Title: Preparation of concentrated liquid dispersion of photosynthetic bacteria
Inventor: IWAMURA JUNICHI
IPC: C12N1/20
Filed: 1984-08-21
Abstract: PURPOSE:To obtain the titled concentrated liquid which enables the size reduction of the apparatus, the use in a cold district, and the reduction of the running cost, by concentrating the culture product containing the living photosynthetic bacteria with an ultrafiltration membrane in the state containing the living cells. CONSTITUTION:A culture product containing the living photosynthetic bacteria is concentrated with an ultrafiltration membrane (e.g. cellulose acetate, nylon, cellophane, etc.) in the state containing the living bacterial cells. In spite of the small dimension and weight of the photosynthetic bacterial cell, the culture product containing the cells can be concentrated easily at high rate of concentration.

Title: Inkjet recording apparatus
Inventor: SAITO KOICHI
IPC: B41J2/045
Filed: 1989-07-05
Abstract: PURPOSE:To remove electrode reaction, while simplifying a circuit, improving the reliability and making it easy to detach a signal electrode, by impressing a constant voltage to a first electrode at the outer surface of an air nozzle plate and a second electrode within the ink and impressing a signal voltage to a third electrode at the rear surface of said air nozzle plate. CONSTITUTION:When the ink is discharged, the potential difference between a first electrode 11 and a second electrode 12 is 1000V. Since a voltage decrease of 400V is found at the rear side of an air nozzle plate 2, ink can be discharged by impressing 600V between a third electrode 13 and the second electrode 12. When the ink is not discharged, the potential difference of approximately 550V is set between the third electrode 13 and second electrode 12 in consideration of the stability when recording is not performed. Accordingly, if the signal voltage of 100V is given to the third electrode 13, it will invite the discharge of the ink. The signal voltage can be rendered small. When recording is not performed, a constant voltage, namely, OV and +550V are applied to the third electrode 13 and second electrode 12, respectively. When recording is performed, a signal voltage of a rectangular wave of -100V is given to the third electrode 13. The voltage applied to the second electrode 12 as an electrode within the ink is always constant, so that no electrode reaction is generated.

Abstract: PURPOSE:To increase the processing speed of a multiplying device by connecting the software to a ROM in a computer. CONSTITUTION:Both X and Y are fetched by registers R1 and R2 on a RAM 11b. Then 3 is stored in a loop control register (i) to read out a ROM2-12 by four times. Then XU and YU are delivered in the form of a synthetic address and this address is given to the ROM2-12 as an address signal. Here the corresponding result of multiplication is obtained at the output terminal of the ROM2-12 in the form of the data 13 after a prescribed access time. The data 13 is stored in a register B3 of a computer 11. Hereafter XU.YL, XL.YU and XL.YL are also treated in the same way and the results of these partial products are stored in the registers B2, B1 and B0 respectively. When the partial products of all combinations are obtained, a CPU carries out an addition P=B0+B1.2<4>+ B2.2<4>+B3.2<5>. Thus the result P of multiplication is obtained. Then the product P is delivered through a prescribed port of the computer 11 to complete a multiplying operation.

Title: Steering characteristic control device for vehicle
Inventor: ONUMA TOSHIO
IPC: B60G21/055
Filed: 1986-07-23
Abstract: PURPOSE:To establish steering stability both at the time of straight forward running and turning for a vehicle by adjusting the roll rigidity ratio of front to rear for controlling steering characteristics to the under-steering side when the vehicle has reached a predetermined range set with the steering angle and the speed thereof. CONSTITUTION:The steering angle and the speed of a vehicle M1 are detected respectively by detecting means M2 and M3. And when the results of the detection have reached a predetermined range set up with the steering angle and the speed, a control means M5 controls a roll rigidity ratio change means M4. In other words, when the vehicle M1 has turned into a straight forward running condition at a relatively high speed, the roll rigidity ratio of front to rear for the vehicle M1 is adjusted and steering characteristics are controlled to the under-steering side. According to the aforesaid constitution, the steering characteristics in straight forward running are shifted and set to the under- steering side without any adverse effect upon the steering characteristics of the vehicle M1 in turning. Therefore, steering stability can be maintained concurrently at the time of the turning and the straight forward running of the vehicle M1.

CONSTITUTION:A capacitor C2 is charged by the current obtained from a constant current source 46 when a head switching signal (a) is in a low level, and the change of the potential at a point (c) is in a form of triangular waves having a certain gradient. When the head switching signal is in the high level, the electric charge charged in the capacitor C2 is discharged through a resistance R4, and a waveform (c) is obtained. At this time, it is sufficient if the current of the constant current source 46 is set to such value that the potential difference between both ends of the capacitor C2 is a potential difference required for driving a bimorph for an extent corresponding to one track pitch in 1/60sec when the capacitor C2 is charged. The potential at the point (c) is subtracted from that at a point (b) by a subtractor 43 to obtain a bimorph driving pattern signal which has a gradient shown in a figure (d).

IPC: B65D1/16
Filed: 1992-07-02
Abstract: PURPOSE:To enable a can to axially collapse under pressure in a simple manner by providing a nodal line at the top of each ridge of a bellows. CONSTITUTION:A can is formed substantially in a cylindrical shape having top end 1 provided with a pull-tab 2 and a bottom 3. The side wall 4 consists of a bellows in structure. The furrows of the bellows are directed along a circumference of the side wall 4 so that the axial application of a compressive force to the can, when it contains nothing inside, makes it axially collapse. It is most practical to form the bellows by drawing so that in the bellows the furrows and the top of the ridges are rounded in outline. By virtue of the bellows the can is capable of axially collapsing under pressure in a simple manner.

Title: Electrolytic surface treatment and device therefor
Inventor: SATO KUNIO
IPC: C25F7/00
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: Not to leave a touch trace of a receiving frame to an end part by fixing one end part of a material to be treated to a support member capable of being energized from a carrier bar, receiving the other end part with a receiving frame reciprocating in a longitudinal direction of the material to be treated and conducting a surface treatment while reciprocating the receiving frame. SOLUTION: One end part of a material 4 to be treated is fixed to a support member 2 made of a conductive material which is fixed to a carrier bar 1 for supplying electricity to the material 4 to be treated, with a bolt 21 or an Al wire, the other end part is freely inserted into a receiving frame 3 oscillating up/down, thus the material 4 to be treated is set. The receiving frame 3, which is arranged on the carrier bar 1 or is hung to the other means and is connected to a reciprocating means 5, is reciprocated in a longitudinal direction. By this method, since a fixing work is done sufficiently only at one end, not only work efficiency is high, but also a yield is improved since the end part, where a touch trace out/removed after surface treatment, as the like, remains is only for one end part alone.
