Title: Longitudinally connection type differential amplifier
Inventor: NAKAMOTO HIDENOBU
IPC: H03F3/347
Filed: 1989-05-22
Abstract: PURPOSE:To make the size of the amplifier small by providing an input side level shift circuit moving the operating point of an input signal, a differential amplifier circuit applying differential amplification operation of the output of the circuit, an output side level shift circuit connecting to the differential amplifier circuit and matching the operating point of the output signal and a constant current source for stabilizing the circuits. CONSTITUTION:An output signal operating point is moved to a standardized output operating point by providing a level shift circuit 6 to the output side to make the output signal operating point coincident with an input signal operating point. Then differential amplifiers are connected in cascade without using a coupling capacitor. Moreover, a level shift circuit 5 is provided to the input side to increase the input impedance thereby facilitating the parallel connection of cascade connection circuits. Furthermore, a constant current source 2 is used to eliminate the effect of the fluctuation of an external power supply Vee to make the operating point of each component and its level shift stable. Thus, a connection pin for an LSI for the coupling capacitor is not required, an external pin number and externally mounted components are saved, the component mount area are decreased and the device is made small in size.

Title: Semiconductor laser device
Inventor: AOYANAGI TOSHITAKA
IPC: H01S5/00
Filed: 1986-06-03
Abstract: PURPOSE:To obtain a semiconductor laser device with window structure for a high output, which does not deteriorate a threshold and differential quantum efficiency, by forming an N diffusion or N implantation region containing at least an active layer near the end surface of a resonator. CONSTITUTION:A semiconductor laser device consists of an ohmic electrode 1, an insulating film 2, an N-type cap layer 3, an N-type clad layer 4, a P-type (or intrinsic) active layer 5, a P-type clad layer 6, a P-type substrate crystal 7 and N diffusion or N implantation regions 8. When currents are injected to the N side from the P side through the ohmic electrode 1, currents concentrate to sections (stripes), in the upper sections of which there is no insulating film 2, in the active layer 5, thus generating laser oscillations. Laser beams are propagated in the stripes, and radiated from the end surface of a resonator. Since the implantation regions 8 are shaped near the resonator, a section in the vicinity of the resonator is made transparent with respect to laser beams due to the Burstein shift effect, and light is not absorbed, thus improving an output.

Abstract: PURPOSE:To make it possible to reduce the vertical gap between drag rollers and to reduce the height of a rotary press, by enabling an auxiliary slitter to be moved in a direction intersecting the feeding direction of a web, in the condition of being directed in the direction of a cutting line of a main slitter knife. CONSTITUTION:A gripping part 24 constituted of a traction member 22 comprising three coiled springs grips a gripper margin 3b' of a GS paper 3b at the time of passing the paper 3b through turn bars 14, 15. In view of this, an auxiliary slitter knife part 30 is disposed on the front side of the gripping part 24 so that a full-width web 3 is not cut normally at the center of the width thereof by a main slitter knife 8 on the drag roller 1 but is cut to make the GS paper 3b wider by the width of the traction member 22 after being passed through the drag roller 1. An auxiliary slitter knife receiver is disposed opposite to the auxiliary slitter knife part 30, with the web 3 therebetween. Thus, there is no need for a cutting means and an operating cutter other than the two slitter knives, so that the overall height of a printing press can be reduced.

A highly doped n-type silicon layer 9, which is contacted with the lower surface of the connecting part 7, is provided in the semiconductor device. The highly doped n-type silicon layer 9, which is contacted with the lower surface of the connecting part 7, is formed before the formation of the silicon interconnection 3. Therefore, n-type impurities are supplied to the connecting part 7 from the n-type silicon layer 9 by heating before the formation of the aluminum interconnection 5, and the impurity concentration becomes high. The formation of a P-type silicon region, which is a problem, is prevented. Thus, the connection of the aluminum interconnection and the n-type silicon interconnection can be stabilized.

Abstract: PURPOSE:To provide a blood bag in which a filling means for filling a blood- preserving agent into a bag body (master bag for sampling whole blood from a donor) is improved. CONSTITUTION:This blood bag 1 is a capsule (1') having a bag body (master bag for sampling whole blood from a donor) filled with a solid concentrate-like blood preserving agent or a blood bag (2') filled with a 2' solid blood preserving agent. The blood bag 1 allows the packing of the capsule 5 (solid blood preserving agent 5a) thereinto when making the body 2 (master bag 22) into a bag 1 to eliminate the need for a filling process of a preserving liquid which requires equipment and time as in the production of the blood bag in the past. The filling of the body 2 (master bag) with the solid blood-preserving liquid allows sterilization by a gas, for example, simply by filling a plastic bag having a gas permeating back label mounted thereon. This bag eliminates the need for high pressure steam sterilization and a packing process to a costly laminate bag as in the past thereby achieving an upgrading of production efficiency significantly.

Title: Focusing method
Inventor: SATO YASUSHI

Filed: 1992-04-24
Abstract: PURPOSE:To focus an objective lens based on a focusing error signal by storing a peak value of a photodetector. CONSTITUTION:An objective lens 14 is raised, and a switch SW1 is shifted to a side A. A quadrant photodetector 16 applies a reflected light of a disk 10 to a peak detector 22 through a gain amplifier 20. A peak value is stored in a memory 28 through an A/D converter 24 and a microprocessor 26. In this case, two peaks are generated by a real focus signal and a similar signal. The peak value of the similar signal generated by reflection of a light on a boundary between a transparent board and the air is always smaller than that of a focusing error signal generated by reflection of the light. Then, the switch SWI is shifted to a side B, and an output of the amplifier 20 is supplied directly to the converter 24. When the focus of the lens 14 is again focused at a reflecting film, the lens 14 is raised, until the processor 26 receives the peak value, and the lens 14 can be rapidly focused since the peak value of the focusing error signal is known.
