Title: Noise decreasing device
Inventor: SASAKI TORU
IPC: H04R3/00
Filed: 1989-03-29
Abstract: PURPOSE:To suitably reduce an external noise by supplying the external noise collected by means of a microphone through a characteristic transmission means to a sounding means, decreasing the noise from the outside to an ear, and controlling the characteristic transmission means according to noise levels. CONSTITUTION:A control circuit 3 controls an output signal from a microphone 2 so as to invert a phase based on a frequency characteristic. An output signal from the control circuit 3 is inputted to a variable gain amplifying circuit 4. To the variable gain amplifying circuit 4, a control signal, which detects the level of the external noise outputted from the microphone 2 and outputs the signal according to the noise level, from a gain control circuit 9 is inputted. That is, the gain control circuit 9 outputs the control signal which enlarges the gain (amplitude degree) of the variable gain amplifying circuit 4 when the detected noise level is large and reduces the gain of the variable gain amplifying circuit 4 when the noise level is small. By the gain control circuit 4 and the characteristic transmission means 5, the noise reduction conforming to the level of the external noise is realized.

Abstract: PROBLEM TO BE SOLVED: To enable generation of low melting point metal material ions stably over a long period of time by leading the ions generated by sputtering a material plate containing an ion generation element retained at an inner wall surface of a box-like vessel by means of the plasma generated by the gas led into the vessel, out of the vessel, and holding a generated liquid. SOLUTION: A material plate 29 mounted demountably in a slit 31 of an inner wall of an arc chamber 21 of an ion source chamber of a Burnus type is subjected to sputtering of Ar gas by the plasma generated by thermoelectron from a filament to thereby generate ions which are led out from a drawing outlet 23. Only In ions in the ions from the material 29 of high melting point InSb monocrystal type is implanted into a sample after they are separated by a separation electromagnet. The In made excessive by evaporation of Sb having a high evaporation Te is melted and flows to a lower inclination 31B of the slit 31 passing through a through hole 31D from an upper inclination 31A of the slit 31. Since the filament is not close to an opposite electrode 24, no abnormal electric discharge is generated.

IPC: B41J29/46
Filed: 1987-03-27
Abstract: PURPOSE:To facilitate automatic inspection of printer, by providing an inspection means for detecting condition of the printer based on an inspection instructing signal fed from an I/O means and outputting the inspected signal to the I/O means and connecting the printer with an external computor. CONSTITUTION:When a host computor 2 outputs a data request command, a printer 4 outputs a command reception finish signal through an I/O port 14. The host computor 2 receives the signal and sends a signal for requesting a detection signal from a sensor 24 to the printer 4 which converts the detection signal into serial data and sends the serial data on a status line 34 to the host computor 2. The host computor 2 converts the serial data into parallel data which are transmitted on a data line 30 back to the printer 4. The printer 4 compares the returned data with an original data, and sends an output representing successful transfer to the host computor 2 if transfer is carried out well.

Title: Signal level detection circuit
Inventor: SANO KOICHI
IPC: G01R19/165
Filed: 1985-04-10
Abstract: PURPOSE:To prevent malfunctioning due to frequency components below a specified frequency and noises in the detection of frequency components above the specified frequency, by counting the output frequency above the set value to clear it by a specified method. CONSTITUTION:A signal generated from a signal generation source 1 is extracted in terms of frequency components above a specified frequency with a bypass filter 2, compared with a set level with a level setting circuit 3 by a comparator circuit 4 and when the level is exceeded, an output VC is produced. The output VC is counted with a counter circuit 7 and when the counts value coincides with the value set with a counts value setting circuit 6, the detection signal is produced from the circuit 7, which is cleared periodically by a clear signal, the cycle of which is set for a value obtained by multiplying the cycle of the specified frequency as provided from a counting clearing circuit. Thus, malfunctioning due to frequency components below the specified frequency and noises can be prevented.

Title: Active twin t-type filter
Inventor: OKANO YOSHIHIRO
IPC: H03H11/12
Filed: 1985-04-10
Abstract: PURPOSE:To obtain damping quantities by means of both of a pole frequency and zero-point frequency, by setting the resistance value of a feedback circuit containing a resistance type potential dividing circuit in such a way that the pole frequency and zero-point frequency can be separated from each other. CONSTITUTION:One end of a resistance R6 is connected with the connecting point of the inversional input terminal and output terminal of an operational amplifier A2 and the other end is connected to the connecting point of another resistance R3 and capacitor C3. The transfer function F(s) of this filter is expressed with the formula. The gamma of the formula corresponds to a pole frequency and the alpha corresponds to a zero-point frequency. When a relation, gamma>alpha, is established between the gamma and alpha, a relation, omega0<beta, can be obtained and a damping quantity by means of a secondary pole frequency omega0 having an optical Q can be obtained. When the alpha and beta are set to have a relation, alpha>>beta, the influence of the zero-point frequency alpha can be removed by means of a simple primary filter, since the influence occurs at higher frequencies. Therefore, a large damping quantity can be obtained in the vicinity of a zero-point frequency beta.

Title: Electrophotographic printer
Inventor: MIYAZAWA YOSHINORI
IPC: B41J2/455
Filed: 1990-03-26
Abstract: PURPOSE:To obtain a high resolution with a large exposure width by providing such a light-emitting surface whose curvature is maximum at an optical axis part and becomes smaller as it is apart therefrom when the curvature is positive where it is convex faced toward the photosensitive body of an image-forming optical system. CONSTITUTION:A light 46 emitted from a LED element 45 is emitted as a light 47 from the image-forming lens 43. Since an image-forming lens 44 has an incident surface 48 intersected orthogonally with the optical axis 51, the light 47 advances straightly and enters into the correcting lens 44. The light emitting surface 49 of the correcting lens 44 is convex facing to the image-forming surface of a photosensitive drum 1. When the curvature of the light emitting surface 46 is positive where it is convex and negative where it is concave, the curvature is the positive maximum curvature on the optical axis 51, becomes smaller as it is apart therefrom, and is negative at a peripheral part. Hence, the image is formed at a point close to the light-emitting surface 46 in the vicinity of the optical axis 51 and formed at a point apart from the light-emitting surface 46 at a part apart from the optical axis 51. Consequently, the well focused image of a LED element string can be formed on a cylindrical surface. Thus, the high resolution can be obtained with a large exposure width.

Title: Reverse charge preventing unit for distributed power supply
IPC: H02J3/38
Filed: 1992-03-31
Abstract: PURPOSE:To obtain an inexpensive reverse charge preventing unit for distributed power supply by a constitution wherein ON/OFF state of a circuit breaker is detected based on presence/absence of high frequency signal superposed on a distribution line. CONSTITUTION:High frequency detectors 12a, 12B disposed on the distributed power supply 10a, 10b side make a decision whether a high frequency signal is present on a distribution line 5. Since no high frequency signal is superposed on the circuits subsequent to a distribution line 3 upon opening of a circuit breaker 2, the high frequency signal detectors 12a, 12B make a decision that the circuit breaker 2 is opened and then open switches 11a, 11b immediately. The switches 11a, 11b can be thrown in when the high frequency detectors 12a, 12b detect a high frequency signal on the distribution line 5 or a voltage being applied on the distribution line 5. According to the constitution, distributed power supply is disconnected quickly from the system and reverse charging is prevented.
