IPC: C02F3/08
Filed: 1978-09-26
Abstract: PURPOSE: To achieve the improvement of treating efficiency and the simplification of maintenance by incorporating rotatable construction to the filter bed in the filter bed type foul water treating apparatus.  
     CONSTITUTION: The foul water 7 containing organic substances is introduced together with the circulating treated water being fed through a circulating pump 5 into a spray trough 3, from where it overflows and is evenly sprayed to the upper part of a filter bed 1. The liquid having been sprayed falls down while being stirred in the filter bed 1 under rotation by the operation of a drive motor 2, during which time the organic substances in the liquid make contact to the microbes on the surface of the filter bed 1 and the oxygen in air and are thereby oxidized.

IPC: G09G3/288
Filed: 1977-09-29
Abstract: PURPOSE: To make gas discharge at an intersection between both electrodes, by arranging a plural number of linear electrodes sandwiched between discharge gas media into a matrix shape.  
     CONSTITUTION: Row electrode Y 1  is applied with a scanning voltage, and column electrode X 1-1  is with an out-of-phase data voltage at the same time, so that the black-dot intersection will come on. Although X 1-2  is also applied with a voltage at this time, Y 5  is with no voltage, so that the white-dot intersection will not come on. In this way, driving is done by shorting between two column electrodes, so that one high-tension circuit and one buffer memory temporarily stored with data signals will be able to cover two column electrodes

Title: Code error detecting circuit
Inventor: HIDA NORIYUKI
IPC: H04L25/49
Filed: 1980-08-29
Abstract: PURPOSE:To simplify the circuit constitution of a code error detecting circuit for HDBn codes, by monitoring digital integral values of the HDBn codes by using a universal shift register. CONSTITUTION:The principal part of an error detecting circuit which detects errors of HDBn (High Density Bipolar n) codes used by a digital transmission system consists of two stages of universal shift registers and two AND gates 22 and 24. The  universal shift registers 20 are capable of transferring data to left and right and this operation is utilized to monitor digital integral values of HDBn codes. An HDBn  code free from a code error never has >=3 successive pulses of the same polarity, so  the largest digital integral value of the HDBn is 2 and when the digital integral  value exceeds two, the code is regarded as an error.

IPC: G03G15/00
Filed: 1990-05-08
Abstract: PURPOSE:To prolong a sampling time by carrying out the one-round sampling in a pattern part and then, the sampling in a surface part. CONSTITUTION:First, the one-round sampling in the pattern part is carried out, and then, the one-round sampling in the surface part is carried out, so that the influence of the eccentricity of a photosensitive body 121 is reduced, and the sampling time can be prolonged. After a density sensor PCN detects the ratio of the detected two type densities, it is necessary that the photosensitive body is rotated once and then, stopped with the turning on of all erasers before the stopping of the drum, so that the potential of the photosensitive body 121 is stabilized and toner is fixed on the photosensitive body 121. When the surface part is sampled, the image is not formed with the turning on of all erasers, so that the sampling of the surface part is carried out as an action at the time of stopping, and time to be taken for a detecting action can be shortened.

Title: Photograph printing processor
Inventor: TSUJI MASAAKI
IPC: G03B27/32
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To properly control the pressure of a photographic sensitive material, to obtain the print of a clear picture and to comparatively inexpensively manufacture an exposure part by specifying the main stop area of a cam follower set at a cam surface in order to keep a pressing pad in a pressing posture. SOLUTION: The main stop area of the cam follower 55 set at the cam surface 54b in order to keep the pressing pad 50a in the pressing posture is formed on a circular-arc 54c whose radius is identical to that of the outermost peripheral circle of a revolving locus plotted by the follower 55 in accordance with the rotation of a rotary shaft. Therefore, since the control accuracy of the stop position of the rotary shaft of a motor is comparatively low, a rocking member 54a is stopped in the prescribed posture even when it is stopped at an angle position where it overruns the original stop position within some angle range. Thus, even when the usual DC motor is used in an ordinary high actuation speed, the pressure of the photographic sensitive material by the pad 50a can be properly controlled and the print of the clear picture is obtained.

Thus the performance equivalent to that of conventional semiconductor pressure sensors is obtained. Since the ''Koval '' has a coefft. of thermal expansion approximate to the coefft. of thermal expansion of Si and since the silicon rubber is relatively soft after curing and the distance from the adhered parts thereof with the pellet up to the diaphragm is relatively long, thermal strains are adsorbed and no adverse influence is given upon the strain gauge.
