Title: Image forming device
Inventor: TAKAHASHI MASAKI
IPC: G03G15/00
Filed: 1988-03-30
Abstract: PURPOSE:To prevent the deviation of an image in case of multiple copying to be caused by contraction and deviation in position of a material to be transferred by detecting the size of the material to be transferred and the relative position of the material to be transferred to an original image before transferring the original image on the material to be transferred and controlling the transfer magnification and the transferring position of the original image based on the detected result. CONSTITUTION:Pulse counting circuits 49a and 49b count output pulses from a part where light is not shielded with paper 29 on CCD sensors 33a and 33b and a computation circuit 51 computes the pulses of both pulse counting circuits 49a and 49b. Therefore, the width of the paper 29 can be detected and also a difference between the center position of the paper 29 and the center position of two CCD sensors 33a and 33b, that is, the displacement of the paper 29 from a photosensitive drum 27 can be obtained. The transfer magnification and the transfer position of the original image to be transferred on the paper 29 can be computed and the transfer magnification and the transfer position obtained thus are stored in a storage device 47. By moving a lens 21, etc., the copying magnification and the copying position can be corrected.

Title: Code quantity estimating device
Inventor: ABE SHUJI
IPC: H03M7/30
Filed: 1993-03-31
Abstract: PURPOSE:To correctly estimate a code quantity. CONSTITUTION:Quantizers 31-34 quantize an orthogonal transformation coefficient with quantization widths Q1-Q4 and store the results in a memory 35. The memory 35 stores those quantization outputs in addresses indicated by the respective orthogonal transformation coefficients and the quantization widths. A quantization coefficient calling device 36 specified addresses of the memory 35 on the basis of a quantization table which shows the constitution of the quantization means with the bands of the orthogonal transformation coefficients and the quantization widths. Consequently, the same quantization outputs as those when the quantization means performs quantization are obtained from the quantization coefficient caller 36. A data amount calculator 38 finds the code quantity from the output of the quantization coefficient calling device 36 and accurately estimates the code quantity.

Title: Power circuit
Inventor: ICHIJIMA DAIJI
IPC: H02J1/02
Filed: 1989-03-29
Abstract: PURPOSE:To smooth an output signal, to stabilize output voltage and to reduce the ripple by load fluctuation despite the frequency fluctuation of a load by connecting a circuit having a higher input impedance as compared with an output impedance. CONSTITUTION:To output terminals 4 and 6 is connected an emitter-follower circuit 11 very high in an input impedance and very low in an output impedance. The emitter-follower circuit 11 is composed of a transistor Q2 and a bias voltage source Vb1. The signal current from a load circuit 10 flows in the direction as shown by an arrow at all times and will not flow from a common output terminal 5 to an earth terminal 7 despite the frequency fluctuation of the load circuit 10. The output voltage can thereby be stabilized and a low output impedance obtained.

Title: Optical thermometer
Inventor: MURATA HIROAKI
IPC: G01J5/38
Filed: 1985-04-08
Abstract: PURPOSE:To make stable and high-precision measurement possible by setting the signal light of the first light emitting element and the reference light of the second light emitting element so that the difference of center wavelength between them is 10-200nm. CONSTITUTION:The first light emitter 2 has the first light emitting element 4 which radiates the signal light of about 0.88mum center wavelength and the second light emitter 6 has the second light emitting elements 8 which radiates the reference light having about 0.95mum center wavelength. Consequently, the difference of center wavelength between the signal light and the reference light radiated from both elements 4 and 8 is about 70nm. The signal light and the reference light are multiplexed by a means 10. In this case, components having wavelengths lower than the center wavelength of the reference light are cut by an optical filter 12. The multiplexed light is irradiated to the temperature sensing element 16 of a temperature sensor 14. Since the range of wavelength of the reference light is wider than the variance range of the optical fundamental absorption end of the element 16, it is not absorbed by the element 16 but passes through it. Meanwhile, the signal light is absorbed in accordance with the variance of temperature of the element 16. Thus, influences of bending loss, etc. are reduced to make high-precision measurement possible.

Filed: 1978-06-20
Abstract: PURPOSE:To operate the transistor always at best cindition, which is operated as a mixer in case of VHF reception and is operated as IF amplifier at UHF reception, by providing diode. CONSTITUTION:At VHF reception, the selector switch S is selected to a position, and the television signal from the terminal 1 is inputted to TR11 in which the transistor TR11 is set at efficient operating point as a mixer consisting of the resistors 16,17 and the emitter resistor.
