IPC: H04N5/225
Filed: 1992-08-04
Abstract: PURPOSE:To surely cancel and remove a noise component generated from a motor contained in a voice signal. CONSTITUTION:The voice signals collected by a microphone 111 are sent to an adder circuit 113 after they are amplified. Corresponding to an autofocus(AF) state, a microcomputer 121 drives a stepping motor 117 through a pulse generator 119 and driver 118 and controls an AF unit 116 in a focused state. At such a time, a noise cancel signal is generated corresponding to a pulse for driving the stepping motor, and the level and phase of the noise cancel signal are respectively corrected by correction circuits 125 and 126 and sent to the adder circuit 113 while using level correction data and phase correction data read from memories 122 and 123 corresponding to the speed of the motor 117. Thus, the noise component of the voice signals is canceled by the adder circuit 113, and those signals are outputted.

Title: Level adjusting circuit
Inventor: SAITOU HISAMI
IPC: H03G3/10
Filed: 1988-08-24
Abstract: PURPOSE:To simplify a circuit by suppling an input signal from a front step circuit to the base of a first transistor to constitute a differential amplifier and dividing the input signal by a resistance, a variable resistance and a capacitor and supplying it to the base of a second transistor. CONSTITUTION:To a second transistor Q3, the output of a front step circuit is divided by a resistance R11, a variable resistance VR2 and a capacitor C2 and inputted. When the frequency of the output of the front step circuit is sufficiently high, the impedance of a capacitor C2 becomes approximately 0, and from the collector of the second transistor Q3, the output of the level based on the resistance value of the resistance R11 and the variable resistance VR2 is obtained. On the other hand, since the impedance of the capacitor C2 is sufficiently large for the direct current component of the output of the front step circuit, the level of the base of first and second transistors Q2 and Q3 becomes the same, and the output for the direct current component does not appear at the collector of the second transistor Q3. Thus, the level adjustment can be executed, the number of terminals is one terminal, it is not necessary to supply the bias, and therefore, the circuit can be made into the simple constitution.

Title: Method and apparatus for preventing vehicle from rear end collision
Inventor: TANAKA IWAO
IPC: B60Q1/44
Filed: 1982-11-26
Abstract: PURPOSE:To evoke attention of a succeeding vehicle for preventing rear end collision by lighting an alarm lamp in braking so that the alarm lamp self-holds the lighting condition only for a predetermined time after releasing a braking means from its operation. CONSTITUTION:In braking operation, brake switch 1 and a switch 13 are turned on to energize a relay 2. Respective contacts 3-5 are changed over to light a stop lamp 6 through a lighting circuit L4. Also, when the switch 13 is turned on, current does not flow through a capacitor 12 and a control circuit L1. When a brake is released, the respective switches 1, 13 are turned off. Then, since the return of the contact 3 is slightly delayed, current is supplied to the capacitor 12 and the control circuit L1 so that the relay 2 holds itself. Since current is not supplied to the control circuit L1 by the completion of charging the capacitor 12, the relay 2 is released from the self-holding to turn off the lamp 6. Also, in pedalling an accelerator pedal, since an accelerator switch 10 is turned off, the relay 2 is released from the self-holding to turn off the lamp 6.

IPC: G03F9/00
Filed: 1984-10-05
Abstract: PURPOSE:To obtain a reflected image, by which a specified pattern can be readily identified from other parts, by limiting the wavelength of a bright field lighting in a specified wavelength region in order to identify an aluminum wiring pattern and a layer beneath the pattern clearly. CONSTITUTION:A dark-field lighting device is composed of a dark field lamp 3 and parabolic concave mirrors 11 and 12. The light is projected to the light axis of an objective lens 2 from the slant direction. A bright-field lighting device is composed of a bright field lamp 4, a condenser lens 8, a field lens 9, a wavelength control filter 10, a half mirror 5 and a reflecting mirror 7. The light beams from both devices are applied on a wafer 1 simultaneously. The wavelength control filter 10 selects the light in the wavelength so that only the light, by which the reflectivity of patterns other than an aluminum pattern become small, can be projected on the surface of a wafer. Thus the aluminum pattern formed on the wafer 1 is identified from the other patterns clearly. Therefore, the aluminum pattern, which has been difficult to identify, can be definitely identified.

Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To effectively perform the deodorizing treatment of exhaust gas even if moisture or an oil component is contained in the exhaust gas and to prevent the damage of the adsorbing capacity of malodor molecules caused by the moisture or oil component. SOLUTION: An oil component and moisture in the exhaust gas discharged from a exhaust gas generating source 1 such as a garbage dryer or the like are removed by a condenser unit 2 to be discharged as condensed water 21 from a drain piping A14. The exhaust gas 8 from which the oil component and moisture are removed is supplied to an adsorbing tower 3 packed with an adsorbent 7 partially containing ceramic and malodor molecules are adsorbed and removed from the exhaust gas 8 by the adsorbent 7. The exhaust gas 9 thus deodorized is discharged to the open air as odorless exhaust gas 6 by a blower 4. The condensed water formed in the adsorbing tower 3 is accumulated on an inclined plate 16 to be discharged as dew condensation water 17. Therefore, the deterioration of a malodor level and the lowering of deodorizing efficiency are prevented even in the adsorbing tower 3.

Title: Position detector
Inventor: OKUYA NORIO
IPC: G01D5/38
Filed: 1986-09-04
Abstract: PURPOSE:To achieve a higher accuracy, higher resolutions and a smaller size, by providing a Frensnel zone plate for detecting origin with a laser diodes as light source. CONSTITUTION:Light from a laser diode 11 is turned to an elliptical, parallel light with a collimator lens 12 to irradiate a mobile detection plate 13. A Fraunhofer's diffraction image passing through a slit 16 is projected onto a fixed slit plate 14 in which numerous slits 18 are arranged in parallel with the distance therebetween coinciding with the distance of the principal maximum of the diffraction image. A light transmitting through a slit 18 is detected with a photo detection element 15a of a photodetector 15. On the other hand, as a light irradiates a Frensnel zone plate 17 of the detection plate 13 from the laser diode 11, it is focused on the slit plate 14 and the position of origin is detected with the photo detection element 15b. This allows the irradiation of a photodetector with a narrow luminous flux with a high output thereby achieving a higher accuracy, higher resolutions and a smaller size.

Title: Method and apparatus for measuring optical film thickness
Inventor: HIROSE HIDEO
IPC: G01B11/06
Filed: 1990-08-06
Abstract: PURPOSE:To make the apparatus compact with a simple constitution and to obtain the method and the apparatus for measuring the optical film thickness by which the measuring range of the entire apparatus can be expanded by providing the constitution wherein a lambda/4 plate 3 is fixed so that the optical axis is set at 45 deg. with respect to the incident surface, and a polarizer can be rotated. CONSTITUTION:The luminous flux which is emitted from a light source 1 is made to be the linearly polarized light through a polarizer 2 and cast into a lambda/4 plate. The lambda/4 plate 3 is fixed so that the optical axis is set at 45 deg. with respect to the incident surface. The polarizer 2 can be rotated around the optical axis. The polarizer 2 and the lambda/4 plate 3 can be set so that the polarized light can be converted into the polarized light having the arbitrary phase difference with the bearing of the linear polarized incident light on the lambda/4 plate 3 based on the well known principle of the Senarmont compensator. When the luminous flux is reflected from a sample 4 having the very thin film on the surface, the phase difference DELTA is generated between the P component and the S component. Since the DELTA is the function of only the bearing thetaof the polarizer 2, the delta is obtained from the bearing theta directly, and the thickness of the film can be computed.
