 and a diode D2 constitutes the 1st feedback means for the operational amplifier A and a diode D3 and a Zener diode ZD constitute the 2nd feedback means. A connection point 2 is connected to a common line through a resistance R3. The 1st feedback means prevents the output of the amplifier A from swinging to the positive side and the 2nd feedback means reduces the node impedance of the amplifier A and also inhibits the output from swinging the output from swinging to the negative side. Resistances Ra and Rb and a voltage source +V constitute a level setting circuit for an output limit, and a transistor TR constitutes an output buffer while its output is fed back to the amplifier A through a resistance Rf. Consequently, negative feedback is provided to the whole of the amplifier A and an output buffer to obtain a desired gain. For the purpose, the values of the resistances R2 and R3 are selected properly and the amplifier A does not oscillate even when not a unity stable amplifier, obtaining excellent limit characteristics.

Abstract: PURPOSE:To align an original with photosensitive paper securely without reference of the material and thickness of the original, by enabling the original to move freely by slipping adequately by applying small carriage force along a tip alignment member provided so that it can move in and out. CONSTITUTION:Original 0 is circulated repetitively in the circulation path including an exposure part and at every time of the circulation, it is carried to the exposure part by being superposed upon photosensitive paper S fed out of an automatic paper feeder at a prescribed position to take copies of the original. In this case, when original 0 returning from repeat device 40 and photosensitive paper S sent by paper feed roller 28 are superposed mutually at conflux point A and then advances to a point right before stop plate 26 by feed rollers 24 and 25, feed roller 25 separates from roller 24 and stop plate 26 is displaced to the dotted-line position to cut off the carriage path. Then, original 0 and photosensitive paper S are carried by carrying roller 53 and paper feed roller 28 respectively and their leading edges are aligned to each other by stop plate 26.

Abstract: PURPOSE:To decrease an output loss with a high output by providing a labyrinth slip in the periphery of right and left crank wheels to approach a crank chamber internal wall, balance hole hollowed from the outside in the crank wheel and an oil seal in the inside of a crankshaft. CONSTITUTION:A labyrinth slip 5 is provided in the periphery of right and left crank wheels 1 to approach an internal wall of a crank chamber 6, a balance hole 11 is provided so as to prevent its penetration being hollowed from the outside of the right and left crank wheels 1 and right, and left crankshafts 3 are rotatably mounted to a crank case 9 by bearings 8 arranging oil seals 7 inside. By this constitution, primary compression ratio is increased by decreasing the crank chamber volume used for primary compression, and a high output can be obtained by increasing charging efficiency of intake air to a cylinder. The right and left oil seals 7, which are placed outside the labyrinth slip 5 with a less fluctuation of pressure, are sufficient in small size for preventing leakage of lubricating oil thus to enable a loss of the output to decrease.

Title: Current lead of superconductive device
Inventor: TAKITA KIYOSHI
IPC: H01F6/00
Filed: 1993-02-24
Abstract: PURPOSE:To prevent an oxide superconductor from deteriorating in characteristics due to moisture attached to it. CONSTITUTION:A check valve 5, which prevents gas from flowing into a liquid helium vessel from a low temperature side lead 22, is provided to a channel 213A bored in a connecting piece 212A of a low temperature terminal 21A.

When no dry gas is fed from outside while liquid helium is turned into helium gas, helium gas may flow into the current lead from the liquid helium vessel passing through the check valve 5, and the current lead is filled with gas fed from outside while no helium gas is produced. At this point, gas is prevented from flowing into the liquid helium vessel by the check valve 5.

IPC: H04N9/43
Filed: 1995-02-22
Abstract: PURPOSE: To prevent the picture disturbance and the variance in brightness by performing such control that the horizontal synchronizing signal of a face sequential signal is continuous with a fixed period. CONSTITUTION: Three primary color signals R, G, and B are converted into a face sequential signal M having a three-fold input speed by a face sequential signal generator 1, and this signal M is outputted. It passes a monochromatic picture display device 4 and is colored by a coloring device 5 to obtain a color picture. A control circuit 3 controls the generator 1 and devices 4 and 5 based on a reference clock CK and horizontal and vertical synchronizing signals HD and VD. At this time, the circuit 3 controls the storage device of the generator 1 so that n-fold horizontal synchronizing signals synchronized with n-fold plural primary color signals as the output are continuously outputted at equal intervals.  Thus, horizontal synchronizing signals are continuously arranged at equal intervals with respect to the signal M; and therefore, AFC is free from malfunction even when a monochromatic CRT of the device 4 is used, and horizontal scanning is continuously performed, and the high voltage generated by a flyback transformer is stabilized and outputted.

Title: Radio telephone set
Inventor: HARA TOSHIHIRO
IPC: H04W36/08
Filed: 1992-02-21
Abstract: PURPOSE:To eliminate the need for a reception level detection means of the radio telephone set by comparing numerals of a reception level signal sent from a radio connection device so as to select a radio connection device in a zone with a large reception level. CONSTITUTION:Upon the receipt of a manual and automatic position registration signal from a radio telephone set 4, a reception level detector of a radio connection device discriminates the signal to be a numeral and the connector 3 sends a reception level signal to the telephone set 4. The telephone set 4 is in radio connection to a connector 3 in a zone with a highest level of the received reception level signal from the connectors 3 among zones A-C and registers the position to the radio line controller 2. When the registration is finished, the controller 2 sends a registration end signal to the telephone set 4 through the controller 3 in radio connection with the telephone set 4 and the telephone set 4 stores the controller 4 in radio connection. Thus, no reception level detection circuit is required for the telephone set 4. Moreover, the manual position registration flow and the automatic position registration flow are enough to be the same position registration flow and the software is simplified.
