Title: Centrifugal separator treating liquid
Inventor: HORON BII EBERII
IPC: B04B5/04
Filed: 1982-07-09
Abstract: A self-balancing contrifuge has a rotor (102) driven by a shaft (56) journalled in bearings (54, 114) supported by upper and lower flexible bearing mounts (120, 48). The horizontally flexible bearing mounting planes thus provided give a greater degree of freedom for the axis of rotation (R) of the rotor to move into a coincident relationship with the angular momentum vector of the rotor as it changes with dynamic imbalance thereby to compensate for any imbalance which may occur in the centrifuge rotor during centrifuging. The centrifuge is particularly intended for use in processing blood.

Title: Integrated amplifier
Inventor: YAKOBU MURUDAA
IPC: H03G1/00
Filed: 1994-06-01
Abstract: PURPOSE: To obtain an integrated amplifier which is attained simply and effectively concerning a price while maintaining a correctly regulated gain rate. CONSTITUTION: The gain rate As of the integrated amplifier adjusted by an auxiliary amplifier 2 is decided by the ratio of two on-chip resistors R1 and R2 and the ratio of the dimensions of the transistors of the long tail pair circuits 6-2 to 6N of a signal amplifier 3 and the dimension of the transistor of the long tail pair circuit 6-1 of the amplifier 2. A resistance ratio and a ratio between perfect circuits are remarkably precisely attained by an integrated circuit. Consequently, the precision of a gain rate As is improved. As the dimensions of the circuits 6-1...6-N of the amplifiers 2 and 3 are made equal, the gain ratio As is not related with supply voltage and a temperature in a wide range when the adjusting voltage and the adjusting current of the transistors corresponding to these circuits 6-1...6-N are the same.

By making an opening and using an impurity having low diffusion speed, such as Sb, n ++ -type region 13 is formed by diffusion. Next, by removing film 12, thick epitaxial n-type layer 14 is grown on the entire surface. By the heat treatment operated at this time, region 13 is caused to project in layer 14. Subsequently, by using the conventional method, SiO 2  film 15 is coated on layer 14. BY making an opening, mesh-shaped p + -type gate region 16 is formed by diffusion. An n + -type source region 17 is provided between these, and they are respectively fitted with gate electrode 18 and source electrode 19, and thereby J-FET is formed. By this, even if layer 14 is made thick, the electrostatic capacity between gate and source becomes small, so that the high-frequency charactristics are improved.

Abstract: PURPOSE:To avoid wasting a thermal transfer film, by a method wherein a thermal transfer film is taken up in synchronism with the moving velocity of a carriage at the time of printing by a thermal head, and is taken up at a slower speed when returning the carriage in a non-printing condition. CONSTITUTION:When printing, the carriage 1 is moved in the direction of arrow A, a printing head 5 is pressed against a platen 6, and generates heat according to a printing signal. In this case, a gear 18 is rotated in the direction of arrow C, while a gear 19 is rotated in the direction of arrow D, and a take-up reel 9 is rotated, whereby the thermal transfer film 7 is taken up in synchronism with the moving velocity of the carriage 1 under a slip clutch action due to friction with a printing paper. When returning to a starting end, a timing belt 11 is moved in the direction of arrow F, an arm 15 is moved rightward by friction, gears 18, 20 are engaged with each other, and rotation is transmitted to the reel 9 through a gear 23, pulleys 25, 26 and a belt 27. Since the diameter of the gear 23 is larger than that of a gear 21, the transfer film is taken up by only a little amount. Accordingly, the thermal transfer film once used is not reused, and waste thereof is reduced.

Title: Reduction-enlargement rate controller of copying machine
Inventor: SUZUKI TAKANOBU
IPC: G03G21/00
Filed: 1982-07-12
Abstract: PURPOSE:To set a reduction-enlargement rate automatically according to specified copying form size, by allowing a reduction-enlargement rate control part to discriminate the original size on the basis of the conveyance time of the original moving toward a platen at a predetermined speed. CONSTITUTION:When the original 40 is inserted, a motor 13 conveys the original 40 to the position of an in gate 14. An input sensor 11 outputs a detection signal to a controller 1 in said process. Once a start print button 30 is operated, the original passes over the sensor 11 at a constant speed and its passing time is measured to decide on the size of the original. The reduction-enlargement rate is calculated on the basis of the original size and the control command for the reduction-enlargement rate is sent out to a controller 25. Thus, the original size is discriminated and the reduction-enlargement rate is calculated from the ratio to specified form size, so the reduction-enlargement rate need not be reset every time an original of different size is copied.
