Title: Rectifier
Inventor: NISHINO TOSHIO
IPC: H02M7/06
Filed: 1981-01-19
Abstract: PURPOSE:To reduce the loss and protect a rectifying element from application of the high reverse voltage by applying a secondary winding to a smoothing circuit choke coil connected to the output terminals of a rectifying circuit. CONSTITUTION:A secondary winding N2 for bias is applied over a primary winding n1 of a smoothing circuit choke coil L1 and the voltage induced in a secondary winding N2 of a transformer T1 is applied to this secondary winding n2 via a resistor R1 and a diode D2 which is of the same polarity as a diode D1. The load direct currentIflows to the conductive direction of the diode D1 by the induced voltage in the secondary winding N2 of the transformer T1 and simultaneously the direct current i flows in the secondary winding n2 for bias, so that a magnetic core of the choke coil L1 is saturated and the loss is reduced. When the reverse voltage is applied the diode D1 is not conductive and the diode D2 connected to the secondary winding n2 is not conductive either. Accordingly the direct current i does not flow and the magnetic core of the choke coil L1 is not saturated and has high impedance, so that the high reverse voltage is not applied directly to the diode D1.

Abstract: PURPOSE:To easily execute gain control with high accuracy by monitoring an internal gain by the signal from the optical detecting regions provided on the light input/output side of the gain control region of a laser amplifier and controlling the current quantity of the gain control according to the monitor output thereof. CONSTITUTION:The laser amplifier A consists of clad layers 20, 21 which are different in channel from each other. The upper clad layer 21 forms a 3-electrode structure. Electrodes 22, 24 on the input side and output side are optical detecting regions where the intensity of the light signal propagating in the respective active regions is detected as current. The central region is the gain control region 23. The two signal component amplitudes obtd. from the electrode 22 and the electrode 24 are divided by a divider 25 of a signal processing section. The value obtd. in such a manner and a reference signal REF are compared by a differential amplifier 26 to obtain an error signal. A current source 27 which supplies driving current to the electrode 23 is controlled according to the error signal. The gain control is thus easily executed with the high accuracy.

Abstract: PROBLEM TO BE SOLVED: To provide a computer disk drive system having a buffer to which a data preread/prefetch principle is selectively established by including a principle prefetch controller, etc., to receive the data from a user and to produce a prescribed signal as an answer to the data request. SOLUTION: A prefetch principle controller, etc., is prepared to receive the data from a user and to produce a prescribed signal as an answer to the data request. In this system, a disk drive controller 26 can selectively prefetch or interrupt the preread of data to a buffer 24. Thereby, a prefetch principle controller 32 instructs the prefetch of the preread of data to the buffer 24 when a request is received to obtain only the data that are stored in a disk 22. The controller 26 also includes a non-prefetch principle controller 34 which prevents the prefetch of the preread of data to the buffer 24 in the same situation where the prefetch should be originally permitted by the controller 32.

Title: Focusing unit of electron-beam device
Inventor: NAMAE TAKAO
IPC: H01J37/21
Filed: 1978-01-25
Abstract: PURPOSE: To make it possible to irradiate invariably a sample with electron-beam flux in the smallest aberration circle state even if the electron-beam flux is astigmatic.  
     CONSTITUTION: Information generated from sample 11 through electron-beam irradiation is transmitted to automatic focusing unit 16 and display unit 17 by way of detector 14 and amplifier 15. With a start commanded by an operator, timing circuit 18 sends a signal to deflecting coils 13X and 13Y to allow electron beam EB  to attain a circular or oval scan repeatedly, and also sends signal (a) synchronizing  with the circular scan to automatic focusing unit 16 to start its operation. Namely,  the unit 16 integrates the variation of a detection signal during the circular scan and transmits signal (b), at the time of a current value of an object lens when the variation is the smallest, to fix the current to the value. By this current value, the smallest aberration circle can be obtained. A clear electron microscope image can therefore be obtained by allowing an electron beam to make a raster scan in the smallest abberation circle state with the change-over switch returned.

The electrical signal from the element 13 is fed back for controlling the output of the element 12.  As the element 12 is arranged in opposition to the elements 13 and 15, the respective optical paths between the element 12 and the elements 13 and 15 are formed into a linear shape.
