Title: Phase detector and method for detecting phase relation between two signals
Inventor: MYER ROBERT EVAN
IPC: H03D13/00
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To obtain a phase detector showing one absolute voltage with respect to each phase difference between ±180 deg. by nearly equalizing the amplitude of a second amplitude-adjusted distribution signal to the amplitude of a second input signal. SOLUTION: A splitter generates signals S32-1, S32-2 to respectively guide to a phase adjuster 34 and an attenuator 36. The signal S32-1, Sb are phase- shifted by phase adjusters 34 and 38 to generate output signals S34, S38. For example, the adjusters 34 and 38 are used for setting the absolute voltage of 0 volt for showing a phase difference 0 deg. between signal Sa and Sb. The amplitude of the signal S32-2 is adjusted by the attenuator 36 to generate a signal S36. The signal S32-2 is attenuated so that the signal S36 may be provided with nearly the same amplitude with the signal Sb. The signals S36, S38 are given to an adder 40 as inputs to generate a signal S40 as a result. The signal S40 is provided with nearly the same phase as the average phase of the signals S36, S38.

Title: Gas laser oscillator
Inventor: YAMASHITA ICHIRO
IPC: H01S3/038
Filed: 1988-10-31
Abstract: PURPOSE:To lengthen a laser gas in service life and to obtain a gas laser oscilla tor which can dispense with a switch of a main discharge circuit by a method wherein a grid electrode is provided between main discharge electrodes to induce a glow discharge. CONSTITUTION:For instance, a negative high voltage is previously applied between an anode 1 and a cathode 2 (capacitor 7 is previously charged with energy), and a positive high voltage pulse is applied to a grid electrode 3. If the grid 3 is formed of a coarse mesh of fine wires, a very intense electric field is induced near the grid 3, a corona discharge occurs in a streamer. As the corona discharge of a streamer occurs almost concentratively and uniformly, a discharge current hardly converges and the main discharge region is made to decrease uniformly in impedance. As gas is made to decrease spatially and uniformly in impedance, the energy stored in the capacitor 7 is uniformly sup plied to the discharge region to form a glow discharge and a laser oscillation starts.

Abstract: PURPOSE: To provide a C compiler with improved program development efficiency used when the high-speed processing of a game or the like is requested by providing a reservation function for preparing an instruction code for accessing data to an I/O port when it is described in a C source program. CONSTITUTION: When a special reservation function for the access of the I/O port is prepared and the function is described in the C source program, this C compiler prepares a CPU instruction code for accessing the data to the I/O port. That is, description is performed in a function form at a source program level, however, expression is performed as the assembly of instructions for accessing the I/O port directly at an object program level. The expression form of the source program at that time is defined as func (p);. Where, func is a function name and (p) is the address of an area for inputting and outputting the data of the I/O port. However, even though it is a function, but it is not a function when passed through the C compiler and the instruction of a CPU is directly generated.

Title: Method and apparatus for stencil printing
Inventor: SATO MITSUO
IPC: B41L13/04
Filed: 1990-10-12
Abstract: PURPOSE:To correct the printing operation corresponding to the state of a stencil base paper or the like by variably adjusting an increase of the pressing force of a platen supporting mechanism and a decrease of the rotating speed of a drum driving mechanism by a controlling means corresponding to the length of a pause when printing is started. CONSTITUTION:For example, if a power switch of a main body is turned OFF after printing is finished, a clock 23 starts counting of the pause in accordance with a detecting signal of a CPU 25. When a stencil printing apparatus 1 is activated to start printing, the CPU 25 detecting the start reads a predetermined controlling pattern from a memory 24 in accordance with the pause counted by the clock 23 and controls a drum driving motor 8 and a pressing force variable motor 17. The pressing force between a stencil base paper 4 and a printing paper 29 is increased and at the same time the transfer speed of the printing paper 29 is decreased by controlling the motors 8, IT corresponding to the length of the pause of the apparatus. Therefore, the printing operation is corrected corresponding to the permeating state of ink to the stencil paper 4. Thus it becomes possible to obtain good printing from the start even after a long pause.
