Title: Probe for spectral analysis of laser beam
Inventor: KAKUYAMA KOUZOU
IPC: G01N21/63
Filed: 1980-03-13
Abstract: PURPOSE:To ensure a highly efficient transmission for an excited light especially for the light of the vacuum ultraviolet region, by using the inner surface of a lens barrel that leads an incidence of a laser beam for a reflecting mirror surface that reflects and transmits the excited light including the vacuum ultraviolet region. CONSTITUTION:The inner circumference wall of an L-shaped lens barrel is polished and finished into a reflecting mirror surface S with vapor desposition of aluminum. The exhaustion port 6 is connected to the exhaustion system to secure a vacuum state in the barrel 1. Then the laser beam oscillated from the laser oscillator 5 travles within the barrel 1 through the prism 9 and magnifying lens 5 and is converged by a condenser lens 2 to irradiate the sample 8. With this irradiation, the vacuum ultraviolet rays among the excited beams on the surface of the sample transmit through the lens 2 to be led backward in the barrel 1 and then propagates with a repetition of reflection on the surface S to reach the incident slit 11 of a spectroscope 10 after turning to the lens 4 via a reflector 3. As a result, a spectral anaylsis is possible for the component elements having the spectrum in the vacuum ultraviolet region such as C, P and S, etc. that are primary components in the steel.

IPC: H03L7/099
Filed: 1990-02-14
Abstract: PURPOSE:To realize the phase detection synchronization system immune to line noise and frequency and phase offset by adopting the trial mode adjusting sequentially the initial phase and the selfrunning angular frequency and the normal mode using a phase detection synchronization circuit to take phase synchronization. CONSTITUTION:When frequency detuning exists between a frequency component of an input digital signal and a reference frequency from a COS transformation device 15, a DC component is generated in an output of a loop filter(LF) 11. It is detected by an angular frequency detuning estimate device 24 to estimate the angular frequency detuning degree. Moreover, when a phase difference exists, a pulse signal component is generated in the output of the LF 11 and an initial phase difference estimate device 23 detects it to estimate the initial phase difference. The initial phase of an initial phase generator 14 and a self-running angular frequency of a self-running angular frequency generator 13 are corrected respectively by using the estimated angular frequency detuning degree and the initial phase difference. Then PLL processing is applied to a same input signal stored again and the estimate is repeated till the synchronization state is reached in the trial mode. Then the PLL processing in the normal mode is selected.

Title: Control of print registration
Inventor: INO MITSUYASU
IPC: B41F13/12
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To clear a malregistration at an early time when starting a printing process and thereby shorten time required for a printout by setting and changing a control gain to be used for calculating the amount of operation of a compensator roll based on an amount of malregistration detected on the outlet side of a downstream unit and in compliance with the velocity of a web transport line. SOLUTION: A control gain calculation part 22 calculates an appropriate value complying with a change in the velocity of a line, based on every control grain obtained when the line velocity is set to a specific value, as a registration control device is operated under PID control. If respectively appropriate control gains are calculated based on a line velocity(v) entered to the control gain calculation part 22, a transfer time calculation part 24 calculates the amount of variation of the length of a web W which is required for setting the amount of malregistration (en) of a registration sensor 18 to the tolerable range, that is, the amount of transfer (the amount of operation) of a compensator roll, in accordance with the amount of malregistration (en) as a base value.  The amount of transfer (distance) is set by a transfer time(t), as the transfer velocity of the compensator roll is constant.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent burrs and delimination on the side of products by causing burrs and delimination of circuits due to cutting on the side of unnecessary parts at the time of cutting products from a composite material board of a molded part with plated circuits. SOLUTION: A composite material board 3 is to be cut along lines a, b, c and d to form three-dimensional circuit boards.

The board is cut along the lines a and b crossing over through- holes 5 to separate individual plated circuits 2, in such a way that the individual plated circuits 2 are connected at plating parts 14 for conduction in order not to break electrical supply through plating. Since the parts of cutting of the composite material board 3, where the angle between the direction of tangent line of a cutting blade and the horizontal direction is large, are cut in such a way that a metal film on the forward inner side of the through-hole 5 is pressed toward the molded part 1, no burr or delimination will be produced on the metal film.

Title: Tube diaphragm pump
Inventor: KONISHI YOSHIAKI
IPC: F04B43/10
Filed: 1995-02-21
Abstract: PURPOSE: To allow a tube diaphragm pump to have a simple structure and be miniaturized by including a chemical-resistant cylinder forming an internal space that sucks or delivers fluid according to hydraulic pressure, an elastic cylinder surrounding the outside of the chemical-resistant cylinder, and a pressure transfer medium packed between the cylinders. CONSTITUTION: This tube diaphragm pump includes a chemical-resistant cylinder 3 provided to surround the central axis of a pump main body 2 and forming therein a space 24 for sucking and discharging liquids, and an elastic cylinder 4 provided to surround the outside of the chemical-resistant cylinder 3. The chemical-resistant cylinder 3 and the elastic cylinder 4 are fixed at both end openings of the pump main body 2 by means of fixing members 5. When a liquid in a hydraulic pressure chamber is pressed by a suction and pressure means, the elastic cylinder 4 shrinks accordingly. The shrinkage of the elastic cylinder 4 results in the application of pressure to a pressure transfer medium packed between the elastic cylinder 4 and the chemical-resistant cylinder 3. The tube diaphragm pump thus has a simple structure and can easily be miniaturized.
