Title: Optical deflector
Inventor: OKAZAKI MASAHIDE
IPC: G02B27/28
Filed: 1994-06-07
Abstract: PURPOSE:To increase the efficiency of utilization of energy of a light beam while avoiding the effect of wobble and attaining stability at the time of high- speed rotation. CONSTITUTION:An optical deflector 7 is composed of an optical system 12 and a motor integrally rotating the optical system 12 around the axis L of a principal light ray of a light beam emitted from a semiconductor laser 3. The optical system 12 is provided with a polarized beam splitter(PBS) 10, a first and a second quarter wavelength plates 14, 16 stuck to two surfaces of the PBS10 and a first and a second reflection plates 18, 20. The semiconductor laser 3 emitting a light beam toward the PBS10 emits a linearly polarized light beam having a prescribed orientation. An incident light beam on the PBS10 is divided into the reflection and transmission directions by means of a polarizing film 10a in accordance with its orientation, passed through the first quarter wavelength plate 14, the optical path of the first reflection plate 18, the second quarter wavelength plate 16 and the second reflection plate 20, again reflected by or transmitted through the polarizing film 10a and projected toward the direction of an ftheta lens 9.

IPC: H04Q1/457
Filed: 1978-12-07
Abstract: PURPOSE:To shorten arithmetic word length by providing different discrete transform arithmetic circuits for multi-frequency signals and conduction test signals. CONSTITUTION:Discrete Fourier transform arithmetic circuit 11 is used only for multi-frequency signals, and discrete Fourier transform arithmetic circuit 12 for conduction test signals. Decision circuit 20 decides upon the presence of signals as to outputs of circuits 11 and 12. In this way, peripheral equipments are provided in common. Here, the arithmetic bit length of circuit 11 can be shortened matching with the relatively-small dynamic range, so that it will output the sum of the squares of a sine-wave component and cosine-wave component. On the other hand, the dynamic range of circuit 12 relatively large and the arithmetic bit length should be long on the square sum system, so that it will output the sum of absolute values of the sine-wave component and cosine-wave component. Consequently, two circuits 11 and 12 become nealy equal in output bit length and circuit 20 can also be constituted with adequate arithmetic bit length.

Title: Developing device
Inventor: NIMURA EIJI
IPC: G03G15/00
Filed: 1986-06-26
Abstract: PURPOSE:To exactly and easily change the gradation reproducibility of a developed image by setting the gradation reproducibility of a developed image density to an original image density, and changing a rotating speed of a developing roller in accordance with this gradation reproducibility. CONSTITUTION:The gradation reproducibility of a copy image obtained in accordance with an original image on an original platen 70 is set in advance by a picture quality setting device 47. A developing roller 44 is driven to rotate by an adjustable speed motor 45, and its rotating speed corresponds to the gradation reproducibility which has been set in advance by the setting device 47. That is to say, in case of setting a developed image to a hard tone, when the rotating speed of the roller 44 is set to a high speed, a supply toner adheres concentrically to a part where an electrostatic force is strong, of an electrostatic latent image, being a high density part of the original image. On the contrary, in case of setting the developed image to a soft tone, the rotating speed of the roller 44 is set to a low speed, and the toner adhesion quantity in the high density part of the original image is decreased. However, since the adhesion quantity in the low density part is scarcely varied, the reproducibility in the intermediate area is improved, and the gradation reproducibility of the developed image density to the original image density can be changed.

Abstract: PURPOSE: To decrease the input process exclusive time of the CPU at the key input time for the electronic desk computer by making the input buffer register (RFR) function as also the input/output BFR.  
     CONSTITUTION: The code of key 1 is received at input BFR2, and input buffer pointer 8 receives +8 every reception of the code at BFR2, and then the address is shown for the address of BFR2 to be taken in next at the key input time. Now if the switch control signal between input BFR2 and output BFR4 which is delivered from CPU3 indicates BFR4, AND gate 4 opens to send the contents of BFR4 to output device 5. At the same time, CPU3 detects the key input, and the control signal is sent so that device 5 is connected to BFR2 via control line 7. Thus AND gate 4A closes with gate 2A opened, and the contents of BFR2 is delivered to device 5. As a result, the exclusive time for the CPU's key the process of which is required with every key input can be decreased greatly.

Abstract: PURPOSE:A sugar source is brought into direct contact with super-heated steam at 120-300 deg.C, thereby it is heated under pressure and swollen to make free fatty acids and their oxidized contaminants vaporize away therefrom. CONSTITUTION:A sugar source for feed is put in a pressurized heater and brought into direct contact with super-heated steam 3-8kg/cm<2> pressure, then exposed to a low pressure such as normal pressure rapidly and swollen. The contact of the sugar source with super-heated steam allows free acids and their oxidized contaminants, which have adverse effects on the growth of domestic animals, to vaporize off, thus giving feed suitable for growing domestice animals.

Abstract: PURPOSE:To provide a light weight, excellent manufacturing properties by composing an outside member of a film having a specific linear expansion coefficient and adhered to an indoor wall through heat resistant adhesive and to reduce a manufacturing cost by eliminating expensive heat resisting glass plate. CONSTITUTION:An indoor lamp section structure 10 for a microwave oven has an outside member 11 which is formed of a film having a linear expansion coefficient of 3X10<-5>cm/cm/ deg.C or less and adhered to an indoor wall 13 through heat resistant adhesive.

Since the heat resistant adhesive and its film have excellent heat resistance, even if a temperature in the structure becomes high, heat shrinkage scarcely occurs, and yellowing deterioration of the member 11, floating from the wall 12, peeling, etc., can be prevented.

With such an arrangement, since the regions F are ineffective heat transfer regions where the heat exchanging efficiency is low, the total heat exchanging performance of the apparatus is not deteriorated substantially even if the heat transfer tubes in the regions F are replaced by the concentrated pipes 6, 6'. Therefore, it is enabled to save a corresponding length of the heat transfer tubes 7.
