Patent JP-H07274264-A (JP)
Title: Electric device
Inventor: YAGI KENJI
IPC: H04Q9/00
Filed: 1994-03-31
Abstract: PURPOSE:To recognize the operating state of the device main body even when the user do not approach a main body display section by using a transmission circuit provided to the device main body so as to send a signal representing the operating state of the device main body to a remote control transmitter and displaying the signal onto a display section provided to the remote control transmitter. CONSTITUTION:For example, when various switches 5 of a base upper side 4a of a device main body 1 being an electric fan are operated or a receiver 8 receives a control signal from a remote transmitter 7, a microcomputer of the main body 1 sets on/off, wind flow, timer, rhythm or the like of a fan motor 11, and displays the setting content to an LED display section 6A. When a signal requesting the setting content is sent from the remote control transmitter 7, a transmitter 9 provided to the main body 1 returns an operation state signal to the remote control transmitter 7. Then the receiver provided to the remote control transmitter 7 receives the operation state signal and it is displayed on an LED display section 15A of the remote control transmitter 7. Thus, the operating state of the main body 1 is recognized remotely.

After annealing, the SiN film is eliminated. Thereby, the uniformity of treatment is improved, the characteristics of a semiconductor integrated circuit is increased, and the manufacturing yield is improved.

Title: Circulation driving type rate gyro
Inventor: YAMAGUCHI HIROSHI
IPC: G01C19/56
Filed: 1986-04-11
Abstract: PURPOSE:To separate a component corresponding to a Coliolis force and a component corresponding to a disturbing inertial force with high accuracy by weighting and adding deviation detection signals obtained by detecting independently forces operating on a couple of mass elements which are driven symmetrically. CONSTITUTION:The piezoelectric elements 1a and 1b are driven cyclically in the opposite directions to make the Coliolis force operate, and detect the forces operating on them to generate the deviation detection signals 1a' and 1b'. The signals 1a' and 1b' contain components corresponding to inertial forces, disturbing inertial forces, etc., accompanying the driving. Preamplifiers 2a and 2b convert the signals 1a' and 1b' into low-impedance voltage signals 2a' and 2b'. An adder 4 weight and adds the signals 2a' and 2b'. A signal processing circuit 3 extracts and processes the component corresponding to the Coliolis force from the output signal of the adder 4 to generate an output proportional to an input angular velocity. Thus, the sensitivity variance of the elements 1a and 1b is compensated by the adder to compose the differential response between operating forces to both elements equally, thereby canceling the components corresponding to the disturbing inertial forces almost completely.

Filed: 1990-04-02
Abstract: PURPOSE:To obtain an excellent S/N ratio and to improve receiving specific sensitivity by always detecting the output amplitude of a preamplifier, negatively feedback controlling a cathode voltage to be applied to an APD so as not to become a predetermined value or higher, detecting the output amplitude of a gain variable amplifier, and negatively feedback controlling a gain so as to become a constant value. CONSTITUTION:If an optical input level is low and the output amplitude of a preamplifier 2 is less the allowable maximum input amplitude of a gain variable amplifier 3. The amplification factor of an APD 1 is fixed to a value in which its S/N ratio becomes maximum. If the level is high, the cathode voltage of the APD 1 is negatively feedback controlled so that the output amplitude of the preamplifier 2 is fixed to the allowable maximum input amplitude of the amplifier 3. On the other hand, a second negative feedback loop is formed of the amplifier 3 and a gain controller 5, and the gain of the amplifier 3 is controlled so that the output amplitude of the amplifier 3 becomes constant. That is, if the level is low, only the gain of the amplifier 3 is controlled, while if the level is high, only the amplification factor of the APD 1 is controlled.
