Title: Image reproducing and outputting device
Inventor: KASUYA YUKIO
IPC: G03G15/04
Filed: 1983-02-28
Abstract: PURPOSE:To attain the effective time untilization of an electrophotographic copying machine which stores a measured value of original density and controls copying condition to obtain proper copying density, by resetting the stored value in preparatory motion for an original scan or preparatory rotation of a photosensitive drum. CONSTITUTION:Optical systems 21, 24, and 25 move forth up to an inversion position 22B and then start moving back. The potential of a latent image obtained by projecting an original image upon the photosensitive drum 33 is measured by a sensor 49 and integrated with time to know the original density value. The brightness of an original lighting lamp is controlled on the basis of this value. The drum is switched between fast rotation and slow rotation according to an unmagnification and an enlarged/reduced copy, so the integral time is varied depending upon a selection. Limiters for an upper and a lower limit value of the integral value are provided to handle an abnormally dence or light original.

Title: Method of constructing heat accumulating chamber
Inventor: KIDO NOBUYUKI
IPC: F28F23/00
Filed: 1979-03-23
Abstract: PURPOSE: To increase thermal efficiency, by superposing heat accumulating bricks, each having a turbulence promoting section projected in a plane perpendicular to the gas flow, in the manner that they are extended in the direction of gas flow and the gas flow is twisted in a helical form by the turbulence promoting sections.  
     CONSTITUTION: Brick 1 is composed of main body 2 shaped substantially in a cross form and a turbulence promoting section 3. The turbulence promoting section 3 is extended from at least one of legs 4 of the cross-shaped main body 2 in a plane perpendicular to gas flow. Gas passages 5 are formed between legs 4 of adjuacent bricks 1 having the same shape. These bricks 1 are superposed on each other such that their positions are not displaced in vertical direction but twisted toward upper stages. By such an arrangement, gas flow can be controlled to be helical, which is effective in promoting heat transfer by turbulence, prolonging the time when gas stays in gas passage 5, and suppressing development of turbulent boundary layers.

Abstract: PURPOSE:To prevent linearly polarized light from going to elliptic due to double refraction of a substrate and increase C/N by providing a phase difference compensating film in a lens of an optical system that converges and irradiates light on a recording medium and receives returning light by a light detector. CONSTITUTION:Luminous flux that passed a beam splitter 37 is condensed by an objective lens 38 and irradiated on a photomagnetic disk 33. Returning light reflected by a recording layer 42 passed through the objective lens 38 and apart of it is reflected by the beam splitter 37, and passes through an analyzer 43 and received by a light detector 44. Phase difference is formed as below between S polarization and P polarization due to double refraction in going and returning path that transmits a disk substrate 41, and a beam that includes the two polarization components is made to elliptic, and accordingly, a film 51 that eliminates phase difference is provided in the objective lens 38. Thus, no phase difference is formed in luminous flux that passes on the optic axis and linearly polarized light is prevented from becoming elliptic due to double refraction of the substrate, and C/N can be increased.

Abstract: PURPOSE: To improve reproduced pictures and to prevent pictures and sounds from deteriorating even after reproduction by recording video and sound signals on the same track in the 'VHS(R)' system and executing digital processing. CONSTITUTION: In the recording and reproducing system of U-VTR, a machine part for driving a head drum 90 adopts a machinery part of an existing 1/2 inch VHS system as it is, that is provided with a recording system of 2 channels and 4 heads. Rate of recording data is 20 Mbps per channel; since a recording high frequency is 10 MHz and a high frequency recording at the relative speed like VHS system is impossible, the system rotates the drum 90 at speed of 3600 rpm. Thus, the system gains the relative speed of the drum 90 far more than VHS system, enables recording and reproducing up to high frequency of 10 MHz and makes running effective lead angles of a tape 95 5952 deg.. That is, the recording density becomes 1.7 bit per 1 μm and the recording area per bit is only approximately 8.4 μm.
