Title: Foreign matter inspection device
Inventor: HAYANO FUMITOMO
IPC: G03F1/84
Filed: 1987-01-29
Abstract: PURPOSE:To decide a surface where foreign matter sticks excellently by projecting light in different directions and comparing the quantities of scattered light from the foreign matter in respective cases. CONSTITUTION:Light sources 10 and 14 are so arranged as to project light on a thin film 1 at different angles of incidence. For example, light from the light source 10 is for oblique illumination (at a relatively small angle to the surface of the thin film 1) and light from the light source 14 is for downward illumination (at a relatively large angle to the thin film 1). The quantities of illumination light beams incident on the thin film 1 are adjusted previously by filters 12 and 16 for light quantity adjustment so that the quantities of scattered light from the foreign matter sticking on the top surface of the thin film 1, i.e. the levels of the photoelectric signals of a photoelectric detector 20 are equal between the oblique illumination and downward illumination as to the same foreign matter. Then scattered light beams from the foreign matter by the downward illumination and oblique illumination only are detected 20 and variation quantities of photoelectric signals at this time are compared to decide the surface where the foreign matter sticks.

Title: Remote control unit of camera
Inventor: BAN ITSUKI
IPC: H02P7/29
Filed: 1979-02-19
Abstract: PURPOSE: To obtain the remote control device of the camera by generating sound waves of relatively high frequencies from a sounding source and letting the actuator provided to an electromagnetic device make one reciprocation by way of these sound waves thereby operating the shutter of the camera.  
     CONSTITUTION: A release 13 and electrical circuits other than a light emitting device are contained in an electronic light  emitting device 7. The camera is held to a tripod and when the preparation for photographing is over, a whistle 32 is depressed, then the sound waves emitted by this become the output of a filter circuit 26a. When the whistle is sounded for more than 0.5sec, a motor 16 is supplied with current by the action of the current supply control circuit of the motor 16 and therefore the electromagnetic device operates and an actuator 14 makes one reciprocation and stops. Hence, the camera shutter pushbutton 12 is pushed and photographing may be cone.

Title: Photoelectric detecting device
Inventor: TANAKA TAKASHI
IPC: H03K17/78
Filed: 1990-01-26
Abstract: PURPOSE:To eliminate omission in detection caused by the mutual interference of photoelectric sensors and to adjust an optical axis by intercepting a light beam part which interferes in the light receiving device of other photoelectric sensor out of the light beams emitted from respective light sources with the aid of the non- transmitting area of a light beam control plate. CONSTITUTION:The light projecting devices 1a-1c are respectively opposed to the light receiving devices 2a-2c in the photoelectric sensor, and the light projecting devices are adjacently arranged on the same side as well as the light receiving devices. The light beam control plate 11 is arranged at a position distant from the light projecting devices 1a-1c and the light receiving devices 2a-2c so that it may separate them. The light beam control plate 11 is constituted of the non-transmitting area 111 and transmitting areas 112a-112c and only the light beams transmitted through the plate 11 out of the light beams 3a-3c emitted from the light projecting devices 1a-1c reach the light receiving devices 2a-2c respectively. Since the light beams 3a-3c are converged by the light beam control plate 11, it is only one light beam out of the light beams transmitted through the plate 11 that one light receiving device receives. Thus, the omission in detection caused by the mutual interference is eliminated and an object is surely detected.

Filed: 1994-02-14
Abstract: PURPOSE:To attain mixing signals of lots of sound resources located remotely to each other by multiplexing sound signals, an audio level control signal and an amplifier drive power supply voltage on a signal balanced transmission line. CONSTITUTION:Serial control data (sound level control information) 3S are given to a multiplexer/demultiplexer section 4, from which the resulting data are sent to a balanced cable 5. A multiplexer/demultiplexer section 6 of a controlled side extracts the data 3S and gives the data to a serial/parallel converter 7, which converts the data 3S into digital data for each channel and a D/A converter 8 converts the digital data into an analog voltage. Then the analog voltage is given to a mixer VCA 9 to control sound level. Finally the VCA 9 controls the sound volume of each microphone MIC and extracts a mixing sound signal 9S. The signal 9S is sent to the balanced cable 5 via the multiplexer/demultiplexer section 6, and the signal 9S is demultiplexer by the multiplexer/demultiplexer section 4 to provide an output of the signal 9S. Thus, a sound level is managed by the cable 5.

Title: Method for correcting unbalance of rotor
Inventor: IBE HIROMITSU
IPC: H02K15/16
Filed: 1993-02-04
Abstract: PURPOSE:To make it possible to efficiently correct balance of a rotor by correcting unbalance in order from the area of the rotor most prominent in unbalance. CONSTITUTION:An unbalance measuring section 16 measures magnitudes of unbalance on a commutation side and anti-commutator side, that is alpha and beta, and areas of that unbalance. Judging that a difference in unbalance (alpha-alpha0) is larger than a difference in unbalance (beta-beta0), and judging that the magnitude alphaof unbalance is larger than a measured value alpha0 on the commutator side, a computing section 17 calculates the amount of putty Pa to be adhered in response to the magnitude alpha of that unbalance, or the computing section 17 causes the putty Pa in this amount to be adhered to an armature 7 on the commutator side. Similarly, putty Pb is adhered to the armature 7 on the anti- commutator side. The unbalance is corrected in the same manner as previously mentioned until the magnitudes alpha and beta of unbalance are respectively reduced so as to be smaller than specified values alpha0 and beta0. Hence, for the unbalanced areas detected by the unbalance measuring section 16, the correction of unbalance having a larger magnitude is given priority.
