Title: Agc circuit
Inventor: OOHASHI TAMAKI
IPC: H03G3/18
Filed: 1983-07-27
Abstract: PURPOSE:To obtain an AGC circuit with excellent attenuation efficiency by using a push-pull amplifier circuit from which an output signal with less distortion and large amplitude is obtained. CONSTITUTION:A bias voltage is impressed to each base of a couple of transistors (TR) 6a, 6b, each emitter is grounded via a common impedance circuit 10, a primary coil 11a of an induction coupling circuit 11 is connected between collectors, and an AGC voltage is impressed to the emitter of each TR in a way that the collector current is decreased as an input signal increases. Since the operation is conducted between the TRs 6a, 6b at each half cycle of the input signal, the attenuation of the signal produced in the coil 11a is increased depending on the amplitude of the input signal and the self-attenuating operation is conducted. Further, the base potential of the TRs 6a, 6b is varied by impressing an AGC voltage decreased as the increase of the input signal to a midpoint (A) of the coil 2b. Then the collector current is increased while the input signal is weak and the output signal is attenuated when the input signal is strong. Thus, a large attenuation is obtained through said attenuation together with the self-attenuation.

Title: Image forming device
Inventor: YAGISHITA TAKAHIRO
IPC: H04N1/21
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To obtain a formed image with high image quality by adopting the configuration of losing data with a lower weight only in the case of dividing image data, providing weighting to the divided image data so as to form the image even when a data amount supplied to a write means is reduced. SOLUTION: Page description data fed from a host device 2 are given to an RIP section 3, in which the data are converted into bit map data, and the resulting data are divided by a division section 4. The division section 4 divides the bit map data into data important visually and data not important. The divided data are compressed by a compression section 5 by an optional method and stored in a storage section 6. When the print data by one page are stored in the storage section 6, the data are read and the read data are expanded by an expansion means 7. The print data are written in a photo sensing body by two laser diodes of a write section 8 based on the expanded data. Since the data with low weighting are not companded, a high processing speed is obtained.

Filed: 1990-05-25
Abstract: PURPOSE:To reduce the occurrences of detecting errors by directing a wavefront converting element to the surface of a first object, emitting a plurality of luminous fluxes having the different wavelength components on the element, and utilizing the luminous fluxes which are deflected with the wavefront converting element. CONSTITUTION:A semiconductor laser LD is used as a light source. Luminous flux 1 (central wavelength lambda=830 nm) is emitted from the light source LD vertically on a point A on the surface of a first Fresnel zone plate 4 on the surface of a mask 2 within a plane that is in parallel with the surface of the paper. The reflected light from a wafer 3 is cast on a point D (E) on the surface of a second FZP plane 5 on the surface of a first object 2. The second FZP 5 has the optical action by which the emitting angle of the emitting diffraction light is changed in correspondence with the incident position of the incident luminous flux. The diffracted lights (61 and 62) of specified orders which are diffracted at an angle theta2 from the second FZP 5 are guided on the surface of a light receiving means 8 through a condenser lens 7. The interval between the mask 2 and a wafer 3 is operated and obtained by using the positions of the centers of gravity of the incident luminous fluxes (61 and 62) at the surface of the light emitting means 8.

Title: Pattern recognizing device
Inventor: NATORI NAOKI
IPC: G06F15/18
Filed: 1995-05-12
Abstract: PURPOSE: To attain more accurate pattern recognize by detecting the partial area of a character pattern, storing the detected area and acquiring a feedback rule for rerecognizing the character pattern when a recognized result obtained from an output part is not determinate, and when a succeeding recognized result is not determinate, executing rerecognition by using the feedback rule. CONSTITUTION: A character pattern or a picture pattern inputted to an input part 1 is learned and an unleaned character pattern or picture pattern is sorted by an intermediate part 2. The intermediate part 2 summarizes information to be outputted and an output part 3 outputs a final recognized result. When the outputted recognized result is not determinate, a feedback control part 41 in a feedback part 4 detects the partial area of the character pattern and stores the detected area in a feedback data base 42. A feedback rule corresponding to the partial area is acquired by storing the area, and when a succeeding recognized result is not determinate, rerecognition is executed by using the feedback rule. Thereby more accurate recognition can be attained.

Title: Positioning control device for main shaft driving motor
Inventor: UNNO MASATO
IPC: G05D3/00
Filed: 1985-06-24
Abstract: PURPOSE:To omit the replacing work of a detector even if the rotational direction of a motor is changed by changing an electrical signal to be applied to an I/O port by a reading condition setter to change data to the I/O port and to change processing in a CPU. CONSTITUTION:When the rotational direction of a rotary body coincides with the polarity of an MS signal 9 corresponding to an angle and a position error command enters an effective range, a command value F(theta) starts from F, approaches F/2 in accordance with the advancement of rotation and stops at an objective point F/2. When the rotational direction does not coincide with the signal 9 and is reversed, the command value F(theta) starts from '0', so that F(theta)<0 is formed and the rotary body driven to the objective point by the 2nd speed command value is driven in the reverse direction, generates vibration and is not converged. In this case, relating data to the I/O port 45 are changed by a reading condition setting circuit 44. Since the data of the I/O port 45 are changed at the input of the signal 9 to the CPU 41, the minimum value Amin is reread as -Amin and the succeeding signal 9 is continuously processed while being inverted at its polarity. Thus, the rotary body is stopped.

Abstract: PURPOSE:To eliminate a useless operation of a protective device by receiving an operating contact circuit of the device by a time limiting relay, conducting the relay by the operation of the device, and shutting OFF an operation instructing circuit, after a settled time is elapsed, by the relay. CONSTITUTION:An auxiliary relay X is excited under a condition that a protective device circuit 1 is fully closed by an operation switch ON, and the relay X is self-held. An electromagnetic contactor 52C for a compressor motor is excited under a condition that a temperature regulator 23C is closed, and a compressor is operated.

Then, the excitation of the contactor 52C is also deenergized, and a compressor is stopped. Such a time limiting mechanism is associated thereby to prevent stop of a refrigerator due to a useless operation of the device.
