Title: Composite machine
Inventor: SENBA KEI
IPC: G06F3/12
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To confirm a device mode via a host user and also to switch the device mode at the host side. SOLUTION: When the information is received from a host (S1), a CPU temporarily stores the received information in a memory (S2). A device notifies the host of the present mode status information (printer/FAX mode) (S3) and also requests the host to switch the device mode or not. The CPU waits for a reply to be given from a host user for the device mode input information (S4). When the replay is received from the host user in a fixed time, the CPU decides whether the information received from the host is identical with the printer output information or the FAX transmission information (S5). If the printer output information is confirmed, the CPU reads out the stored information and prints them out (S6). If the FAX transmission information is confirmed, the CPU recognizes the information coincident with the information on the sending destination out of the stored information (S7).  Then the CPU reads the communication device number out of the memory and automatically sends the information received from the host to the communication device of the sending destination (S8).

Abstract: PURPOSE: To require only one thyristor, to make usable an inexpensive motor- driven machine and to reduce the cost in washing by obtaining a prescribed on/off time of the thyristor based on data with 0-360 degrees in an AC power source as a unit.

Then, the thyristor 5a of a photo-thyristor 5 is turned on only in case of the 'H' level in the signal so that the AC power source of the voltage waveform is impressed on the motor-driven machine 4 for the washing machine and also the number of rotation in the motor-driven machine 4 is controlled by the AC power source.

Filed: 1985-11-26
Abstract: PURPOSE:To reduce insertion loss and to reduce the size and cost of an optical demultiplexer by uniting an optical branching device and the optical demultiplexer with each other. CONSTITUTION:Natural light with wavelength lambda2 is separated by a polarized wave separating element 2, where a P polarized wave component is passed and an S polarized wave component is reflected.

The P polarized wave component is passed and coupled with an output fiber 6 and the S polarized wave component is reflected and coupled with an output fiber 5. Light with wavelength lambda1, on the other hand, is incident on an input fiber 10 and then converted by a lens 9 into parallel light, which is passed through the dielectric multilayered film filter 7 and reflected totally by the polarized wave separating element 2 without being separated because its wavelength is short, so that the component is coupled with an optical fiber 4. Namely, light beams with wavelengths lambda1 and lambda2 are demultiplexed by the dielectric multilayered film filter 7 and the light with wavelength lambda2 is branched by the polarized wave separating element 2, so that two-way transmission of wavelengths lambda1 and lambda2 is realized.

Title: Electron beam exposure method
Inventor: KAI JUNICHI
IPC: H01L21/30
Filed: 1984-12-17
Abstract: PURPOSE:To implement super-miniaturization of semiconductor devices and the like and to implement high degree of integration, by adding the correcting amount for an exposing position to the deflection of an electron beam, performing required electron beam exposure, and excluding the deviation of a pattern position due to charge up. CONSTITUTION:A position detecting mark is provided at, e.g., a corner where exposure is performed at the last time, in one chip. The position detection of the mark is performed before and after the required exposure of the chip. Thus the detected values (X1, Y1) of the first position and the detected values (X2, Y2) of the second position are obtained. As the amount of drift (DX, DY), DX=X2-X1 and DY=Y2-Y1 are obtained. Then, a drift correcting amount DELTAX is obtained by a linear interpolating method by expressions DELTAX=DXn/N and DELTAY=DYn/N, where T is an exposure time required for one chip, N is the number of clock pulses included in the exposure time T, and (n) is the sequence number of the clock pulse at an arbitrary shot point (n=0  N-1). The correcting amounts are added to coordinate values XOUT and YOUT, and the coordinate values controlling the electron beam are made to be X=XOUT+DELTAX and Y=YOUT+DELTAY. Thus the drift of the electron beam due to the charge up of a wafer is corrected.
