Title: Valve unit device
Inventor: TODA KATSUMI
IPC: F16K27/00
Filed: 1994-05-18
Abstract: PURPOSE:To improve the mechanical strength and pressure resistance of a valve body and to prevent the occurrence of breakage thereof by a method wherein a thick section box-form bottom plate is brought into close contact with the bottom surface of a base and flow passage forming grooves formed in the end faces, positioned facing each other, of the base and the bottom plate are united together to form a flow passage. CONSTITUTION:A valve body 40 is provided on both upper and lower sides of a base 1 with a cover plate 17 and a bottom plate 19. A plurality of valve parts, such as, a stop valve A with a check function, a quantitative valve B, and a solenoid valve C, are located on the upper surface of the base 1. In which case, the bottom plate 19 is formed in a thick section box-form state. Namely, a second flow passage forming groove 49 having a sufficient depth D2 is formed in the bottom plate 19 and formed in a box--form shape. A second flow passage forming groove 49 is united with the first flow passage forming groove 48 having a given depth D1 disposed on the bottom of the base 1 to form a communication flow passage L3. This constitution functions the peripheral wall part 19a of the bottom plate 19 as a reinforcing rib and improves a mechanical strength. Thus, even when fluid flowing through the communication passage L3 has a high pressure, the bottom plate 19 is prevented from being deformed.

Filed: 1980-07-29
Abstract: PURPOSE:To prevent decrease in resolution by shifting the optical frequency of the light entering the light receiving part of a laser radar comprising a light transmitting part and the light receiving part by an acoustic optical modulator, mixing a part of the transmitted light as local oscillation light, and performing heterodyne detection. CONSTITUTION:A light having the frequency nu1 from a master laser ML is divided into light paths (a) and (b) by a half mirror HM1. The light whose power is P2 is in the light path (b) is inputted into a detector D through a mirror 4 and HM2 as local oscillation light. The light in the light path (a) is intermittently flashed by a light switching means CH, amplified, e.g., by about 100,000 times by a TEA amplifier TA, and irradiated to the direction of (d). The light, which is attenuated to power P3 in a light path (e) due to scattering is bent by angle thetaapprox.=4 deg. in the acoustic optical modulator AO. At the same time, the frequency of said light is shifted by a driving frequency of the modulator AO. Said light is inputted to a detector D through a light path (c), a mirror 5, and the HM2, and mixed with the local oscillation frequency from the light path (b). Thus the frequency DELTAnu is obtained and sent to an intermediate frequency amplifier IFA. In this constitution, the stray light component is suppressed to about 1/1,000, and the decrease in resolution can be prevented.

Title: Nonlinear circuit
Inventor: HATANAKA HIROSHI
IPC: G01D3/02
Filed: 1993-04-08
Abstract: PURPOSE:To make possible simultaneous correction of temperature characteristics and nonlinear characteristics by constituting a nonlinear circuit of a first high order equation circuit, a sensor circuit, and an adder with each coefficient in the equation being set externally. CONSTITUTION:Differential output signal from a sensor circuit 1 is converted by a differential amplifier 2 into a signal end signal and also subjected to linear correction by a high order equation circuit 3. Both signals are synthesized at a predetermined ratio and amplified by a butter amplifier 4. The circuit 3 produces an output represented by a high order equation of differential input having coefficients being set externally. Since the coefficients a0-a2 are set externally, the coefficients a0-a2 can be provided with temperature characteristics using temperature sensitive resistors. This circuit can correct even such I/O characteristics as having temperature dependent nonlinearity. In case of correction using external temperature sensitive elements, temperature sensitive resistors P1-P3 have resistances variable with the temperature and thereby the coefficients a0-a2 also vary with the temperature. Consequently, variation amounts of the coefficients a0-a2 can be set freely by varying the resistances of the resistors R1-R7, P1-P3.
