Title: Device for reducing impulsive noise in receiving fm broadcast wave
Inventor: HIROHASHI KAZUTOSHI
IPC: H03G3/34
Filed: 1983-03-26
Abstract: PURPOSE:To reduce impulsive noise of a stereo demodulating signal by performing the sample holding operation and processing by means of a sampling pulse having a repetitive frequency in 38kHz in synchronizing with a pilot signal in an FM demodulation output. CONSTITUTION:An input audio signal is delayed 2 and inputted to a signal correcting circuit 5, and inputted to a control signal generating circuit CSG, and a control signal having a width corresponding to the period where impulsive noise included in the input signal exists is generated by the circuit CSG. A sampling pulse SP generating circuit PSG generates SPP4, P5 different from phase with each other by 180 deg. having the repetitive frequency in 38kHz in synchronizing with the pilot signal included in an FM demodulation output signal. An output signal S3 of the circuit 5 is inputted to a differentiation circuit 6A, where the signal S3 becomes a signal S7 by being subtracted with a signal S6 sampled and held SH by the P4, and the signal S7 becomes a signal S4' by being sampled and held SH by the P5. The signal S4' generates slope information of a desired signal during a period when pulse noise is produced at an SH circuit 7 and the information is inputted to the circuit 5 so as to reduce the impulsive noise.

Title: Electrophotographic printer
Inventor: TAKAHASHI KIYOSHI
IPC: B41J2/44
Filed: 1990-03-02
Abstract: PURPOSE:To set the extent of a printing area at a specified position on a paper by detecting the movement of the position of a paper in a direction vertical to a suction direction at the time of sucking the paper and moving the photosensitive area of a photosensitive drum in accordance with the detected displacement. CONSTITUTION:A paper position sensor 3 detects the displacement of the positions of both ends in a paper width which is vertical to the suction direction of the sucked paper from a reference position, and the detected value is transmitted to a mechanical control unit 2. When the unit 2 which receives data on the displacement of the position of the paper from the reference position transmits the data on a printed image to an exposure control part 4, it takes the moving amount of the paper from the reference position as a correction value, and the exposure control part 4 corrects the moving amount to be on the photosensitive drum and controls a light source so as to expose the printed image. Thus, the deviation of a printing position in an absolute position from the end of the paper is prevented in the printed result.

Title: Method for detecting minute signal voltage
Inventor: SHIBATA SHINTARO
IPC: G11C11/34
Filed: 1988-03-04
Abstract: PURPOSE:To reduce power consumption in a minute signal voltage detecting circuit by controlling switches based on the signal of an external input address and supplying the charge of the minute signal voltage detecting circuit only to a memory cell when writing is executed to the memory cell. CONSTITUTION:A control clock signal generating circuit 4 is operated based on an external input X address or the signal equivalent to the address, and a switch group S (p, r) (p=1...P) at a side to which a selected memory cell is connected is switched to a conductive state. In a memory cell selected state, one switch group S (p, 2) (p=1...P) becomes the conductive state, and another switch group S (p, 1) (p=1...P) maintains a non-conductive state. At this time, since the output voltage of a minute signal voltage detecting circuit SA (p) is impressed through a bit line BL (p, 2) to each selected memory cell M (p, 2), charge quantity corresponding to stored data is set to a capacitor Cs in the memory cell. Thus, the power consumption in the minute signal voltage detecting circuit SA (p) can be reduced.

Title: Circuit protective device
Inventor: TAKAHASHI EIZO
IPC: H01M2/10
Filed: 1993-03-11
Abstract: PURPOSE:To operate to an abnormal condition of a circuit effectively even though a power source whose output characteristics has a change with the lapse of time is used, so as to reduce energy loss of a battery, by composing a battery terminal with a material having a mechanical deformation by the temperature variation. CONSTITUTION:At a normal temperature, a reverse connection preventive mechanism 1 presents a bellows form in the form to avoid the projection of the positive electrode of a battery 2, and the projection contacts to the positive electrode 7 of a battery box 3 so as to connect with a circuit. Therefore, in the normal condition of the circuit, an apparatus generates no error operation even though it is used at the maximum temperature in the scope of its operating temperature. When the battery generating an abnormal condition in the circuit becomes to an overload and is heated, the heat is transmitted to the mechanism 1, and the bellows is extended at a specific temperature or higher, so as to separate the projection of the battery 2 from the positive electrode 7, and the circuit can be cut off. Consequently, even though a power source having a variation of short circuit current value by the remaining capacity of the battery, such as the first battery, is used, it operates within a temperature scope safe to a human body, and the capacity of the battery is never hurt.

Title: Cryostat
Inventor: IWAMOTO TOSHIO
IPC: H01L39/04
Filed: 1981-04-07
Abstract: PURPOSE:To decrease ring currents flowing through an inner vessel made of a metal by mounting a metallic cylinder having conductivity equal to or higher than copper in the vicinity of the inner wall of the inner vessel encasing a superconductive coil. CONSTITUTION:The metallic cylinder 11 having conductivity equal to or higher than copper is set up in the vicinity of the inner wall of the inner vessel 2 made of the metal encasing the superconductive coil 1 so as to surround the coil 1. The resistivity of copper at the temperature of liquid helium is smaller than that at the same temperature of stainless steel as the principal forming member of the inner vessel 2 by apporoximately figures. Accordingly, a calorification rate is extremely small even when the ring eddy currents flow through the cylinder 11 similarly. Since the direction of the change of currents flowing through the coil 1 and the direction of the change of currents flowing through the cylinder 11 are directed oppositely, voltage induced to the inner vessel 2 due to the changes of these currents mutually denies and drops. That is, since the value of the ring  eddy currents flowing through the inner vessel 2 is also reduced, calorific value  is decreased.
