Abstract: PURPOSE:To improve measurement accuracy and enlarge a measurement span by stabilizing reference length by means of feedback control and improving its accuracy. CONSTITUTION:In a frequency stabilizer comprising a gas cell 8, a half mirror 9, etc., light is branched by the mirror 9. One of the light beams is condensed by a lens 10 to be detected by a photo diode (PD) 11. The other light beam, after passing through the cell 8, is condensed by a lens 12 to be detected by a PD 13. An output of the PD 13 and an output of the PD 11 are input to a non-inverting and inverting terminals of a comparator 22, respectively. When a switch is changed over to a terminal B side, a feedback loop is structured wherein an output of the comparator 22 is fed back to an LD (frequency variable laser beam source) 1, and frequency of the LD 1 is stabilized to frequency of an absorption peak of the cell 8. With respect to the frequency of the LD 1, variation by a sweeper 24 and stabilization by the frequency stabilizer are performed by changeover by a switch controller 23. A sample & hold control signal SC is output to sample & hold circuits 18, 20 synchronized with the changeover, thereby performing stabilizing control of reference length.

Title: Manufacture of gray shadow stencil
Inventor: HORUFUAATAA JIIKUFURIIDO
IPC: G03F7/12
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To manufacture a gray shade stencil with higher quality by extending a grid up to an end of a pattern continuously and locating the patterns adjacent to each other. SOLUTION: A grid is arranged so that a mesh cross point 30 of the grid net is in matching with a corner point 32 at the lower left position of an additional image 14. Other adjacent mesh cross point 34 is obtained new an end point 33 at the upper left point of the additional image 14. Furthermore, a line in a direction of tying a corner point 32 with the grid net mesh cross point 34 has an angle dϕ with respect to the left end of the additional image 14. Thus, the grid mesh cross point 34 is accurately located to the left end by turning the grid by the angle dϕ. Then the grid is magnified or reduced so that the grid mesh cross point 34 is in matching with the corner point 33. Thus, correct matching of the grid at an adjacent point 36 is realized by the grid located at the same position at all adjacent points 36 at the same time.  Thus, the grid is continuously extended up to an end of a pattern and patterns are located adjacent to each other.

Title: Offset compensating circuit
Inventor: KOE SHINICHI
IPC: H03M1/10
Filed: 1984-08-30
Abstract: PURPOSE:To effectively compensate the deterioration in offset characteristic, by charging a capacitor for a prescribed period immediately after making power supply by switching switches and outputting a voltage necessary for compensating an offset. CONSTITUTION:A control circuit 3 switches switches 7 and 8 so as to select sign signals from a terminal 1 during a previously fixed period immediately after making power supply. When a current source 4 charges a capacitor 6 in the forward direction, another current source 5 simultaneous charges the capacitor in the negative direction. During the period, the sign signal from the terminal 1 becomes a signal following up an offset voltage by means of the circuit 3 and a voltage necessary for compensating the offset is outputted from an output terminal 9. When the previously fixed period has passed from the power supply making, the circuit 3 switches the switches 7 and 8 so as to select the output of a pulse generator 2. As a result, offset compensating operations which are the same as those made by conventional sign bit integrating system offset compensating circuits are performed.

Abstract: PURPOSE:To simplify the scale of the self-diagnostic circuit by outputting an input PCM signal without any modification when the signal is not an object of ADPCM code conversion, generating a test signal inbetween, inputting the test signal to a code converting circuit and deciding its output. CONSTITUTION:The PCM signal from an input terminal 1 is compared with channel information from a channel information storage circuit 3 by a comparing circuit 5 to decide whether or not the ADPCM code conversion is required. As a result, when the code conversion is required, code conversion is applied by a code converting circuit 6 and the result is outputted to an output terminal 2 via a selection circuit 7. When no code conversion is required, the input PCM signal is outputted as it is via the selecting circuit 7, a test signal is generated from a test signal generating circuit 4 inbetween and the code conversion is applied by the code converting circuit 6 via the selecting circuit 5 and the propriety of the output is decided by a deciding circuit 8. Thus, self-diagnosis is applied in an idle time with simple circuit scale.

Title: Francis water wheel
Inventor: NAGAFUJI TOMOTAKE
IPC: F03B11/04
Filed: 1981-11-13
Abstract: PURPOSE:To improve the vibration strength by defining such that the specific water wheel speed ns<=170, ns>=20, 15/H<1/2> while Zg=20, 22, 24, 30 when Zr=15 assuming the number of the runner vane is Zr, the maximum head of the water wheel is H and the number of the guide vane is Zg. CONSTITUTION:In a Francis water wheel, the size of the main machine can be reduced in the range of the water wheel specific speed ns<=170 while the efficiency is improved by increasing the specific speed, but the rigidity of the runner will deteriorate to lower the inherent vibration thus to susceptible to resonate with the frequency of the hydraulic exciting force due to the relative function betwen a guide vane and a runner. The resonation can be avoided by properly selecting Zg from five pairs such as Zg=20, 22, 24, 30 for Zr=15 and Zg=22, 24, 26, 32 for Zr=16, etc. assuming Zr is the number of the runner vane while Zg is the number of the guide vane.
